If you are looking for a reliable alternative to the SR2512JK-7W3R3L resistor, then TGL251220F3R30E04D is a choice worth considering. This is a replacement model with performance matching and relatively more stable supply.
Model analysis and parameter comparison
SR2512JK-7W3R3L is a high-power surface mount resistor, and its name is usually interpreted as: "SR" represents the series, "2512" is the package size (6.35mm x 3.18mm), "7W" represents the rated power, "3R3" represents the resistance value of 3.3 Ω, and "L" may refer to accuracy or special characteristics.
As an alternative, TGL251220F3R30E04D is a surge resistant surface mount resistor produced by EVER OHMS. The key parameters and comparisons are as follows:
Characteristic parameter SR2512JK-7W3R3L (original model) TGL251220F3R30E04D (alternative model)
Rated power 7W 2W
Resistance value 3.3 Ω 3.3 Ω
Package size 2512 (6432 metric) 2512
Accuracy (tolerance) is usually ± 5% ± 1%
Core feature: High power surge resistance
Selection and Alternative Suggestions
Choosing TGL251220F3R30E04D as an alternative is mainly based on the following considerations:
Parameter matching: The resistance and packaging size of the two are exactly the same, which is the basis for implementing replacement.
Feature enhancement: Compared with ordinary high-power resistors, TGL251220F3R30E04D clearly has surge resistance characteristics. If there is a risk of momentary high voltage or current surge in your circuit (such as power input, motor drive), this resistor can provide better protection.
Higher accuracy: ± 1% accuracy can meet more precise circuit requirements.
Supply and Support: As a mature model of Tian'er Technology, TGL251220F3R30E04D can obtain stable supply and original technical support through authorized agents.
>Important notice: According to the query information, TGL251220F3R30E04D is currently in a discontinued state. When making actual purchases, it is essential to confirm with the agent whether there is available inventory for sale or to inquire about the availability of new generation replacement models that are functionally compatible.
Explanation on power difference: The original model in the table is labeled as 7W, while TGL251220F3R30E04D is 2W. This requires you to evaluate it based on the actual circuit:
If the actual working power is much lower than 2W, it can be directly replaced.
If the power demand is high but there are intermittent surges in the circuit, the anti surge characteristics may just be suitable.
If the power demand is indeed close to 7W, it cannot be directly replaced and other models with matching power levels need to be found.
Recommended agents and reasons
To ensure the purchase of genuine products and obtain professional support, it is recommended to purchase TGL251220F3R30E04D through official authorized channels. The following are recommendations from two authorized agents:
1. Shenzhen Shunhai Technology Co., Ltd
Recommendation reason: As an authorized agent of Tian'er Technology, they can provide genuine factory guarantees and legitimate supply channels. For customers who require bulk procurement or long-term cooperation, such agents can usually provide deeper technical support, more flexible business terms, and localized customer service, especially suitable for enterprise customers.
2. Hua Nian Mall
Recommendation reason: As an online authorized agent of Tian'er Technology, Huanian Mall provides a convenient and efficient procurement platform for engineers, procurement, and small and medium-sized enterprises. The online platform provides intuitive model queries, flexible small orders, and fast logistics speed, making it very suitable for R&D trial production, sample application, or small batch emergency procurement needs.
Procurement and Replacement Checklist
Before making the final decision to replace and place an order with TGL251220F3R30E04D, it is recommended to follow this checklist for verification:
1. Confirm inventory: Contact the agent and first confirm whether TGL251220F3R30E04D is in stock or has a supply cycle.
2. Verification parameters: Request the complete data manual of TGL251220F3R30E04D from the agent or verify it on their official website to ensure that all electrical parameters meet your circuit requirements.
3. Evaluate power: Re calculate the actual power consumption of the resistor position in the circuit to confirm whether it is within the safe range of 2W.
4. Sample application: When conditions permit, a small amount of TGL251220F3R30E04D sample can be applied for actual machine testing to verify functionality and temperature rise.
I hope the above information can help you smoothly complete component selection and procurement. If you could provide more information about the specific role of this resistor in the circuit (such as whether it is used for current sampling, buffering, or discharging), perhaps you could provide a more detailed analysis.
