Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR150EV is determined by strict equivalence in the following critical parameters:

• Resistance value: 150 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Application: Current Sense

Substitute parts are grouped into two categories based on power rating compatibility:

Category 1: Direct Equivalents (1W Power Rating) Parts with identical 1W power rating and all core electrical parameters matching the original specification.

Category 2: Enhanced Substitutes (2W Power Rating) Parts with increased power rating capability while maintaining all other electrical parameters. These provide additional thermal margin for the same application.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with the original part's environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

PT2512FK-070R15L (YAGEO) This part is an active production substitute with identical electrical specifications to the LVC25FR150EV. It features automotive AEC-Q200 qualification, providing enhanced reliability for demanding applications. The temperature coefficient of ±75ppm/°C is superior to the original part. Extended operating temperature range (-55°C ~ 155°C) offers broader application flexibility. Recommended for new designs and production transitions requiring automotive-grade components.

CRM2512-FX-R150ELF (Bourns Inc.) This part provides a 2W power rating while maintaining all core electrical parameters of the original 1W specification. The increased power capability offers thermal margin for applications with elevated ambient temperatures or higher current stress. Active production status ensures long-term availability. Suitable for applications where additional power dissipation capability is beneficial without circuit redesign.

RL73H3AR15FTDF (TE Connectivity Passive Product) Direct 1W equivalent with active production status. Maintains all electrical parameters of the original part with extended operating temperature range (-55°C ~ 155°C). Suitable for direct replacement in existing designs.

RL73H3AR15FTE (TE Connectivity Passive Product) Direct 1W equivalent with active production status. Identical electrical specifications to RL73H3AR15FTDF. Suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can I use a 2W rated resistor (CRM2512-FX-R150ELF) as a direct replacement for the 1W LVC25FR150EV? A: Yes. The 2W part maintains all electrical parameters (resistance, tolerance, temperature coefficient) and package dimensions of the 1W original. The higher power rating provides additional thermal capability without affecting circuit performance.

Q: What is the difference between the TE Connectivity parts RL73H3AR15FTDF and RL73H3AR15FTE? A: Both parts are electrically and mechanically identical 1W equivalents. The difference lies in packaging designation. Both are suitable for direct replacement of the LVC25FR150EV.

Q: Does the YAGEO PT2512FK-070R15L require any design changes for automotive applications? A: No design changes are required. The AEC-Q200 qualification indicates this part meets automotive reliability standards. The ±75ppm/°C temperature coefficient is superior to the original specification, and the extended temperature range (-55°C ~ 155°C) supports automotive operating conditions.

Q: Are all substitute parts available in the same packaging format? A: All substitute parts use the 2512 (6432 Metric) package with identical footprint dimensions. Physical dimensions vary slightly within tolerance, but all are compatible with standard 2512 PCB layouts.

Q: What is the significance of the ±75ppm/°C temperature coefficient in the YAGEO part compared to ±100ppm/°C in other parts? A: The lower temperature coefficient (±75ppm/°C) in the YAGEO PT2512FK-070R15L indicates superior temperature stability. Resistance variation over temperature is reduced, which is beneficial for precision current sensing applications.

Q: Can I mix different substitute parts in the same production run? A: All substitute parts meet ROHS3 compliance and MSL 1 requirements. However, for current sense applications where precision is critical, consistency within a single design is recommended. The YAGEO part offers superior temperature stability, while Bourns and TE Connectivity parts provide equivalent performance to the original specification.
