Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRF2512FK15L0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive qualification: AEC-Q200
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Two active substitute parts meet these criteria. The CSRF2512FT15L0 is a direct Stackpole equivalent differing only in packaging format (Tape & Reel vs. bulk). The PE2512FKE7W0R015L from YAGEO is a cross-manufacturer substitute with identical electrical specifications and automotive qualification, though manufactured using metal film composition instead of metal foil.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using CSRF2512FK15L0, the CSRF2512FT15L0 is the primary substitute. Both parts are manufactured by Stackpole Electronics Inc with identical electrical and mechanical specifications. The only difference is packaging format: CSRF2512FT15L0 is supplied in Tape & Reel format, which is standard for automated assembly processes.

The PE2512FKE7W0R015L from YAGEO provides a cross-manufacturer alternative with full electrical and compliance equivalence. While manufactured using metal film composition rather than metal foil, it maintains the same resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring suitability for automotive current sense applications.

Selection between Stackpole and YAGEO alternatives should be based on supply chain availability, cost considerations, and any design-specific requirements related to resistor composition. Both are active products with established inventory levels.

Frequently Asked Questions (FAQ)

Q: Can CSRF2512FT15L0 be used as a direct replacement for CSRF2512FK15L0?

A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications, temperature characteristics, and automotive qualification. The difference is packaging format only: CSRF2512FK15L0 is supplied in bulk, while CSRF2512FT15L0 is supplied in Tape & Reel format.

Q: What is the difference between metal foil and metal film composition in these resistors?

A: Both compositions meet the specified electrical parameters for this application. Metal foil resistors (CSRF2512FK15L0, CSRF2512FT15L0) and metal film resistors (PE2512FKE7W0R015L) deliver identical resistance values, tolerance, temperature coefficient, and power ratings. Selection between them depends on supply availability and design requirements.

Q: Is PE2512FKE7W0R015L suitable for automotive applications?

A: Yes. The PE2512FKE7W0R015L carries AEC-Q200 automotive qualification and ROHS3 compliance, matching the requirements of the original CSRF2512FK15L0. It is suitable for automotive current sense applications.

Q: Why is CSRF2512FK15L0 listed as obsolete?

A: The CSRF2512FK15L0 has been superseded by the CSRF2512FT15L0, which is the active Stackpole equivalent. The CSRF2512FT15L0 offers identical performance with standard Tape & Reel packaging for automated assembly.

Q: Are there any package dimension differences between these parts?

A: All three parts use the 2512 (6432 Metric) package. Minor dimensional variations exist: CSRF2512FK15L0 and CSRF2512FT15L0 measure 0.254" L x 0.128" W (6.45mm x 3.25mm), while PE2512FKE7W0R015L measures 0.250" L x 0.125" W (6.35mm x 3.18mm). Both dimensions are within standard 2512 package specifications and are mechanically compatible.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. All three parts carry MSL 1 rating, meaning they can be stored and handled without special moisture protection measures.
