Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRF2512FT20L0 is determined by the following critical parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package designation: 2512 (6432 Metric)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The PE2512FKE7W0R02L from YAGEO meets all electrical and mechanical substitution criteria. While the main part uses metal foil composition and the substitute uses metal film composition, both maintain identical electrical performance specifications, dimensional compatibility within the 2512 package class, and equivalent automotive qualification standards.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF2512FT20L0 and PE2512FKE7W0R02L are active production parts with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts should be based on:

• Packaging availability: The main part is supplied in Tape & Reel format, while the substitute is available in Cut Tape and Digi-Reel formats
• Inventory requirements: YAGEO PE2512FKE7W0R02L has higher stock availability (9520 units) compared to the Stackpole part (798 units)
• Dimensional tolerance: Both parts fit within the 2512 package class with minor dimensional variations that remain within standard PCB footprint tolerances
• Supply chain continuity: Either part maintains equivalent electrical performance and automotive compliance for current sense applications

Frequently Asked Questions (FAQ)

Q: Can PE2512FKE7W0R02L replace CSRF2512FT20L0 in automotive applications?

A: Yes. Both parts meet AEC-Q200 qualification, maintain identical electrical specifications (20 mOhms ±1%, 2W, ±50ppm/°C), and operate across the same temperature range (-55°C ~ 170°C). The dimensional differences between metal foil and metal film compositions remain within standard PCB footprint tolerances for the 2512 package class.

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

A: Both compositions are specified in the provided data. The electrical performance parameters—resistance value, tolerance, temperature coefficient, and power rating—are identical between the two parts, making them functionally equivalent for the specified application.

Q: Are there packaging compatibility considerations?

A: The main part is supplied in Tape & Reel format, while the substitute is available in Cut Tape and Digi-Reel formats. Verify that your assembly process accommodates the substitute's packaging format before implementation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CSRF2512FT20L0 and PE2512FKE7W0R02L are ROHS3 compliant, AEC-Q200 qualified, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What are the dimensional differences?

A: The CSRF2512FT20L0 measures 0.254" L x 0.128" W (6.45mm x 3.25mm) with 0.037" max height. The PE2512FKE7W0R02L measures 0.250" L x 0.125" W (6.35mm x 3.18mm) with 0.035" max height. Both fit within the 2512 (6432 Metric) package class and are compatible with standard PCB footprints for this package designation.
