CSRF2512JT22L0 Equivalent & Substitute Parts

Part Overview

The CSRF2512JT22L0 is a 22 mOhms ±5% 2W chip resistor manufactured by Stackpole Electronics Inc in the 2512 (6432 Metric) package. This metal foil current sense resistor is designed for automotive applications and meets AEC-Q200 qualification standards. The part is actively produced and maintained in inventory, making it suitable for new designs and production applications requiring precision current sensing in automotive environments.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different manufacturers while meeting the same functional requirements and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRF2512JT22L0 is determined by the following critical parameters:

• Resistance value: 22 mOhms (exact match required)
• Power rating: 2W (exact match required)
• Package type: 2512 (6432 Metric) (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C to 170°C (exact match or better required)
• Automotive compliance: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 Compliant (required for regulatory compliance)

The PE2512FKE7W0R022L qualifies as a substitute because it maintains all critical electrical parameters, operates within the same temperature range, carries AEC-Q200 automotive qualification, and meets ROHS3 compliance requirements. The tolerance specification differs (±1% versus ±5%), representing an upgrade in precision rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF2512JT22L0 and PE2512FKE7W0R022L are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

Stackpole CSRF2512JT22L0 is appropriate when the ±5% tolerance specification is acceptable for the application and metal foil composition is preferred for specific thermal or noise characteristics.

YAGEO PE2512FKE7W0R022L is appropriate when tighter tolerance control (±1%) is required for precision current sensing applications, or when metal film composition is specified. This part offers improved tolerance performance while maintaining identical electrical and thermal characteristics.

Both parts are suitable for direct substitution in automotive current sense applications operating within the -55°C to 170°C temperature range. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility and represent only procurement and handling variations.

Frequently Asked Questions (FAQ)

Q: Can PE2512FKE7W0R022L replace CSRF2512JT22L0 in existing designs?

A: Yes. Both parts share identical resistance values, power ratings, package dimensions, temperature coefficients, and operating temperature ranges. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. The PE2512FKE7W0R022L offers improved tolerance (±1% versus ±5%), making it functionally compatible and electrically superior for precision applications.

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

A: Both compositions are provided in the specifications. Metal foil (CSRF2512JT22L0) and metal film (PE2512FKE7W0R022L) are distinct resistor technologies. Selection between them depends on application-specific requirements for noise, temperature stability, or frequency response characteristics not specified in this comparison.

Q: Are the physical dimensions identical?

A: Both parts use the 2512 (6432 Metric) package. Slight dimensional variations exist: CSRF2512JT22L0 measures 0.254" L × 0.128" W (6.45mm × 3.25mm) with 0.037" max height, while PE2512FKE7W0R022L measures 0.250" L × 0.125" W (6.35mm × 3.18mm) with 0.035" max height. These variations remain within standard 2512 package tolerances and do not affect PCB layout compatibility.

Q: What packaging options are available?

A: CSRF2512JT22L0 is supplied in Tape & Reel (TR) format. PE2512FKE7W0R022L is supplied in Cut Tape (CT) and Digi-Reel® format. Both packaging formats are standard for surface mount components and do not affect electrical performance or mechanical fit.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both CSRF2512JT22L0 and PE2512FKE7W0R022L carry AEC-Q200 automotive qualification and ROHS3 compliance certification, meeting automotive industry standards for reliability and environmental compliance.
