CSR2512C0R01F Equivalent & Substitute Parts

Part Overview

The CSR2512C0R01F is a 10 mOhms ±1% 3W chip resistor in 2512 (6432 Metric) package manufactured by Riedon. This current sense, non-inductive metal element resistor is designed for precision applications requiring low resistance values with tight tolerance specifications. The part is currently listed as obsolete, making identification of active equivalent alternatives essential for ongoing production and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSR2512C0R01F is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Package type: 2512 (6432 Metric)
• Composition: Metal Element
• Features: Current Sense, Non-Inductive
• Operating temperature range: -55°C ~ 170°C
• Compliance certifications: ROHS3, REACH Unaffected

The identified substitutes (CSRL3-0R01F2 and CSRL3-0R01F8) are both manufactured by Riedon and maintain full electrical and mechanical equivalence to the original part. Both substitutes are active products with significantly higher inventory availability compared to the obsolete CSR2512C0R01F.

Parameter Comparison

Engineering Selection Recommendations

Both CSRL3-0R01F2 and CSRL3-0R01F8 are direct functional equivalents to the obsolete CSR2512C0R01F. Selection between the two substitutes should be based on the following criteria:

CSRL3-0R01F8 is the preferred substitute when temperature coefficient specification is a design requirement, as it explicitly provides ±75ppm/°C matching the original part's thermal performance characteristics.

CSRL3-0R01F2 is suitable for applications where temperature coefficient is not specified as a critical parameter, offering equivalent electrical performance across all other defined parameters.

Both substitutes maintain full compliance with ROHS3 and REACH requirements. Packaging format differs from the original (Tape & Reel versus Cut Tape & Digi-Reel), which may impact procurement workflows but does not affect component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Can CSRL3-0R01F2 and CSRL3-0R01F8 be used interchangeably with CSR2512C0R01F?

A: Both parts are electrically and mechanically equivalent across all critical parameters including resistance, tolerance, power rating, package dimensions, and operating temperature range. They are direct substitutes for the obsolete CSR2512C0R01F.

Q: What is the difference between CSRL3-0R01F2 and CSRL3-0R01F8?

A: The primary difference is the temperature coefficient specification. CSRL3-0R01F8 specifies ±75ppm/°C, matching the original part. CSRL3-0R01F2 does not provide a temperature coefficient specification. Both maintain identical electrical performance and package specifications.

Q: Are there packaging considerations when switching from CSR2512C0R01F to the CSRL substitutes?

A: The original part is supplied in Cut Tape (CT) & Digi-Reel format, while both substitutes are supplied in Tape & Reel (TR) format. This affects procurement and handling procedures but does not impact component performance or PCB assembly compatibility.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both CSRL3-0R01F2 and CSRL3-0R01F8 are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications as the original part.

Q: What are the physical dimension differences between the original and substitute parts?

A: The original CSR2512C0R01F measures 0.250" L x 0.118" W (6.35mm x 3.00mm). Both substitutes measure 0.252" L x 0.126" W (6.40mm x 3.20mm). Height remains constant at 0.035" (0.90mm) for all three parts. These minor dimensional variations are within standard 2512 package tolerances and do not affect PCB layout or assembly compatibility.
