CSR2512C0R002F Equivalent & Substitute Parts

Part Overview

The CSR2512C0R002F is a 2 mOhms ±1% 3W chip resistor in 2512 (6432 Metric) package manufactured by Riedon. This current sense, non-inductive metal element resistor operates across -55°C to 170°C and is ROHS3 compliant. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the CSR2512C0R002F is determined by the following critical parameters: resistance value (2 mOhms), tolerance (±1%), package type (2512), composition (metal element), and current sense application. The substitute parts are grouped into two categories:

Direct Equivalents (Same Electrical Specifications): Parts maintaining identical resistance, tolerance, power rating, and operating temperature range. These parts differ only in manufacturer, series designation, or packaging format (Cut Tape vs. Tape & Reel).

Upgrade Substitutes (Enhanced Power Rating): Parts with identical electrical characteristics but higher power dissipation capability (5W vs. 3W). These parts include automotive AEC-Q200 qualification, providing enhanced reliability for demanding applications while maintaining full backward compatibility in 2512 package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): Select CSRL3-0R002F1 or CSRL3-0R002F8 when the original 3W power rating is sufficient and active product availability is required. Both parts maintain identical electrical performance and thermal characteristics. CSRL3-0R002F8 in Tape & Reel format provides higher inventory availability (20,975 pcs) compared to CSRL3-0R002F1.

For Enhanced Reliability Applications: Select CSS2H-2512K-2L00F or CSS2H-2512K-2L00FE when automotive-grade qualification and higher power dissipation margin are beneficial. The 5W rating provides additional thermal headroom while maintaining identical resistance, tolerance, and operating temperature range. CSS2H-2512K-2L00FE in Tape & Reel format is available for automated assembly processes.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical package footprint compatibility with the original CSR2512C0R002F.

Frequently Asked Questions (FAQ)

Q: Can CSRL3-0R002F1 and CSRL3-0R002F8 be used interchangeably with CSR2512C0R002F?

A: Yes. Both parts are direct electrical equivalents with identical resistance (2 mOhms), tolerance (±1%), power rating (3W), and operating temperature range (-55°C to 170°C). The difference is packaging format: CSRL3-0R002F1 uses unspecified packaging while CSRL3-0R002F8 uses Tape & Reel format. Both are pin-compatible and footprint-compatible in 2512 package applications.

Q: What is the difference between the 3W Riedon parts and the 5W Bourns parts?

A: The CSS2H-2512K-2L00F and CSS2H-2512K-2L00FE maintain identical electrical specifications (2 mOhms, ±1%, -55°C to 170°C) but provide 5W power rating versus 3W. The Bourns parts include automotive AEC-Q200 qualification. These are upgrade substitutes offering enhanced thermal performance and automotive-grade reliability while maintaining full backward compatibility.

Q: Are there physical dimension differences between substitute parts?

A: Minor dimensional variations exist. The main part CSR2512C0R002F measures 0.250" L x 0.118" W (6.35mm x 3.00mm) with 0.022" max height. CSRL3 equivalents measure 0.250" L x 0.125" W (6.35mm x 3.18mm) with 0.022" max height. CSS2H upgrades measure 0.250" L x 0.120" W (6.35mm x 3.05mm) with 0.052" max height. All parts fit the 2512 (6432 Metric) package specification and are PCB-compatible.

Q: Which substitute part should be selected for new designs?

A: For new designs, select from active product status parts: CSRL3-0R002F1, CSRL3-0R002F8, CSS2H-2512K-2L00F, or CSS2H-2512K-2L00FE. All maintain long-term availability. For automotive applications or designs requiring enhanced thermal margin, the CSS2H series with AEC-Q200 qualification is preferred.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original CSR2512C0R002F specifications.
