CSR2512C0R075F Equivalent & Substitute Parts

Part Overview

The CSR2512C0R075F is a 75 milliohm, ±1% tolerance, 3-watt chip resistor in the 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 classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSR2512C0R075F are qualified based on the following critical parameters:

• Resistance value: 75 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 3W (exact match required)
• Package: 2512 (6432 metric) (exact match required)
• Composition: Metal Element (exact match required)
• Features: Current Sense, Non-Inductive (exact match required)
• Operating temperature range: -55°C to 170°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Both substitute parts meet all critical electrical and mechanical parameters. The primary distinction between substitutes is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete CSR2512C0R075F, both CSRL3-0R075F1 and CSRL3-0R075F8 are direct functional equivalents. Both substitute parts are manufactured by Riedon and maintain active product status, ensuring long-term availability and supply chain continuity.

CSRL3-0R075F1 is suitable for standard procurement channels and applications requiring individual component packaging. CSRL3-0R075F8, supplied in Tape & Reel format, is optimized for high-volume automated assembly processes and offers greater inventory availability (3244 pieces in stock versus 1120 pieces for CSRL3-0R075F1).

Both substitutes maintain full ROHS3 compliance and identical electrical performance specifications. Dimensional variations between the original part and substitutes are minimal and fall within standard PCB layout tolerances for 2512 package components.

Frequently Asked Questions (FAQ)

Q: Are CSRL3-0R075F1 and CSRL3-0R075F8 electrically identical to CSR2512C0R075F?

A: Yes. Both substitute parts match the original part in resistance value (75 mOhms), tolerance (±1%), power rating (3W), composition (metal element), and operating temperature range (-55°C to 170°C). All three parts are ROHS3 compliant with MSL rating of 1.

Q: What is the difference between CSRL3-0R075F1 and CSRL3-0R075F8?

A: The primary difference is packaging format. CSRL3-0R075F1 is supplied in standard packaging, while CSRL3-0R075F8 is supplied in Tape & Reel (TR) format for automated assembly. Electrical specifications are identical.

Q: Will the substitute parts fit the same PCB footprint as the original CSR2512C0R075F?

A: Yes. All three parts use the 2512 (6432 metric) package. Minor dimensional variations (approximately 0.002" in length and width) are within standard PCB design tolerances for this package class and do not affect mechanical fit or electrical performance.

Q: Why is the original CSR2512C0R075F marked as obsolete?

A: The CSR2512C0R075F has been discontinued by Riedon. The CSRL series represents the current active product line for equivalent 75 milliohm, 3-watt, 2512 package current sense resistors.

Q: Are there any compliance or certification differences between the original and substitute parts?

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (unlimited moisture sensitivity level).
