CSR2512C0R03F Equivalent & Substitute Parts

Part Overview

The CSR2512C0R03F is a 30 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 low-resistance applications requiring high power dissipation. The part is currently listed as obsolete, making identification of active equivalent parts essential for ongoing production and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSR2512C0R03F is determined by strict equivalence across the following critical parameters:

• Resistance value: 30 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
• RoHS compliance: ROHS3 Compliant

The substitute parts identified (CSRL3-0R03F1 and CSRL3-0R03F8) meet all these criteria and are manufactured by the same supplier (Riedon). Both substitute parts are in active product status, providing long-term availability advantages over the obsolete CSR2512C0R03F.

Parameter Comparison

Engineering Selection Recommendations

Both CSRL3-0R03F1 and CSRL3-0R03F8 are direct functional equivalents to the obsolete CSR2512C0R03F. Selection between the two substitute parts should be based on packaging requirements and inventory availability:

CSRL3-0R03F1 is suitable for applications where packaging format is not a constraint, with 838 pieces currently in stock.

CSRL3-0R03F8 is packaged in Tape & Reel (TR) format and offers significantly higher inventory availability with 16,837 pieces in stock, making it the preferred choice for high-volume production requirements.

Both parts maintain full compliance with ROHS3 and REACH regulations. The minor dimensional variations between the original part and substitutes (0.002" length and 0.008" width differences) remain within standard PCB design tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can CSRL3-0R03F1 and CSRL3-0R03F8 be used interchangeably with CSR2512C0R03F?

A: Yes. Both parts meet all electrical and mechanical specifications of the original part, including resistance value, tolerance, power rating, package dimensions, and operating temperature range. The primary difference is product status (active vs. obsolete) and packaging format.

Q: What is the difference between CSRL3-0R03F1 and CSRL3-0R03F8?

A: Both parts are electrically identical with matching resistance, tolerance, power rating, and operating temperature specifications. The primary differences are packaging format (CSRL3-0R03F8 uses Tape & Reel) and inventory availability (CSRL3-0R03F8 has significantly higher stock levels).

Q: Are there dimensional compatibility concerns when substituting these parts?

A: The substitute parts have slightly larger dimensions (0.252" L x 0.126" W vs. 0.250" L x 0.118" W for the original). These differences are within standard PCB design tolerances for 2512 package footprints. Height remains identical at 0.035" maximum.

Q: Do the substitute parts maintain the same temperature coefficient performance?

A: CSRL3-0R03F1 specifies ±50ppm/°C, matching the original part. CSRL3-0R03F8 does not specify temperature coefficient in the provided data. For applications requiring confirmed temperature coefficient performance, CSRL3-0R03F1 is the recommended choice.

Q: What packaging options are available for these substitutes?

A: CSRL3-0R03F8 is available in Tape & Reel (TR) format. CSRL3-0R03F1 packaging format is not specified in the provided data. For specific packaging requirements, verify with the supplier.
