Substitute Part Grouping Explanation

Substitution for the CSR2512C0R025F is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 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 (CSRL3-0R025F1 and CSRL3-0R025F8) meet all these electrical and mechanical parameters. Both are manufactured by Riedon and maintain Active product status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Both CSRL3-0R025F1 and CSRL3-0R025F8 are direct functional equivalents to the obsolete CSR2512C0R025F. Selection between these two active alternatives depends on packaging requirements and inventory availability:

CSRL3-0R025F1 is suitable for applications requiring standard packaging formats and maintains full electrical and mechanical compatibility with the original part.

CSRL3-0R025F8 is supplied in Tape & Reel (TR) packaging, making it optimal for high-volume automated assembly processes. This variant offers significantly higher inventory availability (8665 Pcs) compared to CSRL3-0R025F1 (803 Pcs).

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with modern manufacturing and environmental standards. The minor dimensional variations (0.252" L x 0.126" W versus 0.250" L x 0.118" W) remain within standard PCB layout tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can CSRL3-0R025F1 and CSRL3-0R025F8 be used interchangeably with CSR2512C0R025F?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance (25 mOhms), tolerance (±1%), power rating (3W), package type (2512), composition (Metal Element), and operating temperature range (-55°C ~ 170°C). The primary difference is packaging format.

Q: What is the difference between CSRL3-0R025F1 and CSRL3-0R025F8?

A: Both parts are electrically identical. CSRL3-0R025F8 is supplied in Tape & Reel (TR) packaging for automated assembly, while CSRL3-0R025F1 uses standard packaging. CSRL3-0R025F8 has higher inventory availability.

Q: Are there dimensional differences between the substitute parts and the original?

A: Minor dimensional variations exist. The original CSR2512C0R025F measures 0.250" L x 0.118" W (6.35mm x 3.00mm), while both CSRL3 variants measure 0.252" L x 0.126" W (6.40mm x 3.20mm). These differences are within standard 2512 package tolerances and do not affect PCB compatibility.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both CSRL3-0R025F1 and CSRL3-0R025F8 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's certifications.

Q: Why is the original CSR2512C0R025F marked as Obsolete?

A: The CSR2512C0R025F has been discontinued by the manufacturer. The CSRL3 series represents the active product line replacement, ensuring continued availability and supply chain support.
