CRL2512-FV-R030ELF Equivalent & Substitute Parts

Part Overview

The CRL2512-FV-R030ELF is a 30 mOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Bourns Inc. This thick film current sense resistor is designed for precision applications requiring low resistance values with tight tolerance specifications. The part is currently obsolete, making identification of suitable substitute components essential for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRL2512-FV-R030ELF is determined by the following critical parameters:

• Resistance Value: 30 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package Type: 2512 (6432 Metric) (exact match required)
• Number of Terminations: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

The CRF2512-FZ-R030ELF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the substitute features different composition (Metal Element vs. Thick Film), enhanced temperature coefficient performance, and extended operating temperature range, these represent improvements over the original specification and do not preclude substitution.

Engineering Selection Recommendations

The CRF2512-FZ-R030ELF is the qualified substitute for the obsolete CRL2512-FV-R030ELF. Selection of this substitute is supported by:

• Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility.
• Active Product Status: The substitute is currently in active production with substantial inventory availability (23,561 pcs), ensuring supply chain continuity.
• Electrical Equivalence: Identical resistance, tolerance, power rating, and termination configuration guarantee functional compatibility in existing circuit designs.
• Package Compatibility: Identical 2512 (6432 Metric) package dimensions and footprint enable direct board-level substitution without layout modifications.
• Performance Enhancement: The metal element composition and superior temperature coefficient (±50ppm/°C vs. ±400ppm/°C) provide improved stability across the extended operating temperature range (-55°C ~ 170°C).

Frequently Asked Questions (FAQ)

Q: Can the CRF2512-FZ-R030ELF be used as a direct replacement for the CRL2512-FV-R030ELF?

A: Yes. Both parts share identical electrical specifications (30 mOhms, ±1%, 1W), package configuration (2512), and termination count (2). The substitute meets or exceeds all critical parameters required for functional equivalence.

Q: What are the physical dimension differences between these parts?

A: The CRL2512-FV-R030ELF measures 0.248" L × 0.122" W (6.30mm × 3.10mm) with 0.028" maximum seated height. The CRF2512-FZ-R030ELF measures 0.252" L × 0.126" W (6.40mm × 3.20mm) with 0.031" maximum seated height. Both dimensions fall within standard 2512 package tolerances and are compatible with existing PCB footprints.

Q: Why does the substitute have a lower temperature coefficient?

A: The CRF2512-FZ-R030ELF uses metal element composition, which inherently provides superior temperature stability (±50ppm/°C) compared to the thick film construction of the original part (±400ppm/°C). This represents a performance improvement for applications requiring enhanced thermal stability.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings. The substitute includes AEC-Q200 automotive qualification and moisture-resistant features, which represent additional certifications beyond the original specification.

Q: What is the inventory status of the substitute part?

A: The CRF2512-FZ-R030ELF is in active production with 23,561 pcs currently in stock, ensuring reliable availability for production and replacement requirements.
