Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRL2512-FW-R430ELF is determined by the following critical parameters:

• Resistance value: 430 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• RoHS3 compliance status
• Moisture sensitivity level: 1

The RMCF2512FTR430 manufactured by Stackpole Electronics Inc. meets all electrical and mechanical substitution criteria. Both components share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both maintain RoHS3 compliance and MSL 1 rating, confirming direct substitutability at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the CRL2512-FW-R430ELF and RMCF2512FTR430 are Active status components with full RoHS3 compliance and identical core electrical specifications. The RMCF2512FTR430 carries AEC-Q200 automotive qualification and supports an extended operating temperature range to 155°C compared to 125°C for the Bourns part. Width dimension variance (0.122" vs 0.126") remains within standard PCB layout tolerances for 2512 package footprints. Selection between these parts depends on application requirements: the Stackpole component is suitable for automotive and extended temperature applications, while the Bourns component addresses standard industrial and commercial requirements.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FTR430 directly replace CRL2512-FW-R430ELF in existing designs?

A: Yes. Both components share identical electrical specifications (430 mOhms ±1%, 1W, ±200ppm/°C) and package footprint (2512). The 0.004" width difference (0.122" vs 0.126") is within standard PCB design tolerances for this package class.

Q: What is the significance of AEC-Q200 qualification on the Stackpole part?

A: AEC-Q200 is an automotive industry standard qualification. The RMCF2512FTR430 meets automotive reliability and performance requirements. This qualification is not required for non-automotive applications but provides additional assurance for automotive and high-reliability environments.

Q: Does the extended temperature range of RMCF2512FTR430 affect substitution eligibility?

A: The extended range (-55°C to 155°C vs -55°C to 125°C) does not prevent substitution. If the application operates within the CRL2512-FW-R430ELF range (-55°C to 125°C), both parts perform identically. The Stackpole part offers additional capability for higher temperature applications.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both CRL2512-FW-R430ELF and RMCF2512FTR430 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
