Key Parameters

Substitute Part Grouping Explanation

Substitution for the FCSL64R015FER is determined by strict equivalence in the following parameters:

• Resistance value: 15 mOhms
• Tolerance: ±1%
• Package / Case: Wide 2512 (6432 Metric), 1225
• Composition: Metal Foil
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Mechanical dimensions: 0.122" L x 0.248" W (3.10mm x 6.30mm)
• Height - Seated (Max): 0.028" (0.70mm)

The substitute part KRL6432E-M-R015-F-T1 meets all these core parameters. Power rating differences and packaging format variations (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect electrical substitution eligibility when mechanical and electrical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both parts are Active status and meet RoHS compliance requirements. The KRL6432E-M-R015-F-T1 carries AEC-Q200 automotive qualification and REACH Unaffected status, providing additional compliance documentation for applications requiring automotive-grade components. The higher power rating (3W vs. 2W) of the Susumu part does not create incompatibility; it represents a design margin advantage in thermal performance. Selection between these parts depends on supply chain availability, packaging format requirements (Tape & Reel vs. Cut Tape & Digi-Reel), and compliance certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can KRL6432E-M-R015-F-T1 replace FCSL64R015FER in existing designs?

A: Yes. Both parts share identical resistance, tolerance, temperature coefficient, operating temperature range, and mechanical dimensions. The higher power rating of the substitute part does not create electrical or mechanical incompatibility.

Q: Are there differences in packaging that affect PCB assembly?

A: The main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) & Digi-Reel format. Both use the same Wide 2512 (6432 Metric) package footprint. Assembly equipment compatibility depends on your specific reel handling capabilities.

Q: Does the AEC-Q200 rating on the substitute part affect compatibility?

A: No. AEC-Q200 is an additional qualification that does not alter electrical or mechanical performance. It indicates the part meets automotive reliability standards and may be required for certain applications.

Q: What is the significance of the ±50ppm/°C temperature coefficient?

A: This specification defines resistance drift over the operating temperature range. Both parts are identical at ±50ppm/°C, ensuring equivalent stability in temperature-sensitive current sensing circuits.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.122" L x 0.248" W (3.10mm x 6.30mm) with a maximum seated height of 0.028" (0.70mm), ensuring identical PCB footprint compatibility.
