Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FTR430 is determined by the following critical parameters:

• Resistance value: 430 mOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package type: 1206 (3216 Metric)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thick film
• RoHS compliance: ROHS3 Compliant

The RCWE1206R430FKEA from Vishay Dale meets all these parameters and qualifies as a direct substitute. Both parts share identical electrical specifications, package dimensions within tolerance, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FTR430 and RCWE1206R430FKEA are active production parts with ROHS3 compliance and identical electrical and thermal specifications. The RCWE1206R430FKEA includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Selection between these parts should be based on supply chain availability, lead time requirements, and whether automotive qualification is mandated by application specifications.

Frequently Asked Questions (FAQ)

Q: Can RCWE1206R430FKEA replace CSR1206FTR430 in all applications?

A: Yes. Both parts share identical resistance, tolerance, power rating, package, temperature coefficient, and operating temperature range. The RCWE1206R430FKEA includes AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts use the 1206 (3216 Metric) package with equivalent footprints. Dimensional variations (CSR: 3.05mm × 1.55mm; RCWE: 3.10mm × 1.60mm) are within standard PCB design tolerances and do not affect assembly or performance.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This specification defines the resistance change per degree Celsius across the operating temperature range. Both parts maintain this specification, ensuring stable current sensing performance across -55°C to 155°C.

Q: Does moisture sensitivity level affect substitution?

A: No. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply equally to both parts.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The RCWE1206R430FKEA carries additional AEC-Q200 automotive qualification, which is a superset qualification not present in the CSR1206FTR430 specification.
