RMCS1206FT475K Equivalent & Substitute Parts

Part Overview

The RMCS1206FT475K is a 475 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur resistor operates across -55°C to 155°C and is ROHS3 compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, when design requirements mandate specific certifications such as AEC-Q200 automotive qualification, or when alternative manufacturers' components offer improved availability or cost optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT475K is determined by strict equivalence across the following parameters: resistance value (475 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts meet these core electrical and mechanical requirements. Substitutes are grouped by manufacturer and feature differentiation: Stackpole RMCF1206FT475K adds AEC-Q200 automotive qualification; Bourns CR1206-FX-4753ELF and YAGEO RC1206FR-07475KL provide moisture-resistant variants; Vishay Dale CRCW1206475KFKEA and Panasonic ERJ-8ENF4753V offer AEC-Q200 certification. All substitutes maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive-grade components, RMCF1206FT475K (Stackpole), CRCW1206475KFKEA (Vishay Dale), and CRCW1206475KFKEA (Vishay Dale) provide AEC-Q200 certification while maintaining active product status. The ERJ-8ENF4753V, though AEC-Q200 qualified, carries "Not For New Designs" status and should be avoided in new development. For general industrial applications without automotive requirements, CR1206-FX-4753ELF (Bourns) and RC1206FR-07475KL (YAGEO) offer moisture-resistant thick film construction with active product status. The RMCS1206FT475K original part features anti-sulfur composition and remains suitable for non-automotive applications. All substitutes maintain identical electrical performance across the specified temperature range and comply with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT475K replace RMCS1206FT475K in non-automotive applications? A: Yes. Both parts share identical resistance (475 kOhms), tolerance (±1%), power rating (0.25W), package (1206), and temperature specifications (-55°C to 155°C). The RMCF variant adds AEC-Q200 automotive qualification, which does not restrict use in general applications.

Q: What is the difference between anti-sulfur and moisture-resistant features? A: Anti-sulfur composition (RMCS1206FT475K) protects against sulfur contamination in specific environments. Moisture-resistant variants (CR1206-FX-4753ELF, RC1206FR-07475KL) provide protection against moisture ingress. Both are ROHS3 compliant with MSL 1 (unlimited) rating. Feature selection depends on environmental exposure requirements.

Q: Are all substitute parts available in the same package dimensions? A: All parts use 1206 (3216 Metric) package. Minor variations exist in seated height (0.026" to 0.030"), which are within standard PCB assembly tolerances and do not affect interchangeability on standard 1206 footprints.

Q: Why is ERJ-8ENF4753V marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active development for this part number. While electrically equivalent and currently in stock, new designs should prioritize active-status alternatives such as RMCF1206FT475K, CRCW1206475KFKEA, or RC1206FR-07475KL.

Q: Do all substitutes meet the same compliance requirements? A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Automotive-qualified variants (RMCF1206FT475K, CRCW1206475KFKEA, ERJ-8ENF4753V) additionally meet AEC-Q200 standards.
