RMCS1206FT47K5 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT47K5 is a 47.5 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. The part is currently active in production. 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 enhanced performance features such as pulse withstanding capability are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT47K5 is determined by strict equivalence across the following parameters: resistance value (47.5 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 environmental compliance (ROHS3, MSL 1). Parts meeting these core criteria are electrically and mechanically interchangeable. Additional features such as automotive AEC-Q200 certification, moisture resistance, or pulse withstanding capability represent enhanced specifications that do not prevent substitution but indicate suitability for specific application requirements. Parts with differing power ratings, non-compliant RoHS status, or affected REACH status require design review before implementation.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement in existing designs without certification requirements, RMCF1206FT47K5 (Stackpole), RC1206FR-0747K5L (YAGEO), and CR1206-FX-4752ELF (Bourns) are fully equivalent substitutes. All three maintain identical electrical specifications, package dimensions, and ROHS3 compliance.

For automotive applications requiring AEC-Q200 certification, RMCF1206FT47K5, AC1206FR-0747K5L, CRCW120647K5FKEA, and CRCW120647K5FKTA are qualified options. RMCF1206FT47K5 and CRCW120647K5FKEA are preferred for new designs due to active product status and full ROHS3 compliance.

CRCW120647K5FKEAHP provides enhanced pulse withstanding capability with 0.75W power rating while maintaining the 1206 package. This part is suitable for applications requiring higher transient energy absorption but requires circuit validation to confirm compatibility with the 0.75W rating.

ERJ-8ENF4752V carries "Not For New Designs" status and should be avoided in new development despite AEC-Q200 qualification and ROHS3 compliance.

CRCW120647K5FKTA is RoHS non-compliant and REACH affected, making it unsuitable for applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can CRCW120647K5FKEAHP (0.75W) be used as a direct substitute for RMCS1206FT47K5 (0.25W)?

A: CRCW120647K5FKEAHP is electrically compatible and maintains identical resistance, tolerance, and package specifications. The higher power rating (0.75W vs 0.25W) does not prevent physical installation. However, circuit design review is required to confirm that the application does not depend on the specific thermal characteristics or power dissipation profile of the 0.25W rating.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection (RMCS1206FT47K5) addresses corrosion from sulfur-containing environments. Moisture-resistant formulations (RC1206FR-0747K5L, AC1206FR-0747K5L, CR1206-FX-4752ELF) provide enhanced protection against humidity and condensation. Both are compatible substitutes; selection depends on the specific environmental exposure of the application.

Q: Are AEC-Q200 certified parts required for non-automotive applications?

A: AEC-Q200 certification is not required for non-automotive use. Standard ROHS3 compliant parts such as RMCF1206FT47K5 or RC1206FR-0747K5L are suitable. AEC-Q200 parts may be used in non-automotive applications without penalty, but the certification cost is unnecessary unless automotive qualification is a future requirement.

Q: Why is CRCW120647K5FKTA listed as a substitute if it is RoHS non-compliant?

A: CRCW120647K5FKTA is electrically and mechanically equivalent but carries RoHS non-compliance and REACH affected status. It is included in the substitute list for reference in legacy system maintenance or applications where environmental compliance is not mandated. New designs must avoid this part.

Q: Can I use ERJ-8ENF4752V in a new design?

A: ERJ-8ENF4752V is marked "Not For New Designs" by the manufacturer. While electrically equivalent and ROHS3 compliant, this status indicates the manufacturer is discontinuing or has discontinued active support. New designs should select from active status alternatives such as RMCF1206FT47K5, CRCW120647K5FKEA, or RC1206FR-0747K5L.

Q: Are all listed substitutes available in the same packaging format?

A: All substitutes are supplied in Tape & Reel (TR) packaging, matching the RMCS1206FT47K5 format. Package dimensions vary slightly between manufacturers (height ranges from 0.024" to 0.030" seated maximum), but all conform to the 1206 (3216 Metric) standard and are compatible with standard pick-and-place equipment.
