RMCS1206FT332R Equivalent & Substitute Parts

Part Overview

The RMCS1206FT332R is a 332 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur variant is designed for general industrial applications with unlimited moisture sensitivity rating. Substitute parts are necessary when the primary part is unavailable, 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 RMCS1206FT332R is determined by the following critical parameters:

• Electrical Parameters: Resistance value (332 Ohms), tolerance (±1%), and temperature coefficient (±100ppm/°C) must match exactly
• Power Rating: Substitute parts rated at 0.25W (1/4W) are direct equivalents; parts rated at 0.75W (3/4W) provide enhanced capability
• Package Compatibility: All substitutes must use 1206 (3216 Metric) package with 2 terminations
• Environmental Specifications: Operating temperature range (-55°C ~ 155°C) and MSL rating (1 - Unlimited) must be maintained
• Compliance Requirements: RoHS3 compliance and REACH status determine suitability for regulated applications
• Certifications: AEC-Q200 automotive qualification is an optional enhancement feature

Substitute parts are grouped into two categories: direct equivalents with identical specifications and enhanced variants with additional certifications or performance features.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant)

RMCF1206FT332R, CRCW1206332RFKEA, and AC1206FR-07332RL are recommended as primary substitutes. All three maintain identical electrical specifications, active product status, and full RoHS3 compliance. RMCF1206FT332R from the same manufacturer (Stackpole) provides the closest functional match with AEC-Q200 automotive qualification. CRCW1206332RFKEA from Vishay Dale and AC1206FR-07332RL from YAGEO offer AEC-Q200 certification with moisture-resistant features, suitable for applications requiring automotive-grade reliability.

Enhanced Performance Substitute

CRCW1206332RFKEAHP provides 0.75W power rating with pulse withstanding capability while maintaining AEC-Q200 certification and RoHS3 compliance. This variant is suitable for applications requiring higher transient energy absorption.

Moisture-Resistant Alternatives

CR1206-FX-3320ELF from Bourns and RC1206FR-07332RL from YAGEO offer moisture-resistant thick film construction without automotive certification. These are suitable for general industrial applications where enhanced moisture protection is beneficial.

Restricted Substitutes

CRCW1206332RFKTA is RoHS non-compliant and REACH-affected; use only in applications where regulatory exemptions apply. ERJ-8ENF3320V carries "Not For New Designs" status; use only for legacy system maintenance or repair.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206332RFKEAHP (0.75W) be used as a direct replacement for RMCS1206FT332R (0.25W)?

A: Yes. The 0.75W variant provides enhanced power dissipation capability while maintaining identical electrical parameters (332 Ohms, ±1%, ±100ppm/°C) and package dimensions (1206). Higher power rating does not degrade performance in 0.25W applications; it provides additional thermal margin.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 variants?

A: AEC-Q200 certification indicates automotive-grade qualification with defined reliability and performance standards. Non-certified variants (RMCS1206FT332R, CR1206-FX-3320ELF, RC1206FR-07332RL) are suitable for general industrial use. AEC-Q200 variants are required for automotive applications.

Q: Are moisture-resistant variants necessary for all applications?

A: Moisture-resistant features (AC1206FR-07332RL, CR1206-FX-3320ELF, RC1206FR-07332RL) provide enhanced protection in high-humidity or corrosive environments. Standard variants (RMCS1206FT332R, RMCF1206FT332R) with MSL 1 rating are suitable for controlled manufacturing and storage conditions.

Q: Why is CRCW1206332RFKTA marked as RoHS non-compliant?

A: CRCW1206332RFKTA does not meet RoHS3 requirements and is REACH-affected. This variant is restricted to applications with regulatory exemptions or legacy system maintenance. For new designs, use ROHS3-compliant alternatives.

Q: Can ERJ-8ENF3320V be used in new designs?

A: ERJ-8ENF3320V carries "Not For New Designs" status from Panasonic. While electrically equivalent and AEC-Q200 certified, this part is intended for legacy system support only. Use active-status alternatives for new designs.

Q: What packaging formats are available?

A: RMCS1206FT332R, RMCF1206FT332R, AC1206FR-07332RL, CRCW1206332RFKEA, CRCW1206332RFKEAHP, and ERJ-8ENF3320V are supplied in Tape & Reel (TR) format. CR1206-FX-3320ELF and CRCW1206332RFKTA are supplied in Cut Tape (CT) & Digi-Reel format. RC1206FR-07332RL is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements.
