RMCS1206FT82K5 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT82K5 is an 82.5 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. 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 offer equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT82K5 is determined by strict equivalence across the following parameters:

Resistance value: 82.5 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Termination count: 2
RoHS3 compliance
MSL rating: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) and feature enhancements (automotive AEC-Q200 certification, moisture resistance) do not affect functional substitutability within the specified parameter envelope.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

RMCF1206FT82K5, CR1206-FX-8252ELF, CRCW120682K5FKEA, and RC1206FR-0782K5L are all active production parts suitable for new designs. Selection among these should be based on design-specific requirements:

RMCF1206FT82K5 (Stackpole) provides automotive AEC-Q200 certification from the original manufacturer, maintaining design continuity.
CRCW120682K5FKEA (Vishay Dale) offers automotive AEC-Q200 qualification with the lowest maximum seated height (0.024").
CR1206-FX-8252ELF (Bourns) and RC1206FR-0782K5L (YAGEO) provide moisture-resistant thick film construction for enhanced environmental performance.

Secondary Substitute (Legacy Status):

ERJ-8ENF8252V (Panasonic) carries "Not For New Designs" status and should be used only when existing inventory constraints or design legacy requirements mandate its use. This part remains electrically and mechanically equivalent but is not recommended for new product development.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT82K5 directly replace RMCS1206FT82K5 in existing designs?

A: Yes. Both parts share identical electrical specifications (82.5 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and 1206 package. The primary difference is RMCF1206FT82K5 includes automotive AEC-Q200 certification. Physical dimensions vary slightly (RMCF: 3.20mm x 1.60mm vs. RMCS: 3.10mm x 1.55mm), but both conform to 1206 package standards and are PCB-compatible.

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

A: Anti-sulfur protection (RMCS1206FT82K5) addresses corrosion from sulfur-containing environments. Moisture-resistant construction (CR1206-FX-8252ELF, RC1206FR-0782K5L) enhances performance in high-humidity conditions. Both are thick film resistors with MSL rating 1 (unlimited moisture sensitivity). Feature selection depends on application environment.

Q: Why is ERJ-8ENF8252V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has transitioned this part to legacy status. While electrically and mechanically equivalent, it should not be selected for new product development. Use active alternatives instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts, including the main part RMCS1206FT82K5, carry RoHS3 compliance certification and are suitable for applications requiring RoHS compliance.

Q: Do physical dimension variations affect PCB layout compatibility?

A: All parts conform to 1206 (3216 Metric) package specifications. Variations in seated height (0.024" to 0.030") and length/width (3.10mm to 3.20mm) remain within standard 1206 tolerances and do not require PCB redesign. Verify footprint clearances for height-sensitive applications.
