RMCS1206FT7K87 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT7K87 is a 7.87 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur thick film resistor is designed for general-purpose applications requiring precision resistance values with extended operating temperature range from -55°C to 155°C. The part is currently active in production and ROHS3 compliant. Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements mandate specific manufacturer certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT7K87 is determined by strict equivalence across the following critical parameters:

• Resistance value: 7.87 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
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) and specific feature sets (anti-sulfur, moisture resistant, automotive AEC-Q200) do not affect functional substitutability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the RMCS1206FT7K87 based on core electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

CR1206-FX-7871ELF (Bourns Inc.) - Active product status with moisture resistant feature. Suitable for general applications requiring standard thick film performance.

CRCW12067K87FKEA (Vishay Dale) - Active product status with automotive AEC-Q200 certification. Recommended for automotive and mission-critical applications requiring qualified component traceability.

ERJ-8ENF7871V (Panasonic Electronic Components) - Automotive AEC-Q200 certified but marked as "Not For New Designs." This part remains available in inventory but should not be selected for new product development.

RC1206FR-077K87L (YAGEO) - Active product status with moisture resistant feature. Suitable for general applications with established supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the RMCS1206FT7K87?

A: Yes, all listed parts meet the core electrical and mechanical specifications. Physical dimension variations (length, width, height) are within acceptable tolerances for 1206 package footprints and do not affect circuit functionality or PCB assembly compatibility.

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

A: Both are protective features in thick film resistors. Anti-sulfur protection (RMCS1206FT7K87) and moisture resistant features (CR1206-FX-7871ELF, RC1206FR-077K87L) address different environmental degradation mechanisms. Both provide ROHS3 compliance and MSL 1 rating, making them suitable for standard industrial applications.

Q: Should I use the Panasonic ERJ-8ENF7871V for new designs?

A: No. Although the ERJ-8ENF7871V is electrically and mechanically equivalent, it is marked as "Not For New Designs." Use CR1206-FX-7871ELF, CRCW12067K87FKEA, or RC1206FR-077K87L for new product development.

Q: Which substitute should I select for automotive applications?

A: CRCW12067K87FKEA (Vishay Dale) is the recommended choice for automotive applications, as it carries AEC-Q200 certification and maintains active product status.

Q: Are there any package footprint compatibility concerns?

A: All parts use the 1206 (3216 Metric) package. Minor dimensional variations exist (length: 0.122" to 0.126", height: 0.024" to 0.030"), but these fall within standard PCB design tolerances for 1206 components and do not require footprint modifications.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
