RMCS1206FT787R Equivalent & Substitute Parts

Part Overview

The RMCS1206FT787R is a 787 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) surface mount package manufactured by Stackpole Electronics Inc. This component is actively produced and widely used in general-purpose applications requiring precision resistive elements with anti-sulfur protection.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT787R is determined by strict equivalence across the following parameters:

• Resistance value: 787 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package designation: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All qualified substitutes maintain these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances and differences in additional features (such as automotive AEC-Q200 qualification or moisture resistance enhancements) do not affect functional interchangeability in applications where the primary part is specified.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts meet the core electrical and mechanical requirements for direct replacement of the RMCS1206FT787R. Selection among qualified alternatives should be based on the following factors:

AC1206FR-07787RL (YAGEO): Active product status with automotive AEC-Q200 qualification and moisture-resistant construction. Suitable for applications requiring enhanced environmental protection and automotive-grade reliability.

CRCW1206787RFKEA (Vishay Dale): Active product status with automotive AEC-Q200 qualification. Established supply chain with high inventory availability. Appropriate for general-purpose and automotive applications.

RC1206FR-07787RL (YAGEO): Active product status with moisture-resistant thick film construction. High inventory availability. Recommended for applications where moisture resistance is beneficial but automotive qualification is not required.

ERJ-8ENF7870V (Panasonic): Marked as "Not For New Designs." While electrically and mechanically equivalent, this part should be avoided in new product development. Existing designs currently using this part may continue to source it from available inventory.

Frequently Asked Questions (FAQ)

Q: Can RMCS1206FT787R be directly replaced with any of these substitute parts?

A: Yes. All substitute parts except ERJ-8ENF7870V are direct replacements. They share identical resistance, tolerance, power rating, package, composition, temperature coefficient, and operating temperature range. ERJ-8ENF7870V is electrically and mechanically equivalent but is not recommended for new designs.

Q: What is the difference between the anti-sulfur feature of RMCS1206FT787R and the moisture-resistant feature of RC1206FR-07787RL?

A: Both features provide environmental protection through different mechanisms. Anti-sulfur protection specifically addresses sulfur contamination in the operating environment. Moisture-resistant construction protects against moisture ingress. Both are protective enhancements that do not affect core electrical performance or interchangeability.

Q: Are the physical dimension variations between substitute parts significant?

A: No. All parts conform to the 1206 (3216 Metric) package standard. Minor variations in length (0.122" to 0.126"), width (0.061" to 0.063"), and height (0.024" to 0.028") fall within standard manufacturing tolerances and do not affect PCB layout compatibility or functional performance.

Q: Which substitute part should be selected for automotive applications?

A: AC1206FR-07787RL and CRCW1206787RFKEA both carry AEC-Q200 automotive qualification. Either part is appropriate for automotive-grade applications. RC1206FR-07787RL lacks automotive certification and should not be used in automotive designs unless the application does not require AEC-Q200 compliance.

Q: Why is ERJ-8ENF7870V marked as "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While existing inventory remains available and the part is functionally equivalent, new product designs should select from actively supported alternatives to ensure long-term supply continuity and manufacturer support.

Q: Are all substitute parts REACH compliant?

A: Yes. All parts listed are REACH Unaffected, indicating compliance with REACH regulations.
