RMCS0805FT511K Equivalent & Substitute Parts

Part Overview

The RMCS0805FT511K is a 511 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This component features anti-sulfur construction and operates across -55°C to 155°C. The part is active in production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when designs require alternative sourcing, inventory optimization, or when the primary part becomes unavailable while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT511K is determined by strict equivalence across the following parameters:

• Resistance value: 511 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in features (anti-sulfur, automotive AEC-Q200, moisture resistant) and physical dimensions (height seated) do not affect functional substitutability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among equivalent parts may be based on:

• Inventory availability and lead times
• Supplier relationships and pricing
• Feature requirements: RMCF0805FT511K, CRCW0805511KFKEA, and ERJ-6ENF5113V include automotive AEC-Q200 qualification for applications requiring automotive-grade reliability; RC0805FR-07511KL provides moisture-resistant construction; RMCS0805FT511K offers anti-sulfur protection
• Physical height constraints: CRCW0805511KFKEA (0.020" max) provides the lowest profile; ERJ-6ENF5113V (0.028" max) the highest

All parts are electrically and mechanically interchangeable within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT511K replace RMCS0805FT511K directly?

A: Yes. Both parts share identical electrical specifications (511 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and 0805 package. The primary difference is RMCF0805FT511K includes automotive AEC-Q200 qualification, making it suitable for automotive applications while remaining compatible with standard industrial designs.

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

A: Anti-sulfur construction (RMCS0805FT511K) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (RC0805FR-07511KL) provides protection against humidity ingress. Both are protective features that do not affect electrical substitutability.

Q: Are all substitute parts suitable for automotive applications?

A: RMCF0805FT511K, CRCW0805511KFKEA, and ERJ-6ENF5113V carry AEC-Q200 automotive qualification. RMCS0805FT511K and RC0805FR-07511KL do not carry this certification. For automotive designs requiring AEC-Q200 compliance, use only the three qualified alternatives.

Q: Does physical height variation affect PCB assembly?

A: Height differences range from 0.020" to 0.028" (0.50mm to 0.70mm). For standard PCB assembly, these variations are within typical component tolerances. Verify height constraints only if designs have specific clearance limitations.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All listed parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
