Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4751CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.75 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
• Termination count: 2

Acceptable Variation Parameters:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. Cut Tape)
• Physical height when seated (within component tolerance)
• Specific feature enhancements (e.g., AEC-Q200 automotive qualification, pulse withstanding capability)

All identified substitute parts maintain identical electrical specifications and mechanical compatibility with the RCS2012F4751CS within the 0805 package envelope.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications):

The following parts are direct substitutes with matching 0.125W power rating and ROHS3 compliance:

• AC0805FR-074K75L (YAGEO)
• CRCW08054K75FKEA (Vishay Dale)
• ERJ-6ENF4751V (Panasonic Electronic Components)
• RC0805FR-074K75L (YAGEO)
• RC0805FR-074K75P (YAGEO)
• RMCF0805FT4K75 (Stackpole Electronics Inc)

Higher Power Rating Alternative:

CRCW08054K75FKEAHP (Vishay Dale) provides 0.5W (1/2W) power rating in the same 0805 package with pulse withstanding capability. This part is suitable for applications requiring higher power dissipation margin while maintaining identical resistance and tolerance specifications.

Compliance Consideration:

CRCW08054K75FKTA (Vishay Dale) is RoHS non-compliant and REACH affected. Selection of this part is restricted to applications where RoHS3 compliance is not required.

Packaging Format:

RC0805FR-074K75L is supplied in Cut Tape & Digi-Reel format, differing from standard Tape & Reel packaging. This option is suitable for applications with lower volume requirements or specific handling procedures.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054K75FKEAHP (0.5W) be used as a direct replacement for RCS2012F4751CS (0.125W)?

A: CRCW08054K75FKEAHP is electrically and mechanically compatible with RCS2012F4751CS. The higher power rating (0.5W vs. 0.125W) provides additional thermal margin and does not create incompatibility. The component occupies the same 0805 package footprint with compatible termination specifications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape & Digi-Reel packaging provides components on cut tape segments or alternative reel formats, typically for lower-volume applications or manual assembly. Electrical and mechanical specifications remain identical.

Q: Are all substitute parts AEC-Q200 qualified?

A: AC0805FR-074K75L, CRCW08054K75FKEA, CRCW08054K75FKEAHP, CRCW08054K75FKTA, ERJ-6ENF4751V, and RMCF0805FT4K75 carry AEC-Q200 automotive qualification. RC0805FR-074K75L, RC0805FR-074K75P, and RCS2012F4751CS do not list AEC-Q200 certification. Selection depends on automotive application requirements.

Q: Why is CRCW08054K75FKTA marked as RoHS non-compliant?

A: CRCW08054K75FKTA is designated RoHS non-compliant and REACH affected. This part must not be used in applications subject to RoHS3 regulatory requirements. All other substitute parts maintain ROHS3 compliance.

Q: Do all parts have identical moisture sensitivity levels?

A: All listed parts, including RCS2012F4751CS and all substitutes, carry MSL 1 (Unlimited) moisture sensitivity rating. No special moisture control measures are required during storage or handling.

Q: What is the maximum height variation among substitute parts?

A: Seated height varies from 0.50mm (Vishay Dale CRCW series) to 0.70mm (Panasonic ERJ-6ENF4751V). The RCS2012F4751CS reference part measures 0.66mm maximum. All variations remain within standard 0805 package tolerance and do not affect PCB assembly compatibility.
