Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4R75CS is determined by strict equivalence across the following mandatory parameters:

Electrical Parameters (Non-Negotiable):

• Resistance value: 4.75 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Non-Negotiable):

• Package / Case: 0805 (2012 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Non-Negotiable):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Manufacturer identity
• Temperature coefficient (within acceptable engineering margins)
• Packaging format (Tape & Reel vs. Cut Tape)
• Specific feature set (e.g., automotive qualification)
• Seated height (within 0805 package specification)

The identified substitute parts RC0805FR-074R75L (YAGEO) and RMCF0805FG4R75 (Stackpole Electronics Inc) meet all mandatory electrical, mechanical, and compliance criteria and are therefore direct substitutes for the RC2012F4R75CS.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-074R75L (YAGEO) is a direct electrical and mechanical equivalent to the RC2012F4R75CS. This substitute maintains identical resistance, tolerance, power rating, and package specifications. The YAGEO part exhibits a lower temperature coefficient (±200ppm/°C versus ±300ppm/°C), which represents improved temperature stability. Both parts are ROHS3 compliant with MSL 1 rating and Active product status. The RC0805FR-074R75L is available in Tape & Reel packaging, matching the original part format. This substitute is suitable for applications where supply continuity from Samsung Electro-Mechanics is constrained.

RMCF0805FG4R75 (Stackpole Electronics Inc) is a direct electrical and mechanical equivalent with additional automotive qualification. This substitute meets all mandatory electrical and compliance specifications and is rated to AEC-Q200 automotive standards. The RMCF part is supplied in Cut Tape format rather than Tape & Reel, which may require alternative handling procedures in automated assembly environments. The temperature coefficient matches the YAGEO substitute at ±200ppm/°C. This substitute is appropriate for automotive applications or where AEC-Q200 qualification is a system requirement.

Both substitutes maintain Active product status and full RoHS3 compliance. Selection between substitutes should be based on packaging format requirements (Tape & Reel versus Cut Tape) and automotive qualification necessity.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074R75L replace RC2012F4R75CS in any application?

A: Yes. The RC0805FR-074R75L meets all mandatory electrical, mechanical, and compliance specifications. Both parts are 4.75 Ohm ±1% thick film resistors in 0805 package with identical power ratings, operating temperature ranges, and RoHS3 compliance. The YAGEO substitute has a lower temperature coefficient (±200ppm/°C), which provides improved stability across temperature variations.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, typically for manual assembly or lower-volume applications. The RC2012F4R75CS and RC0805FR-074R75L are supplied in Tape & Reel format. The RMCF0805FG4R75 is supplied in Cut Tape format and may require different handling in automated manufacturing environments.

Q: Is RMCF0805FG4R75 suitable for non-automotive applications?

A: Yes. The RMCF0805FG4R75 meets all electrical and mechanical specifications required for the RC2012F4R75CS. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive applications. This substitute is appropriate for any application requiring the specified 4.75 Ohm ±1% 0.125W 0805 thick film resistor.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components rated MSL 1 have unlimited shelf life and do not require special moisture-controlled storage or baking procedures before soldering. All three parts (RC2012F4R75CS, RC0805FR-074R75L, and RMCF0805FG4R75) carry MSL 1 rating.

Q: Are there differences in seated height between the substitutes?

A: The RC2012F4R75CS and RMCF0805FG4R75 have identical maximum seated height of 0.026" (0.65mm). The RC0805FR-074R75L has a slightly lower maximum seated height of 0.024" (0.60mm). Both values are within 0805 package specification and do not affect PCB assembly compatibility.

Q: What does ROHS3 Compliant mean?

A: ROHS3 refers to compliance with the Restriction of Hazardous Substances Directive (RoHS 3 / 2015/863/EU). All three parts are ROHS3 compliant, indicating they do not contain restricted substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers above specified thresholds.

Q: Can I mix manufacturers in the same assembly?

A: Yes. All three parts meet identical electrical and mechanical specifications and are ROHS3 compliant with MSL 1 rating. Mixing manufacturers in the same assembly is permissible from an engineering standpoint. However, procurement and quality assurance procedures should be followed according to your organization's component management policies.
