Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Resistance value: 115 Ohms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Power Rating: Parts with equal or higher power rating (0.125W or greater) are acceptable substitutes

All identified substitute parts meet these criteria. Parts are grouped by power rating alignment and manufacturer certifications as provided in the input data.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Equal Power Rating - 0.125W):

CRCW0805115RFKEA, ERJ-6ENF1150V, and RC0805FR-07115RL are direct functional equivalents to RCS2012F1150CS. All three parts share identical electrical specifications, package dimensions, and compliance certifications. Selection among these three is based on manufacturer availability and supply chain requirements.

Higher Power Rating Alternative:

CRCW0805115RFKEAHP provides 0.5W (1/2W) power rating in the same 0805 package. This part is suitable for applications requiring higher power dissipation capability while maintaining all other electrical and mechanical specifications. The increased power rating does not create incompatibility with circuits designed for 0.125W operation.

Compliance Alignment:

All substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original component. Vishay Dale and Panasonic parts include AEC-Q200 automotive qualification, which is an additional certification not present in the original Samsung part or YAGEO part.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805115RFKEAHP (0.5W) be used in place of RCS2012F1150CS (0.125W)?

A: Yes. The higher power rating (0.5W vs 0.125W) in the same 0805 package provides additional thermal margin. The part is electrically and mechanically compatible. Applications designed for 0.125W operation function without modification.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive qualification standard. CRCW0805115RFKEA, CRCW0805115RFKEAHP, and ERJ-6ENF1150V carry this certification. The original RCS2012F1150CS does not list this certification. AEC-Q200 parts meet additional reliability and testing requirements suitable for automotive applications.

Q: Are there physical dimension differences between substitute parts?

A: All parts use 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height varies slightly: Samsung 0.66mm, Vishay 0.50mm, Panasonic 0.70mm, YAGEO 0.60mm. These variations are within standard PCB assembly tolerances and do not affect circuit functionality.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF1150V (Panasonic) shows 83,430 pieces in stock, followed by RC0805FR-07115RL (YAGEO) with 40,836 pieces. CRCW0805115RFKEA (Vishay Dale) has 20,568 pieces, and CRCW0805115RFKEAHP has 4,903 pieces.

Q: Can substitute parts be mixed in the same circuit board assembly?

A: Yes. All substitute parts meet identical electrical specifications and package requirements. Mixed sourcing from multiple manufacturers is permissible from an engineering standpoint, though manufacturing and quality control procedures may impose restrictions.

Q: What is the difference between RCS2012F1150CS and RC0805FR-07115RL?

A: Both parts are 115 Ohm ±1% 0.125W 0805 thick film resistors with identical electrical performance. The primary difference is manufacturer: Samsung versus YAGEO. RC0805FR-07115RL lists moisture-resistant features similar to the original part. No functional difference exists for circuit applications.
