Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3480CS is determined by strict equivalence across the following parameters:

Electrical Equivalence: Resistance value (348 Ohms), tolerance (±1%), and power rating (0.125W) must be identical.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and physical dimensions (0.079" L x 0.049" W) must match to ensure PCB footprint compatibility.

Environmental Performance: Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must be equivalent or superior.

Regulatory Compliance: RoHS3 compliance and MSL rating (1 - Unlimited) must be maintained.

Composition: Thick film construction is required for thermal and frequency response characteristics.

All four substitute parts listed meet these criteria and are classified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are Active product status components with ROHS3 compliance and MSL-1 ratings, confirming regulatory equivalence to the RCS2012F3480CS.

CRCW0805348RFKEA (Vishay Dale): Automotive AEC-Q200 rated. Lowest seated height (0.020" / 0.50mm) provides design flexibility for space-constrained applications. Suitable for automotive and industrial environments.

ERJ-6ENF3480V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Highest seated height (0.028" / 0.70mm). Largest available inventory (244,680 pcs) ensures supply continuity. Appropriate for automotive-grade circuit requirements.

RC0805FR-07348RL (YAGEO): Moisture-resistant construction aligns with the original part's environmental protection features. Mid-range seated height (0.024" / 0.60mm). Suitable for general industrial and consumer applications.

RMCF0805FT348R (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Seated height (0.026" / 0.65mm) matches the original component. Substantial inventory availability (117,515 pcs). Appropriate for automotive and industrial applications.

Selection between substitutes depends on application requirements: automotive-grade designs benefit from AEC-Q200 rated options; space-constrained designs favor lower-profile components; supply chain considerations may prioritize highest-inventory options.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805348RFKEA replace RCS2012F3480CS in all applications?

A: Yes. Both components share identical electrical specifications (348 Ohms ±1%, 0.125W), package designation (0805), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance ratings (ROHS3, MSL-1). The lower seated height of CRCW0805348RFKEA (0.020" vs 0.026") is mechanically compatible with standard 0805 PCB footprints.

Q: What is the difference between automotive AEC-Q200 rated and non-rated substitutes?

A: CRCW0805348RFKEA, ERJ-6ENF3480V, and RMCF0805FT348R carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. RC0805FR-07348RL does not carry this rating. Selection depends on whether the application requires automotive-grade certification.

Q: Are all substitutes compatible with the same PCB footprint?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049") dimensions. Seated height variations (0.020" to 0.028") fall within standard PCB assembly tolerances and do not affect footprint compatibility.

Q: Which substitute offers the best supply availability?

A: ERJ-6ENF3480V (Panasonic) has the highest inventory at 244,680 pcs, followed by RMCF0805FT348R (Stackpole) at 117,515 pcs. Both provide strong supply continuity for production requirements.

Q: Can RC0805FR-07348RL be used in automotive applications?

A: RC0805FR-07348RL meets all electrical and environmental specifications required for automotive use but does not carry AEC-Q200 certification. Applications requiring formal automotive qualification should use CRCW0805348RFKEA, ERJ-6ENF3480V, or RMCF0805FT348R instead.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. All parts, including the original RCS2012F3480CS and all four substitutes, carry MSL-1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
