Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F3483CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (348 kOhms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) ensure PCB footprint compatibility. Height variations within seated maximum specifications do not affect substitutability.

Regulatory Compliance: RoHS3 compliance, MSL Level 1, and REACH Unaffected status are maintained across all qualified substitutes.

Composition & Features: Thick film construction is consistent. Moisture resistance is a baseline feature; automotive AEC-Q200 qualification and high voltage capabilities represent enhanced feature sets that do not preclude substitution.

All identified substitutes meet these criteria and are classified as direct or similar equivalents based on feature parity with the main part.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-07348KL (YAGEO): Direct equivalent with identical electrical and thermal specifications. Active product status. Lowest seated height (0.60mm) provides clearance advantage in space-constrained layouts. Suitable for general-purpose applications requiring moisture-resistant thick film construction.

CRCW0805348KFKEA (Vishay Dale): Direct equivalent with automotive AEC-Q200 qualification. Lowest seated height (0.50mm) among all substitutes. Recommended for automotive and industrial applications requiring enhanced reliability standards. ROHS3 compliant.

ERJ-6ENF3483V (Panasonic): Direct equivalent with automotive AEC-Q200 qualification. Highest seated height (0.70mm) among substitutes. Suitable for automotive and industrial applications. ROHS3 compliant.

KTR10EZPF3483 (Rohm Semiconductor): Direct equivalent with automotive AEC-Q200 qualification and high voltage capability. Seated height (0.65mm) within standard range. Recommended for high-voltage circuit applications requiring automotive-grade reliability. ROHS3 compliant.

All substitutes maintain Active product status and ROHS3 compliance. Selection should be based on application requirements, available inventory, and specific feature needs (automotive qualification, high voltage capability).

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07348KL replace RC2012F3483CS directly on the PCB?

A: Yes. Both components share identical electrical specifications (348 kOhms ±1%, 0.125W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), and 0805 package footprint (2.00mm x 1.25mm). The seated height difference (0.60mm vs 0.66mm) does not affect PCB compatibility.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: The RC2012F3483CS features moisture resistance as a baseline characteristic. CRCW0805348KFKEA, ERJ-6ENF3483V, and KTR10EZPF3483 include automotive AEC-Q200 qualification, which specifies enhanced reliability testing and performance standards for automotive applications. Both feature sets are compatible with the same PCB footprint and electrical requirements.

Q: Does the seated height variation affect circuit performance?

A: No. Seated height variations (0.50mm to 0.70mm) do not affect electrical performance or circuit functionality. Height differences are relevant only for PCB assembly clearance and automated placement equipment compatibility. All variants maintain the same 0805 package footprint.

Q: Are all substitutes ROHS3 compliant?

A: Yes. RC0805FR-07348KL, CRCW0805348KFKEA, ERJ-6ENF3483V, and KTR10EZPF3483 are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original RC2012F3483CS specification.

Q: Which substitute should be selected for automotive applications?

A: CRCW0805348KFKEA (Vishay Dale), ERJ-6ENF3483V (Panasonic), and KTR10EZPF3483 (Rohm) all carry automotive AEC-Q200 qualification. KTR10EZPF3483 additionally features high voltage capability. Selection depends on specific circuit voltage requirements and preferred supplier.

Q: Is the temperature coefficient identical across all parts?

A: Yes. All parts, including the main component and all substitutes, specify ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating temperature range, ensuring thermal performance equivalence.
