Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3483CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 348 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

All four substitute parts listed meet these criteria and are therefore direct functional equivalents suitable for circuit board replacement without design modification.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F3483CS and meet identical electrical and mechanical specifications. Selection among these alternatives is based on the following factors:

CRCW0805348KFKEA (Vishay Dale): Automotive AEC-Q200 rated. Lowest seated height at 0.020" (0.50mm). Suitable for applications requiring automotive-grade qualification with space-constrained PCB layouts.

ERJ-6ENF3483V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Highest seated height at 0.028" (0.70mm). Suitable for automotive applications with standard PCB clearance requirements.

KTR10EZPF3483 (Rohm Semiconductor): Automotive AEC-Q200 rated with High Voltage feature designation. Seated height 0.026" (0.65mm). Suitable for automotive and high-voltage circuit applications.

RC0805FR-07348KL (YAGEO): Moisture-resistant construction matching the original part's environmental protection. Seated height 0.024" (0.60mm). Suitable for general industrial and consumer applications with moisture exposure concerns.

All parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 rating, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805348KFKEA replace RCS2012F3483CS in non-automotive applications?

A: Yes. The CRCW0805348KFKEA meets all electrical and mechanical specifications of the RCS2012F3483CS. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. The part is fully compatible.

Q: What is the significance of the height difference between substitute parts?

A: Seated height variations (0.020" to 0.028") are within the 0805 package specification tolerance. These differences are relevant only for PCB designs with vertical space constraints, such as stacked component layouts or enclosure clearance limitations. For standard applications, height variation is not a compatibility factor.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, matching the original RCS2012F3483CS packaging format for automated assembly compatibility.

Q: Does the "High Voltage" feature of KTR10EZPF3483 indicate higher voltage rating than other substitutes?

A: The provided specifications do not include voltage rating data for any part. The "High Voltage" feature designation for KTR10EZPF3483 is noted in the input data but voltage specifications are not provided for comparison. Selection based on voltage requirements requires additional voltage rating documentation.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts are mechanically and electrically equivalent to the RCS2012F3483CS with identical 0805 package footprints, termination count, and electrical parameters. Direct PCB substitution is supported without design modification.

Q: What is the difference between "Anti-Sulfur, Moisture Resistant" and "Automotive AEC-Q200" features?

A: Anti-sulfur and moisture-resistant features address environmental protection against specific contaminants. AEC-Q200 is an automotive industry qualification standard covering reliability and performance requirements. These are different feature categories. The RC0805FR-07348KL emphasizes environmental protection, while CRCW0805348KFKEA, ERJ-6ENF3483V, and KTR10EZPF3483 emphasize automotive qualification.
