• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

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

Compliance Parameters (Required):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Composition remains thick film across all alternatives. Packaging format is Tape & Reel (TR) for all parts listed.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F2433CS, CRCW0805243KFKEA, ERJ-6ENF2433V, and RC0805FR-07243KL—are Active product status components with identical electrical specifications and mechanical compatibility.

Compliance Alignment: All parts are ROHS3 Compliant, REACH Unaffected, and carry MSL Rating 1 (Unlimited), meeting standard industrial and commercial application requirements.

Automotive Qualification: CRCW0805243KFKEA (Vishay Dale) and ERJ-6ENF2433V (Panasonic) carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade applications where enhanced reliability standards are required.

Feature Differentiation: RCS2012F2433CS includes anti-sulfur construction in addition to moisture resistance. RC0805FR-07243KL specifies moisture-resistant construction. CRCW0805243KFKEA and ERJ-6ENF2433V specify automotive AEC-Q200 qualification as their primary feature designation.

Height Variation: Seated height ranges from 0.020" (0.50mm) to 0.028" (0.70mm). All values remain within standard 0805 package specifications and do not restrict PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805243KFKEA replace RCS2012F2433CS in non-automotive applications?

A: Yes. CRCW0805243KFKEA meets all electrical and mechanical specifications required for direct substitution. AEC-Q200 qualification is an additional feature that does not restrict use in standard industrial or commercial circuits.

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

A: Height variation (0.020" to 0.028") reflects manufacturing tolerance ranges within the 0805 package specification. All values are within acceptable limits for standard PCB assembly processes and do not affect electrical performance or mechanical fit.

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

A: Yes. All parts listed—RCS2012F2433CS, CRCW0805243KFKEA, ERJ-6ENF2433V, and RC0805FR-07243KL—are supplied in Tape & Reel (TR) format suitable for automated assembly.

Q: Does anti-sulfur construction in RCS2012F2433CS provide functional advantage over other substitutes?

A: Anti-sulfur construction addresses environmental corrosion in high-sulfur industrial environments. For standard applications, this feature is not functionally required. Substitute parts without explicit anti-sulfur designation remain compliant with ROHS3 and REACH standards.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficient (±100ppm/°C), ensuring equivalent performance in thermal cycling and high-temperature environments.

Q: What is the difference between REACH Unaffected and ROHS3 Compliant status?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive requirements. REACH Unaffected indicates the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. Both certifications are present on all listed parts.
