Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F84R5CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 84.5 Ohms with ±1% tolerance, power rating of 0.125W (1/8W), temperature coefficient of ±100ppm/°C, and operating temperature range of -55°C ~ 155°C.

Mechanical Compatibility: 0805 (2012 Metric) package format with 2 terminations and compatible physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Compliance Alignment: ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status.

Composition: Thick film construction.

All identified substitutes meet these core parameters and are suitable for direct replacement in applications where the RCS2012F84R5CS is specified.

Parameter Comparison

Engineering Selection Recommendations

All four components listed are active production parts with ROHS3 compliance and identical electrical specifications. Selection among these substitutes is based on application-specific requirements:

CRCW080584R5FKEA (Vishay Dale): Features automotive AEC-Q200 qualification and the lowest seated height (0.020" / 0.50mm), suitable for space-constrained automotive and industrial applications requiring enhanced reliability standards.

ERJ-6ENF84R5V (Panasonic): Provides automotive AEC-Q200 qualification with the highest seated height (0.028" / 0.70mm), appropriate for applications where thermal dissipation or mechanical robustness is prioritized.

RC0805FR-0784R5L (YAGEO): Offers moisture-resistant construction with intermediate seated height (0.024" / 0.60mm), suitable for general industrial and consumer applications without automotive qualification requirements.

RCS2012F84R5CS (Samsung): Original specification with anti-sulfur and moisture-resistant features, appropriate for applications where the original manufacturer specification is mandated or preferred.

Frequently Asked Questions (FAQ)

Q: Can CRCW080584R5FKEA replace RCS2012F84R5CS in non-automotive applications?

A: Yes. Both components share identical electrical parameters (84.5 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), package format (0805), and compliance status (ROHS3, MSL 1). The automotive AEC-Q200 qualification of CRCW080584R5FKEA does not restrict its use in non-automotive circuits.

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

A: Seated height variations (0.020" to 0.028") may affect PCB layout clearance, particularly in high-density designs or applications with height constraints. CRCW080584R5FKEA (0.020") offers the most compact profile, while ERJ-6ENF84R5V (0.028") provides maximum clearance. Verify PCB design requirements before selection.

Q: Are all substitute parts suitable for high-temperature applications?

A: Yes. All components operate across the identical temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient, meeting the thermal requirements of the original RCS2012F84R5CS specification.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction (RCS2012F84R5CS) protects against sulfur-containing atmospheric corrosion, while moisture-resistant construction (RC0805FR-0784R5L) provides protection against humidity ingress. Both features are protective mechanisms; selection depends on environmental exposure conditions.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided PCB layout accommodates the maximum seated height of the selected substitute. All parts conform to 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and use identical 2-termination configuration, enabling direct footprint compatibility.
