RC2012F84R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F84R5CS is a 0805 (2012 Metric) thick film chip resistor manufactured by Samsung Electro-Mechanics. This component provides 84.5 Ohms resistance with ±1% tolerance and 0.125W (1/8W) power rating. The part is classified as Active and carries ROHS3 compliance with Moisture Sensitivity Level 1 (Unlimited). Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when design specifications permit equivalent components from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F84R5CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 84.5 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitute parts are grouped into two categories based on additional certifications:

Direct Substitutes (Functionally Equivalent): Parts meeting all mandatory parameters without additional automotive qualification.

Direct Substitutes with Automotive Certification (AEC-Q200): Parts meeting all mandatory parameters and carrying AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade components.

Similar Parts (Functionally Equivalent with Discontinued Status): Parts meeting all mandatory parameters but with discontinued product status at the distributor level.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC0805FR-0784R5L (YAGEO) is suitable as a direct substitute. This part maintains moisture resistance equivalent to the primary part and carries Active product status with full ROHS3 compliance.

For Automotive Applications: ERJ-6ENF84R5V (Panasonic Electronic Components), RMCF0805FT84R5 (Stackpole Electronics Inc), or CRCW080584R5FKEA (Vishay Dale) are appropriate selections. All three parts carry AEC-Q200 automotive qualification and Active product status. CRCW080584R5FKEA offers the lowest seated height (0.50mm) among automotive-qualified options.

For Supply Chain Continuity: CRCW080584R5FKEA (Vishay Dale) demonstrates the highest inventory availability (37,293 pieces) and maintains Active product status, supporting long-term supply chain stability.

Parts to Avoid for New Designs: MCR10ERTF84R5 (Rohm Semiconductor) carries Discontinued status at the distributor level and should not be selected for new designs despite meeting all electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F84R5CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the mandatory electrical parameters (84.5 Ohms, ±1% tolerance, 0.125W power rating) and mechanical specifications (0805 package, 2 terminations). Physical height variations (0.50mm to 0.70mm) are within standard PCB assembly tolerances and do not require redesign.

Q: What is the difference between parts with "Moisture Resistant" and "Automotive AEC-Q200" features?

A: Moisture Resistant designation indicates the part meets moisture resistance requirements for general industrial use. Automotive AEC-Q200 designation indicates the part meets automotive industry qualification standards including additional reliability and environmental testing. AEC-Q200 parts are suitable for both automotive and industrial applications.

Q: Is the height difference between substitute parts significant?

A: Height variations range from 0.50mm (CRCW080584R5FKEA) to 0.70mm (ERJ-6ENF84R5V). These differences fall within standard PCB assembly clearance specifications and do not affect electrical performance or mechanical fit in standard 0805 footprints.

Q: Why is MCR10ERTF84R5 listed if it is discontinued?

A: MCR10ERTF84R5 is included for reference purposes only, documenting historical equivalence. This part meets all electrical and mechanical parameters but carries Discontinued status at the distributor level. New designs should select from Active status parts.

Q: Can I use automotive-qualified parts (AEC-Q200) in non-automotive applications?

A: Yes. Automotive-qualified parts exceed industrial application requirements and are fully compatible with standard industrial circuits. AEC-Q200 parts provide additional reliability margin without performance trade-offs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the primary part specification.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part does not require special moisture-controlled storage or handling procedures and can be stored under standard industrial conditions indefinitely.
