Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F4870CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (487 Ohms), 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 number of terminations (2) are mandatory for PCB footprint compatibility. Physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) ensure mechanical fit.

Material & Composition: Thick film construction is the specified composition type.

Regulatory Compliance: RoHS3 compliance and MSL 1 rating are required for environmental and moisture handling standards.

Substitute parts are classified as Direct or Similar based on feature alignment. Direct substitutes match all parameters including moisture resistance features. Similar substitutes introduce additional certifications (AEC-Q200 automotive qualification) while maintaining core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (RC0805FR-07487RL - YAGEO): This part provides direct functional equivalence to the RC2012F4870CS with identical electrical specifications, thermal characteristics, and moisture resistance features. Both components are classified as Active products with RoHS3 compliance. The RC0805FR-07487RL exhibits a slightly lower seated height (0.024" vs 0.026"), which presents no compatibility issues for standard PCB assembly processes. This substitute is suitable for applications where moisture-resistant thick film construction is the primary requirement.

Similar Substitution with Automotive Qualification (CRCW0805487RFKEA - Vishay Dale, ERJ-6ENF4870V - Panasonic, RMCF0805FT487R - Stackpole): These three parts maintain all core electrical and mechanical specifications while adding AEC-Q200 automotive qualification. All three are Active products with RoHS3 compliance and MSL 1 rating. The CRCW0805487RFKEA offers the lowest seated height (0.020"), while ERJ-6ENF4870V provides the highest inventory availability (165,299 pcs). These substitutes are applicable in applications requiring automotive-grade reliability or where AEC-Q200 certification is specified. Seated height variations (0.020" to 0.028") remain within acceptable tolerances for standard surface-mount assembly.

Selection between substitute parts should be based on procurement availability, lead time requirements, and specific application certifications. All identified substitutes maintain electrical performance equivalence and mechanical compatibility with the original RC2012F4870CS specification.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07487RL (YAGEO) be used as a direct replacement for RC2012F4870CS (Samsung)?

A: Yes. Both parts share identical resistance (487 Ohms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and RoHS3 compliance. The seated height difference (0.024" vs 0.026") does not affect PCB footprint compatibility.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes (RC0805FR-07487RL) match all electrical, mechanical, and feature specifications of the original part. Similar substitutes (CRCW0805487RFKEA, ERJ-6ENF4870V, RMCF0805FT487R) maintain identical core specifications but include additional AEC-Q200 automotive qualification. All maintain functional equivalence.

Q: Are the automotive-qualified parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents an additional quality and reliability standard. Parts meeting AEC-Q200 criteria are fully compatible with non-automotive applications and provide equivalent or superior performance to non-qualified alternatives.

Q: Does the seated height variation affect PCB assembly?

A: No. All substitute parts have seated heights ranging from 0.020" to 0.028" (0.50mm to 0.70mm), which fall within standard PCB assembly tolerances for 0805 package components. Height variations do not impact reflow soldering, component placement, or electrical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitutes (RC0805FR-07487RL, CRCW0805487RFKEA, ERJ-6ENF4870V, RMCF0805FT487R) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RC2012F4870CS specification.

Q: Which substitute offers the best inventory availability?

A: ERJ-6ENF4870V (Panasonic) provides the highest inventory level at 165,299 pcs. RC0805FR-07487RL (YAGEO) offers 34,905 pcs. Both represent substantial stock positions for supply chain continuity.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All substitute parts are mechanically and electrically interchangeable within the same PCB footprint (0805 / 2012 Metric). No design modifications are required for substitution.
