Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F86R6CS is determined by strict equivalence across the following critical parameters: resistance value (86.6 Ohms), tolerance (±1%), package format (0402/1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (RoHS3, REACH Unaffected, EAR99).

Substitute parts are classified into two categories:

Direct Equivalents: Parts matching all electrical and mechanical specifications of the main part, including identical power rating (0.063W/1/16W) and moisture resistant features without automotive qualification.

Upgrade Equivalents: Parts matching all core specifications but with enhanced power rating (0.1W/1/10W) or additional automotive AEC-Q200 qualification. These parts provide superior performance margins and are suitable for applications requiring higher reliability standards.

All substitute parts maintain identical package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), height (0.016" / 0.40mm maximum), and two-termination configuration.

Engineering Selection Recommendations

RC0402FR-0786R6L (YAGEO): Direct functional equivalent with identical electrical and mechanical specifications. Suitable for applications where the primary Samsung part is unavailable. Maintains equivalent moisture resistance and RoHS3 compliance. Recommended for non-automotive applications with standard reliability requirements.

ERJ-2RKF86R6X (Panasonic Electronic Components): Upgrade substitute with enhanced 0.1W power rating providing 58% higher power dissipation margin compared to the 0.063W main part. Includes automotive AEC-Q200 qualification. Recommended for applications requiring automotive-grade reliability or where thermal margin enhancement is beneficial. Physically and electrically compatible with identical package and operating temperature range.

CRCW040286R6FKED (Vishay Dale): Direct equivalent with automotive AEC-Q200 qualification and identical 0.063W power rating. Maintains all electrical specifications of the main part while providing automotive-grade reliability certification. Recommended for automotive applications or designs requiring AEC-Q200 compliance.

RMCF0402FT86R6 (Stackpole Electronics Inc): Direct equivalent with automotive AEC-Q200 qualification and identical 0.063W power rating. Maintains all electrical specifications of the main part while providing automotive-grade reliability certification. Recommended for automotive applications or designs requiring AEC-Q200 compliance.

All substitute parts are Active status products with full RoHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0786R6L be used as a direct replacement for RC1005F86R6CS?

A: Yes. RC0402FR-0786R6L is a direct equivalent with identical resistance (86.6 Ohms), tolerance (±1%), power rating (0.063W), package (0402), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Both parts are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and ERJ-2RKF86R6X?

A: ERJ-2RKF86R6X differs in two aspects: power rating is increased to 0.1W (versus 0.063W in the main part), and it includes automotive AEC-Q200 qualification. All other electrical parameters, package format, and operating temperature range remain identical. The higher power rating provides additional thermal margin.

Q: Are CRCW040286R6FKED and RMCF0402FT86R6 suitable for non-automotive applications?

A: Yes. Both parts are electrically and mechanically equivalent to the main part with identical 86.6 Ohms resistance, ±1% tolerance, 0.063W power rating, and 0402 package. The automotive AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive applications. These parts are suitable for any application compatible with the main part.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts maintain identical package dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). All parts have two terminations and are compatible with identical PCB footprints.

Q: What is the moisture sensitivity level for all these parts?

A: All parts, including the main part and all substitutes, have MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements.

Q: Are there any compliance differences between the main part and substitutes?

A: All parts are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. The automotive-qualified substitutes (ERJ-2RKF86R6X, CRCW040286R6FKED, RMCF0402FT86R6) carry additional AEC-Q200 certification, which is a superset of standard compliance and does not create incompatibility.
