Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F8662CS is determined by strict equivalence across the following critical parameters: resistance value (86.6 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The substitute parts are categorized as follows:

Direct Equivalents maintain all electrical and mechanical specifications identical to the main part, including power rating (0.063W) and moisture resistant features where applicable.

Upgrade Substitutes provide enhanced specifications (higher power rating or automotive qualification) while maintaining core electrical parameters and package compatibility.

Similar Substitutes match all critical electrical and mechanical parameters but may include additional certifications (automotive AEC-Q200) or feature enhancements that do not compromise compatibility.

All substitute parts listed share the same 0402 package footprint, dimensional specifications (0.039" L x 0.020" W / 1.00mm x 0.50mm), and termination count (2), ensuring direct PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: RC0402FR-0786K6L (YAGEO) and CR0402-FX-8662GLF (Bourns Inc.) provide direct functional equivalence to the RC1005F8662CS with identical electrical specifications and package compatibility. RC0402FR-0786K6L includes moisture resistant features matching the original part and maintains superior inventory availability (151,699 units).

Upgrade Path: ERJ-2RKF8662X (Panasonic Electronic Components) offers enhanced power rating (0.1W vs. 0.063W) with automotive AEC-Q200 qualification. This part is suitable for applications requiring higher thermal margin or automotive-grade reliability while maintaining identical resistance, tolerance, and package specifications.

Automotive-Qualified Alternatives: AC0402FR-0786K6L (YAGEO), CRCW040286K6FKED (Vishay Dale), and RMCF0402FT86K6 (Stackpole Electronics Inc) provide AEC-Q200 automotive qualification with identical electrical parameters. These parts are appropriate for automotive and mission-critical applications requiring documented quality standards.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 classification consistent with the original part. Selection should be based on application requirements, supply chain availability, and any automotive or reliability certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0786K6L directly replace RC1005F8662CS without PCB layout modifications?

A: Yes. Both parts share identical 0402 (1005 Metric) package dimensions (0.039" L x 0.020" W), footprint, and two-terminal configuration. No PCB layout changes are required.

Q: What is the difference between the main part and ERJ-2RKF8662X?

A: ERJ-2RKF8662X provides higher power rating (0.1W vs. 0.063W) and includes automotive AEC-Q200 qualification. All electrical parameters (resistance, tolerance, temperature coefficient, operating range) remain identical. The higher power rating provides additional thermal margin in the same package.

Q: Are the automotive AEC-Q200 qualified parts (AC0402FR-0786K6L, CRCW040286K6FKED, RMCF0402FT86K6) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed commercial-grade specifications and are fully compatible with non-automotive applications. AEC-Q200 certification indicates enhanced reliability and quality documentation but does not restrict use to automotive circuits.

Q: Does CR0402-FX-8662GLF lack moisture resistant features compared to RC1005F8662CS?

A: CR0402-FX-8662GLF specifications do not explicitly list moisture resistant features in the provided data. For applications requiring documented moisture resistance, RC0402FR-0786K6L or AC0402FR-0786K6L are recommended alternatives.

Q: What inventory considerations apply when selecting a substitute?

A: RC0402FR-0786K6L (YAGEO) offers the highest inventory availability (151,699 units) among direct equivalents. ERJ-2RKF8662X (Panasonic) provides the largest total stock (397,181 units) if upgrade specifications are acceptable. Inventory levels should be verified with suppliers for current availability.

Q: Are all substitute parts compliant with ROHS3 and REACH regulations?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status identical to the RC1005F8662CS, ensuring regulatory compatibility across all applications.
