Substitute Part Grouping Explanation

Substitute parts for the RC6432F86R6CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 86.6 Ohms, tolerance of ±1%, and power rating of 1W must be identical across all substitute candidates.

Mechanical Compatibility: Package designation 2512 (6432 Metric) ensures physical interchangeability. Dimensional variations within the specified package standard are acceptable.

Environmental Specifications: Operating temperature range of -55°C ~ 155°C and temperature coefficient of ±100ppm/°C must be maintained. Moisture Sensitivity Level 1 (Unlimited) is required.

Compliance Requirements: ROHS3 compliance and REACH Unaffected status are mandatory for substitution eligibility.

Composition: Thick film construction is required for all substitute parts.

The following parts meet these criteria and are classified as direct substitutes:

AC2512FK-0786R6L (YAGEO) — Upgrade substitute with automotive AEC-Q200 qualification
CRCW251286R6FKEG (Vishay Dale) — Similar substitute with automotive AEC-Q200 qualification
RMCF2512FT86R6 (Stackpole Electronics Inc) — Similar substitute with automotive AEC-Q200 qualification

RMCF2512FT86R6 (Stackpole Electronics Inc): This part carries AEC-Q200 automotive qualification and maintains identical dimensional specifications to the original RC6432F86R6CS. Selection is appropriate for direct form-fit-function replacement in automotive and industrial applications.

All substitute parts are Active product status with ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0786R6L be used as a direct replacement for RC6432F86R6CS?

A: Yes. Both parts share identical electrical specifications (86.6 Ohms ±1%, 1W), operate across the same temperature range (-55°C ~ 155°C), and are packaged in the 2512 (6432 Metric) form factor. The AC2512FK-0786R6L includes additional AEC-Q200 automotive qualification.

Q: What is the difference between the three substitute parts?

A: All three substitute parts (AC2512FK-0786R6L, CRCW251286R6FKEG, RMCF2512FT86R6) meet identical electrical and mechanical requirements. Differences exist in packaging format (Tape & Reel versus Cut Tape & Digi-Reel), manufacturer series designation, and minor dimensional variations within the 2512 package specification. All carry AEC-Q200 automotive qualification.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations are within the 2512 (6432 Metric) package standard. Length ranges from 0.248" to 0.250" (6.30mm to 6.35mm), width ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.026" to 0.028" (0.65mm to 0.70mm). These variations are acceptable for standard PCB footprint designs.

Q: Does the RC6432F86R6CS require automotive qualification?

A: The RC6432F86R6CS does not specify automotive qualification. All substitute parts include AEC-Q200 automotive qualification, which represents an enhancement over the original specification and does not restrict substitution.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture control requirements. All parts in this comparison carry MSL 1 designation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The RC6432F86R6CS and all substitute parts are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.
