Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F7680CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (768 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must match exactly. Power rating equivalence is established at 0.063W (1/16W) for direct substitutes and at 0.1W (1/10W) for upgrade substitutes with higher power dissipation capability.

Mechanical Parameters: Package designation (0402 / 1005 Metric), physical dimensions (0.039" L x 0.020" W), maximum seated height (0.016" or 0.40mm), and termination count (2) must be identical to ensure PCB footprint compatibility and assembly process compatibility.

Compliance Parameters: RoHS3 compliance, REACH unaffected status, MSL 1 rating, and EAR99 ECCN classification are maintained across all substitute parts. Automotive AEC-Q200 certification is present in certain substitute options and represents an enhanced qualification level.

Composition: All substitute parts utilize thick film construction, consistent with the main part specification.

Substitute parts are categorized as Direct Substitutes (identical specifications), Upgrade Substitutes (enhanced power rating), or Similar Substitutes (automotive-qualified variants with equivalent base specifications).

Engineering Selection Recommendations

Direct Substitutes (CR0402-FX-7680GLF, RC0402FR-07768RL): These parts provide complete electrical and mechanical equivalence to the RC1005F7680CS. Both maintain identical power ratings (0.063W), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). CR0402-FX-7680GLF from Bourns Inc. and RC0402FR-07768RL from YAGEO are suitable for direct replacement in applications where the original specification is required. RC0402FR-07768RL includes moisture-resistant features matching the main part.

Upgrade Substitute (ERJ-2RKF7680X): The Panasonic ERJ-2RKF7680X offers enhanced power dissipation capability at 0.1W (1/10W) compared to the 0.063W (1/16W) rating of the main part. This upgrade maintains all other electrical parameters and includes Automotive AEC-Q200 qualification.

These parts meet automotive qualification standards while maintaining electrical and mechanical equivalence.

Q: What is the moisture sensitivity level (MSL) for all substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake requirements. This matches the RC1005F7680CS specification and ensures consistent handling and storage requirements across all equivalent parts.

Q: Can substitute parts be mixed in the same production batch?

A: Yes. All substitute parts share identical electrical specifications (768 Ohms ±1%, 0.063W or 0.1W, ±100ppm/°C), mechanical compatibility (0402 package, 1.00mm x 0.50mm), and compliance ratings (RoHS3, MSL 1). Parts may be used interchangeably within the same design provided power rating requirements are met. Automotive-qualified parts (AEC-Q200) may be substituted for non-automotive parts without functional impact.
