Substitute Part Grouping Explanation

Substitution eligibility for the AC0402FR-07976RL is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (976 Ohms), tolerance (±1%), and power rating (0.063W / 1/16W) must be identical
Package Compatibility: 0402 (1005 Metric) form factor with matching physical dimensions (0.039" L x 0.020" W)
Material & Composition: Thick film construction with ±100ppm/°C temperature coefficient
Environmental Rating: Operating temperature range -55°C ~ 155°C and MSL 1 classification
Compliance: ROHS3 compliance and REACH unaffected status required for regulatory alignment

All three substitute parts meet these criteria and are qualified for direct replacement in automotive and industrial applications requiring AEC-Q200 or equivalent moisture-resistant thick film resistors.

Engineering Selection Recommendations

AC0402FR-07976RL (Original): Recommended for automotive applications requiring explicit AEC-Q200 qualification with moisture-resistant construction. Lowest seated height (0.37mm) suitable for space-constrained PCB layouts.

RC0402FR-07976RL: YAGEO alternative with identical electrical performance and moisture resistance. Lacks AEC-Q200 automotive rating; suitable for industrial and consumer applications where automotive qualification is not mandated. Higher inventory availability (40401 units).

CRCW0402976RFKED: Vishay Dale equivalent with AEC-Q200 automotive qualification. Functionally interchangeable with the original part for automotive designs. Highest inventory availability (63916 units) among substitute options.

RMCF0402FT976R: Stackpole Electronics alternative with AEC-Q200 automotive qualification. Functionally interchangeable with the original part for automotive designs. Comparable inventory availability (64293 units).

Selection between substitute parts should prioritize AEC-Q200 qualification for automotive applications (CRCW0402976RFKED or RMCF0402FT976R) or consider RC0402FR-07976RL for non-automotive industrial use cases where automotive certification is not required.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07976RL replace AC0402FR-07976RL in automotive applications?

A: RC0402FR-07976RL lacks AEC-Q200 automotive qualification present in the original AC0402FR-07976RL. For automotive designs requiring AEC-Q200 compliance, use CRCW0402976RFKED or RMCF0402FT976R instead. RC0402FR-07976RL is suitable for industrial and consumer applications.

Q: Are all substitute parts mechanically compatible with the original AC0402FR-07976RL?

A: All substitute parts use the 0402 (1005 Metric) package with identical length (0.039") and width (0.020"). The original part has a maximum seated height of 0.015" (0.37mm), while substitutes measure 0.016" (0.40mm). This 0.01mm difference is within standard PCB assembly tolerances and does not affect mechanical compatibility.

Q: What is the difference between AC and RC series resistors from YAGEO?

A: The AC series includes AEC-Q200 automotive qualification, while the RC_L series provides moisture-resistant thick film construction without automotive certification. Both share identical electrical specifications (976 Ohms ±1%, 0.063W, ±100ppm/°C).

Q: Can these 0402 resistors be used interchangeably in high-temperature applications?

A: All parts operate across -55°C ~ 155°C with ±100ppm/°C temperature coefficient. They are functionally equivalent for temperature performance within this range.

Q: Which substitute offers the best inventory availability?

A: CRCW0402976RFKED (Vishay Dale) provides the highest inventory at 63916 units, followed by RMCF0402FT976R (Stackpole) at 64293 units. RC0402FR-07976RL (YAGEO) offers 40401 units.

Q: Are all parts ROHS3 compliant?

A: Yes. AC0402FR-07976RL, RC0402FR-07976RL, CRCW0402976RFKED, and RMCF0402FT976R are all ROHS3 compliant with REACH unaffected status.
