AF1210FR-07976RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07976RL is a 976 Ohms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 and features anti-sulfur construction. The part is currently in active production status with 624 units available in stock.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, lead time extensions, or when design requirements permit equivalent alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07976RL is determined by strict equivalence across the following parameters:

• Resistance value: 976 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF9760U manufactured by Panasonic Electronic Components meets all these criteria and qualifies as a direct substitute. Physical dimensions show minor variations within acceptable tolerances for 1210 package specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-14NF9760U is electrically and mechanically equivalent to the AF1210FR-07976RL. Both components satisfy identical electrical specifications, automotive qualification requirements, and regulatory compliance standards.

The primary distinction is product status: AF1210FR-07976RL maintains active production status, while ERJ-14NF9760U is designated as "Not For New Designs." This designation indicates that Panasonic has discontinued this part for new applications, though existing inventory remains available.

For new designs, the AF1210FR-07976RL is the preferred selection due to active production support. The ERJ-14NF9760U is suitable only for legacy system maintenance, repair, or applications where existing design validation has already been completed with this component.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9760U be used as a direct replacement for AF1210FR-07976RL in automotive applications?

A: Yes. Both components meet AEC-Q200 automotive qualification, operate across identical temperature ranges, and maintain equivalent electrical performance. Physical dimensions fall within acceptable tolerances for 1210 package specifications.

Q: What is the significance of the "Not For New Designs" status on the Panasonic part?

A: This designation indicates that Panasonic has discontinued accepting new design registrations for this part number. Existing inventory may be available for purchase, but the manufacturer provides no guarantee of long-term availability or future production. New designs should specify the AF1210FR-07976RL.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist within the 1210 package specification. The Panasonic part is 0.004" longer and 0.004" wider, with 0.004" greater height. These differences are within standard 1210 package tolerances and do not require PCB layout modifications.

Q: Do both parts require identical moisture handling procedures?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply to both parts.

Q: What compliance certifications apply to both parts?

A: Both AF1210FR-07976RL and ERJ-14NF9760U are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 for export purposes.
