AF1210FR-07665RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07665RL is a 665 Ohm ±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 standard with anti-sulfur coating and operates across -55°C to 155°C. The part is currently in active production status with 1041 units in stock.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements mandate alternative qualified suppliers, or when inventory availability necessitates cross-compatible alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07665RL is determined by strict equivalence across the following parameters:

• Resistance value: 665 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package: 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
• Moisture sensitivity: MSL 1

All substitute parts listed maintain these core electrical and mechanical parameters, ensuring direct functional equivalence in automotive and industrial applications. Dimensional variations within supplier tolerances do not affect circuit performance or PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210665RFKEA (Vishay Dale) is the primary substitute for AF1210FR-07665RL. Both components maintain active production status, full AEC-Q200 automotive qualification, and ROHS3 compliance. Inventory availability for CRCW1210665RFKEA is 5979 units, providing supply security. Dimensional tolerances between the two parts fall within standard PCB assembly specifications.

ERJ-14NF6650U (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" product status. This part is suitable only for legacy system maintenance, field repairs, or applications where existing inventory must be maintained. The maximum height specification of 0.028" (0.70mm) versus 0.024" (0.60mm) for the primary part may require clearance verification in space-constrained applications. Panasonic inventory of 15960 units provides availability for replacement applications.

For new automotive designs, CRCW1210665RFKEA is the preferred substitute. For legacy or maintenance applications, ERJ-14NF6650U remains functionally qualified.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210665RFKEA be used as a direct replacement for AF1210FR-07665RL in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, maintain identical electrical specifications (665 Ohms ±1%, 0.5W, ±100ppm/°C), and are ROHS3 compliant. Dimensional variations (length 3.20mm vs 3.10mm, width 2.50mm vs 2.60mm) are within standard 1210 package tolerances and do not affect PCB assembly or circuit performance.

Q: Why is ERJ-14NF6650U marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. The part remains available for existing applications and field service. The maximum height of 0.028" (0.70mm) versus 0.024" (0.60mm) for active alternatives should be verified for space-constrained designs.

Q: Are all three parts interchangeable in the same PCB footprint?

A: Yes. All three parts use the 1210 (3225 Metric) package with identical termination configuration. Minor dimensional variations fall within standard PCB design tolerances and do not require footprint modification.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, AEC-Q200 automotive qualified, and carry MSL 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for all three parts.

Q: Which substitute should be selected for new automotive designs?

A: CRCW1210665RFKEA (Vishay Dale) is the recommended substitute for new designs. It maintains active production status and equivalent automotive qualification to the primary part.
