AF1210FR-07931RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07931RL is a 931 Ohms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component is designed for automotive applications and meets AEC-Q200 qualification standards with anti-sulfur coating. The part is currently in active production status. Substitute parts are necessary when primary inventory is unavailable, when design requirements mandate alternative manufacturers, or when supply chain optimization requires qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07931RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 931 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W (exact match required)
• Package designation: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The ERJ-14NF9310U from Panasonic Electronic Components meets all electrical and mechanical requirements for direct substitution. Physical dimensions may vary within acceptable tolerances for the 1210 package footprint.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-14NF9310U qualifies as a direct electrical and mechanical equivalent to the AF1210FR-07931RL. Both components satisfy AEC-Q200 automotive qualification requirements and maintain identical electrical performance across the specified operating temperature range.

The primary distinction between these parts is product lifecycle status. The AF1210FR-07931RL maintains active production status, while the ERJ-14NF9310U is designated as "Not For New Designs." For new product development, the AF1210FR-07931RL is the preferred selection. For existing designs or applications where the ERJ-14NF9310U is already qualified, continued use is supported by equivalent electrical and mechanical specifications.

Both components are ROHS3 compliant and carry unlimited moisture sensitivity classification, suitable for standard surface mount assembly processes without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9310U be used as a direct replacement for AF1210FR-07931RL in existing designs?

A: Yes. Both components share identical electrical specifications (931 Ohms ±1%, 0.5W), operate across the same temperature range (-55°C to 155°C), and carry AEC-Q200 automotive qualification. Physical dimensions are within acceptable tolerances for the 1210 package footprint.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF9310U?

A: This designation indicates that Panasonic has discontinued active development and new production of this part number. Existing inventory may be available, but the manufacturer does not recommend this part for new product designs. The AF1210FR-07931RL, with active status, is the recommended choice for new applications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1210 package specification. AF1210FR-07931RL measures 0.122" L x 0.102" W (3.10mm x 2.60mm) with 0.024" maximum seated height. ERJ-14NF9310U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" maximum seated height. Both fall within acceptable 1210 package tolerances and are compatible with standard PCB footprints designed for this package.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard surface mount assembly processes apply to both parts.

Q: What compliance certifications apply to both parts?

A: Both the AF1210FR-07931RL and ERJ-14NF9310U are ROHS3 compliant and REACH unaffected. Both carry AEC-Q200 automotive qualification for use in automotive applications.
