AF1210FR-07105RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07105RL is a 105 Ohm ±1% thick film chip resistor in 1210 (3225 Metric) package rated for 0.5W power dissipation. Manufactured by YAGEO under the AF series, this component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for harsh automotive environments operating across -55°C to 155°C. The part is currently in active production status with 899 units in stock.

Substitute parts become necessary when the primary manufacturer's inventory is depleted, lead times extend beyond project requirements, or design flexibility across qualified suppliers is required while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07105RL is determined by strict equivalence across the following parameters:

• Resistance value: 105 Ohms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package designation: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed maintain these electrical and mechanical specifications, ensuring direct interchangeability in PCB assembly and circuit operation without design modification.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210105RFKEA (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains active product status, ensuring long-term availability and supply chain stability. Physical dimensions align closely with the original specification, with maximum seated height identical at 0.60mm, supporting direct PCB layout compatibility.

ERJ-14NF1050U (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This designation indicates the manufacturer is transitioning the product line and does not recommend its use in new circuit designs. Existing inventory of 69,224 units remains available for legacy system support or repair applications where the original AF1210FR-07105RL is unavailable. The maximum seated height of 0.70mm introduces a 0.10mm variance that may require PCB clearance verification in space-constrained assemblies.

Both substitute parts satisfy automotive AEC-Q200 qualification, ROHS3 compliance, and MSL 1 moisture sensitivity requirements, confirming suitability for the same operating environments as the primary part.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210105RFKEA be used as a direct replacement for AF1210FR-07105RL without PCB modification?

A: Yes. Both parts share identical electrical specifications (105 Ohms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C) and package designation (1210/3225 Metric). Physical dimensions differ slightly (3.20mm x 2.50mm vs. 3.10mm x 2.60mm), but these variations remain within standard PCB pad tolerances. Maximum seated height is identical at 0.60mm, confirming clearance compatibility.

Q: Why is ERJ-14NF1050U marked "Not For New Designs"?

A: This status indicates Panasonic is discontinuing or transitioning this product line. While the part remains electrically and mechanically equivalent, the manufacturer does not recommend its use in new circuit designs due to uncertain long-term availability. It is suitable for legacy system maintenance or repair where supply of the primary part is exhausted.

Q: Are there dimensional differences that affect PCB assembly?

A: The AF1210FR-07105RL measures 3.10mm x 2.60mm with 0.60mm maximum seated height. CRCW1210105RFKEA measures 3.20mm x 2.50mm with 0.60mm maximum seated height. ERJ-14NF1050U measures 3.20mm x 2.50mm with 0.70mm maximum seated height. These variations are within standard 1210 package tolerances and do not require PCB redesign. Verify clearance for ERJ-14NF1050U in applications with height-critical constraints.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. AF1210FR-07105RL, CRCW1210105RFKEA, and ERJ-14NF1050U all carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, confirming equivalence for automotive and harsh environment applications.

Q: What is the inventory status of each part?

A: AF1210FR-07105RL has 899 units in stock. CRCW1210105RFKEA has 13,677 units in stock. ERJ-14NF1050U has 69,224 units in stock. Inventory levels reflect current availability and may change based on supply chain conditions.
