AF1210FR-07237RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07237RL is a 237 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 922 units in stock.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and automotive compliance ratings are maintained across different manufacturers. This ensures design flexibility and supply chain continuity without compromising circuit performance or reliability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07237RL is determined by strict equivalence across the following parameters:

• Resistance value: 237 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

All identified substitute parts meet these electrical and mechanical criteria. Variations in physical dimensions (length, width, height) within standard tolerances do not affect substitutability provided the package code remains 1210 and all electrical parameters are maintained.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210237RFKEA (Vishay Dale) is the primary substitute for AF1210FR-07237RL. Both components are in active production status with full automotive AEC-Q200 compliance and ROHS3 certification. Electrical and thermal characteristics are identical. This part is suitable for new designs and ongoing production.

ERJ-14NF2370U (Panasonic) meets all electrical and mechanical equivalence criteria with identical AEC-Q200 and ROHS3 compliance. However, this part carries a "Not For New Designs" status, indicating the manufacturer has discontinued active development. This part remains suitable for replacement applications and legacy design support where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210237RFKEA directly replace AF1210FR-07237RL in automotive applications?

A: Yes. Both parts are AEC-Q200 rated with identical resistance (237 Ohms ±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The 1210 package designation ensures mechanical compatibility on standard PCB layouts.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF2370U?

A: This designation indicates Panasonic has transitioned this product line away from active development. The part remains electrically and mechanically equivalent and is available in inventory. It is suitable for replacement and repair applications but should not be selected for new product designs where long-term supply continuity is required.

Q: Are there dimensional differences between these three parts?

A: Minor variations exist within standard tolerances. AF1210FR-07237RL measures 0.122" L × 0.102" W with 0.024" max height. CRCW1210237RFKEA measures 0.126" L × 0.098" W with 0.024" max height. ERJ-14NF2370U measures 0.126" L × 0.098" W with 0.028" max height. All remain within 1210 package specifications and are compatible with standard PCB footprints.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, MSL 1 rated, and carry AEC-Q200 automotive certification. REACH status is unaffected for all parts.

Q: Which part should be selected for a new automotive design?

A: CRCW1210237RFKEA is the recommended choice for new designs due to its active production status and full manufacturer support. AF1210FR-07237RL remains an acceptable alternative if YAGEO supply is preferred.
