AF1210FR-07374RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07374RL is a 374 Ohms ±1% 0.5W chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 845 units in stock.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, lead time extensions, or when design flexibility permits selection from qualified alternative sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07374RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 374 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

The ERJ-14NF3740U from Panasonic Electronic Components meets all these electrical and mechanical requirements. Minor dimensional variations in length, width, and height are within acceptable tolerances for 1210 package specifications and do not affect circuit performance or PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-14NF3740U qualifies as a direct electrical and mechanical substitute for the AF1210FR-07374RL. Both parts satisfy identical electrical specifications, package requirements, and automotive compliance standards. The ERJ-14NF3740U carries a "Not For New Designs" product status, indicating it remains available for replacement and legacy applications but is not recommended for new product development initiatives.

For active production designs, the AF1210FR-07374RL maintains active product status and should be the primary selection. The ERJ-14NF3740U is appropriate for field replacements, repair operations, and applications where supply continuity from the primary source is interrupted.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3740U be used as a direct replacement for AF1210FR-07374RL in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across the identical temperature range (-55°C to 155°C), and carry equivalent electrical specifications (374 Ohms ±1%, 0.5W). The 1210 package footprint is identical, and dimensional variations are within standard package tolerances.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF3740U?

A: This designation indicates the part is in mature production but not recommended for incorporation into new product designs. It remains available for replacement stock and legacy system support. New designs should prioritize the AF1210FR-07374RL, which carries active product status.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1210 package specification. The ERJ-14NF3740U is 0.004" longer and 0.004" wider, with 0.004" greater maximum height. These differences fall within standard 1210 package tolerances and do not affect PCB assembly or circuit performance.

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

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

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical EAR99 and HTSUS classifications. Automotive AEC-Q200 qualification is equivalent on both parts.
