AF1210FR-0723K7L Equivalent & Substitute Parts

Part Overview

The AF1210FR-0723K7L is a 23.7 kOhms ±1% thick film chip resistor manufactured by YAGEO in the 1210 (3225 Metric) package. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility across qualified suppliers is required while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-0723K7L is determined by strict equivalence across the following parameters: resistance value (23.7 kOhms), tolerance (±1%), power rating (0.5W), package type (1210/3225 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The ERJ-14NF2372U from Panasonic Electronic Components meets all these criteria and qualifies as a direct electrical and mechanical substitute. Physical dimensions may vary within acceptable tolerances for the 1210 package footprint, and both parts maintain identical electrical performance characteristics and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The AF1210FR-0723K7L maintains active product status with current manufacturing availability. The ERJ-14NF2372U is designated as "Not For New Designs" by Panasonic, indicating it remains available for existing applications but is not recommended for new circuit development. Both parts satisfy identical electrical specifications and automotive compliance requirements. Selection between these parts should prioritize the AF1210FR-0723K7L for new designs due to its active status. The ERJ-14NF2372U serves as a valid substitute for legacy system support, field replacements, or applications where supply of the primary part is constrained. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2372U be used as a direct replacement for AF1210FR-0723K7L in new designs?

A: While ERJ-14NF2372U meets all electrical and mechanical specifications, it carries a "Not For New Designs" status. For new circuit development, AF1210FR-0723K7L is the recommended choice. ERJ-14NF2372U is suitable for field replacements or legacy system maintenance.

Q: Are there physical dimension differences between these parts?

A: Both parts use the 1210 (3225 Metric) package. AF1210FR-0723K7L measures 0.122" L × 0.102" W with 0.024" maximum seated height. ERJ-14NF2372U measures 0.126" L × 0.098" W with 0.028" maximum seated height. These variations remain within standard 1210 package tolerances and do not affect PCB footprint compatibility.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both AF1210FR-0723K7L and ERJ-14NF2372U carry AEC-Q200 automotive qualification ratings and operate across the identical temperature range of -55°C to 155°C.

Q: What is the significance of the anti-sulfur feature on AF1210FR-0723K7L?

A: The anti-sulfur protection on AF1210FR-0723K7L provides enhanced reliability in environments with sulfur-containing contaminants. ERJ-14NF2372U does not specify this feature. For applications in high-sulfur environments, AF1210FR-0723K7L is the preferred selection.

Q: Are both parts RoHS compliant?

A: Yes. Both AF1210FR-0723K7L and ERJ-14NF2372U are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), suitable for standard manufacturing and storage conditions.
