AC1210FR-0723K7L Equivalent & Substitute Parts

Part Overview

The AC1210FR-0723K7L is a 23.7 kOhms ±1% thick film chip resistor manufactured by YAGEO in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with moisture-resistant construction. The part is currently in active production status. Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements mandate alternative qualified sources, or when inventory availability necessitates cross-compatible alternatives from other manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the AC1210FR-0723K7L is determined by strict equivalence across the following critical parameters:

• Resistance value: 23.7 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Automotive qualification: AEC-Q200
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF2372U from Panasonic Electronic Components meets all electrical and mechanical parameters required for direct substitution. Physical dimensions show minor variations within acceptable tolerances for PCB assembly compatibility.

Engineering Selection Recommendations

The AC1210FR-0723K7L maintains active production status and is the primary selection for new designs. The ERJ-14NF2372U from Panasonic is classified as "Not For New Designs" and should be reserved for legacy system support, field replacements, or situations where supply of the primary part is unavailable.

Both parts satisfy identical electrical specifications and AEC-Q200 automotive qualification requirements. Physical dimension variations between the two parts are within standard PCB assembly tolerances and do not affect functional performance or thermal characteristics in typical circuit applications.

Selection between these parts should be based on availability, supply chain requirements, and design phase status rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2372U be used as a direct replacement for AC1210FR-0723K7L in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (23.7 kOhms ±1%, 0.5W, ±100ppm/°C), and are packaged in the 1210 (3225 Metric) format. Physical dimensions vary slightly but remain within PCB assembly compatibility tolerances.

Q: What is the significance of the "Not For New Designs" status on the Panasonic part?

A: This designation indicates that Panasonic has discontinued active development of the ERJ-14NF2372U series. The part remains available for existing applications and field replacements but should not be selected for new product designs. The YAGEO AC1210FR-0723K7L is the recommended choice for new designs.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist. The Panasonic part is 0.004" longer (3.20mm vs 3.10mm) and 0.004" narrower (2.50mm vs 2.60mm) in length and width, with 0.004" greater seated height (0.70mm vs 0.60mm). These differences fall within standard PCB assembly tolerances and do not require layout modifications.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both the AC1210FR-0723K7L and ERJ-14NF2372U carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture precautions are required during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and meet current environmental and regulatory requirements for electronic component manufacturing and use.
