AC1206FR-0723K2L Equivalent & Substitute Parts

Part Overview

The AC1206FR-0723K2L is a 23.2 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This automotive-grade component meets AEC-Q200 qualification and includes moisture-resistant construction. The part is currently active in production with 781 pieces in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward alternative manufacturers, or when specific feature enhancements (such as increased power rating or pulse withstanding capability) are required while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Resistance value: 23.2 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature Coefficient: ±100ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Substitution Criteria (Allowable Variations):

Power Rating: 0.25W minimum (higher ratings acceptable for enhanced capability)
Automotive Rating: AEC-Q200 certification (optional; non-automotive variants acceptable if electrical parameters match)
Moisture Resistance: Feature enhancement (optional; presence does not disqualify non-moisture-resistant variants)
Pulse Withstanding: Feature enhancement (optional; presence does not disqualify standard variants)

All substitute parts listed below meet the primary criteria. Variations in secondary criteria are noted in the parameter comparison table.

Engineering Selection Recommendations

For Active Production Designs: RC1206FR-0723K2L (YAGEO), RK73H2BTTD2322F (KOA Speer Electronics), CR1206-FX-2322ELF (Bourns), CRCW120623K2FKEA (Vishay Dale), and CRCW120623K2FKEAHP (Vishay Dale) are all suitable direct substitutes with active product status. All meet ROHS3 compliance and MSL 1 requirements.

For Automotive Applications: If AEC-Q200 certification is a design requirement, select from: AC1206FR-0723K2L, RK73H2BTTD2322F, CRCW120623K2FKEA, CRCW120623K2FKEAHP, or ERJ-8ENF2322V.

For Enhanced Power Dissipation: CRCW120623K2FKEAHP provides 0.75W rating with pulse withstanding capability while maintaining all other electrical parameters. This variant is suitable when thermal margin improvement is required without changing package footprint.

For New Designs: Avoid ERJ-8ENF2322V, which carries "Not For New Designs" status despite current inventory availability.

For Moisture-Resistant Applications: AC1206FR-0723K2L, RC1206FR-0723K2L, RK73H2BTTD2322F, and CR1206-FX-2322ELF explicitly include moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1206FR-0723K2L for AC1206FR-0723K2L? A: Yes. Both parts share identical electrical specifications (23.2 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and 1206 package. The primary difference is that RC1206FR-0723K2L does not carry AEC-Q200 automotive certification. Substitution is valid for non-automotive applications or where automotive certification is not contractually required.

Q: What is the difference between CRCW120623K2FKEA and CRCW120623K2FKEAHP? A: Both parts are manufactured by Vishay Dale with identical resistance, tolerance, temperature coefficient, and operating range. CRCW120623K2FKEAHP provides enhanced power rating (0.75W vs. 0.25W) and pulse withstanding capability. Mechanical dimensions differ slightly (height: 0.024" vs. 0.030"). CRCW120623K2FKEAHP is suitable for applications requiring higher thermal performance.

Q: Are all substitute parts available in the same packaging format? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, matching the original AC1206FR-0723K2L packaging.

Q: Can I use ERJ-8ENF2322V in a new design? A: No. ERJ-8ENF2322V carries "Not For New Designs" product status. While electrically equivalent and currently in stock, this part is designated for legacy support only. Select from active-status alternatives for new designs.

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: What is the mechanical compatibility between substitute parts? A: All substitute parts use the 1206 (3216 Metric) package. Dimensional variations exist within acceptable PCB footprint tolerances: length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations do not affect standard PCB assembly processes or component placement.
