AC2010FK-0723K7L Equivalent & Substitute Parts

Part Overview

The AC2010FK-0723K7L is a 23.7 kOhms ±1% thick film chip resistor manufactured by YAGEO in the 2010 (5025 Metric) package format. Rated for 0.75W power dissipation with automotive AEC-Q200 qualification and moisture resistance, this component is designed for automotive and industrial applications requiring high reliability. The part is currently active in production with 914 units in stock. Substitute parts may be required due to supply constraints, lead time considerations, or design flexibility across qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the AC2010FK-0723K7L is determined by strict equivalence across the following critical parameters:

• Resistance value: 23.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Package format: 2010 (5025 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)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed below meet these criteria and are functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AC2010FK-0723K7L (YAGEO), CRCW201023K7FKEF (Vishay Dale), and RMCF2010FT23K7 (Stackpole)—are electrically and mechanically equivalent and carry active product status with full AEC-Q200 automotive qualification and ROHS3 compliance.

Selection between these parts should be based on:

• Supply availability and lead time requirements
• Procurement cost and volume pricing
• Existing supplier relationships and qualification documentation
• PCB layout constraints, noting the maximum seated height variation of 0.002" (0.05mm) between YAGEO and the Vishay/Stackpole alternatives

The YAGEO AC2010FK-0723K7L features a lower maximum seated height of 0.026" compared to 0.028" for both substitute options. This minor dimensional difference is within standard PCB assembly tolerances but should be verified if height-constrained applications are involved.

Frequently Asked Questions (FAQ)

Q: Can CRCW201023K7FKEF or RMCF2010FT23K7 be used as direct replacements for AC2010FK-0723K7L?

A: Yes. Both parts meet all electrical and mechanical specifications, including resistance value, tolerance, power rating, package format, temperature range, and automotive AEC-Q200 qualification. They are functionally interchangeable at the component level.

Q: What is the significance of the height difference between AC2010FK-0723K7L (0.026") and the substitute parts (0.028")?

A: The 0.002" (0.05mm) difference falls within standard PCB assembly tolerances. However, in applications with tight vertical clearance constraints, this variation should be evaluated against board design specifications and assembly equipment capabilities.

Q: Are all three parts RoHS compliant?

A: Yes. AC2010FK-0723K7L, CRCW201023K7FKEF, and RMCF2010FT23K7 are all ROHS3 compliant with MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions.

Q: Do these parts require different handling or storage procedures?

A: No. All three parts carry MSL 1 rating, meaning they have unlimited moisture sensitivity and require no special desiccant storage or baking procedures prior to assembly.

Q: Which substitute part has the best availability?

A: CRCW201023K7FKEF (Vishay Dale) has the highest inventory at 5075 units, followed by RMCF2010FT23K7 (Stackpole) at 3306 units, compared to 914 units for the YAGEO AC2010FK-0723K7L.
