AC2010JK-071ML Equivalent & Substitute Parts

Part Overview

The AC2010JK-071ML is a 1 MOhm ±5% 0.75W thick film chip resistor in 2010 (5025 Metric) package manufactured by YAGEO. This automotive-grade component features AEC-Q200 qualification and moisture resistance, designed for high-reliability applications in temperature ranges from -55°C to 155°C. The part is currently active in production with 803 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand higher tolerance specifications, or when alternative manufacturers' components offer improved lead times or inventory availability while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the AC2010JK-071ML is determined by strict equivalence in the following parameters:

Resistance value: 1 MOhms (exact match required)
Power rating: 0.75W (exact match required)
Package: 2010 (5025 Metric) (exact match required)
Operating temperature range: -55°C to 155°C (exact match required)
Composition: Thick Film (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: MSL 1 (exact match required)

Tolerance may vary (±5% or ±1%) without affecting substitution eligibility, as tighter tolerance specifications represent functional upgrades. Automotive AEC-Q200 qualification is preserved across all listed substitutes. All substitute parts are supplied in Tape & Reel (TR) packaging.

Engineering Selection Recommendations

Primary Substitutes (Automotive AEC-Q200 Qualified, Active Status):

AC2010FK-071ML (YAGEO) and CRGCQ2010J1M0 (TE Connectivity) are direct functional equivalents with identical electrical specifications. AC2010FK-071ML offers tighter ±1% tolerance within the same YAGEO series. CRGCQ2010J1M0 provides significantly higher inventory availability (106,911 units) from an alternative qualified manufacturer.

Secondary Substitutes (Automotive AEC-Q200 Qualified, Active Status):

CRCW20101M00FKEF (Vishay Dale) and RMCF2010FT1M00 (Stackpole Electronics) are qualified alternatives with ±1% tolerance and extensive inventory. Both manufacturers maintain active production status and full ROHS3 compliance.

Alternative Substitutes (Non-Automotive Qualified):

RC2010JK-071ML and RC2010FK-071ML (YAGEO RC_L series) are functionally equivalent but lack AEC-Q200 automotive qualification. These parts are suitable only for non-automotive applications requiring the same electrical and mechanical specifications.

Obsolescence Consideration:

ERJ-12SF1004U (Panasonic) carries "Not For New Designs" status and should be avoided for new product development, though it remains available in inventory (14,035 units) for legacy system support.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-071ML replace AC2010JK-071ML in automotive applications?

A: Yes. AC2010FK-071ML is a direct substitute with identical package, power rating, operating temperature range, and AEC-Q200 qualification. The only difference is tighter tolerance (±1% versus ±5%), which represents a functional upgrade.

Q: What is the difference between YAGEO AC series and RC series resistors?

A: The AC series includes automotive AEC-Q200 qualification; the RC series does not. Both share identical electrical and mechanical specifications (1 MOhm, 0.75W, 2010 package, ±100ppm/°C). RC series parts are suitable only for non-automotive applications.

Q: Are all substitute parts available in 2010 package?

A: Yes. All listed substitutes use the 2010 (5025 Metric) package with identical dimensions (0.197" L × 0.098" W, 5.00mm × 2.50mm) and maximum seated height of 0.026" to 0.028".

Q: Why is ERJ-12SF1004U marked "Not For New Designs"?

A: This Panasonic part is in end-of-life status. While electrically and mechanically equivalent, it should not be selected for new product designs. Use CRCW20101M00FKEF, RMCF2010FT1M00, or CRGCQ2010J1M0 instead.

Q: Do all substitutes meet ROHS3 compliance?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

Q: Can I use a ±1% tolerance part where ±5% is specified?

A: Yes. Tighter tolerance specifications are functionally superior and directly interchangeable. AC2010FK-071ML, CRCW20101M00FKEF, ERJ-12SF1004U, and RMCF2010FT1M00 all provide ±1% tolerance as upgrades to the ±5% specification.

Q: Which substitute offers the best inventory availability?

A: CRCW20101M00FKEF (Vishay Dale) has the highest inventory at 209,225 units, followed by CRGCQ2010J1M0 (TE Connectivity) at 106,911 units.
