Part Overview

The AF2010JK-071ML is a 1 MOhms ±5% 0.75W thick film chip resistor in 2010 (5025 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 and features anti-sulfur construction. The part is currently active in production with 945 pieces in stock. Equivalent and substitute parts are identified based on matching electrical specifications, package dimensions, and compliance ratings to support design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Resistance value: 1 MOhms (exact match required)
Power rating: 0.75W (exact match required)
Package: 2010 (5025 Metric) (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
RoHS and MSL compliance: ROHS3 Compliant, MSL 1 (exact match required)

Tolerance variations (±5% vs ±1%) and feature differences (anti-sulfur vs moisture resistant) do not prevent substitution when all primary electrical and mechanical parameters align. Automotive AEC-Q200 rating is maintained across all qualified substitutes.

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement with the AF2010JK-071ML. Selection should prioritize parts with Active product status for new designs.

AC2010FK-071ML, CRCW20101M00FKEF, and RMCF2010FT1M00 are recommended as primary substitutes. These parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. AC2010FK-071ML offers the advantage of same-manufacturer sourcing from YAGEO with improved tolerance (±1%).

RC2010FK-071ML and RC2010JK-071ML are functionally compatible but lack explicit AEC-Q200 designation in the provided specifications. These parts remain suitable for applications where automotive qualification is not a design requirement.

ERJ-12SF1004U is available in high inventory but carries a "Not For New Designs" status. This part is suitable only for legacy system support or maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-071ML replace AF2010JK-071ML directly?

A: Yes. Both parts share identical resistance (1 MOhms), power rating (0.75W), package (2010), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The tolerance difference (±1% vs ±5%) represents improved accuracy and does not prevent substitution. Both maintain AEC-Q200 automotive qualification.

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

A: The AF series features anti-sulfur construction. The AC series includes moisture-resistant thick film with ±1% tolerance. The RC series offers moisture-resistant thick film without explicit AEC-Q200 designation. All three series use identical 2010 package dimensions and electrical specifications for the 1 MOhms 0.75W value.

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

A: This designation indicates the part is in mature or declining production status. While electrically and mechanically compatible, Panasonic recommends using alternative sources for new product development. The part remains available for existing applications and maintenance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes carry ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, matching the original AF2010JK-071ML specification.

Q: Can I use CRCW20101M00FKEF from Vishay Dale as a substitute?

A: Yes. The Vishay Dale CRCW20101M00FKEF meets all electrical and mechanical requirements, maintains AEC-Q200 qualification, and is actively produced with high inventory availability (209,225 pieces). The maximum seated height is 0.028" (0.70mm) compared to 0.026" (0.65mm) for the original part; this minor dimensional difference does not affect PCB layout compatibility for standard 2010 package footprints.

Q: What is the inventory status of substitute parts?

A: AC2010FK-071ML (6,287 pcs), RC2010FK-071ML (8,200 pcs), RC2010JK-071ML (4,300 pcs), CRCW20101M00FKEF (209,225 pcs), ERJ-12SF1004U (14,035 pcs), and RMCF2010FT1M00 (14,311 pcs) are all available in stock.
