Substitute Part Grouping Explanation

Substitute parts for the AF2010JK-072K2L are qualified based on the following critical parameters:

Resistance Value: 2.2 kOhms (exact match required)
Package / Case: 2010 (5025 Metric) (exact match required)
Power Rating: 0.75W minimum (exact match required)
Composition: Thick Film (exact match required)
Operating Temperature Range: -55°C ~ 155°C minimum (exact match required)
Terminations: 2 (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)
MSL Rating: 1 (Unlimited) (exact match required)

Tolerance variations (±5% vs ±1%) are permitted as substitute parts with tighter tolerance specifications maintain backward compatibility with the original ±5% requirement. Manufacturer differences and feature variations (anti-sulfur vs moisture resistant, automotive AEC-Q200 certification) do not affect electrical or mechanical substitution eligibility when all core parameters match.

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical compatibility with the AF2010JK-072K2L based on provided specifications. Selection among these alternatives should be based on:

RC2010FK-072K2L (YAGEO): Offers tighter ±1% tolerance specification with moisture-resistant thick film composition. Maintains identical package dimensions and thermal characteristics. 3980 units in stock.

RC2010JK-072K2L (YAGEO): Provides exact tolerance match (±5%) with moisture-resistant thick film composition. Identical electrical and mechanical specifications to the main part. 6767 units in stock.

CRCW20102K20FKEF (Vishay Dale): Delivers ±1% tolerance with automotive AEC-Q200 qualification matching the main part's automotive rating. Seated height specification is 0.028" (0.70mm) versus 0.026" (0.65mm) for YAGEO variants. 3950 units in stock.

All parts are ROHS3 compliant, carry MSL 1 (Unlimited) rating, and operate across the -55°C ~ 155°C temperature range. Product status is active for all alternatives.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072K2L replace AF2010JK-072K2L in automotive applications?

A: Yes. RC2010FK-072K2L maintains all critical electrical and mechanical parameters. The ±1% tolerance is tighter than the original ±5% specification, providing improved accuracy. Both parts are ROHS3 compliant with identical operating temperature ranges and package dimensions.

Q: What is the difference between the YAGEO and Vishay Dale options?

A: YAGEO variants (RC2010FK-072K2L and RC2010JK-072K2L) feature moisture-resistant thick film composition. CRCW20102K20FKEF from Vishay Dale carries automotive AEC-Q200 qualification like the original part. The Vishay part has a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.65mm) for YAGEO parts. All three maintain identical resistance, power rating, and package specifications.

Q: Are tolerance differences significant for substitution?

A: Tolerance differences do not prevent substitution. Parts with ±1% tolerance (RC2010FK-072K2L and CRCW20102K20FKEF) are backward compatible with designs specified for ±5% tolerance. The tighter tolerance provides improved circuit performance without requiring design modifications.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All substitute parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). The CRCW20102K20FKEF has a maximum seated height of 0.028" (0.70mm) versus 0.026" (0.65mm) for YAGEO variants. This 0.002" (0.05mm) difference is within standard PCB assembly tolerances and does not affect mechanical fit.

Q: What is the MSL rating and why does it matter?

A: MSL 1 (Unlimited) indicates these parts have unlimited shelf life and require no special moisture control during storage or handling. All substitute parts carry this rating, ensuring consistent handling requirements across alternatives.
