Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Resistance value: 2.2 Ohms (exact match required)
Power rating: 0.75W minimum (equal or higher acceptable)
Package: 2010 (5025 Metric) form factor (exact match required)
Temperature coefficient: ±200ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
RoHS and REACH compliance: ROHS3 Compliant, REACH Unaffected (maintained across all substitutes)
Moisture sensitivity: MSL 1 (Unlimited) (maintained across all substitutes)

Tolerance variations (±1% vs ±5%) and feature differences (AEC-Q200 automotive rating, pulse withstanding capability, moisture resistance) are permitted substitution parameters that may enhance circuit performance without compromising compatibility. Packaging format (Tape & Reel vs Cut Tape) does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the AC2010JK-072R2L. Selection criteria are based on product status, compliance certifications, and availability:

RC2010JK-072R2L (YAGEO) offers the highest inventory availability (29,100 pieces) with identical electrical specifications and RoHS3 compliance, suitable for high-volume production requirements where AEC-Q200 automotive qualification is not mandated.

RC2010FK-072R2L (YAGEO) provides improved tolerance performance (±1% vs ±5%) while maintaining identical thermal and environmental specifications, appropriate for precision circuit applications requiring tighter resistance control.

RK73B2HTTE2R2J (KOA Speer Electronics) and CRCW20102R20JNEF (Vishay Dale) both maintain AEC-Q200 automotive qualification matching the original part, with adequate inventory levels (5,050 and 4,701 pieces respectively) for automotive and industrial applications.

RPC2010JT2R20 (Stackpole Electronics) combines AEC-Q200 qualification with pulse withstanding capability, offering enhanced transient performance for circuits subject to voltage spikes or surge conditions.

All substitutes are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072R2L replace AC2010JK-072R2L in all applications?

A: RC2010FK-072R2L is electrically and mechanically compatible. The primary difference is improved tolerance (±1% vs ±5%), which enhances accuracy but does not create incompatibility. Applications requiring AEC-Q200 automotive qualification should note that RC2010FK-072R2L does not carry this rating.

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

A: Both series use identical 2010 package dimensions and thermal specifications. The AC series includes AEC-Q200 automotive qualification; the RC series does not. Tolerance and composition remain equivalent within specified parameters.

Q: Are packaging format differences (Tape & Reel vs Cut Tape) significant for substitution?

A: Packaging format affects handling and assembly logistics only. Electrical and mechanical properties remain identical. CRCW20102R20JNEF (Cut Tape & Digi-Reel) is fully compatible with Tape & Reel packaged alternatives.

Q: Which substitute offers the best value for automotive applications?

A: RK73B2HTTE2R2J (KOA Speer) and CRCW20102R20JNEF (Vishay Dale) both maintain AEC-Q200 qualification with strong inventory availability. RPC2010JT2R20 (Stackpole) adds pulse withstanding capability for surge-sensitive circuits.

Q: Can I use RC2010JK-072R2L as a direct replacement for AC2010JK-072R2L?

A: RC2010JK-072R2L is electrically and mechanically identical with significantly higher inventory (29,100 vs 977 pieces). The absence of AEC-Q200 rating is the only functional difference; applications not requiring automotive qualification can substitute without restriction.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates no moisture sensitivity. These components require no special moisture control during storage, handling, or assembly, simplifying logistics across all substitute options.
