AC1206JR-072ML Equivalent & Substitute Parts

Part Overview

The AC1206JR-072ML is a 2 MOhms ±5% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 standard with moisture resistance and operates across -55°C to 155°C. The part is currently active in production with 5,739 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when design requirements demand tighter tolerance specifications, or when alternative packaging formats are required for manufacturing optimization.

Substitute Part Grouping Explanation

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

Resistance Value: Must be 2 MOhms
Package Type: Must be 1206 (3216 Metric)
Power Rating: Must be 0.25W (1/4W)
Composition: Must be Thick Film
Temperature Coefficient: Must be ±100ppm/°C
Operating Temperature Range: Must be -55°C to 155°C
Termination Count: Must be 2

Tolerance variations (±5% vs ±1%) and packaging formats (Tape & Reel vs Cut Tape) do not prevent substitution but represent design trade-offs. Tolerance upgrades from ±5% to ±1% provide improved accuracy. Packaging format changes affect manufacturing processes but maintain electrical equivalence.

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance & Automotive Rating)

AC1206FR-072ML (YAGEO) is the direct upgrade path, offering ±1% tolerance while maintaining AEC-Q200 automotive qualification and ROHS3 compliance. This part provides improved accuracy with identical electrical and thermal characteristics.

Automotive-Qualified Alternatives

CRCW12062M00FKEA (Vishay Dale) and KTR18EZPF2004 (Rohm Semiconductor) both meet AEC-Q200 automotive requirements with ±1% tolerance and ROHS3 compliance. These parts are electrically equivalent and suitable for automotive applications requiring tighter tolerance specifications.

Non-Automotive Alternatives

RC1206FR-072ML and RC1206JR-072ML (YAGEO) and RCV12062M00FKEA (Vishay Dale) lack AEC-Q200 automotive certification. These parts are suitable only for non-automotive applications where automotive qualification is not required.

Obsolescence Consideration

ERJ-8ENF2004V (Panasonic) carries "Not For New Designs" status. While electrically equivalent and AEC-Q200 qualified, this part should not be selected for new designs due to its obsolescence trajectory.

RoHS Compliance Requirement

CRCW12062M00FKTA (Vishay Dale) is RoHS non-compliant and REACH-affected. This part must not be used in applications requiring RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can AC1206JR-072ML be replaced with a ±1% tolerance part?

A: Yes. Parts with ±1% tolerance (AC1206FR-072ML, RC1206FR-072ML, CRCW12062M00FKEA, ERJ-8ENF2004V, KTR18EZPF2004, RCV12062M00FKEA) are electrically compatible. The ±1% tolerance is tighter than the original ±5%, providing improved accuracy without affecting circuit functionality.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (Tape & Reel vs Cut Tape & Digi-Reel) affects manufacturing and handling processes but does not affect electrical performance. Selection depends on assembly equipment and procurement requirements.

Q: Which substitute parts maintain automotive AEC-Q200 qualification?

A: AC1206FR-072ML, CRCW12062M00FKEA, CRCW12062M00FKTA, ERJ-8ENF2004V, and KTR18EZPF2004 all carry AEC-Q200 automotive certification. RC1206FR-072ML, RC1206JR-072ML, and RCV12062M00FKEA do not.

Q: Is CRCW12062M00FKTA suitable for new automotive designs?

A: No. This part is RoHS non-compliant and REACH-affected, making it unsuitable for applications requiring RoHS3 compliance or modern automotive standards.

Q: Can ERJ-8ENF2004V be used in new product designs?

A: No. This part carries "Not For New Designs" status. While electrically equivalent and AEC-Q200 qualified, it should not be selected for new designs due to manufacturer obsolescence designation.

Q: What is the difference between KTR18EZPF2004 and other ±1% alternatives?

A: KTR18EZPF2004 includes high voltage capability as an additional feature. All other parameters (resistance, tolerance, power rating, package, temperature range, AEC-Q200 qualification) are identical to other ±1% alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: No. CRCW12062M00FKTA is RoHS non-compliant. All other listed substitutes are ROHS3 compliant.
