Substitute Part Grouping Explanation

Substitute parts for AC1206JR-07910KL are qualified based on the following criteria:

Electrical Parameters (Must Match):

Resistance value: 910 kOhms
Power rating: 0.25W (1/4W)
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

Package type: 1206 (3216 Metric)
Composition: Thick Film
Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

RoHS3 Compliant
MSL 1 (Unlimited)
Automotive AEC-Q200 qualification

Tolerance Consideration: The main part specifies ±5% tolerance. Substitute parts with ±1% tolerance provide tighter tolerance and are functionally compatible for applications where the original ±5% specification is acceptable. Parts with ±5% tolerance provide direct equivalence.

Engineering Selection Recommendations

Direct Equivalents (Recommended for Replacement):

RC1206JR-07910KL (YAGEO): Identical tolerance (±5%), same manufacturer, Active status. Suitable for direct substitution in existing designs.
CRCW1206910KFKEA (Vishay Dale): Maintains AEC-Q200 automotive qualification with ±1% tolerance, Active status. Recommended for automotive applications requiring higher tolerance precision.
KTR18EZPF9103 (Rohm Semiconductor): AEC-Q200 qualified with ±1% tolerance and high voltage capability, Active status. Suitable for automotive and industrial applications.

Higher Tolerance Precision Options:

RC1206FR-07910KL (YAGEO): ±1% tolerance, Active status. Provides tighter tolerance specification while maintaining YAGEO manufacturer continuity.
CR1206-FX-9103ELF (Bourns Inc.): ±1% tolerance, Active status. Cross-manufacturer option with established reliability.

Legacy Status (Not Recommended for New Designs):

ERJ-8ENF9103V (Panasonic Electronic Components): Marked "Not For New Designs" despite AEC-Q200 qualification and Active inventory. Use only for maintenance or repair of existing equipment.

Frequently Asked Questions (FAQ)

Q: Can I substitute AC1206JR-07910KL with a ±1% tolerance part? A: Yes. Parts with ±1% tolerance (RC1206FR-07910KL, CR1206-FX-9103ELF, CRCW1206910KFKEA, KTR18EZPF9103) are functionally compatible. The ±1% tolerance is tighter than the original ±5% specification and will not cause circuit incompatibility. Verify circuit design requirements before substitution.

Q: Are all substitute parts automotive-qualified? A: No. Only AC1206JR-07910KL, CRCW1206910KFKEA, ERJ-8ENF9103V, and KTR18EZPF9103 carry AEC-Q200 automotive qualification. For automotive applications, select from these four options.

Q: What is the difference between RC1206JR-07910KL and RC1206FR-07910KL? A: Both are YAGEO RC series resistors in 1206 package with 910 kOhms resistance. RC1206JR-07910KL has ±5% tolerance (matching the original part), while RC1206FR-07910KL has ±1% tolerance. Both are Active status and suitable for substitution.

Q: Why is ERJ-8ENF9103V marked "Not For New Designs"? A: This designation indicates the part is in legacy status. While inventory is available and the part meets all electrical and mechanical specifications, Panasonic recommends using alternative sources for new product designs. Use only for maintenance or repair applications.

Q: Are there physical dimension differences between substitute parts? A: All parts use 1206 (3216 Metric) package with identical length (0.122" to 0.126" L) and width (0.063" W). Height variations range from 0.024" to 0.030" seated maximum. These minor dimensional differences do not affect PCB footprint compatibility or soldering process.

Q: Do all substitute parts meet RoHS3 and MSL 1 requirements? A: Yes. All listed substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original AC1206JR-07910KL specification.

Q: Which substitute offers the best availability? A: CRCW1206910KFKEA (Vishay Dale) has 20,570 units in stock, and ERJ-8ENF9103V (Panasonic) has 41,732 units. Both provide high availability with automotive qualification.
