Substitute Part Grouping Explanation

Substitution eligibility for the AF1210JR-072K7L is determined by the following critical parameters:

Resistance Value: Must be 2.7 kOhms
Package / Case: Must be 1210 (3225 Metric)
Power Rating: Must be 0.5W (1/2W)
Composition: Must be Thick Film
Temperature Coefficient: Must be ±100ppm/°C

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance. Selection between substitutes should be based on the following criteria:

RC1210FR-072K7L (YAGEO): Offers ±1% tolerance with moisture-resistant thick film composition. Suitable for applications requiring tighter tolerance specifications than the original ±5% specification. Available in Cut Tape and Digi-Reel packaging formats.

RC1210JR-072K7L (YAGEO): Maintains the original ±5% tolerance specification with moisture-resistant thick film composition. Functionally equivalent to the main part with identical electrical characteristics. Available in Cut Tape and Digi-Reel packaging formats.

CRCW12102K70FKEA (Vishay Dale): Provides ±1% tolerance with automotive AEC-Q200 qualification matching the original part's automotive rating. Dimensional variation exists (0.126" L x 0.098" W vs. 0.122" L x 0.102" W), requiring PCB layout verification. Available in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-072K7L replace AF1210JR-072K7L directly?

A: Yes. Both parts share identical resistance (2.7 kOhms), power rating (0.5W), package (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The RC1210FR-072K7L offers improved tolerance (±1% vs. ±5%) and moisture-resistant properties. Packaging format differs (Cut Tape vs. Tape & Reel), which does not affect electrical compatibility.

Q: What is the difference between RC1210JR-072K7L and RC1210FR-072K7L?

A: Both are YAGEO 1210 resistors with 2.7 kOhms resistance and 0.5W power rating. The primary difference is tolerance: RC1210JR-072K7L maintains ±5% tolerance (matching the original part), while RC1210FR-072K7L provides ±1% tolerance. Both feature moisture-resistant thick film composition.

Q: Is CRCW12102K70FKEA dimensionally compatible with AF1210JR-072K7L?

A: CRCW12102K70FKEA has slightly different dimensions (0.126" L x 0.098" W vs. 0.122" L x 0.102" W). Height remains identical at 0.024" (0.60mm). PCB layout and footprint spacing must be verified before substitution to ensure mechanical fit.

Q: Do all substitute parts meet automotive requirements?

A: AF1210JR-072K7L and CRCW12102K70FKEA both carry AEC-Q200 automotive qualification. RC1210FR-072K7L and RC1210JR-072K7L do not list AEC-Q200 rating; they feature moisture-resistant properties instead. For automotive applications requiring AEC-Q200 certification, use AF1210JR-072K7L or CRCW12102K70FKEA.

Q: What packaging formats are available?

A: AF1210JR-072K7L and CRCW12102K70FKEA are supplied in Tape & Reel (TR) format. RC1210FR-072K7L and RC1210JR-072K7L are supplied in Cut Tape (CT) and Digi-Reel® formats. Packaging format selection depends on assembly equipment and production volume requirements.
