AF1206FR-0782KL Equivalent & Substitute Parts

Part Overview

The AF1206FR-0782KL is an 82 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for applications requiring reliability in harsh environments. The part is currently active in production with 718 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for equivalent components from qualified manufacturers that meet identical electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the AF1206FR-0782KL is determined by strict equivalence across the following parameters:

Resistance value: 82 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package designation: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
RoHS and environmental compliance: ROHS3 Compliant, MSL 1

All listed substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package tolerance, packaging format (Tape & Reel vs. Cut Tape), and specific feature sets (anti-sulfur, moisture resistant, high voltage, pulse withstanding) do not affect functional equivalence for circuit applications.

Engineering Selection Recommendations

For new designs and production applications, select from parts with Active product status: AC1206FR-0782KL, RC1206FR-0782KL, CR1206-FX-8202ELF, CRCW120682K0FKEA, CRCW120682K0FKEAHP, or KTR18EZPF8202. All maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The CRCW120682K0FKEAHP variant offers increased power rating (0.75W) while maintaining identical resistance, tolerance, and package specifications. This part is suitable for applications requiring higher pulse withstanding capability without circuit redesign.

The ERJ-8ENF8202V is marked "Not For New Designs" and should be used only for legacy system maintenance or existing production continuity where design changes are not feasible.

Packaging format selection (Tape & Reel vs. Cut Tape & Digi-Reel) depends on assembly equipment compatibility and production volume requirements. AC1206FR-0782KL offers Cut Tape and Digi-Reel options for lower-volume or manual assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW120682K0FKEAHP (0.75W) be used as a direct replacement for AF1206FR-0782KL (0.25W)?

A: Yes. The 0.75W part is electrically and mechanically equivalent. Higher power rating provides additional thermal margin and does not affect circuit function when the original 0.25W specification is met. Physical dimensions remain within 1206 package tolerance.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel is used for lower volumes, manual assembly, or mixed-component orders. Electrical and mechanical specifications are identical; packaging format affects only handling and dispensing during manufacturing.

Q: Are all substitute parts AEC-Q200 qualified?

A: All listed parts except RC1206FR-0782KL carry explicit AEC-Q200 automotive qualification. RC1206FR-0782KL does not list AEC-Q200 in its feature set but meets all electrical and mechanical equivalence criteria. Verify AEC-Q200 requirement with design specifications before selection.

Q: Why is ERJ-8ENF8202V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part series. It remains available for existing production support but should not be selected for new circuit designs. Use active alternatives from YAGEO, Bourns, Vishay Dale, or Rohm Semiconductor.

Q: Do physical dimension variations within the 1206 package affect PCB layout?

A: No. All parts conform to 1206 (3216 Metric) package specification. Minor variations in length (0.122" to 0.126"), width (0.063"), and height (0.024" to 0.030") are within standard tolerance and do not require PCB redesign. Footprint compatibility is maintained across all listed substitutes.

Q: Can these parts be used interchangeably in automotive applications?

A: Parts with AEC-Q200 qualification (AF1206FR-0782KL, AC1206FR-0782KL, CRCW120682K0FKEA, CRCW120682K0FKEAHP, ERJ-8ENF8202V, KTR18EZPF8202) are qualified for automotive use. RC1206FR-0782KL lacks explicit AEC-Q200 designation; confirm suitability with design requirements before use in automotive circuits.
