AF1206FR-072K05L Equivalent & Substitute Parts

Part Overview

The AF1206FR-072K05L is a 2.05 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This thick film resistor 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 1,073 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the AF1206FR-072K05L is determined by the following critical parameters:

Resistance value: 2.05 kOhms
Tolerance: ±1%
Power rating: 0.25W minimum
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Automotive qualification: AEC-Q200
RoHS compliance: ROHS3

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances do not affect substitutability. Differences in specific features (anti-sulfur vs. moisture resistant) represent alternative coating technologies that do not compromise functional equivalence.

Engineering Selection Recommendations

For new designs and active production, RC1206FR-072K05L (YAGEO) and CRCW12062K05FKEA (Vishay Dale) are preferred substitutes. Both parts maintain active product status, full AEC-Q200 automotive qualification, and ROHS3 compliance. These options provide the highest availability and supply chain stability.

CRCW12062K05FKEAHP (Vishay Dale) is suitable as a substitute when circuit design permits higher power dissipation capability (0.75W vs. 0.25W). This part maintains all other electrical and compliance requirements while offering enhanced thermal performance.

ERJ-8ENF2051V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries "Not For New Designs" status. This part is acceptable only for legacy system maintenance or repair applications where supply of active alternatives is unavailable.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-072K05L replace AF1206FR-072K05L in automotive applications?

A: Yes. Both parts are 1206 package, 2.05 kOhms ±1%, 0.25W thick film resistors with identical temperature coefficients and operating ranges. RC1206FR-072K05L is ROHS3 compliant. The primary difference is coating technology (moisture resistant vs. anti-sulfur), which does not affect functional equivalence in automotive AEC-Q200 applications.

Q: What is the difference between CRCW12062K05FKEA and CRCW12062K05FKEAHP?

A: Both are Vishay Dale 1206 package resistors with 2.05 kOhms ±1% resistance. The key difference is power rating: CRCW12062K05FKEA is rated 0.25W, while CRCW12062K05FKEAHP is rated 0.75W with pulse withstanding capability. CRCW12062K05FKEAHP can be used as a substitute when circuit design allows higher power dissipation.

Q: Why is ERJ-8ENF2051V marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While it meets all electrical and mechanical specifications for the AF1206FR-072K05L, it should not be selected for new product development. Use active alternatives (RC1206FR-072K05L or CRCW12062K05FKEA) for new designs.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the primary part's packaging format for automated assembly compatibility.

Q: Do physical dimension variations affect substitutability?

A: No. All parts conform to 1206 (3216 Metric) package standard. Minor variations in length, width, and height (within standard tolerances) do not affect PCB footprint compatibility or functional performance.
