AF1206FR-0747KL Equivalent & Substitute Parts

Part Overview

The AF1206FR-0747KL is a 47 kOhms ±1% 0.25W (1/4W) 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 1084 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements necessitate alternative manufacturers or enhanced specifications such as higher power ratings or different packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1206FR-0747KL is determined by the following critical parameters:

• Resistance Value: Must be 47 kOhms
• Tolerance: Must be ±1%
• Package / Case: Must be 1206 (3216 Metric)
• Power Rating: 0.25W (1/4W) minimum; higher ratings are acceptable
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, manufacturer-specific features (anti-sulfur vs. moisture resistant), and product status are noted but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs)

AC1206FR-0747KL (YAGEO) and CRCW120647K0FKEA (Vishay Dale) are the preferred substitutes. Both parts maintain identical electrical specifications, AEC-Q200 automotive qualification, ROHS3 compliance, and active production status. AC1206FR-0747KL offers the same manufacturer continuity as the primary part. CRCW120647K0FKEA provides cross-manufacturer redundancy with equivalent performance characteristics.

Secondary Substitutes (Acceptable with Considerations)

RC1206FR-0747KL (YAGEO) is electrically and mechanically equivalent but lacks AEC-Q200 rating. This part is suitable for non-automotive applications where automotive qualification is not required. The alternative packaging format (Cut Tape & Digi-Reel®) may require process adjustments in automated assembly environments.

CR1206-FX-4702ELF (Bourns Inc.) meets all core electrical parameters and maintains ROHS3 compliance. Like RC1206FR-0747KL, it does not carry AEC-Q200 rating. Physical dimensions vary slightly within 1206 package tolerance.

Higher Power Rating Option

CRCW120647K0FKEAHP (Vishay Dale) provides 0.75W (3/4W) power rating in the same 1206 package with AEC-Q200 qualification and ROHS3 compliance. This part is suitable for applications requiring enhanced thermal performance or pulse withstanding capability.

Not Recommended for New Designs

ERJ-8ENF4702V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting electrical specifications and AEC-Q200 qualification. CRCW120647K0FKTA (Vishay Dale) is RoHS non-compliant and REACH-affected, making it unsuitable for applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can I substitute AF1206FR-0747KL with a part having a different power rating?

A: Yes, provided the substitute has equal or higher power rating. CRCW120647K0FKEAHP (0.75W) is a valid substitute for AF1206FR-0747KL (0.25W). Lower power ratings are not acceptable.

Q: Does the absence of AEC-Q200 rating disqualify a substitute?

A: No. AEC-Q200 is a qualification standard for automotive applications. Parts without this rating remain electrically and mechanically compatible for non-automotive use. For automotive applications, AEC-Q200 qualified parts are required.

Q: Are there packaging format differences between substitutes?

A: Yes. AF1206FR-0747KL is supplied in Tape & Reel (TR) format. RC1206FR-0747KL and CRCW120647K0FKEA use Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard SMD assembly equipment, though process parameters may require adjustment.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer is phasing out the part. While ERJ-8ENF4702V remains functionally equivalent, it should not be selected for new product designs due to potential future unavailability.

Q: Can I use CRCW120647K0FKTA as a substitute?

A: CRCW120647K0FKTA is electrically compatible but is RoHS non-compliant and REACH-affected. Use only in applications where environmental compliance is not required or mandated.

Q: How do I verify physical compatibility in my PCB layout?

A: All listed substitutes use the 1206 (3216 Metric) package. Verify footprint dimensions in your design files. Minor variations in length, width, and height exist within package tolerance but do not affect PCB pad layout compatibility.
