Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Resistance Value: Must be 3 kOhms
• Power Rating: Must be 0.5W (1/2W) minimum
• Package: Must be 1210 (3225 Metric)
• Temperature Range: Must support -55°C to 155°C
• Composition: Thick film construction
• Compliance: RoHS3 and MSL 1 required

Tolerance variations (±5% to ±1%) are permitted as tighter tolerances represent functional improvements. Automotive AEC-Q200 rating is maintained across primary substitutes. Packaging format (Tape & Reel or Cut Tape) does not affect electrical substitutability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility)

AC1210FR-073KL and CRCW12103K00FKEA are direct substitutes with improved tolerance (±1%) and maintained AEC-Q200 automotive qualification. Both support identical operating temperature ranges and package specifications. AC1210FR-073KL is YAGEO series with moisture-resistant features. CRCW12103K00FKEA is Vishay Dale series with equivalent automotive certification.

Secondary Substitutes (Tolerance Match)

RC1210JR-073KL maintains ±5% tolerance matching the original AF1210JR-073KL but removes AEC-Q200 automotive rating. This part is suitable for non-automotive applications within the same tolerance specification.

Tolerance-Improved Substitute (Non-Automotive)

RC1210FR-073KL offers ±1% tolerance improvement but lacks AEC-Q200 rating and automotive qualification. Selection depends on application requirements for automotive compliance.

All substitutes maintain RoHS3 compliance, MSL 1 rating, and identical thermal coefficients. Physical dimensions are compatible within 1210 package specifications.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-073KL replace AF1210JR-073KL in automotive applications?

A: Yes. AC1210FR-073KL maintains AEC-Q200 automotive qualification, identical resistance value, power rating, and operating temperature range. The ±1% tolerance is tighter than the original ±5%, which is functionally superior.

Q: What is the difference between YAGEO AF, AC, and RC series resistors?

A: AF series includes anti-sulfur construction with AEC-Q200 rating. AC series provides moisture-resistant thick film with AEC-Q200 rating. RC series offers moisture-resistant construction without automotive AEC-Q200 qualification. All three series support identical electrical parameters for this 3 kOhms value.

Q: Is CRCW12103K00FKEA compatible with the original part?

A: Yes. CRCW12103K00FKEA is a Vishay Dale equivalent with ±1% tolerance, AEC-Q200 rating, and identical package, resistance, and power specifications. Physical dimensions are within 1210 package tolerance (0.126" L x 0.098" W versus 0.122" L x 0.102" W).

Q: Can I use RC1210FR-073KL if automotive qualification is not required?

A: Yes. RC1210FR-073KL is electrically and mechanically compatible for non-automotive applications. It provides ±1% tolerance improvement over the original ±5% specification while maintaining identical power rating and operating temperature range.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect substitutability?

A: No. Packaging format affects handling and assembly logistics only. Electrical and mechanical specifications remain identical. AC1210FR-073KL and RC1210FR-073KL are supplied in Tape & Reel format; CRCW12103K00FKEA is available in Cut Tape & Digi-Reel format.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original AF1210JR-073KL specification.
