Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Equivalence Parameters:

Resistance value: 1 kOhms (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Termination count: 2 (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Composition: Thick Film (exact match required)

Tolerance Variants: Parts with ±1% tolerance are considered upgrades to the ±5% specification and are functionally compatible for applications where tighter tolerance is acceptable or beneficial.

Power Rating Variants: Parts rated at 0.75W (3/4W) are considered upgrades to the 0.25W specification and provide enhanced thermal margin.

Feature Variants: Anti-sulfur coating, automotive AEC-Q200 qualification, and moisture-resistant properties are application-specific features. Parts with these features removed or replaced with alternative features remain electrically equivalent if all primary parameters match.

Packaging Format: Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats are interchangeable for component selection purposes; format selection depends on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can AF1206JR-071KL be replaced with a ±1% tolerance part? A: Yes. Parts with ±1% tolerance (AF1206FR-071KL, AC1206FR-071KL, RC1206FR-071KL, CR1206-FX-1001ELF, CRCW12061K00FKEA) are functionally compatible. Tighter tolerance provides improved accuracy and is acceptable in applications designed for ±5% parts.

Q: What is the difference between packaging formats (Tape & Reel vs. Cut Tape)? A: Tape & Reel (TR) format is supplied on continuous reel for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® format is supplied in tape segments for lower-volume or mixed-component assembly. Electrical and mechanical specifications are identical; selection depends on assembly process requirements.

Q: Are YAGEO AF, AC, and RC series parts interchangeable? A: Yes, when electrical parameters match. AF series emphasizes anti-sulfur coating. AC series emphasizes moisture resistance. RC series is standard thick film. All three series from YAGEO meet the same electrical specifications for equivalent part numbers.

Q: Can CRCW12061K00FKEAHP (0.75W) replace AF1206JR-071KL (0.25W)? A: Yes. The 0.75W rating is a performance upgrade that provides additional thermal margin. The part occupies the same 1206 package footprint and maintains all other electrical parameters. This substitution is suitable for applications where enhanced power dissipation capability is beneficial or required.

Q: What does AEC-Q200 qualification mean? A: AEC-Q200 is an automotive qualification standard. Parts with this rating meet automotive reliability and performance requirements. AF1206JR-071KL, AC series, and CRCW series carry AEC-Q200 qualification. RC series and CR1206 series do not carry this rating but remain functionally equivalent for non-automotive applications.

Q: Are all listed parts ROHS3 compliant? A: Yes. All parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements.
