Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

AC1206FR-0782KL and CRCW120682K0FKEA are the preferred substitutes. Both maintain AEC-Q200 automotive qualification, offer tighter ±1% tolerance, and are in active production status. AC1206FR-0782KL provides YAGEO continuity with moisture-resistant features. CRCW120682K0FKEA offers Vishay Dale reliability with automotive certification.

Secondary Substitutes (Active Production):

RC1206FR-0782KL, RC1206JR-0782KL, CR1206-FX-8202ELF, and KTR18EZPF8202 are functionally equivalent and in active production. These parts satisfy all mandatory parameters but may lack AEC-Q200 certification (RC series) or offer alternative feature sets (Bourns moisture resistance, Rohm high voltage capability).

Higher Power Alternative:

CRCW120682K0FKEAHP provides 0.75W power rating with AEC-Q200 qualification. This part is suitable when increased power dissipation capability is required within the same package footprint.

Legacy Status:

ERJ-8ENF8202V is marked "Not For New Designs" and should be avoided in new product development despite maintaining AEC-Q200 qualification and active inventory.

Frequently Asked Questions (FAQ)

Q: Can I substitute AF1206JR-0782KL with a part having ±1% tolerance?

A: Yes. Tighter tolerance (±1%) is an acceptable substitution parameter. Parts such as AC1206FR-0782KL, RC1206FR-0782KL, CRCW120682K0FKEA, ERJ-8ENF8202V, and KTR18EZPF8202 all provide ±1% tolerance while maintaining the 82 kOhms resistance value and 1206 package.

Q: Does the packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format is a manufacturing and handling consideration only. AC1206FR-0782KL uses Cut Tape & Digi-Reel® format while maintaining identical electrical specifications to Tape & Reel alternatives.

Q: Is AEC-Q200 certification required for substitution?

A: AEC-Q200 is not mandatory for electrical equivalence but is critical for automotive applications. The original AF1206JR-0782KL carries AEC-Q200 certification. For automotive designs, substitute with AC1206FR-0782KL, CRCW120682K0FKEA, CRCW120682K0FKEAHP, ERJ-8ENF8202V, or KTR18EZPF8202 to maintain certification compliance.

Q: Can I use CRCW120682K0FKEAHP (0.75W) as a direct replacement for AF1206JR-0782KL (0.25W)?

A: Yes. Higher power rating is an acceptable substitution parameter. The 0.75W rating provides additional thermal margin and is electrically compatible with circuits designed for 0.25W components.

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

A: This designation indicates the part is in legacy status. While currently in stock and functionally equivalent, Panasonic recommends using active production alternatives for new product development to ensure long-term availability and support.

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

A: AF series includes anti-sulfur coating with AEC-Q200 qualification. AC series provides moisture-resistant thick film with AEC-Q200 qualification. RC series offers moisture-resistant thick film without automotive certification. All three series maintain identical electrical parameters for the 82 kOhms ±5% or ±1% values.
