Parts are grouped into two categories based on power rating compatibility:

Primary Substitutes (0.25W / 1/4W): AC1206FR-0782RL, RC1206FR-0782RL, CR1206-FX-82R0ELF, CRCW120682R0FKEA, ERJ-8ENF82R0V, RC3216F820CS

Extended Rating Substitute (0.75W / 3/4W): CRCW120682R0FKEAHP — acceptable where higher power dissipation margin is required

Intermediate Rating Substitute (0.5W / 1/2W): ESR18EZPF82R0 — acceptable where moderate power margin is needed

Engineering Selection Recommendations

Preferred Substitutes (Direct Replacement): AC1206FR-0782RL, RC1206FR-0782RL, CRCW120682R0FKEA, and CR1206-FX-82R0ELF are functionally equivalent to AF1206FR-0782RL. All maintain identical electrical specifications, power rating, and operating temperature range. All are ROHS3 compliant and carry MSL 1 rating. Selection among these options should be based on availability and supply chain considerations.

Conditional Substitutes: CRCW120682R0FKEAHP (0.75W) and ESR18EZPF82R0 (0.5W) are acceptable where circuit design permits higher power dissipation margins. These parts maintain all other electrical and mechanical parameters.

Legacy Status: ERJ-8ENF82R0V carries "Not For New Designs" status. Use only when existing inventory must be consumed or when design revision is not feasible. Transition to active-status alternatives for new production.

Frequently Asked Questions (FAQ)

Q: Can CRCW120682R0FKEAHP (0.75W) replace AF1206FR-0782RL (0.25W)? A: Yes. The higher power rating provides additional thermal margin and does not degrade circuit performance. The part is mechanically and electrically compatible across all other parameters.

Q: Is ERJ-8ENF82R0V suitable for new designs? A: No. This part carries "Not For New Designs" status. Use AC1206FR-0782RL, RC1206FR-0782RL, or CRCW120682R0FKEA for new production.

Q: Do all substitutes meet automotive AEC-Q200 requirements? A: AC1206FR-0782RL, CRCW120682R0FKEA, CRCW120682R0FKEAHP, ERJ-8ENF82R0V, and ESR18EZPF82R0 carry AEC-Q200 qualification. RC1206FR-0782RL, CR1206-FX-82R0ELF, and RC3216F820CS do not list AEC-Q200 in their specifications. Verify compliance requirements before selection.

Q: Are there dimensional differences between substitutes? A: All parts use 1206 (3216 Metric) package designation. Minor height variations exist (0.024" to 0.030" seated height). Verify PCB assembly equipment compatibility if height-critical applications are involved.

Q: What is the difference between AF, AC, and RC series from YAGEO? A: AF series includes anti-sulfur properties. AC series includes moisture-resistant properties. RC series includes moisture-resistant properties. All three are YAGEO 1206 thick film resistors with identical electrical specifications for this 82Ω ±1% application.

Q: Can I use ESR18EZPF82R0 (0.5W) instead of the 0.25W rated part? A: Yes. The intermediate power rating provides thermal margin while maintaining all electrical and mechanical compatibility. This is a valid substitution path.
