Substitute Part Grouping Explanation

Substitute parts for the AC1206JR-0782KL are grouped into two categories based on tolerance specifications:

Category 1: Direct Tolerance Match (±5%) Parts maintaining ±5% tolerance provide direct electrical equivalence without design modification. These parts are interchangeable in applications where the original tolerance specification is required.

Category 2: Upgraded Tolerance (±1%) Parts with ±1% tolerance offer improved accuracy compared to the original specification. These parts are electrically compatible and may be substituted when tighter tolerance requirements are beneficial to circuit performance. Substitution requires verification that the circuit design does not depend on the original ±5% tolerance specification.

Key Parameters Determining Substitution:

Resistance value: 82 kOhms (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Power rating: 0.25W minimum (equal or higher acceptable)
Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C

Engineering Selection Recommendations

Primary Substitutes (Active Status, AEC-Q200 Qualified): AC1206FR-0782KL, CRCW120682K0FKEA, and KTR18EZPF8202 are recommended as primary substitutes. These parts maintain active product status, AEC-Q200 automotive qualification matching the original part, and are available in high inventory quantities. AC1206FR-0782KL provides direct YAGEO series continuity with upgraded ±1% tolerance. CRCW120682K0FKEA and KTR18EZPF8202 offer cross-manufacturer alternatives with equivalent automotive certifications.

Secondary Substitutes (Active Status, Non-AEC-Q200): RC1206FR-0782KL and CR1206-FX-8202ELF are suitable for applications where AEC-Q200 qualification is not required. Both maintain active product status and ±1% tolerance specification.

Legacy Substitutes (Not For New Designs): ERJ-8ENF8202V is classified as "Not For New Designs" and should be used only in legacy system maintenance or repair applications where original part sourcing is unavailable.

Higher Power Rating Option: CRCW120682K0FKEAHP provides 0.75W power rating in the same 1206 package, suitable for applications requiring increased power dissipation capability while maintaining all other electrical and compliance specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute AC1206JR-0782KL with a ±1% tolerance part? A: Yes. Parts with ±1% tolerance (AC1206FR-0782KL, RC1206FR-0782KL, CR1206-FX-8202ELF, CRCW120682K0FKEA, ERJ-8ENF8202V, KTR18EZPF8202) are electrically compatible. The tighter tolerance provides improved accuracy and does not create incompatibility with circuits designed for ±5% tolerance.

Q: Does the package dimension variation affect substitution? A: All substitute parts use the 1206 (3216 Metric) package. Minor dimensional variations (length 0.122" to 0.126", height 0.024" to 0.030") are within standard PCB footprint tolerances and do not affect mechanical or electrical compatibility.

Q: Is AEC-Q200 qualification required for my application? A: AEC-Q200 qualification is mandatory for automotive applications. For non-automotive applications, parts without AEC-Q200 rating (RC1206FR-0782KL, CR1206-FX-8202ELF) are acceptable. Verify application requirements before substitution.

Q: Can I use CRCW120682K0FKEAHP (0.75W) instead of the 0.25W original part? A: Yes. Higher power rating components are backward compatible in circuits designed for lower power ratings. The 0.75W part provides additional thermal margin and is suitable for applications with higher power dissipation requirements.

Q: Why is ERJ-8ENF8202V marked "Not For New Designs"? A: This part is in legacy status and may have limited future availability. For new designs, select from active status alternatives: AC1206FR-0782KL, RC1206FR-0782KL, CR1206-FX-8202ELF, CRCW120682K0FKEA, CRCW120682K0FKEAHP, or KTR18EZPF8202.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original AC1206JR-0782KL specifications.
