Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

Resistance Value: Must be 6.2 Ohms
Package Type: Must be 1206 (3216 Metric)
Composition: Must be Thick Film
Temperature Coefficient: Must be ±200ppm/°C
Operating Temperature Range: Must be -55°C to 155°C
RoHS Compliance: Must be ROHS3 Compliant
Moisture Sensitivity: Must be MSL 1

Tolerance and power rating variations are permitted within the substitute list. Tolerance can be ±1% or ±5%. Power rating can be 0.25W or 0.5W, provided the higher rating does not create mechanical incompatibility. Automotive AEC-Q200 rating is maintained across all substitutes.

Engineering Selection Recommendations

All listed substitute parts maintain full compatibility with the AF1206JR-076R2L in terms of package footprint, thermal characteristics, and compliance certifications. Selection among substitutes should be based on the following criteria:

For AEC-Q200 Automotive Applications: AC1206FR-076R2L, CRCW12066R20JNEA, ESR18EZPJ6R2, and RMCF1206FT6R20 all carry AEC-Q200 certification and are suitable for automotive environments.

For Tolerance-Critical Circuits: AC1206FR-076R2L, RMCF1206FT6R20, and RC1206FR-076R2L offer ±1% tolerance, providing tighter resistance control compared to the original ±5% specification.

For Higher Power Dissipation: ESR18EZPJ6R2 provides 0.5W rating, doubling the power capacity while maintaining the same package dimensions and thermal operating range.

For General-Purpose Substitution: RC1206JR-076R2L matches the original tolerance and power rating while offering alternative sourcing from YAGEO's RC_L series.

All parts are ROHS3 compliant, MSL 1 rated, and operate across the full -55°C to 155°C temperature range with ±200ppm/°C temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can I use a ±1% tolerance part as a direct substitute for the ±5% original?

A: Yes. The ±1% tolerance parts (AC1206FR-076R2L, RMCF1206FT6R20, RC1206FR-076R2L) are direct substitutes. Tighter tolerance provides improved circuit accuracy and is backward compatible with designs specified for ±5%.

Q: Is the ESR18EZPJ6R2 with 0.5W rating compatible with a 0.25W design?

A: Yes. The higher power rating does not create incompatibility. The 0.5W part will operate safely in circuits designed for 0.25W. Physical dimensions remain within 1206 package specifications.

Q: Which substitute should I use if AEC-Q200 certification is required?

A: AC1206FR-076R2L, CRCW12066R20JNEA, ESR18EZPJ6R2, and RMCF1206FT6R20 all carry AEC-Q200 certification. RC1206FR-076R2L and RC1206JR-076R2L do not have this rating.

Q: Are all substitutes available in the same packaging format?

A: Most substitutes are supplied in Tape & Reel (TR) format matching the original. ESR18EZPJ6R2 is supplied in Cut Tape (CT) format, which may affect procurement and handling procedures.

Q: Do all substitutes maintain the same temperature coefficient?

A: Yes. All listed substitutes maintain ±200ppm/°C temperature coefficient and operate across -55°C to 155°C, matching the original specification.

Q: Can I mix different manufacturers in the same production run?

A: Yes. All substitutes are ROHS3 compliant, MSL 1 rated, and meet the same electrical and mechanical specifications. Cross-manufacturer substitution is permissible from an engineering standpoint.
