Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT64R9 is determined by strict equivalence across the following parameters:

• Resistance value: 64.9 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in additional features (automotive AEC-Q200 certification, moisture resistance enhancements) do not disqualify substitution but may be relevant for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement with no additional design constraints, AC1206FR-0764R9L, CR1206-FX-64R9ELF, and RC1206FR-0764R9L are suitable alternatives, all carrying Active product status.

For automotive applications or designs requiring AEC-Q200 qualification, AC1206FR-0764R9L and CRCW120664R9FKEA are qualified options with Active status. CRCW120664R9FKEA offers the highest inventory availability (19,419 units).

ERJ-8ENF64R9V carries Not For New Designs status and should be avoided in new product development despite its large inventory position (195,090 units). This part is suitable only for legacy system maintenance or existing design continuations.

All substitute parts maintain identical electrical specifications (64.9 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and RoHS3 compliance. Physical dimension variations within the 1206 package envelope do not affect PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMCS1206FT64R9 with any of the listed parts without PCB redesign?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical electrical specifications. Minor physical dimension variations (length, width, height) remain within standard 1206 package tolerances and do not require PCB footprint modification.

Q: What is the difference between parts with "Automotive AEC-Q200" and those without?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. AC1206FR-0764R9L and CRCW120664R9FKEA carry this certification; RMCS1206FT64R9, CR1206-FX-64R9ELF, and RC1206FR-0764R9L do not. Selection depends on application requirements.

Q: Why is ERJ-8ENF64R9V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for new applications. While electrically equivalent and currently in stock, it should not be selected for new product designs. Use only for legacy system support.

Q: Are moisture-resistant variants interchangeable with the standard RMCS1206FT64R9?

A: Yes. Moisture resistance is an additional feature that does not affect electrical performance or package compatibility. CR1206-FX-64R9ELF, AC1206FR-0764R9L, and RC1206FR-0764R9L provide enhanced moisture protection without changing substitution eligibility.

Q: What does "Anti-Sulfur" on the RMCS1206FT64R9 mean for substitution?

A: Anti-sulfur protection is a manufacturing feature of the Stackpole part. Substitute parts do not explicitly list this feature but maintain equivalent performance across all specified electrical and environmental parameters. Selection of alternatives should be based on application environment requirements.
