Substitute Part Grouping Explanation

Substitute parts for the RMCS1206FT27K4 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 27.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W, 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

All identified substitutes meet these core electrical and mechanical specifications. Dimensional variations within supplier tolerances and feature differences (Anti-Sulfur, Moisture Resistant, Automotive AEC-Q200) do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts meet the core electrical and mechanical specifications of the RMCS1206FT27K4. Selection among equivalents should be based on the following criteria:

CR1206-FX-2742ELF (Bourns Inc.) and CRCW120627K4FKEA (Vishay Dale) are both classified as Active product status and are suitable for new designs. CRCW120627K4FKEA carries Automotive AEC-Q200 certification, making it appropriate for automotive applications requiring this qualification.

ERJ-8ENF2742V (Panasonic Electronic Components) is classified as Not For New Designs and should be used only for legacy system maintenance or replacement applications where continuity with existing inventory is required.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-2742ELF be used as a direct replacement for RMCS1206FT27K4?

A: Yes. Both components share identical electrical specifications (27.4 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and package format (1206). Dimensional variations (0.122" vs 0.126" length, 0.061" vs 0.063" width) fall within standard supplier tolerances and do not affect PCB layout or circuit performance.

Q: Is CRCW120627K4FKEA suitable for automotive applications?

A: Yes. CRCW120627K4FKEA carries Automotive AEC-Q200 certification and meets all electrical and environmental specifications required for automotive use.

Q: Why is ERJ-8ENF2742V marked as Not For New Designs?

A: ERJ-8ENF2742V is classified as Not For New Designs by Panasonic Electronic Components. This designation indicates the manufacturer is phasing out this product line. It remains available for legacy system support and replacement applications but should not be selected for new product development.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the RMCS1206FT27K4.

Q: What is the difference between Anti-Sulfur and Moisture Resistant features?

A: Anti-Sulfur (RMCS1206FT27K4) and Moisture Resistant (CR1206-FX-2742ELF) are distinct protective features. Both provide environmental protection but address different degradation mechanisms. Selection depends on specific application environment requirements.
