Substitute Part Grouping Explanation

Substitute parts for the RMCS1206FT3R00 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 3 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitutes meet these core electrical and mechanical specifications. Variations in features (such as automotive qualification or moisture resistance enhancements) do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RMCS1206FT3R00, AC1206FR-073RL, and RC1206FR-073RL—are functionally equivalent for applications requiring a 3 Ohm ±1% 1/4W 1206 thick film resistor. Selection among these parts may be based on:

• Availability and inventory levels
• Supply chain lead times
• Manufacturer preference or qualification requirements
• Application-specific certifications (AC1206FR-073RL includes AEC-Q200 automotive qualification)
• Cost considerations

All parts maintain Active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory compatibility across standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-073RL replace RMCS1206FT3R00 in non-automotive applications?

A: Yes. AC1206FR-073RL meets all electrical and mechanical specifications of RMCS1206FT3R00. The automotive AEC-Q200 qualification is an additional feature that does not restrict use in standard applications.

Q: Are there dimensional differences between these parts?

A: All parts use the 1206 (3216 Metric) package. Minor variations in width (1.55mm vs 1.60mm) and height (0.65mm maximum) are within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction (RMCS1206FT3R00) and moisture-resistant construction (AC1206FR-073RL, RC1206FR-073RL) are different protective features. Both are thick film resistors with MSL 1 rating. Feature selection depends on environmental exposure requirements; both are suitable for standard operating conditions.

Q: Can these parts be used interchangeably in production?

A: Yes, provided design documentation and procurement specifications permit multi-source qualification. All parts share identical electrical parameters (3 Ohms ±1%, 0.25W, ±200ppm/°C, -55°C ~ 155°C) and package specifications.

Q: Are there inventory considerations for these substitutes?

A: Inventory levels vary by supplier and manufacturer. RC1206FR-073RL shows higher stock availability (53,645 pcs), while RMCS1206FT3R00 and AC1206FR-073RL have lower current inventory. Procurement strategy should account for lead times and supply continuity requirements.
