Substitute Part Grouping Explanation

Substitute parts for the RMCS1206FT5R11 are qualified based on the following criteria:

• Identical resistance value: 5.11 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.25W (1/4W)
• Same package designation: 1206 (3216 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Equivalent compliance: RoHS3 Compliant, REACH Unaffected
• Equivalent MSL rating: 1 (Unlimited)

The RC1206FR-075R11L from YAGEO meets all specified electrical and mechanical parameters, differing only in surface treatment (moisture resistant versus anti-sulfur) and minor dimensional tolerance in width (1.60mm versus 1.55mm), both within acceptable substitution criteria for this component category.

Parameter Comparison

Engineering Selection Recommendations

The RC1206FR-075R11L qualifies as a direct substitute for the RMCS1206FT5R11 based on matching electrical specifications, identical package dimensions, and equivalent compliance certifications. Both components are active products with RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, supply chain requirements, and application-specific environmental conditions. The moisture-resistant surface treatment of the YAGEO part provides an alternative to the anti-sulfur treatment of the Stackpole part, with both suitable for standard industrial applications within the specified temperature and humidity ranges.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-075R11L replace RMCS1206FT5R11 in existing designs?

A: Yes. Both parts share identical electrical specifications (5.11 Ohms ±1%, 0.25W), package designation (1206), temperature coefficient (±200ppm/°C), and operating range (-55°C to 155°C). The components are mechanically and electrically interchangeable.

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

A: Anti-sulfur treatment protects against sulfur-containing atmospheric contaminants, while moisture-resistant treatment provides protection against humidity exposure. Both are surface treatments that do not affect the core electrical performance of the resistor.

Q: Are there dimensional differences between these parts?

A: The length and height are identical (0.122" L × 0.026" H). Width differs slightly: RMCS1206FT5R11 is 0.061" (1.55mm) and RC1206FR-075R11L is 0.063" (1.60mm). Both dimensions fall within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). ECCN and HTSUS classifications are identical.

Q: Which part should be selected for new designs?

A: Selection should be based on supply availability and application environment. Both parts are active products suitable for new designs. Verify current inventory and lead times with your component supplier.
