RMCS1206FT47R0 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT47R0 is a 47 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur resistor is designed for general-purpose applications requiring stable resistance values across industrial temperature ranges. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements call for enhanced features such as automotive qualification or increased power ratings while maintaining the same electrical and mechanical footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT47R0 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 47 Ohms
• Tolerance: ±1%
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Power rating of 0.25W (1/4W) is the baseline requirement. Parts with equal or higher power ratings (0.75W) remain mechanically and electrically compatible within the same package footprint.

All substitute parts listed maintain these core parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in feature sets (automotive qualification, pulse withstanding capability, moisture resistance enhancements) do not affect substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

AC1206FR-0747RL (YAGEO), CR1206-FX-47R0ELF (Bourns Inc.), CRCW120647R0FKEA (Vishay Dale), and RC1206FR-0747RL (YAGEO) are direct electrical and mechanical equivalents with active product status. These parts maintain identical electrical specifications and are suitable for new designs and production applications.

Enhanced Power Rating Option:

CRCW120647R0FKEAHP (Vishay Dale) provides 0.75W power rating within the same 1206 package footprint. This part is electrically and mechanically compatible and offers increased thermal headroom for applications requiring higher transient power dissipation.

Automotive-Qualified Alternatives:

AC1206FR-0747RL, CRCW120647R0FKEA, CRCW120647R0FKEAHP, and ERJ-8ENF47R0V carry AEC-Q200 automotive qualification. These parts are suitable for automotive and high-reliability applications.

Legacy Status:

ERJ-8ENF47R0V (Panasonic Electronic Components) is marked "Not For New Designs." While electrically and mechanically equivalent, this part should be avoided for new product development. Existing designs using this part may continue with current inventory, but migration to active alternatives is recommended for long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher power rating (0.75W) in place of the 0.25W RMCS1206FT47R0?

A: Yes. The CRCW120647R0FKEAHP (0.75W) maintains the same 1206 package footprint, resistance value, tolerance, and temperature coefficient. Higher power rating provides additional thermal margin and does not create compatibility issues in the same PCB layout.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel packaging, maintaining consistency with the original RMCS1206FT47R0 packaging format.

Q: What is the difference between standard and automotive-qualified versions?

A: Automotive-qualified parts (AC1206FR-0747RL, CRCW120647R0FKEA, CRCW120647R0FKEAHP, ERJ-8ENF47R0V) carry AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. These parts are suitable for automotive applications and high-reliability environments. Non-automotive versions are suitable for general industrial and consumer applications.

Q: Why is ERJ-8ENF47R0V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and promotion of this part. While existing inventory may be available and the part remains electrically and mechanically equivalent, new designs should select from active alternatives to ensure long-term supply availability and manufacturer support.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126", width from 0.061" to 0.063", and height from 0.024" to 0.030". These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility or component placement.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All substitute parts carry Moisture Sensitivity Level 1 (Unlimited), matching the RMCS1206FT47R0. This rating indicates no moisture-related handling restrictions during storage, transport, or assembly.
