RCS3216F9531CS Equivalent & Substitute Parts

Part Overview

The RCS3216F9531CS is a 9.53 kOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across the temperature range of -55°C to 155°C. The part is currently active in production with 782 pieces available in stock. Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for alternative qualified components meeting identical electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the RCS3216F9531CS is determined by strict equivalence across the following critical parameters: resistance value (9.53 kOhms), tolerance (±1%), power rating (0.25W), package type (1206/3216 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical specifications and physical package dimensions. Substitutes are grouped by manufacturer and product status, with variations noted in secondary features such as automotive qualification (AEC-Q200) and specific moisture-resistant properties. The 1206 package footprint and two-terminal configuration remain constant across all alternatives, ensuring mechanical and electrical compatibility in PCB assembly applications.

Engineering Selection Recommendations

Active Production Parts: CR1206-FX-9531ELF (Bourns), CRCW12069K53FKEA (Vishay Dale), and RC1206FR-079K53L (YAGEO) are all active products suitable for new designs. These three alternatives provide the highest long-term availability and supply chain stability.

Automotive-Qualified Options: CRCW12069K53FKEA and ERJ-8ENF9531V carry AEC-Q200 automotive qualification. These parts are appropriate for applications requiring automotive-grade reliability standards.

Inventory Availability: RC1206FR-079K53L (YAGEO) offers the largest inventory position at 120,073 pieces, followed by CR1206-FX-9531ELF (Bourns) at 25,963 pieces. These options provide superior supply security for high-volume procurement.

Obsolescence Consideration: ERJ-8ENF9531V is marked "Not For New Designs" and should be avoided in new product development, though it remains available for legacy system support or maintenance applications.

Compliance: All listed alternatives maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity), matching the original part's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly for the RCS3216F9531CS without design changes?

A: Yes. All listed substitute parts maintain identical electrical specifications (9.53 kOhms ±1%, 0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 1206 package footprint. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the main part and the substitutes?

A: The primary differences are manufacturer identity and secondary features. The Samsung part includes anti-sulfur properties. Vishay Dale and Panasonic parts include AEC-Q200 automotive qualification. Bourns and YAGEO parts feature standard moisture resistance. All core electrical and thermal parameters are identical.

Q: Should I use ERJ-8ENF9531V in a new design?

A: No. ERJ-8ENF9531V is marked "Not For New Designs." This designation indicates the manufacturer is phasing out this product line. Use this part only for legacy system maintenance or repair applications where the original part number is required.

Q: Which substitute offers the best supply availability?

A: RC1206FR-079K53L from YAGEO provides the largest inventory at 120,073 pieces, offering superior supply security for high-volume applications.

Q: Are there package dimension variations I should consider?

A: Minor variations exist in seated height: RCS3216F9531CS (0.66mm), CR1206-FX-9531ELF (0.75mm), CRCW12069K53FKEA (0.60mm), ERJ-8ENF9531V (0.70mm), and RC1206FR-079K53L (0.65mm). All remain within acceptable 1206 package specifications and do not affect PCB assembly compatibility.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. All carry MSL Level 1 (unlimited moisture sensitivity), matching the original part's regulatory and environmental status.
