RCS3216F4750CS 475 Ohm 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RCS3216F4750CS is a 475 Ohm thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.25W (1/4W) in a 1206 (3216 Metric) surface mount package. This component features anti-sulfur and moisture-resistant construction with ±1% tolerance and ±100ppm/°C temperature coefficient, suitable for general industrial and commercial applications operating between -55°C and 155°C.

The part is currently in active production status with 1,044 pieces available in inventory. Equivalent and substitute parts are identified based on matching electrical specifications (475 Ohms ±1%, 0.25W power rating), mechanical package dimensions (1206), and environmental operating parameters. Substitutes may vary in manufacturing features, automotive certifications, and packaging formats while maintaining functional equivalence.

Engineering Selection Recommendations

Primary Recommendation for New Designs: CRCW1206475RFKEA (Vishay Dale) is the preferred substitute for new product development. This part maintains full ROHS3 compliance, active production status, automotive AEC-Q200 certification, and the highest inventory availability (17,568 pieces). The part is electrically and mechanically identical to the RCS3216F4750CS with matching dimensional specifications.

Alternative Selections Based on Availability: RMCF1206FT475R (Stackpole Electronics Inc) offers the largest inventory stock (87,292 pieces) with equivalent specifications, ROHS3 compliance, and active production status. This part is suitable for high-volume applications requiring extended lead-time protection.

Automotive Applications: AC1206FR-07475RL (YAGEO) and RMCF1206FT475R both carry AEC-Q200 automotive certification, making them suitable for automotive-grade circuit designs while maintaining full compatibility with the original RCS3216F4750CS specification.

Obsolescence Consideration: ERJ-8ENF4750V (Panasonic Electronic Components) carries "Not For New Designs" status despite high inventory availability. This part should be used only for legacy system maintenance or repair applications where design continuity is required.

Compliance Exception: CRCW1206475RFKTA (Vishay Dale) is RoHS non-compliant and REACH-affected. This part is not suitable for applications requiring regulatory compliance and should be avoided for new designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206475RFKEAHP (0.75W variant) be used as a substitute for the RCS3216F4750CS (0.25W)?

A: No. The CRCW1206475RFKEAHP is rated at 0.75W (3/4W) power dissipation, which differs from the 0.25W specification of the RCS3216F4750CS. Although both use the 1206 package and share identical resistance and tolerance values, the power rating is a non-substitutable parameter. Using a higher-rated component may mask thermal design issues and is not equivalent.

Q: Are there dimensional differences between substitute parts that affect PCB layout?

A: All listed substitutes use the 1206 (3216 Metric) package with identical PCB footprints. Physical dimensions vary slightly within manufacturing tolerance (length 3.10mm to 3.20mm, height 0.60mm to 0.75mm), but these variations are within standard 1206 package specifications and do not require PCB redesign.

Q: Which substitute offers the best lead-time security?

A: RMCF1206FT475R (Stackpole Electronics Inc) provides the highest inventory buffer with 87,292 pieces in stock. CRCW1206475RFKEA (Vishay Dale) offers the second-best availability at 17,568 pieces. Both parts are in active production with ROHS3 compliance.

Q: Is the ERJ-8ENF4750V suitable for new product designs?

A: No. The ERJ-8ENF4750V carries "Not For New Designs" product status, indicating that Panasonic has discontinued active development for this part. Although electrically equivalent and currently in inventory, this part should be reserved for legacy system repairs only. Use CRCW1206475RFKEA or RMCF1206FT475R for new designs.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging is supplied in smaller quantities on cut segments of the same carrier tape. Both formats contain identical components; packaging selection depends on assembly volume and equipment compatibility. RMCF1206FT475R is available in Cut Tape & Digi-Reel format, while most other substitutes use standard Tape & Reel.

Q: Do automotive-certified parts (AEC-Q200) work in non-automotive applications?

A: Yes. Automotive AEC-Q200 certification indicates enhanced reliability testing and stricter quality standards. Parts certified to AEC-Q200 are fully compatible with non-automotive applications and provide additional reliability margin. AC1206FR-07475RL, CRCW1206475RFKEA, CRCW1206475RFKTA, ERJ-8ENF4750V, and RMCF1206FT475R all carry AEC-Q200 certification.

Q: Why is CRCW1206475RFKTA not recommended despite being in active production?

A: CRCW1206475RFKTA is RoHS non-compliant and REACH-affected, failing to meet current regulatory requirements for most commercial and industrial applications. Although electrically identical to the RCS3216F4750CS, its non-compliant status makes it unsuitable for new designs and many procurement specifications that mandate ROHS3 compliance.

Q: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All listed substitutes meet identical electrical and mechanical specifications. Mixing manufacturers on the same PCB is acceptable from a functional standpoint. However, procurement and quality assurance practices may require consistency within a single production batch for traceability and warranty purposes.
