RCS3216J472CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216J472CS is a 4.7 kOhms ±5% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant characteristics. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Power rating: 0.25W minimum (higher power ratings such as 0.333W or 0.75W are acceptable)
Temperature coefficient: ±100ppm/°C (standard for this category)
RoHS and MSL compliance: ROHS3 Compliant, MSL 1 (standard environmental requirements)

Feature Variations Permitted:

Automotive AEC-Q200 certification (enhancement, not requirement)

Engineering Selection Recommendations

Direct Substitutes (Identical Tolerance ±5%):

AC1206JR-074K7L (YAGEO) and RC1206JR-074K7L (YAGEO) are direct functional equivalents with matching ±5% tolerance and 0.25W power rating. Both parts maintain identical electrical and mechanical specifications. RC1206JR-074K7L offers significantly higher inventory availability (187,210 units) compared to the main part (1,145 units).

PCR1206-4K7J1 (Riedon) provides ±5% tolerance matching with increased power rating (0.333W) in the same 1206 package. This part is suitable for applications requiring higher pulse withstanding capability.

Tighter Tolerance Alternatives (±1%):

Multiple manufacturers offer ±1% tolerance variants suitable for applications requiring improved accuracy:

RC1206FR-074K7L (YAGEO): Highest inventory availability (1,000,400 units), Active product status, moisture-resistant thick film

Frequently Asked Questions (FAQ)

Q: Can I substitute a ±1% tolerance part for the ±5% RCS3216J472CS?

A: Yes. Tighter tolerance (±1%) is a functional enhancement and does not compromise circuit compatibility. The ±1% tolerance parts (RC1206FR-074K7L, AC1206FR-074K7L, CR1206-FX-4701ELF, CRCW12064K70FKEA, KTR18EZPF4701) are direct substitutes. Circuit performance will equal or exceed the original specification.

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" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations remain within standard 1206 package tolerances and do not affect PCB assembly or circuit function.

Q: Can I use PCR1206-4K7J1 with its 0.333W rating instead of 0.25W?

A: Yes. Higher power rating (0.333W vs. 0.25W) provides additional thermal margin and pulse withstanding capability. The part is electrically and mechanically compatible. Use this part when circuit conditions may approach or exceed the original 0.25W specification.

Q: Can I use CRCW12064K70FKEAHP with its 0.75W rating?

A: Yes. The 0.75W rating provides significant thermal margin above the 0.25W specification. This part is suitable for applications with higher power dissipation or stringent pulse immunity requirements. Mechanical compatibility is maintained within the 1206 package.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging is supplied in individual strips suitable for manual assembly or small-quantity applications. Tape & Reel packaging is supplied on continuous reels for automated pick-and-place assembly. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Are Automotive AEC-Q200 certified parts suitable for non-automotive applications?

A: Yes. Automotive AEC-Q200 certification indicates enhanced reliability testing and quality standards. These parts (AC1206FR-074K7L, AC1206JR-074K7L, CRCW12064K70FKEA, CRCW12064K70FKEAHP, ERJ-8ENF4701V, KTR18EZPF4701) are fully compatible with non-automotive applications and provide equivalent or superior performance.

Q: Why is ERJ-8ENF4701V marked "Not For New Designs"?

A: This status indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. While the part meets all electrical and mechanical specifications, long-term availability and supply chain continuity cannot be guaranteed. Select alternative Active-status parts for new designs.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-074K7L (YAGEO) provides the highest inventory availability at 1,000,400 units. This part combines ±1% tolerance, Active product status, and exceptional stock levels, making it suitable for high-volume production requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the environmental specifications of the main part RCS3216J472CS.
