RCS3216F3830CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F3830CS is a 383 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3830CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Resistance value: 383 Ohms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
RoHS compliance: ROHS3
Moisture sensitivity: MSL 1

All four substitute parts listed meet these mandatory criteria. Variations in physical dimensions (length and height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and optional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but represent secondary differentiators for specific application requirements.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC1206FR-07383RL (YAGEO) and RC1206FR-07383RL (YAGEO) are both active products with identical electrical specifications to the RCS3216F3830CS. AC1206FR-07383RL carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. RC1206FR-07383RL provides equivalent performance without automotive certification. Both are available in high inventory quantities.

CRCW1206383RFKEA (Vishay Dale) is an active product with AEC-Q200 automotive qualification and the highest available inventory (22,246 pcs). This part offers the lowest maximum seated height (0.024") among all substitutes, which may be advantageous in space-constrained PCB layouts.

Secondary Substitute (Not For New Designs):

ERJ-8ENF3830V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable only for legacy system maintenance, repair, or continuation of existing production runs where design changes are not permitted. New designs should not incorporate this part number.

Selection Criteria:

For new designs and standard applications, select from AC1206FR-07383RL, RC1206FR-07383RL, or CRCW1206383RFKEA based on supply availability and packaging preference. For automotive applications, AC1206FR-07383RL or CRCW1206383RFKEA are required due to AEC-Q200 certification. For space-constrained designs, CRCW1206383RFKEA offers the minimum height profile.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07383RL be used as a direct replacement for RCS3216F3830CS?

A: Yes. Both parts share identical electrical specifications (383 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C operating range) and package format (1206/3216 Metric). The AC1206FR-07383RL includes AEC-Q200 automotive qualification, which is an additional feature not present in the RCS3216F3830CS but does not prevent substitution. Physical dimensions are within acceptable tolerance for standard PCB layouts.

Q: What is the difference between AC1206FR-07383RL and RC1206FR-07383RL?

A: Both are YAGEO 1206 resistors with identical electrical performance. AC1206FR-07383RL carries AEC-Q200 automotive qualification and is specified as "Automotive AEC-Q200, Moisture Resistant." RC1206FR-07383RL is specified as "Moisture Resistant" without automotive certification. Selection depends on whether automotive-grade reliability is required for the application.

Q: Why is ERJ-8ENF3830V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While the part meets all technical specifications and remains available in inventory, it should not be selected for new product designs. It is reserved for maintenance and repair of existing systems already using this component.

Q: Are there physical dimension differences that affect PCB layout?

A: Yes, minor variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126" and height from 0.024" to 0.028". These variations are within standard 1206 package tolerances and do not affect PCB footprint design. However, in space-constrained applications, CRCW1206383RFKEA (0.024" max height) offers the lowest profile option.

Q: What packaging formats are available?

A: Substitute parts are available in Tape & Reel (TR) format, which is standard for automated assembly. CRCW1206383RFKEA is also available in Cut Tape (CT) & Digi-Reel® format for smaller quantity requirements. Packaging format does not affect electrical or mechanical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (AC1206FR-07383RL, CRCW1206383RFKEA, ERJ-8ENF3830V, and RC1206FR-07383RL) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the RCS3216F3830CS specification.

Q: Which substitute offers the best inventory availability?

A: CRCW1206383RFKEA (Vishay Dale) has the highest inventory level at 22,246 pcs. RC1206FR-07383RL (YAGEO) is also well-stocked at 106,852 pcs. Both represent reliable long-term supply options.
