RC3216F431CS Equivalent & Substitute Parts

Part Overview

The RC3216F431CS is a 430 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 1,037 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, design redundancy, and supply chain continuity when the primary part becomes unavailable or when design specifications permit upgraded alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across all critical electrical and mechanical parameters. All identified substitute parts match the RC3216F431CS in resistance value (430 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitutes maintain ROHS3 compliance and MSL 1 rating.

Substitutes are grouped into three categories based on additional features and product status:

Direct Equivalents - Parts with identical electrical specifications and standard industrial features. These include CR1206-FX-4300ELF (Bourns Inc.) and RC1206FR-07430RL (YAGEO). Both maintain moisture resistance and are in active production.

Upgrade Alternative - AC1206FR-07430RL (YAGEO) adds AEC-Q200 automotive qualification while maintaining all base electrical parameters. This part is suitable for applications requiring automotive-grade reliability.

Similar Alternatives - CRCW1206430RFKEA (Vishay Dale) and ERJ-8ENF4300V (Panasonic Electronic Components) include AEC-Q200 automotive qualification. ERJ-8ENF4300V carries "Not For New Designs" status, limiting its use to legacy system support or maintenance applications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC1206FR-07430RL (YAGEO) is the primary direct equivalent, offering the highest inventory availability (42,804 units) and active production status. CR1206-FX-4300ELF (Bourns Inc.) provides an alternative direct equivalent with adequate stock (17,375 units).

For Automotive and High-Reliability Applications: AC1206FR-07430RL (YAGEO) is the recommended upgrade path, adding AEC-Q200 automotive qualification while maintaining all base electrical specifications. CRCW1206430RFKEA (Vishay Dale) provides an alternative automotive-qualified option with 15,593 units in stock.

For Legacy System Maintenance Only: ERJ-8ENF4300V (Panasonic Electronic Components) carries "Not For New Designs" status and is restricted to replacement and maintenance applications for existing systems. Despite high inventory (56,464 units), this part should not be selected for new product development.

Moisture Sensitivity Consideration: CR1206-FX-4300ELF and RC1206FR-07430RL explicitly maintain moisture-resistant features matching the original RC3216F431CS. CRCW1206430RFKEA and ERJ-8ENF4300V do not specify moisture resistance; verify environmental requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F431CS with any of these parts directly on the PCB?

A: Yes, all listed substitutes share identical 1206 package dimensions and electrical specifications (430 Ω ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). Direct PCB footprint compatibility is confirmed. However, verify moisture resistance requirements for your application environment.

Q: What is the difference between direct equivalents and upgrade alternatives?

A: Direct equivalents (CR1206-FX-4300ELF, RC1206FR-07430RL) match all electrical and environmental specifications of the original part. Upgrade alternatives (AC1206FR-07430RL, CRCW1206430RFKEA, ERJ-8ENF4300V) add AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications requiring enhanced qualification testing.

Q: Why is ERJ-8ENF4300V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. ERJ-8ENF4300V remains available for legacy system maintenance and replacement applications only.

Q: Are all substitutes ROHS3 compliant?

A: Yes, all listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC3216F431CS regulatory status.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-07430RL (YAGEO) provides the highest stock level at 42,804 units, followed by ERJ-8ENF4300V (Panasonic) at 56,464 units. However, ERJ-8ENF4300V is restricted to legacy applications. For new designs, RC1206FR-07430RL is the optimal choice for supply continuity.

Q: Can I use automotive-qualified parts (AEC-Q200) in non-automotive applications?

A: Yes, automotive-qualified parts exceed standard industrial specifications and are fully compatible with non-automotive applications. AC1206FR-07430RL and CRCW1206430RFKEA can be used in any application where the base RC3216F431CS is specified, with no performance degradation.

Q: What are the physical dimension differences between substitutes?

A: All parts use 1206 package format with length 0.122" to 0.126" (3.10mm to 3.20mm) and width 0.063" (1.60mm). Height variations range from 0.024" to 0.030" (0.60mm to 0.75mm). These minor dimensional differences do not affect PCB assembly compatibility for standard 1206 footprints.
