RC3216F4320CS: 432 Ohm 1% 1/4W 1206 Chip Resistor

Part Overview

The RC3216F4320CS is a 432 Ohm thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 metric) package with ±1% tolerance and 0.25W power rating. The component features moisture-resistant construction and operates across the industrial temperature range of -55°C to 155°C. This part is currently in active production status. Equivalent and substitute parts are necessary to ensure design flexibility, accommodate supply chain variations, and support continuity of production when the primary component becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RC3216F4320CS is determined by matching the following critical electrical and mechanical parameters:

• Resistance Value: 432 Ohms (exact match required)
• Tolerance: ±1% (defines circuit accuracy capability)
• Power Rating: 0.25W / 1/4W (thermal handling requirement)
• Package Type: 1206 (3216 Metric) (PCB land pattern compatibility)
• Composition: Thick Film (manufacturing process equivalence)
• Temperature Coefficient: ±100ppm/°C (temperature stability requirement)
• Operating Temperature Range: -55°C to 155°C (environmental operating limits)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

All five qualified substitutes meet these mandatory electrical specifications and package requirements. Substitution may be further influenced by product status (active vs. not for new designs) and optional certifications such as automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

Five manufacturers offer qualifying substitutes with identical electrical specifications. Four alternatives maintain active product status: CR1206-FX-4320ELF (Bourns), RC1206FR-07432RL (YAGEO), RMCF1206FT432R (Stackpole), and CRCW1206432RFKEA (Vishay Dale). These components are suitable for new designs and ongoing production.

Automotive-Qualified Alternatives:

Three substitutes carry automotive AEC-Q200 certification: ERJ-8ENF4320V (Panasonic), RMCF1206FT432R (Stackpole), and CRCW1206432RFKEA (Vishay Dale). These options are required for applications subject to automotive industry reliability and qualification standards.

Product Status Consideration:

ERJ-8ENF4320V (Panasonic ERJ-8EN series) carries a "Not For New Designs" status, indicating the manufacturer has classified this component as legacy. While electrically equivalent and functionally compatible, this part should not be selected for new product designs. It may be used only for legacy system maintenance or design continuity in existing products.

Height Variation:

Seated height specifications range from 0.024" to 0.030" (0.60mm to 0.75mm). The RC3216F4320CS reference part measures 0.026" (0.65mm), placing it within the mid-range of substitute heights. PCB design clearance must be verified if applications have restricted vertical space.

Frequently Asked Questions (FAQ)

Q: Are all listed substitutes electrically interchangeable with the RC3216F4320CS?

A: Yes. All five substitute parts match the critical electrical specifications: 432 Ohms resistance, ±1% tolerance, 0.25W power rating, and ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. Direct substitution is supported without circuit redesign.

Q: What is the difference between "Direct" and "Similar" substitute classification?

A: All listed substitutes meet identical electrical and mechanical parameters required for the 1206 package and 432 Ohm, ±1% specification. Classification differences reflect inventory status and supplier data structures but do not affect electrical equivalence.

Q: Why should ERJ-8ENF4320V be avoided for new designs?

A: Panasonic has designated the ERJ-8EN series with a "Not For New Designs" status, indicating the manufacturer is phasing out this product line. New product development should select alternatives with active product status to ensure long-term availability and supply continuity.

Q: Does the height variation between 0.024" and 0.030" affect PCB compatibility?

A: The 0.006" (0.15mm) maximum height difference may be significant in applications with restricted vertical clearance or tight component stacking. PCB design clearance requirements must be reviewed. The RC3216F4320CS at 0.026" is compatible with all substitutes within standard PCB manufacturing tolerances.

Q: Which substitutes carry automotive certification?

A: ERJ-8ENF4320V (Panasonic), RMCF1206FT432R (Stackpole), and CRCW1206432RFKEA (Vishay Dale) are qualified to AEC-Q200 automotive reliability standards. These are required for automotive applications. Non-automotive qualified substitutes (Bourns CR1206-FX-4320ELF and YAGEO RC1206FR-07432RL) are suitable for industrial and commercial applications.

Q: Is moisture sensitivity a concern for these components?

A: All parts, including the reference RC3216F4320CS, carry MSL-1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special environmental controls.
