RC3216F4420CS Equivalent & Substitute Parts

Part Overview

The RC3216F4420CS is a 442 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film, moisture-resistant component operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Equivalent and substitute parts are necessary to address supply chain continuity, inventory management, and design flexibility across multiple manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F4420CS is determined by strict equivalence across the following parameters: resistance value (442 Ohms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99). All substitute parts listed maintain these core electrical and mechanical specifications.

Substitute parts are classified into two categories:

Direct Substitutes maintain identical specifications across all parameters: CR1206-FX-4420ELF (Bourns Inc.), RC1206FR-07442RL (YAGEO), and ERJ-8ENF4420V (Panasonic Electronic Components).

Similar Substitutes introduce additional features or enhanced ratings while maintaining core compatibility: CRCW1206442RFKEA (Vishay Dale) adds Automotive AEC-Q200 certification at the same 0.25W power rating, and CRCW1206442RFKEAHP (Vishay Dale) provides enhanced pulse withstanding capability at 0.75W power rating with AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CR1206-FX-4420ELF (Bourns Inc.) and RC1206FR-07442RL (YAGEO) are direct functional equivalents to the RC3216F4420CS. Both parts maintain identical electrical specifications, package dimensions, and regulatory compliance. Both manufacturers are active in production and suitable for new designs.

For Automotive Applications: CRCW1206442RFKEA (Vishay Dale) is the appropriate selection when Automotive AEC-Q200 qualification is required. This part maintains the 0.25W power rating and all other core specifications while adding automotive-grade reliability certification.

For Enhanced Power Dissipation: CRCW1206442RFKEAHP (Vishay Dale) provides increased power handling at 0.75W with pulse withstanding capability and AEC-Q200 certification. This part is suitable for applications requiring higher transient power dissipation while maintaining the 1206 package footprint.

Avoid for New Designs: ERJ-8ENF4420V (Panasonic Electronic Components) carries a "Not For New Designs" product status. While electrically and mechanically compatible, this part should not be selected for new product development. Existing designs using this part may continue to source it for production support.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4420ELF replace RC3216F4420CS in existing designs?

A: Yes. CR1206-FX-4420ELF is a direct substitute with identical resistance, tolerance, power rating, package, and operating temperature specifications. Both parts are ROHS3 compliant with MSL 1 rating and maintain the same thermal and electrical characteristics.

Q: What is the difference between CRCW1206442RFKEA and CRCW1206442RFKEAHP?

A: CRCW1206442RFKEA is rated at 0.25W power dissipation, matching the original RC3216F4420CS specification. CRCW1206442RFKEAHP is rated at 0.75W with pulse withstanding capability. Both carry AEC-Q200 automotive certification. Selection depends on application power requirements.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist in maximum seated height across manufacturers. RC3216F4420CS specifies 0.026" (0.66mm), CR1206-FX-4420ELF specifies 0.030" (0.75mm), RC1206FR-07442RL specifies 0.026" (0.65mm), CRCW1206442RFKEA specifies 0.024" (0.60mm), CRCW1206442RFKEAHP specifies 0.026" (0.65mm), and ERJ-8ENF4420V specifies 0.028" (0.70mm). All parts fit the 1206 package standard and are suitable for standard PCB assembly processes.

Q: Why is ERJ-8ENF4420V marked "Not For New Designs"?

A: ERJ-8ENF4420V carries a "Not For New Designs" product status from Panasonic Electronic Components. This designation indicates the manufacturer is not recommending this part for new product development. Existing production designs may continue to use this part, but new designs should select from active-status alternatives.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed substitute parts carry MSL 1 (Unlimited) moisture sensitivity rating, identical to the RC3216F4420CS. This rating indicates no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: Which substitute part should be selected for automotive applications?

A: CRCW1206442RFKEA or CRCW1206442RFKEAHP (both Vishay Dale) are appropriate for automotive applications. Both carry AEC-Q200 certification. Select CRCW1206442RFKEA for standard 0.25W applications or CRCW1206442RFKEAHP for applications requiring 0.75W power rating with pulse withstanding capability.
