RC3216F4423CS 442 kOhm 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC3216F4423CS is a 442 kOhm thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package format. This component operates at 0.25W (1/4W) power rating with ±1% tolerance and moisture-resistant construction. The part maintains Active product status with 805 units currently in stock.

Substitute parts become necessary when primary inventory is depleted, when supply chain constraints affect availability, or when design requirements mandate alternative manufacturer certifications such as automotive AEC-Q200 qualification. Equivalent parts must maintain identical electrical specifications and mechanical compatibility to ensure direct circuit board substitution without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F4423CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Resistance value: 442 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Non-Negotiable):

• Package format: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All substitute parts listed maintain 100% compliance with these parameters. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances do not affect substitutability. Packaging format (Tape & Reel vs. bulk) represents a logistics distinction only and does not impact electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for New Designs): RC1206FR-07442KL (YAGEO) is the preferred substitute. This part maintains Active product status, ensuring long-term availability and continued manufacturer support. Electrical and mechanical specifications are identical to the RC3216F4423CS. The RC_L series provides equivalent moisture-resistant thick film construction with standard industrial certification.

Secondary Substitute (Automotive Applications): CRCW1206442KFKEA (Vishay Dale) is suitable when AEC-Q200 automotive qualification is required. This part carries Active product status and meets automotive reliability standards. Use this substitute only when the application circuit board or system design explicitly requires automotive-grade component certification.

Tertiary Substitute (Legacy Systems Only): ERJ-8ENF4423V (Panasonic Electronic Components) carries "Not For New Designs" product status. This part is electrically and mechanically equivalent but should not be selected for new circuit designs or long-term production programs. Existing designs currently using this component may continue with this part, but migration to RC1206FR-07442KL or CRCW1206442KFKEA is recommended for future production runs.

All three substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC3216F4423CS specification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07442KL replace RC3216F4423CS in existing circuit boards? A: Yes. Both parts are 1206 (3216 Metric) package format with identical electrical specifications (442 kOhms, ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C). Physical dimensions vary within standard manufacturing tolerances but do not affect PCB footprint compatibility or soldering process.

Q: What is the difference between standard and AEC-Q200 rated resistors? A: AEC-Q200 certification indicates the component meets automotive industry reliability and qualification standards. CRCW1206442KFKEA and ERJ-8ENF4423V carry this rating. Standard parts like RC3216F4423CS and RC1206FR-07442KL do not carry automotive certification. Select AEC-Q200 parts only when the application requires automotive-grade components.

Q: Why is ERJ-8ENF4423V marked "Not For New Designs"? A: This designation indicates the manufacturer (Panasonic) is phasing out this product line. While the part remains electrically and mechanically equivalent, it should not be selected for new circuit designs or production programs. Existing designs may continue using this part, but new designs should specify RC1206FR-07442KL or CRCW1206442KFKEA.

Q: Are there differences in packaging between these parts? A: RC3216F4423CS is supplied in standard packaging. RC1206FR-07442KL, CRCW1206442KFKEA, and ERJ-8ENF4423V are supplied in Tape & Reel (TR) format. This represents a logistics and handling distinction only. Electrical and mechanical specifications are identical. Tape & Reel packaging is standard for high-volume production environments.

Q: Can I use these parts interchangeably on the same PCB? A: Yes, all four parts are direct substitutes. They share identical 1206 package format, footprint compatibility, and electrical specifications. No circuit design changes are required. Soldering parameters and reflow profiles remain unchanged.

Q: Which substitute should I specify for a new design? A: For standard industrial applications, specify RC1206FR-07442KL (YAGEO). For automotive applications, specify CRCW1206442KFKEA (Vishay Dale). Both parts carry Active product status and ensure long-term availability. Avoid ERJ-8ENF4423V for new designs.
