Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F4220CS is permissible when the following parameters remain constant across all candidate parts:

Critical Parameters (Must Match Exactly):

• Resistance value: 422 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Manufacturer identity
• Packaging format (Tape & Reel, Cut Tape, Digi-Reel)
• Minor dimensional tolerances within supplier specifications
• Product series designation
• Automotive qualification (AEC-Q200) when not required by original design

The three substitute parts listed below satisfy all critical parameters and are electrically and mechanically interchangeable with the RC3216F4220CS.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-07422RL (YAGEO) is the primary direct substitute for RC3216F4220CS. This part maintains Active product status, identical electrical specifications, and Tape & Reel packaging. YAGEO RC1206FR-07422RL demonstrates the highest inventory availability at 61,945 pieces, ensuring supply chain continuity. Dimensional variations (3.10mm L vs. 3.20mm L) remain within acceptable PCB layout tolerances for 1206 package footprints.

CRCW1206422RFKEA (Vishay Dale) serves as an alternative substitute with AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability. The Digi-Reel packaging option provides flexibility for automated assembly processes. Inventory availability of 4,700 pieces supports moderate-volume production requirements.

ERJ-8ENF4220V (Panasonic Electronic Components) is classified as Not For New Designs. While electrically and mechanically equivalent, this part should be used only for legacy system maintenance, repair, or replacement applications where design continuity with existing assemblies is required. The 23,491-piece inventory supports ongoing support for fielded equipment.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07422RL be used as a direct replacement for RC3216F4220CS in production assembly?

A: Yes. RC1206FR-07422RL meets all critical electrical and mechanical parameters. Both parts are 1206 package, 422 Ohm ±1%, 0.25W thick film resistors with identical temperature coefficients and operating ranges. The minor dimensional difference (3.10mm vs. 3.20mm length) is within standard 1206 package tolerance and does not affect PCB footprint compatibility.

Q: What is the difference between the packaging formats offered by these substitutes?

A: RC3216F4220CS and RC1206FR-07422RL are supplied in Tape & Reel (TR) format, standard for automated pick-and-place assembly. CRCW1206422RFKEA is available in Cut Tape (CT) and Digi-Reel® formats, providing options for manual assembly or specialized automated equipment. ERJ-8ENF4220V uses Tape & Reel format. Selection depends on assembly process requirements.

Q: Why is ERJ-8ENF4220V marked as Not For New Designs?

A: Panasonic has designated the ERJ-8EN series as Not For New Designs, indicating the manufacturer is transitioning this product line. While the part remains electrically and mechanically equivalent and is suitable for maintenance and repair of existing systems, new product designs should specify RC1206FR-07422RL or CRCW1206422RFKEA to ensure long-term availability and manufacturer support.

Q: Are the automotive-qualified parts (CRCW1206422RFKEA and ERJ-8ENF4220V) required for non-automotive applications?

A: No. Automotive qualification (AEC-Q200) is not required for non-automotive applications. RC1206FR-07422RL, which lacks automotive qualification, is fully suitable for industrial, commercial, and consumer electronics. Automotive-qualified parts may be used in non-automotive applications without restriction, but the additional qualification adds cost without functional benefit in non-automotive contexts.

Q: What is Moisture Sensitivity Level 1, and why is it important?

A: Moisture Sensitivity Level (MSL) 1 indicates Unlimited shelf life without moisture control requirements. All four parts in this comparison carry MSL 1 rating, meaning they do not require special dry-pack storage, desiccant, or controlled humidity handling. This simplifies logistics and storage procedures.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, within the constraints of packaging format. If the PCB is designed for Tape & Reel components with standard pick-and-place equipment, RC3216F4220CS, RC1206FR-07422RL, and ERJ-8ENF4220V are interchangeable. If the assembly process uses Cut Tape or Digi-Reel equipment, CRCW1206422RFKEA is the appropriate choice. Verify assembly equipment compatibility before substitution.

Q: What compliance certifications apply to all substitute parts?

A: All four parts are ROHS3 Compliant and REACH Unaffected. These certifications confirm compliance with European Union Restriction of Hazardous Substances and Registration, Evaluation, Authorization and Restriction of Chemicals regulations. All parts carry ECCN EAR99 classification and HTSUS 8533.21.0030 tariff code.
