RC3225F22R6CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F22R6CS is a 22.6 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format with 0.333W (1/3W) power rating. This component is classified as Active product status and is RoHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). The part is designed for applications requiring moisture-resistant thick film construction across an operating temperature range of -55°C to 155°C.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, temperature coefficient) and mechanical compatibility (package size, termination count) while accounting for variations in power rating and application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F22R6CS are qualified based on the following matching criteria:

Mandatory Matching Parameters:

• Resistance value: 22.6 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS3 compliance

Variable Parameters (Allowed Differences):

• Power rating: Substitutes may have equal or higher power ratings (0.5W acceptable for 0.333W applications)
• Application certifications: Automotive AEC-Q200 qualification is an additional feature, not a requirement for substitution
• Packaging format: Tape & Reel (TR) is compatible with bulk or alternative packaging
• Product status: Active or Not For New Designs both qualify as substitutes

The identified substitute parts maintain electrical and mechanical compatibility while offering alternative sourcing options from different manufacturers.

Parameter Comparison

Engineering Selection Recommendations

CRCW121022R6FKEA (Vishay Dale) is the primary substitute option. This part maintains Active product status, matching the RC3225F22R6CS in all critical electrical parameters. The 0.5W power rating provides increased thermal margin compared to the 0.333W original specification. Automotive AEC-Q200 certification qualifies this part for automotive and high-reliability applications. Dimensional compatibility is confirmed with maximum seated height of 0.60mm, which is lower than the original part's 0.66mm specification, ensuring PCB layout compatibility.

ERJ-14NF22R6U (Panasonic Electronic Components) is a secondary substitute option. This part is classified as Not For New Designs, indicating it is available for existing design support and replacement applications but not recommended for new product development. Electrical specifications and package dimensions are equivalent to CRCW121022R6FKEA. The maximum seated height of 0.70mm is slightly higher than the original specification but remains within typical PCB assembly tolerances. Automotive AEC-Q200 certification is present.

For new designs, CRCW121022R6FKEA is the recommended substitute. For legacy system support or replacement inventory, ERJ-14NF22R6U remains available.

Frequently Asked Questions (FAQ)

Q: Can CRCW121022R6FKEA replace RC3225F22R6CS in existing designs?

A: Yes. Both parts share identical resistance (22.6 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The 1210 package format and 2-termination configuration are mechanically compatible. The higher power rating (0.5W vs. 0.333W) provides additional thermal capability without affecting circuit performance.

Q: What is the difference between the Samsung and Vishay parts?

A: The primary differences are manufacturer, power rating, and application certification. RC3225F22R6CS is rated for 0.333W with moisture-resistant construction. CRCW121022R6FKEA is rated for 0.5W and includes Automotive AEC-Q200 certification. All electrical specifications and package dimensions are compatible.

Q: Is ERJ-14NF22R6U suitable for new product designs?

A: No. ERJ-14NF22R6U carries a "Not For New Designs" product status designation. This part is available for replacement and legacy system support only. For new designs, CRCW121022R6FKEA is the recommended substitute.

Q: Are there any PCB layout considerations when substituting these parts?

A: Dimensional variations are minimal. The seated height ranges from 0.60mm (CRCW121022R6FKEA) to 0.70mm (ERJ-14NF22R6U) compared to 0.66mm for the original RC3225F22R6CS. These variations fall within standard PCB assembly tolerances and do not require layout modifications. Length and width dimensions (3.20mm x 2.50-2.55mm) are equivalent across all three parts.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. RC3225F22R6CS, CRCW121022R6FKEA, and ERJ-14NF22R6U are all RoHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). REACH status is unaffected for all three parts.

Q: What is the significance of Automotive AEC-Q200 certification on the substitute parts?

A: Automotive AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards. This certification is present on CRCW121022R6FKEA and ERJ-14NF22R6U but not specified for RC3225F22R6CS. The certification is an additional qualification feature and does not affect electrical or mechanical substitution compatibility.
