RC6432F22R6CS Equivalent & Substitute Parts

Part Overview

The RC6432F22R6CS is a 22.6 Ohm ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film resistor features moisture resistance and operates across a temperature range of -55°C to 155°C. The part is currently in active production status with 1041 pieces available in inventory. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when specific application certifications such as automotive AEC-Q200 qualification are mandated.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F22R6CS is determined by strict equivalence across the following critical parameters: resistance value (22.6 Ohms), tolerance (±1%), power rating (1W), package format (2512 / 6432 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts maintain these core electrical and mechanical specifications. Substitute parts may differ in packaging format (Tape & Reel versus bulk), specific dimensional tolerances within the 2512 package specification, and additional application certifications such as automotive AEC-Q200 qualification. The substitute parts listed are CRCW251222R6FKEG (Vishay Dale), ERJ-1TNF22R6U (Panasonic Electronic Components), and RMCF2512FT22R6 (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

The RC6432F22R6CS maintains active production status and is suitable for new designs. When substitution is required, CRCW251222R6FKEG (Vishay Dale) and RMCF2512FT22R6 (Stackpole Electronics Inc) are both active production alternatives with identical electrical specifications and ROHS3 compliance. Both substitute parts carry automotive AEC-Q200 certification, which provides additional qualification for automotive applications beyond the base Samsung part specification.

ERJ-1TNF22R6U (Panasonic Electronic Components) is electrically equivalent and ROHS3 compliant with AEC-Q200 certification; however, this part carries a "Not For New Designs" product status designation. This part remains available in inventory (4596 pieces) and is suitable for legacy system support and field replacement applications where the original part specification must be maintained.

All substitute parts are packaged in Tape & Reel format, whereas the main part packaging format is not specified. Dimensional variations exist within the 2512 package specification: the Samsung part measures 0.248" L x 0.126" W (6.30mm x 3.20mm), the Panasonic part measures 0.252" L x 0.126" W (6.40mm x 3.20mm), and both Vishay and Stackpole parts measure 0.248" L x 0.124" W to 0.126" W. Height seated maximum values range from 0.026" to 0.028" across all parts. These dimensional tolerances remain within the 2512 package specification and do not affect electrical performance or PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW251222R6FKEG directly replace RC6432F22R6CS in existing designs?

A: Yes. Both parts share identical electrical specifications: 22.6 Ohms ±1%, 1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are packaged in the 2512 (6432 Metric) format with 2 terminations. Dimensional variations fall within standard 2512 package tolerances and do not affect PCB layout or circuit performance.

Q: What is the difference between the Samsung RC6432F22R6CS and the Panasonic ERJ-1TNF22R6U?

A: Electrical specifications are identical. The primary difference is product status: the Samsung part is active for new designs, while the Panasonic part is designated "Not For New Designs." The Panasonic part is suitable for legacy system support and field replacement. Both parts are ROHS3 compliant with AEC-Q200 automotive certification.

Q: Why do the substitute parts have AEC-Q200 certification when the main part does not?

A: AEC-Q200 is an automotive qualification standard. The substitute parts from Vishay Dale, Panasonic, and Stackpole Electronics all carry this certification, which indicates they meet additional automotive reliability and testing requirements. This certification is not listed for the Samsung part but does not prevent its use in automotive applications. The presence of AEC-Q200 on substitute parts provides additional assurance for automotive system designs.

Q: Are there packaging format differences between the main part and substitutes?

A: The main part (RC6432F22R6CS) packaging format is not specified in the provided data. All three substitute parts are supplied in Tape & Reel (TR) format. If bulk or alternative packaging is required, this must be confirmed with the supplier or manufacturer.

Q: Do dimensional differences between substitute parts affect circuit performance?

A: No. All parts conform to the 2512 (6432 Metric) package specification. Dimensional variations (length 0.248" to 0.252", width 0.124" to 0.126", height 0.026" to 0.028") fall within standard package tolerances and do not affect electrical performance, thermal characteristics, or PCB layout compatibility.

Q: Which substitute part should be selected for new automotive designs?

A: For new automotive designs, CRCW251222R6FKEG (Vishay Dale) or RMCF2512FT22R6 (Stackpole Electronics Inc) are recommended. Both are in active production status and carry AEC-Q200 automotive certification. ERJ-1TNF22R6U is not recommended for new designs due to its "Not For New Designs" status, though it remains available for legacy system support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (CRCW251222R6FKEG, ERJ-1TNF22R6U, and RMCF2512FT22R6) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status, matching the compliance profile of the main part.
