RC6432F3323CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F3323CS is a 332 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with 853 units available in inventory.

Substitute parts are necessary when the primary part experiences supply constraints, when design requirements mandate specific manufacturer certifications (such as AEC-Q200 automotive qualification), or when alternative packaging formats are required for manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3323CS is determined by strict alignment with the following parameters:

Critical Matching Parameters:

• Resistance value: 332 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (equal or greater acceptable)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Supporting Parameters:

• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (equal or wider range acceptable)
• RoHS compliance: ROHS3 (exact match required)
• Moisture sensitivity: MSL 1 (equal or lower MSL acceptable)

All three identified substitute parts meet these criteria. Differences in physical dimensions (length, width, height) and packaging format (Tape & Reel versus bulk) do not affect electrical substitution eligibility but may impact manufacturing processes.

Parameter Comparison

Engineering Selection Recommendations

CRCW2512332KFKEG (Vishay Dale) is suitable for direct substitution. This part maintains active production status and carries AEC-Q200 automotive qualification. The Tape & Reel packaging format supports automated assembly processes. Physical dimensions (0.248" L x 0.124" W, height 0.028") are within acceptable tolerances for 2512 package specifications.

RMCF2512FT332K (Stackpole Electronics Inc) is suitable for direct substitution. This part maintains active production status and carries AEC-Q200 automotive qualification. Physical dimensions (0.248" L x 0.126" W, height 0.028") align with standard 2512 package specifications. Inventory availability is highest among substitute options at 7019 units.

ERJ-1TNF3323U (Panasonic Electronic Components) meets all electrical and mechanical substitution criteria but carries a "Not For New Designs" product status designation. This part is suitable only for replacement or maintenance applications where the original part number is no longer available. AEC-Q200 automotive qualification is present. Physical dimensions (0.252" L x 0.126" W, height 0.028") remain within acceptable 2512 package tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512332KFKEG replace RC6432F3323CS in all applications?

A: Yes. Both parts share identical electrical specifications (332 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and package designation (2512/6432 Metric). The primary difference is packaging format (Tape & Reel versus unspecified) and the addition of AEC-Q200 automotive qualification on the Vishay part. Physical dimensions are within acceptable tolerances for the 2512 package.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TNF3323U?

A: This designation indicates that Panasonic has discontinued this part for new product development. The part remains available for existing inventory and replacement purposes but should not be selected for new circuit designs. Use CRCW2512332KFKEG or RMCF2512FT332K for new designs.

Q: Are there differences in physical dimensions that affect PCB layout?

A: All four parts conform to the 2512 (6432 Metric) package specification. Minor dimensional variations exist: RC6432F3323CS and RMCF2512FT332K measure 0.248" L x 0.126" W; CRCW2512332KFKEG measures 0.248" L x 0.124" W; ERJ-1TNF3323U measures 0.252" L x 0.126" W. These variations fall within standard 2512 package tolerances and do not require PCB footprint redesign.

Q: What is the difference between Tape & Reel and other packaging formats?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly equipment. The RC6432F3323CS packaging format is not specified in the provided data. If your manufacturing process requires Tape & Reel format, CRCW2512332KFKEG, ERJ-1TNF3323U, and RMCF2512FT332K are all available in this format.

Q: Does AEC-Q200 qualification matter for non-automotive applications?

A: AEC-Q200 is an automotive industry qualification standard. For non-automotive applications, this certification is not required. However, AEC-Q200 qualified parts undergo additional reliability testing and are acceptable for general-purpose use. The RC6432F3323CS does not specify AEC-Q200 qualification but remains suitable for non-automotive applications.

Q: Can I use a substitute part with higher power rating?

A: Yes. A 1W resistor can be replaced with a higher power-rated part in the same package if available. However, all identified substitutes are rated at 1W, matching the original specification. Higher power ratings would require a larger package size and are not applicable here.

Q: What is MSL 1 (Unlimited) and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates the lowest moisture sensitivity classification. Parts with MSL 1 have unlimited shelf life and do not require special moisture-controlled storage or baking procedures before soldering. All four parts in this comparison carry MSL 1 rating.
