RC6432F2432CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2432CS is a 24.3 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 1032 units available in inventory.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements mandate specific certifications such as automotive qualification, or when alternative sourcing strategies are implemented to optimize procurement costs and lead times.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2432CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24.3 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The ERJ-1TNF2432U from Panasonic Electronic Components meets all mandatory parameters and qualifies as a direct substitute. This part maintains identical electrical specifications and environmental ratings while offering additional automotive AEC-Q200 qualification. The dimensional variance (0.252" L x 0.126" W versus 0.248" L x 0.126" W) and height difference (0.028" maximum versus 0.026" maximum) remain within acceptable mechanical tolerances for standard PCB footprint compatibility in the 2512 package class.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2432CS (Samsung Electro-Mechanics): Select this part for new designs requiring active production status and standard industrial applications. The component is currently in active product status with established supply availability (1032 units in stock). This part is suitable for general-purpose applications where automotive qualification is not required.

ERJ-1TNF2432U (Panasonic Electronic Components): This substitute is qualified for automotive applications under AEC-Q200 standard and carries ROHS3 compliance identical to the primary part. However, this part is designated "Not For New Designs," indicating it is in mature or end-of-life status. Selection of this substitute should be limited to legacy design support, replacement inventory, or applications where automotive qualification is a mandatory requirement and the design is already established. The higher inventory availability (4342 units) may provide short-term sourcing advantages despite the product status designation.

Both parts satisfy identical electrical and environmental specifications. Selection between them depends on application requirements regarding automotive qualification and design phase considerations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2432U be used as a direct replacement for RC6432F2432CS in existing designs?

A: Yes. Both parts share identical electrical specifications (24.3 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and are ROHS3 compliant with MSL 1 rating. The dimensional differences (0.004" length variance, 0.002" height variance) are within standard PCB footprint tolerances for 2512 package components. Mechanical compatibility is confirmed for standard surface mount assembly processes.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF2432U?

A: This designation indicates the part is in mature or end-of-life phase within Panasonic's product portfolio. While the component remains functionally equivalent and available, the manufacturer does not recommend its use in new product development. This part is appropriate for legacy design support, replacement stock, or applications where design is already finalized and automotive AEC-Q200 qualification is required.

Q: Are there dimensional compatibility concerns between these two parts?

A: Dimensional differences are minimal and within acceptable tolerances. The RC6432F2432CS measures 0.248" L x 0.126" W x 0.026" H (max), while the ERJ-1TNF2432U measures 0.252" L x 0.126" W x 0.028" H (max). These variations fall within standard PCB design margins for 2512 package footprints and do not require layout modifications for standard applications.

Q: Which part should be selected for automotive applications?

A: The ERJ-1TNF2432U carries AEC-Q200 automotive qualification, making it the specified choice for automotive applications. The RC6432F2432CS does not list automotive qualification in its specifications. If automotive qualification is a design requirement, ERJ-1TNF2432U is the appropriate selection despite its "Not For New Designs" status.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Both carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture protection requirements during storage or handling.
