Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2430CS is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Resistance value: 243 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package / Case: 2512 (6432 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 (different suppliers)
• Product status (Active or Not For New Designs)
• Packaging format (Tape & Reel, Cut Tape, or standard packaging)
• Physical dimensions within tolerance (length ±0.004", width ±0.000", height ±0.002")
• Additional certifications (AEC-Q200 automotive qualification)

The two substitute parts identified—ERJ-1TNF2430U (Panasonic) and RMCF2512FT243R (Stackpole Electronics)—satisfy all mandatory parameters while offering enhanced automotive qualification through AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC6432F2430CS): Select the Samsung Electro-Mechanics RC6432F2430CS for applications requiring an Active product status with moisture-resistant thick film construction. This part is suitable for general industrial applications without automotive qualification requirements. Current inventory of 1099 pieces supports immediate availability.

Secondary Selection (RMCF2512FT243R): Select the Stackpole Electronics RMCF2512FT243R when AEC-Q200 automotive qualification is required or when extended supply chain resilience is necessary. This part maintains Active product status with the highest current inventory (21595 pieces). Physical dimensions match the primary part exactly. Cut Tape packaging format accommodates both manual and automated assembly processes.

Tertiary Selection (ERJ-1TNF2430U): Select the Panasonic Electronic Components ERJ-1TNF2430U only when Tape & Reel packaging is mandated by assembly equipment specifications. This part carries "Not For New Designs" status, indicating it is suitable for legacy system maintenance or replacement applications only. Physical dimensions show minor height variation (0.028" vs. 0.026") within acceptable tolerance for 2512 package specifications.

All three parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2430U replace RC6432F2430CS in new product designs?

A: No. The ERJ-1TNF2430U carries "Not For New Designs" product status. This designation indicates the part is available for existing applications and legacy system support only. For new designs, use RC6432F2430CS (Active) or RMCF2512FT243R (Active).

Q: What is the significance of the 0.002" height difference between substitute parts?

A: The height variation (0.026" to 0.028" seated maximum) falls within standard 2512 package tolerance specifications. This difference does not affect electrical performance or PCB assembly compatibility. Verify clearance in applications with height-constrained layouts.

Q: Are all substitute parts suitable for automotive applications?

A: Only RMCF2512FT243R and ERJ-1TNF2430U carry AEC-Q200 automotive certification. The primary part RC6432F2430CS does not include automotive qualification. Select AEC-Q200 certified parts for automotive or safety-critical applications.

Q: What packaging formats are available, and how do they affect assembly?

A: RC6432F2430CS uses standard packaging; RMCF2512FT243R uses Cut Tape (CT); ERJ-1TNF2430U uses Tape & Reel (TR). Cut Tape and Tape & Reel formats are compatible with automated pick-and-place assembly equipment. Standard packaging accommodates manual placement. Verify compatibility with your assembly process specifications.

Q: Do all parts meet moisture sensitivity requirements?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out requirement prior to soldering. This classification applies to all substitute options.

Q: What is the inventory status for each part?

A: RC6432F2430CS: 1099 pieces; ERJ-1TNF2430U: 4197 pieces; RMCF2512FT243R: 21595 pieces. RMCF2512FT243R offers the highest inventory availability for supply chain continuity.

Q: Are there compliance differences between the three parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. No compliance differentiation exists between the primary and substitute parts.
