RC6432F2552CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2552CS is a 25.5 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 currently in active production status. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. The primary substitute listed is the ERJ-1TNF2552U from Panasonic Electronic Components, which shares identical electrical characteristics while offering automotive-grade AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2552CS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 25.5 kOhms (exact match required)
• Tolerance: ±1% (minimum requirement)
• Power rating: 1W (minimum requirement)
• Package: 2512 (6432 Metric) footprint
• Composition: Thick film technology
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The ERJ-1TNF2552U from Panasonic meets all primary substitution criteria. Both parts share identical electrical specifications, temperature characteristics, and package dimensions within acceptable manufacturing tolerances. The Panasonic part carries additional AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2552CS (Samsung Electro-Mechanics): Select this part for new designs requiring active production status and standard industrial-grade thick film resistor performance. The component is currently in active production with 818 units in stock. Use this part when automotive qualification is not a design requirement.

ERJ-1TNF2552U (Panasonic Electronic Components): This part is marked "Not For New Designs" and should be used only for replacement, repair, or legacy system maintenance where the original Samsung part is unavailable. The Panasonic substitute carries AEC-Q200 automotive qualification, which provides additional reliability data for applications requiring automotive-grade components. The part is available in higher inventory (2886 units). Physical dimensions show minor variations within acceptable manufacturing tolerances: length difference of 0.004" (0.10mm) and height difference of 0.002" (0.04mm).

Substitution Decision Logic:

• For new designs: Use RC6432F2552CS
• For replacement or legacy applications: ERJ-1TNF2552U is electrically and mechanically compatible
• Both parts meet ROHS3 compliance and MSL 1 requirements
• Dimensional variations are within standard PCB assembly tolerances

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2552U replace RC6432F2552CS in existing designs?

A: Yes. The ERJ-1TNF2552U is electrically equivalent with identical resistance value (25.5 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimensions are compatible within standard manufacturing tolerances for the 2512 package footprint.

Q: What is the significance of the "Not For New Designs" status on the Panasonic part?

A: This designation indicates that Panasonic has discontinued or is phasing out the ERJ-1TNF2552U from their active product line. The part remains available for replacement and repair applications but should not be selected for new circuit designs. The Samsung RC6432F2552CS maintains active production status and is the preferred choice for new designs.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within acceptable tolerances. The Panasonic part is 0.004" (0.10mm) longer and 0.002" (0.04mm) taller than the Samsung part. These differences fall within standard PCB assembly tolerances and do not affect footprint compatibility or circuit performance.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the RC6432F2552CS and ERJ-1TNF2552U carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Both parts can be stored and handled under standard conditions without special desiccant packaging requirements.

Q: What does AEC-Q200 qualification on the Panasonic part mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability for automotive applications. The Panasonic ERJ-1TNF2552U meets this standard, but this qualification does not restrict its use in non-automotive applications. The Samsung part does not carry this specific automotive certification.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the RC6432F2552CS and ERJ-1TNF2552U are ROHS3 compliant, meeting European Union restrictions on hazardous substances. Both parts are also REACH unaffected and classified as EAR99 for export control purposes.

Q: Can I use the Panasonic part in a new design if the Samsung part becomes unavailable?

A: No. The Panasonic ERJ-1TNF2552U is marked "Not For New Designs." For new designs, source the Samsung RC6432F2552CS or identify an alternative part from an active product line that meets the same electrical and mechanical specifications. The Panasonic part is reserved for replacement and repair of existing systems.
