RC6432F2102CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2102CS is a 21 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 maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

The part is currently in Active product status with 702 units available in inventory. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to supply constraints, design flexibility, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2102CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 21 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture sensitivity: MSL 1 or better

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

The identified substitute part ERJ-1TNF2102U from Panasonic Electronic Components meets all electrical and mechanical equivalence criteria. This part maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The 2512 package format ensures mechanical compatibility with existing PCB layouts and assembly processes. Minor dimensional variations (length 6.40mm vs 6.30mm, height 0.70mm vs 0.66mm) remain within standard PCB design tolerances for this package class.

Engineering Selection Recommendations

RC6432F2102CS Selection Criteria: The Samsung RC6432F2102CS is appropriate for applications requiring an active product status with standard commercial-grade thick film resistor performance. With 702 units in current inventory, this part supports immediate procurement for standard industrial and consumer applications requiring 21 kOhms ±1% 1W specifications.

ERJ-1TNF2102U Selection Criteria: The Panasonic ERJ-1TNF2102U provides electrical and mechanical equivalence with the addition of AEC-Q200 automotive qualification. However, this part carries a "Not For New Designs" product status designation. Selection of this substitute is limited to legacy design support, existing production continuity, or applications where automotive-grade qualification is specifically required and the product status restriction is acceptable to the design authority.

Substitution Decision Logic:

• For new designs requiring standard specifications: Use RC6432F2102CS
• For automotive applications with AEC-Q200 requirement: Use ERJ-1TNF2102U only if product status restriction is approved
• For legacy design support: ERJ-1TNF2102U provides full electrical and mechanical compatibility

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2102U be used as a direct replacement for RC6432F2102CS in existing designs?

A: Yes, from an electrical and mechanical standpoint. The ERJ-1TNF2102U maintains identical resistance (21 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both components use the 2512 (6432 Metric) package with two terminations. Minor dimensional differences (length 6.40mm vs 6.30mm, height 0.70mm vs 0.66mm) remain within standard PCB design tolerances for this package class. However, the ERJ-1TNF2102U carries a "Not For New Designs" status, which may require design authority approval for substitution in active production.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF2102U?

A: This designation indicates that Panasonic has classified this part as suitable for legacy support and existing production continuity only. New designs should not incorporate this part. If substitution is necessary due to supply constraints or other factors, formal design change documentation and approval from the responsible engineering authority is required.

Q: Does the AEC-Q200 qualification on ERJ-1TNF2102U provide additional benefits?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. If your application requires automotive-grade components, the ERJ-1TNF2102U meets this requirement. The RC6432F2102CS does not carry this specification. Conversely, if automotive qualification is not required, this additional feature does not provide functional benefit for the specified 21 kOhms ±1% 1W electrical performance.

Q: Are there any packaging differences between these parts?

A: Both parts use the 2512 (6432 Metric) package format. The RC6432F2102CS is supplied in standard packaging, while the ERJ-1TNF2102U is supplied in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel format is standard for automated assembly operations.

Q: What compliance certifications apply to both parts?

A: Both RC6432F2102CS and ERJ-1TNF2102U are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8533.21.0030. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions during storage or handling.
