RC6432F6652CS Equivalent & Substitute Parts

Part Overview

The RC6432F6652CS is a 66.5 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 ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 865 units available in inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for functionally equivalent alternatives that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F6652CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 66.5 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package format: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The ERJ-1TNF6652U 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 package dimensions are within acceptable manufacturing tolerances for the 2512 format, and compliance certifications are equivalent.

Parameter Comparison

Engineering Selection Recommendations

RC6432F6652CS (Samsung Electro-Mechanics): This part is the primary selection for new designs. Active production status ensures long-term availability and supply chain stability. Current inventory of 865 units supports immediate procurement requirements. The moisture-resistant thick film construction and ROHS3 compliance meet standard industrial and commercial application requirements.

ERJ-1TNF6652U (Panasonic Electronic Components): This part is designated as "Not For New Designs" by the manufacturer. However, it remains functionally equivalent across all critical electrical and mechanical parameters. The part carries AEC-Q200 automotive qualification, which exceeds standard industrial requirements. This substitute is suitable for replacement applications, legacy system maintenance, or situations where the primary part is unavailable. Higher inventory availability (4954 units) may support expedited procurement in supply-constrained scenarios. Dimensional variations (0.252" vs 0.248" length; 0.028" vs 0.026" height) are within standard PCB layout tolerances for 2512 package components.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6652U be used as a direct replacement for RC6432F6652CS?

A: Yes. Both parts share identical electrical specifications (66.5 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 2512 (6432 Metric) format. Dimensional differences are within standard manufacturing tolerances for this package class. Both parts are ROHS3 compliant with MSL 1 ratings.

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

A: This designation indicates that Panasonic is not recommending the ERJ-1TNF6652U for new product development. However, the part remains available and functionally equivalent. This status does not affect substitution suitability for replacement, maintenance, or non-critical applications where the primary part is unavailable.

Q: Are there dimensional compatibility concerns between these parts?

A: Dimensional variations exist within acceptable tolerances. The Panasonic part is 0.004" longer (6.40mm vs 6.30mm) and 0.002" taller (0.70mm vs 0.66mm). These differences are negligible for standard PCB layouts designed for 2512 package components and do not affect electrical performance or thermal characteristics.

Q: Do both parts meet automotive qualification standards?

A: The Panasonic ERJ-1TNF6652U carries AEC-Q200 automotive qualification. The Samsung RC6432F6652CS does not list automotive certification. For automotive applications, the Panasonic part provides additional qualification assurance, though both parts meet equivalent industrial compliance standards.

Q: What is the difference in packaging between these parts?

A: The Samsung RC6432F6652CS is supplied in standard packaging format. The Panasonic ERJ-1TNF6652U is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly operations. Both packaging formats are compatible with standard SMD placement equipment.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.21.0030). No regulatory or compliance barriers exist for substitution between these parts.
