RC6432F6653CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F6653CS is a 665 kOhms ±1% 1W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This component is classified as Active product status and is designed for general-purpose applications requiring moisture-resistant thick film construction. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the main part's functional requirements. The primary substitute identified is the ERJ-1TNF6653U from Panasonic Electronic Components, which shares identical resistance, tolerance, power rating, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Electrical Parameters (Must Match):

• Resistance value: 665 kOhms
• Tolerance: ±1%
• Power rating: 1W (minimum)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 or better
• REACH Status: REACH Unaffected

The ERJ-1TNF6653U from Panasonic satisfies all substitution criteria. Physical dimensions show minor variations (length 6.40mm vs. 6.30mm; height 0.70mm vs. 0.66mm) within acceptable PCB assembly tolerances for 2512 package specifications. The Panasonic part includes AEC-Q200 automotive qualification, which represents an additional compliance certification not present in the main part.

Engineering Selection Recommendations

Primary Selection: RC6432F6653CS (Samsung Electro-Mechanics)

The RC6432F6653CS is the recommended choice for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It meets all ROHS3 and REACH compliance requirements with unlimited moisture sensitivity level, suitable for standard industrial and commercial applications.

Substitute Selection: ERJ-1TNF6653U (Panasonic Electronic Components)

The ERJ-1TNF6653U is a qualified substitute when the primary part is unavailable. This part matches all critical electrical and mechanical parameters. However, it carries "Not For New Designs" product status, indicating Panasonic has discontinued active development for this specific model number. The ERJ-1TNF6653U includes AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability standards.

Selection Criteria:

• Use RC6432F6653CS for new product designs and long-term production runs
• Use ERJ-1TNF6653U only when RC6432F6653CS is unavailable and existing inventory is acceptable
• Both parts are ROHS3 compliant and suitable for the same operating temperature range (-55°C ~ 155°C)
• Physical dimension variations (length and height) are within standard PCB assembly tolerances for 2512 package specifications

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6653U be used as a direct replacement for RC6432F6653CS in existing designs?

A: Yes. The ERJ-1TNF6653U meets all electrical specifications (665 kOhms ±1%, 1W, ±100ppm/°C) and mechanical requirements (2512 package, thick film composition). Physical dimensions vary slightly (length 6.40mm vs. 6.30mm; height 0.70mm vs. 0.66mm) but remain within standard PCB assembly tolerances for this package class. Both parts are ROHS3 compliant with MSL 1 rating.

Q: Why is the Panasonic part marked "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic has discontinued active development and marketing of the ERJ-1TNF6653U model. This status does not affect functional performance or compliance certifications. The part remains available from existing inventory but should not be selected for new product development. The RC6432F6653CS (Active status) is the preferred choice for new designs.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical power rating (1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Thermal performance and electrical stability are equivalent.

Q: What is the significance of AEC-Q200 qualification on the Panasonic part?

A: AEC-Q200 is an automotive industry standard qualification for passive components. The ERJ-1TNF6653U carries this certification, while the RC6432F6653CS does not specify automotive qualification. For applications requiring automotive-grade reliability, the Panasonic part provides documented compliance. For non-automotive applications, this certification is not a requirement.

Q: Are packaging formats different between these parts?

A: The RC6432F6653CS is supplied in standard packaging format. The ERJ-1TNF6653U is supplied in Tape & Reel (TR) format. Both use the same 2512 (6432 Metric) component package. Tape & Reel format is standard for automated PCB assembly processes.

Q: Can I mix these parts in the same production batch?

A: Both parts are electrically and mechanically equivalent and can be used interchangeably in the same circuit design. However, mixing different manufacturers in a single production batch may require separate traceability documentation and quality control records. Consult your procurement and quality assurance procedures.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts carry MSL 1 (Unlimited), the lowest moisture sensitivity classification. This means the components can be stored indefinitely without special moisture control measures and do not require baking before soldering. Standard warehouse storage conditions are acceptable.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC6432F6653CS and ERJ-1TNF6653U are ROHS3 compliant and REACH unaffected, meeting current European Union and international environmental regulations for electronic components.
