RC6432F88R7CS Equivalent & Substitute Parts

Part Overview

The RC6432F88R7CS is an 88.7 Ohm ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant. The part is currently in active production status with 718 units available in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package class and performance parameters. The ERJ-1TNF88R7U from Panasonic Electronic Components provides functional equivalence while offering automotive-grade qualification through AEC-Q200 certification, though it carries a "Not For New Designs" status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F88R7CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 88.7 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Specifications:

• Package classification: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

The ERJ-1TNF88R7U meets all electrical and mechanical equivalence criteria. Physical dimensions show minor variations (length 6.40mm vs. 6.30mm; height 0.70mm vs. 0.66mm) within acceptable tolerances for the 2512 package class. The substitute part adds AEC-Q200 automotive qualification as an additional feature.

Engineering Selection Recommendations

Primary Selection: RC6432F88R7CS

The RC6432F88R7CS is the recommended choice for new designs. This part maintains active production status with established supply availability (718 units in stock). It meets all ROHS3 and REACH compliance requirements for current applications.

Alternative Selection: ERJ-1TNF88R7U

The ERJ-1TNF88R7U provides functional equivalence with identical electrical and mechanical specifications. This Panasonic part is suitable for applications requiring AEC-Q200 automotive qualification. However, its "Not For New Designs" status indicates that Panasonic has discontinued active development for this model. Selection of this substitute should be limited to legacy system support, field replacements, or applications where automotive-grade certification is a specific requirement and the design is already established.

Packaging Consideration:

The ERJ-1TNF88R7U is supplied in Tape & Reel (TR) format, which may differ from the RC6432F88R7CS packaging specification. Verify packaging compatibility with assembly equipment and procurement workflows before substitution.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF88R7U be used as a direct replacement for RC6432F88R7CS in new designs?

A: Electrical and mechanical specifications are equivalent. However, the ERJ-1TNF88R7U carries "Not For New Designs" status from the manufacturer. New designs should specify the RC6432F88R7CS to ensure long-term supply continuity and manufacturer support.

Q: What are the physical dimension differences between these parts?

A: Length differs by 0.10mm (6.40mm vs. 6.30mm) and height by 0.04mm (0.70mm vs. 0.66mm). Both dimensions fall within acceptable tolerances for the 2512 package class and do not affect PCB layout or assembly compatibility.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both parts operate across -55°C to 155°C with identical ±100ppm/°C temperature coefficients. Temperature performance is equivalent.

Q: What is the significance of AEC-Q200 certification on the ERJ-1TNF88R7U?

A: AEC-Q200 is an automotive industry qualification standard. This certification is present on the Panasonic part but not specified for the Samsung part. If automotive-grade qualification is required by application specifications, the ERJ-1TNF88R7U provides this additional assurance. If not required, this difference is not relevant to substitution decisions.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel vs. other formats) does not affect electrical or mechanical compatibility. However, it impacts procurement, storage, and assembly processes. Verify that assembly equipment and supply chain workflows support the available packaging format before substitution.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC6432F88R7CS and ERJ-1TNF88R7U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
