Key Parameters

Substitute Part Grouping Explanation

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

Critical Matching Parameters:

• Resistance value: 68.1 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical criteria. Variations in physical dimensions (length, width, height) within manufacturing tolerances and differences in packaging format (Tape & Reel vs. bulk) do not affect functional substitutability. Product status and application-specific certifications (such as AEC-Q200 for automotive use) are noted for selection context but do not restrict substitution at the component level.

Parameter Comparison

Engineering Selection Recommendations

RC6432F68R1CS (Samsung Electro-Mechanics) - Primary Reference

Active product status with moisture resistant features. Suitable for general industrial applications requiring standard thick film resistor performance. ROHS3 compliant and REACH unaffected.

Use only for legacy system maintenance or replacement applications where original part sourcing is critical.

Frequently Asked Questions (FAQ)

Q: Can CRCW251268R1FKEG directly replace RC6432F68R1CS in existing designs?

A: Yes. Both parts share identical electrical specifications (68.1 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and package designation (2512/6432 Metric). Physical dimensions are within manufacturing tolerances. Direct substitution is functionally equivalent.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Tape & Reel (TR) packaging is used for automated assembly processes and provides components on continuous carrier tape. Bulk packaging is used for manual assembly or smaller volume applications. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Why is ERJ-1TNF68R1U marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. The part remains functionally equivalent and is suitable for replacement or maintenance of existing systems. For new designs, CRCW251268R1FKEG or RMCF2512FT68R1 are recommended.

Q: Are all substitute parts AEC-Q200 certified?

A: CRCW251268R1FKEG and RMCF2512FT68R1 carry AEC-Q200 automotive certification. RC6432F68R1CS does not list this certification. AEC-Q200 certification indicates automotive-grade reliability testing. Selection depends on application requirements.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture exposure precautions. All listed parts have MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts operate across -55°C to 155°C with identical ±100ppm/°C temperature coefficient. Thermal performance is equivalent across the specified operating range.
