Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F71R5CS are qualified based on the following electrical and mechanical parameters:

Electrical Parameters:

• Resistance value: 71.5 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

All identified substitute parts meet these core parameters. Additional qualifications such as AEC-Q200 automotive certification are noted where applicable but do not disqualify substitution for non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F71R5CS (Samsung Electro-Mechanics)

Primary selection for general-purpose applications. Active production status ensures long-term availability. Suitable for non-automotive applications requiring standard thick film resistor performance.

CRCW251271R5FKEG (Vishay Dale)

Recommended for automotive applications requiring AEC-Q200 qualification. Active production status supports sustained supply chain requirements. Identical electrical and thermal specifications with automotive-grade reliability certification.

ERJ-1TNF71R5U (Panasonic Electronic Components)

Designated as "Not For New Designs" status. Existing inventory availability (7152 Pcs) supports legacy system maintenance and repair applications. AEC-Q200 certification qualifies this part for automotive use in established designs. New design implementations should prioritize active production alternatives.

Frequently Asked Questions (FAQ)

Q: Can CRCW251271R5FKEG replace RC6432F71R5CS in all applications?

A: Yes. Both parts share identical electrical parameters (71.5 Ohms ±1%, 1W, ±100ppm/°C), thermal operating range (-55°C to 155°C), package type (2512), and compliance certifications (ROHS3, MSL 1). The CRCW251271R5FKEG includes additional AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications.

Q: What is the difference between the Samsung and Vishay parts?

A: The RC6432F71R5CS features moisture resistance as a specified characteristic. The CRCW251271R5FKEG is qualified to AEC-Q200 automotive standards. Both meet identical electrical, thermal, and dimensional specifications for the 2512 package. Physical dimensions show minor variation: Samsung 0.248" L x 0.126" W versus Vishay 0.248" L x 0.124" W, both within 2512 package tolerance.

Q: Why is ERJ-1TNF71R5U marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While electrically and mechanically equivalent, Panasonic has directed new design implementations toward alternative products. This part remains suitable for legacy system support and repair applications where existing designs are established.

Q: Are there dimensional compatibility concerns between these parts?

A: All three parts conform to the 2512 (6432 Metric) package standard. Dimensional variations fall within package tolerance: length ranges from 0.248" to 0.252", width from 0.124" to 0.126", and height from 0.026" to 0.028". These variations are standard for the 2512 package and do not affect PCB footprint compatibility.

Q: Which part should be selected for automotive applications?

A: Both CRCW251271R5FKEG and ERJ-1TNF71R5U carry AEC-Q200 certification. CRCW251271R5FKEG is the preferred choice due to active production status. ERJ-1TNF71R5U remains available for existing automotive designs but is not recommended for new automotive implementations.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
