Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4870CS is determined by strict alignment of the following parameters:

Electrical Parameters (Critical):

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

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

Compliance Parameters (Required):

• RoHS3 compliance
• MSL 1 rating
• REACH Unaffected status

Two substitute parts meet these criteria: CRCW2512487RFKEG (Vishay Dale) and ERJ-1TNF4870U (Panasonic Electronic Components). Both maintain identical electrical specifications and package dimensions while offering additional automotive AEC-Q200 qualification. The Panasonic part carries "Not For New Designs" status, indicating it remains available for existing applications but is not recommended for new circuit development.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Development: CRCW2512487RFKEG (Vishay Dale) is the primary substitute for new circuit designs. This part maintains Active product status, identical electrical and mechanical specifications, and adds AEC-Q200 automotive qualification. The marginal dimensional variance (width 3.15mm vs. 3.20mm, height 0.70mm vs. 0.66mm) remains within standard PCB layout tolerances for 2512 package footprints.

For Existing Production Continuity: ERJ-1TNF4870U (Panasonic Electronic Components) remains available for sustaining existing applications. Despite "Not For New Designs" classification, this part meets all electrical and compliance requirements. The dimensional profile (6.40mm x 3.20mm x 0.70mm) is compatible with standard 2512 footprints.

Compliance Alignment: All three parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory compatibility across industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512487RFKEG directly replace RC6432F4870CS in existing designs?

A: Yes. Both parts share identical resistance (487 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Dimensional differences (width 3.15mm vs. 3.20mm, height 0.70mm vs. 0.66mm) are within standard 2512 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of AEC-Q200 rating on substitute parts?

A: AEC-Q200 is an automotive qualification standard. Both CRCW2512487RFKEG and ERJ-1TNF4870U carry this certification, indicating enhanced reliability testing for automotive environments. The RC6432F4870CS does not specify this rating but remains suitable for general industrial applications.

Q: Why is ERJ-1TNF4870U marked "Not For New Designs"?

A: This designation indicates the part is in mature/legacy status. While electrically and mechanically equivalent, Panasonic recommends CRCW2512487RFKEG for new circuit development. ERJ-1TNF4870U remains available for sustaining existing production.

Q: Are there dimensional concerns when substituting these parts?

A: Dimensional variations are minimal. The RC6432F4870CS measures 6.30mm x 3.20mm x 0.66mm (max height). CRCW2512487RFKEG measures 6.30mm x 3.15mm x 0.70mm, and ERJ-1TNF4870U measures 6.40mm x 3.20mm x 0.70mm. All fall within standard 2512 (6432 Metric) package specifications and are compatible with standard PCB footprints.

Q: Do all three parts share identical compliance certifications?

A: Yes. RC6432F4870CS, CRCW2512487RFKEG, and ERJ-1TNF4870U are all ROHS3 compliant, MSL 1 rated, and REACH Unaffected. They are interchangeable from a regulatory compliance perspective.

Q: What packaging formats are available for these substitutes?

A: CRCW2512487RFKEG and ERJ-1TNF4870U are supplied in Tape & Reel (TR) format. The RC6432F4870CS packaging format is not specified in the provided data.
