Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1433CS is determined by the following criteria:

Electrical Parameters (Critical):

• Resistance value: 143 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

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

Compliance Parameters:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

The ERJ-1TNF1433U from Panasonic Electronic Components meets all critical electrical and mechanical parameters. This part maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The 2512 package compatibility is confirmed. Compliance certifications (RoHS3, MSL 1, REACH Unaffected) are equivalent. The primary distinction is product status classification and automotive qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

RC6432F1433CS (Primary Selection): The RC6432F1433CS maintains Active product status, indicating ongoing manufacturer support and availability. This component is suitable for new designs and applications where long-term supply continuity is required. The part is currently in stock with 973 pieces available.

ERJ-1TNF1433U (Substitute Selection): The ERJ-1TNF1433U is electrically and mechanically equivalent to the RC6432F1433CS. However, this part carries "Not For New Designs" status, indicating that Panasonic has discontinued active development for this component. The ERJ-1TNF1433U includes AEC-Q200 automotive qualification, which may be beneficial for automotive applications but is not a requirement for general industrial use. This substitute is appropriate for legacy system maintenance, repair, or replacement scenarios where the original part is unavailable. Current inventory shows 4294 pieces in stock.

Dimensional Consideration: Minor dimensional variations exist between the two parts. The ERJ-1TNF1433U has a maximum length of 0.252" (6.40mm) compared to 0.248" (6.30mm) for the RC6432F1433CS, and a maximum seated height of 0.028" (0.70mm) versus 0.026" (0.66mm). These differences remain within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1433U replace RC6432F1433CS in new designs?

A: The ERJ-1TNF1433U is electrically and mechanically compatible with the RC6432F1433CS. However, the ERJ-1TNF1433U carries "Not For New Designs" status. For new designs, the RC6432F1433CS is the recommended selection due to its Active product status and ongoing manufacturer support.

Q: Are there dimensional compatibility issues between these parts?

A: Both parts use the 2512 (6432 Metric) package. The ERJ-1TNF1433U has slightly larger maximum dimensions (0.252" L vs 0.248" L, and 0.028" H vs 0.026" H). These variations fall within standard 2512 package tolerances and are compatible with standard 2512 PCB footprints.

Q: What is the significance of AEC-Q200 qualification on the ERJ-1TNF1433U?

A: AEC-Q200 is an automotive industry qualification standard. The ERJ-1TNF1433U meets this standard, making it suitable for automotive applications. The RC6432F1433CS does not specify this qualification. For non-automotive applications, this difference is not relevant to component selection.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RC6432F1433CS and ERJ-1TNF1433U are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures, providing maximum flexibility in supply chain management.

Q: Can these parts be used interchangeably in existing applications?

A: Yes. The RC6432F1433CS and ERJ-1TNF1433U are functionally equivalent for applications requiring 143 kOhms ±1% 1W thick film resistors in the 2512 package. Electrical performance, temperature characteristics, and compliance certifications are identical.
