Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TJ433U are qualified based on the following electrical and mechanical parameters:

• Resistance value: 43 kOhms
• Tolerance: ±5%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitutes meet these core parameters. Variations in product status and specific feature sets (such as anti-sulfur protection) are noted in the comparison table below.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1TJ433U is the primary selection due to its active product status and anti-sulfur protection feature, which provides enhanced reliability in harsh environments.

The CRCW251243K0JNEG from Vishay Dale is a direct functional equivalent with active product status. This part is suitable for applications where multi-source qualification is required or where Vishay Dale components are preferred in the supply chain.

The ERJ-1TYJ433U from Panasonic is electrically and mechanically equivalent but carries a "Not For New Designs" status. This part is appropriate only for legacy system maintenance, repair, or replacement applications where the original part number must be maintained.

All three parts satisfy automotive AEC-Q200 requirements and RoHS3 compliance. Physical dimensions are within acceptable tolerance for PCB footprint compatibility in the 2512 package family.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TYJ433U be used as a direct replacement for ERJ-S1TJ433U in new designs?

A: No. While electrically and mechanically equivalent, ERJ-1TYJ433U carries a "Not For New Designs" status. New designs should use ERJ-S1TJ433U or CRCW251243K0JNEG.

Q: Are there dimensional differences between the substitute parts?

A: The CRCW251243K0JNEG has slightly smaller dimensions (0.248" L x 0.124" W vs. 0.252" L x 0.126" W) but remains within the 2512 package specification. Both parts have identical 0.028" maximum seated height and are compatible with standard 2512 PCB footprints.

Q: Does the anti-sulfur feature of ERJ-S1TJ433U affect substitution decisions?

A: The anti-sulfur protection is a feature of the ERJ-S1TJ433U. If this specific protection is required for the application, only the ERJ-S1TJ433U should be used. For applications without this requirement, CRCW251243K0JNEG provides equivalent electrical performance.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed parts carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the difference in product status between these parts?

A: ERJ-S1TJ433U and CRCW251243K0JNEG are in active production. ERJ-1TYJ433U is not recommended for new designs but remains available for legacy applications. Active status parts are preferred for new product development.
