Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TJ240U is determined by strict equivalence across the following critical parameters:

• Resistance value: 24 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the ERJ-S1TJ240U in applications requiring 24 Ohm 1W thick film resistors with automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1TJ240U (Panasonic, Active status) is the primary selection. This part maintains active production status and includes anti-sulfur coating, providing enhanced reliability in harsh automotive environments.

The CRCW251224R0JNEG (Vishay Dale) and RMCF2512JT24R0 (Stackpole) are direct substitutes with active product status and equivalent electrical and mechanical specifications. Both are suitable for new designs and provide supply chain alternatives.

The ERJ-1TYJ240U (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance, repair, or replacement applications where the original part number must be maintained for compatibility.

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and identical operating temperature ranges, ensuring seamless integration into existing designs without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TYJ240U be used as a direct replacement for ERJ-S1TJ240U in new designs?

A: No. While ERJ-1TYJ240U is electrically and mechanically equivalent, it carries "Not For New Designs" status. For new designs, use ERJ-S1TJ240U, CRCW251224R0JNEG, or RMCF2512JT24R0.

Q: Are all substitute parts automotive-qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and operate across the identical temperature range of -55°C to 155°C.

Q: What is the difference between ERJ-S1TJ240U and ERJ-1TYJ240U?

A: Both parts are 24 Ohm ±5% 1W thick film resistors in 2512 package with identical electrical specifications. The primary difference is product status: ERJ-S1TJ240U is Active and includes anti-sulfur coating, while ERJ-1TYJ240U is Not For New Designs.

Q: Can I mix different manufacturers in the same circuit board?

A: Yes. All substitute parts meet identical electrical and mechanical specifications, RoHS compliance, and AEC-Q200 qualification. They are functionally interchangeable and can be used together in the same application.

Q: Are there dimensional differences between substitute parts?

A: Dimensional variations are minimal. ERJ-S1TJ240U and RMCF2512JT24R0 measure 0.252" L × 0.126" W, while CRCW251224R0JNEG measures 0.248" L × 0.124" W. All parts fit the 2512 (6432 Metric) package footprint with maximum seated height of 0.028" (0.70mm).

Q: What is the moisture sensitivity level for these parts?

A: All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
