ERJ-S1TJ434U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TJ434U is a 430 kOhms ±5% 1W chip resistor manufactured by Panasonic Electronic Components in the 2512 (6432 Metric) package. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status. Substitute parts may be required due to supply constraints, inventory availability, or design phase transitions where legacy series components are no longer recommended for new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TJ434U is determined by strict equivalence across the following parameters:

• Resistance value: 430 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

The ERJ-1TYJ434U qualifies as a direct substitute based on identical electrical specifications and package dimensions. This part belongs to the ERJ-1T series and carries a "Not For New Designs" status, indicating it remains functionally equivalent but is transitioning out of active recommendation for new product development.

Parameter Comparison

Engineering Selection Recommendations

For new product designs, the ERJ-S1TJ434U is the preferred selection due to its active production status and ongoing manufacturer support. The ERJ-1TYJ434U remains electrically and mechanically equivalent and is suitable for replacement applications, legacy system maintenance, or situations where existing inventory must be utilized. Both parts meet identical automotive and compliance requirements, including AEC-Q200 qualification and ROHS3 compliance. Selection between these parts should be based on supply availability, design phase requirements, and inventory management objectives rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TYJ434U be used as a direct replacement for ERJ-S1TJ434U in automotive applications?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. Both carry AEC-Q200 automotive qualification. The primary difference is product status; ERJ-1TYJ434U is marked "Not For New Designs" but remains functionally equivalent for replacement and maintenance applications.

Q: Are there any differences in the 2512 package dimensions between these parts?

A: No. Both parts use the identical 2512 (6432 Metric) package with dimensions of 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm). PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TYJ434U?

A: This designation indicates the part is in a transition phase and the manufacturer recommends using ERJ-S1TJ434U for new product development. However, ERJ-1TYJ434U remains available and fully functional for existing designs, maintenance, and replacement scenarios.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both ERJ-S1TJ434U and ERJ-1TYJ434U are ROHS3 compliant, REACH unaffected, carry MSL 1 (unlimited moisture sensitivity), and hold AEC-Q200 automotive qualification. Compliance profiles are identical.

Q: What is the temperature coefficient significance for these resistors?

A: The ±200ppm/°C temperature coefficient indicates the resistance value will change by a maximum of 200 parts per million for each degree Celsius change in operating temperature. This specification is identical between both parts and is typical for thick film chip resistors in automotive applications.
