ERJ-S1TJ2R2U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TJ2R2U is a 2.2 Ohms ±5% 1W chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. 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 with 1060 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility allows for functionally equivalent alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TJ2R2U is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Temperature coefficient: -100 / +600 ppm/°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-1TYJ2R2U meets all electrical and mechanical requirements for direct substitution. While this part carries a "Not For New Designs" status, it remains functionally equivalent and maintains identical performance characteristics, compliance certifications, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-1TYJ2R2U qualifies as a direct functional equivalent to the ERJ-S1TJ2R2U. Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications including AEC-Q200 automotive qualification and ROHS3 compliance.

The primary distinction is product lifecycle status: ERJ-S1TJ2R2U is in active production, while ERJ-1TYJ2R2U is designated "Not For New Designs." This designation does not affect electrical or mechanical compatibility. Selection between these parts should be based on supply availability, lead time requirements, and design phase considerations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TYJ2R2U be used as a direct replacement for ERJ-S1TJ2R2U in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance, tolerance, power rating, package dimensions, temperature range, and automotive certifications.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TYJ2R2U?

A: This designation indicates the part is in end-of-life phase. It remains fully functional and compliant but is not recommended for new product development. Existing designs using this part may continue without modification.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical footprint dimensions of 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm).

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-S1TJ2R2U and ERJ-1TYJ2R2U carry AEC-Q200 automotive qualification and are ROHS3 compliant.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
