ERJ-S1TJ910U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TJ910U is a 91 Ohm ±5% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently active in production with 856 pieces in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across multiple suppliers, or when specific inventory constraints necessitate alternative sourcing options while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TJ910U are qualified based on the following criteria:

• Resistance value: 91 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)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed meet these criteria and are electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1TJ910U (Panasonic), CRCW251291R0JNEG (Vishay Dale), or RMCF2512JT91R0 (Stackpole Electronics Inc). All three maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-1TYJ910U carries a "Not For New Designs" status and should be used only for legacy design updates or replacement applications where the original part number must be maintained.

All listed substitutes are electrically and mechanically identical and support direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TYJ910U be used as a substitute for ERJ-S1TJ910U in new designs?

A: No. ERJ-1TYJ910U carries a "Not For New Designs" product status. For new designs, use CRCW251291R0JNEG, RMCF2512JT91R0, or the primary part ERJ-S1TJ910U.

Q: Are all substitute parts mechanically compatible with the 2512 package footprint?

A: Yes. All listed parts use the 2512 (6432 Metric) package. Minor dimensional variations exist (length 0.248" to 0.252", width 0.124" to 0.126"), but these fall within standard PCB footprint tolerances and do not affect board-level compatibility.

Q: Do all substitute parts meet automotive AEC-Q200 requirements?

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

Q: What is the difference between ERJ-S1TJ910U and ERJ-1TYJ910U?

A: Both are 91 Ohm 1W 2512 resistors from Panasonic with identical electrical specifications. The primary difference is product status: ERJ-S1TJ910U is Active, while ERJ-1TYJ910U is Not For New Designs. ERJ-S1TJ910U includes anti-sulfur coating.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
