ERJ-S1TF2260U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF2260U is a 226 Ohms ±1% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This component 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 1027 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across multiple suppliers, or when inventory optimization is needed while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2260U is determined by strict equivalence across the following parameters:

• Resistance value: 226 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these criteria. Dimensional variations within supplier tolerances (length, width, height) do not affect functional substitution in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1TF2260U (Panasonic), AC2512FK-07226RL (YAGEO), or CRCW2512226RFKEG (Vishay Dale). All three are actively manufactured and fully supported.

The ERJ-1TNF2260U (Panasonic) carries a "Not For New Designs" status and should be used only for legacy design maintenance or existing production continuity where the original specification requires this specific part number.

All four parts carry identical electrical specifications, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, making them functionally interchangeable at the circuit level. Selection may be based on supplier availability, lead time, inventory position, or established supply chain relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S1TF2260U be replaced with ERJ-1TNF2260U in new designs?

A: No. ERJ-1TNF2260U carries "Not For New Designs" status. Use ERJ-S1TF2260U, AC2512FK-07226RL, or CRCW2512226RFKEG for new designs.

Q: Are there any dimensional differences between substitute parts?

A: Yes. Length ranges from 6.30mm to 6.40mm, width from 3.10mm to 3.20mm, and height from 0.65mm to 0.70mm across the four parts. These variations fall within standard PCB assembly tolerances and do not affect circuit performance or board layout compatibility.

Q: Do all substitute parts meet automotive requirements?

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

Q: What is the difference between ERJ-S1TF2260U and AC2512FK-07226RL?

A: Both are electrically identical 226 Ohms ±1% 1W resistors in 2512 package with AEC-Q200 rating. ERJ-S1TF2260U features anti-sulfur coating; AC2512FK-07226RL features moisture-resistant coating. Both are active products from different manufacturers.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts share identical electrical parameters, package footprint compatibility, and compliance certifications. They can be used interchangeably in the same circuit design.

Q: Which part should I choose for highest availability?

A: ERJ-1TNF2260U has the highest inventory (11973 pcs), followed by CRCW2512226RFKEG (6959 pcs) and AC2512FK-07226RL (2751 pcs). However, for new designs, choose from active status parts: CRCW2512226RFKEG or AC2512FK-07226RL.
