ERJ-S1TF24R3U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF24R3U is a 24.3 Ohms ±1% 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 active in production with 894 pieces in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative manufacturers, or when supply chain optimization requires qualified alternatives from different vendors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF24R3U is determined by the following critical parameters:

• Resistance value: 24.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 Compliant (required for regulatory compliance)

All qualified substitutes meet these parameters across manufacturers including Panasonic Electronic Components, YAGEO, and Vishay Dale.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1TF24R3U (Panasonic), AC2512FK-0724R3L (YAGEO), or CRCW251224R3FKEG (Vishay Dale). All three are ROHS3 compliant and AEC-Q200 qualified.

The ERJ-1TNF24R3U (Panasonic) carries a "Not For New Designs" status and should be used only for legacy design maintenance or when existing inventory constraints require it.

All qualified substitutes maintain identical electrical specifications, operating temperature range, and automotive qualification requirements. Physical dimensions vary slightly within acceptable tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF24R3U be used as a direct replacement for ERJ-S1TF24R3U?

A: Electrically and mechanically, yes. However, ERJ-1TNF24R3U is marked "Not For New Designs." For new applications, use active-status alternatives.

Q: What is the difference between the anti-sulfur feature in ERJ-S1TF24R3U and the moisture-resistant feature in AC2512FK-0724R3L?

A: Both are protective coatings for thick film resistors in automotive environments. The specific coating type is a manufacturing feature; both parts meet AEC-Q200 requirements and operate identically within specified parameters.

Q: Are physical dimensions identical across all substitutes?

A: All parts use the 2512 (6432 Metric) package. Seated height and length/width dimensions vary slightly (within 0.002" to 0.004") but remain within standard 2512 package tolerances and are PCB-compatible.

Q: Which substitute has the highest inventory availability?

A: ERJ-1TNF24R3U has 7916 pieces in stock. For active-status parts, AC2512FK-0724R3L has 4896 pieces available.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected.
