ERJ-S1TF1402U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF1402U is a 14 kOhms ±1% 1W thick film chip resistor manufactured by Panasonic Electronic Components in the 2512 (6432 Metric) package. This component is rated for automotive applications under AEC-Q200 and features anti-sulfur protection. The part is currently active in production with 917 units in stock. Equivalent parts are necessary when primary inventory is depleted, when supply chain constraints occur, or when design flexibility across qualified suppliers is required for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-S1TF1402U is determined by strict equivalence across the following parameters:

• Resistance value: 14 kOhms
• 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 without exception. Physical dimensions may vary within acceptable tolerances for the 2512 package standard. Substitutes are qualified for direct replacement in automotive applications requiring AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S1TF1402U, CRCW251214K0FKEG, and RMCF2512FT14K0—are functionally equivalent for automotive applications. Selection between them should be based on:

• Inventory availability and lead time requirements
• Supplier qualification status within your organization
• Cost considerations across qualified suppliers
• Existing supply chain relationships

All parts carry active product status, ROHS3 compliance, and AEC-Q200 automotive qualification. Physical dimensions show minor variations within the 2512 package specification (length ranges 6.30–6.40mm, width ranges 3.15–3.20mm, height consistent at 0.70mm maximum). These dimensional tolerances are standard for the package class and do not affect PCB layout or thermal performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW251214K0FKEG or RMCF2512FT14K0 be used as direct replacements for ERJ-S1TF1402U?

A: Yes. Both parts meet all electrical and mechanical specifications required for direct substitution. They share identical resistance, tolerance, power rating, package, temperature coefficient, and operating range. All three carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: Are there any differences in physical dimensions between these parts?

A: Minor dimensional variations exist within the 2512 package standard. The ERJ-S1TF1402U measures 6.40mm × 3.20mm, while CRCW251214K0FKEG measures 6.30mm × 3.15mm, and RMCF2512FT14K0 measures 6.30mm × 3.20mm. All three have a maximum seated height of 0.70mm. These tolerances are within the 2512 specification and do not require PCB redesign.

Q: What is the significance of the anti-sulfur feature on the ERJ-S1TF1402U?

A: The anti-sulfur protection is a feature specific to the Panasonic ERJ-S1TF1402U. The Vishay Dale and Stackpole equivalents do not list this feature in their specifications. If anti-sulfur protection is a design requirement, the ERJ-S1TF1402U should be retained as the primary choice.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification, indicating they meet automotive industry reliability and quality standards. They are suitable for use in automotive circuits operating within the specified temperature range of -55°C to 155°C.

Q: What is Moisture Sensitivity Level 1, and why does it matter?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All three parts have MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures prior to assembly.
