ERJ-S1TF1580U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF1580U is a 158 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 in active production status with 857 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same package footprint and performance specifications. Alternative sources may be required due to supply availability, design phase transitions, or procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1580U is determined by strict equivalence across the following parameters:

• Resistance value: 158 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package footprint: 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

Two substitute parts meet these criteria and are listed below. Both maintain identical electrical performance and mechanical compatibility with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S1TF1580U (Primary Part): Active production status with anti-sulfur coating feature. Recommended for new designs and long-term supply continuity. Current inventory: 857 units.

ERJ-1TNF1580U (Panasonic Substitute): Functionally equivalent with identical electrical and mechanical specifications. Marked as "Not For New Designs," indicating this part is in mature or transitional production phase. Suitable for legacy system maintenance or existing design support. Higher inventory availability: 6030 units.

RMCF2512FT158R (Stackpole Substitute): Active production status from alternative manufacturer. Meets all electrical and mechanical equivalence criteria. Dimension variance of 0.004" in length (6.30mm vs 6.40mm) remains within standard PCB footprint tolerances for 2512 package. Inventory: 4473 units.

All three parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Selection between active-status parts (ERJ-S1TF1580U and RMCF2512FT158R) depends on supply chain strategy and manufacturer preference.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1580U be used as a direct replacement for ERJ-S1TF1580U?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance, tolerance, power rating, package, temperature coefficient, and operating range. However, ERJ-1TNF1580U carries "Not For New Designs" status, indicating it is not recommended for new product development. Use this part only for maintenance of existing systems or legacy design support.

Q: What is the significance of the anti-sulfur coating on ERJ-S1TF1580U?

A: The anti-sulfur feature on ERJ-S1TF1580U is specified in the product data. ERJ-1TNF1580U does not list this feature. RMCF2512FT158R does not specify anti-sulfur coating. If anti-sulfur protection is a design requirement, ERJ-S1TF1580U is the appropriate selection.

Q: Are there dimensional differences between the substitute parts?

A: RMCF2512FT158R has a length of 6.30mm compared to 6.40mm for both Panasonic parts. This 0.10mm difference is within standard PCB footprint tolerance for 2512 package components and does not affect board-level compatibility. All parts maintain identical width (3.20mm) and height (0.70mm).

Q: Which substitute part should be selected for new automotive designs?

A: For new designs, select between ERJ-S1TF1580U (primary, active status, anti-sulfur) or RMCF2512FT158R (active status, alternative manufacturer). Both maintain active production and full AEC-Q200 qualification. ERJ-1TNF1580U should not be used for new designs due to its "Not For New Designs" status.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for automotive and industrial applications.
