ERJ-S1TF3601U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF3601U is a 3.6 kOhms ±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 1118 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF3601U is determined by strict equivalence across the following parameters:

• Resistance value: 3.6 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

The ERJ-1TNF3601U qualifies as a direct substitute, meeting all electrical and mechanical parameters. This part differs only in product status (Not For New Designs) and the absence of anti-sulfur coating specification in its detailed description, though it maintains full AEC-Q200 automotive qualification and identical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF3601U is the preferred selection for new designs due to its active production status. The ERJ-1TNF3601U remains electrically and mechanically equivalent and maintains full AEC-Q200 automotive qualification; however, its "Not For New Designs" status indicates Panasonic's transition away from this series in favor of the ERJ-S1T series.

For applications requiring long-term supply assurance and design continuity, the ERJ-S1TF3601U should be specified. The ERJ-1TNF3601U may be considered for legacy system maintenance or when existing inventory is available, provided that supply chain planning accounts for its discontinued design status.

Both parts satisfy identical compliance requirements: ROHS3 compliance, REACH unaffected status, and AEC-Q200 automotive qualification for -55°C to 155°C operating environments.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF3601U be used as a direct replacement for ERJ-S1TF3601U in automotive applications?

A: Yes. Both parts meet identical electrical specifications (3.6 kOhms ±1%, 1W), operate across the same temperature range (-55°C ~ 155°C), and carry AEC-Q200 automotive qualification. Physical dimensions and package type (2512) are identical, enabling direct PCB substitution. The primary consideration is product status: ERJ-1TNF3601U is not recommended for new designs.

Q: What is the significance of the anti-sulfur coating on the ERJ-S1TF3601U?

A: The anti-sulfur feature is specified in the ERJ-S1TF3601U detailed description but not explicitly listed for the ERJ-1TNF3601U. Both parts maintain AEC-Q200 qualification. Consult Panasonic datasheets for specific environmental protection specifications if sulfur resistance is a critical design requirement.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both parts specify identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C). No frequency-dependent parameters are provided in the specifications.

Q: Can these 2512 package resistors be used interchangeably with other package sizes?

A: No. The 2512 (6432 Metric) package is specific to these parts. Substitution with different package sizes requires PCB layout modification and re-qualification. Package dimensions are 0.252" L x 0.126" W (6.40mm x 3.20mm) with maximum seated height of 0.028" (0.70mm).

Q: What is the moisture sensitivity implication of MSL 1 rating?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly, simplifying supply chain and manufacturing processes.
