ERJ-S1DF4023U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF4023U is a 402 kOhms ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) package. Manufactured by Panasonic Electronic Components, this component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently in active production status with 747 units in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits equivalent alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF4023U is determined by strict equivalence across the following parameters:

• Resistance value: 402 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Package: 2010 (5025 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 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria without exception. Substitution does not require design modification, PCB layout changes, or thermal management adjustments.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1DF4023U (Panasonic, Active status) or CRCW2010402KFKEF (Vishay Dale, Active status) are the preferred selections. Both components carry active product status and ensure long-term availability and supply chain stability.

The ERJ-12SF4023U, while electrically and mechanically equivalent, carries a "Not For New Designs" status. This part remains suitable for replacement, repair, and legacy system applications where the original component specification must be maintained. Selection of this part for new designs is not recommended due to its discontinued design status.

All three parts satisfy automotive AEC-Q200 qualification and ROHS3 compliance requirements. Selection between active-status alternatives depends on supplier availability, lead time, and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF4023U be used as a direct replacement for ERJ-S1DF4023U in new designs?

A: ERJ-12SF4023U meets all electrical and mechanical specifications for direct substitution. However, it carries "Not For New Designs" status. For new designs, select an active-status alternative such as CRCW2010402KFKEF.

Q: Are all substitute parts automotive-qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C ~ 155°C).

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use the identical 2010 (5025 Metric) package with matching footprint dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm) and height (0.028" maximum seated height).

Q: What is the difference between Panasonic ERJ-S1DF and ERJ-12SF series?

A: Both series are thick film 402 kOhms ±1% resistors in 2010 packages with identical electrical performance. The ERJ-S1D series includes anti-sulfur coating. The ERJ-12S series does not specify anti-sulfur treatment. The ERJ-12SF series is designated "Not For New Designs."

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can I mix manufacturers in the same assembly?

A: Yes. All substitute parts meet identical specifications and certifications. Mixed-manufacturer assemblies are permissible from an electrical and mechanical standpoint.
