ERJ-S1DF2401U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF2401U is a 2.4 kOhms ±1% 0.75W chip resistor manufactured by Panasonic Electronic Components in the 2010 (5025 Metric) package. This thick film resistor features anti-sulfur properties and automotive AEC-Q200 qualification, making it suitable for automotive and industrial applications requiring high reliability. The part is currently active in production with 1,075 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to supply constraints, design flexibility, or application-specific feature requirements.

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF2401U are qualified based on the following criteria:

• Identical resistance value: 2.4 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.75W (3/4W)
• Identical package: 2010 (5025 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

All substitute parts meet these core electrical and mechanical specifications. Variations in secondary features such as anti-sulfur properties or specific automotive certifications do not disqualify substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with ROHS3 compliance and MSL 1 ratings, confirming their suitability for direct substitution in applications requiring the ERJ-S1DF2401U specifications.

CRCW20102K40FKEF (Vishay Dale) and RMCF2010FT2K40 (Stackpole Electronics Inc) both carry AEC-Q200 automotive qualification, matching the primary part's automotive-grade specification. These options are preferred for applications requiring automotive-grade reliability assurance.

RC2010FK-072K4L (YAGEO) features moisture-resistant properties without explicit AEC-Q200 designation. This part remains electrically and mechanically equivalent and is suitable for non-automotive applications or where moisture resistance is the primary secondary requirement.

All substitute parts maintain identical electrical performance across resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Physical dimensions are equivalent with negligible height variation (0.026" to 0.028" seated height), confirming PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW20102K40FKEF replace ERJ-S1DF2401U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (2.4 kOhms ±1%, 0.75W), and use the 2010 package. They are electrically and mechanically interchangeable.

Q: What is the difference between RC2010FK-072K4L and the other substitutes?

A: RC2010FK-072K4L features moisture-resistant properties instead of anti-sulfur or explicit AEC-Q200 designation. All electrical parameters remain identical. The seated height is 0.026" versus 0.028" for other parts, a difference of 0.002" that does not affect PCB layout compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts, including the primary ERJ-S1DF2401U, are ROHS3 compliant with MSL 1 (Unlimited) ratings.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts share the 2010 (5025 Metric) package with identical length and width (0.197" x 0.098"). Seated height variation is minimal (0.002" maximum difference) and does not affect standard PCB assembly processes.

Q: Which substitute offers the best availability?

A: CRCW20102K40FKEF (Vishay Dale) has the highest inventory at 10,483 units in stock, followed by RC2010FK-072K4L (YAGEO) at 8,798 units and RMCF2010FT2K40 (Stackpole) at 4,553 units.
