ERJ-S1DF30R0U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF30R0U is a 30 Ohm ±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 798 units in stock. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance ratings are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF30R0U are qualified based on the following criteria:

• Identical resistance value: 30 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.75W
• Same package designation: 2010 (5025 Metric)
• Identical physical dimensions: 0.197" L x 0.098" W
• Matching temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• Equivalent or superior compliance ratings: ROHS3, MSL 1

Two substitute parts meet these criteria: RC2010FK-0730RL (YAGEO) and RMCF2010FT30R0 (Stackpole Electronics Inc). Both maintain full electrical and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full ROHS3 compliance. The ERJ-S1DF30R0U and RMCF2010FT30R0 both carry automotive AEC-Q200 qualification, making them functionally equivalent for automotive applications. The RC2010FK-0730RL from YAGEO provides an alternative with moisture-resistant thick film composition and slightly reduced seated height (0.026" vs 0.028"), which may be advantageous in space-constrained designs. Selection between substitutes should be based on supply availability, lead time requirements, and specific application certifications.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0730RL replace ERJ-S1DF30R0U in automotive applications?

A: RC2010FK-0730RL meets all electrical and mechanical specifications but does not carry AEC-Q200 automotive qualification. Use only if automotive certification is not a design requirement.

Q: Is RMCF2010FT30R0 a direct substitute for ERJ-S1DF30R0U?

A: Yes. RMCF2010FT30R0 matches all electrical parameters, physical dimensions, temperature characteristics, and carries equivalent AEC-Q200 automotive qualification.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All three parts use the 2010 (5025 Metric) package with identical length and width dimensions (0.197" x 0.098"). The RC2010FK-0730RL has a maximum seated height of 0.026" compared to 0.028" for the other two parts, which remains within standard PCB assembly tolerances.

Q: Are all parts RoHS compliant?

A: Yes. ERJ-S1DF30R0U, RC2010FK-0730RL, and RMCF2010FT30R0 are all ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection prevents degradation from sulfur-containing environments common in automotive applications. Moisture-resistant composition protects against humidity exposure. Both are protective features; selection depends on the specific environmental conditions of the application.
