Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF3900U are qualified based on strict equivalence of the following parameters: resistance value (390 Ohms), tolerance (±1%), power rating (0.75W), package type (2010 / 5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH Unaffected, EAR99). All identified substitutes maintain these core electrical and mechanical specifications. Variations in secondary features such as anti-sulfur versus moisture-resistant properties do not affect functional interchangeability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS3 compliance. The ERJ-S1DF3900U and CRCW2010390RFKEF both carry explicit AEC-Q200 automotive qualification, making them directly interchangeable for automotive applications. The RC2010FK-07390RL meets all electrical and mechanical specifications but does not list AEC-Q200 certification; selection of this part should be confirmed against specific application requirements. All parts are REACH Unaffected and classified as EAR99 for export control purposes. Inventory availability varies: Panasonic (938 units), Vishay Dale (5,198 units), and YAGEO (7,360 units).

Frequently Asked Questions (FAQ)

Q: Can CRCW2010390RFKEF replace ERJ-S1DF3900U in automotive applications? A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (390 Ohms ±1%, 0.75W, ±100ppm/°C) and package dimensions (2010 / 5025 Metric). Direct substitution is supported.

Q: Is RC2010FK-07390RL suitable for automotive use? A: RC2010FK-07390RL meets all electrical and mechanical parameters of the ERJ-S1DF3900U but does not specify AEC-Q200 certification. Confirmation against application-specific automotive requirements is necessary before selection.

Q: What is the difference between anti-sulfur and moisture-resistant features? A: The ERJ-S1DF3900U includes anti-sulfur properties; the RC2010FK-07390RL specifies moisture resistance. Both are secondary features that do not affect core electrical performance or interchangeability within the defined parameter set.

Q: Are all three parts available in Tape & Reel packaging? A: Yes. All parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Q: Do the parts differ in physical height? A: The ERJ-S1DF3900U and CRCW2010390RFKEF have maximum seated height of 0.028" (0.70mm). The RC2010FK-07390RL has maximum seated height of 0.026" (0.65mm). Both heights are within typical PCB assembly tolerances for 2010 package components.

Q: Are all parts RoHS3 compliant? A: Yes. All three parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).
