Engineering Selection Recommendations

1025R-60K (API Delevan Inc.) is the primary substitute for the IM02EB470K. This part maintains active product status and ROHS3 compliance, matching the original component's regulatory requirements. It is available in bulk packaging and provides 2798 pieces in current inventory.

ER1025-60KM and ER1025-60KP (API Delevan Inc.) are alternative substitutes from the active ER1025 series. Both parts are available in Tape & Reel packaging for automated assembly processes. Note that these variants are RoHS non-compliant, making them suitable only for applications where RoHS3 compliance is not required. ER1025-60KM provides 1005 pieces in inventory, while ER1025-60KP provides 787 pieces.

Selection between these substitutes depends on packaging requirements (bulk versus tape & reel) and regulatory compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-60K directly replace the IM02EB470K in existing designs? A: Yes. The 1025R-60K matches all electrical and mechanical parameters of the IM02EB470K, including inductance, current rating, DC resistance, frequency characteristics, temperature range, and physical dimensions. No circuit modifications are required.

Q: What is the difference between 1025R-60K and ER1025-60KM/ER1025-60KP? A: The primary differences are packaging format and RoHS compliance status. The 1025R-60K is supplied in bulk packaging and maintains ROHS3 compliance. The ER1025-60KM and ER1025-60KP are supplied in Tape & Reel format for automated assembly but are RoHS non-compliant. All three parts are electrically and mechanically identical.

Q: Why is the original IM02EB470K listed as obsolete? A: Obsolete status indicates the part is no longer manufactured by Vishay Dale. The listed substitute parts from API Delevan Inc. provide equivalent functionality and are actively produced.

Q: Are there any compliance differences between the substitute options? A: Yes. The 1025R-60K maintains ROHS3 compliance matching the original part. The ER1025-60KM and ER1025-60KP are RoHS non-compliant. Select based on your application's regulatory requirements.

Q: Can I use ER1025-60KM or ER1025-60KP in place of 1025R-60K? A: Electrically and mechanically, yes. However, the packaging format differs (Tape & Reel versus bulk), and RoHS compliance status differs. Verify your assembly process requirements and regulatory mandates before substitution.

Q: What are the key parameters that determine substitutability? A: Inductance (47 µH), current rating (110 mA), DC resistance (4.5 Ohm max), tolerance (±10%), core material (ferrite), shielding (unshielded), frequency characteristics (Q @ 2.5 MHz = 45, SRF = 20 MHz), operating temperature range (-55°C ~ 105°C), and physical dimensions (0.095" Dia x 0.250" L) must all match for direct substitution.
