IM02EB1R0K Equivalent & Substitute Parts

Part Overview

The IM02EB1R0K is a 1 µH unshielded molded inductor manufactured by Vishay Dale, rated for 385 mA with a maximum DC resistance of 1 Ohm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across a temperature range of -55°C to 125°C and is ROHS3 compliant. Substitute parts must maintain electrical equivalence in inductance value, current rating, and DC resistance while accommodating packaging and compliance variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IM02EB1R0K are selected based on the following critical parameters:

• Inductance Value: 1 µH (exact match required)
• Tolerance: ±10% (exact match required)
• Current Rating: Minimum 385 mA (equal or higher acceptable)
• DC Resistance: Maximum 1 Ohm (equal or lower acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Operating Temperature Range: Minimum -55°C to 125°C coverage (equal or broader acceptable)
• Shielding: Unshielded or shielded (both acceptable for electrical equivalence)

The substitute parts listed below meet these electrical and mechanical criteria, though variations in product status, compliance certifications, and packaging format exist.

Parameter Comparison

Engineering Selection Recommendations

1025R-20K (API Delevan Inc.)

This part is the closest direct substitute. It maintains identical electrical specifications to the IM02EB1R0K with a marginally higher current rating of 390 mA versus 385 mA. The operating temperature range matches exactly at -55°C to 125°C. ROHS3 compliance is maintained. The part is active and available in bulk packaging. Physical dimensions are identical. This part is suitable for direct replacement in applications requiring ROHS3 compliance and full temperature range coverage.

ER1025-20KM and ER1025-20KP (API Delevan Inc.)

Both parts are manufacturer-recommended alternatives with identical electrical specifications to the original part. However, the operating temperature range is reduced to -55°C to 105°C, which does not cover the full upper temperature specification of the original part. Both parts are RoHS non-compliant. These parts are available in Tape & Reel packaging. Selection of these parts is appropriate only when the reduced temperature range and RoHS non-compliance status are acceptable for the application.

SC301R0KT (TE Connectivity Passive Product)

This part offers the highest current rating at 420 mA and maintains all critical electrical parameters. However, it features shielded construction compared to the unshielded original, resulting in a larger physical footprint (0.165" Dia x 0.394" L versus 0.095" Dia x 0.250" L). The operating temperature range is limited to -55°C to 100°C. ROHS3 compliance is maintained. This part is suitable for applications where the increased physical size is acceptable and the reduced temperature range meets requirements. The shielded design may provide benefits in noise-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can I use SC301R0KT as a direct replacement for IM02EB1R0K?

A: SC301R0KT is electrically equivalent in inductance, tolerance, DC resistance, and Q factor. However, it has a larger physical footprint (0.165" Dia x 0.394" L versus 0.095" Dia x 0.250" L) and a reduced maximum operating temperature of 100°C instead of 125°C. PCB layout verification is required before substitution.

Q: Which substitute part maintains full ROHS3 compliance?

A: Both 1025R-20K and SC301R0KT are ROHS3 compliant. ER1025-20KM and ER1025-20KP are RoHS non-compliant.

Q: What is the difference between the ER1025-20KM and ER1025-20KP parts?

A: Both parts are electrically and mechanically identical. The difference lies in packaging format: ER1025-20KM is supplied in Tape & Reel (TR) format, while ER1025-20KP is also supplied in Tape & Reel (TR) format. Both are RoHS non-compliant and have a reduced operating temperature range of -55°C to 105°C.

Q: Is the shielded SC301R0KT suitable for my application if the original was unshielded?

A: Shielding affects electromagnetic coupling and noise characteristics. SC301R0KT is electrically equivalent in inductance and DC resistance but will exhibit different shielding behavior. Application-specific testing may be necessary to confirm suitability, particularly in noise-sensitive circuits.

Q: What is the impact of the reduced temperature range in ER1025 parts?

A: ER1025-20KM and ER1025-20KP operate to a maximum of 105°C instead of 125°C. If your application requires operation at temperatures above 105°C, these parts are not suitable. The 1025R-20K or SC301R0KT should be selected instead.

Q: Can I mix packaging formats in my procurement?

A: Yes. 1025R-20K is available in Bulk, ER1025-20KM and ER1025-20KP in Tape & Reel (TR), and SC301R0KT in Cut Tape (CT). Packaging format does not affect electrical performance and can be selected based on assembly requirements and inventory management preferences.
