Substitute Part Grouping Explanation

Substitution eligibility for the IM02EB6R8K is determined by the following critical parameters:

• Inductance Value: 6.8 µH (exact match required)
• Tolerance: ±10% (exact match required)
• DC Resistance: 2Ohm Max (exact match required)
• Current Rating: Minimum 175 mA (equal or higher acceptable)
• Core Material: Iron (exact match required)
• Shielding: Unshielded (exact match required)
• Mounting Type: Through Hole Axial (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Physical Dimensions: 0.095" Dia x 0.250" L (exact match required)

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 1025R-40K (API Delevan Inc.)

The 1025R-40K is the preferred substitute for the obsolete IM02EB6R8K. This part maintains all critical electrical and mechanical specifications while offering a higher current rating of 185 mA, providing additional design margin. The 1025R-40K is actively manufactured, ROHS3 compliant, and available in bulk packaging. Inventory availability is confirmed at 1025 pieces.

Alternative Substitutes: ER1025-40KM and ER1025-40KP (API Delevan Inc.)

Both ER1025-40KM and ER1025-40KP are manufacturer-recommended alternatives from API Delevan Inc. These parts are actively produced and available in Tape & Reel packaging. However, both variants are RoHS non-compliant, which may restrict their use in applications requiring RoHS3 certification. Selection between these options depends on packaging requirements and compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-40K directly replace the IM02EB6R8K in existing designs?

A: Yes. The 1025R-40K maintains identical inductance (6.8 µH), tolerance (±10%), DC resistance (2Ohm Max), shielding (unshielded), core material (iron), mounting type (through hole axial), operating temperature range (-55°C ~ 105°C), and physical dimensions (0.095" Dia x 0.250" L). The higher current rating (185 mA vs. 175 mA) provides additional operational margin without affecting circuit performance.

Q: What is the difference between 1025R-40K and ER1025-40KM/ER1025-40KP?

A: The primary differences are packaging format and RoHS compliance status. The 1025R-40K is supplied in bulk packaging and is ROHS3 compliant. The ER1025-40KM and ER1025-40KP are supplied in Tape & Reel format and are RoHS non-compliant. All three parts are electrically and mechanically equivalent for the specified application parameters.

Q: Are there any physical installation differences between these substitutes?

A: No. All substitute parts share identical physical dimensions (0.095" Dia x 0.250" L / 2.41mm x 6.35mm) and through-hole axial mounting configuration. Direct mechanical substitution is possible without PCB layout modifications.

Q: Which substitute should be selected for RoHS-compliant applications?

A: The 1025R-40K is the only ROHS3 compliant option among the listed substitutes. Applications requiring RoHS certification must use this part number.

Q: What is the significance of the current rating difference between 1025R-40K (185 mA) and the original IM02EB6R8K (175 mA)?

A: The 1025R-40K supports a higher maximum current rating, which provides additional design margin and operational headroom. This does not affect compatibility; the part can be used in circuits designed for the lower 175 mA rating without performance degradation.
