Substitute Part Grouping Explanation

Substitution of the ELC-09D332DF is determined by the following critical parameters:

• Inductance Value: 3.3 mH (±10% tolerance)
• Current Rating: Minimum 140 mA
• DC Resistance: Maximum 7 Ohm (lower values acceptable)
• Mounting Type: Through Hole
• Package Configuration: Radial, Vertical Cylinder
• Shielding: Unshielded
• Compliance: ROHS3 Compliant

The RL895-332K-RC from Bourns Inc. meets all substitution criteria within these electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The RL895-332K-RC is a direct functional substitute for the ELC-09D332DF. Both components are ROHS3 compliant and meet the electrical specifications required for 3.3 mH inductance applications at 140 mA operation. The Bourns component offers improved availability as an active product and provides superior DC resistance performance (6.16 Ohm Max versus 7 Ohm). The RL895-332K-RC is suitable for direct replacement in through-hole PCB applications where the ELC-09D332DF was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the RL895-332K-RC replace the ELC-09D332DF in existing designs?

A: Yes. Both components share identical inductance values (3.3 mH), matching tolerance (±10%), and unshielded through-hole radial configuration. The RL895-332K-RC exceeds the current rating requirement (150 mA versus 140 mA) and provides lower DC resistance (6.16 Ohm Max versus 7 Ohm).

Q: Are there physical compatibility concerns?

A: The RL895-332K-RC has a smaller diameter (0.307" versus 0.374") but slightly greater height (0.374" versus 0.350"). PCB layout verification is required to confirm clearance in the vertical dimension and to confirm the reduced diameter does not affect mechanical retention or electrical connectivity.

Q: Do both parts meet compliance requirements?

A: Yes. Both the ELC-09D332DF and RL895-332K-RC are ROHS3 compliant. The RL895-332K-RC is additionally REACH Unaffected.

Q: What is the inductance tolerance range for these parts?

A: Both components have ±10% tolerance on the 3.3 mH nominal value, resulting in an acceptable range of 2.97 mH to 3.63 mH.

Q: Why is the ELC-09D332DF obsolete?

A: The ELC-09D332DF is classified as obsolete by the manufacturer. The RL895-332K-RC from Bourns is an active product with current manufacturing support and inventory availability.
