HCTI-560-3.6 Equivalent & Substitute Parts

Part Overview

The HCTI-560-3.6 is a 560 µH shielded toroidal inductor manufactured by Signal Transformer, rated for 3.6 A continuous current with a maximum DC resistance of 140 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is ROHS3 compliant. The part is currently active in production with 682 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCTI-560-3.6 are qualified based on the following electrical and mechanical parameters:

• Inductance value: 560 µH with ±15% tolerance
• Current rating: 3.6 A minimum
• DC resistance: 140 mOhm maximum
• Operating temperature range: -55°C to 105°C minimum
• Mounting configuration: Through-hole radial, vertical orientation
• Physical footprint: 1.280" diameter x 0.650" width (32.51mm x 16.51mm)
• Regulatory compliance: ROHS3 compliant

The substitute part 2321-V-RC from Bourns Inc. meets all specified electrical parameters and physical constraints. The primary difference is the shielding configuration: the HCTI-560-3.6 is shielded, while the 2321-V-RC is unshielded. This distinction affects electromagnetic interference characteristics but does not alter the core electrical performance metrics required for substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the HCTI-560-3.6 and 2321-V-RC are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on shielding requirements specific to the application. The HCTI-560-3.6 provides electromagnetic shielding, suitable for noise-sensitive circuits. The 2321-V-RC offers an unshielded alternative with identical electrical specifications and physical footprint. Both parts satisfy the specified inductance, current, resistance, and temperature operating parameters. Inventory availability may also influence part selection, with 1013 units of the 2321-V-RC currently in stock compared to 682 units of the HCTI-560-3.6.

Frequently Asked Questions (FAQ)

Q: Can the 2321-V-RC replace the HCTI-560-3.6 in all applications?

A: The 2321-V-RC matches all electrical parameters and physical dimensions. The primary difference is shielding. Applications requiring electromagnetic shielding must retain the HCTI-560-3.6. Applications without shielding requirements can use the 2321-V-RC.

Q: What is the impact of the shielding difference?

A: Shielding reduces electromagnetic interference emission and susceptibility. The shielded HCTI-560-3.6 is preferred in noise-sensitive circuits. The unshielded 2321-V-RC is suitable for general-purpose applications where EMI is not a design constraint.

Q: Are the physical footprints identical?

A: Both parts share identical dimensions of 1.280" diameter x 0.650" width (32.51mm x 16.51mm) in radial, vertical orientation. PCB layout and mounting hole spacing are compatible.

Q: Do both parts meet regulatory requirements?

A: Both the HCTI-560-3.6 and 2321-V-RC are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the tolerance specification for inductance?

A: Both parts carry ±15% inductance tolerance at 1 kHz test frequency. Circuit designs must account for this tolerance range in inductance calculations.
