Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC780-225K is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Inductance value (2.2 mH), inductance tolerance (±10%), current rating (800 mA), saturation current (2.3 A), and DC resistance (1.54 Ohm maximum) must remain identical.

Physical Parameters: Core material (ferrite), shielding configuration (unshielded), mounting type (through hole), and package geometry (radial, vertical cylinder with 0.772" diameter and 0.831" maximum height) must match exactly.

Environmental Parameters: Operating temperature range (-55°C to 125°C) and inductance test frequency (1 kHz) must be maintained.

Mechanical Compatibility: The substitute part must fit within the same PCB footprint and mounting hole configuration as the original component.

The DC780R-225K qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence across all specified criteria.

Parameter Comparison

Engineering Selection Recommendations

The DC780R-225K serves as a direct electrical and mechanical substitute for the DC780-225K. Both components are manufactured by API Delevan Inc. and maintain identical specifications across all critical electrical parameters, physical dimensions, and operating conditions.

The primary distinction between these parts is regulatory compliance status. The DC780-225K is RoHS non-compliant, while the DC780R-225K is ROHS3 compliant. Selection between these parts should be based on the regulatory requirements of the end application and target market. Applications requiring RoHS3 compliance must use the DC780R-225K. Applications without RoHS compliance requirements may use either part based on availability and supply chain considerations.

Both components are currently in active production with adequate inventory levels. The DC780R-225K maintains higher stock availability (1843 pieces) compared to the DC780-225K (1087 pieces).

Frequently Asked Questions (FAQ)

Q: Can the DC780R-225K be used as a direct replacement for the DC780-225K in all applications?

A: Yes, from an electrical and mechanical standpoint. The DC780R-225K is electrically and physically identical to the DC780-225K. The only difference is RoHS3 compliance status. Substitution is valid for applications where RoHS compliance is not a requirement or where RoHS3 compliance is required.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in inductance value (2.2 mH), inductance tolerance (±10%), current rating (800 mA), saturation current (2.3 A), DC resistance (1.54 Ohm maximum), core material (ferrite), shielding configuration (unshielded), mounting type (through hole), package geometry (radial, vertical cylinder), physical dimensions (0.772" diameter, 0.831" maximum height), and operating temperature range (-55°C to 125°C).

Q: Are there any physical footprint differences between the DC780-225K and DC780R-225K?

A: No. Both components have identical physical dimensions: 0.772 inches (19.60 mm) diameter and 0.831 inches (21.10 mm) maximum height. Both use radial, vertical cylinder package configuration with through-hole mounting. PCB footprints are interchangeable.

Q: What is the significance of the RoHS compliance difference?

A: The DC780R-225K is ROHS3 compliant, while the DC780-225K is RoHS non-compliant. This distinction is relevant only for applications subject to RoHS regulations. Applications targeting markets with RoHS requirements must use the DC780R-225K. For applications without RoHS compliance mandates, either part is functionally equivalent.

Q: Are both parts currently available?

A: Yes. Both the DC780-225K and DC780R-225K are in active production status. The DC780R-225K has higher current inventory (1843 pieces) compared to the DC780-225K (1087 pieces).

Q: What is the inductance tolerance for these components?

A: Both components have an inductance tolerance of ±10% at the 1 kHz test frequency. This tolerance applies equally to the DC780-225K and DC780R-225K.

Q: Can these inductors be used in high-temperature applications?

A: Yes. Both the DC780-225K and DC780R-225K are rated for operation across the temperature range of -55°C to 125°C, making them suitable for extended temperature applications within this range.
