IMS05ER680K Equivalent & Substitute Parts

Part Overview

The IMS05ER680K is a 68 µH shielded molded inductor manufactured by Vishay Dale, designed for through-hole applications requiring moderate current handling at 170 mA with a maximum DC resistance of 2.7 Ohm. This component belongs to the IMS-5 series and is suitable for filtering, energy storage, and signal conditioning circuits in consumer and industrial electronics.

Equivalent parts are necessary when the primary manufacturer's stock is unavailable, when supply chain optimization is required, or when design flexibility across qualified alternatives is needed to meet production schedules and cost objectives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMS05ER680K is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance Value: 68 µH (primary electrical specification)
• Current Rating: 170 mA minimum (functional requirement for circuit operation)
• DC Resistance: 2.7 Ohm maximum (power loss and thermal performance)
• Shielding: Shielded construction (electromagnetic interference mitigation)
• Mounting Configuration: Through-hole axial package (mechanical compatibility)
• Core Material: Ferrite (frequency response and saturation characteristics)

The Bourns Inc. 9250A-683-RC meets all these criteria and qualifies as a direct equivalent. Both parts share identical electrical specifications and physical form factors, enabling pin-for-pin substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-683-RC from Bourns Inc. is qualified as a direct substitute for the IMS05ER680K based on electrical and mechanical parameter equivalence. The Bourns component carries active product status and meets ROHS3 compliance and REACH regulatory requirements, ensuring long-term availability and environmental conformance for production applications.

Selection between the primary part and substitute should be based on inventory availability, lead time requirements, and procurement cost optimization. Both components are suitable for identical circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-683-RC replace the IMS05ER680K in existing designs?

A: Yes. Both inductors share identical inductance (68 µH), current rating (170 mA), DC resistance (2.7 Ohm max), shielding configuration, and through-hole axial package. No circuit redesign is required.

Q: Are there physical dimension differences between these parts?

A: The 9250A-683-RC is specified at 0.162" diameter × 0.410" length (4.11mm × 10.41mm). Physical dimensions for the IMS05ER680K are not provided in the available data. Verify PCB layout compatibility before substitution if space constraints are critical.

Q: What is the tolerance specification for the IMS05ER680K?

A: Tolerance data for the IMS05ER680K is not provided. The 9250A-683-RC carries ±10% inductance tolerance. Confirm tolerance requirements with the original design specification before substitution.

Q: Are both parts suitable for high-frequency applications?

A: The 9250A-683-RC specifies a self-resonant frequency of 21 MHz and Q factor of 50 at 2.5 MHz. Frequency response data for the IMS05ER680K is not available. Evaluate frequency-dependent performance requirements against the Bourns specification if operation above 2.5 MHz is required.

Q: What is the saturation current for the IMS05ER680K?

A: Saturation current (Isat) for the IMS05ER680K is not specified. The 9250A-683-RC specifies 150 mA saturation current. Confirm saturation performance requirements with the original design if peak current handling is a critical parameter.

Q: Do both parts meet environmental and regulatory requirements?

A: The 9250A-683-RC is ROHS3 compliant and REACH unaffected. Regulatory compliance data for the IMS05ER680K is not provided. Verify compliance requirements with your procurement or quality assurance department before substitution.
