IMS05STR68K Equivalent & Substitute Parts

Part Overview

The IMS05STR68K is a 680 nH shielded molded inductor manufactured by Vishay Dale, designed for through-hole mounting applications requiring fixed inductance with moderate current handling. This component belongs to the IMS-5 series and is specified for 420 mA operation with a maximum DC resistance of 450 mOhm. The part is currently in stock with 935 units available as new original inventory.

Equivalent and substitute parts are identified when they maintain identical or functionally equivalent electrical and mechanical specifications within the allowed tolerance ranges for this inductor category. Substitutes enable procurement flexibility, supply chain continuity, and design optimization across compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMS05STR68K are qualified based on the following critical parameters:

• Inductance Value: 680 nH (primary electrical specification)
• Current Rating: 420 mA minimum (current handling capability)
• DC Resistance: 450 mOhm maximum (power loss and thermal characteristics)
• Shielding: Shielded construction (electromagnetic interference control)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: Axial (form factor and PCB layout compatibility)

The substitute part 9250A-681-RC from Bourns Inc. meets all these critical parameters and is therefore electrically and mechanically interchangeable with the IMS05STR68K.

Parameter Comparison

Engineering Selection Recommendations

Both the IMS05STR68K and 9250A-681-RC are active production components with identical electrical specifications for inductance, current rating, and DC resistance. The 9250A-681-RC carries ROHS3 compliance certification, which may be required for applications subject to regulatory restrictions on hazardous substances.

Selection between these parts should be based on:

• Supply availability: Choose based on inventory status and lead time requirements
• Regulatory compliance: The 9250A-681-RC is explicitly ROHS3 compliant
• Packaging preference: Both are supplied in axial through-hole format; verify packaging quantity requirements (Vishay Dale: -; Bourns Inc.: Bulk)
• Procurement source: Verify part availability through your established component suppliers

Frequently Asked Questions (FAQ)

Q: Can the 9250A-681-RC replace the IMS05STR68K in my circuit?

A: Yes. Both inductors share identical inductance (680 nH), current rating (420 mA), DC resistance (450 mOhm max), shielding, and axial through-hole package specifications. They are electrically and mechanically interchangeable.

Q: What are the key parameters that determine substitutability?

A: The critical parameters are inductance value (680 nH), current rating (420 mA), maximum DC resistance (450 mOhm), shielded construction, and through-hole axial package format. Any substitute must match or exceed these specifications.

Q: Does the ±10% tolerance on the 9250A-681-RC affect compatibility?

A: The ±10% inductance tolerance on the 9250A-681-RC is a manufacturing specification. Provided the part is within this tolerance band at the time of measurement, it meets the 680 nH inductance requirement for circuit operation.

Q: Are there any compliance differences between these parts?

A: The 9250A-681-RC is certified ROHS3 compliant. Compliance status for the IMS05STR68K is not specified in the available data. Verify compliance requirements for your specific application.

Q: What is the difference between the IMS-5 and 9250A series designations?

A: These are manufacturer-specific series identifiers. IMS-5 is the Vishay Dale series designation, while 9250A is the Bourns Inc. series designation. Both series contain inductors with identical electrical and mechanical specifications for this substitution.
