IHB4EB102K Equivalent & Substitute Parts

Part Overview

The IHB4EB102K is a 1 mH unshielded wirewound inductor manufactured by Vishay Dale, rated for 3.3 A continuous current with a maximum DC resistance of 216 mOhm. This radial, vertical cylinder through-hole component is designed for applications requiring fixed inductance in standard PCB configurations. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design continuity when the primary part becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the IHB4EB102K are qualified based on the following critical parameters:

• Inductance Value: Must be 1 mH (±10% tolerance acceptable)
• Current Rating: Must meet or exceed 3.3 A continuous rating
• DC Resistance: Must not exceed 216 mOhm maximum
• Shielding Configuration: Unshielded topology required
• Mounting Technology: Through-hole radial package mandatory
• Core Type: Wirewound construction with ferrite or equivalent core material

The substitute part 1140-102K-RC from Bourns Inc. meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 1140-102K-RC from Bourns Inc. is a direct substitute for the IHB4EB102K based on electrical and mechanical compatibility. The substitute part provides equal or superior performance across all critical parameters: identical inductance value, higher current rating (3.6 A vs. 3.3 A), matching DC resistance specification, and identical through-hole radial package configuration.

The Bourns part carries active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The specified operating temperature range of -55°C to 105°C and ±10% inductance tolerance provide documented performance boundaries suitable for standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1140-102K-RC be used as a direct replacement for the IHB4EB102K?

A: Yes. Both parts share identical inductance (1 mH), DC resistance (216 mOhm Max), shielding configuration (unshielded), and through-hole radial package format. The Bourns part exceeds the current rating requirement (3.6 A vs. 3.3 A), making it electrically and mechanically compatible.

Q: What are the key differences between these two inductors?

A: The primary differences are manufacturer identity and core construction detail. The Bourns 1140-102K-RC uses drum core wirewound construction versus the Vishay Dale vertical cylinder design. Both achieve identical electrical specifications. The Bourns part provides documented saturation current (6.5 A) and operating temperature range (-55°C ~ 105°C), which are not specified for the Vishay part.

Q: Are there any package or footprint concerns when substituting?

A: No. Both parts are specified as radial through-hole components with identical package classification. Physical dimensions (1.500" diameter, 1.030" height seated) are provided for the Bourns part and should be verified against PCB layout requirements, but the radial package type ensures compatibility with standard through-hole mounting.

Q: What compliance certifications apply to the substitute part?

A: The 1140-102K-RC is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial electronics applications.
