Engineering Selection Recommendations

The 1110-101K-RC (Bourns) is the primary direct substitute. It maintains identical electrical specifications and physical dimensions while offering active product status and RoHS3 compliance, addressing regulatory requirements for new designs and procurement.

The IHB1BV101K and IHB1EB101K (Vishay Dale) are functionally equivalent alternatives. Both parts meet all critical electrical parameters with a current rating of 2.7 A, which is acceptable for applications designed for 2.8 A operation. These parts provide additional sourcing options and maintain compatibility with the original design specifications.

For applications requiring RoHS compliance or long-term availability, the 1110-101K-RC is the recommended primary choice. For applications with flexible sourcing requirements, the Vishay Dale alternatives provide equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1110-101K-RC be used as a direct replacement for the 1110-101K?

A: Yes. The 1110-101K-RC is electrically and mechanically identical to the 1110-101K, with the same inductance, current rating, DC resistance, and physical dimensions. The primary difference is product status (active vs. obsolete) and RoHS3 compliance.

Q: Are the Vishay Dale IHB1BV101K and IHB1EB101K suitable substitutes?

A: Yes, both Vishay Dale parts are suitable substitutes. They match all critical electrical parameters including inductance, tolerance, DC resistance, and operating temperature range. The current rating is 2.7 A compared to 2.8 A on the original part, which is acceptable for designs rated at 2.8 A.

Q: What is the difference between the IHB1BV101K and IHB1EB101K?

A: Both parts are electrically and mechanically identical. They share the same inductance, current rating, DC resistance, and physical dimensions. Selection between them depends on availability and supplier preference.

Q: Does packaging affect substitution compatibility?

A: The 1110-101K-RC is supplied in bulk packaging, while the original 1110-101K packaging is not specified. The Vishay Dale parts' packaging is also not specified. Packaging differences do not affect electrical or mechanical compatibility; they only affect procurement and handling procedures.

Q: Are there any compliance differences between these parts?

A: The 1110-101K-RC is RoHS3 compliant, while the original 1110-101K is RoHS non-compliant. For new designs or applications subject to RoHS regulations, the 1110-101K-RC is the appropriate choice. RoHS compliance status for the Vishay Dale alternatives is not specified in the available data.
