BU060Z-178-HT Equivalent & Substitute Parts

Part Overview

The BU060Z-178-HT is a 6-position DIP socket with 0.3" (7.62mm) row spacing, manufactured by On Shore Technology Inc. This surface mount connector features gold-plated beryllium copper mating contacts and is designed for IC and transistor applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across electrical specifications, mechanical dimensions, and mounting characteristics.

Engineering Selection Recommendations

Primary Substitutes (ROHS3 Compliant, Active Status):

110-43-306-41-105000, 114-41-306-41-117000, 114-43-306-41-117000, 114-91-306-41-117000 are direct substitutes with active product status and ROHS3 compliance. These parts maintain all critical electrical and mechanical parameters. Current rating is increased to 3 A, providing enhanced capability over the original 1 A specification.

Alternative Substitute (ROHS3 Compliant, Matched Current Rating):

114-87-306-41-117101 (Preci-Dip) maintains the original 1 A current rating and ROHS3 compliance with active product status. This part is suitable for applications requiring current rating equivalence to the original BU060Z-178-HT.

Secondary Substitutes (RoHS Non-Compliant, Active Status):

110-93-306-41-105000 and 114-93-306-41-117000 are functionally equivalent but carry RoHS non-compliant status. These parts are suitable only for applications where RoHS compliance is not required.

Alternative Contact Finish (ROHS3 Compliant, Active Status):

214-99-306-01-670800 features tin-lead mating contact finish instead of gold. This part maintains all other critical parameters and is suitable for applications where contact finish material substitution is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the original BU060Z-178-HT?

A: Yes. The substitute parts with 3 A current rating (110-43-306-41-105000, 114-41-306-41-117000, 114-43-306-41-117000, 114-91-306-41-117000) are electrically and mechanically compatible. Higher current rating indicates enhanced capability and does not create incompatibility with the original application.

Q: What is the difference between open frame and closed frame sockets in this product category?

A: The BU060Z-178-HT features an open frame design. The substitute 214-99-306-01-670800 uses a closed frame design. Both maintain identical electrical and mechanical compatibility. Frame type selection depends on application-specific mechanical requirements and PCB layout considerations.

Q: Are there differences in contact finish thickness among the substitute parts?

A: Yes. Contact finish thickness varies across substitutes (ranging from 10.0µin to 78.7µin for mating contacts). These variations remain within acceptable engineering tolerances for DIP socket applications and do not affect functional compatibility.

Q: Which substitute part should I select for new designs requiring RoHS compliance?

A: Select from 110-43-306-41-105000, 114-41-306-41-117000, 114-43-306-41-117000, 114-87-306-41-117101, or 114-91-306-41-117000. All carry ROHS3 Compliant status and active product status.

Q: What is the significance of the 0.3" (7.62mm) row spacing specification?

A: Row spacing defines the distance between the two rows of contact positions in the DIP socket. The 0.3" specification is a standard dimension for 6-position DIP sockets and is maintained across all substitute parts, ensuring PCB footprint compatibility.

Q: Can I substitute the BU060Z-178-HT with 214-99-306-01-670800 if my application uses gold-plated contacts?

A: The 214-99-306-01-670800 features tin-lead mating contact finish instead of gold. Contact finish material substitution is an engineering decision dependent on application requirements. Electrical performance remains equivalent; however, contact material properties differ.

Q: Are all substitute parts available in the same packaging format as the original?

A: No. The original BU060Z-178-HT is supplied in bulk packaging. Substitute parts are available in tube or bulk packaging depending on the specific part number. Packaging format does not affect electrical or mechanical compatibility.
