OSTHB111180 Equivalent & Substitute Parts

Part Overview

The OSTHB111180 is an 11-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 0.394" (10.00mm) pitch spacing. This component features screwless push-button clamp termination and supports wire gauges from 14-20 AWG at 10A/300V ratings. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHB111180 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Positions per level (11), pitch (10.00mm), current rating (10A), and voltage rating (300V) must match exactly
Mechanical Compatibility: Mating orientation (horizontal with board), mounting type (through hole), and wire gauge support (14-20 AWG) must be identical
Termination Method: Wire termination type (screwless push-button clamp) and interlocking features must be preserved
Environmental Compliance: RoHS3 compliance and REACH unaffected status must be maintained

The substitute part HB1111800000G by Amphenol Anytek meets all these criteria while offering improved product status (active vs. obsolete) and enhanced operating temperature range.

Engineering Selection Recommendations

The HB1111800000G from Amphenol Anytek is a direct functional equivalent to the OSTHB111180. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part offers the advantage of active product status, providing improved long-term availability and supply chain stability compared to the obsolete original part. The tin-plated brass contact material in the substitute provides enhanced corrosion resistance while maintaining electrical performance within the specified parameters. The extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) provides additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can HB1111800000G be used as a direct replacement for OSTHB111180 in existing designs?

A: Yes. Both components share identical electrical ratings (10A/300V), mechanical configuration (11 positions at 10.00mm pitch), mounting method (through hole), and termination technology (screwless push-button clamp). PCB footprints and wire gauge compatibility are equivalent.

Q: What is the difference in contact plating between the two parts?

A: The OSTHB111180 uses brass contacts, while the HB1111800000G uses tin-plated brass. Tin plating provides enhanced corrosion resistance and improved contact reliability over extended service life, particularly in humid or corrosive environments.

Q: Does the extended temperature range of HB1111800000G affect compatibility?

A: No. The substitute part's operating range (-40°C to 115°C) encompasses the original part's range (-30°C to 105°C). This represents an enhancement with no compatibility concerns for applications within the original temperature specifications.

Q: Are there packaging differences between these parts?

A: The OSTHB111180 packaging information is not specified in available data. The HB1111800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement department for order fulfillment.

Q: What is the significance of the product status difference?

A: The OSTHB111180 is obsolete, indicating discontinued manufacturing and limited future availability. The HB1111800000G maintains active status, ensuring ongoing production, supply chain support, and technical documentation availability for the foreseeable future.
