OSTHB033180 Equivalent & Substitute Parts

Part Overview

The OSTHB033180 is a 3-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 0.150" (3.81mm) pitch spacing. This component features screwless push-button clamp termination and is rated for 10 A at 300 V, accommodating wire gauges from 16-20 AWG. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHB033180 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: Substitute must provide exactly 3 positions at 0.150" (3.81mm) spacing to ensure PCB footprint compatibility
• Electrical Ratings: Minimum 10 A current and 300 V voltage ratings required; higher ratings are acceptable
• Termination Method: Screwless push-button clamp termination is mandatory for mechanical and operational compatibility
• Mounting Configuration: Through-hole horizontal orientation with board is non-negotiable for assembly compatibility
• Wire Gauge Compatibility: Must accept 16-20 AWG conductors
• Interlocking Feature: Side interlocking mechanism must be present for mechanical stability

The substitute part HB0331800000G by Amphenol Anytek meets all these criteria while offering improved product status (Active vs. Obsolete) and enhanced operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HB0331800000G from Amphenol Anytek is a direct functional equivalent to the OSTHB033180. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part offers the advantage of active product status, ensuring continued availability and manufacturer support. The extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts provide enhanced environmental tolerance and corrosion resistance. All electrical and mechanical parameters are identical, confirming PCB footprint and assembly compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Will the HB0331800000G fit the same PCB footprint as the OSTHB033180?

A: Yes. Both components share identical pitch (0.150"), position count (3), mounting type (through-hole), and mating orientation (horizontal with board). No PCB layout changes are required.

Q: Are the electrical ratings compatible?

A: Yes. Both parts are rated for 10 A at 300 V and accept 16-20 AWG wire. The substitute meets or exceeds all electrical specifications.

Q: What is the difference in contact plating?

A: The OSTHB033180 uses brass contacts, while the HB0331800000G uses tin-plated brass. Tin plating provides improved corrosion resistance and is standard in modern terminal block designs.

Q: Does the substitute support the same termination method?

A: Yes. Both components use screwless push-button clamp termination with side interlocking, ensuring identical assembly and operation procedures.

Q: Why is product status important for this substitution?

A: The OSTHB033180 is obsolete, meaning On Shore Technology Inc. no longer manufactures or supports it. The HB0331800000G is active, guaranteeing continued availability, technical support, and consistent manufacturing standards.

Q: Are there any compliance differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for current applications.

Q: Can the substitute handle wider temperature ranges?

A: Yes. The HB0331800000G operates from -40°C to 115°C, compared to the original part's -30°C to 105°C range, providing additional thermal margin for demanding environments.
