OSTHM145080 Equivalent & Substitute Parts

Part Overview

The OSTHM145080 is a 14-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical PCB mounting with 0.200" (5.08mm) pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. Substitute parts must maintain identical electrical performance, mechanical compatibility, and board-level integration characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM145080 is determined by strict equivalence across the following critical parameters:

• 14-position configuration with single-level design
• 0.200" (5.08mm) pitch spacing for PCB hole alignment
• Vertical with board mating orientation for top-entry wire connection
• 8 A current and 250 V voltage ratings for electrical load compatibility
• 12-28 AWG wire gauge acceptance for termination flexibility
• Through-hole mounting for permanent PCB integration
• Screwless push-in spring termination mechanism
• Side interlocking feature for mechanical stability
• Gray thermoplastic housing for environmental protection
• ROHS3 compliance for regulatory alignment

The substitute part HM1450800000G (Amphenol Anytek) satisfies all mandatory equivalence criteria and is classified as active product status, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The HM1450800000G from Amphenol Anytek is the direct functional equivalent for OSTHM145080 applications. Selection rationale is based on:

• Full electrical and mechanical parameter equivalence across all critical specifications
• Active product status ensuring sustained manufacturing and supply chain availability
• ROHS3 compliance matching the original component's regulatory standing
• Enhanced operating temperature range (-40°C ~ 115°C) providing superior thermal margin compared to the original (-30°C ~ 105°C)
• Tin-plated brass contacts offering improved corrosion resistance relative to unplated brass
• Identical through-hole footprint and push-in termination mechanism for direct PCB integration without layout modification

Frequently Asked Questions (FAQ)

Q: Can HM1450800000G be used as a direct replacement for OSTHM145080 without PCB redesign?

A: Yes. Both components share identical pitch spacing (0.200" / 5.08mm), through-hole mounting configuration, and 14-position layout. No PCB footprint modification is required.

Q: What is the significance of the tin plating on the HM1450800000G contacts?

A: Tin plating on brass contacts enhances corrosion resistance and improves long-term contact reliability in humid or corrosive environments. This is a material enhancement that does not affect electrical performance or mechanical compatibility.

Q: Does the extended operating temperature range of HM1450800000G affect compatibility?

A: No. The substitute's wider temperature range (-40°C ~ 115°C versus -30°C ~ 105°C) is a performance enhancement that maintains full backward compatibility with applications designed for the original component's specifications.

Q: Are there packaging differences between these parts?

A: The original OSTHM145080 packaging is not specified in available data. The HM1450800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level). Both are classified under ECCN EAR99 and HTSUS code 8536.90.4000.
