OSTHM054080 Equivalent & Substitute Parts

Part Overview

The OSTHM054080 is a 5-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical PCB mounting with 0.300" (7.62mm) pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The terminal block accommodates wire gauges from 12-28 AWG with push-in spring termination and supports applications requiring 8 A current capacity at 250 V.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM054080 is based on strict equivalence across the following critical parameters:

• Electrical Compatibility: Positions per level (5), pitch spacing (0.300"/7.62mm), current rating (8 A minimum), voltage rating (250 V minimum), and wire gauge acceptance (12-28 AWG)
• Mechanical Compatibility: Vertical with board mating orientation, through-hole mounting, push-in spring termination method, and thermoplastic housing
• Environmental Compliance: RoHS3 compliance and MSL rating of 1 (Unlimited)

The substitute part HM0540800000G meets all these criteria while offering enhanced specifications in voltage rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HM0540800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM054080. Both components maintain identical mechanical and electrical specifications for the critical parameters governing substitution: 5-position configuration, 7.62mm pitch, 8 A current capacity, 12-28 AWG wire gauge compatibility, and push-in spring termination.

The HM0540800000G offers enhanced performance margins with a 300 V voltage rating versus the original 250 V specification, and an extended operating temperature range of -40°C to 115°C compared to -30°C to 105°C. Both components carry ROHS3 compliance and unlimited MSL ratings, ensuring regulatory and environmental compatibility.

The HM0540800000G maintains active product status with current manufacturing availability, providing supply chain continuity for applications previously dependent on the obsolete OSTHM054080.

Frequently Asked Questions (FAQ)

Q: Can HM0540800000G be used as a direct replacement for OSTHM054080 in existing designs?

A: Yes. Both components share identical pitch spacing (7.62mm), position count (5), mating orientation (vertical with board), current rating (8 A), wire gauge range (12-28 AWG), and termination method (push-in spring). PCB footprints and mounting hole patterns are compatible.

Q: What are the key differences between these parts?

A: The HM0540800000G provides higher voltage rating (300 V vs. 250 V), extended operating temperature range (-40°C to 115°C vs. -30°C to 105°C), and tin-plated brass contacts versus unplated brass. The HM0540800000G maintains active product status while OSTHM054080 is obsolete.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM054080 and HM0540800000G are ROHS3 compliant and carry REACH Unaffected status.

Q: What is the packaging difference?

A: OSTHM054080 packaging information is not specified in available data. HM0540800000G is supplied in bulk packaging.

Q: Does the tin plating on HM0540800000G contacts affect compatibility?

A: No. Tin plating on brass contacts is a standard enhancement that improves corrosion resistance and contact reliability without affecting mechanical or electrical compatibility with the original design.
