OSTHR154080 Equivalent & Substitute Parts

Part Overview

The OSTHR154080 is a 5-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for angled PCB mounting with 0.400" (10.16mm) pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. The part accommodates wire gauges from 12-28 AWG with a rated current capacity of 10 A at 300 V, utilizing screwless push-in spring termination for reliable wire retention in through-hole applications.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHR154080 is determined by strict equivalence across the following critical parameters:

Position Count & Pitch: 5 positions at 0.400" (10.16mm) spacing (PCB footprint compatibility)
Electrical Ratings: 10 A current and 300 V voltage minimum
Wire Gauge Compatibility: 12-28 AWG acceptance range
Termination Method: Screwless push-in spring mechanism
Mounting Configuration: Through-hole PCB mounting
Compliance: ROHS3 and REACH compliance status

The substitute part HR1540800000G, manufactured by Amphenol Anytek, meets all critical substitution criteria. While the mating orientation differs (45° angle versus straight angled configuration), the electrical performance, wire termination method, pitch spacing, and position count remain functionally equivalent for circuit board integration.

Engineering Selection Recommendations

The HR1540800000G serves as a direct functional substitute for the obsolete OSTHR154080 based on electrical equivalence and termination compatibility. Both components maintain identical pitch spacing, position count, current/voltage ratings, and wire gauge acceptance, ensuring PCB footprint and circuit integration compatibility.

The HR1540800000G offers enhanced specifications in two areas: extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts, which provide improved corrosion resistance compared to unplated brass. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The primary design consideration is mating orientation: the OSTHR154080 features a straight angled configuration, while the HR1540800000G incorporates a 45° (135°) angle with the board. PCB layout verification is required to confirm mechanical clearance and wire routing compatibility with the substitute orientation before implementation.

Frequently Asked Questions (FAQ)

Q: Can HR1540800000G replace OSTHR154080 in existing designs?

A: HR1540800000G is electrically and functionally equivalent across all critical parameters: 5-position configuration, 10.16mm pitch, 10 A/300 V ratings, and push-in spring termination. PCB layout verification is necessary to confirm the 45° angle orientation accommodates existing mechanical constraints and wire routing paths.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated for 10 A current, 300 V voltage, and accept 12-28 AWG wire gauges. The HR1540800000G operating temperature range (-40°C to 115°C) exceeds the OSTHR154080 specification (-30°C to 105°C).

Q: What is the difference in mating orientation?

A: The OSTHR154080 uses a straight angled configuration, while the HR1540800000G features a 45° (135°) angle relative to the PCB. This affects physical mounting geometry and wire entry angle. Board layout must accommodate this orientation difference.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHR154080 and HR1540800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the contact material difference?

A: OSTHR154080 uses brass contacts; HR1540800000G uses tin-plated brass contacts. Tin plating provides enhanced corrosion resistance and is suitable for applications requiring extended environmental durability.

Q: Is the HR1540800000G currently available?

A: Yes. HR1540800000G is classified as active production status with documented inventory availability, whereas OSTHR154080 is obsolete and no longer manufactured.
