OSTHB103180 Equivalent & Substitute Parts

Part Overview

The OSTHB103180 is a 10-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 10A at 300V, accommodating wire gauges from 16-20 AWG.

The OSTHB103180 carries an Obsolete product status. Identifying equivalent substitute parts is essential for ongoing system maintenance, design updates, and procurement continuity when original stock becomes unavailable.

Substitute Part Grouping Explanation

Substitution of the OSTHB103180 is determined by strict equivalence across the following critical parameters:

Position count: 10 positions per level
Pitch spacing: 0.150" (3.81mm)
Mating orientation: Horizontal with board configuration
Current and voltage ratings: 10A / 300V minimum
Wire gauge compatibility: 16-20 AWG
Termination method: Screwless push-button clamp
Mounting configuration: Through-hole PCB mounting
Interlocking feature: Side interlocking design

The substitute part HB1031800000G meets all these criteria and maintains full electrical and mechanical compatibility with the original OSTHB103180 specification.

Engineering Selection Recommendations

The HB1031800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHB103180. Both components maintain identical electrical specifications (10A, 300V), mechanical configuration (10-position, 3.81mm pitch, through-hole mounting), and termination methodology (screwless push-button clamp).

The substitute part offers advantages in product lifecycle status: HB1031800000G maintains Active product status with current manufacturing support, whereas OSTHB103180 is classified as Obsolete. Both components satisfy ROHS3 and REACH compliance requirements.

The HB1031800000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C) and tin-plated brass contacts, which may offer enhanced corrosion resistance in certain environmental applications. These characteristics represent functional improvements over the original specification.

Frequently Asked Questions (FAQ)

Q: Can HB1031800000G be used as a direct replacement for OSTHB103180 in existing designs?

A: Yes. Both components share identical pitch spacing (3.81mm), position count (10), mounting type (through-hole), and electrical ratings (10A, 300V). The footprint and electrical interface are fully compatible.

Q: What is the primary reason for substitution?

A: The OSTHB103180 is classified as Obsolete. The HB1031800000G maintains Active product status with ongoing manufacturing availability, ensuring long-term supply chain reliability.

Q: Are there differences in wire gauge compatibility?

A: No. Both components accept 16-20 AWG wire gauges without modification.

Q: How do the operating temperature ranges compare?

A: The HB1031800000G operates across -40°C ~ 115°C, which encompasses and exceeds the OSTHB103180 range of -30°C ~ 105°C. This provides broader environmental compatibility.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both OSTHB103180 and HB1031800000G are ROHS3 Compliant and REACH Unaffected.

Q: What is the difference in contact plating?

A: OSTHB103180 uses brass contacts, while HB1031800000G uses tin-plated brass contacts. Tin plating provides enhanced corrosion resistance in humid or corrosive environments.

Q: Is packaging different between these components?

A: The OSTHB103180 packaging specification is not provided. The HB1031800000G is supplied in Bulk packaging.
