OSTHB133180 Equivalent & Substitute Parts

Part Overview

The OSTHB133180 is a 13-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 classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this connector type is specified.

Engineering Selection Recommendations

The HB1331800000G is the direct equivalent for OSTHB133180 applications. Both parts meet identical electrical and mechanical specifications for 13-position, 3.81mm pitch terminal block applications. The substitute part offers the following advantages:

Active Production Status: HB1331800000G is currently manufactured, ensuring long-term availability and supply chain reliability
Enhanced Temperature Range: Operating range of -40°C ~ 115°C exceeds the original -30°C ~ 105°C specification, providing broader environmental compatibility
Improved Contact Plating: Tin-plated brass contacts on the substitute part offer enhanced corrosion resistance compared to unplated brass
Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status

For new designs or system replacements, the HB1331800000G is the recommended selection due to active production status and superior environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can HB1331800000G be used as a direct replacement for OSTHB133180 in existing PCB designs?

A: Yes. Both parts share identical pitch (0.150"), position count (13), mounting type (through-hole), and termination method (screwless push-button clamp). PCB footprints are compatible without modification.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active production) and operating temperature range. The HB1331800000G operates from -40°C to 115°C compared to -30°C to 105°C for the OSTHB133180. The substitute also features tin-plated brass contacts versus unplated brass.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 10 A at 300 V and accept wire gauges from 16-20 AWG. Voltage and current handling capacity are equivalent.

Q: Does the tin plating on HB1331800000G contacts affect compatibility?

A: No. Tin plating is a surface enhancement that improves corrosion resistance and contact reliability. It does not affect electrical or mechanical compatibility with the original part specification.

Q: What is the packaging difference?

A: OSTHB133180 packaging is not specified in available data. HB1331800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHB133180 and HB1331800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
