OSTHB020180 Equivalent & Substitute Parts

Part Overview

The OSTHB020180 is a 2-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with side entry configuration. This component features a 5mm (0.197") pitch and screwless push-button clamp termination, supporting wire gauges from 14-20 AWG at 10A and 300V ratings. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for applications requiring equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

The ED4101/2-KD qualifies as a direct substitute for the OSTHB020180 based on the following critical parameters:

Electrical Compatibility: Both parts maintain identical current (10A) and voltage (300V) ratings, ensuring equivalent power handling capacity.
Mechanical Compatibility: Both feature 2 positions per level with 0.197" (5.00mm) pitch spacing, horizontal board mating orientation, and through-hole mounting configuration.
Termination Method: Both employ screwless push-button clamp wire termination supporting 14-20 AWG wire gauges.
Environmental Performance: Both operate across the same temperature range (-30°C ~ 105°C) and carry identical ROHS3 compliance and unlimited MSL ratings.
Functional Features: Both incorporate side interlocking design for secure connector positioning.

Variations in housing material (thermoplastic vs. polyamide/nylon) and contact plating (brass vs. copper) do not affect substitution eligibility within the specified electrical and mechanical parameter envelope.

Engineering Selection Recommendations

Both OSTHB020180 and ED4101/2-KD are active production components from On Shore Technology Inc. with identical regulatory compliance profiles (ROHS3 and REACH unaffected status). Selection between these parts should be based on:

Inventory Availability: ED4101/2-KD maintains higher stock levels (3542 pcs vs. 712 pcs), providing supply chain advantage for high-volume applications.
Material Specifications: OSTHB020180 uses thermoplastic housing with brass contacts; ED4101/2-KD uses polyamide/nylon housing with copper contacts. Both material combinations are suitable for the specified electrical and environmental parameters.
Design Continuity: Either part may be selected for new designs or as a replacement in existing applications without modification to PCB layout or electrical schematic, provided the specified pitch and mounting footprint are maintained.

Frequently Asked Questions (FAQ)

Q: Can ED4101/2-KD replace OSTHB020180 in existing PCB designs? A: Yes. Both parts share identical pitch (5mm), position count (2), mounting type (through-hole), and electrical ratings (10A/300V). PCB footprints are compatible without modification.

Q: Are there differences in wire termination between these parts? A: No. Both employ identical screwless push-button clamp termination supporting 14-20 AWG wire gauges with equivalent clamping force and reliability.

Q: Do material differences affect electrical performance? A: No. The housing material (thermoplastic vs. polyamide) and contact plating (brass vs. copper) variations do not alter the electrical performance within the specified 10A/300V operating envelope and -30°C to 105°C temperature range.

Q: Are both parts compliant with current regulatory requirements? A: Yes. Both OSTHB020180 and ED4101/2-KD carry ROHS3 compliance and REACH unaffected status, meeting current environmental and safety standards.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. ED4101/2-KD offers superior inventory availability. Selection may also consider material preferences (thermoplastic vs. polyamide housing) based on specific application requirements.
