Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHB042180 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (10A), voltage rating (300V), and wire gauge acceptance (14-20 AWG) must match exactly
• Mechanical Compatibility: Position count (4), pitch spacing (7.50mm), mating orientation (horizontal with board), and mounting type (through hole) must be identical
• Termination Method: Wire termination technology (screwless push-button clamp) must be equivalent
• Environmental Compliance: RoHS3 compliance and moisture sensitivity level (MSL 1) must be maintained

The substitute part HB0421800000G, manufactured by Amphenol Anytek, meets all these criteria while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HB0421800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHB042180. Both components maintain identical electrical ratings, mechanical dimensions, and termination characteristics. The substitute part offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity classification, meeting regulatory requirements for equivalent applications.

The HB0421800000G provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), which represents an operational enhancement without introducing compatibility concerns for designs originally specified for the OSTHB042180.

Frequently Asked Questions (FAQ)

Q: Can HB0421800000G be used as a direct replacement for OSTHB042180 in existing designs?

A: Yes. Both components share identical electrical ratings (10A, 300V), mechanical configuration (4 positions, 7.50mm pitch, horizontal orientation), and termination method (screwless push-button clamp). PCB footprints and mounting hole patterns are compatible.

Q: What is the difference in contact plating between these parts?

A: The OSTHB042180 uses brass contacts, while the HB0421800000G uses brass with tin plating. Tin plating provides enhanced corrosion resistance and is functionally compatible with the original specification.

Q: Does the extended temperature range of HB0421800000G affect compatibility?

A: No. The extended range (-40°C to 115°C) is a superset of the original specification (-30°C to 105°C). Designs qualified for the original part remain fully compatible.

Q: Are both parts RoHS3 compliant?

A: Yes. Both OSTHB042180 and HB0421800000G are ROHS3 compliant with MSL 1 moisture sensitivity classification.

Q: What wire gauges are supported?

A: Both parts accept wire gauges from 14-20 AWG with identical current handling capacity of 10A.
