Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHB032180 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (10A), voltage rating (300V), and wire gauge compatibility (14-20 AWG) must match exactly
• Physical Configuration: 3 positions per level, 7.5mm pitch spacing, and horizontal board orientation must be identical
• Termination Method: Screwless push-button clamp wire termination is mandatory
• Mounting: Through-hole PCB mounting is required
• Compliance: RoHS3 compliance and REACH unaffected status must be maintained

The substitute part HB0321800000G manufactured by Amphenol Anytek meets all these criteria, with the additional benefit of active product status and extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The HB0321800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHB032180. Both components maintain identical electrical ratings, physical dimensions, and termination characteristics. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain stability. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The extended operating temperature range of the HB0321800000G (-40°C ~ 115°C) provides additional thermal margin compared to the original part, making it suitable for applications with broader environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can HB0321800000G be used as a direct replacement for OSTHB032180 in existing designs?

A: Yes. Both components share identical electrical specifications (10A, 300V), physical configuration (3 positions, 7.5mm pitch), mounting type (through-hole), and wire termination method (screwless push-button clamp). PCB layouts and wire gauge requirements remain unchanged.

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

A: The OSTHB032180 uses brass contacts, while the HB0321800000G uses brass with tin plating. Tin plating provides enhanced corrosion resistance and improved contact reliability, making it a compatible upgrade.

Q: Does the extended temperature range of HB0321800000G affect compatibility?

A: No. The extended operating range (-40°C ~ 115°C versus -30°C ~ 105°C) represents an improvement that does not compromise compatibility. Applications operating within the original temperature range will function identically.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHB032180 and HB0321800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging is available for the substitute part?

A: The HB0321800000G is supplied in bulk packaging, with 1022 pieces available in current inventory.
