Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM043080 is determined by strict equivalence across the following critical parameters:

• Positions per level: 4 (exact match required)
• Pitch spacing: 0.150" (3.81mm) (exact match required)
• Mating orientation: Vertical with Board (exact match required)
• Current rating: 8 A (minimum requirement)
• Voltage rating: 300 V (minimum requirement)
• Wire gauge acceptance: 14-28 AWG (exact match required)
• Mounting type: Through Hole (exact match required)
• Wire termination method: Screwless - Leg Spring, Push-In Spring (exact match required)

The HM0430800000G manufactured by Amphenol Anytek meets all substitution criteria and is classified as an active product, providing continuity for applications currently using the obsolete OSTHM043080.

Parameter Comparison

Engineering Selection Recommendations

The HM0430800000G is the direct equivalent for OSTHM043080 applications. Both components maintain identical electrical and mechanical specifications across all critical parameters. The HM0430800000G offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications. The extended operating temperature range of the HM0430800000G (-40°C ~ 115°C versus -30°C ~ 105°C) provides additional thermal margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can HM0430800000G be used as a direct replacement for OSTHM043080?

A: Yes. Both components share identical pitch spacing (0.150"), position count (4), current rating (8 A), voltage rating (300 V), wire gauge acceptance (14-28 AWG), mounting type (through hole), and wire termination method (screwless push-in spring). PCB footprints are mechanically and electrically compatible.

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

A: OSTHM043080 uses brass contacts, while HM0430800000G uses brass with tin plating. Tin plating provides enhanced corrosion resistance and improved contact reliability in industrial environments.

Q: Are there packaging differences between these parts?

A: OSTHM043080 is supplied in standard packaging, while HM0430800000G is supplied in bulk packaging. Both formats contain identical components suitable for production assembly.

Q: Does the extended temperature range of HM0430800000G affect compatibility?

A: No. The extended operating range (-40°C ~ 115°C) of HM0430800000G is a superset of the OSTHM043080 range (-30°C ~ 105°C). Applications within the original temperature specification remain fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM043080 and HM0430800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
