Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM245080 is determined by strict equivalence across the following critical parameters:

• 24 positions per level configuration
• 0.200" (5.08mm) pitch spacing
• Vertical with board mating orientation
• Through-hole PCB mounting
• 8 A current rating and 250 V voltage rating
• 12-28 AWG wire gauge accommodation
• Screwless push-in spring termination method
• Thermoplastic housing construction
• Brass contact material with appropriate plating

The substitute part HM2450800000G manufactured by Amphenol Anytek meets all these critical parameters, with the additional advantage of active product status and an extended operating temperature range of -40°C ~ 115°C compared to the original -30°C ~ 105°C specification.

Parameter Comparison

Engineering Selection Recommendations

The HM2450800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM245080. Both components maintain identical electrical specifications (8 A current, 250 V voltage), mechanical configuration (24 positions, 5.08mm pitch), and termination methodology (screwless push-in spring). Both parts satisfy ROHS3 compliance and REACH unaffected status requirements.

The primary distinction is product lifecycle status: the OSTHM245080 is obsolete, while the HM2450800000G maintains active production status. The substitute part additionally provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), which may offer improved performance margin in temperature-sensitive applications. The tin plating on the brass contacts of the HM2450800000G provides enhanced corrosion resistance compared to unplated brass.

Frequently Asked Questions (FAQ)

Q: Can HM2450800000G be used as a direct replacement for OSTHM245080 in existing designs?

A: Yes. Both components share identical pitch spacing (5.08mm), position count (24), mounting type (through-hole), current/voltage ratings (8 A / 250 V), and wire termination method (screwless push-in spring). PCB footprints and electrical performance are equivalent.

Q: What is the significance of the extended temperature range in HM2450800000G?

A: The HM2450800000G operates from -40°C to 115°C, compared to the OSTHM245080 range of -30°C to 105°C. This extended range provides additional operational margin for applications subject to extreme environmental conditions, though both parts meet standard industrial temperature requirements.

Q: Are there packaging differences between these parts?

A: The OSTHM245080 packaging specification is not provided in the available data. The HM2450800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the OSTHM245080 and HM2450800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the significance of tin plating on the HM2450800000G contacts?

A: The tin plating on brass contacts provides enhanced corrosion resistance and improved contact reliability in humid or corrosive environments compared to unplated brass, while maintaining electrical performance equivalent to the original part.
