Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM247080 is determined by strict equivalence across the following critical parameters:

• 24 positions per level configuration
• 5.00mm pitch spacing
• Vertical with board mating orientation
• 8 A current rating
• 250 V voltage rating
• 12-28 AWG wire gauge compatibility
• Through-hole mounting
• Screwless push-in spring termination
• Thermoplastic housing construction

The substitute part HM2470800000G manufactured by Amphenol Anytek meets all specified electrical and mechanical parameters, with the distinction 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 HM2470800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM247080. Both components maintain identical electrical specifications (8 A at 250 V), mechanical configuration (24 positions at 5.00mm 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The primary distinction is product lifecycle status: the OSTHM247080 is obsolete, while the HM2470800000G maintains active manufacturing status. The substitute part offers an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), providing additional thermal margin for demanding applications. The tin-plated brass contact material on the HM2470800000G provides enhanced corrosion resistance compared to unplated brass.

Frequently Asked Questions (FAQ)

Q: Can HM2470800000G be used as a direct replacement for OSTHM247080 in existing designs?

A: Yes. Both components share identical electrical ratings (8 A, 250 V), mechanical configuration (24 positions, 5.00mm pitch), mounting type (through-hole), and termination method (screwless push-in spring). PCB footprints and wire gauge compatibility (12-28 AWG) are equivalent.

Q: What is the difference in operating temperature ranges?

A: The OSTHM247080 operates from -30°C to 105°C, while the HM2470800000G operates from -40°C to 115°C. The substitute part provides 10°C additional margin at both temperature extremes.

Q: Are there differences in contact material specifications?

A: The OSTHM247080 uses brass contacts, while the HM2470800000G uses tin-plated brass contacts. Tin plating provides enhanced corrosion resistance and is suitable for all applications where the original brass contacts were specified.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the OSTHM247080 and HM2470800000G are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the significance of the product status difference?

A: The OSTHM247080 is classified as obsolete, indicating discontinued manufacturing. The HM2470800000G maintains active product status with ongoing availability and manufacturing support from Amphenol Anytek.
