Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM197080 is determined by strict equivalence across the following critical parameters:

• 19 positions per level configuration
• 0.197" (5.00mm) pitch spacing
• Vertical with board mating orientation
• Through-hole mounting technology
• 8 A current rating and 250 V voltage rating
• 12-28 AWG wire gauge acceptance
• Screwless push-in spring termination method
• Thermoplastic housing construction
• Brass contact material with plating

The substitute part HM1970800000G manufactured by Amphenol Anytek meets all these critical parameters, establishing direct functional equivalence for circuit design and PCB layout purposes.

Parameter Comparison

Engineering Selection Recommendations

The HM1970800000G from Amphenol Anytek provides direct functional substitution for the obsolete OSTHM197080. Both components maintain identical electrical specifications, mechanical dimensions, and termination methodology. The substitute part offers an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts, which provide enhanced corrosion resistance compared to the base brass plating of the original component.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The HM1970800000G maintains active product status with documented inventory availability, eliminating supply chain risk associated with the obsolete OSTHM197080.

Frequently Asked Questions (FAQ)

Q: Can HM1970800000G be used as a direct replacement for OSTHM197080 in existing PCB designs?

A: Yes. Both components share identical pitch spacing (5.00mm), position count (19), mounting type (through-hole), and electrical ratings (8 A, 250 V). PCB footprints and circuit connections require no modification.

Q: What is the difference between the brass plating specifications?

A: The OSTHM197080 uses standard brass contacts, while the HM1970800000G specifies brass with tin plating. Tin plating provides additional corrosion resistance and is compatible with identical circuit applications.

Q: Does the extended temperature range of HM1970800000G affect compatibility?

A: No. The extended range (-40°C to 115°C versus -30°C to 105°C) represents an enhancement that maintains full compatibility with applications designed for the original component's temperature specifications.

Q: Are both components RoHS compliant?

A: Yes. Both OSTHM197080 and HM1970800000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: What packaging format is available for HM1970800000G?

A: HM1970800000G is supplied in bulk packaging with 838 pieces currently in stock inventory.
