Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM195080 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 19 positions at 0.200" (5.08mm) spacing
• Electrical Ratings: 8A current and 250V voltage minimum
• Wire Gauge Compatibility: 12-28 AWG support
• Mounting Configuration: Through-hole vertical PCB orientation
• Termination Method: Screwless push-in spring mechanism
• Mechanical Features: Side interlocking design
• Housing & Contact Materials: Thermoplastic housing with brass contacts

The substitute part HM1950800000G (Amphenol Anytek) meets all these criteria with identical electrical and mechanical specifications, differing only in manufacturer, product status (active vs. obsolete), and minor enhancements to operating temperature range and contact plating.

Parameter Comparison

Engineering Selection Recommendations

The HM1950800000G from Amphenol Anytek is a direct functional equivalent to the OSTHM195080. Both components maintain identical electrical performance (8A/250V), mechanical configuration (19-position, 5.08mm pitch, through-hole vertical), and termination methodology (screwless push-in spring).

Selection of HM1950800000G is supported by:

• Active product status ensuring continued availability and supply chain stability
• ROHS3 compliance matching the original component
• REACH unaffected designation maintaining regulatory alignment
• Enhanced operating temperature range (-40°C to 115°C vs. -30°C to 105°C) providing broader environmental tolerance
• Tin-plated brass contacts offering improved corrosion resistance compared to unplated brass

The substitute part is suitable for direct replacement in applications currently using OSTHM195080, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can HM1950800000G be used as a direct replacement for OSTHM195080 without PCB redesign?

A: Yes. Both components share identical pitch (5.08mm), position count (19), mounting type (through-hole vertical), and footprint geometry. No PCB layout modifications are necessary.

Q: What is the significance of the tin plating on HM1950800000G contacts?

A: Tin plating on brass contacts provides enhanced corrosion resistance and improved contact reliability in humid or corrosive environments compared to unplated brass. This represents a material enhancement without affecting electrical performance.

Q: Does the extended operating temperature range of HM1950800000G affect compatibility?

A: No. The substitute's temperature range (-40°C to 115°C) encompasses the original specification (-30°C to 105°C). This provides additional margin for applications operating at temperature extremes.

Q: Are there packaging differences between OSTHM195080 and HM1950800000G?

A: OSTHM195080 packaging is not specified in available data. HM1950800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both components meet the same regulatory standards?

A: Yes. Both are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for EU and international markets.

Q: Why is OSTHM195080 classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation. HM1950800000G, as an active product from Amphenol Anytek, ensures continued component availability for new designs and legacy system maintenance.
