Key Parameters

Substitute Part Grouping Explanation

The HM0990800000G from Amphenol Anytek qualifies as a direct substitute for the OSTHM099080 based on the following critical parameters:

• Electrical Compatibility: Identical current (8A) and voltage (250V) ratings
• Mechanical Compatibility: Matching 9-position configuration with 0.295" (7.50mm) pitch spacing
• Termination Method: Identical screwless push-in spring wire termination supporting 12-28 AWG wire gauges
• Mounting Configuration: Vertical with board through-hole mounting
• Housing & Contact Materials: Thermoplastic housing with brass-based contacts
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status

The substitute part demonstrates enhanced operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C) and improved contact plating specification (tin-plated brass), providing superior performance margins within the same electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

The HM0990800000G is the qualified substitute for OSTHM099080 applications. The substitute part maintains active product status with established supply chain availability, addressing the obsolescence of the original component. Both parts satisfy identical ROHS3 and REACH compliance requirements, ensuring regulatory continuity in applications subject to these standards.

The HM0990800000G provides extended operating temperature capability and enhanced contact plating specification without modification to PCB layout, connector footprint, or electrical interface requirements. Direct pin-for-pin and footprint compatibility is maintained across all critical dimensions and termination specifications.

Frequently Asked Questions (FAQ)

Q: Can HM0990800000G be used as a direct replacement for OSTHM099080 without PCB modification?

A: Yes. The substitute part maintains identical pitch spacing (7.50mm), through-hole mounting configuration, and electrical ratings. No PCB layout changes are required.

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

A: OSTHM099080 uses brass contacts, while HM0990800000G specifies brass with tin plating. Tin plating provides enhanced corrosion resistance and improved contact reliability without affecting electrical performance or compatibility.

Q: Are there temperature range limitations when substituting?

A: The HM0990800000G operates across -40°C to 115°C, exceeding the original part's -30°C to 105°C range. Applications within the original temperature specification remain fully compatible.

Q: Do both parts support the same wire gauge range?

A: Yes. Both OSTHM099080 and HM0990800000G accommodate 12-28 AWG wire gauges with identical screwless push-in spring termination.

Q: Are packaging considerations relevant for substitution?

A: OSTHM099080 is supplied in standard packaging, while HM0990800000G is available in bulk packaging. Packaging format does not affect component functionality or compatibility.

Q: What certifications apply to the substitute part?

A: HM0990800000G maintains ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original component.
