Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHR095080 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (10 A), voltage rating (300 V), and wire gauge acceptance (12-28 AWG) must be identical or exceed the original specification
• Physical Compatibility: Number of positions (3), pitch spacing (0.300"/7.62mm), and through-hole mounting type must match exactly
• Termination Method: Wire termination must support screwless push-in spring connection
• Environmental Compliance: RoHS3 compliance and MSL rating must be maintained
• Mechanical Interface: Thermoplastic housing and angled mating orientation ensure PCB layout compatibility

The substitute part HR0950800000G manufactured by Amphenol Anytek meets all these criteria while offering active product status and extended operating temperature range.

Engineering Selection Recommendations

The HR0950800000G from Amphenol Anytek is the direct substitute for the obsolete OSTHR095080. Selection is based on the following engineering factors:

• Product Status: The substitute maintains active manufacturing status, ensuring long-term supply chain availability and design continuity
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying environmental and handling requirements
• Electrical & Mechanical Equivalence: All critical parameters including current, voltage, wire gauge, pitch, and termination method are identical
• Enhanced Performance: The substitute offers an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts, providing improved reliability in demanding environments
• PCB Layout Compatibility: The 45° angled orientation of the substitute is functionally equivalent to the original angled design, maintaining existing PCB mounting hole patterns and clearances

Frequently Asked Questions (FAQ)

Q: Can HR0950800000G be used as a direct drop-in replacement for OSTHR095080?

A: Yes. Both parts share identical electrical ratings (10A/300V), wire gauge acceptance (12-28 AWG), pitch spacing (0.300"/7.62mm), position count (3), and screwless push-in termination method. PCB mounting hole patterns and clearances are compatible.

Q: What is the difference between the angled orientations?

A: The OSTHR095080 uses a general angled configuration, while the HR0950800000G specifies 45° (135°) angle with the board. Both orientations are angled terminal block designs suitable for the same PCB layout applications. Physical verification of mounting hole alignment is recommended for critical applications.

Q: Does the tin plating on the HR0950800000G substitute affect compatibility?

A: No. Tin plating on the brass contacts of the substitute enhances corrosion resistance and contact reliability without affecting electrical or mechanical compatibility. This is a performance improvement over the original part.

Q: Are there any temperature-related considerations when substituting?

A: The substitute operates across a wider temperature range (-40°C to 115°C) compared to the original (-30°C to 105°C). This provides additional margin for applications operating at temperature extremes. No derating is required for applications within the original temperature specification.

Q: What is the inventory status of these parts?

A: OSTHR095080 has 1122 pieces in stock (obsolete status). HR0950800000G has 1157 pieces in stock (active status). For new designs and ongoing production, HR0950800000G is the recommended selection due to active manufacturing status.

Q: Are both parts RoHS3 compliant?

A: Yes. Both OSTHR095080 and HR0950800000G are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level), meeting current environmental and regulatory requirements.
