Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8080-1G45 is evaluated based on the following critical parameters that define functional compatibility:

Core Compatibility Criteria:

• Number of positions: 3-position configuration
• Transistor package type: TO-3 or TO-5 family
• Contact material: Beryllium copper for mating and post contacts
• Operating temperature range: -55°C to 125°C minimum
• Termination method: Solder termination
• Housing design: Closed frame configuration
• Moisture sensitivity: MSL 1 (Unlimited)

The substitute part 917-43-103-41-005000 (Mill-Max Manufacturing Corp.) satisfies these core criteria with the following considerations:

• Maintains 3-position configuration with round contact geometry
• Operates within identical temperature range (-55°C to 125°C)
• Utilizes beryllium copper mating contacts with gold finish (enhanced corrosion resistance compared to tin)
• Provides solder termination with brass alloy posts
• Maintains closed frame design and MSL 1 rating
• Transitions from chassis mount (TO-3) to through-hole mount (TO-5) configuration

The primary distinction is the shift from TO-3 chassis mount to TO-5 through-hole mount, which represents a mechanical interface change requiring board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 8080-1G45 is obsolete, while the substitute part 917-43-103-41-005000 maintains active product status with current manufacturing support and availability (1917 pieces in stock versus 881 pieces for the obsolete part).

Compliance and Certification: The substitute part 917-43-103-41-005000 is ROHS3 compliant and REACH unaffected, providing regulatory alignment for new designs and systems subject to environmental compliance requirements. The original 8080-1G45 is RoHS non-compliant, which may restrict its use in regulated applications.

Contact Finish Enhancement: The substitute part features gold-plated mating contacts (30.0µin thickness) compared to tin plating on the original part. Gold plating provides superior corrosion resistance and contact reliability in applications subject to environmental exposure or extended storage periods.

Mechanical Interface Transition: Selection of the 917-43-103-41-005000 requires modification from chassis mount to through-hole mounting. This transition necessitates PCB layout changes and mechanical redesign of the mounting structure. The through-hole configuration may provide improved mechanical stability in vibration-prone applications.

Temperature and Electrical Performance: Both parts operate across the identical -55°C to 125°C temperature range and maintain MSL 1 moisture sensitivity ratings, ensuring equivalent thermal and environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 917-43-103-41-005000 directly replace the 8080-1G45 without PCB modifications?

A: No. The 8080-1G45 is a chassis mount connector, while the 917-43-103-41-005000 is a through-hole mount connector. Direct substitution requires PCB layout modification to accommodate the through-hole mounting configuration. The contact geometry also differs (oval versus round positions).

Q: What is the significance of the contact finish difference between tin and gold?

A: The 8080-1G45 uses tin-plated contacts, while the 917-43-103-41-005000 uses gold-plated mating contacts. Gold provides superior corrosion resistance, lower contact resistance, and improved reliability in applications with extended storage, high humidity, or corrosive environments. Tin plating is adequate for standard applications but offers less long-term contact stability.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 8080-1G45 and 917-43-103-41-005000 operate across -55°C to 125°C, ensuring equivalent thermal performance for applications within this range.

Q: What is the impact of the housing material difference?

A: The 8080-1G45 uses PTFE (Polytetrafluoroethylene) housing, while the 917-43-103-41-005000 uses PCT/Polyester housing. Both materials provide adequate electrical insulation and thermal stability across the operating temperature range. PTFE offers superior chemical resistance, while PCT/Polyester provides enhanced mechanical strength and dimensional stability.

Q: Does the RoHS compliance difference affect substitution decisions?

A: The 917-43-103-41-005000 is ROHS3 compliant, while the 8080-1G45 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the substitute part is the appropriate selection. For legacy systems without compliance requirements, either part may be acceptable based on availability and performance criteria.

Q: What is the significance of the current rating specification on the substitute part?

A: The 917-43-103-41-005000 specifies a 3 A current rating, while the 8080-1G45 does not provide this specification. The 3 A rating on the substitute part indicates the maximum continuous current the connector contacts can safely carry. Applications requiring current handling above this threshold require verification against the original part's undocumented specifications or consultation with the manufacturer.

Q: Are both parts suitable for high-reliability applications?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity ratings and closed frame designs, indicating suitability for standard reliability applications. The substitute part's active product status, ROHS3 compliance, and gold contact finish provide enhanced reliability characteristics for new designs. The original part's obsolete status may limit long-term support for high-reliability programs.
