MD-80 Circular Connector Plug - Equivalent & Substitute Parts

Part Overview

The MD-80 is an 8-position circular connector plug with male pins, manufactured by CUI Devices. It features solder termination with crimp pin adapter availability, push-pull fastening, and keyed orientation. The connector is designed for free-hanging inline mounting applications requiring robust electrical connections in the -20°C to 105°C operating range. This part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, application-specific requirements, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The MDP-008 (Adam Tech) qualifies as a substitute for the MD-80 based on the following critical parameters:

Both parts share identical specifications for:

• 8-position circular connector configuration
• Mini DIN shell size and insert
• Male pin connector type with keyed orientation
• Push-pull fastening mechanism
• Free-hanging inline mounting
• Solder termination capability
• ABS shell material
• Silver contact finish
• Brass contact material
• Polyamide (PA6) Nylon 6 insert material
• 100VAC and 12VDC voltage ratings
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity rating

Substitution is valid when these core electrical and mechanical parameters align with application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MD-80 and MDP-008 are Active status products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. Selection between these parts should be based on the following provided specifications:

The MD-80 supports dual current ratings (1A and 2A) with an extended operating temperature range of -20°C to 105°C. The MDP-008 is rated for 1A current operation within a -25°C to 70°C temperature range. Applications requiring the full 2A current capacity or extended high-temperature operation above 70°C must use the MD-80. The MDP-008 includes shielding and tin shell finish, which may provide additional electromagnetic interference protection in specific applications. The MD-80 offers crimp pin adapter availability as an alternative termination option.

Frequently Asked Questions (FAQ)

Q: Can the MDP-008 replace the MD-80 in all applications?

A: The MDP-008 is electrically and mechanically compatible with the MD-80 for applications operating within the MDP-008 specifications: maximum 1A current, -25°C to 70°C temperature range, and solder termination only. Applications requiring 2A current capacity or operation above 70°C require the MD-80.

Q: What are the key differences between these connectors?

A: The MD-80 provides higher current rating (1A, 2A versus 1A only) and extended operating temperature range (-20°C to 105°C versus -25°C to 70°C). The MDP-008 includes shielding and tin shell finish. Both share identical 8-position Mini DIN configuration, push-pull fastening, keyed orientation, and solder termination.

Q: Are both parts ROHS3 compliant?

A: Yes, both the MD-80 and MDP-008 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What packaging formats are available?

A: The MD-80 is supplied in Bag packaging. The MDP-008 is supplied in Tray packaging. Packaging format should be confirmed with procurement requirements.

Q: Can crimp pin termination be used with the MDP-008?

A: The MDP-008 supports solder termination only. Crimp pin adapter availability is specific to the MD-80. Applications requiring crimp pin termination must use the MD-80.
