PAG.M0.8GL.AC65Z Equivalent & Substitute Parts

Part Overview

The PAG.M0.8GL.AC65Z is an 8-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is designed for applications requiring reliable circular connection interfaces in automotive, industrial, medical, and testing equipment environments. The part is currently active in production with 851 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAG.M0.8GL.AC65Z is determined by the following critical parameters:

• Connector Configuration: 8-position circular connector plug with male pins
• Termination Method: Solder cup termination
• Contact Finish: Gold plating on mating surfaces
• Shell Material: Polysulfone (PSU) construction
• Fastening Mechanism: Push-pull coupling with detent lock
• Ingress Protection: IP50 dust protection rating
• Cable Opening Diameter: 0.209" ~ 0.256" (5.30mm ~ 6.50mm)
• Regulatory Compliance: ROHS3 compliant

The substitute part S21M07-P08MFG0-657S from ODU meets these core electrical and mechanical requirements, enabling functional interchange in applications where the specified parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the PAG.M0.8GL.AC65Z and S21M07-P08MFG0-657S are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and medical applications. The primary differences between these parts are:

• Current Rating: The LEMO part supports 5A, while the ODU substitute supports 3.85A. Selection must account for circuit current requirements.
• Operating Temperature Range: The LEMO part operates to 150°C; the ODU part to 120°C. Applications requiring operation above 120°C require the LEMO part.
• Fastening Detail: The LEMO part specifies detent lock; the ODU part specifies push-pull only. Mechanical coupling requirements must be evaluated.

Both parts share identical mechanical interfaces (cable opening, shell size, pin count) and material specifications (PSU shell, PEEK insert, gold contact finish), supporting physical and electrical compatibility within the stated parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the ODU S21M07-P08MFG0-657S replace the LEMO PAG.M0.8GL.AC65Z in all applications?

A: Substitution is valid only when circuit current does not exceed 3.85A and operating temperature does not exceed 120°C. The LEMO part's higher current rating (5A) and extended temperature range (-50°C to 150°C) make it necessary for applications outside these ODU limits.

Q: Are the physical mating interfaces identical between these two connectors?

A: Yes. Both connectors share the same 8-position configuration, cable opening diameter (0.209" ~ 0.256"), shell material (PSU), and insert material (PEEK), ensuring mechanical compatibility.

Q: What is the difference in fastening mechanisms?

A: The LEMO part includes a detent lock feature in addition to push-pull coupling. The ODU part specifies push-pull only. Applications requiring positive mechanical locking should use the LEMO part.

Q: Are both parts suitable for medical applications?

A: Yes. Both parts list medical applications in their specifications and maintain ROHS3 compliance and REACH unaffected status.

Q: What is the significance of the gold contact finish?

A: Gold plating on mating surfaces provides corrosion resistance and ensures reliable electrical contact across the operating temperature range for both parts.
