PAG.M0.8GL.AC39Z Equivalent & Substitute Parts

Part Overview

The PAG.M0.8GL.AC39Z is an 8-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is designed for free-hanging inline applications requiring push-pull detent lock fastening. The part is currently active in production with 772 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component substitution within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PAG.M0.8GL.AC39Z is permissible with parts meeting the following criteria:

• 8-position circular connector configuration
• Male pin plug connector type
• Solder cup termination method
• Polysulfone (PSU) shell material
• Gold contact finish on mating surfaces
• IP50 ingress protection rating
• Free-hanging inline mounting
• Push-pull fastening mechanism
• Operating temperature range compatible with or exceeding -50°C to 150°C
• Current rating of 5A or greater
• Cable opening range of 0.106" to 0.154" (2.70mm to 3.90mm)
• ROHS3 compliance and REACH unaffected status

The substitute part S21M07-P08MFG0-397S from ODU meets these core substitution parameters with the exception of operating temperature range (maximum 120°C versus 150°C) and current rating (3.85A versus 5A), which represent functional limitations in specific high-temperature or high-current applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAG.M0.8GL.AC39Z and S21M07-P08MFG0-397S are active production parts with ROHS3 compliance and REACH unaffected status, suitable for industrial, medical, and testing equipment applications.

Selection between these parts is determined by application-specific requirements:

The PAG.M0.8GL.AC39Z is specified for applications requiring the full 5A current rating and operating temperatures up to 150°C. This part supports automotive applications in addition to industrial and medical use cases.

The S21M07-P08MFG0-397S is suitable for applications operating within the 3.85A current limit and maximum 120°C temperature range. This part includes integrated strain relief and is designated within the ODU MEDI-SNAP® series, positioning it for medical device applications with specific connector ecosystem requirements.

Both parts share identical mechanical interfaces, cable opening specifications, and contact finish characteristics, enabling physical interchangeability in applications where the electrical and thermal limitations of the substitute part are acceptable.

Frequently Asked Questions (FAQ)

Q: Can S21M07-P08MFG0-397S replace PAG.M0.8GL.AC39Z in all applications?

A: Physical and mechanical compatibility exists between these parts. Substitution is permissible only in applications where the circuit operates at or below 3.85A and the maximum operating temperature does not exceed 120°C. Applications requiring the full 5A rating or temperatures above 120°C must use the PAG.M0.8GL.AC39Z.

Q: What are the key differences between these connector models?

A: The primary differences are current rating (5A versus 3.85A), maximum operating temperature (150°C versus 120°C), and fastening mechanism detail (detent lock versus standard push-pull). Both connectors share 8-position configuration, solder cup termination, gold contact finish, IP50 protection, and identical cable opening specifications.

Q: Are both parts compliant with regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected. Both are active production parts suitable for industrial, medical, and testing equipment applications.

Q: What is the significance of the cable opening specification?

A: The cable opening range of 0.106" to 0.154" (2.70mm to 3.90mm) defines the acceptable cable diameter for proper backshell engagement. Both parts share this specification, ensuring compatible cable assembly practices.

Q: Does the ODU part include additional features?

A: The S21M07-P08MFG0-397S includes integrated strain relief in addition to the backshell feature present on both parts. This addition does not affect mechanical interchangeability but provides enhanced cable protection in the ODU design.
