PAB.M0.4GL.AC39Z Equivalent & Substitute Parts

Part Overview

The PAB.M0.4GL.AC39Z is a 4-position circular connector plug manufactured by LEMO, featuring male pins with solder cup termination and gold-plated mating contacts. This connector is designed for free-hanging, in-line applications requiring push-pull detent lock fastening. The product is active and in stock with 1095 units available. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling component interchangeability in applications where the original part may be unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAB.M0.4GL.AC39Z is determined by strict alignment of the following critical parameters:

• Connector type: Plug with male pins
• Position count: 4 positions
• Termination method: Solder cup
• Shell material: Polysulfone (PSU)
• Contact finish: Gold plating on mating surfaces
• Mounting configuration: Free hanging, in-line orientation
• Ingress protection: IP50 minimum
• Cable opening range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Regulatory compliance: ROHS3 compliant

The substitute part S21MC7-P04MJG0-397S meets these criteria. Variations in current rating, operating temperature range, fastening mechanism details, and orientation designation do not preclude substitution when the core electrical and mechanical interfaces remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the PAB.M0.4GL.AC39Z and S21MC7-P04MJG0-397S are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications. The LEMO part offers a higher maximum operating temperature of 150°C compared to the ODU substitute at 120°C. The ODU part provides a higher current rating of 10A versus 8A on the LEMO part. Selection between these parts should be based on application-specific thermal and current requirements within the stated operating parameters. Both parts are available in production quantities and maintain equivalent mechanical and electrical interfaces for solder cup termination in 4-position configurations.

Frequently Asked Questions (FAQ)

Q: Can the S21MC7-P04MJG0-397S replace the PAB.M0.4GL.AC39Z in all applications?

A: Substitution is valid when application requirements fall within the operating parameters of both parts. The ODU substitute supports applications requiring up to 10A current and operating temperatures up to 120°C. Applications requiring operation above 120°C must use the LEMO part, which is rated to 150°C.

Q: Are the shell sizes M04 and 1 mechanically equivalent?

A: Shell size designations differ between manufacturers. Mechanical compatibility is determined by the matching cable opening range (0.106" ~ 0.154" / 2.70mm ~ 3.90mm) and solder cup interface specifications, which are identical between both parts.

Q: What is the difference in fastening mechanisms between these parts?

A: The LEMO part specifies push-pull with detent lock fastening. The ODU part specifies push-pull fastening. Both employ push-pull engagement, with the detent lock feature providing additional mechanical retention in the LEMO design.

Q: Do both parts support the same applications?

A: Both parts are rated for industrial, medical, and testing equipment applications. The LEMO part additionally lists automotive applications. Application suitability depends on specific thermal and current requirements within each part's operating range.

Q: Are there packaging differences between these parts?

A: The LEMO part is supplied in standard packaging. The ODU substitute is supplied in bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance.
