Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAB.M0.5GL.AC39Z are identified based on strict alignment with the following critical parameters:

• Connector Type & Gender: Plug with male pins
• Position Count: 5 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 dust protection
• Insert Material: Polyetheretherketone (PEEK)
• Environmental Compliance: ROHS3 compliant, REACH unaffected

The substitute part S21MC7-P05MJG0-397S (ODU MEDI-SNAP®) meets these core substitution criteria. Variations in shell size designation (M05 vs. 1), fastening mechanism detail (push-pull with detent lock vs. push-pull), current rating (7A vs. 10A), and maximum operating temperature (150°C vs. 120°C) are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the PAB.M0.5GL.AC39Z and S21MC7-P05MJG0-397S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

The PAB.M0.5GL.AC39Z operates across a wider temperature range (-50°C to 150°C) compared to the ODU substitute (-50°C to 120°C). Applications requiring operation above 120°C should retain the LEMO part.

The ODU substitute provides a higher current rating (10A vs. 7A) and includes integrated strain relief in addition to the backshell, offering enhanced mechanical protection during cable flexing and installation.

Both connectors share identical cable opening specifications, shell material composition, contact finish, and ingress protection rating, supporting direct mechanical and electrical interchange in most applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the S21MC7-P05MJG0-397S replace the PAB.M0.5GL.AC39Z in all applications?

A: The ODU substitute is mechanically and electrically compatible for applications operating within -50°C to 120°C. Applications requiring operation above 120°C must use the LEMO part. Both connectors support identical solder cup termination, 5-position configuration, and IP50 ingress protection.

Q: What is the significance of the shell size designation difference (M05 vs. 1)?

A: Both designations refer to equivalent shell sizes within their respective manufacturer specifications. The cable opening range (0.106" ~ 0.154" / 2.70mm ~ 3.90mm) is identical for both parts, confirming mechanical compatibility.

Q: Does the higher current rating of the ODU part affect compatibility?

A: No. The 10A rating of the S21MC7-P05MJG0-397S exceeds the 7A requirement of the LEMO part. A higher current rating does not create incompatibility; it provides additional margin for applications with variable load conditions.

Q: Are there differences in fastening mechanisms between these parts?

A: The PAB.M0.5GL.AC39Z features push-pull with detent lock, while the S21MC7-P05MJG0-397S uses push-pull fastening. Both mechanisms provide secure mating and demating. The detent lock on the LEMO part provides additional mechanical retention.

Q: What packaging considerations apply to these parts?

A: The PAB.M0.5GL.AC39Z is supplied in standard packaging with 692 units in stock. The S21MC7-P05MJG0-397S is supplied in bulk packaging with 1073 units available. Both parts carry MSL 1 (Unlimited) moisture sensitivity, requiring no special storage conditions.

Q: Are both parts suitable for medical device applications?

A: Yes. Both connectors are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status, supporting use in regulated medical device designs.
