Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAA.M0.9GL.AC52GZ are identified based on strict equivalence of the following critical parameters:

• Connector type (Plug, Male Pins)
• Number of positions (9)
• Termination method (Solder Cup)
• Shell material (Polysulfone)
• Contact finish (Gold)
• Mounting type (Free Hanging, In-Line)
• Cable opening range (0.157" ~ 0.205")
• Ingress protection rating (IP50)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The ODU S21MA7-P09MCC0-527S meets these core substitution criteria. Variations in operating temperature range, current rating, and fastening mechanism details are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.9GL.AC52GZ and S21MA7-P09MCC0-527S are active production parts with equivalent core functionality for 9-position circular connector applications. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification.

The PAA.M0.9GL.AC52GZ provides a higher current rating of 3A and extended operating temperature range to 150°C. The S21MA7-P09MCC0-527S offers a current rating of 2.75A with operating temperature range to 120°C, and includes integrated strain relief in addition to the backshell.

Selection between these parts should be based on specific application requirements regarding current capacity and temperature extremes. Both connectors are suitable for industrial, medical, and testing equipment applications where solder cup termination and push-pull fastening are required.

Frequently Asked Questions (FAQ)

Q: What makes S21MA7-P09MCC0-527S a valid substitute for PAA.M0.9GL.AC52GZ?

A: Both connectors share identical core specifications: 9-position plug configuration with male pins, solder cup termination, polysulfone shell material, gold contact finish, IP50 ingress protection, and identical cable opening dimensions. Both are ROHS3 compliant and REACH unaffected.

Q: Are there differences in mechanical compatibility?

A: The shell size designation differs (M09 versus 1), but both connectors maintain the same cable opening range of 0.157" ~ 0.205" (4.00mm ~ 5.20mm). The S21MA7-P09MCC0-527S includes strain relief as an additional feature. Fastening mechanisms are both push-pull type, though the LEMO part specifies detent lock while the ODU part specifies push-pull only.

Q: What are the electrical differences?

A: The PAA.M0.9GL.AC52GZ is rated for 3A current, while the S21MA7-P09MCC0-527S is rated for 2.75A. The LEMO part operates to 150°C maximum, while the ODU part operates to 120°C maximum. Applications requiring the full 3A capacity or temperatures above 120°C should use the PAA.M0.9GL.AC52GZ.

Q: Are both parts suitable for medical applications?

A: Yes. Both connectors are listed for medical applications and maintain equivalent compliance certifications required for medical device integration.

Q: What is the difference in packaging?

A: The PAA.M0.9GL.AC52GZ is supplied in standard packaging, while the S21MA7-P09MCC0-527S is supplied in bulk packaging. Both are available as new original stock.
