Engineering Selection Recommendations

Both the PAA.M1.0GL.AC52GZ and S21MA7-P10MCC0-527S are active production parts with ROHS3 compliance and EAR99 classification, making them suitable for equivalent selection in circular connector applications.

The PAA.M1.0GL.AC52GZ provides a current rating of 3A and operating temperature range of -50°C to 150°C. The S21MA7-P10MCC0-527S offers a current rating of 2.75A with an operating temperature range of -50°C to 120°C. Selection between these parts should be based on specific application requirements regarding current capacity and maximum operating temperature thresholds.

Both connectors feature identical cable opening specifications (0.157" ~ 0.205" / 4.00mm ~ 5.20mm), equivalent shell materials (Polysulfone PSU), and matching ingress protection ratings (IP50). The fastening mechanisms are both push-pull systems, with the LEMO part including detent lock functionality as an additional feature.

Frequently Asked Questions (FAQ)

Q: Can the S21MA7-P10MCC0-527S directly replace the PAA.M1.0GL.AC52GZ?

A: Yes, for applications where the operating temperature does not exceed 120°C and the current requirement does not exceed 2.75A. Both connectors share equivalent mechanical interfaces, termination methods, and ingress protection ratings.

Q: What is the difference in current rating between these two parts?

A: The PAA.M1.0GL.AC52GZ is rated for 3A, while the S21MA7-P10MCC0-527S is rated for 2.75A. Applications requiring the full 3A capacity must use the LEMO part.

Q: Are the operating temperature ranges compatible?

A: The PAA.M1.0GL.AC52GZ operates from -50°C to 150°C, while the S21MA7-P10MCC0-527S operates from -50°C to 120°C. Applications requiring operation above 120°C require the LEMO part.

Q: Do both connectors use the same cable opening specifications?

A: Yes. Both parts accept cable diameters in the range of 0.157" to 0.205" (4.00mm to 5.20mm), ensuring mechanical compatibility in cable assembly applications.

Q: What is the difference between the fastening mechanisms?

A: The PAA.M1.0GL.AC52GZ features push-pull fastening with detent lock, while the S21MA7-P10MCC0-527S uses push-pull fastening without the detent lock feature. Both provide secure connection interfaces.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the PAA.M1.0GL.AC52GZ and S21MA7-P10MCC0-527S are ROHS3 compliant and classified as EAR99, meeting current regulatory requirements for electronic component distribution and use.

Q: What packaging options are available?

A: The PAA.M1.0GL.AC52GZ is available in standard packaging, while the S21MA7-P10MCC0-527S is supplied in bulk packaging. Both have active inventory status with 1151 and 1050 units respectively in stock.
