Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M1.4GL.AC52Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug configuration with 14 male pins
• Termination Method: Solder cup termination required
• Shell Material & Finish: Polysulfone (PSU) shell with gold contact finish
• Mounting Configuration: Free hanging (in-line) orientation
• Ingress Protection: IP50 dust protection rating
• Fastening Mechanism: Push-pull connection system
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The substitute part S21MA7-P14MCC0-527S meets these core substitution criteria. Both parts share identical connector topology, termination approach, shell material composition, contact finish specification, mounting style, and ingress protection rating. Regulatory compliance status is equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both PAA.M1.4GL.AC52Z and S21MA7-P14MCC0-527S are active production parts with ROHS3 compliance and EAR99 classification. Selection between these parts should be based on the following factors:

PAA.M1.4GL.AC52Z (LEMO) is the primary specification. Use this part when the design requires the extended operating temperature range of -50°C to 150°C or when LEMO series compatibility is specified.

S21MA7-P14MCC0-527S (ODU) is a qualified substitute when:

• Operating temperature requirements do not exceed 120°C
• The higher current rating of 2.5A is acceptable or beneficial
• ODU MEDI-SNAP® series compatibility is acceptable
• Supply chain availability of the primary part is constrained

Both parts maintain identical mechanical interface, electrical termination method, shell construction, contact finish, and ingress protection specifications. Current inventory levels are 1015 units for the primary part and 952 units for the substitute.

Frequently Asked Questions (FAQ)

Q: Can S21MA7-P14MCC0-527S be used as a direct replacement for PAA.M1.4GL.AC52Z?

A: Yes, for applications where the operating temperature does not exceed 120°C. Both connectors share identical 14-position configuration, solder cup termination, polysulfone shell material, gold contact finish, IP50 ingress protection, and free-hanging mounting style. The substitute part has a higher current rating (2.5A vs 2A), which is compatible with the original specification.

Q: What is the key difference between these two parts?

A: The primary differences are operating temperature range (PAA.M1.4GL.AC52Z: -50°C to 150°C; S21MA7-P14MCC0-527S: -50°C to 120°C) and current rating (2A vs 2.5A). The substitute part includes strain relief features and belongs to the ODU MEDI-SNAP® series, while the primary part is from the LEMO 2P series.

Q: Are both parts RoHS compliant?

A: Yes, both PAA.M1.4GL.AC52Z and S21MA7-P14MCC0-527S are ROHS3 compliant and classified as EAR99 for export purposes.

Q: What cable opening sizes are compatible with these connectors?

A: Both connectors accept cable diameters in the range of 0.157" to 0.205" (4.00mm to 5.20mm).

Q: Can these connectors be used in medical applications?

A: Yes, both parts list medical applications in their approved use categories. Both are ROHS3 compliant and suitable for medical device integration.
