Key Parameters

Substitute Part Grouping Explanation

Substitution of the PAA.M0.2GL.AC39J with the S11MA7-P02MPH0-3940 is based on the following alignment of critical parameters:

Matched Parameters:

• Connector type: Plug, Male Pins
• Number of positions: 2
• Termination method: Solder Cup
• Mounting configuration: Free Hanging (In-Line)
• Contact finish: Gold
• Shell material: Polysulfone (PSU)
• Ingress protection: IP50 - Dust Protected
• Cable opening range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Insert material: Polyetheretherketone (PEEK)
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

• Shell size insert: M02 (PAA.M0.2GL.AC39J) vs. 1 (S11MA7-P02MPH0-3940)
• Fastening type: Push-Pull, Detent Lock (PAA.M0.2GL.AC39J) vs. Push-Pull (S11MA7-P02MPH0-3940)
• Current rating: 10A (PAA.M0.2GL.AC39J) vs. 14A (S11MA7-P02MPH0-3940)
• Operating temperature range: -50°C ~ 150°C (PAA.M0.2GL.AC39J) vs. -50°C ~ 120°C (S11MA7-P02MPH0-3940)

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.2GL.AC39J and S11MA7-P02MPH0-3940 maintain active product status and full ROHS3 compliance. The S11MA7-P02MPH0-3940 offers higher current capacity at 14A compared to the 10A rating of the PAA.M0.2GL.AC39J, making it suitable for applications requiring increased current handling. However, the PAA.M0.2GL.AC39J supports an extended upper operating temperature of 150°C versus 120°C for the substitute. Selection between these parts should be based on specific application requirements for current capacity and temperature range. Both parts carry unlimited moisture sensitivity classification and maintain identical mechanical and electrical interface specifications for the 2-position solder cup configuration.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P02MPH0-3940 be used as a direct replacement for the PAA.M0.2GL.AC39J?

A: The S11MA7-P02MPH0-3940 shares the same connector type, pin count, termination method, and mechanical interface. However, differences exist in fastening mechanism (detent lock vs. standard push-pull), current rating (14A vs. 10A), and maximum operating temperature (120°C vs. 150°C). Substitution is valid only when application requirements fall within the S11MA7-P02MPH0-3940 specifications.

Q: What are the key compatibility factors for these connectors?

A: Compatibility is maintained through matching connector type (plug, male pins), 2-position configuration, solder cup termination, identical cable opening range (0.106" ~ 0.154"), and matching shell material (Polysulfone PSU). Both connectors provide IP50 ingress protection and use PEEK inserts.

Q: How do the current ratings differ between these parts?

A: The PAA.M0.2GL.AC39J is rated for 10A maximum current, while the S11MA7-P02MPH0-3940 is rated for 14A. Applications requiring current levels between 10A and 14A must use the S11MA7-P02MPH0-3940. Applications limited to 10A or below can use either part.

Q: Are there temperature range limitations for substitution?

A: The PAA.M0.2GL.AC39J operates from -50°C to 150°C, while the S11MA7-P02MPH0-3940 operates from -50°C to 120°C. Applications requiring operation above 120°C must use the PAA.M0.2GL.AC39J. Both parts support the full -50°C lower temperature limit.

Q: What is the difference in fastening mechanisms?

A: The PAA.M0.2GL.AC39J uses push-pull with detent lock fastening, providing positive mechanical locking. The S11MA7-P02MPH0-3940 uses standard push-pull fastening without detent lock. Applications requiring positive locking engagement should specify the PAA.M0.2GL.AC39J.

Q: Do both parts meet the same compliance standards?

A: Both the PAA.M0.2GL.AC39J and S11MA7-P02MPH0-3940 are ROHS3 compliant and carry unlimited moisture sensitivity classification (MSL 1). Both maintain REACH unaffected status and EAR99 ECCN classification.
