Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M1.0GL.LC52G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 10
• Termination method: Solder Cup
• Fastening type: Push-Pull, Detent Lock
• Mounting type: Free Hanging (In-Line)
• Shell material: Polysulfone (PSU)
• Contact finish: Gold
• Ingress protection: IP50 - Dust Protected
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Insert material: Polyetheretherketone (PEEK)
• Backshell: Present

Allowable Variation Parameters:

• Current rating: Minimum 2.75A (substitute may be lower than 3A if application permits)
• Operating temperature: Minimum upper limit of 120°C (substitute may have lower maximum than 150°C if application permits)
• Shell size designation: M10 or equivalent numeric designation (1) representing the same physical form factor

The ODU K11MA7-P10LCC0-5270 meets all mandatory matching criteria and qualifies as a direct substitute within the allowable variation parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M1.0GL.LC52G and K11MA7-P10LCC0-5270 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in industrial, medical, and testing equipment environments.

Selection between these parts should be based on application-specific requirements:

PRA.M1.0GL.LC52G (LEMO) is the primary choice when the application requires the full 3A current rating or operating temperatures above 120°C.

K11MA7-P10LCC0-5270 (ODU MEDI-SNAP®) is a qualified substitute when the application operates within 2.75A current limits and maximum temperatures of 120°C. This part is available in bulk packaging and represents an alternative sourcing option with equivalent mechanical and electrical compatibility.

Both parts maintain identical mechanical form factors, fastening mechanisms, and environmental protection ratings, ensuring direct interchangeability at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can the ODU K11MA7-P10LCC0-5270 be used as a direct replacement for the LEMO PRA.M1.0GL.LC52G?

A: Yes, provided the application does not exceed 2.75A current draw or require operating temperatures above 120°C. All mechanical and electrical interface parameters are equivalent.

Q: What is the primary difference between these two connectors?

A: The LEMO part supports 3A current rating and -50°C to 150°C operating range, while the ODU part is rated for 2.75A and -50°C to 120°C. All other specifications are identical.

Q: Are both parts suitable for medical applications?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. The ODU part is specifically designated for the MEDI-SNAP® series, which targets medical applications.

Q: What is the significance of the shell size designation M10 versus 1?

A: These designations represent the same physical form factor. M10 is the metric designation used by LEMO, while 1 is the numeric equivalent used by ODU for the same connector size.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Yes, at the connector interface level. Both parts feature identical push-pull detent lock fastening, 10-position configuration, and solder cup termination, ensuring mechanical and electrical compatibility.

Q: What packaging options are available?

A: The LEMO PRA.M1.0GL.LC52G is supplied in standard packaging with 1044 units in stock. The ODU K11MA7-P10LCC0-5270 is available in bulk packaging with 1117 units in stock.
