Key Parameters

Substitute Part Grouping Explanation

The substitute part K11MA7-P14LCC0-5250 (ODU MEDI-SNAP®) qualifies as an equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 14
• Termination method: Solder Cup
• Fastening type: Push-Pull, Detent Lock
• Mounting type: Free Hanging (In-Line)
• Shell material: Polysulfone (PSU)
• Contact finish: Gold
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Ingress protection: IP50 - Dust Protected
• Insert material: Polyetheretherketone (PEEK)
• RoHS compliance: ROHS3 Compliant

These parameters define the functional and mechanical compatibility required for direct substitution in applications using the PRA.M1.4GL.LC52V.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M1.4GL.LC52V and K11MA7-P14LCC0-5250 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The ODU substitute provides a current rating of 2.5A compared to the LEMO part's 2A rating, offering additional margin in applications with moderate current demands. The operating temperature range of the LEMO part extends to 150°C, while the ODU substitute operates to 120°C. Selection between these parts should be based on specific application temperature requirements and current specifications. Both connectors maintain identical mechanical and electrical interface characteristics, including 14-position configuration, solder cup termination, and push-pull detent lock fastening.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P14LCC0-5250 be used as a direct replacement for PRA.M1.4GL.LC52V?

A: Yes, the K11MA7-P14LCC0-5250 is mechanically and electrically compatible for applications operating within -50°C to 120°C. Applications requiring operation above 120°C must use the PRA.M1.4GL.LC52V.

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

A: Compatibility is determined by 14-position configuration, female socket receptacle type, solder cup termination, push-pull detent lock fastening, M14/1 shell size equivalence, polysulfone shell material, gold contact finish, and IP50 ingress protection rating.

Q: Does the higher current rating of the ODU part affect compatibility?

A: No. The 2.5A rating of the ODU substitute exceeds the 2A requirement of the LEMO part, providing additional design margin without affecting mechanical or electrical interface compatibility.

Q: Are there packaging differences between these parts?

A: The LEMO part is supplied in standard packaging, while the ODU substitute is supplied in bulk packaging. This does not affect connector functionality or compatibility.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for industrial, medical, and automotive applications.
