Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRG.M1.4GL.LC52Z are identified based on strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets
• Position Count: 14 positions
• Termination Method: Solder cup
• Fastening Mechanism: Push-pull with detent lock
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Ingress Protection: IP50 dust protection rating
• Cable Opening Range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part K21M07-P14LCC0-527S from ODU meets these core equivalence criteria, enabling direct functional replacement in applications where connector interchangeability is permitted by design specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M1.4GL.LC52Z and K21M07-P14LCC0-527S maintain active product status with full ROHS3 compliance and REACH unaffected regulatory standing. Selection between these parts should be based on the following documented parameters:

PRG.M1.4GL.LC52Z (LEMO) is specified when the application requires the extended operating temperature range of -50°C to 150°C and the 2A current rating meets system requirements.

K21M07-P14LCC0-527S (ODU) is specified when the application operates within the -50°C to 120°C temperature range and benefits from the higher 2.5A current rating. This part includes strain relief features in addition to backshell provisions.

Both connectors are suitable for automotive, industrial, medical, and testing equipment applications. Part selection should align with documented application temperature requirements and current specifications.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P14LCC0-527S replace PRG.M1.4GL.LC52Z in all applications?

A: Substitution is valid when the application operates within the -50°C to 120°C temperature range. Applications requiring operation above 120°C must use the PRG.M1.4GL.LC52Z due to its extended upper temperature limit of 150°C.

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

A: Both connectors share identical 14-position configuration, solder cup termination, push-pull detent lock fastening, PSU shell material, gold contact finish, IP50 ingress protection, and cable opening specifications. These parameters ensure mechanical and electrical compatibility.

Q: Are there differences in current handling capacity?

A: The PRG.M1.4GL.LC52Z is rated for 2A, while the K21M07-P14LCC0-527S is rated for 2.5A. Applications requiring current levels above 2A but within 2.5A may benefit from the ODU substitute part.

Q: What packaging considerations apply to these parts?

A: The PRG.M1.4GL.LC52Z is supplied in standard packaging with 874 units in current inventory. The K21M07-P14LCC0-527S is supplied in bulk packaging with 682 units in current inventory. Packaging format should be confirmed against procurement requirements.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and medical applications.
