PRG.M1.4GL.LC65GZ Equivalent & Substitute Parts

Part Overview

The PRG.M1.4GL.LC65GZ is a 14-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This connector is classified as a push-pull circular plastic connector with IP50 ingress protection, designed for free-hanging inline mounting applications. The part is currently active in production with 766 units in stock.

Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, when bulk packaging requirements differ, or when application-specific feature enhancements are required while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRG.M1.4GL.LC65GZ is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 14
• Termination method: Solder cup
• Fastening mechanism: Push-pull engagement
• Shell material: Polysulfone (PSU)
• Contact finish: Gold plating on mating surfaces
• Ingress protection rating: IP50
• Cable opening dimensions: 0.209" ~ 0.256" (5.30mm ~ 6.50mm)
• Insert material: Polyetheretherketone (PEEK)
• Mounting configuration: Free hanging inline

Allowable Variations:

• Current rating: Substitute parts may exceed the 2A minimum rating
• Operating temperature upper limit: Substitute parts may have lower maximum operating temperature if minimum (-50°C) is maintained
• Fastening type: Additional detent lock features are permissible
• Packaging format: Bulk or alternative packaging does not affect functional compatibility
• Backshell features: Additional strain relief features are allowable
• Contact material composition: Variations in base material (e.g., brass vs. unspecified) do not affect substitution eligibility

The identified substitute part K21M07-P14LCC0-657S from ODU meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

PRG.M1.4GL.LC65GZ (LEMO) is the primary specification. This part is active in production with confirmed inventory availability (766 units in stock). No product status concerns exist.

K21M07-P14LCC0-657S (ODU) is a qualified functional equivalent. Selection of this substitute is appropriate when:

• LEMO part availability is constrained
• Bulk packaging format is required for high-volume applications
• Enhanced current capacity (2.5A vs. 2A) provides design margin
• Additional strain relief features are beneficial for mechanical robustness
• RoHS3 and REACH compliance documentation is required for regulated supply chains

Temperature Operating Range Consideration: The ODU substitute operates to 120°C maximum, compared to 150°C for the LEMO part. Applications requiring sustained operation above 120°C must use the LEMO PRG.M1.4GL.LC65GZ.

Detent Lock Feature: The ODU part includes an additional detent lock mechanism beyond the standard push-pull fastening. This feature does not prevent substitution but adds mechanical retention capability.

Both parts share identical electrical and mechanical core specifications: 14-position solder cup receptacle, gold-plated contacts, IP50 protection, PSU shell construction, PEEK insert material, and identical cable opening dimensions.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P14LCC0-657S replace PRG.M1.4GL.LC65GZ in all applications?

A: K21M07-P14LCC0-657S is a functional equivalent for applications operating at temperatures up to 120°C. Applications requiring operation above 120°C must use PRG.M1.4GL.LC65GZ, which is rated to 150°C.

Q: What is the significance of the detent lock feature on the ODU substitute?

A: The detent lock provides additional mechanical retention beyond the standard push-pull engagement. This feature is compatible with mating connectors designed for standard push-pull operation and does not prevent substitution.

Q: Are the solder cup terminations identical between the two parts?

A: Both parts use solder cup termination. The cable opening dimensions are identical (0.209" ~ 0.256" / 5.30mm ~ 6.50mm), ensuring compatibility with the same cable gauges and assembly processes.

Q: Does the higher current rating of the ODU part (2.5A vs. 2A) affect compatibility?

A: No. The higher current rating of K21M07-P14LCC0-657S provides additional capacity and does not create compatibility issues. The substitute can safely carry currents up to 2.5A, exceeding the 2A requirement of the LEMO part.

Q: What packaging differences exist between these parts?

A: PRG.M1.4GL.LC65GZ packaging is not specified in the data. K21M07-P14LCC0-657S is supplied in bulk packaging. Packaging format does not affect functional compatibility; it only impacts order quantities and handling procedures.

Q: Are both parts suitable for medical device applications?

A: Both parts list medical applications in their application scope. K21M07-P14LCC0-657S includes RoHS3 compliance and REACH unaffected status, providing additional regulatory documentation for medical supply chain requirements.

Q: What is the shell size designation for these connectors?

A: PRG.M1.4GL.LC65GZ uses shell size M14. K21M07-P14LCC0-657S uses shell size 1 in the ODU MEDI-SNAP® series. These designations are manufacturer-specific nomenclature for the same physical 14-position connector form factor.

Q: Can these connectors be used in automotive applications?

A: PRG.M1.4GL.LC65GZ explicitly lists automotive applications. K21M07-P14LCC0-657S lists industrial and medical applications. Automotive suitability for the ODU part must be verified against specific automotive qualification requirements for the application.
