Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRG.M1.4GL.LC65Z is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 14
• Termination: Solder Cup
• Fastening Type: Push-Pull, Detent Lock
• Mounting Type: Free Hanging (In-Line)
• Shell Material: Polysulfone (PSU)
• Contact Finish - Mating: Gold
• Ingress Protection: IP50 - Dust Protected
• Insert Material: Polyetheretherketone (PEEK)
• Shielding: Unshielded
• Cable Opening: 0.209" ~ 0.256" (5.30mm ~ 6.50mm)

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 2A
• Operating Temperature: Substitute must support the full range or a subset that includes critical application temperatures
• Manufacturer: Different manufacturers permitted if all mandatory parameters align
• Series designation: May differ between manufacturers

The substitute part K21M07-P14LCC0-657S (ODU MEDI-SNAP®) meets all mandatory matching criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M1.4GL.LC65Z and K21M07-P14LCC0-657S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

The K21M07-P14LCC0-657S substitute provides a current rating of 2.5A, which exceeds the 2A requirement of the primary part. This higher current capacity does not create incompatibility and may provide additional design margin in power distribution applications.

The operating temperature range of the substitute part extends to 120°C maximum, compared to 150°C for the primary part. Applications requiring sustained operation above 120°C must use the PRG.M1.4GL.LC65Z. For applications operating within -50°C to 120°C, the substitute part is functionally equivalent.

Both parts carry identical mechanical and electrical interface specifications, including shell size, contact finish, termination method, and ingress protection rating. Interchangeability is confirmed at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P14LCC0-657S be used as a direct replacement for PRG.M1.4GL.LC65Z?

A: Yes, for applications operating within the temperature range of -50°C to 120°C. Both parts share identical mechanical interfaces, electrical contact specifications, and termination methods. The substitute part's higher current rating (2.5A vs. 2A) does not create incompatibility.

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

A: The maximum operating temperature differs. The PRG.M1.4GL.LC65Z supports -50°C to 150°C, while the K21M07-P14LCC0-657S supports -50°C to 120°C. The substitute part also provides a higher current rating of 2.5A compared to 2A.

Q: Are both parts compliant with regulatory requirements?

A: Yes. Both the PRG.M1.4GL.LC65Z and K21M07-P14LCC0-657S are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for medical, industrial, and automotive applications.

Q: What does the 14-position specification mean?

A: The connector accommodates 14 individual signal or power contacts arranged within the circular shell. Both the primary and substitute parts maintain this 14-position configuration.

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

A: Yes. Both parts use solder cup termination with identical cable opening specifications (0.209" to 0.256" or 5.30mm to 6.50mm), ensuring compatible PCB layout and assembly processes.

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

A: Interchangeability is confirmed for mechanical and electrical interfaces. Design validation should confirm that the substitute part's maximum operating temperature of 120°C meets application requirements if the primary part's 150°C capability was specified.
