Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRG.M0.9GL.LC39Z is determined by strict alignment of the following critical parameters:

• Connector type: Receptacle with female sockets
• Position count: 9 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 minimum
• Insert material: Polyetheretherketone (PEEK)
• Cable opening range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Regulatory compliance: ROHS3 and REACH requirements

The substitute part K21M07-P09LCC0-397S from ODU meets these core substitution criteria. Variations in secondary parameters such as current rating, maximum operating temperature, and series designation are documented in the parameter comparison table to support engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.9GL.LC39Z and K21M07-P09LCC0-397S maintain active product status and full compliance with ROHS3 and REACH regulatory requirements. Selection between these parts should be based on application-specific requirements:

The PRG.M0.9GL.LC39Z supports a maximum operating temperature of 150°C and a current rating of 3A, making it suitable for higher-temperature and higher-current applications.

The K21M07-P09LCC0-397S operates to a maximum of 120°C with a 2.75A current rating and includes integrated strain relief in addition to the backshell, providing enhanced mechanical protection in applications subject to cable flexing or vibration.

Both connectors share identical mechanical interfaces, contact finishes, ingress protection ratings, and termination methods, ensuring functional interchangeability within their respective thermal and current operating envelopes.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P09LCC0-397S be used as a direct replacement for PRG.M0.9GL.LC39Z?

A: Yes, within application constraints. Both connectors are 9-position receptacles with identical solder cup termination, push-pull detent fastening, and mechanical dimensions. The substitute part is suitable for applications operating at or below 120°C and 2.75A. Applications requiring operation above 120°C or exceeding 2.75A current must use the PRG.M0.9GL.LC39Z.

Q: What are the key differences between these two connectors?

A: The primary differences are maximum operating temperature (150°C vs. 120°C), current rating (3A vs. 2.75A), and the inclusion of strain relief on the ODU part. All other mechanical, electrical, and regulatory parameters are equivalent.

Q: Are both parts available in the same packaging?

A: The PRG.M0.9GL.LC39Z is supplied in standard packaging with 693 units in stock. The K21M07-P09LCC0-397S is supplied in bulk packaging with 1018 units in stock. Packaging format does not affect connector functionality or interchangeability.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (unlimited) moisture sensitivity ratings.

Q: What is the cable opening specification for both connectors?

A: Both connectors accept cables with outer diameters between 0.106" and 0.154" (2.70mm to 3.90mm), ensuring compatibility with standard cable sizes.
