Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.1K.302.CLLC45Z is determined by the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets, 2-position arrangement
• Termination Method: Solder cup termination for direct PCB or cable assembly
• Fastening Mechanism: Push-pull coupling system
• Shielding: Shielded design for EMI/RFI protection
• Contact Material & Finish: Gold-plated mating surfaces for reliable electrical connection
• Ingress Protection: IP66/IP68 rating for dust and water resistance
• Mechanical Compatibility: Cable opening range and mounting type (free-hanging, in-line)
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The identified substitute part K21K0C-P02LPH0-450S from ODU meets the core functional requirements of a 2-position, shielded, female socket receptacle with solder cup termination and push-pull fastening. Both parts maintain gold contact finish, shielded construction, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.302.CLLC45Z and K21K0C-P02LPH0-450S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The PHG.1K.302.CLLC45Z provides a wider operating temperature range (-55°C to 200°C) and higher current rating (15A), making it suitable for high-temperature or high-power applications. The K21K0C-P02LPH0-450S operates within -40°C to 120°C with a 12A current rating, appropriate for standard industrial and medical environments.

Both connectors feature identical core functionality: 2-position female socket receptacles with solder cup termination, push-pull fastening, shielded construction, gold contact finish, and PEEK inserts. Cable opening ranges overlap substantially (4.00mm to 4.50mm), ensuring mechanical compatibility for most cable assemblies.

Selection between these parts should be based on application-specific requirements for operating temperature range and current capacity. Where the PHG.1K.302.CLLC45Z specifications exceed application requirements, the K21K0C-P02LPH0-450S provides a functionally equivalent alternative.

Frequently Asked Questions (FAQ)

Q: Can the K21K0C-P02LPH0-450S directly replace the PHG.1K.302.CLLC45Z in all applications?

A: Direct substitution is valid when application operating temperature remains within -40°C to 120°C and current requirements do not exceed 12A. The PHG.1K.302.CLLC45Z is required for applications exceeding these parameters.

Q: Are the cable opening specifications compatible between these two connectors?

A: Yes. The PHG.1K.302.CLLC45Z accepts cables 4.10mm to 4.50mm, while the K21K0C-P02LPH0-450S accepts 4.00mm to 4.50mm. The overlapping range (4.10mm to 4.50mm) ensures compatibility for standard cable assemblies.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the difference in shell finish between these connectors?

A: The PHG.1K.302.CLLC45Z features chrome plating on brass, while the K21K0C-P02LPH0-450S features chrome over nickel plating on brass. Both provide corrosion resistance suitable for IP66/IP68 applications.

Q: Are solder cup terminations identical between these parts?

A: Both connectors use solder cup termination for direct PCB or cable assembly. Solder cup dimensions and specifications are determined by the 2-position configuration and should be verified against assembly equipment specifications.

Q: Which connector is better for medical applications?

A: The K21K0C-P02LPH0-450S is specifically listed for medical applications. The PHG.1K.302.CLLC45Z does not specify medical applications in the provided data. Application-specific certifications should be verified with manufacturers.
