Substitute Part Grouping Explanation

Substitute parts for the PHG.1K.307.CLLC50Z are identified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• 7-position connector configuration
• Female socket contact arrangement
• Solder cup termination method
• Push-pull fastening mechanism
• Shielded or unshielded construction compatibility
• Gold contact finish for mating surfaces
• Operating temperature range overlap
• Cable opening dimensional compatibility
• Current rating capability (minimum 5A)
• Ingress protection rating (IP67 or higher)
• ROHS3 compliance and REACH unaffected status

Substitute Parts Identified:

1. MMI-M1FG07S52B-IP67 (Adam Tech) – Direct manufacturer alternative with 7-position configuration, female sockets, solder cup termination, and push-pull fastening. Operates at -55°C to 150°C with 5A current rating and IP67 ingress protection.

2. K21K0C-P07LFG0-500S (ODU MINI-SNAP® K Series) – Similar receptacle configuration with 7-position female sockets, solder cup termination, and push-pull fastening. Operates at -40°C to 120°C with 7.5A current rating and IP68 ingress protection. Cable opening range 0.177" to 0.197" (4.50mm to 5.00mm) provides dimensional compatibility.

Parameter Comparison

Engineering Selection Recommendations

PHG.1K.307.CLLC50Z (LEMO) remains the primary specification when maximum operating temperature (-55°C to 200°C) and shielded construction are required. This part maintains the widest temperature operating range and integrated shielding for EMI-sensitive applications.

MMI-M1FG07S52B-IP67 (Adam Tech) serves as an alternative when connector type flexibility is acceptable. Note that this part is classified as a Plug configuration rather than Receptacle, which may require mating interface reconsideration. The 5A current rating is lower than the main part specification. Operating temperature range extends to -55°C, matching the lower temperature limit of the main part. IP67 ingress protection is suitable for dust-tight and waterproof applications, though lower than the main part's IP68 capability.

K21K0C-P07LFG0-500S (ODU MINI-SNAP® K) provides substitution when receptacle configuration and higher current capacity (7.5A) are priorities. Cable opening dimensions (0.177" to 0.197") overlap with the main part specification. IP68 ingress protection exceeds the main part requirement. Operating temperature range (-40°C to 120°C) is narrower than the main part, limiting use in extreme cold environments below -40°C or high-temperature applications above 120°C.

All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across procurement options.

Frequently Asked Questions (FAQ)

Q: Can MMI-M1FG07S52B-IP67 directly replace PHG.1K.307.CLLC50Z?

A: Direct replacement requires interface verification. MMI-M1FG07S52B-IP67 is classified as a Plug connector, while PHG.1K.307.CLLC50Z is a Receptacle. Both feature 7-position female sockets, solder cup termination, and push-pull fastening. However, the mating connector type must be confirmed compatible with your application's existing interface. Additionally, the 5A current rating of the Adam Tech part is lower than the 7A specification of the LEMO part.

Q: What are the temperature limitations when using K21K0C-P07LFG0-500S?

A: The ODU MINI-SNAP® K part operates from -40°C to 120°C, which is narrower than the LEMO part's -55°C to 200°C range. Applications requiring operation below -40°C or above 120°C must use the original PHG.1K.307.CLLC50Z specification.

Q: Are cable opening dimensions compatible across all three parts?

A: The LEMO PHG.1K.307.CLLC50Z specifies 0.181" to 0.197" (4.60mm to 5.00mm). The ODU K21K0C-P07LFG0-500S specifies 0.177" to 0.197" (4.50mm to 5.00mm), providing overlap within the upper range. The Adam Tech MMI-M1FG07S52B-IP67 does not provide cable opening specifications. Cable diameter verification is required before substitution.

Q: How do ingress protection ratings compare?

A: The LEMO part provides IP66/IP68 protection. The Adam Tech part provides IP67, and the ODU part provides IP68. All three ratings indicate dust-tight and waterproof construction. IP68 (ODU) exceeds the main part specification, while IP67 (Adam Tech) is intermediate. Application environment requirements determine the minimum acceptable rating.

Q: Are all parts RoHS3 compliant?

A: Yes. PHG.1K.307.CLLC50Z, MMI-M1FG07S52B-IP67, and K21K0C-P07LFG0-500S are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the current rating difference impact?

A: The LEMO part is rated for 7A, the ODU part for 7.5A, and the Adam Tech part for 5A. Applications requiring continuous current above 5A must use either the LEMO or ODU parts. The Adam Tech part is suitable only for applications with maximum sustained current of 5A or less.
