PHG.1K.302.CLLC50Z Equivalent & Substitute Parts

Part Overview

The PHG.1K.302.CLLC50Z is a 2-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This active product is designed for free-hanging inline applications requiring push-pull fastening and shielded construction. The connector is rated for 15A current capacity and operates across -55°C to 200°C, with IP66/IP68 ingress protection suitable for dust-tight and waterproof environments. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application requirements permit functional alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PHG.1K.302.CLLC50Z are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• 2-position connector configuration
• Female socket contact arrangement
• Solder cup termination method
• Push-pull fastening mechanism
• Gold contact finish for mating surfaces
• Shielded construction
• ROHS3 compliance and REACH unaffected status

Acceptable Variation Parameters:

• Shell size and insert designation (different manufacturers use different sizing nomenclature)
• Current rating (substitute may be lower or equal)
• Operating temperature range (substitute must cover application minimum requirements)
• Ingress protection rating (IP67 or IP68 acceptable for IP66/IP68 applications)
• Insert material composition (PEEK or PPS both acceptable for electrical and mechanical performance)
• Backshell material and plating specifications

The two identified substitutes meet these criteria with documented trade-offs in current capacity and temperature range that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

PHG.1K.302.CLLC50Z (LEMO) - Primary Part Active product status with full inventory availability. Recommended for applications requiring the complete specified performance envelope: 15A current capacity, -55°C to 200°C operating range, and IP66/IP68 ingress protection. ROHS3 compliant and REACH unaffected.

MMI-M1FG02S52B-IP67 (Adam Tech) - Limited Substitution Active product with adequate inventory. Suitable only for applications where current requirements do not exceed 9A and operating temperature remains within -55°C to 150°C. Connector type is plug configuration rather than receptacle, requiring mating interface compatibility verification. Unshielded construction differs from shielded primary part. ROHS3 compliant and REACH unaffected. Lower voltage rating (300V) must be confirmed acceptable for application.

K21K0C-P02LPH0-500S (ODU) - Preferred Substitute Active product with strong inventory availability. Maintains receptacle configuration and shielded construction matching primary part. Suitable for applications where current requirements do not exceed 12A and operating temperature range -40°C to 120°C is acceptable. IP68 ingress protection exceeds IP66/IP68 specification. ROHS3 compliant and REACH unaffected. Cable opening specification (0.177" to 0.197" / 4.50mm to 5.00mm) is compatible with primary part specification (0.181" to 0.197" / 4.60mm to 5.00mm).

Frequently Asked Questions (FAQ)

Q: Can MMI-M1FG02S52B-IP67 be used as a direct replacement for PHG.1K.302.CLLC50Z? A: No. While both are 2-position female socket solder cup connectors with push-pull fastening, the Adam Tech part is a plug configuration versus the LEMO receptacle. Additionally, the 9A current rating is lower than the 15A primary specification, and the unshielded design differs from the shielded primary part. Mating interface compatibility must be verified before selection.

Q: Is K21K0C-P02LPH0-500S a suitable substitute? A: K21K0C-P02LPH0-500S is suitable for applications where the 12A current limit and -40°C to 120°C operating range are acceptable. The receptacle configuration and shielded construction match the primary part. Cable opening specifications are compatible. IP68 protection exceeds the IP66/IP68 requirement.

Q: What are the key differences between the three connectors? A: The primary differences are connector type (receptacle vs. plug), current rating (15A vs. 9A vs. 12A), operating temperature range (-55°C to 200°C vs. -55°C to 150°C vs. -40°C to 120°C), shielding (shielded vs. unshielded vs. shielded), and ingress protection rating (IP66/IP68 vs. IP67 vs. IP68).

Q: Are all three parts RoHS and REACH compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component sourcing.

Q: What is the significance of the cable opening specification? A: Cable opening specification defines the acceptable cable diameter range for proper strain relief and backshell engagement. K21K0C-P02LPH0-500S (0.177" to 0.197" / 4.50mm to 5.00mm) overlaps with PHG.1K.302.CLLC50Z (0.181" to 0.197" / 4.60mm to 5.00mm) in the 4.60mm to 5.00mm range, ensuring mechanical compatibility for cables within this overlap.

Q: Can these connectors be used interchangeably in high-temperature applications? A: No. The PHG.1K.302.CLLC50Z operates to 200°C, while K21K0C-P02LPH0-500S is limited to 120°C and MMI-M1FG02S52B-IP67 to 150°C. Part selection must match application temperature requirements.

Q: What is the difference between IP67 and IP68 ratings? A: IP67 provides dust-tight and waterproof protection (temporary immersion). IP68 provides dust-tight and waterproof protection (continuous immersion). Both exceed IP66 (dust-tight, water-resistant) specification of the primary part.
