PHG.1K.304.CLLC50Z Equivalent & Substitute Parts

Part Overview

The PHG.1K.304.CLLC50Z is a 4-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 10A current capacity and operates across -55°C to 200°C, with IP66/IP68 ingress protection suitable for dust-tight and waterproof environments. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative connector configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PHG.1K.304.CLLC50Z are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• 4-position configuration
• Female socket contacts
• Solder cup termination
• Push-pull fastening mechanism
• Gold contact finish
• Shielded construction
• ROHS3 compliance
• Solder cup cable opening range (0.177" to 0.197" / 4.50mm to 5.00mm)

Substitution Categories:

Direct Substitute (Connector Type Variation): MMI-M1FG04S52B-IP67 is classified as a plug configuration rather than receptacle, representing a mating pair alternative. This part maintains 4-position, female socket, solder cup, push-pull, and gold contact specifications, though with reduced current rating (8A vs. 10A) and lower maximum operating temperature (150°C vs. 200°C).

Similar Substitute (Receptacle Configuration): K21K0C-P04LJG0-500S maintains receptacle configuration with 4-position, female socket, solder cup, push-pull, shielded, and gold contact specifications. This part provides comparable cable opening range and operating temperature flexibility, though with reduced current rating (7.5A vs. 10A) and lower maximum operating temperature (120°C vs. 200°C).

Parameter Comparison

Engineering Selection Recommendations

PHG.1K.304.CLLC50Z (Primary Part): Select this part when maximum current capacity (10A) and extended operating temperature range (-55°C to 200°C) are required. The shielded receptacle configuration with IP66/IP68 protection is suitable for high-reliability applications demanding superior environmental sealing and thermal performance.

MMI-M1FG04S52B-IP67 (Direct Substitute): This Adam Tech plug configuration serves as a mating pair alternative when receptacle-to-plug connection is required. The unshielded design and reduced current rating (8A) and operating temperature ceiling (150°C) indicate suitability for less demanding thermal and EMI environments. ROHS3 compliance and active product status support continued availability.

K21K0C-P04LJG0-500S (Similar Substitute): This ODU MINI-SNAP® K receptacle maintains shielded construction and IP68 protection, making it suitable for applications where the primary part is unavailable. The reduced current rating (7.5A) and lower maximum operating temperature (120°C) require verification against application load and thermal requirements. Cable opening compatibility (0.177" to 0.197") overlaps with the primary part specification. ROHS3 compliance and active product status confirm regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can MMI-M1FG04S52B-IP67 directly replace PHG.1K.304.CLLC50Z?

A: No. MMI-M1FG04S52B-IP67 is a plug configuration, not a receptacle. It functions as a mating connector to a receptacle. Direct replacement requires a receptacle-type substitute such as K21K0C-P04LJG0-500S. The MMI part is suitable only when a plug-to-receptacle mating pair is required.

Q: What are the current rating implications when substituting?

A: The primary part PHG.1K.304.CLLC50Z is rated for 10A. Substitute MMI-M1FG04S52B-IP67 is rated for 8A, and K21K0C-P04LJG0-500S is rated for 7.5A. Applications requiring the full 10A capacity cannot use these substitutes without circuit redesign or parallel conductor configuration.

Q: Are there temperature limitations with the substitute parts?

A: Yes. The primary part operates from -55°C to 200°C. MMI-M1FG04S52B-IP67 operates to 150°C maximum, and K21K0C-P04LJG0-500S operates to 120°C maximum. Applications requiring operation above 150°C must use the primary PHG.1K.304.CLLC50Z part.

Q: Does shielding differ between parts?

A: Yes. PHG.1K.304.CLLC50Z and K21K0C-P04LJG0-500S are shielded. MMI-M1FG04S52B-IP67 is unshielded. Applications requiring EMI suppression or noise immunity must use shielded alternatives.

Q: What is the cable opening compatibility?

A: PHG.1K.304.CLLC50Z specifies 0.181" to 0.197" (4.60mm to 5.00mm). K21K0C-P04LJG0-500S specifies 0.177" to 0.197" (4.50mm to 5.00mm), providing overlap. MMI-M1FG04S52B-IP67 does not specify cable opening dimensions. Verify cable diameter compatibility before substitution.

Q: Are all parts RoHS3 compliant?

A: Yes. PHG.1K.304.CLLC50Z, MMI-M1FG04S52B-IP67, and K21K0C-P04LJG0-500S are all ROHS3 compliant and REACH unaffected, supporting regulatory requirements for restricted substance compliance.

Q: What ingress protection levels are available?

A: PHG.1K.304.CLLC50Z provides IP66/IP68. MMI-M1FG04S52B-IP67 provides IP67. K21K0C-P04LJG0-500S provides IP68. All three meet dust-tight and waterproof requirements, with IP68 offering the highest water immersion rating.
