Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.1K.302.CLLC55Z is determined by the following critical parameters:

• Connector type must be receptacle with female sockets
• Position count must equal 2
• Termination method must be solder cup
• Fastening mechanism must be push-pull
• Shielding configuration must be shielded
• Cable opening dimensions must accommodate 5.10mm ~ 5.50mm range
• Insert material must be PEEK
• Contact finish must be gold-plated
• RoHS3 compliance is required

The substitute part K21K0C-P02LPH0-550S from ODU meets these core functional requirements. Variations in current rating, operating temperature range, and shell finish specifications represent acceptable trade-offs based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.302.CLLC55Z and K21K0C-P02LPH0-550S maintain Active product status and ROHS3 compliance. Selection between these parts depends on application-specific requirements:

The PHG.1K.302.CLLC55Z supports higher current capacity (15A versus 12A) and extended operating temperature range (-55°C to 200°C versus -40°C to 120°C). Applications requiring these extended specifications should utilize the LEMO part.

The K21K0C-P02LPH0-550S provides equivalent functionality for applications within its rated parameters and offers the additional feature of strain relief. Both parts achieve IP68 waterproof rating and utilize identical contact finish and insert materials.

Frequently Asked Questions (FAQ)

Q: Can K21K0C-P02LPH0-550S replace PHG.1K.302.CLLC55Z in all applications?

A: Substitution is valid only when application current requirements do not exceed 12A and operating temperatures remain within -40°C to 120°C. Applications requiring the full 15A rating or extended temperature range require the original PHG.1K.302.CLLC55Z specification.

Q: Are the cable opening dimensions compatible between these parts?

A: Both parts accommodate cable diameters within the 5.10mm ~ 5.50mm range. The ODU part specifies a slightly lower minimum (5.00mm), providing broader cable compatibility within this range.

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

A: The PHG.1K.302.CLLC55Z uses chrome plating directly on brass. The K21K0C-P02LPH0-550S uses chrome plating over a nickel intermediate layer. Both finishes provide corrosion resistance appropriate for IP68-rated applications.

Q: Do both parts require identical solder cup termination procedures?

A: Both parts utilize solder cup termination with identical insert material (PEEK) and gold contact finish. Termination procedures follow standard solder cup connector practices for both manufacturers.

Q: What is the inventory status for these parts?

A: PHG.1K.302.CLLC55Z maintains 1165 pieces in stock. K21K0C-P02LPH0-550S maintains 801 pieces in stock, both listed as new original inventory.
