Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.1K.308.CLLC45Z is determined by the following critical parameters:

• Connector Configuration: Receptacle with female sockets, 8-position, solder cup termination
• Mechanical Interface: Push-pull fastening mechanism with shielded construction
• Electrical Performance: Current rating and contact finish (gold plating for mating surfaces)
• Environmental Protection: Ingress protection rating (IP66/IP68 minimum)
• Termination Method: Solder cup for direct PCB or cable assembly attachment
• Compliance: ROHS3 compliance and REACH unaffected status

The substitute part K21K0C-P08LFG0-450S meets these core substitution criteria through equivalent connector type, position count, termination method, fastening mechanism, and shielding configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.308.CLLC45Z and K21K0C-P08LFG0-450S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The K21K0C-P08LFG0-450S provides higher current capacity (7.5A versus 5A) and meets IP68 waterproof specifications. However, the PHG.1K.308.CLLC45Z supports an extended operating temperature range (-55°C to 200°C) compared to the substitute (-40°C to 120°C). Selection between these parts depends on application-specific requirements for temperature extremes and current handling capacity. Both parts maintain equivalent mechanical interfaces, termination methods, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can K21K0C-P08LFG0-450S replace PHG.1K.308.CLLC45Z in all applications?

A: Substitution is valid when application requirements do not exceed the K21K0C-P08LFG0-450S operating temperature range (-40°C to 120°C) and current demand does not exceed 7.5A. Both connectors share identical mechanical interfaces, 8-position configuration, solder cup termination, and push-pull fastening.

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range (PHG.1K.308.CLLC45Z: -55°C to 200°C; K21K0C-P08LFG0-450S: -40°C to 120°C), current rating (5A versus 7.5A), and shell finish (chrome versus chrome over nickel). Both maintain equivalent ingress protection, shielding, and contact finish specifications.

Q: Are cable opening dimensions compatible between these parts?

A: Cable opening ranges are nearly identical (PHG.1K.308.CLLC45Z: 4.10mm–4.50mm; K21K0C-P08LFG0-450S: 4.00mm–4.50mm), ensuring compatible cable assembly integration for standard cable gauges within these specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PHG.1K.308.CLLC45Z and K21K0C-P08LFG0-450S are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings, suitable for standard storage and handling conditions.

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

A: The PHG.1K.308.CLLC45Z features chrome plating on brass, while the K21K0C-P08LFG0-450S uses chrome over nickel plating on brass. Both finishes provide corrosion resistance; the nickel underplate in the substitute offers additional protection in certain environmental conditions.
