Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.307.CLLC55Z and K21K0C-P07LFG0-550S are active production parts with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications.

The PHG.1K.307.CLLC55Z supports an extended operating temperature range of -55°C to 200°C, making it suitable for high-temperature applications. The K21K0C-P07LFG0-550S operates within -40°C to 120°C, which is appropriate for industrial, medical, military, and testing equipment applications within this thermal envelope.

The K21K0C-P07LFG0-550S provides a higher current rating of 7.5A compared to 7A, and includes integrated strain relief features. Cable opening tolerances overlap within the 5.10mm to 5.17mm range, ensuring mechanical compatibility for standard cable gauges.

Selection between these parts should be based on specific application temperature requirements and the necessity of extended thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the K21K0C-P07LFG0-550S replace the PHG.1K.307.CLLC55Z in all applications?

A: Substitution is valid for applications operating within -40°C to 120°C. Applications requiring operation below -40°C or above 120°C must use the PHG.1K.307.CLLC55Z due to its extended temperature rating of -55°C to 200°C.

Q: Are the cable opening specifications compatible?

A: Yes. The PHG.1K.307.CLLC55Z specifies 5.10mm to 5.50mm, while the K21K0C-P07LFG0-550S specifies 5.00mm to 5.50mm. The overlap range of 5.10mm to 5.50mm ensures mechanical compatibility for standard cable sizes.

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

A: The PHG.1K.307.CLLC55Z uses chrome plating directly on brass. The K21K0C-P07LFG0-550S uses chrome over nickel plating on brass, providing an additional corrosion barrier layer.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component sourcing.

Q: What is the current rating difference?

A: The PHG.1K.307.CLLC55Z is rated for 7A, while the K21K0C-P07LFG0-550S is rated for 7.5A. The higher rating of the substitute part does not restrict its use in 7A applications.

Q: Are both connectors shielded?

A: The PHG.1K.307.CLLC55Z is specified as shielded. Shielding information for the K21K0C-P07LFG0-550S is not provided in the available specifications.
