Frequently Asked Questions (FAQ)

Q: Can the 1000143445 directly replace the 1000141445 in existing designs?

A: Both components maintain ZQSFP+ connector compatibility and share the 100014 base product series. However, the substitute introduces mounting type (through hole, right angle) and termination method (press-fit) specifications not detailed in the main part. Design verification is required to confirm mechanical fit and PCB layout compatibility.

Q: What is the significance of the heat sink feature in the substitute part?

A: The 1000143445 incorporates integrated heat sink and EMI shielding features. These represent functional enhancements over the spring finger assembly design of the main part, providing improved thermal dissipation and electromagnetic interference mitigation for high-speed ZQSFP+ applications.

Q: Are both parts RoHS compliant?

A: Yes. The main part 1000141445 carries RoHS Compliant status with MSL 1. The substitute 1000143445 maintains RoHS compliance under EAR99 ECCN classification, meeting current environmental and regulatory requirements.

Q: What is the inventory status for these parts?

A: The main part 1000141445 has 1044 pieces in stock but is classified as obsolete. The substitute 1000143445 has 1060 pieces in stock and maintains active product status, ensuring continued availability for new production and field service applications.

Q: How do the termination methods differ between these parts?

A: The main part 1000141445 uses a spring finger assembly configuration. The substitute 1000143445 employs press-fit termination with through-hole, right-angle mounting. This represents a transition to current manufacturing standards and assembly processes.
