Engineering Selection Recommendations

For New Designs and Production: Part 2-1445098-4 is the recommended selection for all new applications. This part maintains complete electrical and mechanical compatibility with 1445098-4 while offering active product status and ROHS3 compliance certification. The transition from Tin-Lead to Tin contact finish on the post does not affect functional performance within the specified operating parameters.

For Legacy System Maintenance: Part 1445098-4 remains functionally equivalent for existing installations where RoHS compliance is not a regulatory requirement. Direct substitution is mechanically and electrically valid due to identical connector geometry, pitch spacing, voltage rating, and temperature operating range.

Compliance Considerations: Organizations subject to RoHS3 regulations must transition to part 2-1445098-4. The obsolete status of 1445098-4 indicates TE Connectivity has discontinued production in favor of the compliant equivalent.

Frequently Asked Questions (FAQ)

Q: Can 2-1445098-4 be used as a direct replacement for 1445098-4 in existing PCB designs?

A: Yes. Both parts share identical mounting footprints, pitch spacing (0.118" / 3.00mm), connector geometry, and electrical ratings. No PCB redesign is required for substitution.

Q: What is the difference between the contact finishes on these parts?

A: The main part (1445098-4) uses Tin-Lead finish on the solder post, while the substitute (2-1445098-4) uses Tin finish. Both finishes provide equivalent solder joint reliability and meet the 100.0µin (2.54µm) thickness specification. The Tin finish on the substitute reflects modern lead-free manufacturing standards.

Q: Are there any performance differences between these connectors?

A: No. Both parts operate identically within the specified voltage (250V), temperature (-40°C ~ 105°C), and current rating parameters. Electrical performance, mechanical retention, and board lock functionality are equivalent.

Q: Why is 1445098-4 listed as obsolete?

A: TE Connectivity has transitioned production to 2-1445098-4, which offers ROHS3 compliance and improved regulatory alignment. The obsolete designation indicates the original part is no longer manufactured.

Q: What packaging is available for the substitute part?

A: Part 2-1445098-4 is supplied in Tray packaging. Packaging format does not affect connector performance or compatibility.

Q: Can these parts be intermixed in the same assembly?

A: Yes. Both parts are mechanically and electrically interchangeable. They can be used together in the same board assembly without functional impact.

Q: Is the Micro MATE-N-LOK series designation the same for both parts?

A: Yes. Both parts belong to the Micro MATE-N-LOK series and maintain full series compatibility.
