Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1445050-4 is based on electrical and mechanical parameter equivalence within the Micro MATE-N-LOK series. The substitute part 2-1445050-4 maintains identical specifications across all critical functional parameters: connector type, contact configuration, mating pitch, position count, shrouding design, mounting method, voltage rating, and operating temperature range. Both parts share the same base product number (1445050) and series designation, confirming mechanical and electrical interchangeability.

The primary distinction between the main part and its substitute is product status and compliance certification. The substitute part 2-1445050-4 is active in production and carries RoHS Compliant certification, whereas the original 1445050-4 is obsolete with undefined RoHS status. Additionally, the substitute features tin contact finish on both mating and post surfaces, compared to the tin-lead finish of the original part. Both finishes meet the specified 100.0µin (2.54µm) thickness requirement and maintain equivalent electrical performance.

Substitution eligibility is determined by the following parameters:

• Connector type and contact configuration
• Mating pitch and position count
• Mounting and termination methods
• Voltage and temperature ratings
• Shrouding and mechanical form factor
• Flammability and material specifications

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-1445050-4 is the direct equivalent for the obsolete 1445050-4. Both components are manufactured by TE Connectivity within the Micro MATE-N-LOK series and share identical electrical and mechanical specifications. The substitute part is recommended for all new designs and production applications due to its active product status and superior compliance certification.

The 2-1445050-4 carries RoHS Compliant certification, meeting current regulatory requirements for electronic component manufacturing and end-of-life management. The original 1445050-4 has undefined RoHS status, which may present compliance challenges in regulated markets and applications subject to environmental directives.

Contact finish composition differs between the two parts: the original uses tin-lead plating while the substitute uses tin plating. Both finishes are applied at equivalent thickness (100.0µin / 2.54µm) and maintain the same electrical conductivity and solderability characteristics required for press-fit and solder termination methods. The tin finish of the substitute part aligns with modern manufacturing standards and lead-free soldering processes.

Inventory availability strongly favors the substitute part, with 26,293 units in stock compared to 1,100 units of the obsolete original. The substitute is supplied in tray packaging, suitable for automated assembly and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Are the 1445050-4 and 2-1445050-4 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including connector type, position count, mating pitch (0.118" / 3.00mm), shrouding design (4-wall), mounting method (through-hole), and form factor. They are direct mechanical substitutes within the Micro MATE-N-LOK series.

Q: What is the difference in contact finish between these parts?

A: The original 1445050-4 features tin-lead contact finish, while the substitute 2-1445050-4 uses tin finish. Both are applied at 100.0µin (2.54µm) thickness. The tin finish of the substitute part is compatible with modern lead-free soldering processes and press-fit termination methods.

Q: Does the substitute part meet RoHS requirements?
