Parameter Comparison

Engineering Selection Recommendations

The 2-1445086-2 is the direct active equivalent for the obsolete 1445086-2. Selection of this substitute part is based on the following engineering criteria:

Product Status Alignment: The 2-1445086-2 maintains active product status, ensuring continued availability and manufacturer support. The original 1445086-2 is classified as obsolete, making the substitute necessary for new procurement cycles.

Electrical Equivalence: Both parts maintain identical voltage ratings (250V) and operating temperature ranges (-40°C ~ 105°C), ensuring functional compatibility in existing circuit designs without modification.

Mechanical Interchangeability: All critical mechanical parameters are identical, including pitch (0.118"/3.00mm), number of positions (2), mounting type (surface mount), and shrouding configuration (shrouded 4-wall). The components are directly interchangeable on printed circuit boards.

Material & Certification Compliance: Both parts meet UL94 V-0 flammability requirements and utilize identical contact materials (brass) and insulation materials (polyamide/nylon). The substitute part achieves ROHS3 compliance, providing enhanced environmental compliance compared to the original part.

Contact Finish Compatibility: The substitute part features tin post finish compared to the original tin-lead finish. This change reflects modern lead-free manufacturing standards while maintaining electrical performance and solder joint reliability.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. This packaging format is compatible with automated pick-and-place equipment.

Frequently Asked Questions (FAQ)

Q: Can the 2-1445086-2 be used as a direct replacement for the 1445086-2 in existing designs?

A: Yes. The 2-1445086-2 is a direct equivalent with identical electrical and mechanical specifications. All critical parameters including pitch, number of positions, voltage rating, operating temperature range, and physical dimensions are identical. The component can be substituted without circuit design modifications.

Q: What is the difference between the contact finish specifications?

A: The original 1445086-2 features tin-lead post finish, while the substitute 2-1445086-2 features tin post finish. Both finishes provide equivalent electrical performance and solder joint reliability. The tin finish reflects current lead-free manufacturing standards.

Q: Why is the substitute part supplied in Tape & Reel packaging?

A: Tape & Reel (TR) packaging is the standard format for surface mount components in automated assembly environments. This packaging format enables efficient pick-and-place machine operation and is compatible with standard SMT assembly processes.

Q: Does the ROHS3 compliance of the substitute part affect compatibility?

A: No. ROHS3 compliance indicates enhanced environmental compliance and does not affect electrical or mechanical compatibility. The substitute part meets or exceeds all regulatory requirements of the original part.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts maintain identical voltage ratings (250V), operating temperature ranges (-40°C ~ 105°C), and current handling capabilities. Thermal and electrical performance characteristics are equivalent.

Q: What is the significance of the "Micro MATE-N-LOK" series designation?

A: The Micro MATE-N-LOK series is a TE Connectivity connector family characterized by 3.00mm pitch, shrouded design, and locking ramp fastening. Both the original and substitute parts belong to this series, ensuring mechanical and electrical compatibility with other components in the series.

Q: Can the substitute part be used in applications requiring lead-free solder?

A: Yes. The tin post finish of the substitute part is compatible with lead-free solder processes. The original tin-lead finish is also compatible with lead-free solder, though the substitute part aligns with current lead-free manufacturing standards.
