• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)

Mechanical Compatibility:

• Mounting configuration (Surface Mount, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Series designation (Micro MATE-N-LOK)

Regulatory & Compliance Factors:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)
• RoHS compliance status
• REACH compliance status

The substitute part 2-1445091-3 maintains full electrical and mechanical equivalence while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-1445091-3 is the direct functional equivalent of the obsolete 1445091-3. Both parts share identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, mounting style, and operating characteristics.

Primary Selection Basis:

The 2-1445091-3 is recommended for new designs and production applications due to its active product status. The obsolete 1445091-3 should be replaced in all new applications.

Compliance Advantages:

The substitute part 2-1445091-3 provides superior regulatory compliance:

• ROHS3 compliant (versus RoHS non-compliant for the main part)
• REACH unaffected status (versus REACH affected for the main part)
• Lead-free post finish (Tin versus Tin-Lead), aligning with modern manufacturing standards

Packaging Consideration:

The substitute is supplied in Cut Tape (CT) packaging, providing standard handling and automated assembly compatibility.

Functional Equivalence:

All electrical parameters remain identical: 250V voltage rating, -40°C to 105°C operating temperature range, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity. The contact finish specifications, insulation materials, and mechanical dimensions are fully equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 2-1445091-3 be used as a direct replacement for the 1445091-3 in existing designs?

A: Yes. The 2-1445091-3 maintains full electrical and mechanical equivalence with the 1445091-3. All critical parameters including pitch, number of positions, voltage rating, operating temperature range, and mounting configuration are identical. The parts are functionally interchangeable.

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

A: The main part 1445091-3 uses Tin-Lead post finish, while the substitute 2-1445091-3 uses Tin post finish. Both maintain the same contact finish thickness of 100.0µin (2.54µm). The Tin finish on the substitute represents a lead-free upgrade aligned with current manufacturing standards and RoHS3 compliance.

Q: Why is the 1445091-3 listed as obsolete?

A: The 1445091-3 is classified as obsolete due to its RoHS non-compliant status and REACH-affected designation. The 2-1445091-3 supersedes it with improved regulatory compliance while maintaining full functional equivalence.

Q: Are there any compatibility issues when switching from 1445091-3 to 2-1445091-3?

A: No compatibility issues exist. Both parts are from the same Micro MATE-N-LOK series with identical shrouding, termination method, and mechanical dimensions. The parts are pin-for-pin and footprint-compatible.

Q: What packaging formats are available for the substitute part?

A: The 2-1445091-3 is supplied in Cut Tape (CT) packaging, which is standard for automated assembly and component handling.

Q: Do both parts have the same current rating?

A: Yes. Both the 1445091-3 and 2-1445091-3 have current ratings that vary by wire gauge, maintaining identical electrical performance characteristics.

Q: Is the 2-1445091-3 suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 105°C, ensuring thermal compatibility in all applications.

Q: What is the moisture sensitivity level for the substitute part?

A: The 2-1445091-3 has MSL 1 (Unlimited) moisture sensitivity level, identical to the main part, indicating no special moisture control requirements during storage or handling.
