Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1445057-7 is determined by strict equivalence across the following critical parameters:

Connector Architecture: Rectangular connector, header type, male pin contact configuration, 7-position single-row layout with 3.00mm pitch spacing.

Mechanical Compatibility: Surface mount, right-angle mounting orientation with shrouded 4-wall design and locking ramp fastening mechanism.

Electrical Performance: 250V voltage rating, operating temperature range of -40°C to 105°C, and solder termination method.

Material Specifications: Brass contact material with polyamide/nylon insulation, UL94 V-0 flammability rating, and tin or tin-lead contact finish.

Packaging Consideration: The main part (1445057-7) is supplied in standard packaging, while substitute parts may be available in alternative packaging formats such as Tape & Reel (TR) without affecting functional compatibility.

The substitute part 2-1445057-7 meets all critical substitution criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-1445057-7 is functionally equivalent to the obsolete 1445057-7 across all critical electrical and mechanical parameters. Both parts share identical connector architecture, pitch spacing, mounting configuration, and operating specifications.

Product Status Advantage: The 2-1445057-7 carries Active product status, ensuring continued manufacturer support, availability, and technical documentation. The original 1445057-7 is classified as Obsolete, limiting future sourcing options.

Compliance Enhancement: The 2-1445057-7 is ROHS3 Compliant, meeting current regulatory requirements for restricted substances. The original part lists RoHS status as Not applicable, which may present compliance challenges in regulated applications.

Contact Finish Difference: The substitute part features Tin contact finish on both mating and post surfaces, compared to Tin-Lead finish on the original part. Both finishes maintain the same 100.0µin (2.54µm) thickness specification and are compatible with solder termination processes.

Packaging Format: The 2-1445057-7 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments. The original part uses standard packaging. This difference does not affect functional performance or electrical characteristics.

For new designs, maintenance applications, or production continuity, the 2-1445057-7 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the 1445057-7 and 2-1445057-7 mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch spacing (3.00mm), mounting orientation (surface mount, right angle), shrouding configuration (4-wall), and fastening mechanism (locking ramp). They occupy the same footprint and mate with identical receptacle connectors.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both contact finishes are compatible with solder termination and provide equivalent electrical performance. The Tin finish on the 2-1445057-7 reflects modern manufacturing standards and supports ROHS3 compliance. The Tin-Lead finish on the original part is a legacy specification. Contact finish thickness remains constant at 100.0µin (2.54µm) on both parts.

Q: Does the Tape & Reel packaging of the 2-1445057-7 affect compatibility?

A: No. Packaging format is a supply and handling consideration only. It does not alter the connector's electrical characteristics, mechanical dimensions, or functional performance. Tape & Reel packaging is standard for automated assembly processes.

Q: Why is the original 1445057-7 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The 2-1445057-7 is the active equivalent, ensuring ongoing availability and technical support.

Q: Is the 2-1445057-7 suitable for applications requiring ROHS compliance?

A: Yes. The 2-1445057-7 is ROHS3 Compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. The original 1445057-7 lists RoHS status as Not applicable, which may not satisfy compliance requirements in regulated markets.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the same temperature range of -40°C to 105°C and maintain identical voltage rating of 250V, UL94 V-0 flammability rating, and moisture sensitivity level (MSL 1 - Unlimited).

Q: Can the 2-1445057-7 be used as a direct replacement in existing assemblies?

A: Yes. The 2-1445057-7 is a direct functional equivalent with identical mating characteristics, electrical performance, and mechanical compatibility. It integrates into existing designs without modification.
