Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 745058-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 6A
• Voltage Rating: 125V
• Operating Temperature Range: -55°C ~ 105°C
• Contact Finish: Gold
• Contact Material: Phosphor Bronze
• Dielectric Material: Polyester
• Flange Feature: Housing/Shell (4-40)
• Material Flammability Rating: UL94 V-0

Substitute parts are classified into two categories: direct manufacturer equivalents and similar manufacturer alternatives. Direct equivalents maintain identical electrical and mechanical specifications with potential variations in compliance certifications. Similar manufacturer alternatives provide functional equivalence while originating from different manufacturers.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5745058-3 (Direct Equivalent): This part is a direct manufacturer equivalent from TE Connectivity AMP Connectors within the same AMPLIMITE HD-20 series. It maintains identical electrical and mechanical specifications to the 745058-3 across all critical parameters. The primary distinction is RoHS compliance status: the 5745058-3 is ROHS3 compliant, whereas the 745058-3 is RoHS non-compliant. Selection of the 5745058-3 is appropriate for applications requiring RoHS3 compliance or when inventory of the primary part is constrained. Both parts carry active product status and equivalent inventory availability.

Mercury United Electronics 628-025-220-042 (Similar Alternative): This part provides functional equivalence as a 25-position D-Sub receptacle with female sockets, through-hole solder termination, and identical shell size and connector layout. However, detailed electrical and mechanical specifications including current rating, voltage rating, operating temperature range, contact finish, contact material, dielectric material, flange feature, and material flammability rating are not provided in the available data. The 628-025-220-042 is designated as a metal series variant, which may indicate construction differences from the polyester dielectric AMPLIMITE HD-20 series. This part is suitable for applications where complete specification alignment cannot be verified or where alternative manufacturer sourcing is required.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5745058-3 be used as a direct replacement for the 745058-3?

A: Yes. The 5745058-3 is a direct equivalent with identical connector style, type, position count, shell size, mounting method, termination, current rating, voltage rating, operating temperature range, contact materials, and dielectric properties. The primary difference is RoHS3 compliance status. Both parts are from TE Connectivity AMP Connectors within the AMPLIMITE HD-20 series and are electrically and mechanically interchangeable.

Q: What are the key differences between the 745058-3 and the Mercury 628-025-220-042?

A: Both connectors share the same D-Sub receptacle configuration with 25 positions, 2 rows, shell size 3 (DB, B), through-hole mounting, and solder termination. The Mercury part originates from a different manufacturer and is part of the 628 (Metal) series. Detailed specifications for the Mercury part including current rating, voltage rating, operating temperature range, contact finish, contact material, and dielectric material are not provided in available documentation. Verification of complete specification alignment is required before substitution.

Q: Is the 745058-3 RoHS compliant?

A: No. The 745058-3 is RoHS non-compliant. If RoHS compliance is required, the TE Connectivity 5745058-3 is available as a ROHS3 compliant direct equivalent with identical electrical and mechanical specifications.

Q: What is the significance of the shell size designation "3 (DB, B)"?

A: Shell size 3 (DB, B) is the standard D-Sub shell size for 25-position connectors. This designation ensures mechanical compatibility with mating connectors and standard D-Sub mounting hardware. All listed substitute parts maintain this identical shell size specification.

Q: Can the Mercury 628-025-220-042 be used in applications requiring UL94 V-0 flammability rating?

A: The UL94 V-0 flammability rating for the Mercury 628-025-220-042 is not specified in available documentation. Confirmation of this specification is required before use in applications with flammability requirements.

Q: What is the difference between "Flash" gold contact finish and standard gold plating?

A: Flash gold finish refers to a thin electroplated gold layer applied to the contact surface. This specification is identical across the 745058-3 and 5745058-3. The Mercury part's contact finish specification is not provided.

Q: Are all three parts suitable for the same operating temperature range?

A: The 745058-3 and 5745058-3 both operate across -55°C to 105°C. The operating temperature range for the Mercury 628-025-220-042 is not specified in available data and must be verified independently.

Q: What packaging format is used for these connectors?

A: The 745058-3 and 5745058-3 are supplied in tube packaging. Packaging information for the Mercury 628-025-220-042 is not specified in available documentation.
