DBF25S064TLF D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The DBF25S064TLF is a 25-position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) with female sockets for vertical solder termination. This connector is part of the D-series product line and is currently in stock with 851 units available. D-Sub connectors of this configuration are essential for applications requiring standardized parallel data transmission, legacy system interfaces, and industrial control connections where 25-position female receptacle configurations are specified.

Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain optimization is required, or when design flexibility allows for equivalent alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-747913-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) qualifies as an equivalent alternative based on the following critical parameters that determine substitution compatibility:

Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size / Connector Layout: 3 (DB, B)
• Mounting Type: Free Hanging (In-Line)
• Termination Method: Solder Cup
• Voltage Rating: 250V
• Current Rating: 3A
• Operating Temperature Range: -55°C ~ 105°C
• Shell Material / Finish: Steel, Tin Plated
• Contact Material: Brass
• Contact Finish: Gold
• Dielectric Material: Polybutylene Terephthalate (PBT), Glass Filled
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

These parameters define the functional and mechanical equivalence required for direct substitution in applications where the DBF25S064TLF is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the DBF25S064TLF and 5-747913-2 meet identical electrical and mechanical specifications for 25-position D-Sub receptacle applications. Selection between these parts should be based on the following factors:

Primary Part (DBF25S064TLF): Use when Amphenol ICC supply chain is preferred or when design documentation specifically requires the D-series connector line.

Substitute Part (5-747913-2): Use when TE Connectivity AMPLIMITE HD-20 series availability is superior, when supply chain optimization favors TE Connectivity sourcing, or when inventory levels require immediate fulfillment. The substitute part carries Active product status and maintains higher stock levels (3299 units versus 851 units).

Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating equivalent reliability and storage requirements. The contact finish thickness specification (8.00µin) provided for the substitute part represents standard gold plating for D-Sub connectors and does not constitute a functional difference.

Frequently Asked Questions (FAQ)

Q: Can 5-747913-2 be used as a direct replacement for DBF25S064TLF in existing designs?

A: Yes. Both connectors share identical electrical ratings (250V, 3A), mechanical configuration (25-position, 2-row, DB shell size), termination method (solder cup), and material specifications (steel tin-plated shell, brass gold-plated contacts, PBT dielectric). They are functionally equivalent for applications requiring 25-position D-Sub female receptacles.

Q: Are there differences in packaging between these parts?

A: The DBF25S064TLF packaging is not specified in the available data. The 5-747913-2 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) ratings. Both operate across the identical temperature range (-55°C ~ 105°C) and support the same voltage and current specifications.

Q: What is the difference between the D-series and AMPLIMITE HD-20 series?

A: These are manufacturer-specific series designations. The D-series is Amphenol ICC's product line designation, while AMPLIMITE HD-20 is TE Connectivity's series name. Both series produce connectors with identical electrical and mechanical characteristics for this 25-position configuration.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain strategy, inventory availability, and manufacturer preference. Both parts meet identical specifications and are suitable for new designs. The 5-747913-2 currently has higher inventory availability (3299 units) and Active product status.
