3M 8250-7005 D-Sub 50 Position Plug Connector - Equivalent & Substitute Parts

Part Overview

The 3M 8250-7005 is a 50 position D-Sub plug connector with male pins, designed for panel mount applications using IDC (Insulation Displacement Contact) ribbon cable termination. This connector features a steel nickel-plated shell with gold-plated contacts and operates across the industrial temperature range of -55°C to 105°C.

The 8250-7005 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design compatibility, ensure supply chain continuity, and support legacy system maintenance where this connector type remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 8250-7005 is determined by the following critical parameters:

• Connector Style & Type: Must be D-Sub plug with male pins
• Position Count & Row Configuration: Must be 50 positions in 3-row layout
• Shell Size & Layout: Must be size 5 (DD, D)
• Termination Method: Must support IDC ribbon cable termination
• Contact Finish: Must be gold-plated
• Operating Temperature Range: Must support -55°C to 105°C minimum
• Flammability Rating: Must meet UL94 V-0
• RoHS Compliance: Must be RoHS compliant

The TE Connectivity AMP Connectors part number 1658607-1 meets all critical substitution parameters. While mounting type differs (free hanging vs. panel mount) and shell finish varies (tin vs. nickel), these differences do not prevent functional substitution in applications where the connector geometry, pin count, and electrical characteristics are the primary design constraints.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658607-1 is the primary substitute for the obsolete 3M 8250-7005. Selection is supported by the following factors:

Product Status: The 1658607-1 maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete 8250-7005.

Compliance & Certifications: Both connectors meet UL94 V-0 flammability requirements and RoHS compliance standards. The 1658607-1 carries ROHS3 certification, representing current regulatory alignment.

Electrical Compatibility: The 1658607-1 provides a higher current rating (1.25A vs. 1A), offering improved electrical margin. Both connectors support identical operating temperature ranges and contact finish specifications.

Mechanical Compatibility: Both connectors share identical D-Sub size 5 (DD, D) geometry, 50-position configuration, and IDC ribbon cable termination. The difference in mounting type (free hanging vs. panel mount) and shell finish (tin vs. nickel) does not affect pin-to-pin compatibility or signal integrity in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658607-1 directly replace the 3M 8250-7005 in existing designs?

A: Yes. Both connectors share identical D-Sub size 5 geometry, 50-position pin count, 3-row configuration, and IDC ribbon cable termination. Pin assignments and electrical characteristics are compatible. The difference in mounting type (free hanging vs. panel mount) requires mechanical design review for your specific application.

Q: What is the difference between panel mount and free hanging mounting types?

A: Panel mount connectors are designed for fixed installation through a panel with the shell secured to the panel structure. Free hanging (in-line) connectors are designed for cable-to-cable or cable-to-board connections without panel mounting. Your application's mechanical requirements determine which mounting type is appropriate.

Q: Are there any electrical performance differences between these connectors?

A: The 1658607-1 has a higher current rating (1.25A) compared to the 8250-7005 (1A). Both connectors support the same operating temperature range (-55°C to 105°C) and use gold-plated contacts. The higher current rating of the substitute provides additional electrical margin.

Q: What is the difference between nickel-plated and tin-plated shell finishes?

A: Nickel plating provides corrosion resistance and is commonly used in industrial environments. Tin plating offers similar corrosion protection with different surface characteristics. Both finishes are suitable for standard signal applications. Environmental exposure requirements may influence finish selection.

Q: Does the TE Connectivity 1658607-1 support the same ribbon cable specifications as the 3M 8250-7005?

A: Both connectors use IDC (Insulation Displacement Contact) termination for ribbon cable. Ribbon cable gauge and pitch specifications must match the connector's design. Consult the detailed connector specifications for your specific ribbon cable requirements.

Q: What is the inventory status of these connectors?

A: The 3M 8250-7005 has 934 pieces in stock but is classified as obsolete with no future production. The TE Connectivity 1658607-1 has 63,100 pieces in stock and maintains active production status, ensuring continued availability.
