MDP-S-9 Equivalent & Substitute Parts

Part Overview

The MDP-S-9 is a double banana plug connector manufactured by Pomona Electronics, designed for solderless termination in standard banana connector applications. This stackable connector features a shorting bar and is rated for 50°C operating temperature. The part is Active status and RoHS3 compliant, making it suitable for modern electronic assembly requirements. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when operational requirements align with alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDP-S-9 are qualified based on the following critical parameters that determine functional equivalence:

• Connector Type: Double banana plug with male gender and standard banana diameter
• Termination Method: Solderless connection
• Insulation Configuration: Non-mating end insulated
• Contact Material and Finish: Beryllium copper with nickel plating
• Mounting Style: Free hanging (in-line) configuration
• Compliance: RoHS compliance status and REACH unaffected designation

The substitute part BU-PMDP-S-9 meets these core electrical and mechanical parameters, enabling direct functional substitution in applications where the MDP-S-9 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the MDP-S-9 and BU-PMDP-S-9 are Active status products with full RoHS and REACH compliance, qualifying them for use in regulated applications. The MDP-S-9 is RoHS3 compliant, while the BU-PMDP-S-9 carries RoHS compliance. Both parts maintain identical electrical and mechanical specifications for connector type, termination method, contact materials, and insulation configuration.

The BU-PMDP-S-9 provides an extended operating temperature range (-50°C ~ 105°C) compared to the MDP-S-9 (50°C), making it suitable for applications requiring broader thermal performance. Selection between these parts should be based on temperature requirements and availability constraints specific to the application environment.

Frequently Asked Questions (FAQ)

Q: Can the BU-PMDP-S-9 directly replace the MDP-S-9 in existing designs?

A: Yes. Both parts share identical connector type, gender, plug diameter, mounting configuration, termination method, insulation, contact material, and contact finish. The BU-PMDP-S-9 is functionally equivalent for standard applications.

Q: What is the difference between "Stackable" and "Shorting" designations?

A: Both designations refer to the connector's ability to accommodate multiple connections. The MDP-S-9 uses a shorting bar feature, while the BU-PMDP-S-9 uses a set screw mechanism. Both enable stacking functionality in double banana plug applications.

Q: Are there temperature limitations when substituting the BU-PMDP-S-9 for the MDP-S-9?

A: The MDP-S-9 is rated for 50°C operation. The BU-PMDP-S-9 supports -50°C ~ 105°C. When substituting, ensure the application's thermal environment does not exceed 50°C to maintain equivalence with the original specification.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and REACH unaffected. The MDP-S-9 carries RoHS3 certification, while the BU-PMDP-S-9 carries RoHS certification. Both meet modern regulatory requirements for electronic component use.

Q: What wire gauge is compatible with the BU-PMDP-S-9?

A: The BU-PMDP-S-9 specification does not specify wire gauge in the provided data. The MDP-S-9 is rated for 18 AWG. Consult manufacturer documentation for the BU-PMDP-S-9 wire gauge compatibility before final assembly.
