Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM53740-16 is based on the following critical parameters that must align for functional equivalence:

• Manufacturer Series: Combo D® (maintains connector family compatibility)
• Contact Type & Size: Male Pin, Size 8 (ensures mechanical fit within D-Sub shells)
• Coaxial Application: Type classification for RF/signal integrity
• Contact Finish: Gold plating (maintains electrical performance and corrosion resistance)
• Termination Method: The original part uses crimp termination for RG-180 wire; substitutes may employ alternative termination methods (solder, machined) provided they accommodate the same contact size and coaxial configuration

The substitute DM537405002 maintains the core functional parameters while transitioning from crimp to solder termination and from discrete RG-180 wire gauge to coaxial cable compatibility, representing an active-status alternative within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The DM537405002 is the active equivalent for the obsolete DM53740-16. Both components share identical manufacturer, series designation, contact type, contact size, and coaxial classification. The primary difference is termination method: the original uses crimp termination while the substitute employs solder termination with machined contact form.

Selection of DM537405002 is appropriate for applications where solder termination is compatible with assembly processes and cable specifications. The substitute maintains the same contact size (8) and gold finish, ensuring mechanical and electrical compatibility within Combo D® connector shells.

Both parts carry identical export classification (EAR99) and tariff codes (8536.90.4000), confirming regulatory equivalence. The substitute's active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can DM537405002 directly replace DM53740-16 in existing assemblies?

A: Mechanical compatibility is confirmed through identical contact size (8), contact type (male pin), and series designation (Combo D®). The primary consideration is termination method compatibility: DM537405002 uses solder termination versus the original's crimp termination. Assembly process and cable specifications must accommodate solder termination.

Q: What is the significance of the contact form difference (machined vs. standard)?

A: The substitute's machined contact form is a manufacturing specification that does not affect functional compatibility within the D-Sub connector shell. Both contact forms maintain the same electrical and mechanical interface requirements for size 8 male pins.

Q: Are there differences in wire gauge compatibility?

A: The original DM53740-16 specifies RG-180 wire gauge for crimp termination. The substitute DM537405002 is designed for coaxial cable with solder termination. Cable diameter and impedance specifications must be verified against application requirements to ensure proper termination and signal integrity.

Q: Does the gold finish thickness differ between parts?

A: The original specifies 50.0µin (1.27µm) gold finish thickness. The substitute's finish thickness is not specified in available documentation. Both parts confirm gold contact finish, meeting standard corrosion resistance and electrical conductivity requirements for coaxial D-Sub applications.

Q: What is the inventory status for these parts?

A: DM53740-16 (obsolete) has 856 pieces in stock. DM537405002 (active) has 1084 pieces in stock, providing greater long-term availability assurance.
