Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug with male pins)
• Number of positions (9)
• Shell size and layout (Size 1, DE/E configuration)
• Termination method (Solder cup)
• Current rating (3A)
• Voltage rating (250V)
• Operating temperature range (-55°C to 105°C)
• Shell material and finish (Steel, tin plated)
• Contact finish (Gold)
• Dielectric material (PBT, glass filled)

The substitute part 5-747904-2 maintains complete electrical and mechanical compatibility with the 747904-9 across all critical parameters. The primary differences are product status (active versus obsolete) and packaging configuration (tray versus unspecified).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-747904-2 is the direct equivalent for the obsolete 747904-9. Selection of the substitute part is based on the following engineering factors:

Product Status: The 747904-9 is classified as obsolete, making the active-status 5-747904-2 the appropriate choice for new procurement and ongoing applications.

Compliance and Certifications: Both parts carry identical electrical and mechanical specifications, including UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The 5-747904-2 carries ROHS3 compliance, which aligns with current regulatory requirements for electronic components in many markets.

Functional Equivalence: All critical parameters determining connector performance—pin count, shell size, termination method, current and voltage ratings, operating temperature range, and contact materials—are identical between the two parts.

Packaging Consideration: The 5-747904-2 is supplied in tray packaging, which is standard for production environments. The original 747904-9 packaging specification is not provided in available documentation.

The 5-747904-2 is suitable for direct substitution in all applications where the 747904-9 was originally specified.
