Substitute Part Grouping Explanation

Substitution of the 745494-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters:

Connector type (Plug, Male Pins)
Number of positions (15)
Number of rows (2)
Shell size and layout (2 DA, A)
Voltage rating (250V)
Contact material (Phosphor Bronze)
Contact finish (Gold)

Mechanical Parameters:

Mounting type (Free Hanging, In-Line)
Termination method (IDC, Discrete Wire)
Shell material and finish (Steel, Tin Plated)
Wire gauge compatibility (26-30 AWG)
Operating temperature range (-55°C ~ 105°C)

Compliance Parameters:

Flammability rating (UL94 V-0)
Dielectric material (Thermoplastic, Glass Filled)

The substitute part 1-745494-7 meets all these criteria and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The substitute part 1-745494-7 is a direct functional equivalent to the 745494-1 across all electrical and mechanical parameters. Both connectors are manufactured by TE Connectivity within the same AMPLIMITE HDE-20 series and share identical specifications for connector type, pin configuration, termination method, voltage rating, temperature range, and material composition.

The primary distinction between these parts is product status and regulatory compliance. The 745494-1 is obsolete and RoHS non-compliant, while the 1-745494-7 is an active product with ROHS3 compliance. For new designs or system upgrades, the 1-745494-7 is the appropriate selection. For legacy system maintenance where the original 745494-1 is no longer available, the 1-745494-7 provides identical electrical and mechanical performance.

Both parts carry the same ECCN (EAR99) and HTSUS classification, indicating equivalent export and tariff treatment.
