Mounting type (Free Hanging, In-Line)
Flange feature (Housing/Shell, Unthreaded)

Electrical Compatibility:

Termination type (IDC, Discrete Wire)
Voltage rating (250V)
Operating temperature range (-55°C ~ 105°C)
Wire gauge support (22-26 AWG)

Material & Environmental Specifications:

Shell material and finish (Steel, Tin Plated)

Engineering Selection Recommendations

The 1-745491-8 is the direct substitute for the obsolete 745491-5. Both connectors are manufactured by TE Connectivity and belong to the same AMPLIMITE HDE-20 series. All mechanical, electrical, and material specifications are identical.

The primary distinction between the two parts is product status and regulatory compliance:

745491-5 (Main Part):

Product status: Obsolete
RoHS status: Non-compliant
Limited availability (925 units in stock)

1-745491-8 (Substitute):

Product status: Active
RoHS status: Compliant
Significantly higher availability (140,300 units in stock)

For new designs, maintenance applications, and systems requiring RoHS compliance, the 1-745491-8 is the appropriate selection. The active product status and RoHS compliance of the 1-745491-8 ensure long-term supply chain viability and regulatory alignment.
