Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1445053-8 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (8)
• Number of rows (1)
• Pitch spacing (0.118" / 3.00mm)
• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation height (0.364" / 9.25mm)
• Contact shape (Square)

Material & Construction Parameters:

• Contact material (Brass)
• Insulation material (Polyamide/Nylon)
• Material flammability rating (UL94 V-0)
• Series designation (Micro MATE-N-LOK)

Substitute parts must maintain identical values across all listed parameters to ensure functional and mechanical interchangeability within the original application circuit and assembly process.

Parameter Comparison

Engineering Selection Recommendations

The 2-1445053-8 is a direct functional substitute for the obsolete 1445053-8 connector header. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch spacing, mounting method, and operating characteristics.

The primary distinction between these parts is product status and contact finish composition. The 1445053-8 is classified as obsolete, while the 2-1445053-8 maintains active product status with current manufacturing support. The 2-1445053-8 incorporates Tin contact finish (RoHS3 compliant) compared to the Tin-Lead finish of the original part, reflecting modern environmental compliance standards.

The 2-1445053-8 is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. Both parts share identical contact finish thickness specifications (100.0µin / 2.54µm) and maintain equivalent electrical performance across the full operating temperature range of -40°C to 105°C.

For applications requiring the 1445053-8, the 2-1445053-8 provides direct substitution with enhanced supply chain availability and compliance with current regulatory requirements.
