Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1776489-3 is determined by strict alignment of core mechanical and electrical parameters. The following criteria establish substitution validity:

Mechanical Compatibility Requirements:

• Number of Positions: 3
• Pitch: 0.197" (5.00mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Unshrouded
• Contact Tail Length: 0.138" (3.50mm)
• Insulation Height: 0.079" (2.00mm)

Electrical Performance Requirements:

• Termination Style: Solder
• Mounting Type: Through Hole
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The Phoenix Contact 1933192 satisfies all mechanical compatibility requirements and maintains equivalent flammability and moisture sensitivity ratings. Both components feature identical pitch, position count, orientation, and physical dimensions, enabling direct substitution in through-hole solder applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1776489-3 and Phoenix Contact 1933192 maintain Active product status, ensuring continued availability and manufacturing support. The 1776489-3 carries RoHS Compliant certification, while the 1933192 carries ROHS3 Compliant certification, both meeting regulatory requirements for electronic component manufacturing.

The Phoenix Contact 1933192 provides higher electrical ratings under both IEC and UL standards. The 1933192 supports 12A at 400V (IEC) and 16A at 300V (UL), compared to the 1776489-3 which supports 10A at 250V (UL). Both components share identical mechanical dimensions and mounting characteristics, making the 1933192 suitable for applications requiring higher current or voltage capacity within the same form factor.

Selection between these components depends on application voltage and current requirements. For applications operating within 10A at 250V specifications, either component is functionally equivalent. For applications requiring higher electrical performance, the 1933192 is the appropriate selection.
