Key Parameters

Substitute Part Grouping Explanation

Substitution of the 176381-1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Number of Positions: 40
• Pitch: 0.050" (1.27mm)
• Number of Rows: 2
• Contact Finish: Gold
• Contact Finish Thickness: 11.8µin (0.30µm)

Mechanical Parameters:

• Connector Type: Plug, Center Strip Contacts
• Mounting Type: Through Hole, Right Angle
• Height Above Board: 0.335" (8.50mm)
• Features: Board Lock
• Series: Free Height (FH)

Environmental Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part 5176381-1 maintains complete equivalence across all electrical, mechanical, and environmental parameters. The primary distinction between the main part and substitute is product status (obsolete versus active) and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The 176381-1 is classified as obsolete. The substitute part 5176381-1 provides functional equivalence with identical electrical, mechanical, and environmental specifications. Selection of 5176381-1 is appropriate for applications requiring continued supply of 40 position, 0.050" pitch rectangular connectors with right angle through hole mounting and gold plating.

For RoHS Compliance Requirements:

Applications subject to RoHS3 compliance mandates must utilize 5176381-1, which carries ROHS3 compliant certification. The original 176381-1 is RoHS non-compliant and does not satisfy regulatory requirements in jurisdictions enforcing RoHS directives.

For Active Production:

The 5176381-1 maintains active product status with current inventory availability (808 pieces in stock). The 176381-1, classified as obsolete, presents supply chain risk for new production allocations.

Packaging Consideration:

The 5176381-1 is supplied in bulk packaging. Procurement specifications should account for packaging format differences between the original part and substitute.
