Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 223978 is based on strict equivalence of the following critical parameters:

• Number of Positions: 110 positions (exact match required)
• Pitch Specification: 0.079" (2.00mm) center-to-center spacing
• Termination Method: Press-Fit technology
• Connector Type: Header with male pins
• Mounting Configuration: Through-hole mounting
• Connector Usage: Backplane application

The substitute part 3-5100143-0 from TE Connectivity AMP Connectors satisfies all these criteria. Both connectors are manufactured by TE Connectivity entities and share identical electrical and mechanical interface specifications. The substitute part is currently in Active production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison
