Key Parameters

Substitute Part Grouping Explanation

The ESQ-105-48-S-S-LL qualifies ESQ-105-23-S-S-LL as a direct substitute based on the following critical parameters that determine functional equivalence:

• Number of Positions: Both parts are 5-position connectors
• Pitch - Mating: Both maintain 0.100" (2.54mm) spacing
• Connector Type: Both are elevated socket connectors
• Mounting Type: Both are through-hole mounted
• Current Rating: Both rated at 5.7A per contact
• Voltage Rating: Both rated at 550VAC
• Operating Temperature Range: Both operate from -55°C to 125°C
• Contact Finish - Mating: Both feature gold-plated mating contacts
• Insulation Material: Both use Liquid Crystal Polymer (LCP)
• Compliance: Both are RoHS3 compliant with UL94 V-0 flammability rating

These parameters define the electrical and mechanical compatibility envelope for this connector category. Substitution is valid when all critical parameters match.

Parameter Comparison

Engineering Selection Recommendations
