Key Parameters

Substitute Part Grouping Explanation

The ESQ-110-24-S-S qualifies as a direct substitute for the ESQ-110-49-S-S based on identical electrical and mechanical parameters. Both connectors share the same core specifications: 10-position configuration, 0.100" (2.54mm) pitch, elevated socket connector type with forked contacts, through-hole solder termination, and push-pull fastening. Electrical ratings, contact materials, finishes, and operating temperature ranges are identical across both parts. The substitution is valid based on these matching parameters: connector type, position count, pitch, mounting method, contact configuration, current and voltage ratings, insulation material, and compliance certifications. The primary difference is packaging format, with ESQ-110-24-S-S supplied in tube packaging versus the standard packaging of ESQ-110-49-S-S.

Parameter Comparison

Engineering Selection Recommendations

Both ESQ-110-49-S-S and ESQ-110-24-S-S are Active products with full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on packaging requirements and inventory availability. The ESQ-110-24-S-S offers tube packaging, which may be preferred for automated assembly processes or specific handling requirements. Both connectors meet identical electrical specifications, mechanical dimensions, and regulatory certifications. The choice between these parts does not impact circuit performance, thermal management, or compliance requirements.
