Both parts are suitable for applications requiring 2-position board-to-board elevated socket connectors with 0.100" pitch and 5.7A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can ESQ-102-34-L-S be used as a direct replacement for ESQ-102-59-L-S?

A: Yes. Both parts share identical electrical ratings (5.7A per contact, 550VAC), mechanical dimensions (0.100" pitch, 0.635" insulation height, 0.280" contact length), contact materials (Phosphor Bronze with gold mating finish), and operating temperature range (-55°C ~ 125°C). Both are UL94 V-0 rated and ROHS3 compliant.

Q: Are there any differences in the connector specifications between these two part numbers?

A: No. All provided electrical, mechanical, and material specifications are identical between ESQ-102-59-L-S and ESQ-102-34-L-S. Both are Samtec Inc. elevated socket connectors within the ESQ series.

Q: What determines substitution eligibility for ESQ-102 series connectors?

A: Substitution is valid when the following parameters remain constant: connector type (Elevated Socket), number of positions (2), pitch (0.100"), mounting method (Through Hole), contact finish (Gold), current rating (5.7A per contact), voltage rating (550VAC), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0).

Q: Are both parts suitable for the same PCB layout and footprint?

A: Yes. Both ESQ-102-59-L-S and ESQ-102-34-L-S have identical through-hole mounting specifications, insulation height (0.635"), and contact post length (0.280"), making them footprint-compatible on PCB designs.

Q: What is the current inventory status for these parts?

A: ESQ-102-59-L-S has 1140 pcs available, and ESQ-102-34-L-S has 877 pcs available, both listed as new original stock in bulk packaging.
