Key Parameters

Substitute Part Grouping Explanation

The ESW-126-48-L-D qualifies as a substitute for the ESW-126-23-L-D based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Connector Type: Elevated Socket (identical)
• Number of Positions: 52 (identical)
• Pitch - Mating: 0.100" (2.54mm) (identical)
• Number of Rows: 2 (identical)
• Row Spacing - Mating: 0.100" (2.54mm) (identical)
• Mounting Type: Through Hole (identical)
• Termination: Solder (identical)
• Contact Finish - Mating: Gold (identical)
• Current Rating: 5.2A per Contact (identical)
• Voltage Rating: 550VAC (identical)
• Operating Temperature: -55°C ~ 125°C (identical)
• Material Flammability Rating: UL94 V-0 (identical)
• RoHS Status: ROHS3 Compliant (identical)

Both parts belong to the ESW series base product family and maintain identical contact geometry, insulation material (Liquid Crystal Polymer), and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the ESW-126-23-L-D and ESW-126-48-L-D maintain Active product status with identical compliance certifications. Selection between these parts should be based on inventory availability and procurement lead times. The ESW-126-23-L-D currently maintains 1091 pieces in stock, while the ESW-126-48-L-D maintains 700 pieces. Both parts satisfy ROHS3 compliance requirements and UL94 V-0 flammability standards, making either suitable for applications requiring regulatory adherence. No electrical or mechanical performance differentiation exists between these parts.

Frequently Asked Questions (FAQ)

Q: Can the ESW-126-48-L-D directly replace the ESW-126-23-L-D in existing designs?

A: Yes. Both connectors share identical electrical specifications (5.2A per contact, 550VAC rating), mechanical dimensions (52 positions, 0.100" pitch, 2-row configuration), mounting method (through-hole solder termination), and operating temperature range (-55°C to 125°C). No design modifications are required.

Q: Are there differences in contact plating or material composition?

A: No. Both parts feature gold-plated mating contacts (10.0µin thickness), tin-plated posts, phosphor bronze contact material, and liquid crystal polymer insulation. Contact geometry and finish specifications are identical.

Q: What is the significance of the part number suffix difference between -23-L-D and -48-L-D?

A: The suffix variation indicates different manufacturing batches or production runs within the ESW-126 base product family. The electrical and mechanical specifications remain unchanged across these variants.

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both the ESW-126-23-L-D and ESW-126-48-L-D are ROHS3 compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Are there any packaging or inventory considerations for substitution?

A: Both parts are supplied in bulk packaging. The ESW-126-23-L-D has higher current inventory (1091 pieces), while the ESW-126-48-L-D has 700 pieces available. Selection may depend on procurement requirements and delivery schedules.
