Substitute Part Grouping Explanation

Substitution eligibility for the ESW-125-38-G-D is determined by strict equivalence across the following critical parameters:

• Connector Type: Elevated Socket
• Number of Positions: 50
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 5.2A per Contact
• Voltage Rating: 550VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Phosphor Bronze
• RoHS Status: ROHS3 Compliant

The ESW-125-13-G-D meets all substitution criteria as a direct equivalent within the ESW-125 series, maintaining identical electrical performance, mechanical dimensions, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ESW-125-38-G-D and ESW-125-13-G-D are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on availability and inventory status. The ESW-125-38-G-D currently maintains 950 units in stock, while the ESW-125-13-G-D has 913 units available. Both parts are functionally equivalent for board-to-board connector applications requiring 50-position, 0.100" pitch elevated socket configurations with gold-plated contacts and solder termination.

Frequently Asked Questions (FAQ)

Q: Are ESW-125-38-G-D and ESW-125-13-G-D electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 5.2A per contact current rating, 550VAC voltage rating, and gold-plated contact finishes with equivalent thickness specifications.

Q: Do these connectors have the same mechanical footprint?

A: Yes. Both connectors share identical mechanical parameters: 50 positions, 0.100" (2.54mm) mating pitch, 2-row configuration with 0.100" row spacing, 0.435" insulation height, and 0.290" contact post length.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the ESW-125-38-G-D and ESW-125-13-G-D operate across -55°C to 125°C.

Q: What is the difference between these two part numbers?

A: The parts are functionally equivalent within the ESW-125 series. Differences in the part number suffix (38-G-D versus 13-G-D) reflect internal Samtec product line designations but do not affect electrical or mechanical performance for board-to-board connector applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the ESW-125-38-G-D and ESW-125-13-G-D are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: Can I use these connectors in high-current applications?

A: Yes. Both connectors are rated for 5.2A per contact, suitable for applications requiring moderate to high current distribution across multiple contact positions.
