ESW-126-58-G-D Equivalent & Substitute Parts

Part Overview

The ESW-126-58-G-D is a 52-position elevated socket connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This through-hole solder-terminated connector features gold-plated forked contacts and is rated for 5.2A per contact at 550VAC. The product is currently active and ROHS3 compliant, making it suitable for industrial and commercial electronic assemblies requiring reliable interconnection in temperature ranges from -55°C to 125°C.

Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The ESW-126-33-G-D qualifies as a direct substitute for the ESW-126-58-G-D based on identical electrical and mechanical parameters. Both connectors share the same series designation (ESW), connector type (elevated socket), contact configuration (52 positions, 2 rows), pitch spacing (0.100"), mounting method (through hole), termination type (solder), contact material and finish specifications, current and voltage ratings, operating temperature range, and compliance certifications.

The substitution is valid across all critical parameters that determine functional compatibility: mating pitch, row spacing, contact count, electrical ratings, environmental specifications, and material certifications. Both parts are manufactured by Samtec Inc. and maintain identical mechanical envelope and PCB footprint requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ESW-126-58-G-D and ESW-126-33-G-D are active products with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on availability and lead time requirements. The ESW-126-33-G-D currently maintains higher inventory (997 pcs) compared to the ESW-126-58-G-D (715 pcs), making it suitable for applications where supply chain continuity is a priority. Both connectors meet UL94 V-0 flammability requirements and are suitable for industrial temperature ranges. No performance degradation or functional limitation occurs when substituting one part for the other.

Frequently Asked Questions (FAQ)

Q: Are ESW-126-58-G-D and ESW-126-33-G-D mechanically interchangeable?

A: Yes. Both connectors share identical pitch spacing (0.100"), row configuration (2 rows), position count (52), and through-hole mounting requirements. PCB footprints are identical, and no layout modifications are required for substitution.

Q: Do these connectors have the same electrical ratings?

A: Yes. Both parts are rated for 5.2A per contact at 550VAC and operate across the same temperature range (-55°C to 125°C). Contact material, finish specifications, and current-carrying capacity are identical.

Q: What is the difference between ESW-126-58-G-D and ESW-126-33-G-D?

A: The parts are functionally equivalent. The difference in part number suffix (58 vs. 33) reflects internal Samtec manufacturing or packaging designations but does not indicate electrical or mechanical differences. All critical parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the ESW-126-58-G-D and ESW-126-33-G-D are ROHS3 compliant and meet UL94 V-0 flammability requirements.

Q: Can I use ESW-126-33-G-D as a direct replacement in existing designs?

A: Yes. No design changes, PCB modifications, or firmware updates are required. The connector is a direct mechanical and electrical substitute with identical mating interface and electrical performance.
