EB73D-SK2240X Equivalent & Substitute Parts

Part Overview

The EB73D-SK2240X is a 44-position female card edge connector manufactured by Vishay Dale, designed for dual-edge applications with 0.156" (3.96mm) pitch spacing. This connector features gold-plated phosphor bronze contacts, through-hole solder termination, and operates across -55°C to 125°C. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB73D-SK2240X is determined by the following critical parameters:

• Position Count & Pitch: 44 positions at 0.156" (3.96mm) spacing
• Connector Type: Female, dual-edge card edge configuration
• Contact System: Phosphor bronze with gold plating, full bellows contact type
• Termination Method: Through-hole solder attachment
• Mechanical Compatibility: Card thickness acceptance range and flange mounting geometry
• Electrical Performance: Operating temperature range and contact material properties

The substitute part GSM22DRKH from Sullins Connector Solutions meets these core substitution criteria. Both connectors share identical position counts, pitch spacing, gender, dual-edge configuration, contact material composition, and solder termination methodology. Mechanical compatibility is maintained within acceptable card thickness tolerances.

Engineering Selection Recommendations

The GSM22DRKH from Sullins Connector Solutions is the designated manufacturer-recommended substitute for the obsolete EB73D-SK2240X. Selection of this substitute is supported by the following factors:

Product Status: The EB73D-SK2240X is obsolete and no longer manufactured. The GSM22DRKH maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The GSM22DRKH achieves ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing. Both parts maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

Functional Equivalence: Electrical and mechanical parameters are equivalent across all critical substitution criteria: position count, pitch spacing, contact system, termination method, and operating temperature performance.

Inventory Availability: The GSM22DRKH is available in active stock (778 Pcs) in tray packaging, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can GSM22DRKH directly replace EB73D-SK2240X in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications for the critical parameters that determine substitution eligibility: 44 positions, 0.156" pitch, female dual-edge configuration, phosphor bronze gold-plated contacts, and through-hole solder termination. The GSM22DRKH card thickness specification of 0.062" falls within the EB73D-SK2240X acceptance range of 0.054" to 0.071".

Q: What is the difference in operating temperature range?

A: The EB73D-SK2240X operates from -55°C to 125°C. The GSM22DRKH extends the lower temperature limit to -65°C, providing a wider operating envelope. Both maintain the same upper temperature limit of 125°C. This difference does not restrict substitution; the GSM22DRKH is suitable for all applications within the original part's temperature specification.

Q: Does the RoHS compliance difference affect substitution?

A: The EB73D-SK2240X is RoHS non-compliant, while GSM22DRKH achieves ROHS3 compliance. For new designs and manufacturing environments subject to RoHS regulations, the GSM22DRKH is the appropriate selection. For legacy system maintenance where RoHS compliance is not required, both parts remain functionally equivalent.

Q: Are there packaging differences between the two parts?

A: The EB73D-SK2240X packaging is not specified in the available data. The GSM22DRKH is supplied in tray packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: What is the contact finish thickness specification for each part?

A: The EB73D-SK2240X contact finish thickness is not specified. The GSM22DRKH specifies 10.0µin (0.25µm) gold plating thickness. Both parts use gold-plated phosphor bronze contacts suitable for equivalent electrical performance.

Q: Are there any flange or mounting geometry differences?

A: Minor differences exist in flange specifications. The EB73D-SK2240X features a flush mount, top opening, unthreaded flange with 0.128" (3.25mm) diameter. The GSM22DRKH specifies top mount opening, unthreaded flange with 0.125" (3.18mm) diameter. These dimensional variations are within typical manufacturing tolerances for this connector category and do not restrict mechanical compatibility in standard PCB mounting applications.
