EB73D-SK0640X Equivalent & Substitute Parts

Part Overview

The EB73D-SK0640X is a 12-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 functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EB73D-SK0640X is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: 12-position female card edge connector with dual-edge, dual-row configuration
• Electrical Interface: 0.156" (3.96mm) pitch spacing for contact alignment
• Physical Compatibility: Card thickness accommodation and flange mounting geometry
• Contact Specifications: Phosphor bronze material with gold plating and full bellows contact type
• Termination Method: Through-hole solder termination
• Environmental Rating: Operating temperature range and moisture sensitivity classification

The GSM06DRKH from Sullins Connector Solutions meets these substitution criteria as an active product with equivalent electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The GSM06DRKH is the qualified substitute for the EB73D-SK0640X based on the following engineering criteria:

Functional Equivalence: Both connectors share identical electrical and mechanical specifications for 12-position, dual-edge, female card edge applications with 0.156" pitch spacing, phosphor bronze gold-plated contacts, and full bellows contact geometry.

Product Status: The EB73D-SK0640X is obsolete, while GSM06DRKH is an active product with current manufacturing support and documented availability.

Compliance Advantage: GSM06DRKH is ROHS3 compliant, addressing regulatory requirements for new designs and procurement cycles. Both parts are REACH unaffected and classified under identical HTSUS and ECCN codes.

Environmental Performance: GSM06DRKH extends the low-temperature operating range to -65°C, providing enhanced thermal margin for applications requiring extended environmental performance.

Mechanical Compatibility: Card thickness accommodation is compatible within standard tolerance ranges. Flange geometry differences (0.128" vs. 0.125" diameter) are within acceptable mechanical variation for through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can GSM06DRKH directly replace EB73D-SK0640X in existing designs?

A: Yes. Both connectors are functionally equivalent for 12-position dual-edge card edge applications with 0.156" pitch spacing. Electrical and mechanical interfaces are identical. Physical board layout and mounting hole patterns are compatible.

Q: What is the significance of the card thickness specification difference?

A: The EB73D-SK0640X accommodates cards from 0.054" to 0.071" (1.37mm to 1.80mm). The GSM06DRKH is specified for 0.062" (1.57mm) nominal thickness, which falls within the EB73D-SK0640X range. This represents the typical design point for dual-edge card connectors and does not restrict compatibility.

Q: Does the extended temperature range of GSM06DRKH affect compatibility?

A: No. The GSM06DRKH operating range of -65°C to 125°C encompasses the EB73D-SK0640X range of -55°C to 125°C. Extended low-temperature capability provides additional margin for demanding applications without affecting electrical or mechanical performance in standard operating conditions.

Q: What is the impact of RoHS3 compliance on substitution?

A: RoHS3 compliance of GSM06DRKH is advantageous for new designs and procurement. The EB73D-SK0640X is non-compliant due to its obsolete status. For legacy system support, both parts remain functionally equivalent. For new designs, GSM06DRKH is the preferred selection to meet current regulatory requirements.

Q: Are there packaging differences between these connectors?

A: The EB73D-SK0640X packaging is not specified. GSM06DRKH is supplied in tray packaging. Packaging format does not affect electrical or mechanical performance and is determined by procurement and assembly requirements.

Q: What is the contact finish thickness specification for GSM06DRKH?

A: GSM06DRKH specifies 10.0µin (0.25µm) gold contact finish thickness. The EB73D-SK0640X does not provide finish thickness specification. Both parts use gold plating on phosphor bronze contacts, meeting standard contact durability and conductivity requirements for card edge connector applications.
