EB72D-SE0660X Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The EB72D-SE0660X is a 12-position female card edge connector manufactured by Vishay Dale, designed for dual-edge board mounting applications with 0.156" (3.96mm) pitch spacing. This connector features gold-plated phosphor bronze contacts with full bellows design 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 procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB72D-SE0660X is determined by the following critical parameters:

• Connector Configuration: 12-position, dual-row, female card edge connector
• Pitch Specification: 0.156" (3.96mm) center-to-center spacing
• Contact System: Phosphor bronze with gold plating and full bellows contact type
• Mounting Method: Board edge, straddle mount configuration
• Termination Style: Solder eyelet(s)
• Environmental Range: Operating temperature compatibility

The GMM06DSEH-S13 meets these core substitution criteria. Variations in card thickness tolerance, flange dimensions, and product status do not preclude functional equivalence when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The GMM06DSEH-S13 serves as a direct functional equivalent to the EB72D-SE0660X for applications requiring 12-position, dual-row card edge connectors with 0.156" pitch spacing. Key selection factors include:

Product Status: The EB72D-SE0660X is obsolete, whereas the GMM06DSEH-S13 maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance Profile: The GMM06DSEH-S13 is ROHS3 compliant, addressing regulatory requirements for new designs and procurement cycles. The EB72D-SE0660X is RoHS non-compliant.

Environmental Performance: The GMM06DSEH-S13 extends the lower operating temperature limit to -65°C compared to -55°C for the original part, providing enhanced thermal margin in cold-environment applications.

Card Thickness Accommodation: The GMM06DSEH-S13 is specified for 0.062" (1.57mm) card thickness, which falls within the EB72D-SE0660X tolerance range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm), ensuring mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the GMM06DSEH-S13 directly replace the EB72D-SE0660X in existing designs?

A: Yes. Both connectors share identical pitch (0.156"), position count (12), configuration (dual female), contact material (phosphor bronze with gold plating), and mounting method (board edge, straddle mount). The GMM06DSEH-S13 card thickness specification of 0.062" falls within the EB72D-SE0660X tolerance band.

Q: What are the key differences between these two connectors?

A: Primary differences include product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), operating temperature lower limit (-55°C vs. -65°C), and packaging format (unspecified vs. tray). These differences do not affect electrical or mechanical substitution capability.

Q: Are there any card thickness compatibility concerns?

A: No. The GMM06DSEH-S13 is rated for 0.062" (1.57mm) card thickness, which is centered within the EB72D-SE0660X range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm). Standard card edge connector design accommodates this variation through bellows contact compliance.

Q: Does the gold plating thickness difference affect performance?

A: The GMM06DSEH-S13 specifies 30.0µin (0.76µm) gold plating thickness, whereas the EB72D-SE0660X does not specify this parameter. Both employ gold contact finish on phosphor bronze substrates, meeting standard electrical contact requirements for this connector class.

Q: What is the impact of the extended temperature range on the GMM06DSEH-S13?

A: The GMM06DSEH-S13 operates from -65°C to 125°C, compared to -55°C to 125°C for the EB72D-SE0660X. This extended lower temperature capability provides additional thermal margin and may be advantageous in cold-environment applications, though it does not restrict use in applications within the original temperature range.
