EB72S-SA0660W Equivalent & Substitute Parts

Part Overview

The EB72S-SA0660W 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, solder eyelet termination, and operates across a temperature range of -55°C to 125°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring this connector class.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EB72S-SA0660W is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Card edge connector
• Gender: Female
• Total positions: 12
• Pitch: 0.156" (3.96mm)
• Card configuration: Dual edge
• Number of rows: 2
• Contact finish: Gold
• Termination: Solder eyelet(s)
• Mounting type: Free hanging (in-line)

Allowable Variations:

• Card thickness tolerance: Substitute range 0.054" ~ 0.070" (1.37mm ~ 1.78mm) is compatible with original specification 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Contact material: Phosphor bronze (original) to copper alloy (substitute) both provide equivalent electrical performance in this application class
• Contact type: Full bellows (original) to cantilever (substitute) both accommodate the specified card thickness range
• Operating temperature: Substitute range -40°C ~ 105°C represents a narrower specification than the original -55°C ~ 125°C; applications requiring the full original temperature range require verification of actual operating conditions
• Read out configuration: Single (original) to dual (substitute) does not affect electrical compatibility

Parameter Comparison

Engineering Selection Recommendations

The 306-006-500-101 manufactured by Mercury United Electronics, Inc. is the designated substitute for the obsolete EB72S-SA0660W. Selection of this substitute is supported by the following engineering factors:

Functional Equivalence: The substitute part maintains all critical electrical and mechanical parameters required for direct replacement in dual-edge card edge connector applications with 12 positions at 0.156" pitch.

Compliance Status: The 306-006-500-101 holds ROHS3 compliance, whereas the original EB72S-SA0660W is RoHS non-compliant. For applications subject to RoHS regulations, the substitute provides regulatory alignment.

Product Availability: The original part is classified as obsolete with no ongoing manufacturing. The substitute is classified as active product with current manufacturing and documented inventory availability.

Temperature Range Consideration: The substitute operates across -40°C to 105°C, which is narrower than the original specification of -55°C to 125°C. Applications requiring operation at temperatures below -40°C or above 105°C require assessment of actual system operating conditions to determine if the substitute range is sufficient.

Contact Material and Type: Both phosphor bronze full bellows (original) and copper alloy cantilever (substitute) contacts are suitable for this connector class and card thickness range. Both configurations provide equivalent electrical performance and mechanical retention.

Frequently Asked Questions (FAQ)

Q: Can the 306-006-500-101 be used as a direct replacement for the EB72S-SA0660W?

A: Yes. The 306-006-500-101 is electrically and mechanically compatible for applications operating within the substitute's temperature range of -40°C to 105°C. Both connectors accommodate the same card thickness range, pitch, position count, and termination method.

Q: What is the difference between full bellows and cantilever contact types?

A: Both contact types are designed to accommodate the specified card thickness range of 0.054" to 0.070" (1.37mm to 1.78mm). Full bellows contacts use a spring-loaded design, while cantilever contacts use a cantilevered beam design. Both provide equivalent electrical contact and mechanical retention for this application.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 306-006-500-101 is ROHS3 compliant. The original EB72S-SA0660W is RoHS non-compliant. For applications subject to RoHS regulations, the substitute provides compliance.

Q: What is the significance of the operating temperature difference?

A: The original part operates from -55°C to 125°C, while the substitute operates from -40°C to 105°C. The substitute range is narrower. Applications requiring operation below -40°C or above 105°C must confirm that actual system operating conditions fall within the substitute's specified range.

Q: Are the contact finish specifications equivalent?

A: Both parts feature gold contact finish. The substitute specifies a finish thickness of 10.0µin (0.25µm), while the original does not specify thickness. Both gold finishes provide equivalent electrical performance for this connector class.

Q: What is the difference between single and dual read-out configurations?

A: Read-out configuration refers to the contact arrangement. Single read-out (original) and dual read-out (substitute) do not affect electrical compatibility or mechanical fit. Both configurations are suitable for this 12-position dual-edge connector application.

Q: Is the substitute part currently available?

A: Yes. The 306-006-500-101 is classified as active product with documented inventory of 709 pieces in stock.
