Parameter Comparison

Engineering Selection Recommendations

The EB63-S1R0660W is the direct substitute for the EB61-S1R0660W. Both connectors maintain identical electrical and mechanical specifications across all critical parameters that determine functional compatibility. The EB63-S1R0660W is the preferred selection due to its active product status, ensuring ongoing availability and supply chain continuity. Both parts carry identical RoHS non-compliance status and moisture sensitivity ratings. The difference in insulation material composition and connector color does not affect electrical performance or mechanical fit within the specified card thickness tolerance range.

Frequently Asked Questions (FAQ)

Q: Can the EB63-S1R0660W be used as a direct replacement for the EB61-S1R0660W?

A: Yes. Both connectors share identical electrical and mechanical specifications, including position count, pitch spacing, card thickness tolerance, contact material, contact finish, mounting configuration, and operating temperature range. The connectors are mechanically and electrically interchangeable.

Q: What is the difference between the EB61-S1R0660W and EB63-S1R0660W?

A: The primary differences are insulation material (DAP versus Polyester Thermoplastic, Glass Filled), connector color (green versus black), and product status (obsolete versus active). These differences do not affect functional compatibility or performance within the specified operating parameters.

Q: Why is the EB61-S1R0660W classified as obsolete?

A: The EB61-S1R0660W is no longer in active production. The EB63-S1R0660W serves as the active equivalent within the Vishay Dale EB6 series.

Q: Are there any compatibility concerns with the insulation material difference?

A: No. Both insulation materials meet the specified operating temperature range of -65°C ~ 125°C and moisture sensitivity level 1 (Unlimited). The material difference does not affect connector performance or compatibility with standard PCB applications.

Q: Does the color difference affect connector function?

A: No. Connector color is a cosmetic attribute and does not affect electrical performance, mechanical fit, or signal integrity.

Q: What is the card thickness tolerance for these connectors?

A: Both connectors accept cards with thickness between 0.054" and 0.071" (1.37mm to 1.80mm).

Q: Are both parts RoHS compliant?

A: No. Both the EB61-S1R0660W and EB63-S1R0660W are RoHS non-compliant.
