Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB61-S2R0660W is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Card edge dual-row female connector
• Position Count: 12 positions total (6 per row)
• Pitch Spacing: 0.125" (3.18mm)
• Card Thickness Acceptance: 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Mounting & Termination: Through-hole, right-angle, solder termination
• Contact Specifications: Phosphor bronze material with gold finish, cantilever contact type
• Electrical Performance: Operating temperature range -65°C ~ 125°C

The EB63-S2R0660W qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters. Differences in insulation material and RoHS compliance status do not affect functional interchangeability within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The EB63-S2R0660W is a direct functional equivalent to the EB61-S2R0660W. Both connectors maintain identical electrical and mechanical specifications, including contact configuration, pitch spacing, card thickness tolerance, and operating temperature range.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The EB61-S2R0660W is obsolete, while the EB63-S2R0660W is actively manufactured. The EB63-S2R0660W achieves ROHS3 compliance, whereas the EB61-S2R0660W does not. The insulation material differs (Polyester Thermoplastic, Glass Filled versus Diallyl Phthalate), but this change does not affect functional performance within the specified operating envelope.

For new designs and ongoing production requiring this connector type, the EB63-S2R0660W is the appropriate selection due to active availability and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the EB63-S2R0660W be used as a direct replacement for the EB61-S2R0660W?

A: Yes. Both connectors are electrically and mechanically equivalent. They share identical position count (12), pitch spacing (0.125"), card thickness tolerance (0.054" ~ 0.071"), contact material (phosphor bronze with gold finish), and operating temperature range (-65°C ~ 125°C). The EB63-S2R0660W is the active production equivalent.

Q: What is the difference in insulation material between these parts?

A: The EB61-S2R0660W uses Diallyl Phthalate (DAP) insulation, while the EB63-S2R0660W uses Polyester Thermoplastic, Glass Filled insulation. Both materials are suitable for the specified operating temperature range and do not affect connector functionality or compatibility.

Q: Why is the EB61-S2R0660W listed as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Vishay Dale. The EB63-S2R0660W represents the current production equivalent within the EB6 series.

Q: Are there any compatibility concerns when substituting the EB63-S2R0660W for the EB61-S2R0660W?

A: No compatibility concerns exist. Both connectors accept the same card thickness range and maintain identical electrical performance specifications. Physical form factor and mounting configuration are identical.

Q: Does RoHS compliance status affect interchangeability?

A: RoHS compliance status reflects regulatory requirements for the manufacturing process and material composition. It does not affect the electrical or mechanical performance of the connector itself. The EB63-S2R0660W's ROHS3 compliance may be required for certain applications or supply chain requirements.
