Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB61-S0K306FS is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: 60 positions, female gender, 0.125" (3.18mm) pitch, dual edge configuration, wire wrap termination
• Mechanical Compatibility: Card thickness acceptance range 0.054" ~ 0.071" (1.37mm ~ 1.80mm), through hole mounting, cantilever contact type
• Material & Environmental: Phosphor bronze contacts with gold finish, operating temperature range -65°C ~ 125°C

The substitute part EB63-S0K306FS meets all electrical and mechanical requirements. Variations in insulation material and color do not affect functional compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The EB63-S0K306FS is the direct functional equivalent to the EB61-S0K306FS. Both connectors share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: EB61-S0K306FS is obsolete while EB63-S0K306FS is active, ensuring continued availability and supply chain reliability.

Secondary differences in insulation material (DAP versus polyester thermoplastic, glass filled) and connector color (green versus black) do not impact electrical performance or mechanical compatibility within the specified operating envelope. Both parts maintain equivalent RoHS non-compliance status.

For new designs or system refreshes, EB63-S0K306FS is the appropriate selection due to active product status and assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Can EB63-S0K306FS directly replace EB61-S0K306FS in existing applications?

A: Yes. Both connectors are electrically and mechanically equivalent across all functional parameters: 60 positions, female gender, 0.125" pitch, dual edge configuration, wire wrap termination, and identical operating temperature range. Physical form factor and contact engagement are identical.

Q: Does the color difference (green vs. black) affect compatibility?

A: No. Color is a cosmetic attribute and does not affect electrical performance, mechanical fit, or environmental operation.

Q: What is the significance of the different insulation materials?

A: Both insulation materials (DAP and polyester thermoplastic, glass filled) are suitable for the specified operating temperature range and environmental conditions. The material difference does not impact connector function or compatibility.

Q: Why is EB61-S0K306FS listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. EB63-S0K306FS provides equivalent functionality with active product status, ensuring supply availability.

Q: Are there any compliance differences between the two parts?

A: Both parts share identical RoHS non-compliance status and equivalent ECCN/HTSUS classifications. No compliance advantage exists between the two options.

Q: What card thickness range is supported?

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