Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S0K2240X is determined by strict alignment of the following critical parameters:

Position Count & Pitch: 44 positions at 0.100" (2.54mm) spacing
Connector Type: Dual edge, female gender
Card Accommodation: 0.054" to 0.071" (1.37mm to 1.80mm) card thickness
Electrical Interface: Wire wrap termination with phosphor bronze gold-plated contacts
Environmental Range: -65°C to 125°C operating temperature
Mechanical Configuration: Through hole mounting, top mount opening with 0.125" (3.18mm) unthreaded flange

The EB43-S0K2240X qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while differing only in insulation material composition and color designation. Both parts share the same series designation (EB4), contact architecture, and functional performance envelope.

Engineering Selection Recommendations

The EB43-S0K2240X is the appropriate substitute for the obsolete EB41-S0K2240X. Both connectors maintain identical electrical performance, mechanical compatibility, and environmental specifications. The EB43-S0K2240X carries active product status, ensuring continued availability and supply chain support.

The primary differences are insulation material composition (Diallyl Phthalate versus Polyester Thermoplastic) and color designation (Green versus Black). Both materials are glass-filled and provide equivalent functional performance within the specified operating temperature range. Neither part achieves RoHS compliance, and both maintain MSL 1 classification with unlimited moisture sensitivity tolerance.

Selection of the EB43-S0K2240X eliminates obsolescence risk while preserving full functional and mechanical interchangeability with existing designs utilizing the EB41-S0K2240X.

Frequently Asked Questions (FAQ)

Q: Are the EB41-S0K2240X and EB43-S0K2240X mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 44-position configuration, 0.100" pitch, dual edge card accommodation (0.054" to 0.071" thickness), through hole mounting, and flange geometry. Physical installation and PCB layout compatibility are identical.

Q: What is the functional difference between the two insulation materials?

A: The EB41-S0K2240X uses Diallyl Phthalate (DAP) glass-filled insulation, while the EB43-S0K2240X uses Polyester Thermoplastic glass-filled insulation. Both materials maintain the same operating temperature range (-65°C to 125°C) and provide equivalent electrical isolation and mechanical support for the contact structure.

Q: Why is the EB41-S0K2240X classified as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The EB43-S0K2240X, carrying active product status, is the current production equivalent and recommended for new designs and ongoing procurement.

Q: Does the color difference (Green versus Black) affect electrical performance?

A: No. Color designation is a visual identifier only and does not impact electrical characteristics, contact performance, or environmental ratings. Selection between green and black variants is determined by design documentation or assembly requirements.

Q: Are both parts RoHS compliant?

A: No. Both the EB41-S0K2240X and EB43-S0K2240X are classified as RoHS non-compliant. If RoHS compliance is required, alternative connector families must be evaluated.

Q: What is the inventory status for substitution planning?

A: The EB41-S0K2240X has 718 pieces in stock (obsolete status). The EB43-S0K2240X has 1,063 pieces in stock (active status), providing superior supply chain availability for ongoing procurement requirements.
