Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S2R224FS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 44
• Gender: Female
• Pitch: 0.100" (2.54mm)
• Card Thickness: 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Number of Rows: 2
• Read Out: Dual
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Termination: Solder

Allowable Variations:

• Mounting Type: Through Hole variants (including Right Angle configurations)
• Insulation Material: Alternative glass-filled thermoplastic compounds
• Color: Cosmetic variation only
• Product Status: Active status preferred for ongoing availability

The EB43-S2R224FS qualifies as a direct substitute based on identical electrical and mechanical specifications, with the primary differences being product status (Active vs. Obsolete), insulation material composition, color designation, and mounting configuration flexibility.

Parameter Comparison

Engineering Selection Recommendations

The EB43-S2R224FS is a direct functional equivalent to the EB41-S2R224FS. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, card thickness tolerance, contact material, and operating temperature range.

The primary advantage of the EB43-S2R224FS is its Active product status, ensuring long-term availability and supply chain continuity. The EB41-S2R224FS, classified as Obsolete, presents procurement risk for future applications and system revisions.

Both parts carry identical RoHS non-compliance status and MSL rating. The insulation material difference (DAP versus Polyester Thermoplastic) and color variation (Green versus Black) are secondary considerations that do not affect electrical or mechanical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the EB43-S2R224FS replace the EB41-S2R224FS in existing designs?

A: Yes. The EB43-S2R224FS maintains identical electrical and mechanical specifications. The connector accepts the same card thickness range, operates across the same temperature range, and provides equivalent contact performance through identical phosphor bronze gold-plated construction.

Q: What is the difference between the mounting types listed?

A: The EB41-S2R224FS specifies Through Hole mounting, while the EB43-S2R224FS offers both Through Hole and Right Angle configurations. Both support the same solder termination method and are compatible with standard PCB layouts designed for 0.100" pitch dual-edge connectors.

Q: Are there compatibility concerns with the different insulation materials?

A: No. Both Diallyl Phthalate (DAP) and Polyester Thermoplastic are glass-filled compounds meeting the same mechanical and thermal requirements for this connector class. The material difference does not affect electrical performance or operating temperature range.

Q: Does the color difference impact functionality?

A: No. Color is a cosmetic designation only and does not affect electrical or mechanical performance. Both Green and Black variants use identical contact materials and finishes.

Q: Why is product status important for this substitution?

A: The EB41-S2R224FS is Obsolete, indicating discontinued manufacturing and limited future availability. The EB43-S2R224FS is Active, ensuring continued supply and support for new designs and system revisions.
