Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S2R304FS is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 60-position female card edge connector with dual edge read-out capability
• Pitch Specification: 0.100" (2.54mm) center-to-center spacing
• Mechanical Compatibility: Dual row configuration (2 rows × 30 positions per row) with card thickness acceptance range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Electrical & Contact Properties: Phosphor bronze contact material with gold finish, solder termination
• Mounting Configuration: Through-hole, right-angle orientation
• Environmental Performance: Operating temperature range of -65°C ~ 125°C

The EB43-S2R304FS meets all substitution criteria as a direct functional equivalent, with the primary distinction being material composition of the insulation housing and active product availability status.

Parameter Comparison

Engineering Selection Recommendations

The EB43-S2R304FS is a direct functional substitute for the obsolete EB41-S2R304FS. 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 differences are material composition of the insulation housing (DAP versus polyester thermoplastic) and connector color (green versus black). Both insulation materials are glass-filled and provide equivalent performance within the specified operating environment. The EB43-S2R304FS offers the advantage of active product status with confirmed inventory availability (966 pcs), ensuring supply chain continuity for replacement and new production requirements.

Both parts maintain identical RoHS non-compliance status and MSL rating, indicating no change in handling or environmental requirements during assembly and deployment.

Frequently Asked Questions (FAQ)

Q: Can the EB43-S2R304FS directly replace the EB41-S2R304FS in existing designs?

A: Yes. The EB43-S2R304FS is mechanically and electrically equivalent. All contact positions, pitch spacing, card thickness tolerance, mounting configuration, and termination method are identical. The connector will interface with existing card edge designs without modification.

Q: What is the difference between the insulation materials used in these connectors?

A: The EB41-S2R304FS uses Diallyl Phthalate (DAP) glass-filled insulation, while the EB43-S2R304FS uses polyester thermoplastic glass-filled insulation. Both materials provide equivalent electrical and mechanical performance within the specified operating temperature range of -65°C ~ 125°C.

Q: Does the color difference between green and black affect connector performance?

A: No. Color is a cosmetic distinction only and does not affect electrical performance, mechanical compatibility, or environmental ratings. Selection between green and black variants is based on design preference or inventory availability.

Q: Are there any compliance or certification differences between these parts?

A: Both connectors share identical RoHS non-compliance status and MSL rating of 1 (Unlimited). No change in handling procedures, storage requirements, or compliance documentation is required when substituting between these parts.

Q: What is the current availability status of each connector?

A: The EB41-S2R304FS is classified as obsolete with 661 pcs in stock. The EB43-S2R304FS is active with 966 pcs in stock, providing assured supply for ongoing production and replacement applications.
