EB72S-SA2240Y Equivalent & Substitute Parts

Part Overview

The EB72S-SA2240Y is a 44-position female card edge connector manufactured by Vishay Dale, designed for dual edge applications with 0.156" (3.96mm) pitch spacing. This connector features gold-plated phosphor bronze contacts with full bellows design and panel mount configuration using solder eyelet termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation

The Mercury United Electronics 306-022-500-102 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• 44-position configuration (22 positions per row)
• 0.156" (3.96mm) pitch spacing
• Dual edge card edge connector design
• Female gender
• Gold contact finish
• Panel mount configuration
• Solder eyelet termination
• Card thickness compatibility (0.054" ~ 0.070" overlaps with original 0.054" ~ 0.071")
• Unlimited moisture sensitivity level (MSL 1)

Parameter Variations:

• Contact material: Copper Alloy (substitute) vs. Phosphor Bronze (original)
• Contact type: Cantilever (substitute) vs. Full Bellows (original)
• Operating temperature: -40°C ~ 105°C (substitute) vs. -55°C ~ 125°C (original)
• Read out: Dual (substitute) vs. Single (original)
• Flange feature: Unthreaded 0.128" dia (substitute) vs. Threaded Insert 4-40 (original)
• RoHS status: ROHS3 Compliant (substitute) vs. Non-compliant (original)

Parameter Comparison

Engineering Selection Recommendations

The 306-022-500-102 serves as a direct functional substitute for the obsolete EB72S-SA2240Y in applications where the operating temperature range of -40°C ~ 105°C is acceptable. The substitute part offers improved regulatory compliance with ROHS3 certification, addressing modern environmental standards.

For applications requiring the full -55°C ~ 125°C temperature range of the original part, the reduced upper temperature limit of the substitute (105°C vs. 125°C) must be evaluated against actual system thermal requirements. The contact type difference (Cantilever vs. Full Bellows) and flange feature variation (Unthreaded vs. Threaded Insert) require mechanical fit verification in the target application.

The substitute part's active product status ensures ongoing availability and supply chain continuity compared to the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can the 306-022-500-102 directly replace the EB72S-SA2240Y in all applications?

A: The 306-022-500-102 is mechanically and electrically compatible for applications operating within -40°C ~ 105°C. Applications requiring the full -55°C ~ 125°C range require thermal analysis to confirm the substitute's adequacy. The flange feature difference (unthreaded vs. threaded insert) requires mechanical fit verification in the specific mounting configuration.

Q: What is the significance of the contact type difference (Cantilever vs. Full Bellows)?

A: Both contact types provide reliable electrical connection in card edge applications. Full Bellows contacts offer greater compliance and accommodation for card thickness variation, while Cantilever contacts provide a more compact design. The substitute's Cantilever design functions within the overlapping card thickness range (0.054" ~ 0.070").

Q: Does the substitute part meet current environmental compliance requirements?

A: Yes. The 306-022-500-102 is ROHS3 compliant, whereas the original EB72S-SA2240Y is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: Are there inventory considerations for this substitution?

A: The 306-022-500-102 is currently active with 865 pieces in stock, providing reliable supply availability. The original EB72S-SA2240Y is obsolete with 962 pieces remaining in inventory.

Q: What is the difference in Read Out configuration?

A: The original part features Single read out, while the substitute provides Dual read out. This difference does not affect functional compatibility in standard card edge connector applications.
