EB72S-SA2260V Equivalent & Substitute Parts

Part Overview

The EB72S-SA2260V 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 solder eyelet termination for panel mount applications. The product is classified as obsolete, necessitating identification of active equivalent components to maintain system compatibility and ensure continued supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EB72S-SA2260V is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 44
• Gender: Female
• Pitch: 0.156" (3.96mm)
• Card Type: Dual Edge
• Termination: Solder Eyelet(s)
• Mounting Type: Panel Mount
• Contact Finish: Gold

Allowable Variations:

• Contact Material: Phosphor Bronze or Copper Alloy (both provide equivalent electrical conductivity and corrosion resistance)
• Contact Type: Full Bellows or Cantilever (both provide adequate contact pressure and retention)
• Card Thickness Tolerance: Overlapping ranges within 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Operating Temperature: Substitute range must encompass or exceed the original -55°C ~ 125°C specification
• Read Out Configuration: Single or Dual (functional difference does not affect core substitution compatibility)

The substitute part 306-022-500-104 (Mercury United Electronics, Inc.) meets all mandatory matching parameters and operates within acceptable tolerance variations.

Parameter Comparison

Engineering Selection Recommendations

The 306-022-500-104 (Mercury United Electronics, Inc.) is the qualified substitute for the obsolete EB72S-SA2260V. Selection is based on the following engineering criteria:

Product Status: The substitute is actively manufactured and in stock (834 pcs available), ensuring reliable supply chain continuity compared to the obsolete original part.

Electrical and Mechanical Compatibility: All critical parameters align: 44 positions, female gender, 0.156" pitch, dual-edge configuration, gold-plated contacts, and solder eyelet termination. Contact material variation (copper alloy vs. phosphor bronze) and contact type variation (cantilever vs. full bellows) are functionally equivalent for this connector class.

Compliance Status: The substitute meets ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The original part is RoHS non-compliant.

Operating Temperature Consideration: The substitute operating range (-40°C ~ 105°C) is narrower than the original (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C must be evaluated against actual system requirements before substitution.

Flange Feature Variation: The substitute flange diameter is 0.156" (3.96mm) compared to the original 0.142" (3.61mm). Verify mechanical fit within the panel mount application.

Frequently Asked Questions (FAQ)

Q: Can the 306-022-500-104 directly replace the EB72S-SA2260V in all applications?

A: The 306-022-500-104 is electrically and mechanically compatible for standard applications. However, verify two conditions: (1) operating temperature requirements do not exceed -40°C to 105°C range, and (2) the flange diameter difference (0.156" vs. 0.142") accommodates the panel mount opening.

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

A: Both contact types provide adequate contact pressure and retention force for card edge connectors at this pitch and position count. The cantilever design in the substitute is a standard alternative in this connector category and does not compromise electrical performance.

Q: Why does the substitute have a narrower operating temperature range?

A: Operating temperature range is determined by material composition and design specifications. The substitute's -40°C ~ 105°C range reflects Mercury's design parameters. Applications requiring the original -55°C ~ 125°C range must confirm actual system operating conditions before substitution.

Q: Is the copper alloy contact material equivalent to phosphor bronze?

A: Yes. Both materials provide equivalent electrical conductivity, corrosion resistance, and spring characteristics for card edge connector applications. Copper alloy is a standard alternative in this connector class.

Q: What does the flange feature difference mean for installation?

A: The original part specifies a 0.142" (3.61mm) diameter unthreaded flange; the substitute specifies 0.156" (3.96mm). Verify that the panel mount opening accommodates the larger diameter before installation.

Q: Does the RoHS3 compliance of the substitute affect compatibility?

A: No. RoHS3 compliance indicates the substitute meets current environmental regulations. This is an advantage for new designs and systems requiring regulatory compliance.

Q: What is the significance of "Dual" Read Out in the substitute vs. "Single" in the original?

A: Read Out configuration refers to contact arrangement. Both configurations support the same 44-position, dual-edge functionality. This variation does not affect substitution compatibility.
