Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB72S-SA0640V is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 12
• Gender: Female
• Pitch: 0.156" (3.96mm)
• Card Type: Dual Edge
• Mounting Type: Panel Mount
• Termination: Solder Eyelet(s)

Compatible Variation Parameters:

• Card Thickness Range: Substitute must accommodate the original range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Contact Material: Phosphor Bronze or Copper Alloy acceptable
• Contact Finish: Gold plating required
• Contact Type: Full Bellows or Cantilever acceptable
• Operating Temperature: Substitute range must encompass or exceed the original -55°C ~ 125°C specification

The substitute part 306-006-500-104 meets all mandatory matching parameters and operates within compatible variation ranges, establishing direct substitution capability.

Engineering Selection Recommendations

The 306-006-500-104 manufactured by Mercury United Electronics, Inc. is the qualified substitute for the obsolete EB72S-SA0640V. This substitution is supported by:

Product Status Advantage: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Compliance Improvement: The 306-006-500-104 achieves ROHS3 compliance, representing an upgrade from the non-compliant status of the original part. Both components maintain REACH Unaffected and EAR99 ECCN classifications.

Functional Equivalence: All critical electrical and mechanical parameters align with the original specification. The substitute accommodates the same card thickness range and maintains identical pitch, position count, and termination methodology.

Operating Temperature Consideration: The substitute operates within -40°C ~ 105°C, which provides reduced low-temperature coverage compared to the original -55°C specification. Applications requiring operation below -40°C require engineering evaluation.

Contact Design Variation: The substitute employs cantilever contact design versus the original full bellows design. Both contact types are acceptable for dual edge card applications at 0.156" pitch with gold plating.

Frequently Asked Questions (FAQ)

Q: Can the 306-006-500-104 directly replace the EB72S-SA0640V in existing designs?

A: Yes, for applications operating within -40°C ~ 105°C. The substitute matches all mandatory parameters including position count, pitch, card type, and termination method. Applications requiring operation below -40°C require design review.

Q: What is the difference between full bellows and cantilever contact types?

A: Both contact types provide reliable electrical connection for dual edge card applications. Full bellows contacts offer increased compliance and contact pressure distribution, while cantilever contacts provide direct spring force. At 0.156" pitch with gold plating, both designs are functionally equivalent for this application category.

Q: Does the substitute part support the same card thickness range?

A: The substitute supports 0.054" ~ 0.070" (1.37mm ~ 1.78mm), which covers the lower end of the original range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm). Cards within 0.054" ~ 0.070" thickness are fully compatible. Cards between 0.070" and 0.071" thickness require verification.

Q: What is the inventory status for the substitute part?

A: The 306-006-500-104 is available with 945 pieces in new original stock, supplied in bulk packaging. The original EB72S-SA0640V has 856 pieces available but is classified as obsolete.

Q: Are there compliance differences between the two parts?

A: The substitute achieves ROHS3 compliance, while the original is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99. For applications subject to RoHS requirements, the substitute provides regulatory compliance advantage.

Q: What is the contact finish thickness specification for the substitute?

A: The 306-006-500-104 specifies 10.0µin (0.25µm) contact finish thickness. The original part does not provide contact finish thickness specification.
