Parameter Comparison

Engineering Selection Recommendations

The 306-006-500-101 (Mercury United Electronics, Inc.) is the documented manufacturer-recommended substitute for the obsolete EB72S-SA0640W. This substitution is supported by:

Functional Equivalence: Both connectors maintain identical electrical and mechanical interface specifications across all critical parameters: 12-position female configuration, 0.156" pitch, dual-edge card type, 2-row layout, and solder eyelet termination.

Mechanical Compatibility: Card thickness tolerance ranges are compatible within the specified operating envelope (0.054" ~ 0.070" for the substitute versus 0.054" ~ 0.071" for the original).

Compliance Improvement: The substitute part carries ROHS3 compliance status, addressing regulatory requirements that the original non-compliant part does not satisfy. Both parts maintain REACH unaffected status and EAR99 export classification.

Operational Considerations: The substitute part operates across -40°C to 105°C, which is narrower than the original -55°C to 125°C range. Applications requiring operation below -40°C or above 105°C must be evaluated against actual system requirements.

Product Availability: The substitute part maintains active product status with documented inventory availability, ensuring long-term procurement viability compared to the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can the 306-006-500-101 be used as a direct replacement for the EB72S-SA0640W?

A: Yes. Both connectors share identical electrical interface specifications (12 positions, 0.156" pitch, female gender, gold-plated contacts, solder eyelet termination) and mechanical form factor (dual-edge, 2-row configuration, free-hanging mounting). The substitute is the manufacturer-recommended equivalent.

Q: What is the difference in card thickness tolerance between these connectors?

A: The EB72S-SA0640W accepts card thickness of 0.054" ~ 0.071" (1.37mm ~ 1.80mm), while the 306-006-500-101 accepts 0.054" ~ 0.070" (1.37mm ~ 1.78mm). The substitute has a marginally tighter upper tolerance limit of 0.001" (0.02mm). Cards within the 0.054" ~ 0.070" range are compatible with both connectors.

Q: Does the operating temperature range difference affect substitution?

A: The original part operates -55°C to 125°C; the substitute operates -40°C to 105°C. For applications requiring operation below -40°C or above 105°C, the substitute does not meet the original specification. For standard industrial temperature ranges (-40°C to 85°C), both parts are functionally equivalent.

Q: What is the difference between phosphor bronze and copper alloy contact materials?

A: Both materials provide equivalent electrical conductivity and mechanical performance for this connector class. Phosphor bronze offers slightly higher spring characteristics; copper alloy provides comparable contact reliability. For this application, both materials satisfy the functional requirements of the connector interface.

Q: Is the 306-006-500-101 RoHS compliant?

A: Yes. The 306-006-500-101 carries ROHS3 compliance status. The original EB72S-SA0640W is RoHS non-compliant. If RoHS compliance is required for your application, the substitute part satisfies this regulatory requirement.

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

A: The 306-006-500-101 specifies 10.0µin (0.25µm) gold contact finish thickness. The original part does not document this specification. Both parts use gold plating for corrosion resistance and electrical performance.
