EB73S-SA0640V Equivalent & Substitute Parts

Part Overview

The EB73S-SA0640V is a 12-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, panel mount configuration, and operates across -55°C to 125°C. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the EB73S-SA0640V is determined by strict alignment of the following critical parameters:

12-position configuration with dual row layout
0.156" (3.96mm) pitch spacing
Female gender with panel mount termination
Gold contact finish
Card thickness accommodation within specified range
Solder eyelet termination method
Black insulation color

The Mercury United Electronics 356-006-500-104 qualifies as a direct substitute based on matching all primary functional parameters. Both connectors accommodate identical card edge geometry, position count, and pitch specifications. Variations in contact material (phosphor bronze versus copper alloy) and contact type (full bellows versus cantilever) remain within acceptable substitution boundaries for this connector category, as both configurations provide equivalent electrical performance at the specified pitch and position density.

Engineering Selection Recommendations

The 356-006-500-104 from Mercury United Electronics serves as the primary substitute for the obsolete EB73S-SA0640V. Selection of this alternative is supported by:

Active product status ensuring continued availability and supply chain stability
ROHS3 compliance, addressing regulatory requirements not met by the original part
Identical pitch, position count, and mechanical interface specifications
Matching termination method and contact finish
Compatible card thickness accommodation within the specified range

The operating temperature range of the substitute (-40°C ~ 105°C) is narrower than the original part (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C must evaluate thermal performance requirements against the substitute's specifications. For standard industrial and commercial applications within the substitute's temperature range, functional equivalence is established.

Frequently Asked Questions (FAQ)

Q: Can the 356-006-500-104 directly replace the EB73S-SA0640V in existing designs?

A: Yes, the 356-006-500-104 provides direct mechanical and electrical compatibility. Both connectors share identical pitch (0.156"), position count (12), row configuration (2), and termination method (solder eyelet). The card thickness accommodation ranges are compatible within the specified limits.

Q: What is the significance of the operating temperature range difference?

A: The original EB73S-SA0640V operates from -55°C to 125°C, while the 356-006-500-104 operates from -40°C to 105°C. Applications operating within the substitute's range experience no thermal performance impact. Systems requiring extended low-temperature operation below -40°C or high-temperature operation above 105°C must confirm the substitute meets thermal requirements.

Q: Does the contact material difference affect electrical performance?

A: Both phosphor bronze (original) and copper alloy (substitute) contacts with gold finish provide equivalent electrical conductivity and signal integrity at the specified pitch and position density. The contact type variation (full bellows versus cantilever) does not compromise functional compatibility for this connector category.

Q: Is the substitute RoHS compliant?

A: Yes, the 356-006-500-104 is ROHS3 compliant, whereas the original EB73S-SA0640V is RoHS non-compliant. This compliance improvement may be required for new designs or regulatory compliance in specific markets.

Q: Are there packaging differences between the original and substitute?

A: The original part packaging is not specified in available documentation. The substitute is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.
