EB73D-SA1860V Equivalent & Substitute Parts

Part Overview

The EB73D-SA1860V is a 36-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 solder eyelet termination. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution compatibility for the EB73D-SA1860V is determined by the following critical parameters:

Connector Configuration: 36-position dual female card edge connector with 0.156" pitch
Contact System: Phosphor bronze with gold plating and full bellows contact type
Mechanical Interface: Panel mount with solder eyelet termination
Electrical Performance: Operating temperature range and contact material consistency
Card Accommodation: Card thickness tolerance that accommodates the original specification range

The GMM18DSEH from Sullins Connector Solutions meets these substitution criteria. Both connectors share identical position count, pitch spacing, contact material composition, gold finish, mounting methodology, and termination style. The substitute maintains functional and electrical equivalence within the specified parameter boundaries.

Engineering Selection Recommendations

The GMM18DSEH serves as the direct functional equivalent for the obsolete EB73D-SA1860V. Selection of the substitute is based on the following engineering factors:

Product Availability: The EB73D-SA1860V is obsolete with no ongoing manufacturing. The GMM18DSEH is an active product with current production and inventory availability.

Compliance Status: The GMM18DSEH is RoHS3 compliant, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. Both parts maintain REACH Unaffected status and EAR99 export classification.

Electrical and Mechanical Equivalence: The substitute maintains identical contact configuration, pitch spacing, termination method, and mounting interface. The phosphor bronze contact material with gold plating ensures equivalent electrical performance and signal integrity.

Temperature Performance: The GMM18DSEH extends the lower operating temperature limit to -65°C, providing enhanced performance margin compared to the original -55°C specification.

Material Consideration: The substitute uses polyamide (PA9T) nylon 9T insulation versus the original polyester thermoplastic. Both materials are suitable for the specified operating temperature range and provide equivalent mechanical and electrical insulation properties.

Frequently Asked Questions (FAQ)

Q: Can the GMM18DSEH directly replace the EB73D-SA1860V in existing designs?

A: Yes. Both connectors share identical position count, pitch spacing, contact material, gold finish, mounting configuration, and solder eyelet termination. The mechanical and electrical interfaces are equivalent.

Q: What is the significance of the different insulation materials?

A: The original uses polyester thermoplastic with glass filling; the substitute uses polyamide (PA9T) nylon 9T. Both materials provide adequate insulation performance across the operating temperature range. The polyamide material in the substitute is a standard alternative in modern connector design.

Q: Does the card thickness difference affect compatibility?

A: The original specification accommodates cards from 0.054" to 0.071" (1.37mm to 1.80mm). The substitute is rated for 0.062" (1.57mm) cards, which falls within the original tolerance range. Verify your specific card thickness against both specifications.

Q: What is the advantage of the extended temperature range in the substitute?

A: The GMM18DSEH operates from -65°C to 125°C, compared to the original -55°C to 125°C. This provides a 10°C margin at the lower temperature limit, beneficial for applications in extreme cold environments.

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

A: The EB73D-SA1860V packaging is not specified in available documentation. The GMM18DSEH is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What is the RoHS compliance impact?

A: The original EB73D-SA1860V is RoHS non-compliant. The GMM18DSEH is RoHS3 compliant. If your application or market requires RoHS compliance, the substitute meets this requirement.
