EB73D-SA154X1 Card Edge Connector Equivalent & Substitute Parts

Part Overview

The EB73D-SA154X1 is a 30-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, full bellows contact type, and panel mount configuration with solder eyelet termination. The part is classified as obsolete, making identification of active equivalent components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the EB73D-SA154X1 is determined by strict equivalence across the following critical parameters:

Connector Configuration: Dual-edge, female gender, 30-position arrangement (15 positions per row)
Electrical Interface: 0.156" (3.96mm) pitch spacing for direct PCB compatibility
Contact Specifications: Phosphor bronze material with gold plating and full bellows contact type
Mechanical Interface: Panel mount configuration with solder eyelet termination
Environmental Rating: Operating temperature range and moisture sensitivity classification
Compliance Status: RoHS and REACH compliance requirements

The GSM15DSEH from Sullins Connector Solutions meets these substitution criteria as an active product with compatible electrical and mechanical specifications.

Engineering Selection Recommendations

The GSM15DSEH represents a direct functional equivalent to the EB73D-SA154X1 across all critical electrical and mechanical parameters. The substitute part offers the following advantages:

Active Product Status: GSM15DSEH is actively manufactured and supported, ensuring long-term availability and supply chain continuity compared to the obsolete EB73D-SA154X1.
Regulatory Compliance: GSM15DSEH achieves ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original part is non-compliant.
Enhanced Temperature Range: The substitute part supports -65°C minimum operating temperature, extending the lower temperature capability by 10°C compared to the original specification.
Consistent Electrical Interface: Both parts maintain identical pitch spacing (0.156"), position count (30), and contact configuration, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can GSM15DSEH be used as a direct replacement for EB73D-SA154X1 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical interfaces: 30-position dual-edge configuration, 0.156" pitch, phosphor bronze gold-plated contacts with full bellows type, panel mount configuration, and solder eyelet termination. The card thickness specification of 0.062" for GSM15DSEH falls within the 0.054" to 0.071" acceptance range of the original part.

Q: What are the key differences between these two parts?

A: The primary differences are product status, compliance certification, and insulation material. EB73D-SA154X1 is obsolete and RoHS non-compliant, while GSM15DSEH is an active product with ROHS3 compliance. Insulation material differs (polyester thermoplastic glass-filled versus polyamide nylon 9T), and GSM15DSEH provides an extended lower operating temperature limit of -65°C versus -55°C.

Q: Are there any mechanical compatibility concerns when substituting GSM15DSEH for EB73D-SA154X1?

A: No mechanical compatibility issues exist. Both connectors feature identical mounting type (panel mount), termination method (solder eyelet), flange configuration (top opening, unthreaded), and contact specifications. The card thickness of 0.062" for GSM15DSEH is within the specified tolerance range of the original connector.

Q: Does the change in insulation material affect electrical performance?

A: No. Both polyester thermoplastic glass-filled and polyamide (PA9T) nylon 9T materials are suitable for the specified operating temperature range and provide equivalent electrical insulation properties for this connector application.

Q: What is the availability status of GSM15DSEH compared to EB73D-SA154X1?

A: GSM15DSEH is actively manufactured by Sullins Connector Solutions with current inventory availability. EB73D-SA154X1 is obsolete and no longer in production, making GSM15DSEH the recommended choice for new designs and ongoing system support.
