Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB73D-SA1040W is determined by strict alignment across the following critical parameters:

• Connector Type & Configuration: 20-position female card edge connector with dual-edge, dual-row (2 rows × 10 positions per row) architecture
• Electrical Interface: 0.156" (3.96mm) pitch spacing with solder eyelet termination
• Contact Specifications: Phosphor bronze base material with gold finish for corrosion resistance and electrical conductivity
• Mechanical Compatibility: Card thickness tolerance range and mounting type (free hanging, in-line)
• Environmental Rating: Operating temperature range and moisture sensitivity classification

The GSM10DSEN from Sullins Connector Solutions meets these substitution criteria through functional equivalence across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The GSM10DSEN is the qualified substitute for the EB73D-SA1040W based on the following engineering factors:

Functional Equivalence: Both connectors maintain identical electrical and mechanical specifications across position count, pitch, contact material, and termination method. The GSM10DSEN's card thickness specification of 0.062" falls within the EB73D-SA1040W tolerance band of 0.054" to 0.071", ensuring mechanical compatibility with existing card edge designs.

Product Lifecycle Status: The EB73D-SA1040W is obsolete, while GSM10DSEN is actively manufactured by Sullins Connector Solutions. Active production status ensures long-term availability and supply chain continuity.

Compliance Posture: GSM10DSEN achieves ROHS3 compliance, whereas the EB73D-SA1040W is RoHS non-compliant. For applications subject to current regulatory requirements, GSM10DSEN provides compliance alignment. Both parts maintain REACH Unaffected status and EAR99 export classification.

Environmental Performance: GSM10DSEN extends the lower operating temperature limit to -65°C compared to the EB73D-SA1040W at -55°C, providing enhanced cold-temperature performance without compromising upper temperature capability (both rated to 125°C).

Material Substitution: GSM10DSEN employs Polyamide (PA9T) Nylon 9T insulation versus the EB73D-SA1040W's polyester thermoplastic with glass fill. Both materials provide equivalent electrical and mechanical performance for this connector class.

Frequently Asked Questions (FAQ)

Q: Can GSM10DSEN directly replace EB73D-SA1040W in existing designs?

A: Yes. Both connectors share identical position count (20), pitch spacing (0.156"), gender (female), contact material (phosphor bronze with gold finish), and termination method (solder eyelet). The GSM10DSEN card thickness specification of 0.062" is within the EB73D-SA1040W tolerance range of 0.054" to 0.071", ensuring mechanical fit with existing card edge designs.

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

A: The EB73D-SA1040W uses polyester thermoplastic with glass fill, while GSM10DSEN uses Polyamide (PA9T) Nylon 9T. Both materials provide equivalent electrical insulation properties, mechanical strength, and thermal stability for this connector application. Material selection does not affect electrical performance or compatibility.

Q: Why is RoHS compliance important for this substitution?

A: GSM10DSEN is ROHS3 compliant while EB73D-SA1040W is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, GSM10DSEN ensures compliance with current environmental and hazardous substance restrictions. The EB73D-SA1040W may be restricted from use in regulated markets.

Q: Does the extended temperature range of GSM10DSEN affect compatibility?

A: No. GSM10DSEN's operating range of -65°C to 125°C encompasses the EB73D-SA1040W range of -55°C to 125°C. The extended lower temperature capability provides additional margin without introducing any compatibility issues.

Q: What packaging format is GSM10DSEN supplied in?

A: GSM10DSEN is supplied in Tray packaging, whereas the EB73D-SA1040W packaging specification is not detailed. Confirm tray packaging compatibility with your assembly and handling processes.

Q: Are there any electrical performance differences between these connectors?

A: No. Both connectors use identical contact material (phosphor bronze), contact finish (gold), and contact type (full bellows). Electrical performance characteristics including contact resistance, current rating, and signal integrity are equivalent.
