EB73S-SB1540X Card Edge Connector Equivalent & Substitute Parts

Part Overview

The Vishay Dale EB73S-SB1540X is a dual edge female card edge connector with 30 positions (two rows, 15 positions per row) in the Card Edge Connectors category. This connector features gold-plated, full bellows phosphor bronze contacts, through-hole mounting, 0.156" (3.96mm) pitch, and is designed for cards 0.054" ~ 0.071" (1.37mm ~ 1.80mm) thick. The product is black, flush mount, unthreaded, and RoHS non-compliant. Its status is obsolete, making it necessary to identify substitute parts with equivalent parameters for ongoing designs, maintenance, or repair.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected by strict comparison of the following mandatory parameters for the card edge connectors category: number of positions, number of rows, card thickness compatibility, pitch, mounting type, termination method, gender, flange feature, contact finish, color, and operating temperature range. Substitutes must match or be within specified tolerances of these parameters to ensure form, fit, and electrical compatibility.

Key parameters for substitution:

• Number of Positions: 30
• Number of Rows: 2
• Card Thickness Compatibility: 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Pitch: 0.156" (3.96mm)
• Mounting Type: Through Hole
• Termination: Solder
• Gender: Female
• Flange Feature: Flush Mount, Top Opening, Unthreaded, 0.128" (3.25mm) Dia
• Color: Black
• Contact Finish: Gold

Parameter Comparison

Engineering Selection Recommendations

The EB73S-SB1540X is categorized as obsolete. Substitute part 356-015-520-102 from Mercury United Electronics, Inc. is currently active and RoHS3 compliant, whereas the original part is RoHS non-compliant. Substitute selection must also consider regulatory compliance (RoHS) and MSL ratings, which are provided for both parts. All substitutions in this group are based solely on documented parameters and compliance information.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for selecting a card edge connector substitute?
A1: The primary criteria include number of positions, number of rows, card thickness compatibility, pitch, mounting type, termination method, gender, flange features, contact finish, color, and regulatory compliance such as RoHS.

Q2: Is package type or mounting style considered for substitution?
A2: Yes, both package or packaging type (Bulk) and mounting style (Through Hole) are explicit parameters and must match between main and substitute parts.

Q3: How is RoHS compliance addressed between original and substitute parts?
A3: The original EB73S-SB1540X is RoHS non-compliant, while the substitute 356-015-520-102 is ROHS3 compliant. Selection must conform to the required regulatory compliance for the application.

Q4: Are the flange features identical between the main and substitute parts?
A4: Yes, both parts feature flush mount, top opening, unthreaded settings with a 0.128" (3.25mm) diameter.

Q5: Is there a difference in insulation material or contact materials to consider?
A5: Differences in insulation and contact material are specified: the original uses polyester, glass filled insulation and phosphor bronze contacts; the substitute uses polyester thermoplastic insulation and copper alloy contacts. Only the materials provided are listed for selection criteria.

Q6: Does the substitute support the same card thickness range?
A6: The substitute supports a card thickness range of 0.054" ~ 0.070" (1.37mm ~ 1.78mm), compared to 0.054" ~ 0.071" (1.37mm ~ 1.80mm) for the original part.

Q7: Is stocking status or product activity level a consideration?
A7: Yes, with the EB73S-SB1540X obsolete, active substitutes such as 356-015-520-102 are listed to maintain continuity for qualified applications.
