Substitute Part Grouping Explanation

Substitution eligibility for the EB73S-SA1560V is determined by strict alignment with the following critical parameters:

Connector Type & Configuration: Card edge dual female connector with 30 positions
Pitch Specification: 0.156" (3.96mm) center-to-center spacing
Card Thickness Accommodation: Support for 0.054" to 0.071" card thickness range
Electrical Interface: Dual row, 15 positions per row configuration
Termination Method: Solder eyelet termination for PCB mounting
Contact Finish: Gold plating for corrosion resistance and signal integrity
Mounting Configuration: Panel mount, flush mount design

The substitute part 356-015-500-104 (Mercury United Electronics, Inc.) meets these core functional requirements. Variations in contact material composition, contact type geometry, and operating temperature range do not preclude substitution when the primary electrical and mechanical interfaces remain compatible.

Engineering Selection Recommendations

The 356-015-500-104 is the designated manufacturer-recommended substitute for the EB73S-SA1560V. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Regulatory Compliance: The 356-015-500-104 achieves ROHS3 compliance, meeting current environmental and material restriction requirements. The original EB73S-SA1560V is RoHS non-compliant and does not meet modern procurement standards.

Mechanical Compatibility: Both connectors accommodate the same card thickness range (0.054" to 0.070/0.071"), ensuring physical fit within existing PCB edge slot designs. The substitute's maximum thickness tolerance of 0.070" remains within the original specification envelope.

Electrical Interface: Identical pitch (0.156"), position count (30), and dual-row configuration ensure direct electrical compatibility without redesign of mating card edge connectors or PCB layouts.

Thermal Operating Range: The substitute operates across -40°C to 105°C, which covers the majority of industrial and commercial applications. Systems requiring the full -55°C to 125°C range of the original part require thermal performance verification.

Frequently Asked Questions (FAQ)

Q: Can the 356-015-500-104 be used as a direct replacement for the EB73S-SA1560V without PCB modification?

A: Yes. Both connectors share identical pitch (0.156"), position count (30), dual-edge configuration, and panel mount solder eyelet termination. The card thickness accommodation range is compatible (0.054" to 0.070" vs. 0.054" to 0.071"). No PCB layout changes are required.

Q: What is the difference in contact material between the two parts?

A: The EB73S-SA1560V uses phosphor bronze contacts, while the 356-015-500-104 uses copper alloy contacts. Both materials are gold-plated and suitable for signal transmission in card edge connector applications. Contact material composition does not affect mechanical or electrical interface compatibility.

Q: Does the operating temperature difference affect substitution suitability?

A: The substitute part operates from -40°C to 105°C, compared to the original -55°C to 125°C range. For applications within the -40°C to 105°C envelope, the substitute is fully suitable. Applications requiring operation below -40°C or above 105°C require thermal performance evaluation.

Q: Is the 356-015-500-104 RoHS compliant?

A: Yes. The 356-015-500-104 is ROHS3 compliant. The original EB73S-SA1560V is RoHS non-compliant. This compliance difference is significant for procurement in regulated industries and modern supply chain requirements.

Q: What is the difference between "Full Bellows" and "Cantilever" contact types?

A: The EB73S-SA1560V uses full bellows contacts, while the 356-015-500-104 uses cantilever contacts. Both contact geometries provide reliable electrical connection in card edge applications. The contact type difference does not preclude substitution when pitch, position count, and card thickness specifications align.

Q: Are there any packaging differences between the main part and substitute?

A: The EB73S-SA1560V packaging is listed as unspecified. The 356-015-500-104 is supplied in bulk packaging. Both are suitable for standard PCB assembly processes.
