Discuss This Tray for Your Application
Mention MC-77112 when you contact us.

A starting point for your device
The MC-77112 places twelve broad, square pockets in a four-by-three arrangement. Its 14.500″ × 10.125″ footprint and 0.625″ reference cavity depth provide a starting point for reviewing larger socket housings and similarly shaped components.
Socket latches, terminals, mounting features and underside projections can extend beyond the main body. Send the complete outline so we can review the pocket, support surfaces and access for removal.
If your device differs from the reference application, contact us anyway. We can discuss whether this tray, another existing design or a custom packaging solution is worth exploring.
Tray at a glance
| Tray reference | MC-77112 |
|---|---|
| Cavity layout | 12 cavities in a 4 × 3 arrangement |
| Reference application | Large sockets and similarly sized components |
| Reference cavity length × width | 2.760″ × 2.760″ Approximately 70.1 × 70.1 mm |
| Reference cavity depth | 0.625″ Approximately 15.9 mm |
| Overall footprint | 14.500″ × 10.125″ Approximately 368.3 × 257.2 mm |
| Reference overall height | 0.752″ Approximately 19.1 mm |
| Material options | Black conductive Clear antistatic |
Use these reference dimensions for an initial size comparison. Actual fit depends on the device profile, pin clearances and selected material. If your device is close to these dimensions, contact us to review the fit.

Look beyond the overall size
The line view shows the broad pocket floors, formed walls and rounded corners. These details help us compare the housing outline and seating position with the tray.
Tell us how the tray will be used, whether for work-in-process handling, storage or a shipping application. We can then review the tray as part of the complete packaging requirement.
Choose a material for your application
MC-77112 is available in both black conductive and clear antistatic material. Tell us about your ESD requirements, handling environment and any need to see the device through the tray so we can discuss the appropriate option.
Black conductive
An option for applications requiring conductive tray material. Share your material or ESD specifications so we can review the requirements with you.
Clear antistatic
An option when clear material is useful for viewing the device. We can discuss the antistatic material requirements alongside fit and handling.
Could MC-77112 work for your device?
You do not need a complete specification to begin. Send what you have, and we can help identify the details needed to assess the tray and prepare a quotation.
- A device drawing, photograph, package outline or description
- Any known dimensions, pin clearances or handling concerns
- Your material preference or ESD requirements, if known
- Estimated quantities and timing
Please include MC-77112 in your inquiry so we can refer to this tray design.
