Discuss This Tray for Your Application
Mention MC-77111 when you contact us.

A starting point for your device
The MC-77111 uses four columns of three cavities within a 14.250″ × 10.250″ footprint. The broad pockets and 0.270″ reference cavity depth provide a starting point for reviewing sockets and other components with similar outlines.
Socket bodies may include terminals, latches, locating features or projections that extend beyond the main housing. Send the complete outline and underside details so we can review support and clearance.
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-77111 |
|---|---|
| Cavity layout | 12 cavities in a 4 × 3 arrangement |
| Reference application | Sockets and similarly sized components |
| Reference cavity length × width | 2.525″ × 2.385″ Approximately 64.1 × 60.6 mm |
| Reference cavity depth | 0.270″ Approximately 6.9 mm |
| Overall footprint | 14.250″ × 10.250″ Approximately 361.9 × 260.3 mm |
| Reference overall height | 0.800″ Approximately 20.3 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 pockets and rounded corners. We can consider the device's seating position and removal access alongside the overall tray size.
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-77111 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-77111 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-77111 in your inquiry so we can refer to this tray design.
