MC-77233
50-Cavity Small Component Tray
A 50-cavity tray with closely arranged 0.700″ square pocket references. Available in black conductive and clear antistatic material.
Does this tray look close to what you need? Send us your device information. Malaster can help review the fit, material choice and requirements for your application.
Discuss This Tray for Your Application
Mention MC-77233 when you contact us.

A starting point for your device
The MC-77233 places fifty individual square pockets in a ten-by-five grid within an 8.874″ × 4.624″ footprint. The regular arrangement can be a useful starting point for handling multiple small components separately.
Send the component outline, corner shape and thickness, along with the required pickup method. Closely arranged cavities still need suitable clearance for the device and for removing it without disturbing adjacent positions.
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-77233 |
|---|---|
| Cavity layout | 50 square cavities in a 10 × 5 arrangement |
| Reference application | Small square electronic components |
| Reference cavity length × width | 0.700″ × 0.700″ Approximately 17.8 × 17.8 mm |
| Reference cavity depth | 0.230″ Approximately 5.8 mm |
| Overall footprint | 8.874″ × 4.624″ Approximately 225.4 × 117.4 mm |
| Reference overall height | 0.400″ Approximately 10.2 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 regular pocket grid and separating walls. The tray has a 0.230″ reference cavity depth and a 0.400″ overall height; compare the cavity profile with the part’s thickness and seating requirements.
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-77233 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-77233 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-77233 in your inquiry so we can refer to this tray design.
