12-Cavity Component Tray
A twelve-cavity tray with broad rectangular pockets, circular base openings and formed access recesses. 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-77231 when you contact us.
A starting point for your device
The main MC-77231 configuration uses twelve 2.125″ × 2.000″ reference pockets within a 10.625″ × 8.750″ footprint. This reference table applies to the twelve-cavity configuration. A separate dimensional table for the MC-77231-A six-cavity configuration appears below.
Tell us where the component may contact the pocket floor and how it will be removed. Circular base openings and curved access recesses make the underside geometry and handling method particularly relevant.
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-77231 |
|---|---|
| Cavity layout | 12 cavities in a 4 × 3 arrangement; separate six-cavity configuration shown below |
| Reference application | Components needing broad pockets and access openings |
| Reference cavity length × width | 2.125″ × 2.000″ Approximately 54.0 × 50.8 mm |
| Reference cavity depth | 0.500″ Approximately 12.7 mm |
| Overall footprint | 10.625″ × 8.750″ Approximately 269.9 × 222.3 mm |
| Reference overall height | 0.550″ Approximately 14.0 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 twelve-cavity line view shows the base openings, pocket walls and curved relief between rows. Their function should be reviewed against the actual component and the intended loading or removal process.
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.
MC-77231-A six-cavity configuration
MC-77231-A has six pockets in a 2 × 3 arrangement, with circular base openings and curved access relief. Its 8.500″ × 5.687″ footprint and profile dimensions are shown separately below. Mention MC-77231-A when discussing this six-cavity configuration.
| Configuration reference | MC-77231-A |
|---|---|
| Cavity layout | 6 cavities in a 2 × 3 arrangement |
| Reference cavity profile in plan | 2.180″ × 2.070″ Approximately 55.4 × 52.6 mm |
| Reference inner profile width | 2.120″ Approximately 53.8 mm |
| Reference section A–A height | 0.415″ Approximately 10.5 mm |
| Overall footprint | 8.500″ × 5.687″ Approximately 215.9 × 144.4 mm |
| Reference overall height | 0.535″ Approximately 13.6 mm |
The plan profile, inner width and section height describe different features. Use them together with your device outline to review support, clearance and removal access. The section-height reference is separate from overall tray height.
Choose a material for your application
MC-77231 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-77231 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-77231 in your inquiry so we can refer to this tray design.
