Part Change Notice #11020: Part Change Notification

Products Affected: CFAL12832D-B, CFAL12832D-CW, CFAL12832D-CY, CFAL12832D-PW, CFAL12832D-PY, CFAL12832D-BY, CFAL12832D-BB
Date Issued: November 1, 2018
Summary: Part Change Notification
Description: The parts listed are being replaced by new part numbers.
Reason: The glass used in these displays is being replaced by thinner more efficient glass.
Impact: The part numbers listed will be replaced by new part numbers. The operation of the displays will not change. The overall thickness of each of the displays will decrease by 0.05mm.

The part number changes are:

CFAL12832D-CW - CFAL12832B-0091C-W
CFAL12832D-PY - CFAL12832B-0091P-Y
CFAL12832D-PW - CFAL12832B-0091P-W
CFAL12832D-B - CFAL12832B-0091B-W
CFAL12832D-BB - CFAL12832B-0091B-B
CFAL12832D-BY - CFAL12832B-0091B-Y
Recommendation: Users are recommended to verify that the change in the thickness dimension will not affect the installation of the displays.
Availability: The new parts will be available when current stock is depleted.

Product Notes

This module is engineered for high volume production. It uses a "TAB" (tape automated bonding) or "COF" (chip on flex) style flex tail mated with a thin display. The TAB connector must soldered directly to corresponding pads on your PCB using a hot-bar soldering machine, or bonded with anisotropic adhesive using heat and pressure. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost. The TAB style connection requires no separate connector, so the cost is very low, and the ultra thin profile of the display is maintained.
