7B-32.000MAAE-T

Crystals Overview

The 7B-32.000MAAE-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, operating at a fundamental frequency of 32.000 MHz. It utilizes a seam-seal ceramic package with dimensions of 5.0 mm x 3.2 mm and features four solder pads. The component exhibits a frequency tolerance and stability of ±30 ppm at 25°C and across the -20°C to +70°C temperature range. It requires a load capacitance of 12 pF and has a maximum equivalent series resistance (ESR) of 40 Ohms for frequencies between 12 MHz and 48 MHz.

Crystals Procurement Notes

This specific part number is officially obsolete and no longer in active manufacturing. Procurement should focus on verified substitute models available from authorized distributors. Buyers must confirm current availability and lead times directly with suppliers, as stock levels vary. Ensure that any replacement component matches the required electrical specifications and physical footprint to maintain circuit integrity without redesign.

Crystals Selection Notes

Engineers selecting this component should prioritize alternatives within the same manufacturer's portfolio due to its discontinued status. Key selection criteria include matching the 32 MHz frequency, 12 pF load capacitance, and ±30 ppm stability requirements. Verify that the substitute maintains the 5.0x3.2 mm package size and 4-SMD no-lead configuration to ensure compatibility with existing PCB layouts and assembly equipment.

Crystals Part Context

The 7B series represents TXC Corporation's line of small-volume surface-mount crystals designed for space-constrained applications. This specific model belongs to the 5032 package family, which offers a significant reduction in PCB area compared to traditional through-hole packages like HC-49S. The series is engineered to support various wireless standards while maintaining strict frequency stability.

Crystals Replacement Considerations

The confirmed public substitute for this obsolete part is the 7M-32.000MAAE-T from TXC Corporation. This alternative provides similar electrical performance and packaging dimensions. Users should verify that the 7M series meets all original design constraints before implementation.
