TSP-H00HM50RT-8.000M-TR is listed in the Oscillators range at ChipApex. The manufacturer field lists Transko Electronics, Inc.. Its product description is XTAL OSC XO 8.0000MHZ HCMOS SMD. Review the specifications below when checking this part for your BOM.
The TSP-H00HM50RT-8.000M-TR is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc., operating at a nominal frequency of 8 MHz. It utilizes HCMOS output logic and supports a supply voltage range of 3.3V to 5.0V. The device features enable/disable functionality for power management. It is housed in a 4-SOJ surface-mount package with a 5.08mm pitch, measuring approximately 14.0mm x 9.8mm x 4.7mm. The unit operates within a commercial temperature range of 0°C to 70°C and has a maximum supply current of 45mA.
Verify the specific suffix 'TR' indicates tape and reel packaging configuration when sourcing components. Confirm that the 4-SOJ package dimensions match the target PCB footprint, as this model differs from smaller SMD variants like the TSM32 series. Ensure the supply voltage aligns with the 3.3V to 5.0V operational range specified for this part number.
Select this component when a larger SOJ form factor is acceptable or required for mechanical stability compared to miniaturized DFN packages. It serves as a direct functional replacement for discontinued Epson Toyocom SG-636 models. Consider the 45mA maximum current consumption for power budget calculations in battery-operated applications where lower current MEMS alternatives might be preferred.
This oscillator belongs to the TSP series, which consists of plastic molded standard SMD oscillators. The TSP series is explicitly marketed by Transko Electronics as a drop-in replacement for the Epson Toyocom SG-636 model, ensuring fit, form, and function compatibility. The series offers various frequencies and voltage options within the same physical package constraints.
Publicly confirmed substitute: Epson Toyocom SG-636.
