CPPFXT1-A7BD-50.0TS Equivalent & Substitute Parts

Part Overview

The CPPFXT1-A7BD-50.0TS is a 50 MHz XO (Standard) TTL Oscillator manufactured by Cardinal Components Inc., designed for through-hole mounting in 14-DIP Module configuration with 4 leads. This component operates at 5V with enable/disable functionality and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is essential for system redesign, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPPFXT1-A7BD-50.0TS are identified based on the following critical parameters that must align for functional equivalence:

• Frequency: 50 MHz (exact match required)
• Output Type: TTL or HCMOS/TTL compatible output
• Supply Voltage: 5V operation
• Function: Enable/Disable capability
• Mounting Type: Through Hole
• Package Configuration: 14-DIP, 4 Leads

The ACO-50.000MHZ-EK from Abracon LLC meets these core substitution criteria. While minor variations exist in frequency stability, operating temperature range, and maximum supply current, the part maintains functional compatibility for 50 MHz TTL oscillator applications requiring enable/disable control.

Parameter Comparison

Engineering Selection Recommendations

The ACO-50.000MHZ-EK is an active product from Abracon LLC and represents a viable substitute for the obsolete CPPFXT1-A7BD-50.0TS. Both components are RoHS compliant and maintain the same 50 MHz frequency, 5V supply voltage, and enable/disable functionality required for TTL oscillator applications.

Key considerations for selection:

• The substitute part operates within a narrower temperature range (-20°C ~ 70°C versus -40°C ~ 85°C). Applications requiring extended low-temperature operation below -20°C or high-temperature operation above 70°C must account for this limitation.
• Frequency stability differs by 10ppm (±30ppm versus ±20ppm). Applications with strict frequency tolerance requirements should evaluate this specification against system requirements.
• Maximum supply current is higher in the substitute (70mA versus 45mA). Power supply design must accommodate this increased current draw.
• Both parts use through-hole mounting in 14-DIP configuration, ensuring mechanical and electrical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the ACO-50.000MHZ-EK directly replace the CPPFXT1-A7BD-50.0TS without PCB modifications?

A: Yes, both parts use identical 14-DIP through-hole mounting with 4 leads. No PCB layout changes are required for mechanical installation. Electrical compatibility is maintained for standard TTL oscillator applications.

Q: What is the significance of the frequency stability difference (±20ppm vs ±30ppm)?

A: Frequency stability defines the maximum deviation from the nominal 50 MHz frequency across operating conditions. The main part offers tighter tolerance. Applications sensitive to frequency drift should evaluate whether ±30ppm stability meets system requirements.

Q: Why does the substitute part have a lower operating temperature range?

A: The ACO-50.000MHZ-EK operates from -20°C to 70°C, compared to the main part's -40°C to 85°C range. If your application requires operation outside the -20°C to 70°C window, the substitute part is not suitable without additional thermal management or alternative sourcing.

Q: Is the higher supply current (70mA vs 45mA) a concern?

A: The substitute part draws 25mA more current at maximum. Verify that your power supply and circuit design can accommodate this increased current without voltage regulation issues or thermal stress.

Q: Are both parts RoHS compliant?

A: Yes. The main part is RoHS Compliant, and the substitute is ROHS3 Compliant, ensuring both meet environmental and regulatory requirements for lead-free manufacturing.

Q: What does "Active" product status mean for the substitute?

A: Active status indicates the ACO-50.000MHZ-EK is currently manufactured and available from the supplier, ensuring long-term availability and supply chain stability compared to the obsolete main part.
