FDC500016 Equivalent & Substitute Parts

Part Overview

The FDC500016 is a 125 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FD series. This surface mount crystal oscillator operates at 2.5V with Enable/Disable functionality and is designed for applications requiring stable frequency generation in compact form factors. The device is Active status and widely used in telecommunications, networking, and industrial equipment. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FDC500016 is determined by strict equivalence across the following critical parameters:

• Frequency: Must be 125 MHz (no deviation)
• Output Configuration: Must be CMOS
• Supply Voltage: Must be 2.5V
• Enable/Disable Function: Must be present
• Package Type: Must be 4-SMD, No Lead
• Physical Dimensions: Must match 5.00mm x 3.20mm x 1.30mm (max height)
• Operating Temperature Range: Must cover -20°C ~ 70°C minimum
• Compliance: Must maintain ROHS3 and REACH compliance status

The FDC500015 qualifies as a direct substitute based on full alignment with these parameters. Frequency stability tolerance differs (±25ppm vs. ±20ppm on the main part), but this represents a relaxed specification that remains within acceptable substitution criteria for this oscillator category.

Parameter Comparison

Engineering Selection Recommendations

Both FDC500016 and FDC500015 are Active status components from Diodes Incorporated, ensuring ongoing manufacturer support and supply chain stability. Selection between these parts should be based on:

FDC500016: Primary choice when frequency stability of ±20ppm is a design requirement. Current inventory of 1017 units supports immediate availability.

FDC500015: Acceptable alternative when frequency stability tolerance of ±25ppm meets application requirements. Current inventory of 657 units is available. This part is manufacturer-recommended as an equivalent.

Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications. Physical footprint and electrical interface are fully interchangeable, permitting direct PCB layout reuse without modification.

Frequently Asked Questions (FAQ)

Q: Can FDC500015 be used as a direct replacement for FDC500016 on existing PCBs?

A: Yes. Both parts share identical package type (4-SMD, No Lead), physical dimensions (5.00mm x 3.20mm x 1.30mm), pinout configuration, and electrical interface. No PCB layout changes are required.

Q: What is the difference in frequency stability between these parts?

A: FDC500016 specifies ±20ppm frequency stability, while FDC500015 specifies ±25ppm. The FDC500015 tolerance is relaxed by 5ppm. Applications requiring tighter stability should use FDC500016.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both FDC500016 and FDC500015 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operating temperature range for both oscillators?

A: Both parts operate across -20°C to 70°C, supporting industrial and commercial temperature environments.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both FDC500016 and FDC500015 include Enable/Disable control, allowing dynamic power management with 10µA maximum disable mode current.

Q: What is the supply current requirement?

A: Both parts draw a maximum of 35mA during normal operation and 10µA in disable mode at 2.5V supply voltage.
