FN6250028 Equivalent & Substitute Parts

Part Overview

The FN6250028 is a 62.5 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated as part of the SaRonix-eCera™ FN series. This surface mount crystal oscillator operates at 3.3V with Enable/Disable functionality, housed in a 4-SMD, No Lead package. The device is currently Active in product status with 907 units in stock. Alternative parts may be required due to inventory constraints, design revisions, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FN6250028 is based on the following critical parameters that must remain constant:

• Frequency: 62.5 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Package: 4-SMD, No Lead (identical footprint and pinout)
• Mounting Type: Surface Mount
• Operating Temperature Range: -20°C ~ 70°C minimum
• Compliance: ROHS3 Compliant, REACH Unaffected

The FN6250027 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. The variance in Frequency Stability (±50ppm vs ±25ppm) represents a relaxed tolerance specification and does not prevent substitution in applications where the FN6250028's tighter tolerance is not explicitly required.

Parameter Comparison

Engineering Selection Recommendations

Both FN6250028 and FN6250027 are Active products manufactured by Diodes Incorporated with identical ROHS3 and REACH compliance certifications. Selection between these parts should be based on application-specific frequency stability requirements:

• FN6250028 (±25ppm): Select for applications requiring tighter frequency tolerance specifications.
• FN6250027 (±50ppm): Select when the wider tolerance specification is acceptable and inventory availability is a consideration.

Both parts are suitable for surface mount assembly in identical PCB footprints and require no design modifications for substitution. Current supply characteristics, operating temperature range, and all mechanical parameters are identical, ensuring functional equivalence in the specified operating environment.

Frequently Asked Questions (FAQ)

Q: Can FN6250027 be used as a direct replacement for FN6250028 on the same PCB?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with matching dimensions (7.00mm x 5.00mm) and height (1.80mm). No PCB layout modifications are required.

Q: What is the difference between FN6250028 and FN6250027?

A: The primary difference is frequency stability tolerance. FN6250028 specifies ±25ppm, while FN6250027 specifies ±50ppm. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both FN6250028 and FN6250027 are ROHS3 Compliant and REACH Unaffected.

Q: Do these oscillators require any special handling?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.

Q: What is the maximum supply current for these oscillators?

A: Maximum supply current is 40mA during normal operation. In Disable mode, maximum current is 100µA.

Q: Can these oscillators operate outside the -20°C ~ 70°C temperature range?

A: No. Both parts are specified for operation within -20°C ~ 70°C. Operation outside this range is not supported.
