Key Parameters

Substitute Part Grouping Explanation

The Fox Electronics FC4SDCBMF12.0-T1 qualifies as a substitute for the Crystek 016906 based on the following critical parameters:

• Frequency Match: Both components operate at 12 MHz
• Operating Mode: Both utilize fundamental mode operation
• Mounting Configuration: Both are surface mount devices
• Regulatory Compliance: Both maintain REACH Unaffected status and EAR99 ECCN classification
• Moisture Sensitivity: Both are rated MSL 1 (Unlimited)
• Tariff Classification: Both share HTSUS code 8541.60.0050

The Fox Electronics substitute provides additional specified parameters including frequency tolerance (±30ppm), load capacitance (20pF), ESR (60 Ohms), and operating temperature range (-20°C ~ 70°C), which were not provided for the original Crystek part.

Parameter Comparison

Engineering Selection Recommendations

The Fox Electronics FC4SDCBMF12.0-T1 is suitable for applications requiring a 12 MHz fundamental mode crystal in surface mount configuration. The substitute maintains full regulatory compliance with REACH and export control requirements identical to the original Crystek part. Active product status ensures ongoing availability and supply chain continuity. The specified operating temperature range (-20°C ~ 70°C) and load capacitance (20pF) should be verified against circuit design requirements prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the Fox Electronics FC4SDCBMF12.0-T1 directly replace the Crystek 016906?

A: Yes, both components share identical frequency (12 MHz), operating mode (Fundamental), mounting type (Surface Mount), and regulatory classifications. The Fox Electronics part is actively manufactured, whereas the Crystek part is obsolete.

Q: What is the significance of the HC-49/US package specification?

A: The HC-49/US package designation indicates the physical form factor and pin configuration. This specification is provided for the Fox Electronics substitute but was not documented for the original Crystek part. Mechanical compatibility should be confirmed with circuit board layout specifications.

Q: Are there any compliance differences between these parts?

A: No. Both components maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS tariff codes (8541.60.0050). Both are rated MSL 1 (Unlimited) for moisture sensitivity.

Q: What load capacitance should be used with the Fox Electronics substitute?

A: The Fox Electronics FC4SDCBMF12.0-T1 specifies 20pF load capacitance. Circuit design must accommodate this specification for proper frequency stability.

Q: Is RoHS compliance relevant for substitution?

A: The Fox Electronics substitute is ROHS3 Compliant. RoHS status was not provided for the original Crystek part and is not a substitution criterion based on the provided parameters.
