Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7W-16.384MBD-T are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Frequency: 16.384 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

Mechanical Parameters:

• Mounting Type: Surface Mount (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 7.00mm x 5.00mm (exact match required)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• ECCN: EAR99 (exact match required)
• HTSUS: 8542.39.0001 (exact match required)

All three substitute parts meet these critical parameters. Variations in maximum supply current, disable current, and seated height do not affect substitution eligibility, as these parameters remain within acceptable operational ranges for the intended application.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally and mechanically compatible with the 7W-16.384MBD-T based on provided specifications. Selection among these alternatives should be based on the following factors:

Product Status & Supply Continuity: All substitute parts carry Active product status, ensuring long-term availability and ongoing manufacturer support. The main part (7W-16.384MBD-T) is Obsolete, making substitution necessary for future procurement.

Compliance & Certifications:

• 510CBA16M3840AAGR (Skyworks Solutions Inc.): RoHS status not specified in provided data
• CPPC7L-A7BR-16.384TS (Cardinal Components Inc.): ROHS3 Compliant
• CPPFXC7LZ-A7BR-16.384TS (Cardinal Components Inc.): ROHS3 Compliant

Both Cardinal Components parts provide explicit ROHS3 compliance certification, which may be required for applications subject to RoHS3 regulations.

Physical Dimensions: The main part has a maximum seated height of 0.056" (1.42mm). All substitute parts have greater seated heights (0.071" to 0.075"), which must be evaluated against PCB layout constraints and available vertical clearance in the target application.

Current Consumption: The main part specifies 20mA maximum supply current. Substitute parts range from 25mA to 26mA maximum supply current. This increase must be evaluated against power supply capacity and thermal design margins.

Inventory Availability: CPPFXC7LZ-A7BR-16.384TS and 7W-16.384MBD-T both show 1032 Pcs in stock, providing equivalent availability. 510CBA16M3840AAGR shows 914 Pcs, and CPPC7L-A7BR-16.384TS shows 718 Pcs.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA16M3840AAGR directly replace the 7W-16.384MBD-T?

A: Yes. The 510CBA16M3840AAGR meets all critical electrical and mechanical parameters: 16.384 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, ±25ppm stability, -40°C to 85°C operating range, 4-SMD No Lead package, and 7.00mm x 5.00mm dimensions. The maximum supply current increases from 20mA to 26mA, which is within acceptable operational margins for most applications.

Q: What is the difference between CPPC7L-A7BR-16.384TS and CPPFXC7LZ-A7BR-16.384TS?

A: Both parts are manufactured by Cardinal Components Inc. and share identical electrical specifications. The primary difference is the series designation: CPPC7L belongs to the FIPO™ CPP series, while CPPFXC7LZ belongs to the FIPO™ CPPFX series. Both are ROHS3 compliant and functionally equivalent for the 16.384 MHz CMOS oscillator application.

Q: Are there height differences that affect PCB layout?

A: Yes. The main part (7W-16.384MBD-T) has a maximum seated height of 0.056" (1.42mm). The Skyworks part (510CBA16M3840AAGR) measures 0.071" (1.80mm), and both Cardinal Components parts measure 0.075" (1.90mm). These differences must be evaluated against available vertical clearance on the PCB and any components or enclosures in proximity to the oscillator.

Q: Which substitute part offers the best RoHS compliance?

A: Both CPPC7L-A7BR-16.384TS and CPPFXC7LZ-A7BR-16.384TS explicitly state ROHS3 compliance. The 510CBA16M3840AAGR does not specify RoHS status in the provided data. For applications requiring documented ROHS3 compliance, either Cardinal Components part is the appropriate selection.

Q: What is the impact of increased supply current on power design?

A: The substitute parts draw 25mA to 26mA maximum supply current, compared to 20mA for the main part. This represents a 5mA to 6mA increase. Power supply capacity and current delivery capability must be verified to accommodate this increase. Thermal design margins should be re-evaluated if the oscillator operates continuously at maximum current.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All three substitute parts are specified with Tape & Reel (TR) packaging, suitable for automated assembly processes. The main part packaging format is not specified in the provided data.

Q: Can I use these parts interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification of PCB layout constraints, particularly regarding the increased seated height of substitute parts. Pin configuration and signal timing must be confirmed to match the original design requirements.
