Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7W16370002 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

• Package Type: 4-SMD, No Lead
• Footprint Dimensions: 7.00mm x 5.00mm
• Mounting: Surface Mount

All three substitute parts listed below meet these equivalence criteria. Substitutes are grouped as direct functional replacements with identical electrical performance and mechanical compatibility. The primary differentiator among substitutes is product status (Active vs. Obsolete) and current supply specifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

All three substitute parts are functionally equivalent to the 7W16370002 and are suitable for direct replacement. Selection among substitutes should be based on the following factors:

510CBA16M3840AAGR (Skyworks Solutions Inc.):

• Active product status with ongoing manufacturer support
• Specified current supply characteristics (26mA active, 18mA disabled)
• Slightly elevated seated height (1.80mm) compared to original specification
• Suitable for applications where Skyworks component qualification is required

CPPC7L-A7BR-16.384TS (Cardinal Components Inc.):

• Active product status with ongoing manufacturer support
• ROHS3 Compliant certification
• Lower disable current consumption (50µA) compared to Skyworks alternative
• Maximum seated height of 1.90mm
• Suitable for applications requiring enhanced RoHS compliance documentation

CPPFXC7LZ-A7BR-16.384TS (Cardinal Components Inc.):

• Active product status with ongoing manufacturer support
• ROHS3 Compliant certification
• Identical electrical and mechanical specifications to CPPC7L-A7BR-16.384TS
• FIPO™ CPPFX series designation indicates enhanced feature set
• Maximum seated height of 1.90mm
• Suitable for applications requiring enhanced RoHS compliance documentation

Height Consideration: The original 7W16370002 specifies a maximum seated height of 1.42mm. All substitute parts exceed this specification (1.80mm to 1.90mm). PCB layout and component clearance must be verified before substitution in space-constrained applications.

Compliance Consideration: The original part carries RoHS Compliant status. Both Cardinal Components substitutes carry ROHS3 Compliant status, representing enhanced regulatory compliance. The Skyworks substitute does not specify RoHS status in provided documentation.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA16M3840AAGR directly replace the 7W16370002 in existing designs?

A: The 510CBA16M3840AAGR is electrically and mechanically equivalent for the specified operating parameters. However, the seated height increases from 1.42mm to 1.80mm. PCB layout clearance must be verified to confirm compatibility with existing designs.

Q: What is the primary difference between the two Cardinal Components substitutes?

A: Both CPPC7L-A7BR-16.384TS and CPPFXC7LZ-A7BR-16.384TS share identical electrical specifications and mechanical dimensions. The CPPFXC7LZ variant belongs to the FIPO™ CPPFX series, indicating a different product line within Cardinal's oscillator portfolio. Selection between these two should be based on component availability and design qualification requirements.

Q: Are all substitute parts RoHS compliant?

A: The Cardinal Components substitutes (CPPC7L-A7BR-16.384TS and CPPFXC7LZ-A7BR-16.384TS) carry ROHS3 Compliant certification. The Skyworks substitute (510CBA16M3840AAGR) does not specify RoHS status in the provided documentation. For applications with mandatory RoHS compliance requirements, Cardinal Components substitutes are recommended.

Q: What is the impact of increased seated height on PCB design?

A: The original 7W16370002 specifies 1.42mm maximum seated height. Substitute parts range from 1.80mm to 1.90mm. This 0.38mm to 0.48mm increase may affect component clearance in designs with tight vertical spacing constraints, particularly in multi-layer PCB assemblies or applications with low-profile enclosures. PCB layout review is required before substitution.

Q: Which substitute offers the lowest power consumption in disabled mode?

A: Both Cardinal Components substitutes (CPPC7L-A7BR-16.384TS and CPPFXC7LZ-A7BR-16.384TS) specify 50µA maximum disable current, significantly lower than the Skyworks substitute at 18mA. For battery-powered or low-power applications where the oscillator is frequently disabled, Cardinal Components substitutes provide superior power efficiency.

Q: Is the 7W16370002 still available for procurement?

A: The 7W16370002 carries Obsolete product status. While inventory may exist through component distributors, long-term availability is not assured. Transition to an active substitute part is recommended for new procurement and design continuity.

Q: Can substitute parts be mixed in the same production batch?

A: All three substitute parts meet identical electrical and mechanical specifications for the critical parameters. However, mixing different manufacturers or series in the same production batch may complicate supply chain management and traceability. Standardization on a single substitute part is recommended for manufacturing consistency.
