Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDCE925PWRG4 is determined by strict equivalence across the following critical parameters:

• Frequency Specification: Maximum output frequency of 230MHz
• Input/Output Configuration: LVCMOS and Crystal input support with LVCMOS output
• Multiplier Ratio: 1:5 input-to-output ratio
• Supply Voltage Range: 1.7V ~ 1.9V operation
• Package Type: 16-TSSOP surface mount package
• Temperature Range: -40°C ~ 85°C operating window
• Regulatory Compliance: ROHS3 and REACH compliance status

The CDCE925PWR meets all these criteria and is classified as the manufacturer-recommended substitute. Both parts share the same base product number (CDCE925) and are functionally equivalent across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CDCE925PWR is the direct substitute for the CDCE925PWRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the CDCE925PWRG4 is discontinued, while the CDCE925PWR remains in active production with higher inventory availability (6740 units versus 1299 units).

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The CDCE925PWR is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for production volumes.

Frequently Asked Questions (FAQ)

Q: Are CDCE925PWRG4 and CDCE925PWR pin-for-pin compatible?

A: Yes. Both parts use the 16-TSSOP package with identical pinout and electrical characteristics. Direct substitution is possible without circuit modification.

Q: What is the difference between these two part numbers?

A: The CDCE925PWRG4 and CDCE925PWR are functionally equivalent. The suffix variation reflects different manufacturing batches or packaging configurations. The CDCE925PWR is the active production part.

Q: Can I use CDCE925PWR in applications originally designed for CDCE925PWRG4?

A: Yes. All electrical parameters, frequency specifications, supply voltage ranges, and operating temperature ranges are identical. The parts are direct replacements.

Q: What packaging options are available for the substitute part?

A: The CDCE925PWR is supplied in Cut Tape (CT) and Digi-Reel packaging formats, suitable for both manual and automated assembly processes.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1) is the same for both.

Q: Why is the original part discontinued?

A: Product discontinuation typically reflects manufacturing transitions or market consolidation. The CDCE925PWR remains the active equivalent and is the recommended replacement.
