CDCEL925PWRG4 Equivalent & Substitute Parts

Part Overview

The CDCEL925PWRG4 is a Clock/Frequency Synthesizer IC manufactured by Texas Instruments, designed for applications requiring programmable clock generation and frequency synthesis up to 230MHz. This device features a Phase-Locked Loop (PLL) with bypass capability, LVCMOS input and output, and operates across the industrial temperature range of -40°C to 85°C in a 16-TSSOP surface mount package.

The CDCEL925PWRG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDCEL925PWRG4 is determined by strict equivalence across the following critical parameters:

• Frequency Performance: Maximum frequency of 230MHz
• PLL Architecture: Phase-Locked Loop with bypass capability
• Signal Interface: LVCMOS input (supporting both LVCMOS and Crystal sources) and LVCMOS output
• Frequency Ratio: 1:5 input-to-output ratio
• Supply Voltage: 1.7V to 1.9V operating range
• Temperature Range: -40°C to 85°C industrial specification
• Package Form Factor: 16-TSSOP surface mount package with 0.173" width and 4.40mm body width
• Compliance: ROHS3 compliance and MSL Level 1 rating

The CDCEL925PWR meets all these criteria and is classified as the manufacturer-recommended substitute. The primary distinction between the main part and substitute is packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The CDCEL925PWR is the direct functional equivalent of the CDCEL925PWRG4 and is designated as the manufacturer-recommended substitute by Texas Instruments. Both parts share identical electrical specifications, thermal characteristics, and mechanical form factors.

The CDCEL925PWR is currently in active production status, whereas the CDCEL925PWRG4 is discontinued. For new designs and ongoing production requirements, the CDCEL925PWR is the appropriate selection. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

The packaging difference (Digi-Reel® versus Tape & Reel) does not affect electrical performance or board-level integration. Selection between these packaging options depends on procurement volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can the CDCEL925PWR be used as a direct replacement for the CDCEL925PWRG4?

A: Yes. The CDCEL925PWR is electrically and mechanically identical to the CDCEL925PWRG4. Both devices share the same base product number (CDCEL925), identical frequency specifications (230MHz maximum), matching PLL architecture with bypass, and the same 16-TSSOP package form factor. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between the CDCEL925PWRG4 and CDCEL925PWR?

A: The primary differences are product status and packaging configuration. The CDCEL925PWRG4 is discontinued at DiGi Electronics and supplied in Digi-Reel® packaging, while the CDCEL925PWR is in active production and supplied in standard Tape & Reel (TR) packaging. All electrical and thermal specifications are identical.

Q: Are there any compatibility concerns when substituting the CDCEL925PWR for the CDCEL925PWRG4?

A: No compatibility concerns exist. Both parts operate across the same supply voltage range (1.7V to 1.9V), support identical input types (LVCMOS and Crystal), and produce LVCMOS output signals. The 16-TSSOP package dimensions and pin assignments are identical, ensuring direct PCB compatibility.

Q: Does the packaging difference affect performance or reliability?

A: No. Tape & Reel (TR) and Digi-Reel® packaging formats provide equivalent protection and handling characteristics. The difference is administrative and relates to procurement and assembly line processing. Electrical performance and reliability are unaffected.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDCEL925PWRG4 and CDCEL925PWR are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and regulatory requirements.
