ADF4156BCPZ-RL Equivalent & Substitute Parts

Part Overview

The ADF4156BCPZ-RL is a Fractional N Synthesizer (RF) IC manufactured by Analog Devices Inc., designed for clock and timing applications requiring frequency synthesis up to 6.2GHz. This component integrates a phase-locked loop (PLL) with programmable divider and multiplier functionality, supporting CMOS and TTL inputs with clock outputs. The device is actively produced and ROHS3 compliant, making it suitable for modern electronic applications requiring precision frequency generation in the 2.7V to 3.3V supply range.

Equivalent and substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and functional characteristics while potentially differing in packaging format or inventory availability.

The substitute part ADF4156BCPZ-RL7 maintains complete electrical and mechanical equivalence to the primary part number. The difference lies exclusively in packaging format (Cut Tape and Digi-Reel® versus standard packaging) and inventory availability, with no impact on functional performance or circuit integration.

Parameter Comparison

Engineering Selection Recommendations

Both ADF4156BCPZ-RL and ADF4156BCPZ-RL7 are active products from Analog Devices Inc. with identical electrical and mechanical specifications. Selection between these part numbers should be based on procurement requirements and supply chain considerations rather than technical performance.

ADF4156BCPZ-RL7 offers higher inventory availability (6177 pieces) compared to ADF4156BCPZ-RL (893 pieces), making it suitable for high-volume production runs or applications requiring extended lead time assurance. The Cut Tape and Digi-Reel® packaging format of ADF4156BCPZ-RL7 supports automated assembly processes and reduces component handling costs in manufacturing environments.

Both variants maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for applications in regulated industries. The MSL rating of 3 (168 hours) applies uniformly across both part numbers, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can ADF4156BCPZ-RL7 be used as a direct replacement for ADF4156BCPZ-RL in existing designs?

A: Yes. Both part numbers are electrically and mechanically identical. They share the same 20-LFCSP (4x4) package footprint, supply voltage range (2.7V ~ 3.3V), operating temperature range (-40°C ~ 85°C), and functional specifications. The only difference is packaging format and inventory availability.

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

A: ADF4156BCPZ-RL7 is supplied in Cut Tape (CT) and Digi-Reel® packaging format, while ADF4156BCPZ-RL uses standard packaging. This distinction affects procurement logistics and automated assembly compatibility but does not impact electrical performance or circuit behavior.

Q: Are there any compliance or certification differences between these parts?

A: No. Both ADF4156BCPZ-RL and ADF4156BCPZ-RL7 carry identical certifications: ROHS3 compliance, REACH unaffected status, and MSL rating of 3 (168 hours). They are suitable for the same regulatory environments and applications.

Q: Which part number should be selected for new designs?

A: Selection should be based on supply chain and manufacturing requirements. ADF4156BCPZ-RL7 is recommended for high-volume production due to higher inventory availability and automated assembly compatibility through Cut Tape and Digi-Reel® packaging. ADF4156BCPZ-RL remains suitable for standard procurement workflows.

Q: Is the 20-WFQFN Exposed Pad, CSP package compatible with standard PCB assembly processes?

A: Yes. The 20-LFCSP (4x4) package is a standard surface mount package compatible with conventional reflow soldering and automated pick-and-place assembly equipment. The exposed pad design provides enhanced thermal performance and electrical connectivity.
