CD4528BCN Equivalent & Substitute Parts

Part Overview

The CD4528BCN is a monostable multivibrator logic IC manufactured by onsemi, housed in a 16-DIP package. This component features two independent circuits with a 65 ns propagation delay and operates across a wide supply voltage range of 3 V to 15 V. The CD4528BCN is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4528BCN is determined by the following critical parameters:

• Logic Type: Monostable multivibrator functionality
• Independent Circuits: 2 circuits per package
• Package / Case: 16-DIP form factor with 0.300" (7.62mm) pitch
• Mounting Type: Through hole configuration
• Voltage - Supply Range: Minimum 3 V operation with upper limit compatibility
• Operating Temperature Range: -55°C ~ 125°C support
• Series Compatibility: 4000B logic family

The CD4098BE qualifies as a direct substitute based on matching logic type, circuit count, package format, and temperature range. The CD4017BE, while sharing the same package and series, functions as a decade counter rather than a monostable multivibrator and therefore serves a different application purpose.

Parameter Comparison

Engineering Selection Recommendations

CD4098BE is the primary substitute for CD4528BCN applications. Both components are monostable multivibrators with two independent circuits in identical 16-DIP packages. The CD4098BE offers an extended supply voltage range (3 V ~ 18 V versus 3 V ~ 15 V) and maintains the same operating temperature specification. The propagation delay difference of 35 ns (CD4098BE at 100 ns versus CD4528BCN at 65 ns) must be evaluated against circuit timing requirements. The CD4098BE holds Active product status and ROHS3 compliance, providing better long-term availability and regulatory alignment compared to the obsolete CD4528BCN.

CD4017BE shares the same package and series but functions as a decade counter. This part is not suitable as a direct substitute due to fundamentally different logic functionality, despite package compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD4098BE directly replace CD4528BCN in existing designs?

A: CD4098BE is functionally compatible as a monostable multivibrator substitute. Both components feature two independent circuits, identical 16-DIP packaging, and matching temperature ranges. The 35 ns propagation delay difference must be verified against circuit timing specifications before implementation.

Q: What is the significance of the propagation delay difference?

A: Propagation delay determines the speed at which the multivibrator responds to input signals. CD4528BCN operates at 65 ns while CD4098BE operates at 100 ns. Applications with strict timing requirements must confirm that the slower response time of CD4098BE does not affect circuit performance.

Q: Why is CD4017BE listed if it cannot substitute for CD4528BCN?

A: CD4017BE is a decade counter with different logic functionality. While it shares the same 16-DIP package and 4000B series classification, it cannot perform monostable multivibrator functions. It is included for reference to clarify substitution boundaries.

Q: Are there packaging alternatives to 16-DIP for these components?

A: The specifications provided cover only 16-DIP through-hole packages. Alternative package formats are not included in this reference.

Q: What compliance advantages does CD4098BE offer?

A: CD4098BE is ROHS3 compliant and maintains Active product status, ensuring continued availability and regulatory compliance. CD4528BCN is obsolete with unspecified RoHS status, making CD4098BE preferable for new designs and long-term supply chain stability.
