CD40192BCN Equivalent & Substitute Parts

Part Overview

The CD40192BCN is a decade counter integrated circuit from onsemi's 4000B logic series, designed for counting applications requiring up/down counting functionality. This 16-pin DIP package device performs as a 4-bit counter with synchronous timing and positive edge triggering. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD40192BCN is determined by strict equivalence across the following critical parameters:

Functional Requirements:

• Logic type must be Counter, Decade
• Bit configuration must be 4-bit per element
• Direction capability must support Up and Down counting
• Trigger type must be Positive Edge
• Reset function must be Asynchronous
• Timing must be Synchronous

Physical Requirements:

• Package must be 16-DIP (0.300", 7.62mm)
• Mounting type must be Through Hole

Electrical Requirements:

• Supply voltage range must encompass the operating range
• Operating temperature range must meet or exceed -55°C ~ 125°C

The CD40192BE from Harris Corporation meets all functional, physical, and electrical substitution criteria for the CD40192BCN.

Parameter Comparison

Engineering Selection Recommendations

The CD40192BE is a direct functional substitute for the CD40192BCN based on matching logic type, bit configuration, counting direction, trigger characteristics, package form factor, and operating temperature range. Both components are classified as obsolete products within the 4000B logic series.

The primary technical distinction is the maximum count rate specification: the CD40192BCN is rated at 12.5 MHz while the CD40192BE is rated at 5.5 MHz. In applications where the counter operates below 5.5 MHz, the CD40192BE provides full functional equivalence. In applications requiring operation above 5.5 MHz, the CD40192BE may not meet performance requirements.

The CD40192BE offers a wider supply voltage range (3 V ~ 18 V) compared to the CD40192BCN (3 V ~ 15 V), providing additional operational flexibility in systems with variable supply conditions.

Both components carry RoHS non-compliance status or unspecified compliance, consistent with their obsolete classification and legacy manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the CD40192BE replace the CD40192BCN in any application?

A: The CD40192BE is functionally equivalent for applications operating at count rates of 5.5 MHz or below. If your application requires count rates between 5.5 MHz and 12.5 MHz, the CD40192BE will not meet the performance specification of the original CD40192BCN.

Q: Are the pin configurations identical between these parts?

A: Both the CD40192BCN and CD40192BE use the 16-DIP package with 0.300" (7.62mm) spacing. Pin configuration and pinout are identical, allowing direct socket substitution without circuit board modification.

Q: What is the difference in supply voltage range between these parts?

A: The CD40192BCN operates from 3 V to 15 V, while the CD40192BE operates from 3 V to 18 V. The CD40192BE accommodates higher supply voltages, making it suitable for systems with supply rails up to 18 V.

Q: Are there RoHS compliance considerations for these substitutes?

A: Both the CD40192BCN and CD40192BE are non-compliant with RoHS standards. If your application requires RoHS-compliant components, neither of these obsolete logic ICs will satisfy that requirement.

Q: What mounting method do these components use?

A: Both parts are through-hole mounted devices in 16-DIP packages, requiring insertion into DIP sockets or direct soldering to PCB through-holes. No surface-mount alternatives are available within this product line.

Q: Can I use the CD40192BE if my circuit is designed for the CD40192BCN's 12.5 MHz specification?

A: No. If your circuit requires reliable operation at count rates above 5.5 MHz, the CD40192BE's lower maximum count rate specification makes it unsuitable. The component may not function reliably at the higher frequency.
