CD4048BCN Equivalent & Substitute Parts

Part Overview

The CD4048BCN is an expandable 8-input gate logic integrated circuit manufactured by onsemi in the 4000B series. This multifunction expandable configurable device features a single circuit with 8 inputs and single-ended output, housed in a 14-DIP (0.300", 7.62mm) package for through-hole mounting. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the CD4048BCN is based on functional equivalence within the 4000B CMOS logic family. The primary substitution criterion is the preservation of core logic functionality: multifunction expandable configuration with 8 inputs and single-ended output. Both the main part and substitute maintain identical logic type, circuit count, input count, and output characteristics. Through-hole mounting compatibility is maintained across all alternatives. Package differences (14-DIP versus 16-DIP) are acceptable provided the pinout and electrical function remain equivalent and the substitute can be accommodated within the physical constraints of the application.

Engineering Selection Recommendations

The CD4048BE from Harris Corporation is a direct functional equivalent to the CD4048BCN. Both devices are obsolete products within the 4000B CMOS logic family with identical core specifications: single multifunction expandable circuit, 8 inputs, and single-ended output. The primary consideration for selection is package accommodation: the CD4048BE uses a 16-DIP package compared to the 14-DIP of the CD4048BCN. Both maintain through-hole mounting compatibility and identical pitch (0.300", 7.62mm). The CD4048BE provides specified electrical parameters (6.8mA output current, 3V–18V supply voltage range, -55°C–125°C operating temperature), whereas the CD4048BCN does not include these specifications in the available data. Both devices carry identical export classification (EAR99) and RoHS non-compliance status. Selection should be based on PCB layout constraints and package footprint availability within the application.

Frequently Asked Questions (FAQ)

Q: Can the CD4048BE directly replace the CD4048BCN without circuit modification?

A: Functional replacement is possible provided the 16-DIP package footprint can be accommodated on the PCB. The core logic function, input/output configuration, and electrical characteristics are equivalent. Pinout verification against the specific application schematic is required.

Q: What is the primary difference between the CD4048BCN and CD4048BE?

A: The main difference is the package configuration: CD4048BCN uses 14-DIP while CD4048BE uses 16-DIP. Both maintain 0.300" (7.62mm) pitch for through-hole mounting. The CD4048BE provides documented electrical specifications that are not available for the CD4048BCN.

Q: Are both parts RoHS compliant?

A: No. Both the CD4048BCN and CD4048BE are classified as RoHS non-compliant. If RoHS compliance is required for the application, alternative components from current product lines must be evaluated.

Q: What is the moisture sensitivity level for these parts?

A: The CD4048BCN has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Can these obsolete parts be sourced for new designs?

A: Both devices are obsolete. Availability is limited to existing inventory from authorized distributors. For new designs, evaluation of current-generation CMOS logic alternatives within the 4000 series or modern equivalents is recommended.
