CD4098BE-NG Equivalent & Substitute Parts

Part Overview

The CD4098BE-NG is a monostable multivibrator logic integrated circuit manufactured by Texas Instruments, belonging to the 4000B series. This device features dual independent circuits with 100 ns propagation delay and Schmitt trigger input capability, housed in a 16-pin DIP package for through-hole mounting applications.

The CD4098BE-NG is classified as an obsolete product. Locating equivalent substitute parts is necessary for ongoing system maintenance, design updates, and procurement continuity when original inventory becomes unavailable or when transitioning to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4098BE-NG is determined by the following critical parameters:

Core Functional Parameters:

• Logic type: Monostable multivibrator
• Independent circuits: 2
• Propagation delay: 100 ns
• Supply voltage range: 3 V ~ 18 V
• Output current capability: 6.8 mA (high and low)
• Operating temperature range: -55°C ~ 125°C
• Manufacturer series: 4000B (Texas Instruments)

Compliance Requirements:

• RoHS3 compliance status
• Base product number: CD4098

The CD4098BPWR substitute maintains electrical equivalence across all functional parameters while offering an active product status and surface-mount packaging alternative. Both devices share identical logic specifications, supply voltage tolerance, output current ratings, and temperature operating range, enabling direct functional substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Functional Equivalence: The CD4098BPWR provides complete electrical equivalence to the CD4098BE-NG. Both devices deliver identical logic performance, timing characteristics, and electrical specifications across the full operating range.

Product Status Consideration: The CD4098BE-NG is classified as obsolete, while the CD4098BPWR maintains active product status with Texas Instruments. Active product designation ensures ongoing availability, manufacturing support, and compliance maintenance.

Compliance Status: Both parts maintain ROHS3 compliance certification, satisfying regulatory requirements for new designs and system updates.

Packaging and Mounting Transition: The primary difference between these devices is packaging format. The CD4098BE-NG uses through-hole 16-DIP mounting, while the CD4098BPWR employs surface-mount 16-TSSOP technology. This transition requires PCB layout modification and assembly process adjustment but does not affect electrical functionality or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the CD4098BPWR directly replace the CD4098BE-NG in existing circuit designs?

A: Electrical substitution is complete. The CD4098BPWR maintains identical logic specifications, timing parameters, and electrical characteristics. However, physical substitution requires PCB redesign due to different package formats (through-hole DIP versus surface-mount TSSOP).

Q: What are the key differences between these two parts?

A: The devices are electrically identical across all functional parameters. The primary differences are: (1) mounting technology—through-hole versus surface-mount; (2) package dimensions—16-DIP (0.300" width) versus 16-TSSOP (0.173" width); (3) product status—obsolete versus active.

Q: Does the CD4098BPWR include Schmitt trigger input capability?

A: The CD4098BE-NG includes Schmitt trigger input functionality. The CD4098BPWR does not feature Schmitt trigger input. If Schmitt trigger input is a critical circuit requirement, functional equivalence cannot be confirmed.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD4098BE-NG and CD4098BPWR maintain ROHS3 compliance certification.

Q: What is the moisture sensitivity level of the CD4098BPWR?

A: The CD4098BPWR carries MSL rating 1 (Unlimited), indicating minimal moisture sensitivity and standard handling requirements.

Q: Which part should be selected for new designs?

A: The CD4098BPWR is the appropriate selection for new designs. It maintains active product status, ensuring long-term availability and manufacturing continuity. The CD4098BE-NG, being obsolete, is suitable only for legacy system maintenance or replacement applications.
