CD4510BCN Equivalent & Substitute Parts

Part Overview

The CD4510BCN is a BCD counter IC from the 4000B logic series manufactured by onsemi. This component functions as a 4-bit binary-coded decimal counter with up/down counting capability. The CD4510BCN is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence in BCD counter operation while meeting current component availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4510BCN is determined by the following core parameters:

• Logic Type: BCD Counter (4-bit binary-coded decimal counter function)
• Direction: Up/Down counting capability
• Series: 4000B logic family
• Base Product Number: CD4510 (core functional designation)

The CD4510BE from Texas Instruments qualifies as a direct substitute based on matching these parameters. Both parts share the same base product number (CD4510), operate as BCD counters with bidirectional counting, and belong to the 4000B series. The substitute maintains functional equivalence for BCD counter applications requiring up/down counting operation.

Engineering Selection Recommendations

The CD4510BE from Texas Instruments is the qualified substitute for the obsolete CD4510BCN. Selection of the CD4510BE is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance meets current environmental and regulatory requirements, whereas the CD4510BCN is RoHS non-compliant
• Both parts maintain REACH Unaffected status and EAR99 export classification
• Functional equivalence is established through matching BCD counter logic type, bidirectional counting capability, and 4000B series designation

For applications requiring RoHS compliance or long-term component availability, the CD4510BE is the appropriate selection. Existing designs using the CD4510BCN can transition to the CD4510BE while maintaining functional compatibility within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: What makes CD4510BE a valid substitute for CD4510BCN?

A: Both parts share the same base product number (CD4510), function as 4-bit BCD counters with up/down counting capability, and belong to the 4000B logic series. These core parameters define functional equivalence for BCD counter applications.

Q: Are there package differences between CD4510BCN and CD4510BE?

A: The CD4510BE is specified in 16-DIP (0.300", 7.62mm) through-hole packaging. Package information for the CD4510BCN is not provided in the available data. Pin compatibility should be verified against the specific package variant of the CD4510BCN in use.

Q: What is the significance of the RoHS compliance difference?

A: The CD4510BCN is RoHS non-compliant, while the CD4510BE is ROHS3 compliant. For new designs and applications subject to RoHS regulations, the CD4510BE meets current environmental standards. Existing legacy systems may continue using RoHS non-compliant components if regulatory requirements do not apply.

Q: Why is the CD4510BCN listed as obsolete?

A: Obsolete status indicates the CD4510BCN is no longer in active production. The CD4510BE provides continuity for applications requiring BCD counter functionality with active product support and current compliance certifications.

Q: Can CD4510BE be used in all applications previously using CD4510BCN?

A: Functional substitution is valid for applications requiring BCD counter operation with up/down counting. Electrical parameters such as supply voltage range (3 V ~ 18 V) and operating temperature range (-55°C ~ 125°C) for the CD4510BE should be verified against the specific application requirements.
