CD4510BPWE4 Equivalent & Substitute Parts

Part Overview

The CD4510BPWE4 is a BCD Counter IC manufactured by Texas Instruments, part of the 4000B logic series. This 4-bit counter integrates one element with positive edge triggering, asynchronous reset, and synchronous timing capabilities. The device operates across a wide supply voltage range of 3V to 18V and supports bidirectional counting (up/down). The CD4510BPWE4 is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4510BPWE4 is determined by strict equivalence across the following critical parameters:

• Logic Type: BCD Counter (identical functional classification)
• Number of Elements: 1 (single counter element)
• Number of Bits per Element: 4 (4-bit resolution)
• Direction: Up, Down (bidirectional counting capability)
• Reset Type: Asynchronous (reset behavior)
• Timing: Synchronous (clock synchronization method)
• Count Rate: 11 MHz (maximum operating frequency)
• Trigger Type: Positive Edge (clock edge sensitivity)
• Voltage - Supply: 3 V ~ 18 V (supply voltage range)
• Operating Temperature: -55°C ~ 125°C (thermal operating range)
• Package / Case: 16-TSSOP (physical form factor and pin compatibility)
• Mounting Type: Surface Mount (assembly method)

The CD4510BPWR is identified as the manufacturer-recommended substitute. Both parts share identical electrical specifications, thermal characteristics, and package geometry. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CD4510BPWR is the active equivalent for the obsolete CD4510BPWE4. Both parts maintain identical electrical and thermal specifications, ensuring functional interchangeability in circuit applications. The CD4510BPWR carries Active product status, providing long-term availability and supply chain continuity compared to the obsolete CD4510BPWE4.

Both parts comply with ROHS3 standards and carry REACH Unaffected status, meeting current environmental and regulatory requirements. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during assembly operations.

The packaging difference—Cut Tape & Digi-Reel® for the CD4510BPWE4 versus Tape & Reel for the CD4510BPWR—reflects standard distribution formats and does not affect electrical performance or pin compatibility. Selection between these formats depends on procurement volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD4510BPWR directly replace the CD4510BPWE4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Pin configuration, voltage ratings, operating frequency, and thermal range are equivalent. Direct substitution is supported without circuit modification.

Q: Why is the CD4510BPWE4 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The CD4510BPWR remains in active production and is the recommended replacement for new designs and ongoing production requirements.

Q: Are there differences in compliance or certifications between these parts?
