CD4511BNSRG4 Equivalent & Substitute Parts

Part Overview

The CD4511BNSRG4 is an LED driver integrated circuit designed for 7-segment display applications. It converts BCD (Binary Coded Decimal) input signals into the appropriate output levels required to drive 7-segment LED displays. The device operates across a wide supply voltage range of 3V to 18V and maintains low supply current consumption of 40 nA, making it suitable for battery-powered and low-power applications.

The CD4511BNSRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, maintenance, and new implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4511BNSRG4 is determined by strict equivalence across the following critical parameters:

• Display Type & Configuration: Both main and substitute parts must support LED 7-segment display driving
• Interface Protocol: BCD input interface must be maintained
• Electrical Specifications: Supply voltage range (3V ~ 18V), supply current (40 nA), and operating temperature range (-55°C ~ 125°C) must be identical
• Package Compatibility: 16-SOIC surface mount package with 0.209" (5.30mm) width ensures PCB layout compatibility
• Compliance & Certifications: ROHS3 compliance, MSL rating, and REACH status must match

The CD4511BNSR meets all these criteria and qualifies as a direct substitute for the CD4511BNSRG4.

Parameter Comparison

Engineering Selection Recommendations

The CD4511BNSR is the qualified substitute for the CD4511BNSRG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the CD4511BNSRG4 is discontinued, while the CD4511BNSR remains in active production with significantly higher inventory availability (19,190 units versus 945 units).

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. The identical package footprint (16-SOIC) and electrical parameters guarantee direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the CD4511BNSR be used as a direct replacement for the CD4511BNSRG4?

A: Yes. Both parts are electrically and mechanically identical. They share the same BCD-to-7-segment interface, supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and 16-SOIC package footprint. No circuit modifications are required.

Q: What is the difference between CD4511BNSRG4 and CD4511BNSR?

A: The primary difference is product status and packaging format. The CD4511BNSRG4 is discontinued, while the CD4511BNSR is active. The CD4511BNSR is available in Cut Tape (CT) and Digi-Reel® packaging options, providing greater supply chain flexibility.

Q: Are there any compliance or certification differences?
