CD4515BE Equivalent & Substitute Parts

Part Overview

The CD4515BE is a decoder/demultiplexer integrated circuit from Texas Instruments' 4000B logic series, configured as a 1 x 4:16 decoder in a 24-pin DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The CD4515BE operates with dual supply voltage ranging from 3V to 18V and supports operating temperatures from -55°C to 125°C, making it suitable for industrial and extended-temperature applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4515BE is determined by functional equivalence across the following critical parameters:

• Decoder/Demultiplexer Configuration: 1 x 4:16 circuit topology
• Output Current Specifications: 6.8mA high and low output current
• Voltage Supply Requirements: Dual supply operation within 3V to 18V range
• Operating Temperature Range: -55°C to 125°C capability
• Base Product Number: CD4515 series designation
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The CD4515BM96 qualifies as a manufacturer-recommended substitute because it maintains identical electrical specifications and functional performance while differing only in packaging format (24-SOIC surface mount versus 24-DIP through hole) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The CD4515BM96 is the manufacturer-recommended substitute for the obsolete CD4515BE. Both components maintain identical electrical performance specifications, including output current, supply voltage range, and operating temperature capabilities. The primary distinction is packaging format: the CD4515BE uses through-hole 24-DIP mounting, while the CD4515BM96 uses surface-mount 24-SOIC technology.

Selection between these parts depends on board assembly requirements. The CD4515BM96 is preferred for new designs due to its active product status and surface-mount compatibility with modern manufacturing processes. The CD4515BE remains available for legacy system repairs or through-hole board designs where surface-mount conversion is not feasible.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the CD4515BM96 directly replace the CD4515BE in existing designs?

A: Electrical substitution is complete; however, physical board layout modification is required. The CD4515BE uses through-hole 24-DIP mounting, while the CD4515BM96 uses surface-mount 24-SOIC technology. PCB footprint redesign is necessary for implementation.

Q: Are the output current specifications identical between these parts?

A: Yes. Both the CD4515BE and CD4515BM96 provide 6.8mA output current for high and low states, maintaining identical drive capability.

Q: What is the voltage supply compatibility range for both parts?

A: Both parts operate with dual supply voltage from 3V to 18V. Supply voltage specifications are identical across the product line.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the CD4515BE and CD4515BM96 operate across -55°C to 125°C, supporting industrial and extended-temperature applications.

Q: Are there compliance differences between the CD4515BE and CD4515BM96?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the CD4515BE classified as obsolete?

A: The CD4515BE represents legacy through-hole technology. The CD4515BM96 surface-mount variant reflects current manufacturing standards and remains in active production.
