Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4015BNSR is determined by strict equivalence across the following critical parameters:

• Logic Function: Dual 4-bit shift register with serial-to-parallel conversion capability
• Element Configuration: 2 elements, 4 bits per element
• Output Architecture: Push-pull output type
• Pin Count and Package: 16-pin SOIC surface mount package
• Electrical Compatibility: Supply voltage range and operating temperature range must support the application requirements
• Compliance Standards: RoHS3 compliance and MSL rating

The HEF4015BT,653 manufactured by Nexperia USA Inc. meets these substitution criteria. Both devices share identical functional architecture, pin configuration, and core electrical characteristics within their respective operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The HEF4015BT,653 is the primary substitute for the obsolete CD4015BNSR. Both devices are ROHS3 compliant and carry MSL rating 1, meeting modern environmental and reliability standards.

The substitute part is currently in active production status, ensuring long-term availability and supply chain stability. The narrower supply voltage range of the HEF4015BT,653 (4.5V ~ 15.5V) compared to the CD4015BNSR (3V ~ 18V) requires verification against application-specific voltage requirements. The operating temperature range of the substitute (-40°C ~ 125°C) is narrower at the lower end but maintains the upper temperature specification.

Both devices are packaged in 16-SOIC surface mount configuration with identical pin assignments and functional behavior, supporting direct replacement in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the HEF4015BT,653 directly replace the CD4015BNSR in existing designs?

A: Yes, provided the application supply voltage operates within the HEF4015BT,653 range of 4.5V to 15.5V and the minimum operating temperature does not fall below -40°C. Both devices share identical pin configuration, logic function, and output characteristics.

Q: What is the primary difference between these two shift register devices?

A: The CD4015BNSR supports a wider supply voltage range (3V ~ 18V) and lower operating temperature limit (-55°C). The HEF4015BT,653 operates within 4.5V ~ 15.5V and -40°C ~ 125°C. Functional behavior and pin configuration are equivalent.

Q: Are there package dimension differences between the CD4015BNSR and HEF4015BT,653?

A: Both devices use 16-SOIC surface mount packaging. The CD4015BNSR package width is 5.30mm, while the HEF4015BT,653 package width is 3.90mm. Both are compatible with standard 16-SOIC PCB footprints.

Q: What compliance certifications apply to both devices?

A: Both the CD4015BNSR and HEF4015BT,653 are ROHS3 compliant and carry Moisture Sensitivity Level (MSL) rating 1, indicating unlimited shelf life under controlled storage conditions.

Q: Why is the CD4015BNSR classified as obsolete?

A: The CD4015BNSR is no longer in active production. The HEF4015BT,653 provides functional equivalence with active manufacturing status, ensuring continued availability for new designs and legacy system support.
