Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD40175BM are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Device Architecture: D-type flip-flop, single element, 4-bit configuration with positive edge triggering and complementary outputs
• Package Compatibility: 16-SOIC surface mount package with identical pinout and mechanical dimensions
• Electrical Performance: Clock frequency, propagation delay, supply voltage range, output current capability, and quiescent current
• Environmental Specifications: Operating temperature range and moisture sensitivity level
• Compliance: RoHS3 compliance and REACH status

Substitutes are grouped into two categories:

Category 1 - Texas Instruments Direct Substitutes: CD40175BM96 maintains identical electrical specifications and differs only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy).

Category 2 - Cross-Manufacturer Substitutes: MC14175BDG, MC14175BDR2G (onsemi), NLV14175BDR2G (onsemi), and HEF40175BT,653 (NXP Semiconductors) provide equivalent D-type flip-flop functionality within the 4000B series. These parts maintain core functional parameters but exhibit variations in output current, quiescent current, clock frequency, and propagation delay within acceptable engineering tolerances for the 4000B logic family.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - CD40175BM96: This Texas Instruments part is the recommended direct substitute. It maintains identical electrical specifications, operating temperature range, and RoHS3 compliance. The only difference is packaging format (Tape & Reel versus Tube) and active product status, making it suitable for immediate design migration and long-term supply assurance.

Secondary Substitutes - onsemi Parts (MC14175BDG, MC14175BDR2G, NLV14175BDR2G): These onsemi devices provide functional equivalence within the 4000B logic family. All three maintain the core D-type flip-flop architecture, 16-SOIC package, and full operating temperature range. Output current is increased to 8.8 mA and quiescent current rises to 20 µA compared to the CD40175BM. These parts are suitable for applications where the increased output drive capability is beneficial or where higher quiescent current is acceptable. All three are active products with RoHS3 compliance.

Alternative Substitute - HEF40175BT,653: The NXP Semiconductors HEF40175BT,653 offers enhanced performance with 45 MHz clock frequency and 45 ns propagation delay, representing a 3.2x speed improvement over the CD40175BM. Output current is reduced to 3.4 mA. The supply voltage range is constrained to 3V to 15V (versus 3V to 18V for the CD40175BM), and the operating temperature minimum is -40°C (versus -55°C). This part is suitable for applications requiring higher speed performance where the voltage and temperature constraints are acceptable.

Selection Criteria: Choose CD40175BM96 for direct replacement in existing designs. Select onsemi alternatives when increased output current or cross-manufacturer sourcing is required. Consider HEF40175BT,653 only when higher speed performance justifies the reduced voltage range and temperature operating window.

Frequently Asked Questions (FAQ)

Q: Can CD40175BM96 be used as a direct replacement for CD40175BM?

A: Yes. CD40175BM96 is electrically and mechanically identical to CD40175BM. The only differences are packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy). Pinout, electrical specifications, and performance characteristics are identical.

Q: What are the key differences between Texas Instruments and onsemi substitutes?

A: Texas Instruments CD40175BM and CD40175BM96 specify 6.8 mA output current and 4 µA quiescent current. onsemi parts (MC14175BDG, MC14175BDR2G, NLV14175BDR2G) increase output current to 8.8 mA and quiescent current to 20 µA. All maintain identical clock frequency (14 MHz), propagation delay (120 ns), and package configuration. The increased output current in onsemi devices provides greater drive capability for downstream logic loads.

Q: Is the HEF40175BT,653 a suitable substitute for all applications?

A: The HEF40175BT,653 is suitable only for applications where the reduced supply voltage range (3V to 15V versus 3V to 18V) and reduced operating temperature minimum (-40°C versus -55°C) are acceptable. This part offers superior speed performance (45 MHz, 45 ns propagation delay) but reduced output current (3.4 mA). Verify design requirements before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: CD40175BM96, MC14175BDG, MC14175BDR2G, and NLV14175BDR2G are confirmed RoHS3 compliant. HEF40175BT,653 RoHS status is not specified in the provided data. Verify compliance documentation with the supplier if RoHS3 certification is a design requirement.

Q: What packaging options are available for each substitute?

A: CD40175BM is supplied in Tube packaging. CD40175BM96 is available in Tape & Reel format. MC14175BDG is supplied in Tube. MC14175BDR2G and NLV14175BDR2G are available in Tape & Reel. HEF40175BT,653 is supplied in Bulk format. Select packaging based on production volume and assembly process requirements.

Q: Can onsemi and NXP parts be mixed in the same design?

A: All substitute parts maintain identical 16-SOIC pinout and D-type flip-flop functionality. However, mixing manufacturers in the same design introduces variations in output current, quiescent current, and performance characteristics. For consistency, standardize on a single manufacturer within a design unless application requirements specifically justify mixed sourcing.

Q: What is the MSL rating for all parts?

A: All listed parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures are sufficient for all parts.
