Substitute Part Grouping Explanation

Substitution of the CD40175BEG4 is determined by strict equivalence across the following critical parameters:

• Functional Architecture: D-type flip-flop with 1 element, 4 bits per element, positive edge trigger, complementary outputs, and master reset function
• Electrical Specifications: Clock frequency of 14 MHz, propagation delay of 120 ns @ 15V/50pF, supply voltage range of 3V ~ 18V, output current of 6.8mA (high and low), quiescent current of 4 µA, and input capacitance of 5 pF
• Package Compatibility: 16-DIP (0.300", 7.62mm) through-hole mounting
• Series Classification: 4000B logic family

The CD40175BE manufactured by Harris Corporation meets all electrical and mechanical requirements for direct substitution. Both parts share identical functional specifications, electrical performance characteristics, and physical packaging, enabling pin-for-pin replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The CD40175BE from Harris Corporation is the primary equivalent substitute for the CD40175BEG4. Both components are functionally and electrically identical across all specified parameters, enabling direct pin-for-pin replacement.

Compliance Consideration: The original CD40175BEG4 is ROHS3 compliant, while the CD40175BE is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, this distinction must be evaluated against system-level compliance obligations. The CD40175BE remains electrically and mechanically suitable for applications where RoHS compliance is not mandated.

Product Status: Both parts are discontinued or obsolete, indicating limited availability through standard distribution channels. Sourcing decisions should account for inventory status and long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the CD40175BE directly replace the CD40175BEG4 in existing designs?

A: Yes. The CD40175BE is a pin-for-pin equivalent with identical electrical specifications, functional architecture, and 16-DIP package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between the CD40175BEG4 and CD40175BE?

A: The primary differences are manufacturer (Texas Instruments vs. Harris Corporation), RoHS compliance status (ROHS3 compliant vs. non-compliant), and product status (discontinued vs. obsolete). Electrical and mechanical specifications are identical.

Q: Are there any performance differences between these parts?

A: No. Both components share identical clock frequency (14 MHz), propagation delay (120 ns @ 15V, 50pF), supply voltage range (3V ~ 18V), output current (6.8mA), quiescent current (4 µA), and operating temperature range (-55°C ~ 125°C).

Q: Does the RoHS non-compliance of the CD40175BE affect its functionality?

A: RoHS compliance status does not affect electrical performance or functionality. It reflects manufacturing process and material composition. Applications not subject to RoHS regulations can use the CD40175BE without functional impact.

Q: What packaging options are available for these parts?

A: Both the CD40175BEG4 and CD40175BE are supplied in 16-DIP (0.300", 7.62mm) through-hole packages. No alternative package options are specified for these part numbers.

Q: Can these parts be used in new designs?

A: Both parts are discontinued or obsolete, limiting availability for new production. Component selection for new designs should consider long-term sourcing viability and explore alternative logic families if extended product lifecycles are required.
