Substitute Part Grouping Explanation

Substitution of the CD4078BM is determined by strict equivalence across the following critical parameters:

• Logic Type: NOR/OR Gate configuration
• Number of Circuits: 1
• Number of Inputs: 8
• Output Type: Single-Ended
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Electrical Characteristics: Current output (6.8mA high/low), supply voltage range (3V ~ 18V), operating temperature (-55°C ~ 125°C)
• Compliance: RoHS3 compliance, MSL rating

The CD4078BM96 meets all substitution criteria as a direct equivalent within the 4000B series, with identical functional specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The CD4078BM96 is the direct substitute for the discontinued CD4078BM. Both parts are manufactured by Texas Instruments within the 4000B logic series and share identical electrical specifications, pin configuration, and package dimensions.

Selection of the CD4078BM96 requires no design modifications, as all functional and mechanical parameters remain equivalent to the original CD4078BM specification.

Frequently Asked Questions (FAQ)

Q: Can the CD4078BM96 be used as a direct replacement for the CD4078BM?

A: Yes. The CD4078BM96 is electrically and mechanically equivalent to the CD4078BM. Both devices feature identical logic configuration (8-input NOR/OR gate), output characteristics (6.8mA), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and 14-SOIC package dimensions. No circuit modifications are required.

Q: What is the difference between the CD4078BM and CD4078BM96?

A: The primary difference is product status and packaging format. The CD4078BM is discontinued and was supplied in tube packaging. The CD4078BM96 is an active product supplied in cut tape and Digi-Reel formats, providing improved availability and supply chain continuity.

Q: Are there any pin configuration differences between these parts?

A: No. Both the CD4078BM and CD4078BM96 use the 14-SOIC package with identical pin assignments. PCB layouts and footprints are fully compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CD4078BM and CD4078BM96 are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. REACH status is unaffected for both parts.

Q: What supply voltage range is supported by the CD4078BM96?

A: The CD4078BM96 operates across a supply voltage range of 3V to 18V, identical to the original CD4078BM specification.
