Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4515BME4 is determined by the following critical parameters: circuit configuration (1 x 4:16), package type (24-SOIC), mounting method (Surface Mount), voltage supply range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and output current specifications (6.8mA high/low). Parts meeting these electrical and mechanical criteria are classified as direct or parametric equivalents.

The substitute parts are grouped as follows:

Direct Manufacturer Equivalents: CD4515BM96 and CD4515BM share identical electrical specifications with the main part, differing only in packaging format (Tape & Reel and Tube respectively).

Manufacturer Recommended Equivalent: MC14515BDWR2G (onsemi) maintains the same circuit configuration, package, and voltage supply range. This part operates under single supply configuration with different output current specifications (4.6mA high, 8.8mA low) and higher moisture sensitivity (MSL 3).

Parametric Equivalent: CD4514BM matches all critical electrical and mechanical parameters of the CD4515BME4, including dual supply voltage, output currents, and temperature range, with identical package specifications.

Parameter Comparison

Engineering Selection Recommendations

CD4515BM96 is the primary substitute for the CD4515BME4. This part maintains complete electrical and mechanical compatibility with identical output current specifications and dual supply voltage configuration. CD4515BM96 is currently active in production with unlimited moisture sensitivity, making it suitable for standard storage and handling conditions.

CD4515BM provides equivalent functionality with identical electrical parameters and is available in Tube packaging. This part is discontinued at DiGi Electronics but remains a valid parametric match for applications requiring dual supply operation and 6.8mA output currents.

MC14515BDWR2G (onsemi) is a cross-manufacturer equivalent that maintains the 1 x 4:16 circuit configuration and 24-SOIC package. This part operates under single supply configuration with asymmetrical output currents (4.6mA high, 8.8mA low) and requires MSL 3 moisture sensitivity handling (168-hour limit). Selection of this part requires verification that single supply operation and modified output current specifications are compatible with the application circuit.

CD4514BM is a parametric equivalent offering identical electrical specifications to the CD4515BME4, including dual supply voltage and output current ratings. This part is discontinued at DiGi Electronics but provides full compatibility for designs requiring the same functional and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can CD4515BM96 directly replace CD4515BME4 in production?

A: Yes. CD4515BM96 is electrically and mechanically identical to CD4515BME4, with the same dual supply voltage range (3V ~ 18V), output current specifications (6.8mA high/low), and 24-SOIC package. The primary difference is packaging format (Tape & Reel versus individual packaging) and active product status.

Q: What is the key difference between CD4515BME4 and MC14515BDWR2G?

A: MC14515BDWR2G differs in three aspects: manufacturer (onsemi versus Texas Instruments), supply configuration (single supply versus dual supply), and output current specifications (4.6mA high, 8.8mA low versus 6.8mA symmetric). Additionally, MC14515BDWR2G requires MSL 3 moisture sensitivity handling with a 168-hour limit, compared to unlimited MSL 1 for the CD4515BME4.

Q: Are all substitute parts available in the same 24-SOIC package?

A: Yes. All substitute parts listed (CD4515BM96, CD4515BM, MC14515BDWR2G, and CD4514BM) are housed in 24-SOIC (0.295", 7.50mm Width) surface mount packages, ensuring mechanical compatibility with existing PCB designs.

Q: What does "Discontinued at DiGi Electronics" mean for part selection?

A: This status indicates the part is no longer actively stocked by DiGi Electronics but may remain available through other distributors or inventory channels. For new designs or ongoing production, active parts such as CD4515BM96 or MC14515BDWR2G are recommended to ensure supply chain continuity.

Q: Can CD4514BM be used as a substitute for CD4515BME4?

A: Yes. CD4514BM is a parametric equivalent with identical electrical specifications, including dual supply voltage (3V ~ 18V), output currents (6.8mA high/low), and operating temperature range (-55°C ~ 125°C). Both parts are housed in 24-SOIC packages and are ROHS3 compliant.

Q: What is the significance of MSL rating differences between substitute parts?

A: Moisture Sensitivity Level (MSL) determines storage and handling requirements. CD4515BME4, CD4515BM96, and CD4514BM have MSL 1 (unlimited storage), while MC14515BDWR2G has MSL 3 (168-hour limit after bag opening). MSL 3 parts require controlled humidity environments and faster assembly processing to prevent moisture absorption damage.
