Substitute Part Grouping Explanation

Substitute parts for the CD4514BM are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

• Identical circuit configuration: 1 x 4:16 Decoder/Demultiplexer
• Matching package type: 24-SOIC surface mount
• Compatible voltage supply range: 3V ~ 18V
• Matching operating temperature range: -55°C ~ 125°C
• Equivalent output current specifications
• Compliance with RoHS3 and REACH requirements

The substitute parts are grouped into two categories: direct manufacturer equivalents from Texas Instruments with identical electrical specifications, and parametric equivalents from alternative manufacturers that meet the functional and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

CD4514BM96 is the primary direct substitute for CD4514BM. Both parts are manufactured by Texas Instruments with identical electrical specifications, circuit configuration, and package type. CD4514BM96 maintains active product status, ensuring continued availability and supply chain reliability. The only difference is packaging format: CD4514BM is supplied in Tube packaging, while CD4514BM96 is supplied in Cut Tape and Digi-Reel format. This substitution requires no design modifications.

CD4515BM is a parametric equivalent from Texas Instruments with identical electrical and mechanical specifications to CD4514BM. The base product number differs (CD4515 versus CD4514), but all functional parameters remain equivalent. CD4515BM is also discontinued at DiGi Electronics, limiting its practical availability for new procurement.

MC14514BDWR2G is a parametric equivalent manufactured by onsemi that meets the core functional requirements of 1 x 4:16 decoder/demultiplexer operation in a 24-SOIC package. This part maintains active product status and ROHS3 compliance. However, the MC14514BDWR2G differs in voltage supply source classification (single supply versus dual supply) and output current specifications (4.6mA high, 8.8mA low versus 6.8mA symmetrical). The MSL rating is also higher at 3 (168 Hours) compared to 1 (Unlimited). These differences require circuit-level evaluation for compatibility in specific applications.

Frequently Asked Questions (FAQ)

Q: Can CD4514BM96 be used as a direct replacement for CD4514BM?

A: Yes. CD4514BM96 is a direct substitute with identical electrical specifications, circuit configuration, and package type. The difference is packaging format only. No design modifications are required.

Q: What is the difference between CD4514BM and CD4515BM?

A: Both parts are manufactured by Texas Instruments with identical electrical and mechanical specifications. The primary difference is the base product number designation (CD4514 versus CD4515). All functional parameters, including circuit configuration, voltage supply range, output current, and operating temperature, are equivalent.

Q: Can MC14514BDWR2G replace CD4514BM in all applications?

A: MC14514BDWR2G meets the core functional requirements as a 1 x 4:16 decoder/demultiplexer in a 24-SOIC package. However, differences exist in voltage supply source classification and output current specifications. Circuit-level evaluation is necessary to confirm compatibility with specific application requirements.

Q: Why is CD4514BM discontinued?

A: CD4514BM is listed as discontinued at DiGi Electronics. CD4514BM96 and MC14514BDWR2G are active alternatives with current availability.

Q: What is the significance of the MSL rating difference between CD4514BM and MC14514BDWR2G?

A: CD4514BM has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. MC14514BDWR2G has an MSL rating of 3 (168 Hours), requiring controlled storage and handling conditions. This affects storage, shipping, and assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CD4514BM, CD4514BM96, CD4515BM, and MC14514BDWR2G are all ROHS3 compliant and REACH unaffected.
