CD4515BM Equivalent & Substitute Parts

Part Overview

The CD4515BM is a Decoder/Demultiplexer logic integrated circuit manufactured by Texas Instruments, configured as a 1 x 4:16 decoder in a 24-SOIC surface mount package. This part operates across a dual supply voltage range of 3V to 18V and supports operating temperatures from -55°C to 125°C. The CD4515BM is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD4515BM are classified based on strict adherence to the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: 1 x 4:16 decoder/demultiplexer
• Package type: 24-SOIC surface mount
• Voltage supply range: 3V ~ 18V minimum
• Operating temperature range: -55°C ~ 125°C minimum
• Output current capability: 6.8mA or greater for both high and low states
• RoHS3 compliance

Substitute Categories:

Direct Equivalent (Packaging Variant): CD4515BM96 — Identical electrical specifications and base product number as the main part, differing only in packaging format (Tape & Reel versus Tube).

Manufacturer Recommended Substitute: MC14515BDWR2G — onsemi equivalent with matching circuit configuration, package, and voltage supply range. Voltage supply source is single supply rather than dual supply. Output current specifications differ: 4.6mA high, 8.8mA low. Moisture sensitivity level is MSL 3 (168 Hours) versus MSL 1.

Parametric Equivalent: CD4514BM — Texas Instruments alternative decoder/demultiplexer with identical electrical parameters to the main part. Differs in base product number (CD4514 versus CD4515) but maintains the same circuit configuration, package, voltage range, and output current specifications.

Parameter Comparison

Engineering Selection Recommendations

CD4515BM96: Select this part as the primary substitute when direct equivalence is required. It maintains identical electrical specifications, RoHS3 compliance, and MSL 1 rating. The only difference is packaging format (Tape & Reel), which does not affect electrical performance. This part is currently active in inventory.

MC14515BDWR2G: Select this onsemi part when supply constraints require a cross-manufacturer solution. It meets all critical substitution criteria including circuit configuration, package type, and voltage supply range. Note that the voltage supply source is single supply rather than dual supply, and output current specifications differ (4.6mA high versus 6.8mA high). The MSL 3 rating requires controlled storage conditions (168 hours maximum at 85°C/85% RH). This part is currently active in inventory.

CD4514BM: Select this part when an alternative Texas Instruments decoder/demultiplexer is required. It provides identical electrical performance to the main part with matching output current, voltage range, and operating temperature specifications. Both the main part and this substitute are discontinued at DiGi Electronics, so availability should be verified before selection.

Frequently Asked Questions (FAQ)

Q: Can CD4515BM96 be used as a direct replacement for CD4515BM?

A: Yes. CD4515BM96 is electrically identical to CD4515BM. The only difference is packaging format: CD4515BM is supplied in Tube packaging, while CD4515BM96 is supplied in Tape & Reel format. Both are 24-SOIC surface mount packages with identical pin configurations and electrical specifications.

Q: What is the key difference between CD4515BM and MC14515BDWR2G?

A: Both parts are 1 x 4:16 decoders in 24-SOIC packages with 3V to 18V supply voltage range. The primary differences are: (1) MC14515BDWR2G uses single supply voltage source versus dual supply for CD4515BM; (2) output current specifications differ—MC14515BDWR2G provides 4.6mA high and 8.8mA low versus 6.8mA for both on CD4515BM; (3) MC14515BDWR2G has MSL 3 rating requiring controlled storage versus MSL 1 unlimited for CD4515BM.

Q: Is CD4514BM a suitable substitute for CD4515BM?

A: CD4514BM is a parametric equivalent with identical electrical specifications including output current (6.8mA, 6.8mA), voltage supply range (3V ~ 18V), and operating temperature (-55°C ~ 125°C). Both are Texas Instruments 4000B series decoders in 24-SOIC packages. The base product number differs (CD4514 versus CD4515), but electrical performance is equivalent. Both parts are currently discontinued at DiGi Electronics.

Q: Which substitute part has the best current availability?

A: CD4515BM96 and MC14515BDWR2G are both currently active with inventory available. CD4515BM96 has 7547 pieces in stock, while MC14515BDWR2G has 1725 pieces in stock. CD4514BM is discontinued at DiGi Electronics with 2360 pieces available from existing inventory.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CD4515BM96, MC14515BDWR2G, and CD4514BM are all ROHS3 compliant. All parts are also REACH unaffected and classified under ECCN EAR99.

Q: What is the significance of the MSL rating difference between CD4515BM and MC14515BDWR2G?

A: CD4515BM has MSL 1 (Unlimited), meaning it can be stored indefinitely without moisture absorption concerns. MC14515BDWR2G has MSL 3 (168 Hours), requiring that the part be used within 168 hours of exposure to 85°C and 85% relative humidity conditions. This affects handling, storage, and assembly procedures for MC14515BDWR2G.
