Engineering Selection Recommendations
The CD74HC154M96E4 is discontinued at DiGi Electronics. Direct substitution is available through three active alternatives: CD74HC154M96, CD74HC4514M96, and CD74HC4515M96. All three parts maintain identical electrical specifications and 24-SOIC packaging.
For new designs and ongoing procurement, CD74HC154M96 is the primary substitute, offering the highest inventory availability (25990 pcs) and direct part number continuity. Both CD74HC4514M96 and CD74HC4515M96 provide equivalent parametric performance with lower inventory levels.
All substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Moisture sensitivity level remains at MSL 1 (Unlimited) across all alternatives, eliminating special handling requirements.
Frequently Asked Questions (FAQ)
Q: Can CD74HC154M96 directly replace CD74HC154M96E4?
A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications. The primary difference is product status: CD74HC154M96 is active with higher inventory availability, while CD74HC154M96E4 is discontinued.
Q: Are CD74HC4514M96 and CD74HC4515M96 compatible substitutes?
A: Yes. Both parts match all critical parameters: 1 x 4:16 decoder/demultiplexer configuration, 5.2mA output current, 2V ~ 6V supply voltage, 24-SOIC package, and -55°C ~ 125°C operating temperature range.
Q: Does packaging differ between substitute parts?
A: No. All parts use 24-SOIC (0.295", 7.50mm Width) surface mount packaging. PCB layout and footprint compatibility is maintained across all substitutes.
Q: Are there compliance or regulatory differences?
A: No. All parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.
Q: Which substitute offers the best availability?
A: CD74HC154M96 provides the highest inventory level at 25990 pcs, followed by CD74HC4514M96 (2202 pcs) and CD74HC4515M96 (2100 pcs).
