Substitute Part Grouping Explanation

Substitution of the CD4048BPWR with the CD4048BPW is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is based on the following matching criteria:

• Logic Type: Multifunction Expandable (identical)
• Number of Circuits: 1 (identical)
• Number of Inputs: 8 (identical)
• Output Type: Single-Ended (identical)
• Current - Output High, Low: 6.8mA, 6.8mA (identical)
• Voltage - Supply: 3V ~ 18V (identical)
• Operating Temperature: -55°C ~ 125°C (identical)
• Package / Case: 16-TSSOP (0.173", 4.40mm Width) (identical)
• Mounting Type: Surface Mount (identical)
• Series: 4000B (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The CD4048BPW differs only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard), with no functional or electrical deviation.

Parameter Comparison

Engineering Selection Recommendations

The CD4048BPW is the direct active equivalent for the obsolete CD4048BPWR. Selection of the CD4048BPW is appropriate for all applications currently using or requiring the CD4048BPWR, as it maintains identical electrical specifications, thermal operating range, supply voltage range, and output current characteristics. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The CD4048BPW's active product status provides assured long-term availability and manufacturing support, eliminating supply chain risk associated with obsolete components.

Frequently Asked Questions (FAQ)

Q: Can the CD4048BPW directly replace the CD4048BPWR in existing designs?

A: Yes. The CD4048BPW is electrically and mechanically identical to the CD4048BPWR across all specified parameters. No design modifications are required for substitution.

Q: What is the difference between CD4048BPWR and CD4048BPW?

A: The primary difference is product status: CD4048BPWR is obsolete while CD4048BPW is active. The packaging format differs (standard vs. Tube), but electrical and functional specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Does the 16-TSSOP package remain the same for both parts?

A: Yes. Both parts use the 16-TSSOP package with 0.173" width (4.40mm), maintaining identical PCB footprint and mounting requirements.

Q: What is the supply voltage range for these parts?

A: Both the CD4048BPWR and CD4048BPW operate across a supply voltage range of 3V to 18V.
