Substitute Part Grouping Explanation

Substitute parts for the CD4041UBM are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criterion is the CD4041 base product number, which ensures identical functional characteristics. Acceptable substitutes must maintain the following parameters without deviation:

• Logic Type: Buffer, Line Driver
• Number of Elements: 4
• Number of Bits per Element: 1
• Output Type: Complementary
• Current - Output High, Low: 38mA, 38mA
• Voltage - Supply: 3V ~ 18V
• Operating Temperature: -55°C ~ 125°C (TA)
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variations in packaging format (Tube versus Cut Tape & Digi-Reel) and product status do not affect functional equivalence and are permitted substitution variables.

Parameter Comparison

Engineering Selection Recommendations

The CD4041UBM96 is the direct functional equivalent of the CD4041UBM. Both parts share identical electrical specifications, thermal characteristics, and package geometry. The primary distinction is product status: the CD4041UBM is Last Time Buy, while the CD4041UBM96 maintains Active status with higher inventory availability (3220 Pcs versus 1196 Pcs). Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. Selection between these parts should be based on procurement requirements and inventory availability rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are CD4041UBM and CD4041UBM96 electrically interchangeable?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, including output current (38mA high and low), supply voltage range (3V to 18V), and operating temperature range (-55°C to 125°C). They share the same base product number (CD4041) and functional configuration.

Q: What is the difference between Tube and Cut Tape & Digi-Reel packaging?

A: Tube and Cut Tape & Digi-Reel are packaging formats that affect handling and automated assembly processes. The physical component and electrical performance remain identical. Tube packaging is typically used for manual handling, while Cut Tape & Digi-Reel format is optimized for automated pick-and-place equipment.

Q: Why is CD4041UBM marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued this part number and will no longer produce it after existing inventory is depleted. The CD4041UBM96 is the active equivalent and should be considered for new designs and future procurement.

Q: Can I use CD4041UBM96 as a direct replacement in existing designs?

A: Yes. The CD4041UBM96 is a direct functional replacement. No circuit modifications or design changes are required. The 14-SOIC package dimensions and pinout are identical, allowing for direct PCB compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both CD4041UBM and CD4041UBM96 are ROHS3 compliant and carry MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.
