CD4041UBPW Equivalent & Substitute Parts

Part Overview

The CD4041UBPW is a Buffer, Line Driver logic integrated circuit manufactured by Texas Instruments, designed for 4-element complementary output applications. This device operates across a wide supply voltage range of 3V to 18V and is housed in a 14-TSSOP surface mount package. The CD4041UBPW is classified as Last Time Buy, indicating that the original part is no longer in active production. Identifying equivalent substitute parts is necessary to ensure continued availability and support for designs currently utilizing this component or for new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4041UBPW is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Line Driver with 4 elements
• Output Configuration: Complementary output
• Output Current Capability: 38mA high and low
• Supply Voltage Range: 3V to 18V
• Operating Temperature Range: -55°C to 125°C
• Package Type: 14-TSSOP surface mount
• Electrical and mechanical pin compatibility

The CD4041UBPWR qualifies as a direct substitute because it maintains identical electrical specifications, pin configuration, and package dimensions. The difference between these parts lies in packaging format and product status, not in functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CD4041UBPWR is the direct equivalent substitute for the CD4041UBPW. Both parts are manufactured by Texas Instruments and share identical electrical specifications, pin configurations, and package dimensions. The primary distinction is product status: the CD4041UBPW is Last Time Buy, while the CD4041UBPWR maintains Active status with higher inventory availability.

Selection of the CD4041UBPWR is supported by:

• Identical functional and electrical characteristics across all specified parameters
• ROHS3 compliance maintained in both variants
• Unlimited moisture sensitivity level (MSL 1) for both parts
• Continued manufacturing and availability of the CD4041UBPWR
• Pin-for-pin compatibility with no design modifications required

Frequently Asked Questions (FAQ)

Q: Can the CD4041UBPWR be used as a direct replacement for the CD4041UBPW in existing designs?

A: Yes. The CD4041UBPWR is electrically and mechanically identical to the CD4041UBPW. No circuit modifications or PCB redesign is required. Both parts are housed in the same 14-TSSOP package with identical pin assignments and electrical performance.

Q: What is the difference between the CD4041UBPW and CD4041UBPWR?

A: The primary difference is packaging format and product status. The CD4041UBPW is supplied in Tube packaging and is Last Time Buy. The CD4041UBPWR is supplied in Cut Tape (CT) and Digi-Reel® formats and maintains Active product status with higher inventory levels.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the CD4041UBPW and CD4041UBPWR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: What are the critical parameters that define substitution eligibility for the CD4041 series?

A: Substitution is determined by matching: logic type (Buffer, Line Driver), element count (4), output type (Complementary), output current (38mA high and low), supply voltage range (3V to 18V), operating temperature range (-55°C to 125°C), and package type (14-TSSOP surface mount).

Q: Is the 14-TSSOP package footprint identical between both parts?

A: Yes. Both parts use the 14-TSSOP package with dimensions of 0.173" × 4.40mm width. PCB footprints and land patterns are identical.
