Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC7541DB,112 is determined by strict equivalence across the following critical parameters:

• Logic type and functional architecture (Buffer, Non-Inverting)
• Element and bit configuration (1 Element, 8 Bits per Element)
• Input and output characteristics (Schmitt Trigger input, 3-State output)
• Electrical performance (Output current: 7.8mA/7.8mA; Supply voltage: 2V ~ 6V)
• Operating temperature range (-40°C ~ 125°C)
• Base product number (74HC7541)
• Compliance certifications (ROHS3, REACH Unaffected)

The identified substitute part maintains functional and electrical equivalence while differing in packaging format and product status. Package compatibility must be evaluated based on PCB design requirements and assembly capabilities.

Parameter Comparison

Engineering Selection Recommendations

The 74HC7541PW,118 is the direct functional equivalent to the 74HC7541DB,112. Both parts share identical logic architecture, electrical specifications, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The primary distinction is product status: the 74HC7541PW,118 maintains Active status with significantly higher inventory availability (17,562 pcs vs. 918 pcs), ensuring long-term supply chain viability. This substitute is recommended for new designs and ongoing production requirements.

Package format differs between the two parts: the main part uses 20-SSOP packaging (5.30mm width), while the substitute uses 20-TSSOP packaging (4.40mm width). PCB layout and assembly equipment compatibility must be evaluated before implementation. Both are surface-mount packages with identical pin counts and electrical interfaces.

Frequently Asked Questions (FAQ)

Q: Are the 74HC7541DB,112 and 74HC7541PW,118 electrically interchangeable?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, including supply voltage range (2V ~ 6V), output current (7.8mA/7.8mA), operating temperature range (-40°C ~ 125°C), and functional architecture (non-inverting buffer with 3-state output).

Q: What is the difference between 20-SSOP and 20-TSSOP packaging?

A: Both are 20-pin surface-mount packages with identical pin configurations and electrical interfaces. The primary difference is physical dimensions: 20-SSOP has a 5.30mm width, while 20-TSSOP has a 4.40mm width. PCB footprint design and assembly equipment must accommodate the selected package format.

Q: Why is the 74HC7541DB,112 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The 74HC7541PW,118 substitute maintains Active status and is the recommended choice for new designs and ongoing production support.

Q: Can I use the 74HC7541PW,118 in existing designs using the 74HC7541DB,112?

A: Electrical substitution is valid. However, PCB layout modifications may be required due to package format differences (SSOP vs. TSSOP). Assembly equipment compatibility must be confirmed before implementation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 74HC7541DB,112 and 74HC7541PW,118 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
