Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC597DB,112 is determined by strict alignment across the following critical parameters:

• Logic Type: Shift Register
• Number of Elements: 1
• Number of Bits per Element: 8
• Function: Parallel to Serial
• Output Type: Push-Pull
• Voltage - Supply: 2V ~ 6V
• Operating Temperature: -40°C ~ 125°C
• Base Product Number: 74HC597
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The 74HC597PW,118 meets all substitution criteria. Differences in package configuration (16-SSOP versus 16-TSSOP) and product status (Obsolete versus Active) do not affect functional equivalence when PCB layout and mechanical constraints permit package variation.

Parameter Comparison

Engineering Selection Recommendations

The 74HC597PW,118 is the qualified substitute for the 74HC597DB,112 based on the following engineering criteria:

Functional Equivalence: Both components share identical logic specifications, electrical performance parameters, and operational characteristics across all critical functional domains.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and deployment standards.

Supply Chain Status: The 74HC597PW,118 carries Active product status with substantial inventory availability (120,300 pcs), whereas the 74HC597DB,112 is Obsolete. Selection of the active substitute ensures long-term supply continuity and reduces procurement risk.

Package Consideration: The substitute employs a 16-TSSOP package (0.173" width) compared to the original 16-SSOP package (0.209" width). PCB layout modification is required to accommodate the narrower package footprint. Both packages maintain identical pin count and electrical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can the 74HC597PW,118 directly replace the 74HC597DB,112 without circuit modification?

A: Electrical and functional replacement is direct. PCB layout modification is required due to package footprint differences (16-SSOP versus 16-TSSOP). Pin assignments and electrical characteristics remain identical.

Q: What is the significance of the Obsolete status for the 74HC597DB,112?

A: Obsolete status indicates the manufacturer has discontinued production. The 74HC597PW,118 substitute maintains Active status with ongoing manufacturing support and availability.

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

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: How do the package dimensions affect component selection?

A: The 74HC597PW,118 uses a narrower 16-TSSOP package (4.40mm width) versus the 16-SSOP package (5.30mm width) of the original part. Design layout must accommodate this dimensional change. Pin pitch and electrical interface remain compatible.
