Substitute Part Grouping Explanation

Substitute parts for the SN74HC595DBRG4 are determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: Tri-State
• Function: Serial to Parallel, Serial
• Voltage - Supply: 2V ~ 6V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 16-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Base Product Number: 74HC595

All substitute parts maintain identical electrical performance and mechanical compatibility. Packaging format (Tape & Reel or Cut Tape) represents the only variation and does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both SN74HC595ADBR and SN74HC595DBR are direct functional equivalents to the SN74HC595DBRG4. Selection between these substitutes should be based on:

Product Status: Both substitute parts maintain active product status with Texas Instruments, ensuring long-term availability and supply chain reliability compared to the discontinued SN74HC595DBRG4.

Compliance & Certifications: All three parts are ROHS3 compliant and REACH unaffected, maintaining identical environmental and regulatory compliance profiles.

Packaging Availability: SN74HC595DBR offers the widest packaging flexibility with availability in both Cut Tape (CT) and Digi-Reel® formats, providing maximum procurement options. SN74HC595ADBR is available in Tape & Reel (TR) format.

Inventory Considerations: SN74HC595DBR maintains the highest inventory levels (17,400 pcs), followed by SN74HC595ADBR (3,400 pcs), supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Are SN74HC595ADBR and SN74HC595DBR fully compatible with SN74HC595DBRG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, pin configurations, and 16-SSOP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between the packaging formats offered?

A: Packaging format refers to the supply method: Tape & Reel (TR) provides components on continuous tape for automated assembly, Cut Tape (CT) provides tape segments for manual or small-batch assembly, and Digi-Reel® is a proprietary format. All formats contain identical components with no functional differences.

Q: Why is the SN74HC595DBRG4 discontinued?

A: Product discontinuation typically reflects manufacturer supply chain optimization. Active equivalent parts (SN74HC595ADBR and SN74HC595DBR) provide identical functionality with improved availability.

Q: Can I use these substitutes in existing designs without PCB modification?

A: Yes. The 16-SSOP package dimensions (0.209", 5.30mm width) and pin configuration are identical across all three parts, enabling direct PCB compatibility.

Q: What compliance certifications apply to these substitute parts?

A: All parts are ROHS3 compliant and REACH unaffected, maintaining identical environmental compliance status.
