Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPIC6C596PWRG4 are classified based on strict parameter alignment. The primary substitution criteria are:

Core Electrical Parameters:

• Logic Type: Shift Register
• Number of Bits per Element: 8
• Output Type: Open Drain
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C
• Function: Serial to Parallel, Serial

Mechanical Parameters:

• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

Parts meeting all core electrical, mechanical, and compliance parameters are classified as parametric equivalents or manufacturer-recommended substitutes. Deviations in secondary parameters (such as MSL rating, product status, or manufacturer) are noted but do not disqualify substitution eligibility when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Parametric Equivalents (Recommended for Immediate Replacement):

TPIC6C596PWR and TPIC6C595PWR are direct parametric equivalents manufactured by Texas Instruments. Both maintain identical core electrical specifications, package geometry, and RoHS compliance. TPIC6C596PWR carries Last Time Buy status, while TPIC6C595PWR is Active, making it the preferred choice for new designs requiring long-term availability.

Tier 2 - Cross-Manufacturer Equivalents (Alternative Sources):

STPIC6C595TTR and STPIC6D595TTR from STMicroelectronics meet all core electrical and mechanical parameters. Both are Active products with high inventory availability. MSL rating differs (3 vs. 1), requiring consideration for moisture-sensitive storage environments. NPIC6C596PW-Q100,1 from Nexperia USA Inc. provides automotive-grade qualification (AEC-Q100) but is classified as Obsolete.

Tier 3 - Functional Alternative (Application-Dependent):

TLC6C598QPWRQ1 from Texas Instruments operates as a power switch with integrated shift register functionality, extending supply voltage range to 3V minimum and supporting 50mA output current per channel. This device is suitable for LED driver and power management applications but introduces functional differences requiring circuit-level evaluation.

Frequently Asked Questions (FAQ)

Q: Can TPIC6C595PWR directly replace TPIC6C596PWRG4 without circuit modification?

A: Yes. Both devices share identical core electrical parameters, output type, supply voltage range, operating temperature, and 16-TSSOP package. No circuit modification is required for direct substitution.

Q: What is the difference between TPIC6C596PWR and TPIC6C595PWR?

A: Both are parametric equivalents with identical electrical specifications and package. The primary difference is product status: TPIC6C596PWR is Last Time Buy, while TPIC6C595PWR is Active. For new designs, TPIC6C595PWR is preferred due to ongoing availability.

Q: Are STMicroelectronics parts (STPIC6C595TTR, STPIC6D595TTR) suitable replacements?

A: Yes, both STMicroelectronics parts meet all core electrical and mechanical parameters. The MSL rating is 3 (168 Hours) versus 1 (Unlimited) for the original part, requiring appropriate moisture control during storage and handling.

Q: What makes TLC6C598QPWRQ1 different from other substitutes?

A: TLC6C598QPWRQ1 is classified as a power switch rather than a logic shift register. It provides integrated LED driver functionality with 50mA per-channel output capability and extended supply voltage range (3V minimum). This device is suitable for LED and power management applications but requires circuit-level evaluation for compatibility.

Q: Does NPIC6C596PW-Q100,1 offer advantages over other substitutes?

A: NPIC6C596PW-Q100,1 includes automotive-grade qualification (AEC-Q100), making it suitable for automotive applications. However, it is classified as Obsolete. For automotive requirements, TLC6C598QPWRQ1 (also AEC-Q100 qualified) is the active alternative.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original TPIC6C596PWRG4 specification.

Q: What packaging considerations apply to these substitutes?

A: All substitute parts use the 16-TSSOP package with 0.173" width (4.40mm), ensuring mechanical compatibility with existing PCB layouts and assembly processes.
