TPIC6C596PWR Equivalent & Substitute Parts

Part Overview

The TPIC6C596PWR is an 8-bit shift register IC manufactured by Texas Instruments in a 16-TSSOP surface mount package. This device functions as a serial-to-parallel converter with open drain outputs, operating across a 4.5V to 5.5V supply voltage range and -40°C to 125°C temperature range. The part is currently in Last Time Buy status, indicating production discontinuation. Identifying equivalent and substitute components is necessary to ensure design continuity and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPIC6C596PWR is determined by the following critical 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
• Package / Case: 16-TSSOP
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical and mechanical specifications across all critical parameters. These parts are direct functional replacements with no design modifications required.

Manufacturer-Recommended Substitute (TLC6C598QPWRQ1) operates within the supply voltage range but differs in functional topology (LED driver with power switch capability) and output current rating (50mA per channel). This part is suitable only for applications where the enhanced output capability and dimming functionality do not conflict with circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Pin-Compatible Replacement):

TPIC6C595PWR and STPIC6C595TTR are parametric equivalents with identical electrical specifications and 16-TSSOP packaging. TPIC6C595PWR maintains Active product status from Texas Instruments. STPIC6C595TTR is an Active alternative from STMicroelectronics with higher inventory availability (125,300 units). Both are ROHS3 compliant and suitable for direct substitution in existing designs.

STPIC6D595TTR is functionally equivalent to STPIC6C595TTR with identical electrical parameters and Active status. Selection between STPIC6C595TTR and STPIC6D595TTR depends on specific application requirements and manufacturer part number compatibility.

Automotive-Grade Alternatives:

NPIC6C596PW-Q100,1 (Nexperia) carries AEC-Q100 automotive qualification and is suitable for applications requiring automotive-grade components. This part is currently Obsolete but maintains parametric equivalence with the main part.

Manufacturer-Recommended Substitute (Functional Variant):

TLC6C598QPWRQ1 is designated as the manufacturer-recommended substitute. This part operates as an LED driver with integrated power switch topology and 50mA output current per channel. It maintains the 16-TSSOP package and -40°C to 125°C operating range but extends the minimum supply voltage to 3V and includes AEC-Q100 automotive qualification. This part is suitable only for applications where the power switch functionality and enhanced output current capability align with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can TPIC6C595PWR be used as a direct replacement for TPIC6C596PWR?

A: Yes. TPIC6C595PWR is a parametric equivalent with identical electrical specifications, supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), 8-bit shift register function, open drain output type, and 16-TSSOP package. The part is currently in Active status and maintains ROHS3 compliance.

Q: What is the difference between STPIC6C595TTR and STPIC6D595TTR?

A: Both parts are parametric equivalents from STMicroelectronics with identical electrical specifications, supply voltage, operating temperature, package type, and output characteristics. Selection between these parts depends on application-specific requirements and manufacturer part number compatibility.

Q: Is TLC6C598QPWRQ1 a direct replacement for TPIC6C596PWR?

A: TLC6C598QPWRQ1 is a functional variant, not a direct replacement. While both parts operate within overlapping supply voltage ranges and share the 16-TSSOP package, TLC6C598QPWRQ1 functions as an LED driver with power switch topology and 50mA output current per channel, whereas TPIC6C596PWR is a standard shift register with open drain outputs. This part is suitable only for applications where the enhanced output capability and dimming functionality do not conflict with circuit design.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: TPIC6C596PWR, TPIC6C595PWR, TPIC6C596PWRG4, and NPIC6C596PW-Q100,1 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. STPIC6C595TTR, STPIC6D595TTR, and TLC6C598QPWRQ1 carry MSL 3 (168 Hours), requiring controlled moisture exposure during storage and implementation of appropriate handling procedures.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, consistent with the main part TPIC6C596PWR.

Q: Which substitute parts carry automotive qualification?

A: NPIC6C596PW-Q100,1 and TLC6C598QPWRQ1 carry AEC-Q100 automotive qualification. These parts are suitable for applications requiring automotive-grade component certification.
