Key Parameters

Substitute Part Grouping Explanation

Substitution of the A6B595KLW-T is determined by the following critical parameters:

• Package compatibility: 20-SOIC form factor (0.295", 7.50mm Width)
• Output channel count: 8 channels
• Supply voltage range: 4.5V ~ 5.5V
• Output configuration: Low-side switching with N-channel topology
• Interface type: Serial input with strobe control
• Mounting type: Surface mount

The substitute parts identified (TPIC6B595DW and TPIC6B595DWR) are Texas Instruments components that share the same base product number (TPIC6B595) and maintain functional equivalence through identical package geometry, channel count, supply voltage specifications, and serial-to-parallel shift register architecture with open-drain output configuration.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the A6B595KLW-T, the TPIC6B595DWR is the preferred substitute due to its active product status with Texas Instruments, ensuring ongoing availability and supply chain continuity. Both TPIC6B595DW and TPIC6B595DWR maintain identical electrical specifications and package geometry, with the primary distinction being product lifecycle status and packaging format (Tube versus Cut Tape & Digi-Reel).

The TPIC6B595DWR offers an extended operating temperature range (-40°C ~ 125°C) compared to the original A6B595KLW-T (-40°C ~ 85°C), providing additional thermal margin for demanding applications. All substitute components maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can TPIC6B595DW and TPIC6B595DWR be used interchangeably with A6B595KLW-T?

A: Both Texas Instruments components are functionally equivalent substitutes. They share identical 20-SOIC package geometry, 8-channel output configuration, 4.5V ~ 5.5V supply voltage range, and serial-to-parallel shift register architecture. Pin-to-pin compatibility is maintained across all three parts.

Q: What is the difference between TPIC6B595DW and TPIC6B595DWR?

A: The primary differences are packaging format and product status. TPIC6B595DW is supplied in Tube packaging with obsolete status, while TPIC6B595DWR is supplied in Cut Tape & Digi-Reel format with active product status. Electrical specifications and package dimensions are identical.

Q: Does the extended operating temperature range of the TPIC6B595DWR affect compatibility?

A: No. The extended range (-40°C ~ 125°C versus -40°C ~ 85°C) represents an enhancement that does not impact compatibility. Applications operating within the original temperature specification remain fully compatible.

Q: Are all substitute parts RoHS compliant?

A: Yes. The A6B595KLW-T and both TPIC6B595 variants are ROHS3 compliant with MSL 1 rating, meeting standard environmental and manufacturing requirements.

Q: Which substitute should be selected for new designs?

A: TPIC6B595DWR is recommended for new designs due to its active product status, ensuring long-term availability and supply chain support from Texas Instruments.
