Substitute Part Grouping Explanation

Substitution eligibility for the TPIC6596DWR is determined by strict parametric equivalence across the following critical criteria:

Logic configuration: Shift register with 1 element and 8 bits per element Output architecture: Open drain topology Electrical specifications: 4.5V to 5.5V supply voltage range and -40°C to 125°C operating temperature Physical form factor: 20-SOIC surface mount package with identical 0.295" (7.50mm) width Functional capability: Serial-to-parallel and serial output functions

The identified substitute parts TPIC6595DWR and TPIC6B595DWR meet all parametric requirements for direct substitution. Both alternatives maintain identical electrical performance, package geometry, and functional characteristics as the original TPIC6596DWR.

Parameter Comparison

Engineering Selection Recommendations

Both TPIC6595DWR and TPIC6B595DWR are active products with current manufacturing status and full availability. These alternatives provide superior compliance posture compared to the discontinued TPIC6596DWR, as both substitute parts carry ROHS3 certification. The original TPIC6596DWR is RoHS non-compliant, which may present regulatory constraints in new designs or production environments with RoHS requirements.

For applications where RoHS compliance is mandatory, TPIC6595DWR or TPIC6B595DWR are the appropriate selections. For legacy systems or applications without RoHS constraints, either substitute maintains full parametric and functional equivalence. Inventory availability favors TPIC6595DWR with 19,473 units in stock, followed by TPIC6B595DWR with 17,504 units.

Frequently Asked Questions (FAQ)

Q: Can TPIC6595DWR and TPIC6B595DWR be used interchangeably with TPIC6596DWR?

A: Yes. Both substitute parts are parametrically equivalent across all critical specifications: logic configuration, output type, supply voltage, operating temperature range, package geometry, and functional capability. Direct substitution is supported without circuit modification.

Q: What is the difference between TPIC6595DWR and TPIC6B595DWR?

A: Both parts are functionally and parametrically identical. The primary distinction is the base product number designation (TPIC6595 versus TPIC6B595). Both maintain identical electrical performance, package form factor, and compliance certifications. Selection between these two can be based on inventory availability or supplier preference.

Q: Why is the TPIC6596DWR discontinued?

A: The TPIC6596DWR is listed as discontinued at DiGi Electronics. The active substitute parts TPIC6595DWR and TPIC6B595DWR provide equivalent functionality with improved compliance status (ROHS3 certification).

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the identical 20-SOIC package with 0.295" (7.50mm) width. Pinout and mechanical dimensions are equivalent, enabling direct board-level substitution.

Q: What compliance certifications apply to these substitute parts?

A: TPIC6595DWR and TPIC6B595DWR both carry ROHS3 compliance and REACH Unaffected status. Both parts have MSL rating of 1 (Unlimited) for moisture sensitivity. The original TPIC6596DWR is RoHS non-compliant but shares identical MSL and REACH status.
