DS33ZH11+ Equivalent & Substitute Parts

Part Overview

The DS33ZH11+ is a specialized data transport interface IC manufactured by Analog Devices Inc./Maxim Integrated in a 100-CSBGA (10x10) package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system design and maintenance. The part supports multiple supply voltages (1.8V, 2.5V, 3.3V) and operates as a serial interface for data transport applications. Due to its obsolete status, identifying compatible alternatives is essential for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS33ZH11+ is determined by the following critical parameters: interface category classification, mounting type (surface mount), RoHS3 compliance, and functional application domain (data transport/serial interface). The substitute parts listed below maintain compatibility within these constraints while offering active product status and improved availability.

The five qualified substitute parts are grouped by their primary functional application:

• DS110DF410SQE/NOPB (Texas Instruments): Ethernet interface variant, active status
• LMH1219RTWR (Texas Instruments): Cable equalization interface, active status
• PI4MSD5V9546AZYEX (Diodes Incorporated): Bus switch logic interface, last time buy status
• PTN3366BSMP (NXP Semiconductors): Video level shifter interface, active status
• Z85C3008PSG (Zilog): Bus interface variant, active status

All substitutes maintain ROHS3 compliance, surface mount technology, and MSL ratings of 1–3, ensuring compatibility with standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for the obsolete DS33ZH11+ must prioritize active product status and long-term availability. All listed substitutes maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing environments.

DS110DF410SQE/NOPB and LMH1219RTWR (both Texas Instruments, active status) offer the most favorable long-term procurement outlook. PTN3366BSMP (NXP Semiconductors, active status) provides an alternative with improved MSL rating (2 vs. 3). Z85C3008PSG (Zilog, active status) is suitable for through-hole mounting applications where surface mount technology is not required.

PI4MSD5V9546AZYEX (Diodes Incorporated) carries last time buy status and should be evaluated only if its specific functional characteristics align with application requirements and procurement timelines permit extended lead times.

Package geometry differences require PCB layout re-evaluation. The original 100-CSBGA footprint differs significantly from all substitute options, necessitating design modification and validation.

Frequently Asked Questions (FAQ)

Q: Why is the DS33ZH11+ obsolete and what does this mean for my design?

A: Obsolete status indicates the manufacturer has discontinued production and support. Substitute parts must be identified and qualified before the original part becomes unavailable in inventory. All listed substitutes are either active or last time buy status, ensuring procurement viability.

Q: Are all substitute parts pin-compatible with the DS33ZH11+?

A: No. The DS33ZH11+ uses a 100-CSBGA package, while substitutes range from 16-pin to 48-pin QFN packages and one 40-pin DIP option. Pin compatibility does not exist; functional equivalence is based on interface category and application domain only. PCB redesign is required.

Q: What is the difference between surface mount and through-hole mounting in these substitutes?

A: Five substitutes use surface mount technology (QFN packages), compatible with modern PCB assembly processes. Z85C3008PSG uses through-hole DIP mounting, suitable for legacy or manual assembly applications. Selection depends on manufacturing capability and design requirements.

Q: Do all substitutes support the same supply voltages as the DS33ZH11+?

A: No. The DS33ZH11+ supports 1.8V, 2.5V, and 3.3V. Substitutes vary: DS110DF410SQE/NOPB operates at 2.375V–2.625V; PI4MSD5V9546AZYEX supports 1.65V–5.5V; PTN3366BSMP requires 3.0V–3.6V; Z85C3008PSG operates at 4.5V–5.5V. Voltage compatibility must be verified against your system design.

Q: What is MSL rating and why does it matter?

A: Moisture Sensitivity Level (MSL) indicates how long a component can be exposed to ambient humidity before soldering. MSL 1 (unlimited) is most forgiving; MSL 3 (168 hours) requires careful handling. Four substitutes have MSL 1–2 ratings, offering better shelf-life tolerance than the original part's MSL 3 rating.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronics manufacturing.

Q: Which substitute should I choose for new designs?

A: For new designs, prioritize active status parts: DS110DF410SQE/NOPB, LMH1219RTWR, PTN3366BSMP, or Z85C3008PSG. Evaluate functional requirements (Ethernet, cable equalization, video shifting, or bus interface) against your application. Avoid PI4MSD5V9546AZYEX (last time buy) unless its specific bus switch functionality is essential.
