Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX6165BESA are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Fixed output voltage of 5V
• 8-SOIC surface mount package (0.154", 3.90mm Width)
• Output current capability of 5 mA
• Operating temperature range compatibility
• Tolerance and noise specifications within acceptable ranges

The MAX6165BESA+ serves as a direct packaging variant substitute with identical electrical specifications but improved product status (Active vs. Obsolete) and RoHS3 compliance. The ADR293 series (ADR293ERZ, ADR293ERZ-REEL, ADR293GRZ, ADR293GRZ-REEL7) represents manufacturer-recommended alternatives from Analog Devices Inc., offering enhanced performance characteristics including lower supply current (20 µA vs. 120 µA), extended input voltage range (6V ~ 15V), and extended operating temperature range (-40°C ~ 125°C). These alternatives maintain the same 5V fixed output, 5 mA output current, and 8-SOIC package format, ensuring mechanical and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete MAX6165BESA, the MAX6165BESA+ provides the most direct substitution path. This variant maintains identical electrical specifications and operating parameters while offering Active product status and ROHS3 compliance, addressing regulatory and supply chain concerns associated with obsolete components.

For new designs or applications requiring enhanced performance and extended operational margins, the ADR293 series represents the manufacturer-recommended alternative. The ADR293ERZ and ADR293GRZ variants (available in Tube packaging) or their Tape & Reel counterparts (ADR293ERZ-REEL and ADR293GRZ-REEL7) deliver significant advantages including reduced supply current consumption (20 µA vs. 120 µA), extended input voltage range (6V ~ 15V vs. 5.2V ~ 12.6V), and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). All ADR293 variants maintain ROHS3 compliance and Active product status.

Selection between ADR293ERZ/ADR293ERZ-REEL (±0.06% tolerance) and ADR293GRZ/ADR293GRZ-REEL7 (±0.2% tolerance) depends on application-specific accuracy requirements. The ADR293ERZ series offers superior tolerance and lower noise performance, while the ADR293GRZ series provides cost-effective performance for applications with relaxed tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX6165BESA+ be used as a direct replacement for MAX6165BESA?

A: Yes. The MAX6165BESA+ maintains identical electrical specifications including 5V fixed output, ±0.1% tolerance, 5 mA output current, and 8-SOIC package format. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). Electrical and mechanical compatibility is complete.

Q: What are the key differences between ADR293ERZ and ADR293GRZ?

A: Both variants share the same 5V output, 5 mA current, 8-SOIC package, and extended operating temperature range. The primary differences are tolerance (±0.06% vs. ±0.2%), temperature coefficient (10 ppm/°C vs. 30 ppm/°C), and noise performance (15 µVp-p vs. 15 µVp-p at 0.1Hz to 10Hz). ADR293ERZ provides superior accuracy; ADR293GRZ offers broader tolerance specifications.

Q: Are packaging variants (Tube vs. Tape & Reel) electrically equivalent?

A: Yes. Tube and Tape & Reel packaging variants of the same part number (e.g., ADR293ERZ vs. ADR293ERZ-REEL) contain identical die and electrical specifications. Packaging differences affect handling, storage, and assembly processes only. Selection depends on manufacturing requirements and inventory management practices.

Q: What is the impact of extended operating temperature range on substitution?

A: The ADR293 series operates across -40°C ~ 125°C compared to MAX6165BESA's -40°C ~ 85°C range. This extended range provides additional operational margin and is fully backward compatible with applications designed for the narrower MAX6165BESA temperature range. No design modifications are required.

Q: Does the reduced supply current of ADR293 series affect circuit design?

A: The ADR293 series draws 20 µA supply current versus 120 µA for MAX6165BESA. This reduction improves power efficiency and reduces thermal load. No circuit modifications are required; the lower current consumption is a performance advantage with no compatibility concerns.

Q: Are all substitute parts RoHS compliant?

A: MAX6165BESA is RoHS non-compliant. MAX6165BESA+ and all ADR293 variants (ADR293ERZ, ADR293ERZ-REEL, ADR293GRZ, ADR293GRZ-REEL7) are ROHS3 compliant. For applications requiring RoHS compliance, ADR293 series or MAX6165BESA+ are required.
