Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4173TESA is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier type classification as current sense amplifier
• Single circuit configuration
• Bandwidth specification of 1.7 MHz
• Input bias current of 700 µA
• Input offset voltage of 300 µV
• Supply current of 420 µA
• Supply voltage range spanning 3V to 28V minimum and maximum
• Operating temperature range of -40°C to 85°C

Mechanical Equivalence Criteria:

• Surface mount mounting type
• 8-SOIC package with 0.154" (3.90mm) width specification

Compliance Considerations:

• RoHS compliance status
• REACH compliance status
• Moisture sensitivity level classification

Parts meeting all electrical and mechanical parameters are classified as direct substitutes. Variations in product status (obsolete versus active) and packaging format (tube versus alternative) do not affect functional equivalence but may impact procurement and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

The MAX4173TESA+ is a direct functional equivalent to the MAX4173TESA across all electrical and mechanical parameters. Both devices share identical specifications for bandwidth, bias current, offset voltage, supply current, supply voltage range, operating temperature, and package configuration.

Product Status Consideration: The MAX4173TESA carries obsolete status, while the MAX4173TESA+ is active. Selection of the MAX4173TESA+ ensures access to current manufacturing processes and ongoing supplier support.

Compliance Advantage: The MAX4173TESA+ achieves ROHS3 compliance, whereas the original MAX4173TESA is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the MAX4173TESA+ satisfies these requirements.

Packaging Consideration: The MAX4173TESA+ is supplied in tube packaging format. Designs currently utilizing the MAX4173TESA in standard packaging may require verification of tape-and-reel or tube format compatibility with existing assembly processes.

Both parts maintain identical moisture sensitivity level classification (MSL 1 - Unlimited), REACH compliance status, and ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX4173TESA+ be used as a direct replacement for the MAX4173TESA in existing designs?

A: Yes. The MAX4173TESA+ is electrically and mechanically equivalent across all specified parameters. Both devices feature identical bandwidth (1.7 MHz), bias current (700 µA), offset voltage (300 µV), supply current (420 µA), supply voltage range (3V to 28V), operating temperature range (-40°C to 85°C), and 8-SOIC package configuration. No circuit modifications are required.

Q: What is the difference between MAX4173TESA and MAX4173TESA+?

A: The primary differences are product status and compliance certification. The MAX4173TESA is obsolete and RoHS non-compliant. The MAX4173TESA+ is active and ROHS3 compliant. Packaging format differs (standard versus tube), but electrical and mechanical specifications are identical.

Q: Why should I select the MAX4173TESA+ over the MAX4173TESA?

A: The MAX4173TESA+ offers three advantages: active product status ensuring ongoing availability and manufacturing support, ROHS3 compliance for regulatory alignment, and current manufacturing processes. The MAX4173TESA, being obsolete, presents supply chain risk and lacks RoHS compliance certification.

Q: Are there any compatibility issues with the 8-SOIC package between these parts?

A: No. Both the MAX4173TESA and MAX4173TESA+ use identical 8-SOIC packaging with 0.154" (3.90mm) width. Pin configuration, footprint, and mechanical dimensions are equivalent. Assembly compatibility is maintained.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAX4173TESA and MAX4173TESA+ carry MSL 1 (Unlimited) classification, indicating unlimited shelf life under standard storage conditions without moisture bake requirements.

Q: Do both parts meet REACH compliance requirements?

A: Yes. Both the MAX4173TESA and MAX4173TESA+ carry REACH Unaffected status, indicating compliance with REACH regulatory requirements.
