Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4465EXK-T is determined by strict alignment across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier topology: Class AB configuration
• Channel count: Single-channel (mono) output
• Supply voltage range: 2.4V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Application class: Microphone amplification

Mechanical Compatibility Criteria:

• Package type: 5-TSSOP / SC-70-5 / SOT-353
• Mounting method: Surface mount
• Moisture sensitivity: MSL 1 (Unlimited)

Regulatory & Compliance Criteria:

• REACH status: REACH Unaffected
• ECCN classification: EAR99
• HTSUS code: 8542.33.0001

Substitute parts must satisfy all electrical, mechanical, and regulatory parameters without exception. Packaging format (tape & reel versus alternative formats) does not affect functional substitution when all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

MAX4465EXK+T as Primary Substitute:

The MAX4465EXK+T is a direct functional equivalent to the MAX4465EXK-T. All electrical parameters, mechanical specifications, and regulatory classifications are identical. The substitute part maintains the same base product number (MAX4465), amplifier topology (Class AB), channel configuration (mono), supply voltage range (2.4V ~ 5.5V), and operating temperature range (-40°C ~ 85°C).

Compliance Advantage:

The MAX4465EXK+T carries an Active product status and ROHS3 compliance certification, whereas the main part is obsolete and RoHS non-compliant. For new designs or production runs subject to RoHS regulations, the substitute part satisfies current environmental and compliance requirements.

Packaging Consideration:

The MAX4465EXK+T is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. This packaging format does not affect electrical or mechanical compatibility and is compatible with automated pick-and-place equipment.

Supply Chain Reliability:

Current inventory of the MAX4465EXK+T (2330 pcs) is available through active distribution channels, whereas the obsolete MAX4465EXK-T has limited remaining stock (3246 pcs). The substitute part ensures long-term design support and component availability.

Frequently Asked Questions (FAQ)

Q: Can the MAX4465EXK+T replace the MAX4465EXK-T in existing designs without circuit modification?

A: Yes. The MAX4465EXK+T is electrically and mechanically identical to the MAX4465EXK-T. All electrical parameters, pin configurations, package dimensions, and functional specifications are equivalent. No circuit redesign or PCB layout changes are required.

Q: What is the difference between the MAX4465EXK-T and MAX4465EXK+T part numbers?

A: The suffix designates packaging format. The "-T" suffix indicates standard packaging, while the "+T" suffix indicates Tape & Reel (TR) format. Both parts contain identical die and functional specifications. The packaging format difference does not affect electrical performance or compatibility.

Q: Is the MAX4465EXK+T RoHS compliant?

A: Yes. The MAX4465EXK+T is ROHS3 compliant. The original MAX4465EXK-T is RoHS non-compliant. If your application or regulatory environment requires RoHS compliance, the substitute part satisfies these requirements.

Q: Are there any temperature or voltage rating differences between these parts?

A: No. Both parts operate across identical supply voltage ranges (2.4V ~ 5.5V) and temperature ranges (-40°C ~ 85°C). All electrical operating specifications are equivalent.

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

A: Both the MAX4465EXK-T and MAX4465EXK+T carry MSL 1 (Unlimited) moisture sensitivity classification. This indicates minimal moisture sensitivity and allows for standard handling and storage procedures without special desiccant requirements.

Q: Can I use the MAX4465EXK+T in high-volume production?

A: Yes. The Tape & Reel (TR) packaging format of the MAX4465EXK+T is optimized for automated surface mount assembly. This format is standard for high-volume manufacturing and is compatible with standard pick-and-place equipment and reflow soldering processes.

Q: What is the product status difference, and does it affect functionality?

A: The MAX4465EXK-T is classified as Obsolete, while the MAX4465EXK+T is Active. Product status does not affect electrical or mechanical functionality. However, Active status ensures ongoing manufacturer support, availability through distribution channels, and compliance with current regulatory standards.
