MAX9017AEKA-T Equivalent & Substitute Parts

Part Overview

The MAX9017AEKA-T is a dual-channel comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This device features CMOS push-pull, rail-to-rail output architecture in a compact SOT-23-8 surface mount package. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and production continuity. Substitute parts must maintain electrical compatibility across supply voltage, input offset, bias current, output characteristics, and thermal operating range while accommodating different packaging formats and product status classifications.

Supply voltage range: 1.8V ~ 5.5V
Input offset voltage: ≤5mV @ 5V
Input bias current: ≤0.001µA @ 5V
Output current capability: ≥50mA typical
Quiescent current: ≤2.8µA maximum
PSRR: ≥80dB typical

Surface mount packaging

Substitutes are categorized into three groups:

Group 1: Direct Packaging Variants — Identical electrical specifications with alternative packaging formats (Cut Tape, Tape & Reel) or product grades (automotive-qualified). These maintain full pin-for-pin compatibility.

Group 2: Parametric Equivalents — Parts with single-channel configuration (MAX9015AEKA+T) or alternative temperature grades that meet or exceed the primary electrical requirements within the specified operating envelope.

Group 3: Manufacturer-Recommended Alternatives — Parts from alternative manufacturers (Advanced Linear Devices, Texas Instruments) that satisfy electrical performance criteria but may require package-level design accommodation or thermal/compliance verification.

Engineering Selection Recommendations

Tier 1 — Direct Replacement (Recommended for New Designs):

MAX9017AEKA+T, MAX9017AEKA/V+T, and MAX9017BEKA+T are active-status variants of the obsolete MAX9017AEKA-T. These parts maintain identical electrical specifications and SOT-23-8 packaging. MAX9017AEKA+T is available in Cut Tape & Digi-Reel format with 1040 units in stock. MAX9017AEKA/V+T carries automotive-grade qualification (AEC-Q100) and is suitable for temperature-critical applications. MAX9017BEKA+T is available in Tape & Reel format with 2600 units in stock. All three are ROHS3 compliant and carry identical REACH and ECCN classifications.

Tier 2 — Parametric Equivalents (Supply Voltage and Thermal Compatible):

MAX9015AEKA+T provides single-channel operation with identical electrical performance and active product status. This part is suitable for applications requiring only one comparator channel, offering lower quiescent current (2µA vs. 2.8µA) and higher inventory availability (10400 units). Thermal and supply voltage specifications remain unchanged.

TLV3492AIDCNR and TLV3492AIDCNT (Texas Instruments) maintain SOT-23-8 packaging and identical supply voltage range. These parts feature extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C) and lower quiescent current (1.2µA). Input offset voltage is higher (15mV @ 5.5V vs. 5mV @ 5V), and propagation delay is faster (14.6µs vs. 28µs). PSRR specification is lower (69.12dB vs. 80dB). These parts are suitable for applications where extended temperature operation is required and offset voltage tolerance permits.

Tier 3 — Alternative Packaging (Design Accommodation Required):

TLV3492AMDREP (Texas Instruments) provides 8-SOIC packaging with extended temperature range (-55°C ~ 125°C). Electrical specifications match TLV3492AIDCNR/AIDCNT variants. PCB layout and footprint redesign is required.

TLV3702IDGK (Texas Instruments, obsolete status) offers 8-VSSOP packaging with extended supply voltage range (2.7V ~ 16V, ±1.35V ~ 8V) and superior PSRR (105dB). Input offset matches the main part (5mV @ 15V). Output current is reduced (10mA vs. 50mA). This part is suitable only for low-current applications requiring extended supply voltage compatibility.

Tier 4 — General-Purpose Alternatives (Compliance Verification Required):

ALD2332ASAL and ALD2332PAL (Advanced Linear Devices) provide general-purpose dual-channel comparator functionality with different packaging (8-SOIC and 8-DIP respectively). Supply voltage range is narrower (4V ~ 10V, ±2V ~ 5V) and operating temperature is restricted (0°C ~ 70°C). Quiescent current is significantly higher (500µA vs. 2.8µA). These parts are suitable only for applications where the narrower supply voltage and temperature ranges are acceptable and power consumption constraints are relaxed.

Frequently Asked Questions (FAQ)

Q: Can MAX9015AEKA+T replace MAX9017AEKA-T in existing designs?

A: MAX9015AEKA+T is a single-channel variant with identical electrical specifications and packaging. It is suitable only for applications using one comparator channel. Designs requiring dual-channel operation must use two-element alternatives (MAX9017AEKA+T, MAX9017BEKA+T, or TLV3492 variants).

Q: What is the primary difference between MAX9017AEKA+T and MAX9017AEKA/V+T?

A: MAX9017AEKA/V+T carries automotive-grade qualification (AEC-Q100) and is suitable for automotive and temperature-critical applications. Both parts are electrically identical and use SOT-23-8 packaging. Selection depends on application requirements and qualification documentation.

Q: Are TLV3492 parts from Texas Instruments pin-compatible with MAX9017AEKA-T?

A: TLV3492AIDCNR and TLV3492AIDCNT are pin-compatible in SOT-23-8 packaging. However, electrical specifications differ: input offset voltage is higher (15mV vs. 5mV), propagation delay is faster (14.6µs vs. 28µs), and PSRR is lower (69.12dB vs. 80dB). Functional compatibility requires verification that these parameter differences do not affect circuit performance.

Q: Why is TLV3702IDGK listed as a substitute if it is obsolete?

A: TLV3702IDGK is included because it was originally listed in the MAX9017AEKA-T substitute database. However, its obsolete status and reduced output current (10mA vs. 50mA) make it unsuitable for new designs. It is retained for reference only in legacy system maintenance scenarios.

Q: What are the packaging format differences between substitute parts?

A: MAX9017 variants and TLV3492AIDCNR/AIDCNT use SOT-23-8 surface mount packaging. TLV3492AMDREP uses 8-SOIC surface mount. ALD2332ASAL uses 8-SOIC surface mount. ALD2332PAL uses 8-DIP through-hole. TLV3702IDGK uses 8-VSSOP surface mount. PCB footprint compatibility must be verified before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance status. REACH status is unaffected for all parts. ECCN classification is EAR99 for all parts listed.

Q: What is the inventory status for recommended substitutes?

A: MAX9017AEKA+T has 1040 units in stock. MAX9017AEKA/V+T has 1900 units. MAX9017BEKA+T has 2600 units. MAX9015AEKA+T has 10400 units. TLV3492AIDCNR has 3300 units. TLV3492AIDCNT has 2220 units. TLV3492AMDREP has 6032 units. Inventory levels should be verified with suppliers before procurement decisions.

Q: Can ALD2332 parts replace MAX9017AEKA-T?

A: ALD2332ASAL and ALD2332PAL provide dual-channel comparator functionality but have significant limitations: narrower supply voltage range (4V ~ 10V vs. 1.8V ~ 5.5V), restricted operating temperature (0°C ~ 70°C vs. -40°C ~ 85°C), and substantially higher quiescent current (500µA vs. 2.8µA). These parts are suitable only for applications where these parameter restrictions are acceptable.
