LMV393IDRG4 Equivalent & Substitute Parts

Part Overview

The LMV393IDRG4 is a dual general-purpose comparator manufactured by Texas Instruments in 8-SOIC surface mount packaging. This device features open-collector output configuration and operates across a 2.7V to 5.5V supply voltage range, making it suitable for low-power analog signal comparison applications. The LMV393IDRG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain electrical compatibility across supply voltage, output type, and thermal operating range to ensure direct circuit replacement without redesign.

Substitute Part Grouping Explanation

Substitution of the LMV393IDRG4 is determined by the following critical parameters:

Electrical Compatibility Requirements:

Supply voltage range must encompass or match 2.7V ~ 5.5V
Output type must be Open-Collector or functionally equivalent (CMOS with open-collector capability)
Number of elements must equal 2
Package must be 8-SOIC surface mount
Operating temperature range must support -40°C ~ 85°C minimum

Acceptable Substitutes by Category:

Category A - Direct Equivalents (Texas Instruments LMV393 Series): Parts maintaining identical electrical specifications, output type, and supply voltage range. These include LMV393IDR, LMV393M/NOPB, and LMV393MX/NOPB, which differ only in packaging format (Cut Tape, Tube, or Tape & Reel) and product status (Active vs. Discontinued).

Category B - Cross-Manufacturer Equivalents (Diodes Incorporated): The AZV393MTR-G1 and LMV393S-13 provide functional equivalence with minor parameter variations. AZV393MTR-G1 maintains identical specifications with lower quiescent current (200µA vs. 250µA). LMV393S-13 offers improved propagation delay (450ns vs. 600ns) and extended operating temperature range (-40°C ~ 125°C) but requires verification of output type compatibility.

Category C - Enhanced Performance Alternatives (Analog Devices Inc./Maxim Integrated): MAX9022ASA+, MAX9022ASA+T, and MAX9077ESA+ provide superior electrical performance with rail-to-rail output capability, lower input offset voltage (1mV vs. 7mV), and reduced input bias current (0.003µA to 0.005µA vs. 0.25µA). These parts operate across extended supply voltage ranges and temperature specifications but feature different output architectures (CMOS/Rail-to-Rail or Push-Pull vs. Open-Collector).

Engineering Selection Recommendations

Primary Recommendation - Direct Replacement: LMV393IDR is the preferred substitute for LMV393IDRG4. This part maintains identical electrical specifications, open-collector output configuration, and operating temperature range. The LMV393IDR is currently in active production status with substantial inventory availability (20,247 pcs), ensuring supply chain continuity. Both parts are ROHS3 compliant with MSL 1 rating, supporting identical manufacturing and storage requirements.

Secondary Recommendation - Texas Instruments LMV393 Series: LMV393M/NOPB and LMV393MX/NOPB provide functional equivalence with active product status. These variants differ in packaging format (Tube and Tape & Reel respectively) and feature expanded output type specification (CMOS, Open-Collector, TTL). Quiescent current specification increases to 300µA maximum, representing a 20% increase from the original 250µA. Both parts maintain ROHS3 compliance and MSL 1 rating.

Cross-Manufacturer Alternatives: AZV393MTR-G1 (Diodes Incorporated) and LMV393S-13 (Diodes Incorporated) offer active product status with improved quiescent current performance (200µA maximum). LMV393S-13 provides superior propagation delay (450ns vs. 600ns) and extended operating temperature range (-40°C ~ 125°C). Both parts maintain ROHS3 compliance. AZV393MTR-G1 operates across 2.5V minimum supply voltage, requiring circuit verification for 2.7V minimum applications.

Enhanced Performance Alternatives: MAX9022ASA+, MAX9022ASA+T, and MAX9077ESA+ deliver superior electrical performance with significantly reduced input offset voltage (1mV vs. 7mV) and input bias current (0.003µA to 0.005µA vs. 0.25µA). These parts feature rail-to-rail or push-pull output architectures, fundamentally different from the open-collector configuration of LMV393IDRG4. Circuit redesign is required to accommodate output type differences. MAX9022 series supports extended operating temperature range (-40°C ~ 125°C) and dual supply operation (±1.25V ~ 2.75V). MAX9077ESA+ maintains -40°C ~ 85°C operating range matching the original part. All three parts are ROHS3 compliant with MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can LMV393IDR be used as a direct drop-in replacement for LMV393IDRG4?

A: Yes. LMV393IDR maintains identical electrical specifications, output type (open-collector), supply voltage range (2.7V ~ 5.5V), and operating temperature range (-40°C ~ 85°C). The primary difference is product status (Active vs. Discontinued) and packaging format. Both parts are pin-compatible in 8-SOIC surface mount configuration.

Q: What is the difference between LMV393M/NOPB and LMV393MX/NOPB?

A: Both parts are electrically identical with matching specifications. The difference is packaging format: LMV393M/NOPB is supplied in Tube packaging, while LMV393MX/NOPB is supplied in Tape & Reel (TR) format. Selection depends on manufacturing assembly requirements and volume needs.

Q: Can MAX9022ASA+ replace LMV393IDRG4 without circuit modification?

A: No. While both are dual comparators in 8-SOIC packaging, MAX9022ASA+ features CMOS rail-to-rail output architecture versus the open-collector output of LMV393IDRG4. Output type differences require circuit redesign, particularly in pull-up resistor configuration and load impedance matching. MAX9022ASA+ is suitable only for applications where rail-to-rail output performance is beneficial and circuit topology can be modified.

Q: Why does AZV393MTR-G1 specify 2.5V minimum supply voltage instead of 2.7V?

A: AZV393MTR-G1 is manufactured by Diodes Incorporated and features a lower minimum supply voltage specification (2.5V vs. 2.7V). For applications requiring 2.7V minimum operation, this part provides additional margin. However, circuits designed for 2.7V minimum must be verified to operate reliably at the lower 2.5V threshold.

Q: What is the significance of MSL rating differences between substitute parts?

A: LMV393IDRG4, LMV393IDR, and Maxim parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. AZV393MTR-G1 and LMV393S-13 carry MSL 3 (168 Hours) rating, requiring controlled storage conditions and bake-out procedures before reflow soldering. MSL 3 parts must be stored in dry conditions and opened packages must be processed within 168 hours of exposure to ambient humidity.

Q: Is LMV393S-13 suitable for applications requiring extended temperature operation?

A: LMV393S-13 supports operating temperature range of -40°C ~ 125°C, extending 40°C above the original LMV393IDRG4 specification (-40°C ~ 85°C). This part is suitable for high-temperature applications. However, propagation delay specification improves to 450ns (vs. 600ns), and quiescent current reduces to 200µA (vs. 250µA), providing additional performance benefits for temperature-extended operation.

Q: What inventory considerations apply to substitute part selection?

A: LMV393IDR offers the highest inventory availability (20,247 pcs), ensuring immediate supply. LMV393S-13 (5,343 pcs), LMV393MX/NOPB (4,363 pcs), and AZV393MTR-G1 (3,809 pcs) provide substantial stock. MAX9022ASA+T (3,250 pcs) and LMV393M/NOPB (3,315 pcs) support medium-volume requirements. MAX9077ESA+ (2,100 pcs) and MAX9022ASA+ (1,483 pcs) carry lower inventory levels. For high-volume production, LMV393IDR is the recommended choice based on availability and active product status.
