Substitute Part Grouping Explanation

Substitute parts for the AP393SL-13 are classified into three categories based on substitution type and electrical compatibility:

Direct Manufacturer Substitutes (Diodes Incorporated): Parts AP393ASG-13 and AP393SG-13 are manufactured by the same supplier and share the identical base product number AP393. These parts maintain the same 8-SOP package, surface mount configuration, and core electrical specifications including supply voltage range (2V ~ 36V / ±1V ~ 18V), input offset voltage (5mV to 8mV @ 5V), input bias current (0.25µA to 0.4µA @ 5V), and output current (16mA typical). The primary differences are output type configuration and product status (active versus obsolete).

Parametric Equivalents: The AP393SL-13 itself appears in the substitute list as a parametric equivalent, indicating identical electrical performance specifications within the same product family.

Manufacturer Recommended Alternatives: Parts from Rohm Semiconductor (BA10393F-E2, BA2903F-E2), Texas Instruments (LM193AH/NOPB, LM193H/NOPB, LM193QT, LM2903AVQDR), and UMW (LM193DR) provide functional equivalence with variations in package type, operating temperature range, and quiescent current specifications. These parts maintain compatibility across the critical parameters: dual-element general-purpose comparator architecture, 2V to 36V supply voltage range, open-collector output configuration, and 8-pin surface mount or through-hole packaging.

Engineering Selection Recommendations

For Direct Replacement with Active Product Status: AP393ASG-13 and AP393SG-13 from Diodes Incorporated are the primary alternatives to the obsolete AP393SL-13. Both parts maintain identical packaging (8-SOIC, 3.90mm width), surface mount configuration, and supply voltage specifications. AP393ASG-13 provides multi-output type compatibility (CMOS, DTL, ECL, MOS, Open-Collector, TTL) with marginally relaxed input offset voltage (8mV versus 5mV) and input bias current (0.4µA versus 0.25µA). AP393SG-13 offers open-collector output configuration with input offset and bias current matching the original specification. Both are ROHS3 compliant and maintain MSL 3 moisture sensitivity rating.

For Extended Operating Temperature Range: BA10393F-E2 and BA2903F-E2 from Rohm Semiconductor extend the operating temperature range to -40°C to 85°C and -40°C to 125°C respectively, compared to the original 0°C to 70°C specification. These parts maintain open-collector output configuration and equivalent electrical performance. BA10393F-E2 provides lower quiescent current (1mA versus 2.5mA) and is available in higher inventory quantities (105,300 pieces). Both Rohm parts feature MSL 1 (unlimited) moisture sensitivity, indicating superior moisture resistance.

For Through-Hole Applications: LM193AH/NOPB and LM193H/NOPB from Texas Instruments provide through-hole TO-99-8 metal can packaging for applications requiring traditional PCB assembly methods. Both maintain the 2V to 36V supply voltage range and open-collector, rail-to-rail output configuration. LM193AH/NOPB offers superior input offset voltage specification (2mV @ 30V) and extended operating temperature range (-55°C to 125°C). Both are ROHS3 compliant with MSL 1 rating.

For Surface Mount with Extended Temperature: LM193DR from UMW provides 8-SOIC surface mount packaging with extended operating temperature range (-55°C to 125°C) and reduced quiescent current (1mA). This part maintains compatibility with the original 8-SOIC package footprint and open-collector, rail-to-rail output configuration. Supply voltage range is slightly reduced (2V to 32V single supply, ±1V to ±16V dual supply).

For Compact Packaging: LM193QT from STMicroelectronics offers 8-UFDFN exposed pad packaging for space-constrained applications. This part maintains the dual-element comparator architecture and 2V to 36V supply voltage range with active product status and MSL 1 rating.

For Enhanced Output Current: LM2903AVQDR from Texas Instruments provides 20mA typical output current (versus 16mA in the original specification) while maintaining 8-SOIC surface mount packaging, 2V to 36V supply voltage range, and open-collector, rail-to-rail output configuration. This part is suitable for applications requiring higher output drive capability.

All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AP393ASG-13 directly replace AP393SL-13 in existing designs?

A: Yes. AP393ASG-13 maintains identical 8-SOIC packaging, surface mount configuration, and supply voltage specifications (2V ~ 36V / ±1V ~ 18V). The primary differences are input offset voltage (8mV versus 5mV @ 5V) and input bias current (0.4µA versus 0.25µA @ 5V), which are within acceptable tolerances for most general-purpose comparator applications. Verify that your circuit design accommodates these relaxed specifications before implementation.

Q: What is the difference between AP393SG-13 and AP393ASG-13?

A: AP393SG-13 features open-collector output type exclusively, while AP393ASG-13 supports multiple output types (CMOS, DTL, ECL, MOS, Open-Collector, TTL). Both maintain identical supply voltage range, input offset voltage (5mV and 8mV respectively), and quiescent current specifications. Select AP393SG-13 for open-collector-only applications; select AP393ASG-13 for designs requiring output type flexibility.

Q: Why do Rohm Semiconductor parts (BA10393F-E2, BA2903F-E2) have lower quiescent current?

A: Rohm parts specify 1mA maximum quiescent current compared to 2.5mA in the original AP393SL-13 and Diodes Incorporated alternatives. This represents improved power efficiency in the Rohm design. Both parts maintain equivalent functional performance and are suitable for battery-powered or low-power applications where quiescent current is a design constraint.

Q: Can I use through-hole LM193 parts (LM193AH/NOPB, LM193H/NOPB) as replacements for surface mount AP393SL-13?

A: No. LM193 through-hole parts use TO-99-8 metal can packaging, which is incompatible with surface mount PCB layouts designed for 8-SOIC packages. These parts are suitable only for designs using through-hole assembly methods. For surface mount replacement, use AP393ASG-13, AP393SG-13, or other 8-SOIC alternatives.

Q: What is the difference between 8-SOIC (3.90mm width) and 8-SOIC (4.40mm width) packages?

A: The primary difference is package body width. AP393SL-13 uses 8-SOIC with 3.90mm width, while Rohm parts (BA10393F-E2, BA2903F-E2) use 8-SOIC with 4.40mm width. These packages have different PCB footprints and are not directly interchangeable without PCB redesign. Verify footprint compatibility before selecting Rohm alternatives for existing designs.

Q: Is LM193DR suitable for applications requiring the full 2V to 36V supply voltage range?

A: LM193DR from UMW specifies a reduced supply voltage range (2V to 32V single supply, ±1V to ±16V dual supply) compared to the original AP393SL-13 (2V to 36V / ±1V to 18V). This part is suitable for applications operating within the LM193DR voltage range. For designs requiring the full 36V single supply capability, use AP393ASG-13, AP393SG-13, or other alternatives that maintain the original 2V to 36V specification.

Q: What does MSL 1 (Unlimited) versus MSL 3 (168 Hours) mean for component handling?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to ambient conditions (30°C, 60% relative humidity) before requiring baking. MSL 1 (Unlimited) components have no moisture sensitivity restrictions and can be stored indefinitely under standard conditions. MSL 3 (168 Hours) components must be baked if exposed to ambient conditions for more than 168 hours. Rohm and Texas Instruments parts feature MSL 1 rating, providing superior shelf-life and handling flexibility compared to the original AP393SL-13 (MSL 3).

Q: Can I use LM2903AVQDR for applications requiring higher output current?

A: Yes. LM2903AVQDR provides 20mA typical output current compared to 16mA in the original AP393SL-13. This part maintains 8-SOIC surface mount packaging, 2V to 36V supply voltage range, and open-collector, rail-to-Rail output configuration. Use LM2903AVQDR in applications where higher output drive capability is required for driving external loads or logic circuits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (AP393ASG-13, AP393SG-13, BA10393F-E2, BA2903F-E2, LM193AH/NOPB, LM193DR, LM193H/NOPB, LM193QT, LM2903AVQDR) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
