Engineering Selection Recommendations

LX432ISC (Microchip Technology) - Primary Substitute

The LX432ISC is the preferred substitute for the obsolete AP432SAG-7. This component maintains full electrical parameter equivalence with identical output voltage range (1.24V to 20V), current output (20 mA), tolerance (±1%), and cathode current (80 µA). The LX432ISC carries Active product status, ensuring long-term availability and supply chain continuity. The extended operating temperature range (-40°C to 85°C) provides broader environmental compatibility compared to the LX432CSC. Both components share identical SOT-23-3 packaging and surface mount configuration, enabling direct PCB-level substitution. RoHS3 compliance and REACH unaffected status maintain regulatory alignment with the original AP432SAG-7.

LX432CSC (Microchip Technology) - Secondary Substitute

The LX432CSC provides functional equivalence with identical electrical specifications (1.24V to 20V output, 20 mA current, ±1% tolerance, 80 µA cathode current) and SOT-23-3 packaging. However, this component carries Obsolete product status and operates within a narrower temperature range (0°C to 70°C), limiting its suitability for applications requiring extended temperature performance. The LX432CSC remains compliant with RoHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can the LX432ISC directly replace the AP432SAG-7 in existing designs?

A: Yes. The LX432ISC maintains identical electrical parameters (1.24V to 20V adjustable output, 20 mA current, ±1% tolerance, 80 µA cathode current) and shares the same SOT-23-3 package configuration. No circuit modifications are required for direct substitution.

Q: What is the primary difference between the LX432ISC and LX432CSC?

A: The LX432ISC operates across an extended temperature range (-40°C to 85°C) and carries Active product status, while the LX432CSC operates within 0°C to 70°C and is Obsolete. For new designs and long-term supply assurance, the LX432ISC is the recommended choice.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the LX432ISC and LX432CSC are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original AP432SAG-7.

Q: Does packaging differ between the AP432SAG-7 and substitute parts?

A: No. All three components utilize the SOT-23-3 package (also designated TO-236-3 or SC-59), enabling identical PCB footprint compatibility and surface mount assembly processes.

Q: Why is the LX432ISC preferred over the LX432CSC?

A: The LX432ISC carries Active product status, ensuring continued manufacturing and availability, whereas the LX432CSC is Obsolete. Additionally, the LX432ISC supports a wider operating temperature range (-40°C to 85°C versus 0°C to 70°C), providing greater design flexibility for temperature-sensitive applications.

Q: Are there any electrical performance differences between the substitutes?

A: No. Both LX432ISC and LX432CSC provide identical electrical specifications: 1.24V minimum output voltage, 20V maximum output voltage, 20 mA output current, ±1% tolerance, and 80 µA cathode current. Differences are limited to product status and operating temperature range.
