TPS3824-25DBVR Equivalent & Substitute Parts

Part Overview

The TPS3824-25DBVR is a single-channel power supply supervisor IC manufactured by Texas Instruments, designed for power management applications requiring reset signal generation and voltage monitoring. This device operates as a push-pull, totem pole output supervisor with active high/active low reset capability, housed in a SOT-23-5 surface mount package. The main part is currently in active product status with 31,187 units in stock. Substitute parts are identified when packaging format changes are required or when alternative manufacturers provide equivalent functional specifications within the allowed parameter tolerances for this supervisor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS3824-25DBVR is determined by strict equivalence across the following critical parameters:

• Single-channel voltage monitoring capability
• 2.25V voltage threshold setting
• Push-pull, totem pole output configuration
• Active high/active low reset functionality
• Operating temperature range of -40°C to 85°C
• Surface mount technology with SC-74A/SOT-753 package footprint
• ROHS3 compliance and REACH unaffected status
• Moisture sensitivity level 1 classification

Two substitute relationships are identified:

Parametric Equivalent (Packaging Format Change): TPS3824-25DBVT differs from the main part only in packaging format (Tape & Reel versus Cut Tape). All electrical and functional parameters remain identical. This part is designated Last Time Buy status.

Cross-Manufacturer Equivalent: APX824-23W5G-7 (Diodes Incorporated) provides functional equivalence with identical voltage threshold, output configuration, reset type, and operating temperature range. The reset timeout specification differs (140ms minimum versus 120ms minimum), and the supplier device package designation is SOT-25 rather than SOT-23-5, though both maintain the same SC-74A/SOT-753 physical footprint classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TPS3824-25DBVR remains the recommended choice for new designs. The part maintains active product status with robust inventory availability (31,187 units), ensuring long-term supply continuity and design support from Texas Instruments.

Packaging Alternative: TPS3824-25DBVT is suitable for applications where Tape & Reel packaging format is preferred over Cut Tape. This part carries identical electrical specifications and ROHS3/REACH compliance. However, Last Time Buy status indicates limited future availability; procurement should account for this lifecycle phase.

Cross-Manufacturer Alternative: APX824-23W5G-7 (Diodes Incorporated) is suitable when supply constraints on Texas Instruments parts necessitate alternative sourcing. This part maintains active product status and equivalent functional performance. The reset timeout specification of 140ms minimum (versus 120ms minimum on the TPS3824 series) must be evaluated against application timing requirements. All regulatory compliance certifications (ROHS3, REACH) are equivalent.

Frequently Asked Questions (FAQ)

Q: Can TPS3824-25DBVT be used as a direct replacement for TPS3824-25DBVR?

A: Yes. Both parts are identical in electrical function, voltage threshold, output configuration, and operating specifications. The only difference is packaging format (Tape & Reel versus Cut Tape). Footprint and pinout are identical. However, TPS3824-25DBVT is in Last Time Buy status, so long-term availability is limited.

Q: What is the key difference between TPS3824-25DBVR and APX824-23W5G-7?

A: Both parts provide equivalent single-channel voltage supervision at 2.25V threshold with push-pull totem pole output. The primary difference is the reset timeout specification: TPS3824-25DBVR specifies 120ms minimum, while APX824-23W5G-7 specifies 140ms minimum. Applications with strict reset timing requirements must verify this 20ms difference is acceptable. The manufacturer differs (Texas Instruments versus Diodes Incorporated), but regulatory compliance and operating temperature ranges are equivalent.

Q: Are the package footprints identical across all three parts?

A: Yes. All three parts use SC-74A/SOT-753 physical package classification and are surface mount devices. TPS3824-25DBVR and TPS3824-25DBVT use SOT-23-5 supplier device package designation, while APX824-23W5G-7 uses SOT-25 designation. Despite the different supplier package names, all three maintain the same physical footprint and pinout compatibility.

Q: Which part should be selected for new production designs?

A: TPS3824-25DBVR is the recommended choice for new designs due to active product status and high inventory availability. This ensures design support continuity and reliable long-term supply from Texas Instruments.

Q: Can APX824-23W5G-7 be used if TPS3824-25DBVR is unavailable?

A: Yes, provided the 140ms reset timeout (versus 120ms) is acceptable for the application. APX824-23W5G-7 maintains equivalent voltage threshold, output configuration, reset type, operating temperature range, and regulatory compliance. Functional compatibility should be verified against specific application timing requirements.
