TPS3124J12DBVT Equivalent & Substitute Parts

Part Overview

The TPS3124J12DBVT is a single-channel supervisor IC with push-pull, totem pole output configuration, designed for power management and reset control applications. Manufactured by Texas Instruments in SOT-23-5 surface mount packaging, this component monitors a single voltage threshold at 1.08V with an active high/active low reset output and 100ms minimum reset timeout. The part is currently in Last Time Buy status, indicating limited future availability. Identifying equivalent and substitute parts ensures design continuity and supply chain resilience for applications requiring this supervisor functionality.

Substitute Part Grouping Explanation

Substitution of the TPS3124J12DBVT is determined by strict equivalence across the following critical parameters:

  • Voltage Monitoring: Single channel with 1.08V threshold
  • Output Stage: Push-pull, totem pole configuration
  • Reset Behavior: Active high/active low capability
  • Reset Timing: 100ms minimum timeout
  • Temperature Range: -40°C to 85°C operation
  • Package: SOT-23-5 (SC-74A, SOT-753) surface mount
  • Compliance: ROHS3 compliant, MSL 1, REACH unaffected

All identified substitute parts maintain identical electrical and mechanical specifications across these parameters. Substitution is valid based on parametric equivalence within the TPS3124 and TPS3125 base product families from Texas Instruments.

Engineering Selection Recommendations

TPS3124J12DBVR: This part is a direct parametric equivalent to the main part, differing only in packaging designation (reel variant). Product status is Active, providing superior long-term availability compared to the Last Time Buy status of TPS3124J12DBVT. Current inventory is 761 units. This part is recommended as the primary substitute for new designs or replenishment.

TPS3125J12DBVR: This part maintains all critical electrical and mechanical parameters identical to the main part. The TPS3125 base product family is functionally equivalent to TPS3124 within the specified parameter set. Product status is Active with the highest current inventory at 3608 units, providing optimal supply chain security. This part is suitable for immediate substitution.

TPS3125J12DBVT: This part is parametrically equivalent with Active product status, though inventory is lower at 904 units. The tape and reel packaging matches the main part designation. This part is suitable for substitution where packaging consistency with the original specification is required.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can TPS3124J12DBVR be used as a direct replacement for TPS3124J12DBVT?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications. The difference is packaging designation: DBVR indicates reel packaging, while DBVT indicates tape and reel. Both are surface mount SOT-23-5 packages suitable for automated assembly. The primary advantage of TPS3124J12DBVR is its Active product status versus Last Time Buy.

Q: What is the difference between TPS3124 and TPS3125 base product families?

A: Within the parameters specified for these parts, TPS3124 and TPS3125 are functionally equivalent. Both provide single-channel voltage monitoring at 1.08V threshold with push-pull totem pole output, 100ms reset timeout, and identical operating temperature range. Substitution between these families is valid based on the provided specifications.

Q: Are all substitute parts in the same package?

A: Yes. All parts listed use SOT-23-5 surface mount packaging (SC-74A, SOT-753 designation). Pin configuration and footprint are identical, enabling direct PCB substitution without layout modification.

Q: What is the significance of Last Time Buy status?

A: Last Time Buy indicates the manufacturer will discontinue production after a specified date. TPS3124J12DBVT and TPS3125J12DBVT are in this status. For long-term supply security, TPS3124J12DBVR or TPS3125J12DBVR are recommended, as both maintain Active product status with ongoing manufacturing support.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity level), and are REACH unaffected. Regulatory and environmental compliance is maintained across all substitutes.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design uses the SOT-23-5 package footprint and does not depend on specific base product family designation. All electrical parameters, reset behavior, and operating conditions are identical across the substitute list.
