Equivalent & Substitute Parts Reference for TSRN 1-2433

Part Overview

The Traco Power TSRN 1-2433 is a DC-DC converter designed as a linear regulator replacement. This module provides a single 3.3 V output at up to 1 A from an input voltage range of 4.6 V to 36 V, delivering up to 3.3 W of power with 87% efficiency. It is intended for ITE (commercial) applications and features over-temperature and short-circuit protection. The device is packaged in a 3-SIP through-hole module with compact dimensions. The TSRN 1-2433 has been discontinued at Digi-Key, making it necessary to identify suitable alternative or equivalent models with compatible electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitute models for the TSRN 1-2433 are identified strictly by verifying that they match or exceed key electrical and mechanical parameters: type (linear regulator replacement), number of outputs, input voltage range, output voltage, maximum output current, package, mounting style, operating temperature range, compliance status, and protection features. A substitute must match the core functionality while adhering to the allowed parameters and form factor to ensure compatibility within the application.

Key parameters used for grouping:

  • Type: Linear Regulator Replacement
  • Number of Outputs: 1
  • Voltage Input Range: Minimum and maximum
  • Output Voltage: 3.3 V
  • Maximum Output Current

Engineering Selection Recommendations

For applications previously using the Traco Power TSRN 1-2433, the Traco Power TSR 2-2433 provides a compatible substitute based strictly on electrical characteristics, pin-compatible 3-SIP module package, and the observed compliance with ROHS3 and REACH requirements. Selection should be confirmed with respect to product status; TSR 2-2433 is currently active. No deviations in mechanical or compliance parameters exist between listed models. Inventory availability is also noted as part of selection criteria.

Frequently Asked Questions (FAQ)

Q: What electrical parameters determine a valid substitute for the TSRN 1-2433?
A: Output voltage, input voltage range, maximum output current, number of outputs, and product type are primary electrical parameters for substitution.

Q: Are the package dimensions and mounting type compatible between TSRN 1-2433 and TSR 2-2433?
A: Both parts use the 3-SIP module package and through-hole mounting; width and height are consistent. Length is slightly different but remains within standard board arrangement.

Q: Is the protection feature set equivalent for TSRN 1-2433 and TSR 2-2433?
A: The TSRN 1-2433 provides over-temperature protection (OTP) and short-circuit protection (SCP). The TSR 2-2433 provides overcurrent protection (OCP) and SCP. Both supply short-circuit protection; additional protection types are specified in the part description.

Q: Are RoHS and REACH compliance statuses the same?
A: Both the TSRN 1-2433 and TSR 2-2433 are ROHS3 compliant and REACH unaffected.

Q: Can the substitute part deliver a higher output current without compromising compatibility?
A: The TSR 2-2433 offers up to 2A output current, which exceeds the maximum current of the TSRN 1-2433 without reducing output voltage range, mechanical compatibility, or compliance.

Q: Is the operating temperature the same for both models?
A: Yes, both modules are rated for -40°C ~ 85°C with derating, meeting standard requirements for ITE (commercial) applications.
