Equivalent & Substitute Parts Reference for 78ST165VC

Part Overview

The Texas Instruments 78ST165VC is a non-isolated Point-of-Load (PoL) DC DC converter module, delivering a single 6.5V output at up to 1.5A from a 7V–30V input. This module is designed for ITE (Commercial) applications, incorporates OTP and SCP features, and utilizes a through-hole 3-SIP module package. The 78ST165VC has been designated as obsolete, making it necessary to identify alternative models for ongoing designs and maintenance needs.

Parameter Comparison

Engineering Selection Recommendations

Selection logic is based on the product status and compliance information provided. The 78ST165VC component is listed as obsolete, requiring the use of an alternative for production and ongoing availability. The PTN78000WAZ part is listed as active, and conforms to ROHS3 compliance, whereas the original 78ST165VC is RoHS non-compliant. Moisture Sensitivity Levels and REACH status should also be reviewed against specific compliance requirements for the target application. Only provided certifications and compliance should be referenced when making the selection.

Frequently Asked Questions (FAQ)

Q1: What defines the substitute compatibility for 78ST165VC?
A1: Substitute compatibility is strictly determined by the number of outputs, input voltage range, output voltage capabilities, output current, operating temperature, application suitability, module features, mounting type, package, and compliance status.

Q2: Does the PTN78000WAZ provide the same electrical output as the 78ST165VC?
A2: The PTN78000WAZ supports an adjustable output voltage covering the 6.5V required by the 78ST165VC with the same 1.5A maximum output current.

Q3: Are mounting types and packages directly interchangeable between 78ST165VC and PTN78000WAZ?
A3: No. The 78ST165VC uses a through-hole 3-SIP module package, while PTN78000WAZ utilizes a surface-mount 5-SMD module package.

Q4: Are there differences in environmental and compliance certifications between these parts?
A4: Yes. The 78ST165VC is RoHS non-compliant and REACH unaffected, while the PTN78000WAZ is ROHS3 compliant and REACH affected. Review application requirements for compliance alignment.

Q5: What are the supply status differences?
A5: 78ST165VC is obsolete, and PTN78000WAZ is listed as active with available inventory per provided input.
