78ST165HC Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments 78ST165HC is a non-isolated Point-of-Load (PoL) DC DC converter module with a 6.5V output and 1.5A maximum load capacity. Designed for ITE (Commercial) applications, it features through-hole, right-angle mounting in a 3-SIP module package. With Texas Instruments listing the 78ST165HC as obsolete, identifying an equivalent or substitute part with matching critical parameters is necessary to maintain existing designs, production continuity, or for repair purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Texas Instruments 78ST165HC are selected by closely matching the following key parameters: output voltage (6.5V), output current (1.5A), compatible input voltage range, mounting type (through hole, right angle), and 3-SIP module package. The application, operating temperature, features (OTP, SCP), and compliance certificates (RoHS3, REACH) are also required for direct interchangeability. Only parts explicitly specified as substitutes and matching these parameters are included. No technical assumptions or extrapolations are made.

Parameter Comparison

Engineering Selection Recommendations

Selection between Texas Instruments 78ST165HC and Recom Power R-78B6.5-1.5L should be based on product availability, RoHS3 compliance, and REACH status. The 78ST165HC is obsolete, while the R-78B6.5-1.5L is active and in production. Both parts are RoHS3 compliant, REACH unaffected, and have an MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q1: What criteria are used for the selection of equivalent or substitute DC DC converter modules?
Equivalent and substitute modules are selected based on matching output voltage, output current, input voltage range, package type, mounting configuration, features, operating temperature range, application type, and compliance certifications.

Q2: Are 78ST165HC and R-78B6.5-1.5L pin- and footprint-compatible?
Both parts are specified as 3-SIP modules with through-hole, right angle mounting; compatibility is based strictly on the provided package and mounting information.

Q3: How does product status affect substitute selection?
The Texas Instruments 78ST165HC is obsolete, so selection of active status substitutes such as the Recom Power R-78B6.5-1.5L ensures continued availability in inventory and long-term support.

Q4: Which environmental and compliance certifications must be reviewed?
Both the primary and substitute parts are ROHS3 compliant and REACH unaffected, and have an MSL of 1 (Unlimited), supporting direct interchange in regulated environments.

Q5: Can all parameters outside the key listed fields vary in substitute selection?
Only parameters explicitly provided are considered for equivalency; no substitutions based on inferred or missing information are allowed.
