Equivalent & Substitute Parts for PT6314A

Part Overview

The PT6314A by Texas Instruments is a Non-Isolated Point-of-Load (PoL) Module DC-DC Converter designed to provide a regulated 1.5V output at up to 3A from a 9V to 17V input. The product is classified as obsolete, necessitating the identification of alternative or substitute models with compatible electrical and mechanical parameters to sustain legacy designs or for replacement in maintenance and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitute models are selected exclusively based on alignment with key functional, electrical, and regulatory parameters. These include output current rating, input voltage range, module type, output count, mounting method, package form factor, operating temperature range, RoHS and REACH compliance, MSL rating, and relevant export control and harmonized tariff classifications. All substitute parts must match these key parameters within the values provided.

Parameter Comparison

Engineering Selection Recommendations

Selection is determined by the product status, RoHS3 compliance, MSL 1 (Unlimited), and REACH unaffected status. Substitution is feasible where regulatory compliance and export control classifications (ECCN, HTSUS) are consistent with application requirements.

Frequently Asked Questions (FAQ)

Q1: What key criteria define an acceptable substitute for the Texas Instruments PT6314A?
A1: Key criteria include matching mounting type, package/case (12-SIP Module), type (Non-Isolated PoL Module), operating temperature range, output current rating, compliance with RoHS and REACH, MSL level, and regulatory classifications (ECCN, HTSUS).

Q2: Does the substitute part R-531.8DA have the same output voltage as the PT6314A?
A2: The R-531.8DA provides a 1.8V output, whereas the PT6314A provides 1.5V. Both parts offer a maximum output current of 3A.

Q3: Are the substitute and main part mechanically compatible?
A3: Both parts use a through hole, right angle mounting in a 12-SIP Module package.

Q4: What regulatory and compliance standards do both parts share?
A4: Both parts are ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), classified under ECCN EAR99, and share the same HTSUS code.

Q5: Is thermal performance equivalent between PT6314A and R-531.8DA?
A5: Both parts specify an operating temperature range of -40°C ~ 85°C.
