Equivalent & Substitute Parts for PT6303C
Part Overview
Texas Instruments PT6303C is a non-isolated Point-of-Load (PoL) DC-DC converter module, providing a single 3.3V output at up to 3A, with an input voltage range of 9V to 26V. The PT6303C's product status is Obsolete, making it necessary for engineers to identify equivalent or substitute models with matching or compatible electrical and mechanical parameters for new designs and maintenance of legacy equipment.

Engineering Selection Recommendations
PT6303C is classified as Obsolete. Alternative selection is directed by inventory status, RoHS and REACH compliance, and identical or broader operating environment as defined in provided parameters. Substitute parts must remain within specified input/output voltage and current ratings, module type, package/case, and compliance documentation.
Frequently Asked Questions (FAQ)
Q1: What are the critical parameters when selecting a substitute for PT6303C?
A1: The critical parameters are input voltage range, output voltage, output current, number of outputs, operating temperature range, mounting type, package/case, and environmental compliance (RoHS, REACH).
Q2: Can the R-733.3D module be substituted for PT6303C based strictly on provided parameters?
A2: R-733.3D matches type, input voltage range, output voltage, current rating, number of outputs, operating temperature range, compliance, and package/case specifications.
Q3: Are the package types for PT6303C and R-733.3D mechanically equivalent?
A3: Both are described as 12-SIP modules; PT6303C uses a surface mount version, while R-733.3D specifies through hole, right angle mounting.
Q4: Is there any difference in environmental compliance requirements?
A4: Both PT6303C and R-733.3D are ROHS3 Compliant and REACH Unaffected.
Q5: Does the MSL differ between the parts?
A5: Both have an MSL of 1 (Unlimited).
