PT6203C Equivalent & Substitute Parts Reference

Part Overview

PT6203C is a DC DC CONVERTER module manufactured by Texas Instruments, belonging to the PT6200 series. It is a non-isolated Point-of-Load (PoL) DC DC converter with a single output of 3.3V and a maximum output current of 2A, designed for ITE (Commercial) applications. The converter features a surface mount 12-SIP SMD Module configuration, operates efficiently at 85%, and supports a wide input voltage range from 7V to 26V. The product is currently listed as Obsolete, making it necessary to identify alternative or substitute models to ensure functionally equivalent designs or to maintain compatibility in both electrical and mechanical domains.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching essential electrical and mechanical parameters. For PT6203C substitutes, the following key parameters are strictly considered:

• Type: Non-Isolated PoL Module
• Number of Outputs: 1
• Voltage - Output 1: 3.3V
• Current - Output (Max): 2A
• Voltage - Input (Min/Max): must encompass or exceed original range
• Applications: Must match ITE (Commercial)
• Operating Temperature: full supported range without exception
• RoHS/REACH compliance

Mounting Type and Package / Case are included per provided information. Selection is based only on explicit parameter compatibility.

Parameter Comparison

Engineering Selection Recommendations

PT6203C is designated as Obsolete. R-723.3D is listed as Active and meets all provided compliance standards including ROHS3 and REACH, with identical MSL levels. Selection between these devices can be based directly on product status, regulatory compliance, and available certifications as supplied.

Frequently Asked Questions (FAQ)

Q1: What parameters are most important when considering PT6203C substitutes?
A1: The most important parameters are type, number of outputs, output voltage, output current, input voltage range, application, operating temperature, mounting type, package/case, and compliance certifications.

Q2: Are package and mounting types critical for substituting PT6203C?
A2: Yes. Package / Case and Mounting Type are core considerations for mechanical compatibility and assembly methods given in the provided data.

Q3: Is R-723.3D fully compliant with RoHS and REACH standards?
A3: R-723.3D is specified as ROHS3 Compliant and REACH Unaffected, matching all regulatory requirements provided for the PT6203C.

Q4: Are efficiency levels identical between PT6203C and R-723.3D?
A4: Efficiency differs (PT6203C: 85%, R-723.3D: 95%) but this is a provided parameter, not a selection criterion unless specified as minimum threshold.

Q5: How does product status affect substitute selection?
A5: PT6203C is Obsolete; therefore, selection of an active substitute such as R-723.3D aligns strictly with maintaining active supply and compliance.

Q6: Can substitute selection be made without additional technical evaluation?
A6: Selections are based solely on matching provided key electrical, thermal, and mechanical parameters, and compliance status. No further technical evaluation is introduced unless specified in the provided data.
