Equivalent & Substitute Parts for OKL-T/3-W12P-C

Part Overview

The OKL-T/3-W12P-C by Murata Power Solutions Inc. is an active, non-isolated Point of Load (PoL) DC-DC converter module designed for ITE (Commercial) applications. It is housed in a surface-mount 12-SMD package and delivers up to 3A output current from a 4.5V to 14V input, with an adjustable output voltage range of 0.591V to 5.5V and a 15W power rating. Key features include remote on/off, OCP, OTP, SCP, UVLO, and compliant with ROHS3 and REACH standards. Finding alternative models is necessary for design flexibility, supply chain risk mitigation, and maintaining production continuity in case of lead time constraints or inventory depletion.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching key electrical and mechanical parameters: output current, input voltage range, output voltage adjustability, mounting type, package size, functional features, compliance status, and operating temperature. Substitutes must be active, available, and fulfill all provided compliance and performance specifications for direct interchangeability within the same category (Non-Isolated PoL Module DC-DC Converters for ITE applications).

Parameter Comparison

Engineering Selection Recommendations

Both OKL-T/3-W12P-C and APTS003A0X4-SRZ are active, RoHS compliant, and have the same ECCN and HTSUS codes. The MSL rating differs (1 year for OKL-T/3-W12P-C, 4 weeks for APTS003A0X4-SRZ), which may impact handling and storage requirements. Ensure that compliance requirements (ROHS3, REACH, ECCN) and current product status meet project and regulatory needs.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting OKL-T/3-W12P-C with APTS003A0X4-SRZ?
A1: The critical substitution criteria are output current (3A), input voltage range (4.5V-14V), output voltage range (approximately 0.6V to 5.5V), power output (≥15W), surface mount capability, package size, control features, operating temperature (-40°C ~ 85°C), compliance with RoHS and ECCN EAR99, and similar application (ITE Commercial).

Q2: Are there differences in package or mounting that need to be accounted for?
A2: Both parts share the same surface mount type and nearly identical dimensions. However, the package pin counts differ (12-SMD vs 10-SMD).

Q3: Do features such as OCP, OTP, SCP, UVLO and control input match between the substitute parts?
A3: Both include Remote On/Off, OCP, OTP, UVLO, and Enable (Active High). The substitute does not list SCP in the input parameters.

Q4: Is the substitute part's compliance status suitable for regulated applications?
A4: Both parts are RoHS compliant and have an ECCN classification of EAR99.

Q5: Does the moisture sensitivity level (MSL) affect selection?
A5: The MSL differs: OKL-T/3-W12P-C is MSL 2 (1 Year), APTS003A0X4-SRZ is MSL 2A (4 Weeks). This impacts storage and board assembly processes.
