OKR-T/10-W12-C Equivalent & Substitute Parts Reference

Part Overview

The Murata Power Solutions Inc. OKR-T/10-W12-C is a Non-Isolated Point-of-Load (PoL) Module DC-DC converter with a single output voltage programmable from 0.591V to 6V, a maximum output current of 10A, a power output up to 50W, and an input voltage range of 4.5V to 14V. The module features Remote On/Off, Overcurrent Protection (OCP), Overtemperature Protection (OTP), Short Circuit Protection (SCP), and Undervoltage Lockout (UVLO). It is designed for commercial ITE applications, with a robust operating temperature range of -40°C to 85°C and is RoHS3 compliant. As this part is listed as "Last Time Buy," it is necessary to identify substitute models to ensure supply continuity for new and existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined exclusively by matching or exceeding all defined electrical, mechanical, and regulatory parameters for the DC-DC converter Non-Isolated PoL Module product category. Key parameters for substitution include input voltage range, output voltage range, output current, power rating, operating temperature, mounting type, package/case, protection features, control features, compliance status, and moisture sensitivity level. Only parts that meet or surpass these criteria are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

OKR-T/10-W12-C is marked as "Last Time Buy" while substitute part NSR010A0X4Z maintains an active product status. Both parts share RoHS compliance and MSL 1 (Unlimited) status. Selection may be guided by stock levels and current lifecycle status, as both parts are compliant and suitable for environmentally regulated applications as indicated by their RoHS and MSL certifications.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select an equivalent DC-DC converter Non-Isolated PoL Module for OKR-T/10-W12-C?
A1: Substitution is based on matching electrical parameters (input voltage range, output voltage range, output current, power rating), package/case type, mounting, protection and control features, operating temperature, compliance status, and moisture sensitivity level.

Q2: Are the substitute and original DC-DC modules physically compatible?
A2: Both the OKR-T/10-W12-C and its substitute NSR010A0X4Z utilize a 5-SIP Module package type with similar physical dimensions.

Q3: How do the electrical performances of the substitute parts compare?
A3: Both modules operate within the same input and output voltage and current ranges, with the substitute (NSR010A0X4Z) providing a slightly higher maximum power output and higher efficiency.

Q4: Are there differences in compliance and reliability certifications among these models?
A4: Both parts are RoHS compliant and rated at MSL 1 (Unlimited), matching environmental and moisture sensitivity requirements.

Q5: Can either part be used without changes to existing commercial ITE designs?
A5: Both parts are specified for ITE (Commercial) applications and share key mechanical and electrical parameters as provided.
