VE-BWL-EX Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VE-BWL-EX is an isolated DC-DC converter module featuring a 28V output at up to 2.68A, designed for ITE (commercial) applications. It delivers up to 75W with a 3 kV isolation rating and incorporates multiple protection features including overcurrent, overtemperature, overvoltage, and short-circuit protection. With its obsolete status, identifying functionally and mechanically compatible substitute DC-DC converters is necessary to maintain sustained system operation and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the VE-BWL-EX DC-DC converter module is determined exclusively by matching the following key parameters: input voltage range (18V to 36V), output voltage (28V), output current (2.68A max), output power (75W), isolation voltage (3 kV), number of outputs (1), mounting type (through hole), package/case (full brick), efficiency (88%), protection features (OCP, OTP, OVP, SCP), compliance (ROHS3), and environmental ratings (operating temperature and REACH status). Substitution is allowed only where these parameters are identical or within the specified ranges.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided information, the main selection criteria are product status and regulatory compliance. The VE-BWL-EX is obsolete, whereas VE-BWL-EX-F1 is an active, ROHS3 compliant, and REACH unaffected part from the same series and manufacturer. Both parts are classified as EAR99 with the same HTSUS code. VE-BWL-EX-F1 is appropriate for selection as a substitute for the VE-BWL-EX in applications requiring matched compliance and certifications.

Frequently Asked Questions (FAQ)

Q1: What criteria must be met for a DC-DC converter to be considered an equivalent substitute?
A1: The substitute DC-DC converter must have the same input voltage range, output voltage, output current, output power, isolation voltage, number of outputs, mounting type, package/case, efficiency, protection features, environmental ratings, compliance (ROHS3, REACH), and applicable certifications.

Q2: Are there any physical differences between VE-BWL-EX and VE-BWL-EX-F1 that can affect direct replacement?
A2: Both parts use the full brick package type, but size/dimension details show differences. VE-BWL-EX: 4.60" L x 2.40" W x 0.50" H; VE-BWL-EX-F1: 4.60" L x 1.86" W x 0.79" H. Mechanical compatibility must be verified against allowed installation tolerances based on the provided dimensions.

Q3: How is compliance ensured when substituting obsolete power modules?
A3: Both VE-BWL-EX and VE-BWL-EX-F1 are ROHS3 compliant and REACH unaffected, with the same ECCN and HTSUS codes. Selection can be based on these objective compliance parameters.

Q4: Is it necessary to consider the operating temperature range or environmental rating in substitution?
A4: Both parts feature the same operating temperature range of -10°C to 85°C and the same environmental status in terms of REACH, ensuring compatibility within the specified application environment.
