IL4805S Equivalent & Substitute Parts

Part Overview

The XP Power IL4805S is an isolated DC-DC converter in a 4-SIP module through-hole package, delivering 5V at up to 400mA output from a 43.2V–52.8V input range with 2W power capability. This module is designed for ITE (commercial) applications and is RoHS3 compliant. The product status is listed as Obsolete. As a result, identifying direct equivalent or substitute parts is critical for ongoing designs or maintenance requirements where precise electrical and mechanical compatibility is required.

Substitute Part Grouping Explanation

Substitute parts for the IL4805S DC-DC converter must match all critical electrical and mechanical parameters to ensure compatibility. These parameters include: input voltage range (43.2V to 52.8V), output voltage (5V), maximum output current (400mA), wattage (2W), isolation voltage (1 kV), number of outputs (1), package (4-SIP Module), mounting type (Through Hole), operating temperature range (-40°C ~ 85°C), efficiency (78%), size/dimensions, and RoHS compliance status.

Engineering Selection Recommendations

The IL4805S is obsolete, and XP Power provides no officially recommended substitutes. All alternative selections for this DC-DC converter must meet RoHS3 compliance, identical package/footprint, and the same qualified certifications and regulatory compliance as specified.

Frequently Asked Questions (FAQ)

Q1: What defines equivalency for IL4805S DC-DC converter substitutes?
A1: Only parts with identical input and output voltage ranges, output current, isolation voltage, power rating, package type, mounting, operating temperature range, and RoHS status are considered equivalent.

Q2: Can a substitute part with a different package or pinout be used?
A2: Only substitute parts with the exact 4-SIP Module through-hole package and identical mechanical dimensions are considered compatible.

Q3: How important is regulatory compliance such as RoHS3 status in substitution?
A3: Regulatory compliance (e.g., RoHS3) is a mandatory selection criterion matching the original part.

Q4: Why is the obsolete status of the IL4805S relevant for substitution?
A4: Obsolete status requires design engineers to seek alternatives to ensure continued supply and support for designs utilizing the IL4805S.

Q5: Where are MFR recommended substitutes for IL4805S?
A5: No manufacturer-recommended substitute parts are specified for IL4805S.
