Equivalent & Substitute Parts Reference: ISQ0505A

Part Overview

ISQ0505A is a DC-DC converter manufactured by XP Power, categorized as an isolated module providing 1 output of 5V at up to 400mA from an input voltage range of 4.5V to 5.5V. With a 2W power rating and 6 kV isolation, it is designed for ITE (Commercial) applications and features surface-mount packaging. This product status is listed as "Obsolete" which necessitates the identification of alternative models to ensure continued design support and inventory sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based solely on the following key parameters: input voltage range, output voltage, output current rating, power rating, isolation voltage, operating temperature, mounting type, and RoHS compliance status. Only parts matching or exceeding the critical electrical, mechanical, and compliance values provided are considered acceptable substitutes for ISQ0505A.

Parameter Comparison

Engineering Selection Recommendations

ISQ0505A is listed as "Obsolete." REC3-0505SRW/H6/A/SMD-R is an active product and is also ROHS3 compliant. Both parts provide the same primary functionality and compliance status, supporting substitution where product lifecycle and RoHS compliance requirements must be met.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for substituting DC-DC converters in this category?
A1: Substitution requires alignment on input voltage range, output voltage, output current, power rating, isolation voltage, operating temperature, mounting method, and RoHS compliance.

Q2: Is pin-to-pin compatibility guaranteed between ISQ0505A and REC3-0505SRW/H6/A/SMD-R?
A2: Only parameters provided here confirm electrical and mounting compatibility. Package details such as number of leads and dimensions may differ and should be verified for mechanical fit.

Q3: Does a higher output current or power rating affect direct substitution?
A3: A substitute offering equal or higher output current and power is typically acceptable within provided parameter limits.

Q4: How does operating temperature range impact substitution?
A4: The substitute part must meet or exceed the required operating temperature minimum and maximum of the original part.

Q5: Why is RoHS compliance important for substitute selection?
A5: Both main and substitute parts are ROHS3 compliant, fulfilling regulatory and environmental standards necessary for direct replacement.
