ISF0505A Equivalent & Substitute Parts Reference

Part Overview

ISF0505A from XP Power is an isolated module DC-DC converter, providing a single regulated 5V output at up to 200mA from an input range of 4.5V to 5.5V, with a 1W output power and 1 kV isolation. The device is surface-mounted in an 8-SMD module package, targeting ITE (Commercial) applications. The product is currently classified as Obsolete. Due to its discontinued status and ongoing requirement for DC-DC converters in systems supporting similar electrical and mechanical constraints, it is necessary to identify equivalent substitute models.

Key Parameters

Substitute Part Grouping Explanation

Parts are grouped as substitutes strictly when key parameters align with application requirements, electrical output, and mechanical format. Parameters determining substitution eligibility include: type (isolated module), input voltage range, output voltage and current, output power, isolation rating, output count, mounting type, package/case, size/dimension, and compliance to relevant RoHS status. All substitute decisions use only supplied attributes.

Parameter Comparison

Engineering Selection Recommendations

ISF0505A is classified as obsolete. IFS0105S05 holds the same manufacturer, function, output, and compliance, and is currently active. Both parts adhere to ROHS3 compliance and provide surface mount installation in 8-SMD module packaging. Substitute selections are validated by matching input/output voltage parameters, isolation rating, output current and power, and compliance status, including supplied agency approvals for IFS0105S05. No other criteria are introduced.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are relevant for ISF0505A?
Match input/output voltages, output current, output power, isolation rating, package/case, mounting type, application, and compliance status.

Q2: Is package size and mounting type identical between ISF0505A and IFS0105S05?
Both are 8-SMD modules for surface mount. Dimensional differences exist; confirm fit within application envelope.

Q3: Are RoHS compliance and application approval statuses maintained?
Both ISF0505A and IFS0105S05 are ROHS3 compliant. IFS0105S05 includes supplied approval certifications.

Q4: Is there any change in electrical performance when substituting with IFS0105S05?
Electrical output ratings match at 5V and 200mA, with a 1W power rating. Isolation increases from 1 kV to 1.5 kV as stated.

Q5: Can IFS0105S05 be used directly in applications designed for ISF0505A?
Selection is based strictly on matching input/output, current, package, and compliance parameters. Evaluate mechanical size compatibility as provided.
