Equivalent & Substitute Parts Reference: ISA0524

Part Overview

XP Power's ISA0524 is an isolated module DC-DC converter featuring dual outputs of +24V and -24V, each delivering up to 21mA from a 4.5V to 5.5V input, with a total output power of 1W. It is designed for ITE (commercial) applications requiring 1.5 kV isolation and is provided in a 10-SMD module, 6 leads package. This product is listed as obsolete. Due to its end-of-life status and continuing demand for this function and electrical profile, it is necessary to identify substitute models with matching electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching the following key parameters: type (isolated module), number of outputs (2), input voltage range (4.5V–5.5V), output voltages (+24V, -24V), output current capacity (21mA per output), total power (1W), isolation voltage (1.5 kV), operational temperature window (-40°C to +105°C), mounting style (surface mount), package form (10-SMD module, 6 leads), dimensional compatibility, and RoHS compliance. Only products meeting all listed parameters are eligible as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The ISA0524 is obsolete; therefore, selection must be based on active product status, identical RoHS compliance, and matching certifications when specified. IAS0105D24 is active, ROHS3 compliant, and has additional approval agency certifications (CE, TUV, UL). Both parts are suitable for ITE (commercial) applications and share similar packaging and mounting profiles, ensuring compliance with relevant regulatory and quality standards.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting ISA0524 with IAS0105D24?
A1: Substitute selection is based on matching electrical parameters (input/output voltages and currents, power rating, isolation), packaging (surface mount, 10-SMD module, 6 leads), operational temperature, regulatory compliance (RoHS3), and product status.

Q2: How does package compatibility affect interchangeability between ISA0524 and IAS0105D24?
A2: Both parts share the 10-SMD module, 6 leads package and similar physical dimensions, supporting direct replacement on existing designs requiring specific footprint and mounting style.

Q3: Are there differences in regulatory approvals between ISA0524 and IAS0105D24?
A3: IAS0105D24 provides additional approval agency certifications (CE, TUV, UL) compared to ISA0524.

Q4: What is the impact of efficiency specification when selecting a substitute?
A4: IAS0105D24 offers higher efficiency (85%) compared to ISA0524 (81%), fully within the replacement criteria for this category.

Q5: Should RoHS compliance be verified when substituting?
A5: Both ISA0524 and IAS0105D24 are RoHS3 compliant, satisfying environmental and regulatory requirements.

Q6: Does inventory level influence component substitution?
A6: Inventory status is not part of the formal substitution criteria and is not considered in engineering compatibility determination.
