ISA2412-TR Equivalent & Substitute Parts

Part Overview

The ISA2412-TR is an isolated module DC-DC converter manufactured by XP Power, designed to provide dual output voltages of +12V and -12V from a 21.6V to 26.4V input supply. This 1W converter is classified as an obsolete product, though 694 units remain in stock as new original inventory. The part is surface-mounted in a compact 10-SMD module package with 6 leads and operates across an industrial temperature range of -40°C to 105°C.

Due to the obsolete product status of the ISA2412-TR, identification of active equivalent parts is necessary to ensure long-term design continuity and supply chain reliability. Substitute parts must maintain electrical compatibility across input voltage range, output voltage specifications, current capacity, isolation rating, and mechanical form factor.

Regulatory and Compliance Status: The IAS0124D12 carries CE, UKCA, and UL approvals and conforms to standard 62368-1, providing enhanced regulatory coverage. Both parts maintain ROHS3 compliance.

Performance Enhancement: The substitute delivers 83% efficiency compared to 81% in the original part, representing a 2% improvement in power conversion efficiency.

Frequently Asked Questions (FAQ)

Q: Can the IAS0124D12 be used as a direct replacement for the ISA2412-TR in existing designs?

A: Yes. The IAS0124D12 is electrically and mechanically equivalent to the ISA2412-TR. All electrical parameters, including input voltage range (21.6V to 26.4V), output voltages (+12V and -12V), output current (42mA per channel), and isolation voltage (1.5 kV) are identical. The package configuration and mounting type are also identical, enabling direct substitution in PCB layouts.

Q: Are there any dimensional differences between these parts?

A: The IAS0124D12 has a maximum height of 0.29 inches (7.3mm) compared to 0.28 inches (7.0mm) for the ISA2412-TR. This 0.01-inch variance is within standard manufacturing tolerances and does not affect mechanical compatibility or PCB assembly. Length and width dimensions are identical at 0.60 inches and 0.33 inches respectively.

Q: What is the difference in efficiency between the ISA2412-TR and IAS0124D12?

A: The IAS0124D12 operates at 83% efficiency compared to 81% for the ISA2412-TR. This 2% improvement reduces power dissipation and thermal load in the application circuit.

Q: Why is the ISA2412-TR classified as obsolete?

A: The ISA2412-TR has been discontinued by XP Power and replaced by the IAS0124D12 in the active product line. The IAS0124D12 provides equivalent functionality with enhanced regulatory approvals and improved efficiency.

Q: What regulatory approvals does the substitute part carry?

A: The IAS0124D12 carries CE, UKCA, and UL approvals and conforms to standard 62368-1. The original ISA2412-TR does not list specific approval agencies in its specifications.

Q: Is the packaging different between these parts?

A: The ISA2412-TR is supplied in standard packaging, while the IAS0124D12 is supplied in Tube packaging. Both parts use identical 10-SMD Module, 6-lead package configurations suitable for surface mount assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both the ISA2412-TR and IAS0124D12 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the moisture sensitivity level of the substitute part?

A: The IAS0124D12 is rated as Not Applicable for moisture sensitivity level, indicating no special moisture handling requirements during storage or assembly.
