ISE0512A-H Equivalent & Substitute Parts

Part Overview

The ISE0512A-H is an isolated module DC-DC converter manufactured by XP Power, designed to convert 4.5V to 5.5V input to a regulated 12V output at 84mA maximum current. This 1W converter is rated for commercial ITE applications with an operating temperature range of -40°C to 105°C and includes short-circuit protection (SCP). The ISE0512A-H is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISE0512A-H is determined by the following critical parameters:

• Input voltage specification: 4.5V to 5.5V input range
• Output voltage specification: 12V regulated output
• Output current capacity: Minimum 84mA at rated load
• Power rating: 1W or higher
• Mounting type: Surface mount configuration
• Package compatibility: 8-SMD Module, 5 Leads form factor
• Operating temperature range: -40°C to 105°C
• Isolation voltage: Not a limiting factor for the main part; substitute parts may exceed this specification
• Regulatory compliance: RoHS3 compliance required

Substitute parts are grouped into two categories:

Category 1 – Direct XP Power Equivalents (IES Series): Active product line replacements with identical electrical specifications and improved isolation voltage ratings (1.5kV to 3kV). These parts maintain the same input/output voltage and current specifications with enhanced efficiency (83% vs. 80%).

Category 2 – Alternative Manufacturer (CUI Inc.): The PDS2-S5-S12-M-TR provides higher power capacity (2W) with doubled output current capability (167mA), maintaining identical input/output voltage specifications and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with active product status and manufacturer continuity:

IES0105S12, IES0105S12-H, and IES0105S12-H-TR are XP Power active products that provide electrical equivalence to the obsolete ISE0512A-H. All three maintain identical input/output voltage specifications and output current capacity. The IES series offers improved efficiency (83% vs. 80%) and higher isolation voltage ratings (1.5kV to 3kV). Selection between these three variants depends on isolation voltage requirements and approval agency certifications:

• IES0105S12: 1.5kV isolation, CE/TUV/UL approved, tube packaging
• IES0105S12-H: 3kV isolation, UL approved
• IES0105S12-H-TR: 3kV isolation, UL approved, tape reel packaging

For applications requiring higher output current capacity:

PDS2-S5-S12-M-TR (CUI Inc.) provides a 2W converter with doubled output current (167mA) while maintaining identical input/output voltage specifications and operating temperature range. This part is suitable for designs where the 84mA output current of the ISE0512A-H is insufficient. The PDS2-S5-S12-M-TR carries EN approval and RoHS compliance.

All substitute parts maintain surface mount configuration, 8-SMD Module 5-lead package compatibility, and -40°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can IES0105S12 be used as a direct replacement for ISE0512A-H?

A: Yes. The IES0105S12 provides electrical equivalence with identical input voltage range (4.5V–5.5V), output voltage (12V), and output current (84mA). The IES0105S12 is an active product with improved efficiency (83% vs. 80%) and higher isolation voltage (1.5kV). Physical dimensions differ slightly (13.2mm × 8.5mm × 7.3mm vs. 12.7mm × 8.3mm × 7.0mm), requiring PCB layout verification.

Q: What is the difference between IES0105S12, IES0105S12-H, and IES0105S12-H-TR?

A: All three parts share identical electrical specifications. The differences are: IES0105S12 has 1.5kV isolation and CE/TUV/UL approvals; IES0105S12-H has 3kV isolation and UL approval; IES0105S12-H-TR has 3kV isolation, UL approval, and tape reel packaging. Selection depends on isolation voltage requirements and packaging format.

Q: When should PDS2-S5-S12-M-TR be selected instead of IES series parts?

A: The PDS2-S5-S12-M-TR is selected when output current exceeds 84mA. This 2W converter provides 167mA maximum output current while maintaining identical input/output voltage specifications. Applications requiring higher power delivery or current capacity benefit from this higher-rated alternative.

Q: Are there package compatibility concerns when substituting these parts?

A: All substitute parts use 8-SMD Module, 5-lead surface mount packages. Physical dimensions vary slightly: IES series parts are 13.2mm × 8.5mm × 7.3mm compared to the original 12.7mm × 8.3mm × 7.0mm. The PDS2-S5-S12-M-TR matches the original length and width (12.7mm × 8.3mm) with slightly increased height (7.3mm). PCB layout verification is required to confirm clearance and trace routing compatibility.

Q: What regulatory compliance should be considered for new designs?

A: All substitute parts are RoHS compliant. For isolation voltage requirements, IES0105S12-H and IES0105S12-H-TR provide 3kV isolation with UL approval. IES0105S12 provides 1.5kV isolation with CE, TUV, and UL approvals. PDS2-S5-S12-M-TR provides 1.5kV isolation with EN approval. Select based on application isolation requirements and regional regulatory standards.

Q: Is the ISE0512A-H still available for procurement?

A: The ISE0512A-H is classified as obsolete. However, 680 pieces are currently in stock as new original inventory. For long-term design support and future procurement, transition to an active substitute part is recommended.
