Equivalent & Substitute Parts Reference for ISJ0512A

Part Overview

The ISJ0512A by XP Power is an isolated module DC-DC converter designed for ITE (Commercial) applications, offering a single 12V output at up to 83mA from a 4.5V to 5.5V input, and provides 1W power with 1.5kV isolation. The module is surface-mount in a 14-SMD package and is ROHS3 Compliant with unlimited MSL. As the ISJ0512A-series part is obsolete, alternative parts with equivalent electrical and mechanical characteristics must be considered for continued manufacturing or maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISJ0512A are selected strictly on matching the following parameters:

• Output configuration (single output, 12V, 83mA)
• Input voltage range (4.5V – 5.5V)
• Power rating (1W)
• Isolation voltage (1.5kV)
• Package type and footprint (14-SMD Module, 7 Leads; surface mount)
• Application type (ITE Commercial)
• Operating temperature range (−40°C to +85°C)
• RoHS compliance
• Moisture Sensitivity Level (MSL) Only substitute parts with these attributes are included.

Parameter Comparison

Engineering Selection Recommendations

The ISJ0512A is marked as "Obsolete". Substitute part DCV010512P-U maintains equivalent key electrical and mechanical parameters, and both are ROHS3 Compliant, satisfying environmental and regulatory requirements. Pay attention to the different Moisture Sensitivity Level (MSL) values; original ISJ0512A is MSL 1 (Unlimited), while DCV010512P-U is MSL 3 (168 Hours). Both parts are suitable for ITE (Commercial) applications within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: What criteria must be met for a substitute DC-DC converter in this category?
A: Substitute parts must have an identical input voltage range, output voltage and current, power rating, isolation voltage, application suitability, surface mount package type, and meet the same compliance standards.

Q: Are there any notable differences in package size or footprint between ISJ0512A and DCV010512P-U?
A: Both parts use a 14-SMD Module, 7 Leads package; size differs slightly, with ISJ0512A at 0.77" x 0.26" x 0.20" and DCV010512P-U at 0.78" x 0.33" x 0.21".

Q: Can DCV010512P-U be used as a direct replacement?
