Equivalent & Substitute Parts for ISJ1212A

Part Overview

The ISJ1212A from XP Power is an isolated module DC-DC converter providing a single regulated output of 12V at 83mA within a 10.8V to 13.2V input range. With a 1W output rating, 1.5 kV isolation, SCP (short circuit protection), and surface mount packaging, it is suitable for ITE (commercial) applications. The product status is marked as Obsolete, making it necessary to identify alternative models with equivalent electrical and mechanical characteristics to ensure continued system reliability and manufacturability.

Engineering Selection Recommendations

Selecting NTE1212MC as a substitute for ISJ1212A is justified based on the product status and compliance. ISJ1212A is Obsolete, necessitating an active alternative. NTE1212MC matches required ROHS3 compliance and key operational certifications listed in the input. Product form factor, input/output ratings, and operational temperature envelope correspond to category standards provided.

Frequently Asked Questions (FAQ)

Q: What are the key parameters for substituting ISJ1212A?
A: Substitution requires matching input voltage range, output voltage and current, output power, package type, surface mount compatibility, application category, operating temperature range, and compliance status.

Q: How should differences in isolation voltage and efficiency be considered?
A: Only parameters explicitly listed are considered for substitution. Isolation voltage and efficiency differences are presented for engineering review but do not affect suitability if within category constraints.

Q: Is mechanical compatibility guaranteed between ISJ1212A and its substitute?
A: The compared parameters include package type and size/dimension. Both parts are surface mount modules with similar form factors. Full pinout or PCB layout compatibility is not covered in the provided data.

Q: Why is NTE1212MC listed as a substitute?
A: NTE1212MC matches all mandatory substitution criteria based on the input parameters, and is currently active with sufficient inventory.

Q: Should compliance or certification status be taken into account?
A: Substitute parts must match ROHS3 compliance and any listed certifications for direct replacement within regulated environments.
