Equivalent & Substitute Parts: PMJ8418TP

Part Overview

Flex Power Modules PMJ8418TP is a non-isolated Point-of-Load (PoL) DC-DC converter with a single adjustable output (0.8–5.5V), supporting up to 26A output current, and operating from a 10.8V to 13.2V input range. As part of the PMJ 8000 (143W) series, this through-hole 13-DIP module targets ITE (Commercial) applications and is ROHS3 compliant. The product status is obsolete, making it necessary to identify direct electrical substitutions meeting the original mechanical and application requirements.

Substitute Part Grouping Explanation

Substitution is determined strictly by matching parameters: type (Non-Isolated PoL Module), number of outputs (1), input voltage range (overlapping), output voltage capability, output current capability, mounting type, package, application, operating temperature, and RoHS compliance. Only parts conforming to these parameters are considered suitable equivalents in this category.

Engineering Selection Recommendations

The PMJ8418TP is obsolete, while PTH12030LAH is listed as active and ROHS3 compliant. Both modules share ITE (Commercial) application suitability, through-hole mounting, 13-DIP module packaging, identical output current ratings, and meet operating temperature standards. Compliance with RoHS and commercial application requirements is confirmed for both models. Relevant certifications and approvals are documented in the original data.

Frequently Asked Questions (FAQ)

Q: What criteria are used to determine substitution suitability for the PMJ8418TP?
A: Substitution is based on strict matching of module type, number of outputs, supported input voltage range, supported output current, mounting type, package/case, application category, operating temperature, and RoHS compliance.

Q: Is the PTH12030LAH mechanically compatible with PMJ8418TP in existing designs?
A: Both are through-hole, 13-DIP modules with closely matching physical dimensions and mounting styles as provided in the available data.

Q: How do output voltage ranges impact substitution?
A: Substitute modules must support output voltage ranges required by the application. Provided substitute PTH12030LAH supports 0.8–1.8V, which is less than the range offered by PMJ8418TP (0.8–5.5V).

Q: Are there application or regulatory differences between these models?
A: Both modules are specified for ITE (Commercial) applications and are ROHS3 compliant.

Q: What operational environment considerations apply for both modules?
A: Both have a specified operating temperature range of -40°C to 85°C.
