Equivalent & Substitute Parts Reference Page for IE2409SH

Part Overview

The IE2409SH, manufactured by XP Power, is an isolated DC-DC converter module providing a single 9V output at up to 111mA from a 21.6V to 26.4V input. It is suitable for ITE (Commercial) applications requiring compact power conversion with through-hole SIP packaging. The part is active, RoHS3 compliant, and available in inventory. Alternative models are required for design flexibility, multi-sourcing, or inventory continuity when the main part is unavailable.

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict adherence to the key electrical and mechanical parameters. Substitution between IE2409SH and SMU01N-09 is permitted where input voltage range, output voltage, output power, mounting type, package, and regulatory compliance directly match. Minor variations in output current, isolation rating, efficiency, and operating temperature are considered only if they do not violate the minimum requirements set by the main part. All substitutes in this category must be active, RoHS3 compliant, and physically compatible in terms of package and mounting.

Key parameters for substitution:

Input voltage range
Output voltage and power
Output current meets minimum requirement
Isolation voltage meets minimum requirement
Through-hole 4-SIP module form factor
Compatible operating temperature
RoHS3 compliance
Active product status

Engineering Selection Recommendations

Selection between IE2409SH and SMU01N-09 is permitted as both parts are actively available, compliant with RoHS3 requirements, and meet unlimited MSL criteria. Both models reside in the isolated DC-DC converter module category with through-hole, 4-SIP module packaging, facilitating direct footprint compatibility. Part status and compliance certifications are suitable for direct component substitution in regulated ITE (Commercial) environments.

Frequently Asked Questions (FAQ)

Q: What are the required parameters for substituting IE2409SH with SMU01N-09?
A: Substitution requires matching input voltage (21.6V–26.4V), output voltage (9V), output power (1W), mounting type (through hole), and package/case (4-SIP module). Regulatory compliance and product status must also be matched.

Q: Are there any dimensional differences affecting physical compatibility?
A: Both IE2409SH and SMU01N-09 use the 4-SIP module form factor. Minor differences in height (0.50" vs. 0.40") exist but do not affect footprint compatibility.

Q: Is the output current of SMU01N-09 sufficient for applications specified for IE2409SH?
A: The output current for SMU01N-09 is 110mA compared to 111mA for IE2409SH.

Q: Does the substitution affect RoHS or MSL regulatory requirements?
A: Both parts are ROHS3 compliant and meet MSL 1 unlimited criteria.

Q: Can SMU01N-09 be used in the same application environments as IE2409SH?
A: Both devices are rated for ITE (Commercial) applications and offer similar operating temperature ranges, supporting direct substitution in compatible environments.

Q: Do control features impact substitution in this category?
A: Provided data indicates no control features for IE2409SH; SMU01N-09 lists OCP and SCP. Substitution in this case is based on core electrical and mechanical parameters.
