TMLM 05103 Equivalent & Substitute Parts Reference
Part Overview
The Traco Power TMLM 05103 is an enclosed AC/DC converter delivering a single output of 3.3V at up to 1.25A and 4.1W continuous power. The device operates from a universal input range of 90 ~ 264 VAC or 120 ~ 370 VDC and is suitable for ITE (Commercial) applications. This model features through-hole mounting in a 4-DIP module case and is approved by CE and cURus. The TMLM 05103 has been designated as Obsolete, necessitating the identification of equivalent and substitute enclosed AC/DC converters with similar electrical performance, mechanical form factor, and regulatory certifications to maintain compatible operation in existing designs.

Substitute Part Grouping Explanation
Substitute parts are identified strictly based on matching or exceeding the following key parameters: input voltage range, output voltage, maximum output current, number of outputs, power rating, mounting type, case dimensions, regulatory approvals, application suitability, and environmental compliance. Only parts with explicit compliance to these parameters and equivalent certifications are considered for substitution. No additional criteria beyond the provided data are applied.
Key parameters for this category are:
- Input voltage range: must include 90 ~ 264 VAC and 120 ~ 370 VDC
- Output voltage: 3.3V single output
- Maximum output current and power rating
- Number of outputs: 1
- Enclosed type with through-hole mounting
- Comparable package dimensions and type
- Regulatory approvals: CE, cURus (additional CB/cURus or similar accepted)
- Application: ITE (Commercial) or similar industrial
- RoHS compliance
- Operating temperature range overlapping with main part

Engineering Selection Recommendations
Select substitute parts based on active status, RoHS3 compliance, and corresponding safety approvals (CE, cURus, CB). All listed substitutes provide at least one output at 3.3V with comparable electrical performance in enclosed, through-hole mounting modules. Confirm application and certification requirements are met according to the parameters listed.
Frequently Asked Questions (FAQ)
Q1: What key parameters must match when selecting a substitute for the TMLM 05103?
A1: The substitute must have the same input voltage range or wider, match the output voltage (3.3V), provide at least equal or higher output current and power rating, have the same number of outputs, and meet relevant mounting and case requirements. The substitute must also hold comparable regulatory and RoHS compliance.
Q2: Are there differences in package dimensions among the alternatives?
A2: Substitute parts use 7-DIP or 5-DIP module case types, with size variations. Confirm mechanical layout and pin compatibility with the original 4-DIP module as per assembly requirements.
Q3: How is approval agency compliance maintained with substitutes?
A3: Substitute models possess equivalent regulatory certifications, including CE and cURus. Some models also carry CB listing. Only devices with explicitly listed certifications are included.
Q4: Can any listed substitute be used as a direct drop-in?
A4: Review mounting style, package/case, and size/dimensions. Differences in DIP module type and dimensions may require layout adjustments despite electrical compatibility.
Q5: Are all substitute parts RoHS compliant?
A5: All substitutes listed are ROHS3 Compliant per provided information.
Q6: What operating environments are supported by these parts?
A6: All parts operate from -25°C, with maximum upper operating temperatures ranging from 60°C to 70°C, with derating as specified. Confirm temperature compatibility for the specific application environment.
