Equivalent & Substitute Parts for TMPM 04253

Part Overview

The TMPM 04253 from Traco Power is an enclosed AC/DC converter, providing two outputs rated at 5V 600mA and 3.3V 150mA, with a universal input range of 85–264 VAC or 120–370 VDC and a maximum output power of 3.5W. It is designed for ITE (Commercial) applications and features through-hole mounting in a 7-DIP module package. The TMPM 04253 is currently obsolete, which necessitates identifying substitute models with equivalent electrical and mechanical parameters to ensure continued design compatibility and inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on matching essential electrical and mechanical parameters that define compatibility within the AC/DC converter category. Selection is based on the following key criteria:

• Number of outputs
• Input voltage range
• Output voltage and maximum current ratings
• Maximum power rating
• Package type and physical dimensions
• Operating temperature range
• Mounting type
• Applicable regulatory compliance (RoHS, REACH, agency approvals)
• Product status

Only parts that match these explicit values are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Due to the obsolete status of TMPM 04253, substitute selection must rely solely on equivalent parameters and maintained compliance statuses. TMLM 04253 matches all provided key attributes within the AC/DC converter category, including output configuration, input range, power rating, mounting type, physical package, and regulatory compliance. Both parts hold ROHS3 and REACH approvals. Differences in product status and certain approval agency listings should be noted relative to application requirements.

Frequently Asked Questions (FAQ)

Q: What determines whether TMLM 04253 is a suitable replacement for TMPM 04253?
A: Suitability is determined by matching output configuration, input voltage range, current ratings, power rating, package type, mounting method, physical dimensions, and regulatory compliance, as listed in the provided parameters.

Q: Does the substitute TMLM 04253 fit in the same physical footprint as TMPM 04253?
A: Both parts specify identical dimensions and 7-DIP module packages, supporting direct mechanical replacement.

Q: Are there differences in approval agencies between the two models?
A: TMPM 04253 lists CB, CE, cULus, and cURus approvals, while TMLM 04253 lists CE and cURus. Users should verify agency requirements based on provided certification data.

Q: Is the efficiency specification the same for both parts?
A: TMPM 04253 lists efficiency at 72%, while TMLM 04253 specifies 69% efficiency.

Q: What packaging differences exist between TMPM 04253 and TMLM 04253?
A: TMPM 04253 does not specify packaging; TMLM 04253 specifies "Box" packaging. Both parts use the same module package for installation.

Q: Is the input voltage range identical for both models?
A: TMPM 04253 supports 85 ~ 264 VAC, while TMLM 04253 supports 90 ~ 264 VAC; both allow 120 ~ 370 VDC input.
