Equivalent & Substitute Parts for TDK-Lambda PH75F280-28

Part Overview

The TDK-Lambda PH75F280-28 is an isolated DC-DC converter module featuring a single 28V output at 2.7A, with a wide input voltage range of 200V to 400V and a maximum power rating of 75W. Key features include remote On/Off, over-current protection (OCP), and over-voltage protection (OVP). This product is currently obsolete, which necessitates identifying qualified alternative DC-DC converter modules with matching electrical and mechanical characteristics for ITE (Commercial) applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the following parameters:

• Input Voltage Range
• Output Voltage
• Output Current (Max)
• Power Rating
• Voltage Isolation
• Applications
• Features
• Mounting Type
• Package / Case
• Operating Temperature Range

Only DC-DC converter modules with identical or compatible values for the above are included as substitutes. Mechanical format and compliance are also considered.

Parameter Comparison

Engineering Selection Recommendations

Substitution is appropriate based on product status and compliance. The PH75F280-28 is classified as obsolete, requiring an active replacement for maintenance and design continuity. The VE-B6L-CX offers the same output voltage, comparable output current, compatible electrical ratings, and satisfies ITE (Commercial) application needs. Its compliance status is ROHS3 Compliant and REACH Unaffected, with an EAR99 ECCN and matching HTSUS code. Moisture sensitivity levels should be considered for assembly process compatibility.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting the PH75F280-28 DC-DC converter?
A1: Substitution requires matching input voltage range, output voltage, maximum output current, power rating, voltage isolation, application suitability, key features, mounting type, package or case, and operating temperature range.

Q2: Are the mechanical dimensions of VE-B6L-CX compatible with the PH75F280-28?
A2: While both use through-hole mounting, the VE-B6L-CX has a different 'Full Brick' size compared to the 'Module' size of the PH75F280-28. Mechanical fit should be verified against enclosure requirements and PCB layout.

Q3: Does the substitute part offer equivalent electrical protection features?
A3: VE-B6L-CX provides over-current protection (OCP) and over-voltage protection (OVP), matching the PH75F280-28, with additional features of over-temperature protection (OTP) and short-circuit protection (SCP).

Q4: Can the substitute part be used in the same ITE (Commercial) environments?
A4: Both parts are specified for ITE (Commercial) applications with identical voltage isolation levels.

Q5: How does the operating temperature range compare between the original and substitute part?
A5: PH75F280-28 operates from -20°C to 85°C, while VE-B6L-CX is rated for -25°C to 85°C.

Q6: What compliance and regulatory codes are relevant for both parts?
A6: Both parts have ECCN EAR99 and HTSUS 8504.40.9580 codes. VE-B6L-CX is additionally listed as ROHS3 Compliant and REACH Unaffected.

Q7: Is the moisture sensitivity level the same for both models?
A7: PH75F280-28 has MSL 1 (Unlimited). VE-B6L-CX is listed as Not Applicable for MSL. Moisture sensitivity should be evaluated based on the process environment.
