Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PFE1000F-48 are grouped exclusively by direct equivalency in key electrical and mechanical parameters. The primary parameters used for substitution are:

• Manufacturer and Series consistency
• Input voltage range (85 ~ 265 VAC)
• Output voltage (48V)
• Maximum output current (21A)
• Power rating (≥1000W)
• Number of outputs
• Functional features (Remote On/Off, Universal Input)
• Mounting type (Through Hole)
• Package / Case (21-DIP Module)
• Mechanical dimensions (6.30" x 3.94" x 0.53")
• Certification standards compliance (CE, cULus)
• Operating temperature range

Only parts matching all these criteria based on the given data are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between PFE1000F-48 and PFE1000FA-48 should be based on product lifecycle status and compliance requirements. The PFE1000F-48 is obsolete, and the PFE1000FA-48 is active with expanded certification coverage (including CE, cURus, TUV, and both 60950-1 and 62368-1 standards). The substitute part meets or exceeds all listed electrical, mechanical, and certification parameters.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting the PFE1000F-48 in my design?
A1: Key criteria are matching input voltage range, output voltage and current, power rating, single output configuration, package size, mounting method, and compliance with applicable certifications.

Q2: Is the PFE1000FA-48 form-factor compatible with the PFE1000F-48?
A2: Both parts share the 21-DIP module format and identical mechanical dimensions.

Q3: Are approvals and certifications identical between substitutes?
A3: The PFE1000FA-48 carries additional certifications, including TUV and 62368-1, beyond the CE and cULus coverage of the PFE1000F-48.

Q4: Can the substitute part be used in the same applications as the original?
A4: Both the PFE1000F-48 and PFE1000FA-48 are specified for ITE (Commercial) applications.

Q5: What packaging should be expected for the substitute?
A5: The PFE1000FA-48 is supplied in bulk packaging, while the original part specifies “-”, indicating no additional detail was provided. Both use through hole mounting.
