Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching electrical ratings, package type, mounting methodology, and regulatory compliance parameters. The following were used as substitution criteria:

• Series and manufacturer alignment
• Matching input voltage range (36V–75V)
• Identical output voltage and maximum output current (28V, 12.5A)
• Power rating (350W)
• Voltage isolation rating (2.25kV)
• Operating temperature range (-40°C to 85°C)
• Efficiency (93%)
• Package and mounting form (9-DIP Module, 1/2 Brick, Through Hole)
• Feature set (remote control, protection functions)
• Regulatory and environmental compliance (MSL, REACH, ECCN)
• Physical size/dimensions
• Product status for lifecycle considerations

Only parts matching every provided parameter have been listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Component selection between PAH-28/12.5-D48PB-C and PAH-28/12.5-D48NB-C is determined by product lifecycle status and provided compliance attributes. The PAH-28/12.5-D48PB-C is obsolete, while the PAH-28/12.5-D48NB-C is listed as last time buy and is ROHS3 compliant. MSL, REACH, and ECCN status remain consistent. These factors should guide the use of substitute components in approved designs.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for substitution among DC-DC converter isolated modules?
A1: Substitution is based strictly on matching input voltage range, output voltage and current, power rating, package type, mounting method, voltage isolation, operating temperature, efficiency, protection and control features, and regulatory compliance attributes.

Q2: Is there any difference between Enable, Active High and Enable, Active Low control features?
A2: Both control features enable remote on/off functionality, but their activation logic differs. The substituted part uses Enable, Active Low, while the main part uses Enable, Active High.

Q3: Are the physical dimensions and mounting style the same between PAH-28/12.5-D48PB-C and PAH-28/12.5-D48NB-C?
A3: Yes, both parts share the same package, case, mounting style, and overall dimensions.

Q4: What is the impact of the product status (Obsolete vs Last Time Buy)?
A4: Obsolete status indicates end of production and limited availability. Last Time Buy status signals that limited procurement is possible before discontinuation. Selection should consider supply continuity.

Q5: Are both parts compliant with key regulatory and environmental standards?
A5: Both parts are listed with the same REACH status (REACH Unaffected), ECCN (EAR99), and moisture sensitivity level (MSL 1), ensuring consistency in compliance attributes. The substitute part is listed as ROHS3 compliant.

Q6: Are there any package considerations when selecting the substitute?
A6: Both parts are provided in tray packaging and 9-DIP Module, 1/2 Brick case, supporting drop-in replacement in mechanical design.
