Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the following parameters: converter type, number of outputs, input voltage range, individual output voltages, maximum output current per channel, total output power, voltage isolation rating, application classification, mounting type, and compliance status. Only parts meeting or exceeding these criteria are included as substitutes.

Key parameters considered:

• Type (Isolated Module)
• Number of Outputs
• Input Voltage Range
• Output Voltages (+12V, -12V)
• Max Output Current (per channel)
• Output Power (W)
• Isolation Voltage
• Application Type
• Mounting Type
• Compliance (RoHS, MSL, REACH)

Parameter Comparison

Engineering Selection Recommendations

The main part number PT4313A is designated as obsolete. Substitute part REC15-4812D/H2/M is listed with active product status and is ROHS3 compliant, MSL 1 (Unlimited), and REACH unaffected, matching the compliance and certification profile required. Recommendations are based strictly on the component's product lifecycle status and regulatory compliance as provided.
