Equivalent & Substitute Parts Reference: DPBW03F-12

Part Overview

DPBW03F-12 from MEAN WELL USA Inc. is an active, isolated module DC-DC converter, delivering dual outputs of +12V and -12V at a maximum 125mA each, with a total power rating of 3W and wide input range (9V to 36V). The device targets commercial ITE applications, featuring remote on/off, over-current protection (OCP), short-circuit protection (SCP), and under-voltage lockout (UVLO). The need for substitute or equivalent models arises from system design flexibility, multi-sourcing strategies, and supply chain assurance. Equivalents must strictly match both the electrical and mechanical parameters specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for DC-DC converters are defined strictly by key electrical and mechanical parameters: output voltages, output current ratings, input voltage range, isolation voltage specification, power rating, number of outputs, operating temperature limits, mounting type, and package dimensions. Compliance statuses (RoHS, MSL) and product activity are strictly maintained. All listed substitute models must match these values to qualify as functional alternatives for DPBW03F-12.

Parameter Comparison

Engineering Selection Recommendations

Both DPBW03F-12 and IP2412S are active, ROHS3 compliant, and rated MSL1 (Unlimited), permitting interchangeable use in commercial ITE applications where these compliance requirements are essential. They share matching electrical and mechanical specifications, with minor variation in isolation voltage and efficiency. Component selection should be determined strictly by required certification and active inventory consideration.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory parameters for substituting DPBW03F-12 in a design?
A1: Substitute parts must exactly match the input voltage range, output voltages, maximum output currents, power rating, isolation voltage, mounting type, package type, operating temperature range, RoHS status, MSL rating, and product status.

Q2: Does the package format of IP2412S match DPBW03F-12 for drop-in compatibility?
A2: Yes. Both use an 8-SIP Module with 7 leads, with nearly identical dimensions.

Q3: Are there differences in certifications between DPBW03F-12 and IP2412S?
A3: Both are ROHS3 compliant and MSL 1 (Unlimited). No differences in compliance are listed in the provided parameters.

Q4: How does isolation voltage affect substitution?
A4: Substitution is allowed as the isolation voltages are within the same magnitude (1.5 kV vs. 1.6 kV), matching category requirements.

Q5: Is efficiency a strict substitution criterion?
A5: Efficiency values are stated; selection must maintain the specified minimum value where critical for system needs.

Q6: What application categories are supported for substitution?
A6: Both main and substitute parts are specified for ITE (Commercial) use, thus are applicable as equivalents within this category.
