Equivalent & Substitute Parts Reference for ALD12A48-SL
Part Overview
The ALD12A48-SL (ARTESYN / Advanced Energy) is an isolated module DC-DC converter specified for ITE (commercial) applications. It provides a single 5V output at up to 12A, supporting an input voltage range of 36V to 75V, with a maximum power output of 60W and an isolation rating of 1.5 kV. The product is surface mount, in a 1/16 brick package, and features integrated protection functions including OCP, OTP, OVP, UVLO, and remote on/off. The ALD12A48-SL is classified as obsolete, necessitating the identification of technically compatible substitute models for active product selection and ongoing system support.

Substitute Part Grouping Explanation
Substitute parts are identified strictly by matching key electrical and mechanical parameters: input voltage range, output voltage, output current, power rating, isolation voltage, application type, protection features, operating temperature range, mounting type, package dimensions, and compliance details. Only models meeting or exceeding the ALD12A48-SL performance within these defined parameters are listed. Substitute relationships are determined mechanistically, without inference beyond provided product data.

Engineering Selection Recommendations
Selection of substitute components is governed by product lifecycle, compliance, and certifications. ALD12A48-SL is obsolete; AVD75B-48S05TL is active and listed as RoHS compliant. Both parts share the same application, isolation rating, operating temperature range, mounting type, and input/output voltage specifications. The substitute part offers higher output current and power rating. Ensure moisture sensitivity levels are considered per specification for assembly and storage environments.
Frequently Asked Questions (FAQ)
Q: What are the primary electrical compatibility requirements for substituting ALD12A48-SL?
A: Substitute parts must match the input voltage range (36V–75V), output voltage (5V), and meet or exceed the output current (12A) and power (60W) requirements.
Q: Are the isolation voltage and operating temperature comparable between ALD12A48-SL and AVD75B-48S05TL?
A: Both models specify an isolation voltage of 1.5 kV and an operating temperature range of -40°C to 85°C.
Q: Is the surface mount package and outline consistent for direct replacement?
A: The substitute part, AVD75B-48S05TL, has compatible surface mount packaging, with similar mechanical dimensions. Module height varies minimally.
Q: What additional features differ between the parts?
A: Both models provide remote on/off, OCP, OTP, and OVP. ALD12A48-SL specifies UVLO; AVD75B-48S05TL does not.
Q: How should moisture sensitivity level (MSL) be factored?
A: ALD12A48-SL specifies MSL 1 (unlimited); AVD75B-48S05TL specifies MSL 3 (168 hours). Assembly process must be managed accordingly.
Q: Are both components compliant with RoHS and export control regulations?
A: AVD75B-48S05TL is RoHS compliant; both parts list ECCN as EAR99 and HTSUS as 8504.40.9580.
