Equivalent & Substitute Parts Reference for JTL4048S12

Part Overview

The JTL4048S12 (XP Power) is an active DC DC converter designed for isolated module applications requiring a single 12V output at up to 3.35A within an 18V to 75V input range. It is typically deployed in ITE (Commercial) systems where a reliable, efficient, and isolated power supply is necessary. Identifying compatible substitute DC DC converters is important to ensure system continuity, supply chain flexibility, and adherence to application requirements, particularly when direct replacements are needed for procurement or lifecycle management.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC DC converters for the JTL4048S12 are identified strictly based on matching the following key electrical and mechanical parameters: output voltage (12V), output current (approx. 3.33A), power rating (40W), isolated module type, number of outputs (1), input voltage range, efficiency, mounting type (through hole), package/case form factor (8-DIP Module), and compliance certifications (RoHS3, ECCN, MSL). These criteria ensure functionally compatible alternatives for regulated DC power supply replacement within ITE (Commercial) environments.

Parameter Comparison

Engineering Selection Recommendations

All parts compared hold an active product status and share RoHS3 compliance, EAR99 ECCN classification, and a 1 (Unlimited) MSL, confirming compatibility regarding regulatory and safety standards. Each utilizes a through-hole 8-DIP module package. Both SKA40B-12 and SKA40C-12 are positioned for direct substitution, subject to input voltage range fit within specific application requirements.

Frequently Asked Questions (FAQ)

Q1: What input voltage range differences exist among the substitute DC DC converters?
SKA40B-12 accepts 18V to 36V, whereas SKA40C-12 covers 36V to 75V. JTL4048S12 operates across 18V to 75V, accommodating both ranges. Substitute selection requires matching input range to system requirements.

Q2: Are output voltage and current specifications consistent across models?
All listed parts deliver a regulated 12V output with comparable maximum output currents (JTL4048S12: 3.35A; SKA40B-12/SKA40C-12: 3.33A).

Q3: Is the form factor and mounting compatible?
All models are provided in an 8-DIP module package and designed for through-hole mounting. Size variations are minimal within each series.

Q4: Which compliance standards do all parts meet?
Each part is declared ROHS3 compliant, features an MSL rating of 1 (Unlimited), and holds EAR99 ECCN classification.

Q5: Do the substitute parts include necessary control and protection features?
All alternatives specify remote On/Off, OCP, OVP, and SCP features. JTL4048S12 specifies UVLO and enable features; SKA40 series does not explicitly list UVLO.

Q6: Are thermal operating ranges comparable?
JTL4048S12 supports -40°C to 85°C; SKA40B-12 and SKA40C-12 support -40°C to 80°C with derating. Ensure the application’s ambient environment fits these temperature specifications.
