JCK2048S15 Equivalent & Substitute Parts Reference

Part Overview

The JCK2048S15 by XP Power is an active DC-DC isolated module converter designed for ITE (Commercial) applications, providing a single 15V output at up to 1.33A (20W rated power) from a 36V–75V input. When sourcing and inventory continuity are critical, identifying substitute models with compatible electrical, mechanical, and environmental parameters ensures form, fit, and function without redesign. Substitution may be necessary due to inventory availability, multisourcing, or supply chain optimization.

Key parameters for substitution:

• Input Voltage Range
• Output Voltage and Current
• Power Rating
• Isolation Voltage
• Application Suitability (ITE, Commercial)
• Protection and Control Features
• Mounting Type and Package Dimensions
• Environmental Ratings (Temperature, RoHS, MSL)

Parameter Comparison

Engineering Selection Recommendations

Both JCK2048S15 and SKA20C-15 are active, RoHS3 compliant, and have a Moisture Sensitivity Level of 1 (Unlimited). Their ECCN and HTSUS codes are equivalent. These compliance and regulatory attributes allow direct selection for applications requiring ongoing availability and certified sourcing in commercial environments.

Frequently Asked Questions (FAQ)

Q1: What is the most important criterion when selecting a substitute for JCK2048S15?
A1: The most important criteria are matching electrical parameters (input/output voltages, current, power), isolation voltage, package/mechanical dimensions, application suitability, and function-related features.

Q2: Can SKA20C-15 be mounted the same way as JCK2048S15?
A2: Both parts utilize a through-hole mounting style and 6-DIP module packaging.

Q3: Are the protection and control features equivalent?
A3: Both models provide remote On/Off, OCP (Over Current Protection), OVP (Over Voltage Protection), and SCP (Short Circuit Protection). The main part has UVLO (Under Voltage Lockout) as an additional feature.

Q4: Do the substitute parts comply with industry-standard environmental and regulatory requirements?
A4: Both parts are ROHS3 compliant and have MSL 1 ratings. They share equivalent ECCN and HTSUS codes.

Q5: Is there a notable difference in operating temperature or efficiency?
A5: JCK2048S15 supports an operating range up to 100°C and 91% efficiency. SKA20C-15 supports up to 85°C (with derating) and 88% efficiency.

Q6: Are dimensions and form factor directly compatible?
A6: Both parts share the same length and width (2.00" x 1.00"). SKA20C-15 has a slightly higher profile (0.44" vs 0.40").
