JCK1548S15 Equivalent & Substitute Parts Engineering Reference

Part Overview

The JCK1548S15 by XP Power is an isolated DC-DC converter module delivering 15V output at 1A with a 15 W power rating. It operates from a 36V to 75V input voltage, provides 1.5 kV isolation, and is designed for ITE (commercial) applications. The module features OCP, SCP, and UVLO protections, offers 89% efficiency, and supports through-hole mounting in a 5-DIP module package. As an active part with ROHS3 compliance and MSL 1 rating, the JCK1548S15 is available in high inventory. Identifying equivalent and substitute models is necessary to manage source flexibility, procurement risk, or multi-sourcing objectives.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are selected if all critical parameters match or fall within the allowed limits for this category. Matching is based strictly on:

• Input voltage range (must cover 36V)
• Output voltage (15V)
• Output current (1A)
• Power rating (15 W)
• Number of outputs (1)
• Isolation (minimum 1 kV)
• Features (OCP, SCP, or OVP/UVLO where present)
• Package/case and mounting type (5-DIP Module, Through Hole)
• Application suitability (ITE Commercial)
• Environmental compliance (ROHS3, MSL 1)
• Active product status

Other parameter differences (e.g., isolation voltage higher or operating temperature differing within category standards) are noted but not used for exclusion unless outside given parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active, ROHS3 compliant, and have an MSL rating of 1 (Unlimited). Each substitute model shares the same package/case type, mounting style, and ITE (Commercial) application qualification. There are no variant differences in compliance or product status that affect substitute selection within provided data.

Frequently Asked Questions (FAQ)

Q: What parameters are required to substitute JCK1548S15 in a design?
A: Substitute modules must match input voltage range (36–75V or close), output voltage (15V), output current (1A), power rating (15 W), number of outputs (1), and mounting/package type (5-DIP Module, Through Hole).

Q: Is package compatibility fully maintained among substitutes?
A: All listed substitutes use a 5-DIP Module package and through-hole mounting. Dimensional differences exist but package compatibility by type is maintained.

Q: Are there compliance or certification discrepancies among substitute models?
A: All parts are ROHS3 compliant and classified as MSL 1 (Unlimited). ECCN and HTSUS codes match.

Q: Do features differ among substitutes, and does this affect selection?
A: OCP, SCP, and similar protection features are present across all models, with some variation (e.g., OVP/UVLO).

Q: What is the implication of the input voltage range for substitute selection?
A: Substitute models have a slightly lower input voltage maximum (72V versus 75V) and must be matched to application voltage requirements within these ratings.

Q: Does the difference in isolation voltage or efficiency affect functional equivalence?
A: Isolation voltages are 1 kV for substitutes versus 1.5 kV for the original; efficiency is slightly lower. These aspects are presented for direct comparison without interpretive guidance.
