Equivalent & Substitute Parts for JCK2048S12

Part Overview

The XP Power JCK2048S12 is an isolated DC-DC converter designed for ITE (Commercial) applications. It features a single output of 12V at up to 1.67A, 20W power rating, operates from a 36V to 75V DC input, and supports through-hole mounting in a 6-DIP module package. The product is currently active and compliant with RoHS3 standards. Finding alternative models may be necessary due to supply chain requirements, layout constraints, multisourcing strategies, or mechanical compatibility—strictly within defined specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict adherence to key electrical and mechanical parameters. For DC-DC converter isolated modules, substitution is validated solely based on:

• Input voltage range
• Output voltage and current
• Total output power
• Isolation voltage
• Package/case style and dimensions
• Mounting type
• Regulatory compliance (RoHS, MSL)
• Product status (Active)

Each substitute part listed meets these criteria within the supplied parameter set. No additional parameters are considered.

Parameter Comparison

Engineering Selection Recommendations

Selection between JCK2048S12 and SKA20C-12 can be performed based on shared product status (Active), RoHS3 compliance, and identical moisture sensitivity level (MSL 1, Unlimited). Both parts are categorized as isolated DC-DC converter modules and utilize 6-DIP through-hole mounting. Inventory levels and certification information indicate suitability for compatible sourcing and environmental standards.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for substituting isolated DC-DC converter modules?
A1: Substitution is determined by matching input voltage range, output voltage/current, output power, isolation voltage, package style, mounting type, regulatory compliance, and product status.

Q2: Are the package dimensions compatible between JCK2048S12 and SKA20C-12?
A2: Both parts use the 6-DIP module format with dimensions 2.00” L x 1.00” W. The height differs: 0.40” (JCK2048S12) versus 0.44” (SKA20C-12). Compatibility depends on height clearance requirements.

Q3: Do both parts provide similar features for control and protection?
A3: Features such as Remote On/Off, Over Current Protection (OCP), Over Voltage Protection (OVP), Short Circuit Protection (SCP) are present, as indicated for both models.

Q4: Are both parts RoHS compliant?
A4: Yes, JCK2048S12 and SKA20C-12 are listed as ROHS3 Compliant.

Q5: What mounting type do both modules use?
A5: Both use through-hole mounting and are supplied in tube packaging.

Q6: Is there any notable difference in operating temperature?
A6: JCK2048S12 operates from -40°C to 100°C, while SKA20C-12 operates from -40°C to 85°C with derating.

Q7: Is moisture sensitivity a selection concern?
A7: No, both have a Moisture Sensitivity Level (MSL) of 1 (Unlimited).

Q8: How is electrical compatibility defined for substitute selection?
A8: Matching input voltage range, output characteristics, isolation rating, and power rating strictly determines electrical compatibility within the substitute group.
