Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped strictly by matching key functional and mechanical parameters. The parameters used for equivalence are product type (Isolated Module), number of outputs (1), input voltage range (36V–72V), output voltage (12V), maximum output current (≥833mA), power rating (10W), mounting method (Through Hole), package/case (5-DIP Module), and compliance status (RoHS3). Only parts matching these categories and having compatible dimensions are listed.

Parameter Comparison

Engineering Selection Recommendations

Both JCH1048S12 and SKE10C-12 are classified as active products and are ROHS3 compliant with MSL 1 (Unlimited). Both carry the same ECCN and HTSUS codes, support ITE (Commercial) applications, and feature OCP and SCP. For selection within regulated environments, their compliance documentation aligns with restricted substances mandates.

Frequently Asked Questions (FAQ)

Q1: What parameters are essential when considering a substitute for JCH1048S12?
A1: Key parameters include input voltage range, output voltage, output current, power rating, isolation voltage, mounting type, package/case format, and ROHS compliance.

Q2: Can SKE10C-12 be directly substituted for JCH1048S12 in the same PCB footprint?
A2: Both DC-DC converters use the 5-DIP Module through-hole package and have similar size and terminal layout, supporting compatible PCB designs.

Q3: Are there any significant compliance differences between JCH1048S12 and SKE10C-12?
A3: Both parts are ROHS3 compliant with MSL 1, ECCN EAR99, and share similar regulatory classifications.

Q4: How does the operating temperature range affect part substitution?
A4: JCH1048S12 supports an operating range from -40°C to 100°C, while SKE10C-12 operates from -25°C to 71°C with derating. The temperature range must be checked against application requirements.

Q5: Do the substitute and main part have matching electrical safety features?
A5: Both provide overcurrent protection (OCP) and short circuit protection (SCP) by specification.

Q6: What should be considered regarding output isolation?
A6: JCH1048S12 specifies a 1.5 kV isolation, while SKE10C-12 specifies 1 kV. Isolation requirements must be matched to system needs.
