Traco Power TEN 15-4821 Equivalent & Substitute Parts Reference

Part Overview

The Traco Power TEN 15-4821 is a DC-DC converter, isolated module type, providing two outputs (5V and -5V, each at 1.5A), with a power rating of 15W and an input voltage range of 36V to 75V. It features overcurrent protection (OCP), overvoltage protection (OVP), and short circuit protection (SCP), is ROHS3 compliant, and is supplied in a 5-DIP module package for through-hole mounting. The series (TEN 15) is currently marked as "Not For New Designs," requiring identification of direct substitutes or equivalents that match the specified key electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converters for Traco Power TEN 15-4821 are strictly selected based on the following allowed electrical and mechanical parameters:

• Module type: Isolated
• Number of outputs: 2
• Input voltage range: 36V to 75V (or wider range, but must include 36V–75V)
• Output voltages: 5V and -5V
• Output current: 1.5A, 1.5A (per output)
• Power: 15W
• Voltage isolation: Minimum 1.5kV
• Features: OCP, SCP, OVP/UVLO as specified
• Efficiency: minimum 83%
• Operating temperature must cover at least -40°C to 85°C
• Package: Through Hole, 5-DIP Module or equivalent
• Size/dimensions: 2.00" x 1.00" x 0.40" (50.8mm x 25.4mm x 10.2mm)
• RoHS3 compliance

Substitutes are listed only if all these parameters meet or exceed those specified for TEN 15-4821.

Parameter Comparison

Engineering Selection Recommendations

• The Traco Power TEN 15-4821 is classified as "Not For New Designs," making identification of compatible, active replacements mandatory for continued engineering support.
• Both XP Power JCK1548D05 and JTH1548D05 substitute parts are ROHS3 compliant, satisfying lead-free and environmental directives.
• All compared models share suitable certifications such as ECCN: EAR99 and ITE (Commercial) application classification.
• Verify package compatibility, as JCK1548D05 uses 5-DIP Module packaging, matching the main part exactly, while JTH1548D05 applies a 6-DIP Module format.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for selecting a substitute for Traco Power TEN 15-4821?
A1: Substitute selection is based on matching or exceeding input/output voltage range, output current, power, isolation voltage, features, efficiency, through-hole mounting, package dimensions, number of outputs, compliance status, and application class.

Q2: Are there packaging differences among the listed substitutes?
A2: The XP Power JCK1548D05 uses the same 5-DIP Module package as TEN 15-4821, while the JTH1548D05 uses a 6-DIP Module package with the same exterior dimensions.

Q3: Are all substitute models compatible with ROHS3 requirements?
A3: Yes, all substitutes listed are ROHS3 Compliant.

Q4: What is the impact of input voltage range when substituting?
A4: Input voltage range must fully encompass the 36V to 75V specification of the TEN 15-4821 to ensure compatibility.

Q5: Does the isolation voltage differ between TEN 15-4821 and substitutes?
A5: TEN 15-4821 has 1.6 kV isolation; both listed XP Power substitutes provide 1.5 kV isolation, which is a closely-matched parameter.

Q6: Are there feature set differences between the models?
A6: TEN 15-4821 provides OCP, OVP, and SCP. JCK1548D05 provides OCP, SCP, and UVLO. JTH1548D05 offers OCP, OVP, SCP, and UVLO. Feature comparison should be reviewed for critical application requirements.

Q7: Can both substitutes be used with the same PCB footprint?
A7: JCK1548D05 matches the 5-DIP Module package type and footprint; JTH1548D05 uses a 6-DIP Module package with the same exterior dimensions, but pin compatibility should be checked against PCB layout.
