Equivalent & Substitute Parts Reference: TEL 15-4813

Part Overview

TEL 15-4813 (Traco Power) is an isolated module DC-DC converter with a single 15V 1A output and a wide 36V–75V input range, suitable for ITE (Commercial) applications. Its product status is "Not For New Designs," necessitating the identification of alternative models with matching electrical and mechanical parameters. Engineering substitution is required to maintain functional compatibility and compliance with existing designs where sourcing the original part becomes impractical.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly by matching the following key criteria:

• Isolated module DC-DC converter type.
• One output with identical voltage and current ratings (15V, 1A).
• Power rating of 15W.
• Voltage isolation of 1.5 kV.
• Matching input voltage range, mounting type, package/case, size/dimension.
• Compliance with ITE (Commercial) application standards.
• RoHS3 compliance.
• Mechanical compatibility (through-hole, DIP package) and identical size.

Substitution is permitted only where these primary electrical and mechanical parameters converge.

Parameter Comparison

Engineering Selection Recommendations

For TEL 15-4813, substitute selection is justified by its "Not For New Designs" product status. Both JCK1548S15 and JTH1548S15 are ROHS3 Compliant and listed as "Active," supporting direct substitution under regulatory requirements. Mechanical mounting, footprint, and electrical specifications conform across the compared models. Use only those substitute parts that match both the compliance certifications and documented mechanical parameters.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match for DC-DC converter substitution?
A1: Voltage and current ratings, input voltage range, power, voltage isolation, and number of outputs must be equivalent.

Q2: Are mechanical package and mounting type critical when selecting substitutes?
A2: Yes, substitutes must have the same package/case dimensions and mounting type for direct PCB replacement.

Q3: Is RoHS compliance mandatory for substitutions in regulated environments?
A3: Substituted parts must match the RoHS compliance level of the original part when required by application standards.

Q4: What is the impact of product status when selecting a replacement?
A4: "Not For New Designs" status requires selection of an active part to ensure future availability.

Q5: Do substitute parts listed offer identical input ranges for all applications?
A5: Substitute parts must have an input range that covers or matches the original part's input specification.

Q6: Are there differences in features among the substitute DC-DC converters?
A6: Features are documented per part number. Substitution is based only on allowed parameters and application requirements.

Q7: How should inventory levels influence substitution decisions?
A7: Inventory information indicates current availability but does not affect technical suitability. Only key technical parameters determine compatibility.
