TSRN 1-2490A Equivalent & Substitute Parts Reference

Part Overview

The TSRN 1-2490A is a DC-DC converter from Traco Power, designed as a linear regulator replacement with a single 9V/1A output provided over a 10.5V to 36V input range. It features through-hole mounting in a compact 3-SIP module package. Due to the product’s discontinued status at Digi-Key, sourcing alternative models is essential to ensure component availability, maintain design compatibility, and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is performed by identifying products that match the essential electrical, mechanical, and compliance parameters explicitly listed in the input for this product category. Key parameters dictating equivalence include input voltage range, output voltage and current, power rating, package type, mounting method, operating temperature, and compliance attributes such as RoHS and REACH status.

The following substitute part, TSR 1-2490, has been listed based strictly on these allowed and matched parameters.

Key parameters for substitution:

• Number of Outputs
• Voltage - Input (Min/Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Efficiency
• Operating Temperature
• Mounting Type
• Package / Case
• Size / Dimension
• Applications
• Compliance Status (RoHS, REACH)

Parameter Comparison

Engineering Selection Recommendations

Engineers should select substitute parts based on current product availability, RoHS compliance, and REACH status only. The TSR 1-2490 from Traco Power is an active status product, listed as ROHS3 compliant and REACH unaffected, providing assurance of ongoing supply and environmental compliance within the defined parameters.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for the TSRN 1-2490A to be substituted?
A1: The substitute must match input voltage range, output voltage/current, power rating, number of outputs, efficiency, mounting type, package/case, operating temperature, application, and compliance status.

Q2: Are there physical or package differences to consider?
A2: Both the TSRN 1-2490A and the TSR 1-2490 use a 3-SIP Module through-hole package. Verify dimensional compatibility as the overall size/dimensions are slightly different but use the same mounting style and package.

Q3: Is RoHS and REACH compliance maintained with the substitute?
A3: Yes. Both components are ROHS3 compliant and REACH unaffected.

Q4: Does the difference in input voltage minimum affect substitution?
A4: The minimum input voltage for the TSRN 1-2490A is 10.5V, while for the TSR 1-2490 it is 12V. This must be evaluated strictly against input requirements for the end application.

Q5: Is there any difference in features?
A5: The TSRN 1-2490A has OTP and SCP features, while the TSR 1-2490 lists only SCP within the provided data. Selection can only be based on the features explicitly listed.

Q6: What is the maximum operating temperature for both parts?
A6: Both devices specify an operating temperature range of -40°C to 85°C with derating.

Q7: Are both parts suitable for ITE (Commercial) applications?
A7: Yes. Both are designated for ITE (Commercial) applications according to the provided attributes.
