TRA 1-1212 Equivalent & Substitute Parts Reference

Part Overview

The TRA 1-1212, manufactured by Traco Power, is an isolated module DC-DC converter delivering a single 12V output at up to 84mA, with a 1W power rating. It accepts a 10.8V to 13.2V input, provides 1kV isolation, and is housed in a 6-SIP module for through-hole mounting. The product status is listed as "Not For New Designs," indicating that it is not recommended for new production builds. For ongoing or future designs, identifying substitute models with fully matched electrical and mechanical specifications is required for continued production or maintenance.

Substitute Part Grouping Explanation

Substitute part selection for isolated module DC-DC converters is governed strictly by matching the following parameter set: input voltage range, output voltage and current, total output power, isolation voltage, package type, mounting method, compliance data (RoHS, REACH), and application suitability (ITE/commercial). Only devices with identical or narrower parameter envelopes, compliance status, and compatible mechanical form factors are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

TRA 1-1212 is marked "Not For New Designs," indicating end-of-life or obsolescence for new projects. Substitute parts must fully match regulatory compliance (ROHS3, REACH, ECCN, HTSUS) and meet all listed key electrical and mechanical parameters. IQ1212SA, from XP Power, meets these specific compliance standards. Only documented substitute relationships are to be used for new designs or ongoing support.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched for DC-DC converter substitution?
A1: Input voltage range, output voltage and current, total output power, isolation voltage, mounting method, package size, application rating, and applicable regulatory compliance.

Q2: Are there mechanical differences between TRA 1-1212 and IQ1212SA?
A2: TRA 1-1212 uses a 6-SIP module, 4 leads; IQ1212SA uses a 7-SIP module, 6 leads. Physical footprint dimensions are similar, but refer only to provided lead and package details for placement compatibility.

Q3: Is the operating temperature range identical between the substitutes?
A3: TRA 1-1212 supports -40°C ~ 95°C (with derating); IQ1212SA supports -40°C ~ 85°C. Compatibility is based strictly on these provided ranges.

Q4: Do substitutes meet the same compliance standards?
A4: Both TRA 1-1212 and IQ1212SA are ROHS3 compliant, have ECCN EAR99 classification, and are listed under HTSUS 8504.40.9580.

Q5: Can IQ1212SA be used in ITE (commercial) applications as a substitute?
A5: Both devices specify ITE (Commercial) application suitability as per provided data.

Q6: Is there any change in output performance when substituting IQ1212SA for TRA 1-1212?
A6: IQ1212SA has a maximum output current of 83mA; TRA 1-1212 provides 84mA. All other key output parameters and efficiency are within the specified values in the input data.
