FS36-030 Equivalent & Substitute Parts Reference

Part Overview

The FS36-030 is a laminated core power transformer manufactured by Triad Magnetics, rated at 1.1VA with dual primary and secondary windings. This through-hole mounted component operates at 115V or 230V primary voltage with configurable secondary output of 18V parallel or 36V series. The part maintains Active product status with full RoHS3 compliance and 2500Vrms isolation rating.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical power rating: 1.1VA
• Matching primary voltage configuration: 115V, 230V dual input
• Matching secondary voltage output: Parallel 18V, Series 36V
• Matching output current specifications: Parallel 60mA, Series 30mA
• Identical isolation voltage: 2500Vrms
• Identical winding configuration: Dual primary, dual secondary

Mechanical Equivalence Requirements:

• Through-hole mounting type
• PC pin termination style
• Compatible physical dimensions within tolerance
• Laminated core construction

Compliance Requirements:

• RoHS3 compliance maintained
• REACH unaffected status
• EAR99 classification

Two substitute parts meet these criteria:

DST-2-36 (Signal Transformer): Direct equivalent with identical electrical specifications and near-identical physical dimensions (34.90mm L x 28.60mm W vs. 34.93mm L x 28.56mm W). Height variance of 0.80mm (24.60mm vs. 23.80mm) remains within typical PCB assembly tolerances.

162D36 (Hammond Manufacturing): Similar equivalent with identical electrical specifications. Physical dimensions match primary and secondary lengths (34.93mm L x 28.58mm W). Height difference of 9.52mm (33.32mm vs. 23.80mm) represents a significant mechanical variance requiring board layout verification. Moisture sensitivity level differs (MSL 1 vs. Not Applicable), indicating different storage and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

DST-2-36 Selection Criteria: The DST-2-36 from Signal Transformer is the primary substitute option. All electrical parameters match exactly with the FS36-030. Physical dimensions are nearly identical with maximum height variance of 0.80mm, which falls within standard PCB assembly tolerances for through-hole components. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity classification. This part is suitable for direct substitution in existing designs without PCB layout modification.

162D36 Selection Criteria: The 162D36 from Hammond Manufacturing is a secondary substitute option. Electrical specifications are fully equivalent to the FS36-030. However, the seated height of 33.32mm exceeds the FS36-030 height of 23.80mm by 9.52mm. This significant dimensional difference requires verification of available vertical clearance on the PCB and potential interference with adjacent components or enclosure constraints. The MSL 1 rating indicates this part requires controlled storage conditions (unlimited shelf life at specified temperature/humidity), whereas the FS36-030 has no moisture sensitivity requirement. This part is suitable for substitution only when board layout permits the increased height profile.

Both substitute parts maintain Active product status and full compliance certifications equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can DST-2-36 be used as a direct replacement for FS36-030 without PCB modification?

A: Yes. The DST-2-36 provides direct electrical equivalence with all primary and secondary voltage, current, and isolation specifications matching the FS36-030. The height difference of 0.80mm is within standard through-hole component tolerances and does not require PCB layout changes.

Q: What is the primary limitation of using 162D36 as a substitute?

A: The 162D36 has a seated height of 33.32mm compared to the FS36-030 at 23.80mm, a difference of 9.52mm. This requires verification that the PCB assembly has sufficient vertical clearance and that no component interference occurs. Additionally, the MSL 1 rating requires controlled storage conditions during inventory management.

Q: Are all three parts electrically interchangeable?

A: Yes. The FS36-030, DST-2-36, and 162D36 are electrically interchangeable. All three provide identical power rating (1.1VA), primary voltage configuration (115V, 230V), secondary voltage output (Parallel 18V, Series 36V), output current specifications (Parallel 60mA, Series 30mA), and isolation voltage (2500Vrms).

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and classified as EAR99. The primary compliance difference is the moisture sensitivity level: FS36-030 and DST-2-36 have no moisture sensitivity requirement, while 162D36 is rated MSL 1 (unlimited shelf life).

Q: What packaging differences exist between these parts?

A: FS36-030 and DST-2-36 are supplied in box packaging. The 162D36 is supplied in bulk packaging. This affects inventory management and component handling procedures but does not impact electrical or mechanical performance.

Q: Which substitute part has the highest inventory availability?

A: DST-2-36 has 995 pieces in stock, compared to 806 pieces for FS36-030 and 964 pieces for 162D36. Inventory levels are subject to change and should be verified at time of procurement.

Q: Can the 162D36 be used in space-constrained applications?

A: The 162D36 is not recommended for space-constrained applications due to its 33.32mm height. The FS36-030 and DST-2-36, both at approximately 24mm height, are better suited for applications with limited vertical clearance.
