F36-170 Equivalent & Substitute Parts Reference

Part Overview

The F36-170 is a laminated core power transformer manufactured by Triad Magnetics, rated at 6VA with dual secondary windings. This through-hole mounted component operates at 115V primary voltage with configurable secondary outputs of 18V parallel or 36V series. The part is currently active in production and ROHS3 compliant, making it suitable for Class 2/3 applications requiring isolated AC power conversion in compact form factors.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the F36-170 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Identical primary voltage: 115V
Identical secondary voltage configuration: Parallel 18V / Series 36V
Identical output current ratings: Parallel 340mA / Series 170mA
Identical power rating: 6VA
Identical isolation voltage: 2500Vrms
Identical winding configuration: Single primary, dual secondary, no center tap

Mechanical Equivalence Requirements:

Identical core type: Laminated
Identical mounting type: Through Hole
Identical termination style: PC Pin
Identical physical dimensions: 41.28mm L x 33.32mm W x 33.32mm H (seated)

Compliance Requirements:

ROHS3 compliance maintained
REACH unaffected status maintained
Identical ECCN and HTSUS classifications

The substitute part 164F36 meets all electrical, mechanical, and compliance criteria for direct substitution in applications requiring the F36-170.

Engineering Selection Recommendations

Both the F36-170 and 164F36 are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following factors:

Availability and Lead Time: The 164F36 (Hammond Manufacturing) currently has 822 units in stock compared to 680 units for the F36-170 (Triad Magnetics). For applications with immediate procurement requirements, inventory availability may determine part selection.

Packaging Considerations: The F36-170 is supplied in box packaging, while the 164F36 is supplied in bulk packaging. Packaging selection depends on assembly process requirements and inventory management protocols.

Series Designation: The F36-170 belongs to the Split Pack™ series (Class 2/3, F series), while the 164F36 belongs to the Hammond 164 series. Both series designations indicate active production status with established supply chains.

Regulatory Compliance: Both parts maintain identical compliance certifications (ROHS3, REACH unaffected, EAR99 ECCN, 8504.31.4035 HTSUS). No compliance advantage exists between the two options.

For applications where the F36-170 is specified, the 164F36 provides full electrical and mechanical equivalence with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can the 164F36 be used as a direct replacement for the F36-170 in existing designs?

A: Yes. The 164F36 meets all electrical specifications (6VA, 115V primary, 18V/36V secondary, 340mA/170mA output, 2500Vrms isolation), mechanical specifications (laminated core, through-hole mounting, PC pin termination, identical dimensions), and compliance requirements (ROHS3, REACH unaffected) of the F36-170. No circuit modifications are required.

Q: Are there any differences in performance between the F36-170 and 164F36?

A: No performance differences exist. Both transformers are rated identically across all electrical parameters including power rating, voltage outputs, current capacity, and isolation voltage.

Q: What is the difference between the packaging options?

A: The F36-170 is supplied in box packaging, suitable for smaller quantity orders and individual component handling. The 164F36 is supplied in bulk packaging, typically used for higher-volume production runs. Packaging selection does not affect component performance or compatibility.

Q: Are both parts currently in production?

A: Yes. Both the F36-170 (Triad Magnetics) and 164F36 (Hammond Manufacturing) are active production components with established inventory levels.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control purposes, and share the identical HTSUS tariff classification (8504.31.4035).

Q: What determines whether a transformer can substitute for the F36-170?

A: Substitution requires equivalence across three categories: electrical parameters (power rating, voltage, current, isolation), mechanical specifications (core type, mounting, termination, dimensions), and compliance certifications (ROHS, REACH, export classifications). The 164F36 meets all three criteria.
