F12-090 Equivalent & Substitute Parts Reference

Part Overview

The F12-090 is a laminated core power transformer manufactured by Triad Magnetics, rated at 1.1VA with dual secondary windings. This through-hole mounted component operates at 115V primary voltage with configurable secondary outputs of 6.3V parallel or 12.6V 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, procurement lead times extend, or design flexibility permits alternative manufacturers while maintaining electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F12-090 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical primary voltage: 115V
• Identical secondary voltage outputs: 6.3V parallel and 12.6V series
• Identical maximum output current: 180mA parallel, 90mA series
• Identical power rating: 1.1VA
• Identical isolation voltage: 2500Vrms
• Identical winding configuration: Single primary, dual secondary, no center tap

Mechanical Equivalence Requirements:

• Identical mounting type: Through Hole
• Identical termination style: PC Pin
• Compatible physical dimensions within manufacturing tolerances
• Identical core type: Laminated

Compliance Requirements:

• RoHS3 compliance or equivalent RoHS compliance
• REACH Unaffected or REACH Compliant status
• Identical ECCN and HTSUS classifications

Parts 164D12 (Hammond Manufacturing) and 3FS-212 (Tamura) meet all electrical and mechanical equivalence criteria and are classified as direct substitutes for the F12-090.

Parameter Comparison

Engineering Selection Recommendations

F12-090 (Triad Magnetics - Primary Part)

The F12-090 maintains Active product status with full RoHS3 compliance. Current inventory of 894 pieces supports immediate procurement. This part is suitable for applications where Triad Magnetics supply chain and specifications are established.

164D12 (Hammond Manufacturing - Direct Substitute)

The 164D12 provides electrical equivalence with identical power, voltage, and current specifications. Physical dimensions are nearly identical to the F12-090 (length and width within 0.02mm). The seated height of 33.32mm exceeds the F12-090 by 9.52mm; this dimension must be evaluated against available PCB clearance in the target application. RoHS3 compliance and Active product status confirm regulatory alignment. Inventory of 726 pieces supports procurement. Packaging format is Bulk rather than Box.

3FS-212 (Tamura - Direct Substitute)

The 3FS-212 delivers complete electrical equivalence across all voltage, current, and power parameters. Physical dimensions show minor variations: length increases by 0.63mm, width by 2.42mm, and seated height by 1.60mm relative to the F12-090. These dimensional differences remain within typical PCB layout tolerances for through-hole components. RoHS compliance and Active product status are confirmed. Inventory of 2370 pieces provides the highest availability among all three options. Packaging format is Tube.

All three parts share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the 164D12 be used as a direct replacement for the F12-090 in existing designs?

A: The 164D12 is electrically equivalent and mechanically compatible for through-hole mounting. The primary consideration is the seated height difference of 9.52mm (164D12 at 33.32mm versus F12-090 at 23.80mm). PCB layout must accommodate this increased height. If vertical clearance is available, the 164D12 functions as a direct substitute.

Q: What is the significance of the dimensional differences between the 3FS-212 and F12-090?

A: The 3FS-212 dimensions vary by less than 1mm in length and width, and 1.60mm in seated height. These variations are within standard manufacturing tolerances for laminated core transformers and do not affect electrical performance. PCB footprint and clearance requirements should be verified for the specific application.

Q: Are all three parts RoHS compliant?

A: Yes. The F12-090 and 164D12 are ROHS3 Compliant. The 3FS-212 is RoHS Compliant. All three parts meet current RoHS regulatory requirements and are suitable for applications requiring RoHS certification.

Q: What packaging formats are available for each part?

A: F12-090 is supplied in Box packaging. 164D12 is supplied in Bulk packaging. 3FS-212 is supplied in Tube packaging. Packaging selection may influence procurement quantity requirements and handling procedures.

Q: Do all three parts have identical electrical specifications?

A: Yes. All three parts share identical primary voltage (115V), secondary voltages (6.3V parallel, 12.6V series), output currents (180mA parallel, 90mA series), power rating (1.1VA), isolation voltage (2500Vrms), and winding configuration (single primary, dual secondary, no center tap).

Q: Which part has the highest current inventory availability?

A: The 3FS-212 (Tamura) has the highest inventory at 2370 pieces, followed by the F12-090 at 894 pieces, and the 164D12 at 726 pieces.

Q: Are there any compliance or export restrictions that differ between these parts?

A: No. All three parts share identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications. REACH status is either Unaffected or Compliant across all three parts, confirming equivalent regulatory treatment for export and tariff purposes.
