F16-800 Equivalent & Substitute Parts Reference

Part Overview

The F16-800 is a laminated core power transformer manufactured by Triad Magnetics, rated at 12VA with dual secondary windings. This through-hole mounted component operates at 115V primary voltage with configurable secondary outputs of 8V parallel or 16V series. The part is currently active in production with 827 units in stock inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing from qualified manufacturers. The F16-800 maintains compatibility with substitute models that share identical electrical specifications and mechanical mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F16-800 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Primary voltage: 115V
• Secondary voltage configuration: Parallel 8V and Series 16V
• Maximum output current: Parallel 1.6A and Series 800mA
• Power rating: 12VA
• Isolation voltage: 2500Vrms
• Winding configuration: Single primary, dual secondary, no center tap

Mechanical Equivalence Requirements:

• Core type: Laminated
• Mounting type: Through hole
• Termination style: PC pin
• Regulatory compliance: ROHS3 or equivalent RoHS compliance

Identified Substitutes:

The F16-800 has two qualified equivalent parts that meet all electrical and mechanical criteria:

1. 164G16 (Hammond Manufacturing) - Laminated core, 12VA, identical voltage and current ratings, through-hole PC pin termination
2. 3FS-516 (Tamura) - Laminated core, 12VA, identical voltage and current ratings, through-hole PC pin termination

Both substitutes maintain full electrical compatibility and mechanical interchangeability with the F16-800.

Engineering Selection Recommendations

F16-800 (Triad Magnetics)

Primary selection when available. ROHS3 compliant. Smallest height profile at 36.50mm seated maximum. Compact footprint with dimensions 47.63mm L × 39.67mm W. Suitable for space-constrained applications. 827 units in current inventory.

164G16 (Hammond Manufacturing)

Direct electrical equivalent with identical dimensions (47.63mm L × 39.67mm W). ROHS3 compliant. Height of 38.10mm accommodates standard PCB layouts. 625 units available. Interchangeable with F16-800 in all electrical and mechanical aspects.

3FS-516 (Tamura)

Electrical equivalent with minor dimensional variations. Length 48.50mm and width 41.52mm represent 0.87mm and 1.85mm increases respectively. Height 38.00mm. RoHS compliant. 857 units in inventory. Suitable for applications where dimensional tolerance permits the specified variations.

All three parts share identical electrical specifications, isolation voltage, winding configuration, and regulatory compliance status. Selection between substitutes is determined by availability, dimensional constraints, and packaging requirements.

Frequently Asked Questions (FAQ)

Q: Can the 164G16 replace the F16-800 in existing designs?

A: Yes. The 164G16 maintains identical electrical specifications (12VA, 115V primary, 8V/16V secondary, 1.6A/800mA output) and mechanical mounting (through-hole PC pin). Dimensions are identical at 47.63mm L × 39.67mm W. Height difference of 1.60mm (38.10mm vs 36.50mm) is within standard PCB clearance tolerances.

Q: What are the dimensional differences between substitutes?

A: The F16-800 and 164G16 share identical footprints (47.63mm L × 39.67mm W). The 3FS-516 has a larger footprint at 48.50mm L × 41.52mm W, representing increases of 0.87mm and 1.85mm respectively. All three have similar heights within 1.60mm variation (36.50mm to 38.10mm).

Q: Are all substitutes RoHS compliant?

A: Yes. The F16-800 and 164G16 are ROHS3 compliant. The 3FS-516 is RoHS compliant. All three meet environmental regulatory requirements.

Q: What is the difference between packaging types listed?

A: The F16-800 is supplied in box packaging, the 164G16 in bulk packaging, and the 3FS-516 in tube packaging. Packaging type does not affect electrical or mechanical performance.

Q: Can the 3FS-516 be used if space is limited?

A: The 3FS-516 has a larger footprint (48.50mm L × 41.52mm W) compared to the F16-800 (47.63mm L × 39.67mm W). Use is restricted to applications where the dimensional increases of 0.87mm length and 1.85mm width are accommodated by PCB layout.

Q: Do all substitutes have identical isolation voltage?

A: Yes. All three parts (F16-800, 164G16, and 3FS-516) maintain 2500Vrms isolation voltage.

Q: What determines substitution eligibility?

A: Substitution is based on electrical equivalence (voltage, current, power rating, winding configuration) and mechanical compatibility (mounting type, termination style, core type). All identified substitutes meet these criteria.
