Part Overview

The FS16-070 is a laminated core power transformer manufactured by Triad Magnetics with a maximum power rating of 1.1VA. This through-hole mounted component features dual primary and secondary windings, supporting both 115V and 230V primary inputs with configurable secondary outputs of 8V (parallel) or 16V (series). The transformer is designed for PC pin termination and maintains 2500Vrms isolation voltage. As an active product with ROHS3 compliance and REACH unaffected status, the FS16-070 remains in production. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring laminated core power transformation at this specification level.

Substitute Part Grouping Explanation

Substitute parts for the FS16-070 are classified based on electrical and mechanical parameter alignment. All identified substitutes maintain identical electrical specifications: 1.1VA maximum power, dual primary windings supporting 115V/230V inputs, dual secondary windings with parallel 8V/series 16V outputs, 140mA parallel/70mA series maximum output current, laminated core construction, through-hole mounting, PC pin termination, and 2500Vrms isolation voltage.

Substitution eligibility is determined by the following critical parameters:

• Power rating: 1.1VA (exact match required)
• Primary voltage configuration: 115V, 230V dual input (exact match required)
• Secondary voltage outputs: Parallel 8V, Series 16V (exact match required)
• Maximum output current: Parallel 140mA, Series 70mA (exact match required)
• Core type: Laminated (exact match required)
• Winding configuration: Dual primary, dual secondary (exact match required)
• Mounting and termination: Through hole, PC pin (exact match required)
• Isolation voltage: 2500Vrms (exact match required)

Mechanical dimensions and packaging format may vary within acceptable tolerances for through-hole applications. All substitute parts listed maintain active product status and compliance certifications suitable for direct component selection.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—FS16-070, 3FD-216, DST-2-16, and 162D16—are active products with full electrical parameter equivalence. Selection between these components should be based on the following engineering criteria:

Direct Equivalents (Preferred for Direct Substitution):

The DST-2-16 (Signal Transformer) and 162D16 (Hammond Manufacturing) are direct equivalents to the FS16-070. Both maintain identical electrical specifications and near-identical physical dimensions. The DST-2-16 has a seated height of 24.60mm compared to the FS16-070's 23.80mm, representing a 0.80mm variance. The 162D16 has a seated height of 33.32mm, representing a 9.52mm variance. Both parts carry ROHS3 compliance matching the FS16-070.

The 3FD-216 (Tamura) is electrically equivalent but has increased physical dimensions: 35.56mm length (0.63mm larger), 31.00mm width (2.44mm larger), and 38.00mm seated height (14.20mm larger). This part carries RoHS compliance without the ROHS3 designation. The 3FD-216 is suitable for applications where physical space constraints are not limiting factors.

Compliance Considerations:

The FS16-070, DST-2-16, and 162D16 all carry ROHS3 compliance certification. The 3FD-216 carries RoHS compliance. For applications requiring ROHS3 certification, the DST-2-16 or 162D16 are preferred selections. All parts are EAR99 classified and REACH unaffected.

Packaging and Inventory:

The FS16-070 is supplied in box packaging with 1033 pieces in stock. The 3FD-216 is supplied in tube packaging with 5404 pieces in stock. The DST-2-16 is supplied in box packaging with 3466 pieces in stock. The 162D16 is supplied in bulk packaging with 797 pieces in stock. Packaging format selection depends on assembly process requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: Can the 3FD-216 be used as a direct replacement for the FS16-070 in a space-constrained PCB layout?

A: The 3FD-216 has identical electrical specifications but larger physical dimensions (35.56mm L x 31.00mm W x 38.00mm H seated) compared to the FS16-070 (34.93mm L x 28.56mm W x 23.80mm H seated). The 3FD-216 is not suitable for applications with strict height or footprint constraints. The DST-2-16 or 162D16 are preferred for space-limited designs.

Q: What is the difference between ROHS3 and RoHS compliance on these transformers?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive 3 (2015/863/EU), which includes restrictions on phthalates in addition to the six substances restricted under RoHS 2. The FS16-070, DST-2-16, and 162D16 carry ROHS3 certification. The 3FD-216 carries RoHS compliance. For applications requiring ROHS3 certification, select from the FS16-070, DST-2-16, or 162D16.

Q: Are all substitute parts rated for the same isolation voltage?

A: Yes. All four parts—FS16-070, 3FD-216, DST-2-16, and 162D16—are rated for 2500Vrms isolation voltage. Isolation voltage is identical across all equivalent and substitute parts.

Q: What are the electrical output configurations available on these transformers?

A: All four parts feature dual secondary windings that can be configured for parallel or series operation. In parallel configuration, the secondary output is 8V at 140mA maximum. In series configuration, the secondary output is 16V at 70mA maximum. Primary input supports both 115V and 230V operation through dual primary windings.

Q: Which substitute part has the smallest physical footprint?

A: The FS16-070 has the smallest seated height at 23.80mm. The DST-2-16 is the closest substitute with a seated height of 24.60mm (0.80mm taller). For applications requiring minimal height, the FS16-070 or DST-2-16 are recommended. The 162D16 has a seated height of 33.32mm, and the 3FD-216 has a seated height of 38.00mm.

Q: Can these transformers be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all four parts. Mechanical interchangeability depends on PCB layout constraints. The FS16-070, DST-2-16, and 162D16 have nearly identical footprints (34.90–34.93mm length, 28.56–28.58mm width) and are mechanically interchangeable for most through-hole applications. The 3FD-216 has a larger footprint and may require PCB layout modifications. Verify mounting hole spacing and height clearance before substitution.

Q: What packaging formats are available for these parts?

A: The FS16-070 is supplied in box packaging. The 3FD-216 is supplied in tube packaging. The DST-2-16 is supplied in box packaging. The 162D16 is supplied in bulk packaging. Packaging selection should align with assembly process requirements and component handling protocols.

Q: Are all parts currently in active production?

A: Yes. All four parts—FS16-070, 3FD-216, DST-2-16, and 162D16—maintain active product status with manufacturers. Current inventory levels are: FS16-070 (1033 pcs), 3FD-216 (5404 pcs), DST-2-16 (3466 pcs), and 162D16 (797 pcs).
