F12-1600 Equivalent & Substitute Parts Reference

Part Overview

The F12-1600 is a laminated core power transformer manufactured by Triad Magnetics, rated at 20VA with a single primary winding and dual secondary windings. The transformer operates with 115V primary input and provides parallel 6.3V or series 12.6V secondary output configurations. This component is classified as Class 2/3 and is part of the Split Pack™ series. The F12-1600 maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Equivalent substitute parts are identified when electrical specifications, mechanical dimensions, mounting characteristics, and regulatory compliance align within acceptable engineering tolerances for through-hole laminated core transformer applications.

Parts meeting all electrical, mechanical, and regulatory criteria are classified as direct equivalents and substitutes.

Parameter Comparison

Engineering Selection Recommendations

The 164H12 manufactured by Hammond Manufacturing is a direct electrical and mechanical equivalent to the F12-1600. Both transformers satisfy identical electrical specifications across all primary and secondary voltage configurations, current ratings, and isolation requirements. Physical dimensions align within acceptable manufacturing tolerances, with seated height differing by 0.02mm (36.50mm versus 36.52mm), which does not impact through-hole PCB mounting compatibility.

Both parts maintain Active product status and carry identical regulatory certifications: RoHS3 compliance and REACH unaffected designation. Export classification (EAR99) and tariff codes (HTSUS 8504.31.4035) are identical, confirming regulatory equivalence.

The primary distinction between these parts is packaging and inventory availability. The F12-1600 is supplied in box packaging with 878 units in stock, while the 164H12 is supplied in bulk packaging with 1066 units in stock. The F12-1600 belongs to the Split Pack™ series, while the 164H12 belongs to the Hammond 164 series. Both are laminated core, Class 2/3 transformers suitable for identical circuit applications.

Selection between these equivalent parts should be based on packaging requirements, lead time, and inventory availability rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the 164H12 be used as a direct replacement for the F12-1600 in existing designs?

A: Yes. The 164H12 meets all electrical specifications, mechanical dimensions, mounting requirements, and regulatory certifications of the F12-1600. Through-hole PCB mounting compatibility is confirmed. No circuit redesign is required.

Q: Are there any dimensional differences that could affect PCB layout?

A: The seated height differs by 0.02mm (F12-1600: 36.50mm maximum; 164H12: 36.52mm maximum). This difference is within standard manufacturing tolerances and does not impact PCB clearance or mounting hole alignment for through-hole applications.

Q: Do both transformers provide the same voltage and current outputs?

A: Yes. Both the F12-1600 and 164H12 provide identical dual secondary winding configurations: parallel 6.3V at 3.2A or series 12.6V at 1.6A. Primary input is 115V for both units.

Q: What is the difference between box and bulk packaging?

A: Box packaging (F12-1600) provides individual unit packaging suitable for smaller orders or component kits. Bulk packaging (164H12) provides cost-effective packaging for larger volume orders. Electrical and mechanical specifications are identical regardless of packaging type.

Q: Are both transformers RoHS3 compliant?

A: Yes. Both the F12-1600 and 164H12 carry RoHS3 compliance certification and REACH unaffected status, confirming compliance with current environmental and hazardous substance regulations.

Q: What is the isolation voltage rating for these transformers?

A: Both transformers provide 2500Vrms isolation voltage between primary and secondary windings, meeting Class 2/3 safety requirements for power transformer applications.

Q: Can these transformers be used in series or parallel configurations?

A: The dual secondary windings support both series and parallel connection configurations. Series connection provides 12.6V at 1.6A output; parallel connection provides 6.3V at 3.2A output. Both configurations are supported identically on the F12-1600 and 164H12.
