Electrical Parameters:

• Identical primary voltage: 115V
• Identical secondary voltage configuration: Parallel 12V, Series 24V
• Identical output current ratings: Parallel 1.6A, Series 800mA
• Identical power rating: 20VA
• Identical isolation voltage: 2500Vrms
• Identical winding configuration: Single primary, dual secondary, no center tap

Mechanical Parameters:

• Identical mounting type: Through Hole
• Identical termination style: PC Pin
• Identical core type: Laminated
• Matching physical dimensions: 57.15mm L x 47.63mm W
• Height variation within acceptable tolerance: 36.50mm to 36.52mm
• Equivalent weight: 0.8 lb (362.87 g)

Compliance Parameters:

• ROHS3 Compliant status
• REACH Unaffected status
• Identical ECCN and HTSUS classifications

Parts meeting all electrical, mechanical, and compliance criteria are classified as direct equivalents and may be substituted without circuit redesign or application re-qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the F24-800 (Triad Magnetics) and 164H24 (Hammond Manufacturing) are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on the following engineering criteria:

F24-800 (Triad Magnetics):

• Primary choice for Split Pack™ series applications
• 879 units currently in stock
• Packaged in box format
• Moisture Sensitivity Level: Not Applicable

164H24 (Hammond Manufacturing):

• Alternative for Hammond Manufacturing series integration
• 737 units currently in stock
• Packaged in bulk format
• Moisture Sensitivity Level: 1 (Unlimited)

Both parts satisfy identical electrical specifications, mechanical dimensions, and regulatory compliance requirements. Selection may be determined by supply chain availability, packaging requirements, or existing manufacturer relationships. The 0.02mm height difference (36.50mm versus 36.52mm) is within standard PCB assembly tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 164H24 be directly substituted for the F24-800 in existing designs?

A: Yes. The 164H24 meets all electrical, mechanical, and compliance specifications of the F24-800. Identical primary voltage (115V), secondary voltage configuration (12V parallel / 24V series), output current ratings (1.6A parallel / 800mA series), power rating (20VA), isolation voltage (2500Vrms), mounting type (through hole), termination style (PC pin), and physical dimensions enable direct substitution without circuit modification.

Q: What is the difference in packaging between these parts?

A: The F24-800 is supplied in box packaging, while the 164H24 is supplied in bulk packaging. This distinction affects only logistics and storage considerations, not electrical or mechanical performance.

Q: Are there any height differences that affect PCB assembly?

A: The F24-800 has a maximum seated height of 36.50mm, while the 164H24 has a maximum seated height of 36.52mm. This 0.02mm difference is within standard PCB assembly tolerances and does not affect component placement or clearance in standard through-hole applications.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the F24-800 and 164H24 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference in Moisture Sensitivity Level between these parts?

A: The F24-800 has a Moisture Sensitivity Level designation of Not Applicable, while the 164H24 is rated MSL 1 (Unlimited). This difference reflects manufacturing process variations but does not affect functional performance or storage requirements for standard industrial applications.

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

A: Yes. Both the F24-800 and 164H24 feature dual secondary windings that support parallel configuration (12V at 1.6A) or series configuration (24V at 800mA). The winding configuration is identical between both parts.

Q: What is the isolation voltage rating, and why is it important?

A: Both parts provide 2500Vrms isolation voltage between primary and secondary windings. This rating ensures safe electrical isolation in Class 2/3 applications and protects against voltage transients and fault conditions.
