Engineering Selection Recommendations

The Triad Magnetics F24-800 is a direct functional equivalent to the obsolete TE Connectivity 4900-8024RE64. Selection of the F24-800 is supported by the following factors:

Electrical Compatibility: Both transformers deliver identical primary and secondary voltage specifications with compatible output current ratings. The F24-800 parallel mode current rating of 1.6A and series mode rating of 800mA remain within acceptable tolerance of the original 1.666A and 833mA specifications.

Mechanical Compatibility: Physical dimensions are within acceptable manufacturing tolerances. The F24-800 height of 36.50mm represents a 0.7mm increase over the original 35.80mm specification, which remains compatible with standard through-hole PCB layouts.

Compliance Status: The F24-800 carries ROHS3 compliance certification, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications.

Product Availability: The F24-800 maintains active product status with current inventory availability, ensuring supply chain continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the Triad Magnetics F24-800 be used as a direct replacement for the TE Connectivity 4900-8024RE64?

A: Yes. The F24-800 meets all electrical and mechanical specifications for direct substitution. Both transformers provide identical primary voltage (115V), secondary voltage configurations (parallel 12V, series 24V), power rating (20VA), core type (laminated), mounting method (through-hole), and termination style (PC pin).

Q: Are there any dimensional differences between these transformers?

A: Dimensional differences are minimal and within acceptable manufacturing tolerances. The F24-800 is 0.15mm longer, 0.03mm wider, and 0.7mm taller than the original part. These variations do not affect standard PCB layout compatibility.

Q: What is the significance of the product status difference?

A: The TE Connectivity 4900-8024RE64 is classified as obsolete, indicating discontinued manufacturing and limited availability. The Triad Magnetics F24-800 maintains active product status with current production and inventory support, making it the appropriate choice for new designs and ongoing system maintenance.

Q: Do both transformers meet current RoHS requirements?

A: Yes. The original part carries RoHS compliance certification. The F24-800 carries ROHS3 compliance, which represents the current regulatory standard. Both parts are compliant with applicable environmental regulations.

Q: Are the output current ratings identical between these transformers?

A: Output current ratings are compatible but not identical. The F24-800 provides 1.6A in parallel mode (versus 1.666A original) and 800mA in series mode (versus 833mA original). These minor differences remain within acceptable operating parameters for equivalent functionality.

Q: What packaging format is used for the F24-800?

A: The F24-800 is supplied in box packaging, compared to the original part's standard packaging. This does not affect component functionality or PCB integration.
