The substitute part 241-7-36 meets all specified electrical and mechanical parameters, enabling direct functional replacement in applications designed for the F7-36.

Parameter Comparison

Engineering Selection Recommendations

Both the F7-36 and 241-7-36 are active production parts with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between these parts should be based on:

Availability & Lead Time: Current inventory levels indicate 890 units of F7-36 and 810 units of 241-7-36 in stock. Either part supports immediate procurement without extended lead times.

Manufacturer Certification: Both manufacturers provide equivalent isolation voltage ratings (2500VAC/Vrms) and identical electrical performance specifications. Both parts carry identical ECCN (EAR99) and HTSUS (8504.31.4065) classifications.

Physical Compatibility: Dimensional variations between the two parts (maximum 3.18mm width difference, 0.65mm height difference) remain within acceptable tolerances for standard chassis mount applications. Both parts utilize compatible Solder and Quick Connect termination methods.

Supply Chain Continuity: The 241-7-36 (Signal Transformer Two-4-One™ series) serves as a direct functional equivalent, enabling procurement flexibility when F7-36 availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can the 241-7-36 be used as a direct replacement for the F7-36 in existing designs?

A: Yes. Both parts meet identical electrical specifications (115V primary, 36V secondary with center tap, 56VA, 1.5A maximum output) and share equivalent isolation voltage ratings (2500VAC/Vrms). Both are chassis mount configurations with compatible Solder and Quick Connect termination. Dimensional differences (3.18mm maximum width variance, 0.65mm maximum height variance) fall within standard chassis mount tolerances.

Q: Are there compliance differences between the F7-36 and 241-7-36?

A: No. Both parts carry identical RoHS3 compliance status and REACH unaffected designation. Both share the same ECCN (EAR99) and HTSUS (8504.31.4065) classifications, ensuring equivalent regulatory treatment in procurement and export scenarios.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in primary voltage (115V), secondary voltage (36V), output current rating (1.5A), power rating (56VA), core type (laminated), center tap presence, isolation voltage (2500VAC/Vrms minimum), mounting type (chassis mount), and termination compatibility (Solder and Quick Connect). Both parts meet all these criteria.

Q: Do the physical dimension differences affect installation?

A: The 241-7-36 measures 93.70mm L x 49.20mm W x 57.80mm H (max seated), compared to the F7-36 at 93.65mm L x 46.02mm W x 57.15mm H (max seated). These variations (0.05mm length, 3.18mm width, 0.65mm height) are within standard mechanical tolerances for chassis mount transformer applications and do not affect functional compatibility.

Q: What is the difference between the Triad Magnetics Quick Pack series and the Signal Transformer Two-4-One™ series?

A: These are manufacturer-specific product line designations. Both series deliver identical electrical performance and compliance specifications for this 56VA laminated core transformer category. Series designation does not affect substitution eligibility when all electrical and mechanical parameters are equivalent.

Q: Are both parts suitable for applications requiring 2500VAC isolation?

A: Yes. Both the F7-36 and 241-7-36 are rated for 2500VAC isolation voltage (expressed as 2500VAC for F7-36 and 2500Vrms for 241-7-36, representing equivalent specifications). Both parts meet this isolation requirement.
