Key Parameters

Substitute Part Grouping Explanation

The FP10-1200 manufactured by Triad Magnetics qualifies as a direct substitute for the LP-10-1200 based on the following matching parameters:

• Power rating: 12VA
• Primary voltage options: 115V, 230V
• Secondary voltage configuration: Parallel 5V / Series 10V
• Output current capacity: Parallel 2.4A / Series 1.2A
• Primary and secondary winding configuration: Dual / Dual
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 64.60mm L x 50.80mm W
• Weight: 0.688 lb (312.07 g)
• Regulatory compliance: ROHS3 Compliant

The primary difference is the core construction: the LP-10-1200 uses semi-toroidal core technology, while the FP10-1200 uses laminated core technology. Both designs meet the specified electrical and mechanical requirements for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the LP-10-1200 and FP10-1200 are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Core construction preference: Semi-toroidal (LP-10-1200) versus laminated (FP10-1200)
• Isolation voltage requirement: The FP10-1200 provides 2000Vrms isolation compared to 1500Vrms for the LP-10-1200
• Height constraint: The FP10-1200 seated height is 26.97mm versus 27.10mm for the LP-10-1200
• Packaging format: LP-10-1200 supplied in bulk; FP10-1200 supplied in box

Both parts meet the specified electrical and mechanical parameters and are suitable for direct substitution in applications requiring 12VA dual-winding power transformation with configurable output voltage and current.

Frequently Asked Questions (FAQ)

Q: Can the FP10-1200 replace the LP-10-1200 in existing designs?

A: Yes. Both parts share identical electrical specifications including power rating, voltage options, current capacity, and winding configuration. Physical dimensions are equivalent within tolerance. The primary difference is core construction technology.

Q: What is the difference between semi-toroidal and laminated core construction?

A: Semi-toroidal and laminated cores are different magnetic core geometries. The choice between them depends on application-specific requirements such as EMI performance, thermal characteristics, and mechanical constraints. Both designs in this comparison meet the specified 12VA power rating and isolation voltage requirements.

Q: Does the higher isolation voltage of the FP10-1200 affect compatibility?

A: No. The FP10-1200 provides 2000Vrms isolation versus 1500Vrms for the LP-10-1200. Higher isolation voltage is a superset capability and does not create incompatibility. Applications requiring 1500Vrms isolation will operate correctly with the FP10-1200.

Q: Are there packaging considerations for substitution?

A: Yes. The LP-10-1200 is supplied in bulk packaging, while the FP10-1200 is supplied in box packaging. Procurement and inventory management processes may need adjustment based on packaging format preference.

Q: Do both parts meet regulatory requirements?

A: Yes. Both the LP-10-1200 and FP10-1200 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and the same HTSUS code (8504.31.4035).
