FP10-1200 Equivalent & Substitute Parts

Part Overview

The FP10-1200 is a 12VA laminated core power transformer manufactured by Triad Magnetics, designed for through-hole mounting applications. This transformer features dual primary and secondary windings with selectable output configurations (parallel 5V at 2.4A or series 10V at 1.2A) and dual input voltage options (115V or 230V). The product maintains Active status with 887 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to component availability, packaging preferences, or design revision requirements.

Substitute Part Grouping Explanation

Substitute parts for the FP10-1200 are classified into two categories based on substitution criteria:

Direct Manufacturer Substitute (FP10-1200-B): This part maintains identical electrical specifications and mechanical dimensions as the main part. The only difference is packaging format (Bulk versus Box). This substitute is applicable when packaging requirements differ while maintaining all functional and compliance parameters.

Similar Manufacturer Substitute (229B10): This Hammond Manufacturing transformer provides electrical equivalence across all critical parameters: 12VA power rating, dual primary/secondary windings, 115V/230V input options, and identical output configurations (parallel 5V at 2.4A, series 10V at 1.2A). The core type differs (semi-toroidal versus laminated), resulting in minor dimensional variations and a reduced isolation voltage specification (1750Vrms versus 2000Vrms). This substitute is applicable when electrical performance equivalence is the primary requirement and core type flexibility is acceptable.

Key Parameters Determining Substitution:

• Power rating (12VA)
• Primary voltage options (115V, 230V)
• Secondary voltage outputs (parallel 5V, series 10V)
• Output current ratings (parallel 2.4A, series 1.2A)
• Winding configuration (dual primary, dual secondary)
• Mounting type (through hole)
• Termination style (PC pin)

Parameter Comparison

Engineering Selection Recommendations

FP10-1200-B Selection Criteria: Select this direct substitute when packaging format must change from Box to Bulk while maintaining identical electrical performance and mechanical specifications. Both parts carry Active product status and ROHS3 compliance. Inventory availability is 684 units for FP10-1200-B versus 887 units for the main part.

229B10 Selection Criteria: Select this Hammond Manufacturing substitute when core type flexibility is acceptable and electrical equivalence is the primary design requirement. The 229B10 maintains all critical electrical parameters and meets ROHS3 and REACH compliance standards. The reduced isolation voltage (1750Vrms versus 2000Vrms) must be evaluated against application requirements. Dimensional differences include transposed length and width (50.80mm x 63.50mm versus 63.50mm x 50.80mm) and a marginal height increase (27.18mm versus 26.97mm). Weight reduction of approximately 0.058 lb occurs with the semi-toroidal design. Inventory availability is 873 units.

Compliance Verification: All substitute parts maintain Active product status, ROHS3 compliance, and REACH Unaffected designation, ensuring regulatory equivalence with the main part.

Frequently Asked Questions (FAQ)

Q: Can FP10-1200-B be used as a direct replacement for FP10-1200 in production assemblies?

A: Yes. FP10-1200-B provides complete electrical and mechanical equivalence. The only difference is packaging format (Bulk versus Box). All electrical specifications, dimensions, isolation voltage, and compliance certifications are identical.

Q: What are the key differences between FP10-1200 and 229B10?

A: The primary differences are: (1) Core type—FP10-1200 uses laminated core while 229B10 uses semi-toroidal core; (2) Isolation voltage—FP10-1200 provides 2000Vrms while 229B10 provides 1750Vrms; (3) Dimensions—FP10-1200 is 63.50mm L x 50.80mm W while 229B10 is 50.80mm L x 63.50mm W; (4) Weight—FP10-1200 weighs 0.688 lb while 229B10 weighs 0.63 lb. All electrical output specifications are identical.

Q: Is the 229B10 suitable for applications requiring 2000Vrms isolation?

A: No. The 229B10 provides 1750Vrms isolation, which is 250Vrms lower than the FP10-1200. Applications with isolation voltage requirements of 2000Vrms must use FP10-1200 or FP10-1200-B.

Q: Are dimensional differences between FP10-1200 and 229B10 significant for PCB layout?

A: Yes. The length and width dimensions are transposed (63.50mm x 50.80mm versus 50.80mm x 63.50mm), and height differs by 0.21mm. PCB footprint and mounting hole patterns must be verified before substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. FP10-1200, FP10-1200-B, and 229B10 all carry ROHS3 compliance and REACH Unaffected designation. All parts are classified as EAR99 for export control purposes.

Q: Which substitute should be selected for cost optimization?

A: Selection should be based on electrical and mechanical requirements, not cost alone. FP10-1200-B is electrically and mechanically identical to FP10-1200 and differs only in packaging. The 229B10 offers weight reduction and different core technology but requires verification of isolation voltage and dimensional compatibility.

Q: What is the inventory status for each part?

A: FP10-1200 has 887 units in stock, FP10-1200-B has 684 units, and 229B10 has 873 units. All parts maintain Active product status with current availability.
