ST-6-10 Equivalent & Substitute Parts

Part Overview

The ST-6-10 is a laminated core power transformer manufactured by Signal Transformer, rated at 20VA with dual secondary windings configured for parallel (5V, 4A) or series (10V, 2A) output. The primary winding accepts 115V single-phase input with 2500Vrms isolation. This through-hole mounted component is designed for PC pin termination and is ROHS3 compliant and REACH unaffected. As an active product with current inventory availability, substitute parts are identified to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST-6-10 is determined by strict equivalence across the following critical parameters:

• Power rating: 20VA
• Primary voltage: 115V single-phase input
• Secondary voltage configuration: Parallel 5V / Series 10V dual winding
• Secondary current capacity: Parallel 4A / Series 2A
• Core type: Laminated
• Winding configuration: Single primary, dual secondary, no center tap
• Mounting and termination: Through hole with PC pin termination
• Isolation voltage: 2500Vrms minimum
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The F10-2000 manufactured by Triad Magnetics meets all specified parameters and is classified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ST-6-10 and F10-2000 are active products with current manufacturer support and full regulatory compliance. Selection between these parts should be based on:

• Procurement availability and lead time requirements
• Packaging format preference (Bulk versus Box)
• Current inventory levels at authorized distributors
• Cost considerations within equivalent specifications
• Existing supply chain relationships with Signal Transformer or Triad Magnetics

Both parts satisfy ROHS3 compliance and REACH requirements for applications requiring environmental regulatory adherence. Physical dimensions are equivalent within manufacturing tolerances, confirming PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the F10-2000 be used as a direct replacement for the ST-6-10?

A: Yes. The F10-2000 meets all electrical and mechanical specifications of the ST-6-10, including power rating, voltage configuration, current capacity, core type, winding configuration, mounting type, termination style, and isolation voltage. Physical dimensions are equivalent within standard manufacturing tolerances.

Q: Are there differences in packaging between these parts?

A: The ST-6-10 is supplied in Bulk packaging, while the F10-2000 is supplied in Box packaging. This affects order quantities and storage considerations but does not impact electrical or mechanical performance.

Q: Do both parts support the same secondary voltage configurations?

A: Yes. Both the ST-6-10 and F10-2000 provide dual secondary windings configured for parallel 5V at 4A or series 10V at 2A operation.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the isolation voltage rating for both parts?

A: Both the ST-6-10 and F10-2000 provide 2500Vrms isolation between primary and secondary windings.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent within standard manufacturing tolerances. The ST-6-10 measures 57.20mm L x 47.60mm W x 36.90mm H (seated), while the F10-2000 measures 57.15mm L x 47.63mm W x 36.50mm H (seated). These variations are within acceptable PCB layout compatibility ranges for through-hole mounted components.
