FS10-110 Equivalent & Substitute Parts Reference

Part Overview

The FS10-110 is a laminated core power transformer manufactured by Triad Magnetics, rated at 1.1VA with dual primary and dual secondary windings. This through-hole mounted component is designed for applications requiring isolated AC power conversion with selectable output configurations. The part is currently in active production status with 945 units in stock inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range. Alternative sources may be required due to supply chain considerations, lead time requirements, or packaging preferences.

Substitute Part Grouping Explanation

Substitution eligibility for the FS10-110 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Maximum power rating of 1.1VA
Primary voltage compatibility: 115V and 230V operation
Secondary voltage output: 5V (parallel) and 10V (series) configurations
Output current capacity: 220mA (parallel) and 110mA (series)
Isolation voltage rating: 2500Vrms minimum
Dual primary and dual secondary winding configuration

Mechanical Equivalence Requirements:

Laminated core construction
Through-hole mounting capability
PC pin termination style
Physical dimensions: 34.93mm L × 28.58mm W footprint

The Hammond Manufacturing 162D10 meets all electrical equivalence criteria and maintains mechanical compatibility through identical footprint dimensions and through-hole mounting. Secondary winding configuration differs (Single with Multiple Taps versus Dual), but functional output capability remains equivalent.

Engineering Selection Recommendations

FS10-110 (Triad Magnetics) Selection Criteria:

Primary application requirement with established supply chain
Space-constrained designs requiring minimum height (23.80mm seated)
Dual secondary winding configuration preferred for circuit topology
Active production status with 945 units in current inventory
ROHS3 compliance and REACH unaffected status confirmed

162D10 (Hammond Manufacturing) Selection Criteria:

Alternative sourcing requirement or extended lead time mitigation
Applications tolerating increased height profile (33.32mm seated)
Bulk packaging preference over box packaging
Equivalent electrical performance with multiple tap secondary configuration
Active production status with 910 units in current inventory
ROHS3 compliance and REACH unaffected status confirmed
MSL rating of 1 (Unlimited) for moisture-sensitive environments

Both parts maintain identical electrical specifications and footprint dimensions. Height differential (9.52mm) must be evaluated against PCB layout constraints. Secondary winding topology difference does not affect functional output capability for standard parallel/series configurations.

Frequently Asked Questions (FAQ)

Q: Can the 162D10 directly replace the FS10-110 in existing designs?

A: Electrical substitution is valid. The 162D10 provides identical voltage and current outputs. Physical height difference (33.32mm versus 23.80mm) requires verification against PCB clearance and enclosure constraints. Footprint dimensions (34.93mm × 28.58mm) are identical, confirming through-hole mounting compatibility.

Q: What is the functional difference between dual secondary windings and single secondary with multiple taps?

A: Both configurations deliver equivalent 5V parallel and 10V series output. The FS10-110 uses separate dual windings; the 162D10 uses a single winding with multiple tap points. Circuit performance and output specifications remain identical.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Isolation voltage (2500Vrms) is identical. The 162D10 specifies MSL 1 (Unlimited), while the FS10-110 lists MSL as Not Applicable. This difference does not affect electrical performance in standard applications.

Q: What packaging differences exist?

A: FS10-110 is supplied in box packaging; 162D10 is supplied in bulk packaging. Inventory levels are comparable (945 units versus 910 units). Packaging selection depends on procurement and storage requirements.

Q: Are both parts suitable for 115V and 230V primary operation?

A: Yes. Both the FS10-110 and 162D10 support dual primary voltage operation at 115V and 230V, with identical secondary output specifications for each configuration.

Q: What is the weight specification for both parts?

A: Both parts weigh 0.17 lb (77.11 g), confirming material and construction equivalence.
