F120-010 Equivalent & Substitute Parts Reference

Part Overview

The F120-010 is a laminated core power transformer manufactured by Triad Magnetics, rated at 1.1VA with dual secondary windings. This through-hole mounted component operates at 115V primary voltage with configurable secondary outputs (60V parallel or 120V series) and delivers maximum output currents of 20mA (parallel) or 10mA (series). The part is actively produced and maintains ROHS3 compliance with 2500Vrms isolation rating. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

The F120-010 substitute relationship is established with the Hammond Manufacturing 164D120 based on strict electrical and mechanical equivalence. Substitution criteria are limited to the following parameters:

• Identical power rating (1.1VA)
• Identical primary voltage (115V)
• Identical secondary voltage outputs (60V parallel, 120V series)
• Identical maximum output currents (20mA parallel, 10mA series)
• Identical winding configuration (single primary, dual secondary, no center tap)
• Identical core type (laminated)
• Identical mounting type (through hole)
• Identical termination style (PC pin)
• Identical isolation voltage (2500Vrms)
• Identical regulatory compliance (ROHS3, REACH Unaffected, EAR99)

Physical dimensions show minor variation in height (23.80mm vs. 33.32mm seated height), which does not affect electrical substitution but must be verified for mechanical fit in the target application.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 164D120 is electrically and functionally equivalent to the F120-010 across all specified parameters. Both components maintain active product status and satisfy identical regulatory requirements (ROHS3, REACH Unaffected, EAR99 classification).

Selection between these parts should be based on:

1. Mechanical Fit: The 164D120 has a maximum seated height of 33.32mm compared to 23.80mm for the F120-010. Verify clearance in the target PCB assembly before substitution.

2. Availability: The 164D120 maintains higher inventory (1160 pcs) compared to F120-010 (748 pcs), which may influence lead time considerations.

3. Packaging: F120-010 is supplied in box packaging; 164D120 is supplied in bulk packaging. Confirm packaging requirements for procurement and handling.

4. Compliance Verification: Both parts carry identical isolation voltage (2500Vrms) and regulatory certifications, confirming suitability for equivalent safety-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 164D120 directly replace the Triad F120-010 in all applications?

A: Electrical substitution is valid when all specified parameters match. The 164D120 meets all electrical and regulatory requirements. However, the 9.52mm difference in seated height (33.32mm vs. 23.80mm) requires mechanical verification in the target assembly to confirm PCB clearance and mounting compatibility.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid only when the following parameters are identical: power rating (1.1VA), primary voltage (115V), secondary voltages (60V parallel, 120V series), output currents (20mA parallel, 10mA series), winding configuration (single primary, dual secondary), core type (laminated), mounting type (through hole), termination style (PC pin), and isolation voltage (2500Vrms).

Q: Are there compliance differences between these parts?

A: No. Both the F120-010 and 164D120 carry identical regulatory status: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Both are suitable for equivalent safety and environmental compliance requirements.

Q: Does the packaging difference affect electrical performance?

A: No. Packaging (box vs. bulk) does not affect electrical performance or component specifications. Packaging selection is a procurement and logistics consideration only.

Q: What should be verified before implementing the 164D120 as a substitute?

A: Verify mechanical fit by confirming that the 33.32mm maximum seated height of the 164D120 does not exceed available clearance in the target PCB assembly. Confirm that PC pin termination and through-hole mounting are compatible with the existing circuit board design.
