Substitute Part Grouping Explanation

Substitution of the 6053-120 is based on electrical and mechanical compatibility parameters that ensure functional equivalence in circuit applications. The critical parameters determining substitution eligibility are:

• Power Rating: 12VA maximum power handling
• Primary Voltage Capability: Dual selection between 115V and 230V input
• Secondary Voltage Configuration: Parallel 60V and Series 120V outputs
• Output Current Ratings: Parallel 200mA and Series 100mA maximum
• Core Architecture: Laminated core construction
• Winding Configuration: Dual primary and dual secondary windings
• Isolation Voltage: 1500Vrms dielectric strength
• Mounting and Termination: Through-hole package with PC pin termination
• Form Factor: Physical dimensions within 34.93mm L × 28.58mm W footprint and 30.15mm seated height

The substitute part 6053R-120 maintains electrical equivalence across all specified parameters while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 6053-120 is obsolete and no longer in active production. The 6053R-120 provides complete electrical and mechanical compatibility as a direct substitute, with identical power rating, voltage configurations, current specifications, and physical form factor.

The primary differentiation between these parts is regulatory compliance status. The 6053R-120 achieves ROHS3 compliance, whereas the 6053-120 is RoHS non-compliant. Both parts maintain equivalent REACH and ECCN classifications. For applications with regulatory requirements or procurement policies specifying RoHS compliance, the 6053R-120 is the appropriate selection. For applications without such restrictions, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the 6053-120 and 6053R-120 electrically identical? A: Yes. Both parts share identical power rating (12VA), primary voltage options (115V/230V), secondary voltage configurations (parallel 60V, series 120V), maximum output currents (parallel 200mA, series 100mA), isolation voltage (1500Vrms), and winding configurations (dual primary and secondary).

Q: Will the 6053R-120 fit in a circuit board designed for the 6053-120? A: Yes. Both parts are through-hole mounted with identical physical dimensions (34.93mm L × 28.58mm W), seated height (30.15mm maximum), and PC pin termination. They share the same footprint and mounting requirements.

Q: What is the difference between these two part numbers? A: The 6053R-120 is the active production equivalent of the obsolete 6053-120. The substitute offers improved compliance status (ROHS3 compliant versus RoHS non-compliant). All electrical specifications and physical characteristics remain unchanged.

Q: Can I use the 6053-120 in a new design? A: The 6053-120 is classified as obsolete and is not recommended for new designs. The 6053R-120 should be used for all new applications requiring this transformer specification.

Q: What compliance certifications apply to these transformers? A: Both parts are classified as ECCN EAR99 and REACH Unaffected. The 6053R-120 additionally achieves ROHS3 compliance, providing enhanced regulatory alignment with modern procurement standards.
