6022-020 Equivalent & Substitute Parts

Part Overview

The 6022-020 is a laminated core power transformer manufactured by API Delevan Inc., rated for 1.1VA with dual primary and secondary windings. This transformer supports input voltages of 115V or 230V and delivers output configurations of 10V parallel or 20V series with maximum output currents of 110mA parallel or 55mA series respectively. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and repair operations.

Substitute Part Grouping Explanation

Substitution compatibility for the 6022-020 is determined by electrical and mechanical parameter equivalence across five critical dimensions:

Power Rating: Substitute parts must deliver the same 1.1VA capacity to ensure proper operation in circuits designed for this power envelope.
Voltage Specifications: Both primary voltage selection (115V/230V) and secondary voltage configurations (10V parallel, 20V series) must be identical to maintain circuit compatibility.
Output Current Capability: Maximum output currents of 110mA (parallel) and 55mA (series) define the load capacity for which the transformer is rated.
Physical Footprint and Mounting: The 34.93mm × 28.58mm × 23.80mm dimensions and through-hole PC pin termination must match to ensure PCB compatibility without redesign.
Electrical Isolation: The 2500Vrms isolation rating provides safety margin requirements that must be maintained in substitute parts.

The 6022R-020 meets all these criteria, providing a direct functional and mechanical substitute for the obsolete 6022-020.

Engineering Selection Recommendations

The 6022R-020 represents the optimal substitute for the obsolete 6022-020. Both parts share identical electrical specifications and physical dimensions, ensuring direct compatibility without circuit or PCB modifications. The primary distinction is product lifecycle status: the 6022-020 is obsolete with no ongoing production, while the 6022R-020 remains active with confirmed inventory availability (1148 units).

For compliance-sensitive applications, the 6022R-020 offers additional value through ROHS3 compliance, whereas the 6022-020 is RoHS non-compliant. Both parts maintain REACH unaffected status and carry the same EAR99 ECCN classification. The selection of 6022R-020 ensures long-term supply chain reliability and regulatory compliance for new designs and system upgrades.

Frequently Asked Questions (FAQ)

Q: What makes the 6022R-020 a direct substitute for the 6022-020?

A: The 6022R-020 shares identical electrical parameters (1.1VA power rating, 115V/230V primary, 10V/20V secondary configurations, 110mA/55mA output currents) and mechanical specifications (34.93mm × 28.58mm × 23.80mm dimensions, through-hole PC pin mounting, 2500Vrms isolation). This equivalence supports drop-in replacement without circuit redesign.

Q: Does the substitution require PCB layout changes?

A: No. Both the 6022-020 and 6022R-020 feature identical through-hole PC pin termination and physical footprints. Board layout and land patterns require no modification.

Q: Are there compliance differences between the parts?

A: Yes. The 6022R-020 is ROHS3 compliant while the 6022-020 is RoHS non-compliant. For applications requiring RoHS compliance, the 6022R-020 is the appropriate selection. Both parts are REACH unaffected.

Q: What is the difference between the "6022" and "6022R" series designations?

A: The "6022R" designation indicates an active production series manufactured under current compliance standards, while the "6022" designation marks the obsolete generation. The electrical and mechanical specifications remain identical across both series.

Q: Is the 6022R-020 available for immediate use?

A: Yes. The 6022R-020 maintains active product status with 1148 units in current inventory, providing assured supply chain availability compared to the obsolete 6022-020.
