API Delevan 6022-056 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The API Delevan 6022-056 is a laminated core power transformer rated at 1.1VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations of 28V parallel or 56V series, with corresponding maximum output currents of 40mA or 20mA respectively. The transformer accepts dual primary voltages of 115V or 230V and features 2500Vrms isolation rating.

The 6022-056 is classified as obsolete product status. Identification of equivalent substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6022-056 are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Must Match):

• Power rating: 1.1VA
• Primary voltage options: 115V, 230V
• Secondary voltage configurations: Parallel 28V, Series 56V
• Maximum output currents: Parallel 40mA, Series 20mA
• Primary winding configuration: Dual
• Secondary winding configuration: Dual
• Isolation voltage: 2500Vrms

Mechanical Parameters (Must Match):

• Core type: Laminated
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 34.93mm L x 28.58mm W
• Maximum seated height: 23.80mm

Compliance Considerations: Substitute parts may differ in product status (active vs. obsolete) and regulatory compliance certifications (RoHS, REACH). These differences do not affect electrical or mechanical compatibility but influence long-term availability and regulatory applicability.

Parameter Comparison

Engineering Selection Recommendations

The 6022R-056 is a direct electrical and mechanical equivalent to the 6022-056. All functional parameters, electrical specifications, and physical dimensions are identical between the two parts.

Key Differentiators:

Product Status: The 6022-056 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 6022R-056 maintains active product status with current manufacturing support and established supply chains.

Regulatory Compliance: The 6022-056 is RoHS non-compliant. The 6022R-056 is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances directives. Both parts maintain identical REACH unaffected status and EAR99 export classification.

Selection Basis: For new designs, production continuity, and applications subject to RoHS compliance requirements, the 6022R-056 is the appropriate selection. The active product status ensures long-term availability and supply reliability. For legacy system maintenance where RoHS compliance is not mandated, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the 6022-056 and 6022R-056 electrically interchangeable?

A: Yes. Both transformers provide identical electrical specifications: 1.1VA power rating, dual 115V/230V primary inputs, dual secondary windings with 28V parallel or 56V series output options, 40mA parallel or 20mA series maximum output current, and 2500Vrms isolation voltage.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical mechanical specifications: 34.93mm length, 28.58mm width, 23.80mm maximum seated height, and 0.17 lb weight. Both use through-hole mounting with PC pin termination, ensuring identical PCB footprint compatibility.

Q: What is the significance of the product status difference?

A: The 6022-056 is obsolete, indicating discontinued production. The 6022R-056 is active, meaning current manufacturing and established distribution channels. For applications requiring long-term component availability, the 6022R-056 is the preferred selection.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and hazardous substance restrictions, not electrical or mechanical function. Both parts deliver identical electrical performance. RoHS compliance becomes relevant only when regulatory requirements mandate it for specific applications or markets.

Q: Can I use the 6022R-056 as a direct replacement in existing designs using the 6022-056?

A: Yes. Identical electrical specifications, physical dimensions, and mounting characteristics ensure direct substitution without circuit modification or PCB redesign.

Q: Are there any inventory or lead time considerations?

A: The 6022-056 has 868 pieces in stock but is obsolete. The 6022R-056 has 941 pieces in stock and maintains active product status, providing greater long-term availability assurance.
