API Delevan 6053-040 Equivalent & Substitute Parts

Part Overview

The API Delevan 6053-040 is a laminated core power transformer rated at 12VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations through parallel (20V, 400mA) or series (40V, 200mA) winding connections. The 6053-040 is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6053-040 is determined by electrical and mechanical parameter equivalence. The substitute part must maintain identical specifications across the following critical parameters:

• Power rating (12VA)
• Primary voltage selection (115V, 230V dual primary)
• Secondary voltage outputs in both parallel (20V) and series (40V) configurations
• Output current capacity (400mA parallel, 200mA series)
• Winding configuration (dual primary, dual secondary, no center tap)
• Isolation voltage (1500Vrms)
• Mounting and termination style (through-hole PC pin)
• Physical envelope (34.93mm L × 28.58mm W × 30.15mm H maximum)

The 6053R-040 satisfies all electrical and mechanical equivalence criteria, with the primary distinction being active product status and RoHS3 compliance.

Engineering Selection Recommendations

The 6053R-040 is the direct functional equivalent of the 6053-040. Selection of the 6053R-040 is appropriate for the following conditions:

Product Status Consideration: The 6053-040 is obsolete. The 6053R-040 maintains active product status with established supply chain availability (730 pieces in stock versus 657 for the obsolete variant).

Regulatory Compliance: The 6053R-040 is RoHS3 compliant, whereas the 6053-040 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 6053R-040 is the required selection.

Electrical and Mechanical Compatibility: All electrical parameters, physical dimensions, mounting configuration, and termination style are identical between the two parts. Direct substitution is electrically and mechanically valid without circuit modification or PCB redesign.

Supply Chain: The 6053R-040 offers superior long-term availability as an active product line component.

Frequently Asked Questions (FAQ)

Q: Can the 6053R-040 replace the 6053-040 in existing designs without modification?

A: Yes. The 6053R-040 is electrically and mechanically identical to the 6053-040. No circuit changes, PCB modifications, or functional adjustments are required. The component occupies the same physical envelope and provides identical electrical performance.

Q: What is the primary difference between these two parts?

A: The 6053R-040 is the active production equivalent of the obsolete 6053-040. The substitute offers RoHS3 compliance, improved supply availability, and ongoing manufacturer support. All electrical and mechanical specifications are identical.

Q: Are the dual primary and secondary windings configured identically in both parts?

A: Yes. Both the 6053-040 and 6053R-040 feature dual primary windings (115V/230V selectable) and dual secondary windings (20V parallel or 40V series configuration). Winding polarity, isolation voltage (1500Vrms), and current capacity are identical.

Q: Does the through-hole PC pin termination remain the same?

A: Yes. Both parts use identical through-hole PC pin termination. PCB footprint and assembly process are unchanged.

Q: Is RoHS compliance a functional difference?

A: RoHS compliance is a material composition specification, not a functional electrical difference. The 6053R-040 meets RoHS3 requirements through material selection while maintaining identical electrical performance and physical characteristics.

Q: What inventory status should influence component selection?

A: The 6053R-040 is the recommended selection for new designs and ongoing production. The 6053-040 is obsolete and should be replaced in active designs. The 6053R-040 has established supply availability (730 units in stock).
