Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6024-028 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters (Non-Negotiable):

• Power rating: 6VA
• Primary voltage configuration: Dual windings supporting 115V and 230V
• Secondary voltage outputs: Parallel 14V/400mA and Series 28V/200mA
• Isolation voltage: 2500Vrms
• Core type: Laminated

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 41.28mm L × 33.32mm W × 33.32mm H
• Weight: 0.44 lb (199.58 g)

The 6024R-028 meets all substitution criteria as a direct equivalent with identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance.

Engineering Selection Recommendations

For New Designs and Ongoing Production:

The 6024R-028 is the appropriate selection for new applications and production continuity. This part maintains complete electrical and mechanical equivalence to the 6024-028 while offering the following advantages:

• Active Product Status: The 6024R-028 is classified as active, ensuring long-term availability and manufacturer support.
• Regulatory Compliance: ROHS3 compliance satisfies current environmental and regulatory requirements for component procurement in most jurisdictions.
• Functional Equivalence: All electrical parameters, winding configurations, and mechanical specifications are identical, enabling direct substitution without circuit redesign.

For Legacy System Maintenance:

The original 6024-028 remains available in inventory (1120 units) for maintenance and repair of existing installations where RoHS non-compliance is not a constraint. However, new procurement should transition to the 6024R-028 to align with current compliance standards and ensure future availability.

Frequently Asked Questions (FAQ)

Q: Can the 6024R-028 be used as a direct replacement for the 6024-028 in existing designs?

A: Yes. The 6024R-028 is electrically and mechanically identical to the 6024-028. All primary and secondary voltage configurations, current ratings, winding arrangements, mounting type, termination style, and physical dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between the 6024 and 6024R series designations?

A: The 6024R designation indicates the active production variant with ROHS3 compliance. The 6024 designation refers to the obsolete version. Both series share identical electrical and mechanical specifications.

Q: Are there any compatibility concerns when substituting the 6024R-028 for the 6024-028?

A: No compatibility concerns exist. The parts are pin-compatible, dimensionally identical, and functionally equivalent. PCB layouts, mounting holes, and component spacing require no modification.

Q: Why should new designs use the 6024R-028 instead of the 6024-028?

A: The 6024-028 is obsolete and RoHS non-compliant. The 6024R-028 is an active product with ROHS3 compliance, ensuring regulatory alignment, long-term availability, and manufacturer support for new applications.

Q: What is the isolation voltage specification, and does it differ between the two parts?

A: Both the 6024-028 and 6024R-028 provide 2500Vrms isolation voltage. This specification is identical across both parts.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts measure 41.28mm L × 33.32mm W × 33.32mm H and use through-hole PC pin termination. PCB layouts designed for the 6024-028 require no modification for the 6024R-028.

Q: What inventory levels are available for each part?

A: The 6024-028 has 1120 units in stock. The 6024R-028 has 936 units in stock. Both are available as new original components.
