6447-024 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The 6447-024 is a 30VA laminated core power transformer manufactured by API Delevan Inc., designed for through-hole mounting applications. This transformer features dual primary windings (115V/230V) and dual secondary windings (12V parallel/24V series configuration), delivering maximum output currents of 2.5A in parallel mode and 1.25A in series mode.

The 6447-024 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The substitute part 6447R-024 provides direct functional equivalence while offering active product status and improved compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6447-024 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Power rating: 30VA
• Primary voltage configuration: 115V/230V dual winding
• Secondary voltage configuration: Parallel 12V/Series 24V dual winding
• Maximum output current: Parallel 2.5A/Series 1.25A
• Isolation voltage: 4000Vrms

Mechanical Parameters (Non-negotiable):

• Core type: Laminated
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 66.68mm L × 55.55mm W × 39.67mm H (Max)

The 6447R-024 meets all specified electrical and mechanical parameters identically to the 6447-024, establishing direct substitution compatibility.

Engineering Selection Recommendations

The 6447R-024 serves as the direct functional equivalent to the 6447-024 for all electrical and mechanical applications. Selection between these parts should be based on the following criteria:

Use 6447-024 when:

• Existing inventory stock is available and procurement lead times are critical
• Legacy system documentation explicitly specifies this part number
• RoHS compliance is not a system requirement

Use 6447R-024 when:

• New designs or system refreshes are being implemented
• RoHS3 compliance is required by design specifications or regulatory requirements
• Long-term product availability and supply chain stability are priorities
• Active product status ensures continued manufacturer support and documentation access

Both parts are manufactured by API Delevan Inc. and carry identical electrical performance characteristics, isolation voltage ratings, and physical form factors suitable for through-hole PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 6447R-024 be used as a direct replacement for the 6447-024 in existing assemblies?

A: Yes. The 6447R-024 is electrically and mechanically identical to the 6447-024. All electrical parameters (power rating, voltage configurations, current ratings, isolation voltage) and physical dimensions match exactly. Through-hole mounting and PC pin termination are identical, enabling direct PCB substitution without layout modifications.

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

A: The 6447R-024 is the active production equivalent of the obsolete 6447-024. The key differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant). All functional and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 6447R-024 for the 6447-024?

A: No compatibility concerns exist. Both parts feature identical dual primary windings (115V/230V), dual secondary windings (12V parallel/24V series), and 4000Vrms isolation voltage. Physical dimensions and mounting characteristics are identical, ensuring seamless integration into existing circuit designs.

Q: Why would I choose the 6447-024 over the 6447R-024?

A: The 6447-024 should only be selected if existing inventory is available and immediate procurement is necessary. Since the 6447-024 is obsolete, future availability cannot be guaranteed. The 6447R-024 is the recommended choice for new designs and ongoing production due to active product status and ROHS3 compliance.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both the 6447-024 and 6447R-024 deliver identical electrical characteristics, output current ratings, and isolation voltage specifications.

Q: Are both parts suitable for 115V and 230V primary applications?

A: Yes. Both the 6447-024 and 6447R-024 feature dual primary windings supporting both 115V and 230V input configurations. Secondary output can be configured as 12V (parallel mode, 2.5A maximum) or 24V (series mode, 1.25A maximum).
