API Delevan 6494-016 Equivalent & Substitute Parts

Part Overview

The API Delevan 6494-016 is a laminated core power transformer rated at 25VA with dual primary and secondary windings. This component is classified as obsolete and is no longer in active production. The 6494-016 features dual input voltage capability (115V/230V) and configurable output voltage (parallel 8V or series 16V), making it suitable for chassis-mounted applications requiring galvanic isolation at 4000Vrms.

Due to its obsolete status, sourcing new original inventory of the 6494-016 is subject to availability constraints. Identifying active production equivalents ensures long-term supply chain reliability and access to current manufacturing standards.

Substitute Part Grouping Explanation

Substitution of the 6494-016 is based on electrical and mechanical parameter equivalence. The substitute part must satisfy the following criteria:

Electrical Parameters:

• Identical power rating (25VA)
• Matching primary voltage inputs (115V, 230V dual capability)
• Matching secondary voltage outputs in both parallel (8V) and series (16V) configurations
• Equivalent maximum output current specifications (parallel 3.2A, series 1.6A)
• Equivalent isolation voltage rating (4000Vrms)
• Identical winding configuration (dual primary, dual secondary)

Mechanical Parameters:

• Identical core type (laminated)
• Matching physical dimensions (71.44mm L × 47.63mm W)
• Matching seated height (58.74mm maximum)
• Identical mounting type (chassis mount)
• Compatible termination style (solder and quick connect)

The 6494R-016 meets all specified electrical and mechanical parameters and is manufactured by the same original equipment manufacturer (API Delevan Inc.), ensuring form, fit, and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 6494R-016 is the direct active production equivalent of the obsolete 6494-016. Both components are manufactured by API Delevan Inc. and provide identical electrical and mechanical performance across all specified parameters.

Selection Basis:

The 6494R-016 is recommended for new designs and replacement applications because it maintains full compatibility with the 6494-016 while offering the following advantages:

• Active Production Status: The 6494R-016 is in active production, ensuring reliable long-term availability and consistent manufacturing quality.
• Regulatory Compliance: The 6494R-016 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The 6494-016 is RoHS non-compliant.
• Export Classification: The 6494R-016 carries ECCN classification EAR99 with HTSUS code 8504.31.4035, providing clear regulatory documentation for procurement and export purposes.
• Functional Equivalence: All electrical specifications, mechanical dimensions, and termination methods are identical, enabling direct substitution without circuit redesign or mechanical modification.

For applications currently using the 6494-016, transition to the 6494R-016 requires no design changes and provides improved compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the 6494R-016 be used as a direct replacement for the 6494-016 in existing designs?

A: Yes. The 6494R-016 is electrically and mechanically identical to the 6494-016. All voltage ratings, current specifications, winding configurations, physical dimensions, and termination methods are equivalent. Direct substitution is possible without circuit modification or mechanical redesign.

Q: What is the primary difference between the 6494-016 and 6494R-016?

A: The 6494R-016 is the active production successor to the obsolete 6494-016. The primary differences are product status (active versus obsolete) and regulatory compliance (ROHS3 compliant versus non-compliant). Electrical and mechanical specifications are identical.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both the 6494-016 and 6494R-016 share identical dimensions of 71.44mm length × 47.63mm width with a maximum seated height of 58.74mm. Both use chassis mount configuration, ensuring identical PCB layout and mechanical integration.

Q: Do both transformers support the same voltage configurations?

A: Yes. Both transformers feature dual primary windings supporting 115V or 230V input selection and dual secondary windings providing parallel 8V at 3.2A maximum or series 16V at 1.6A maximum output current.

Q: What is the isolation voltage rating for both parts?

A: Both the 6494-016 and 6494R-016 provide 4000Vrms galvanic isolation between primary and secondary windings.

Q: Are the termination methods compatible?

A: Yes. Both transformers use identical termination styles: solder and quick connect. Existing wiring harnesses and connection methods are compatible without modification.

Q: Why should I transition from the 6494-016 to the 6494R-016?

A: The 6494-016 is obsolete and subject to inventory depletion. The 6494R-016 is in active production, ensuring reliable supply chain access. Additionally, the 6494R-016 is ROHS3 compliant and carries current export classification (EAR99), meeting modern regulatory requirements.

Q: Is there any performance difference between the two transformers?

A: No. Both transformers deliver identical electrical performance across all specified parameters: 25VA power rating, voltage outputs, current capacity, isolation voltage, and core characteristics.
