Substitute Part Grouping Explanation

Substitution of the obsolete 6498-020 with the active 6498R-020 is based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical functional parameters:

Electrical Equivalence Criteria:

• Identical power rating (175VA)
• Matching primary voltage options (115V, 230V)
• Identical secondary voltage configurations (Parallel 10V, Series 20V)
• Matching output current ratings (Parallel 17.6A, Series 8.8A)
• Equivalent isolation voltage (4000Vrms)
• Identical winding configurations (Dual primary, Dual secondary)

Mechanical Equivalence Criteria:

• Identical physical dimensions (79.38mm L × 73.03mm W)
• Matching height specification (95.25mm maximum seated height)
• Identical mounting type (Chassis Mount)
• Identical termination style (Solder, Quick Connect)

Compliance Differentiation: The 6498R-020 provides enhanced regulatory compliance status (RoHS3 compliant, REACH unaffected, EAR99 classification) compared to the obsolete 6498-020, while maintaining complete functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 6498R-020 serves as the direct active equivalent for the obsolete 6498-020. Selection of the 6498R-020 is based on the following engineering factors:

Functional Compatibility: All electrical and mechanical parameters are identical between the two components. The 6498R-020 provides equivalent performance in all circuit applications where the 6498-020 was previously specified.

Product Status: The 6498-020 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 6498R-020 maintains active product status with confirmed inventory availability (793 pieces in stock), ensuring reliable component sourcing for current and future production requirements.

Regulatory Compliance: The 6498R-020 achieves RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The 6498-020 is RoHS non-compliant, which may restrict its use in applications subject to RoHS directives or customer compliance specifications.

Export Classification: The 6498R-020 carries EAR99 classification, providing standard export control treatment. This classification supports broader distribution and supply chain flexibility compared to the obsolete designation of the 6498-020.

Physical and Electrical Interchangeability: Identical dimensions and termination styles ensure direct mechanical and electrical substitution without circuit board redesign or mechanical rework.
