Qualtek 858-10/026 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The Qualtek 858-10/026 is a power entry connector receptacle designed for IEC 320-C14 applications. This component functions as a filtered AC power inlet with male blades, rated for 10A at 115/250VAC, and is configured for panel mount installation with solder termination. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The Qualtek 858-10/015 qualifies as a direct substitute for the 858-10/026 based on the following critical parameters:

• Identical connector style (IEC 320-C14) and type (Receptacle, Male Blades)
• Matching electrical ratings: 10A current and 115/250VAC voltage
• Identical number of positions (3)
• Identical filter configuration (Filtered EMI/RFI - Commercial) with matching 10A filter rating
• Identical mounting type (Panel Mount, Flange)
• Identical regulatory approvals (CSA, UL, VDE)
• Identical RoHS3 compliance status

The primary differences between these parts are termination method (solder versus quick connect) and panel cutout dimensions, which are application-specific considerations rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

The Qualtek 858-10/015 is the designated substitute for the obsolete 858-10/026. Both parts maintain identical electrical specifications, filtering characteristics, and regulatory certifications (CSA, UL, VDE). The 858-10/015 is currently in active production status with higher inventory availability (1621 units versus 716 units for the main part).

Selection between these parts depends on termination requirements: the 858-10/026 uses solder termination while the 858-10/015 uses quick connect termination. Panel cutout dimensions differ slightly and must be evaluated against specific mechanical design constraints. Both parts satisfy ROHS3 compliance and carry equivalent regulatory approvals.

Frequently Asked Questions (FAQ)

Q: Can the 858-10/015 replace the 858-10/026 in existing designs?

A: Yes, provided the quick connect termination method is compatible with the application. The electrical and filtering characteristics are identical. Panel cutout dimensions must be verified against mechanical specifications.

Q: What is the primary reason for substitution?

A: The 858-10/026 is obsolete. The 858-10/015 is an active product from the same manufacturer and series with identical functional specifications.

Q: Are there differences in regulatory compliance?

A: No. Both parts carry identical approvals (CSA, UL, VDE) and maintain ROHS3 compliance status.

Q: How do the termination methods differ?

A: The 858-10/026 uses solder termination for permanent PCB attachment. The 858-10/015 uses quick connect termination, allowing tool-free connection and disconnection. Selection depends on application requirements.

Q: Do panel cutout dimensions affect substitution?

A: Panel cutout dimensions differ between the two parts (858-10/026: 30.50mm x 22.86mm; 858-10/015: 28.45mm x 21.60mm). Mechanical design must accommodate the selected part's dimensions.

Q: What is the current rating for both parts?

A: Both parts are rated for 10A at the appliance inlet and 10A through the commercial EMI/RFI filter, with voltage rating of 115/250VAC.
