Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 718-20/63 is determined by the following critical parameters:

• Connector Style & Type: IEC 320 series receptacle configuration with female sockets
• Mounting Configuration: Panel mount snap-in installation method
• Termination Standard: Quick Connect 0.250" (6.3mm) terminals
• Panel Cutout Compatibility: Rectangular aperture dimensions within acceptable tolerance ranges
• Electrical Ratings: Current and voltage ratings suitable for the application
• Regulatory Compliance: CSA, UL, or equivalent international certifications
• RoHS Compliance: ROHS3 compliant status

The identified substitute parts maintain core functional compatibility through shared mounting methodology, termination style, and regulatory approval frameworks, while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

Qualtek 716W-X2/03: This substitute maintains Qualtek manufacturer continuity and shares identical panel cutout dimensions with the original 718-20/63. The active product status ensures ongoing availability. The 10A/250VAC rating and three-position configuration provide electrical capacity suitable for standard commercial AC inlet applications. Broader regulatory approval (CCC, NEMKO, TUV in addition to CSA, UL) supports international deployment scenarios.

TE Connectivity Corcom Filters 6ESRFC3: This substitute offers enhanced electrical capacity at 15A/250VAC, accommodating higher-power applications. The IEC 320-C14 configuration and three-position design provide functional equivalence through identical termination and mounting methodology. VDE certification addition supports European market requirements. Panel thickness tolerance of 0.102" (2.60mm) requires verification against specific panel specifications.

Both substitutes maintain ROHS3 compliance and unfiltered commercial filter classification consistent with the original component. Selection between alternatives depends on application current requirements and panel thickness specifications.

Frequently Asked Questions (FAQ)

Q: Can the 716W-X2/03 directly replace the 718-20/63 in existing designs?

A: The 716W-X2/03 shares identical panel cutout dimensions (32.26mm x 24.77mm nominal vs. 32.60mm x 25.30mm specified), mounting methodology (panel mount snap-in), and termination standard (Quick Connect 0.250"). The primary design consideration is the increase from 2 to 3 positions and the specified panel thickness range of 0.031" ~ 0.059" (0.79mm ~ 1.50mm), which differs from the original 0.079" (2.00mm) specification. Panel thickness compatibility must be confirmed for the target application.

Q: What are the electrical differences between the substitute options?

A: The 716W-X2/03 provides 10A at 250VAC, while the 6ESRFC3 provides 15A at 250VAC. The original 718-20/63 does not specify electrical ratings. Selection should be based on the actual current requirements of the application. Both substitutes operate at 250VAC, consistent with standard commercial AC inlet specifications.

Q: Are there connector style differences between the substitutes?

A: The 716W-X2/03 uses IEC 320-2-2/F configuration, while the 6ESRFC3 uses IEC 320-C14 configuration. Both are IEC 320 series receptacles with female sockets. The specific connector style must be verified against the mating plug configuration in the target application to ensure physical and electrical compatibility.

Q: Do all substitutes meet the same regulatory requirements?

A: The original 718-20/63 carries CSA and UL approvals. The 716W-X2/03 adds CCC, NEMKO, and TUV certifications to the CSA and UL base. The 6ESRFC3 includes CSA, UL, and VDE approvals. All three components are ROHS3 compliant. Selection should consider the geographic market and specific regulatory requirements of the end application.

Q: What is the impact of the position count increase from 2 to 3?

A: Both substitutes feature three-position configurations compared to the original two-position design. This affects the physical connector interface and the number of available electrical contacts. The mating connector in the application must accommodate the three-position standard to ensure proper electrical connection and mechanical fit.
