Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 718-30/63 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle, Female Sockets
• Mounting configuration: Panel Mount, Snap-In
• Termination standard: Quick Connect - 0.250" (6.3mm)
• Filter classification: Unfiltered - Commercial
• Regulatory compliance: CSA and UL approval

Secondary Compatibility Considerations:

• Panel cutout dimensions must accommodate the original 32.26mm x 24.77mm rectangular opening
• Panel thickness tolerance must support installation
• IEC connector style variants (320-2-2/F, 320-C14) represent different pin configurations but maintain functional receptacle architecture

The identified substitutes maintain core receptacle functionality and mounting methodology while offering active product status and enhanced electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

716W-X2/03 (Qualtek): This substitute maintains Qualtek manufacturer continuity and shares identical termination and mounting architecture. The IEC 320-2-2/F variant provides 3-position configuration with 10A/250VAC ratings. Panel cutout dimensions (32.60mm x 25.30mm) are marginally larger than the original specification. This option is suitable for applications where Qualtek component standardization is required and panel thickness tolerance permits the 0.79mm–1.50mm range. Active product status ensures ongoing availability.

6ESRFC3 (TE Connectivity Corcom Filters): This substitute represents a different manufacturer platform (TE Connectivity) with IEC 320-C14 connector style, offering higher current capacity (15A/250VAC) at 3-position configuration. Panel cutout dimensions (32.26mm x 24.76mm) align closely with the original specification. Panel thickness tolerance (0.102" / 2.60mm) accommodates the original 3.00mm specification. Extended regulatory approvals (CSA, UL, VDE) provide broader compliance coverage. Active product status and higher electrical ratings support applications requiring increased power delivery capacity.

Both substitutes maintain unfiltered commercial classification, quick-connect termination, and panel mount snap-in installation methodology. Selection depends on connector style compatibility with mating plugs, panel thickness constraints, and required electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the 716W-X2/03 directly replace the 718-30/63 in existing designs?

A: The 716W-X2/03 maintains identical mounting methodology (panel mount snap-in) and termination standard (quick connect 0.250"). However, the IEC 320-2-2/F connector style differs from the original IEC 320-2-2/H configuration, requiring verification that mating plugs are compatible with the 3-position variant. Panel cutout dimensions are slightly larger (32.60mm x 25.30mm vs. 32.26mm x 24.77mm), which may require panel modification. Panel thickness tolerance (0.79mm–1.50mm) is narrower than the original specification (3.00mm).

Q: What are the key differences between the two substitute options?

A: The 716W-X2/03 maintains Qualtek manufacturer identity with 10A/250VAC ratings and IEC 320-2-2/F configuration. The 6ESRFC3 offers TE Connectivity manufacturing with higher 15A/250VAC capacity and IEC 320-C14 configuration. Panel cutout dimensions for the 6ESRFC3 (32.26mm x 24.76mm) are nearly identical to the original, while the 716W-X2/03 requires slightly larger opening. Both are active products with ROHS3 compliance.

Q: Are panel cutout dimension differences critical for substitution?

A: Panel cutout dimensions determine whether physical installation is feasible without panel modification. The 6ESRFC3 (32.26mm x 24.76mm) matches the original specification within manufacturing tolerance. The 716W-X2/03 (32.60mm x 25.30mm) requires a larger opening. If the original panel has a precisely machined cutout, the 6ESRFC3 is the preferred option to avoid rework.

Q: What is the significance of panel thickness tolerance differences?

A: Panel thickness tolerance affects snap-in installation security. The original 718-30/63 specifies 0.118" (3.00mm) fixed thickness. The 716W-X2/03 accepts 0.031"–0.059" (0.79mm–1.50mm), which is narrower and may not accommodate thicker panels. The 6ESRFC3 accepts 0.102" (2.60mm), which is closer to the original specification. Verify actual panel thickness before selection.

Q: Do the substitutes maintain the same electrical ratings as the original?

A: The original 718-30/63 does not specify current or voltage ratings. Both substitutes provide rated specifications: 716W-X2/03 at 10A/250VAC and 6ESRFC3 at 15A/250VAC. These ratings apply to the connector receptacle and must be verified against the application's power requirements and mating plug specifications.

Q: Are there regulatory compliance considerations for substitution?

A: The original 718-30/63 carries CSA and UL approvals. The 716W-X2/03 adds CCC, NEMKO, and TUV certifications. The 6ESRFC3 adds VDE certification. All three are ROHS3 compliant. Extended approvals on the substitutes provide broader regulatory coverage and may be advantageous for international applications.
