NK4RMFEI Equivalent & Substitute Parts

Part Overview

The NK4RMFEI is a 4 Port Module Frame (106 Duplex) in Electric Ivory color, designed for single gang wall plate applications within the NetKey® Series keystone connector system. This component serves as a faceplate assembly that accommodates four duplex keystone modules in a standard single gang electrical box configuration.

The NK4RMFEI is classified as obsolete. Identification of equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for installations, replacements, and new deployments where this specific color variant may no longer be in active production.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NK4RMFEI is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Type: Module Frame (106 Duplex)
• Style: Single Gang
• Number of Ports: 4
• Port Direction: Straight
• Dimensions: Length 4.063" (103.20mm), Width 1.425" (36.20mm), Depth 0.453" (11.50mm)

System Compatibility Parameters:

• Series: NetKey®
• Category: Keystone Connectors

Regulatory & Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• ECCN: EAR99

The NK4RMFWH (White variant) maintains identical mechanical dimensions, port configuration, and system compatibility. The primary difference is color designation (Electric Ivory versus White). Both parts share the same base product number (NK4RMF) and are designed for identical installation environments and functional applications.

Parameter Comparison

Engineering Selection Recommendations

The NK4RMFWH serves as the active production equivalent to the obsolete NK4RMFEI. Both parts are manufactured by Panduit Corp and maintain full compliance with ROHS3 regulations and EAR99 export classification requirements.

For applications requiring the NK4RMFEI:

The NK4RMFWH is the direct functional substitute. It provides identical mechanical fit, electrical performance, and system integration within NetKey® installations. The NK4RMFWH is currently in active production status with confirmed inventory availability (686 pieces), whereas the NK4RMFEI is obsolete with limited remaining stock (828 pieces).

Compliance Considerations:

Both parts satisfy ROHS3 compliance requirements and are classified under EAR99 for export control purposes. No additional regulatory barriers exist for substitution between these two variants.

Inventory & Availability:

The NK4RMFWH represents the recommended selection path for new procurements and long-term system planning due to its active product status and established supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can NK4RMFWH be used as a direct replacement for NK4RMFEI in existing installations?

A: Yes. The NK4RMFWH is mechanically and functionally equivalent to the NK4RMFEI. Both parts share identical dimensions (4.063" × 1.425" × 0.453"), port configuration (4 ports, straight direction), and are designed for single gang wall plate mounting within the NetKey® Series system. The only difference is color designation.

Q: What is the significance of the color difference between Electric Ivory and White?

A: Color is an aesthetic specification that does not affect electrical performance, mechanical compatibility, or functional operation. Selection between Electric Ivory and White depends on installation environment requirements and aesthetic preferences. Both colors are manufactured from ABS material with identical physical properties.

Q: Why is NK4RMFEI classified as obsolete?

A: Product obsolescence indicates that the NK4RMFEI is no longer in active production. Panduit Corp has transitioned to the NK4RMFWH as the current production variant. Existing inventory of NK4RMFEI remains available but is finite.

Q: Are there any compatibility issues when substituting NK4RMFWH for NK4RMFEI?

A: No compatibility issues exist. Both parts conform to the same NetKey® Series specifications, support identical 106 Duplex module configurations, and maintain the same physical mounting interface. Installation procedures and electrical performance remain unchanged.

Q: What is the base product number relationship?

A: Both NK4RMFEI and NK4RMFWH share the base product number NK4RMF. The suffix designates the color variant: EI for Electric Ivory, WH for White. This nomenclature structure indicates that both parts are variants of the same core product design.

Q: Are both parts ROHS3 compliant?

A: Yes. Both NK4RMFEI and NK4RMFWH are ROHS3 compliant and carry EAR99 export classification. No regulatory differences exist between the two parts.

Q: What packaging format is available for these parts?

A: Both parts are supplied in bulk packaging format, suitable for integration into larger assembly operations or direct installation applications.
