FPQUAD-BK Equivalent & Substitute Parts

Part Overview

The FPQUAD-BK is a single gang 4-port faceplate manufactured by HellermannTyton, designed for use with modular jacks in keystone connector applications. This part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new installations. The FPQUAD-BK maintains the same mechanical and electrical specifications across the product family, with variations limited to material composition and finish color.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FPQUAD-BK is determined by strict adherence to the following parameters:

• Port Configuration: All substitutes must maintain 4 ports in straight orientation
• Form Factor: Single gang style with identical mechanical dimensions (4.500" × 2.756" × 0.217")
• Flammability Compliance: UL94 V-0 rating required
• Moisture Sensitivity: MSL 1 (Unlimited) classification
• Trade Classification: ECCN EAR99 and HTSUS 3926.90.9985 alignment
• Base Product Family: FPQUAD series only

The FPQUAD-BK, FPQUAD-FW, and FPQUAD-SS are functionally equivalent within the FPQUAD base product family. Variations exist only in material composition (ABS plastic versus stainless steel) and color finish, which do not affect electrical or mechanical compatibility with modular jack systems.

Parameter Comparison

Engineering Selection Recommendations

Both FPQUAD-FW and FPQUAD-SS are active product alternatives to the obsolete FPQUAD-BK. Selection between these substitutes depends on application-specific requirements:

FPQUAD-FW (White, Off): Maintains identical ABS material composition and UL94 V-0 flammability rating as the original FPQUAD-BK. This substitute provides direct functional equivalence with RoHS compliance certification. Suitable for applications where material consistency and flammability performance are primary selection criteria.

FPQUAD-SS (Silver): Constructed from stainless steel material, offering enhanced corrosion resistance compared to the ABS-based original. This substitute maintains identical port configuration, dimensions, and MSL classification. RoHS compliant. Suitable for applications requiring superior environmental durability or specific aesthetic requirements.

Both substitutes maintain full compatibility with modular jack systems and preserve all critical electrical and mechanical parameters of the FPQUAD-BK.

Frequently Asked Questions (FAQ)

Q: Can FPQUAD-FW and FPQUAD-SS be used interchangeably with FPQUAD-BK?

A: Yes. Both substitutes maintain identical port configuration (4 ports, straight orientation), mechanical dimensions, MSL classification, and trade designations. Functional compatibility with modular jack systems is preserved.

Q: What is the primary difference between FPQUAD-FW and FPQUAD-SS?

A: Material composition and finish. FPQUAD-FW uses ABS plastic (matching the original FPQUAD-BK material), while FPQUAD-SS uses stainless steel. Both maintain UL94 V-0 or equivalent flammability compliance and RoHS certification.

Q: Why is FPQUAD-BK listed as obsolete?

A: Product status reflects manufacturer discontinuation. Active alternatives (FPQUAD-FW and FPQUAD-SS) remain available for new designs and system maintenance.

Q: Are there any compliance differences between the three parts?

A: FPQUAD-FW and FPQUAD-SS both carry RoHS Compliant certification. All three parts share identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications and MSL 1 (Unlimited) ratings.

Q: Which substitute should I select for a replacement installation?

A: Selection depends on environmental and aesthetic requirements. For direct material equivalence, choose FPQUAD-FW. For enhanced corrosion resistance, choose FPQUAD-SS. Both are functionally equivalent to FPQUAD-BK for modular jack applications.
