Substitute Part Grouping Explanation

The substitute part A-KEY-8-EG-GIB-WIB1 qualifies as an equivalent based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Manufacturer: Assmann WSW Components (same manufacturer ensures design compatibility)
• Category: Keystone Connectors (identical product category)
• Style: Modular (same connector style)
• Exterior Type: Modular Jack 8p8c (RJ45, Ethernet) (identical interface)
• Interior Type: IDC, Pressdown, Punchdown Block (identical termination method)
• Exterior Housing Color: Blue (same color specification)
• Exterior Contact Material: Phosphor Bronze (same material)
• Interior Contact Material: Phosphor Bronze (same material)
• Exterior Contact Finish: Gold (same finish)
• Ratings: Cat5e (same electrical rating)
• Moisture Sensitivity Level: 1 (Unlimited) (same MSL classification)
• REACH Status: REACH Unaffected (same compliance status)
• ECCN: EAR99 (same export classification)

Differing Parameters (Within Acceptable Tolerance):

• Product Status: Active (substitute is in active production, addressing obsolescence)
• Exterior Housing Material: Polycarbonate (PC) vs. Acrylonitrile Butadiene Styrene (ABS) (both are thermoplastic polymers suitable for connector housings)
• Interior Housing Material: Polybutylene Terephthalate (PBT), Glass Filled vs. Polycarbonate (PC) (PBT glass-filled provides enhanced mechanical properties)
• Interior Housing Color: Blue vs. unspecified (both are blue)
• Interior Contact Finish: Nickel vs. Tin (both are standard contact finishes for IDC applications)
• Operating Temperature Range: 0°C ~ 70°C vs. -10°C ~ 60°C (substitute has wider upper temperature limit)
• Exterior Contact Finish Thickness: 6µin (0.15µm) vs. 50µin (1.27µm) (both meet industry standards for gold plating)

Parameter Comparison

Engineering Selection Recommendations

A-KEY-8-EG-GIB-WIB1 is the direct equivalent substitute for DN-93501-U/B. The substitute part is manufactured by the same supplier and maintains identical functional specifications for RJ45 Ethernet to IDC punchdown block interfacing. The primary advantage of the substitute is its active product status, ensuring continued availability and supply chain support.

The substitute part carries ROHS3 compliance certification, providing enhanced environmental regulatory alignment compared to the obsolete original part. The material composition changes (PC to PBT glass-filled for interior housing, ABS to PC for exterior housing) represent engineering improvements that maintain mechanical and electrical performance while extending the upper operating temperature limit to 70°C.

Both parts maintain identical electrical ratings (Cat5e), contact materials (Phosphor Bronze), and moisture sensitivity classifications. The contact finish specifications differ in thickness but both conform to industry standards for connector applications. Selection of the substitute part is appropriate for all applications previously served by DN-93501-U/B.

Frequently Asked Questions (FAQ)

Q: Can A-KEY-8-EG-GIB-WIB1 be used as a direct replacement for DN-93501-U/B in existing designs?

A: Yes. Both parts share identical exterior and interior connector types (RJ45 to IDC punchdown block), contact materials, electrical ratings (Cat5e), and termination methods. The housing material differences do not affect functional compatibility or electrical performance.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part is in active production, ensuring long-term component availability for procurement and field replacements. The original part's obsolete status indicates discontinued manufacturing and limited remaining inventory.

Q: How do the housing material changes affect performance?

A: The substitute uses Polycarbonate (PC) for exterior housing and Polybutylene Terephthalate (PBT) glass-filled for interior housing, compared to ABS and PC in the original. These materials maintain equivalent mechanical properties and electrical performance while providing improved thermal stability, as evidenced by the extended operating temperature range (0°C ~ 70°C vs. -10°C ~ 60°C).

Q: Are there compliance differences between the two parts?

A: The substitute part carries ROHS3 compliance certification. Both parts maintain identical REACH Unaffected status and EAR99 export classification. The substitute's ROHS3 compliance provides enhanced environmental regulatory alignment.

Q: What is the difference between Tin and Nickel contact finishes on the interior contacts?

A: Both Tin and Nickel are standard contact finish materials for IDC punchdown block applications. The substitute's Nickel finish is a common alternative that provides equivalent electrical performance and corrosion resistance for this connector type.

Q: Does the difference in exterior contact finish thickness affect electrical performance?

A: No. Both 50µin (1.27µm) and 6µin (0.15µm) gold plating thicknesses meet industry standards for connector applications and provide equivalent electrical conductivity and corrosion protection for RJ45 interfaces.

Q: What packaging is available for the substitute part?

A: A-KEY-8-EG-GIB-WIB1 is supplied in Bag packaging, compared to unspecified packaging for the original part.
