Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI-62004-F are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Connector Type: RJ45 (8p8c modular jack)
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded configuration
• Tab Direction: Down
• Contact Finish: Gold plating
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

All four substitute parts meet these core electrical and mechanical parameters, enabling direct substitution in PCB designs specified for the SI-62004-F without requiring layout or schematic modifications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet ROHS3 compliance requirements, ensuring regulatory alignment with current environmental standards. The SI-62004-F, 7499011002A, A63-113-300P422, and ARJ11B-MASAA-MU2 are all ROHS3 compliant, while 6116526-1 carries RoHS compliance certification.

Inventory Availability:

• SI-62004-F (Stewart Connector): 699 units
• 6116526-1 (TE Connectivity): 80,498 units
• 7499011002A (Würth Elektronik): 773 units
• A63-113-300P422 (Mercury United): 709 units
• ARJ11B-MASAA-MU2 (Abracon LLC): 827 units

Contact Finish Thickness Consideration: Contact finish thickness varies across substitute parts, ranging from 6.00µin to 50.0µin. The SI-62004-F and 6116526-1 both specify 50.0µin thickness, providing maximum contact durability. Parts with lower thickness ratings (7499011002A at 30.0µin, A63-113-300P422 at 15.0µin, and ARJ11B-MASAA-MU2 at 6.00µin) remain within acceptable parameters for 10/100 Base-T applications but may have reduced contact life in high-cycle mating environments.

Operating Temperature Range: The 6116526-1 supports the widest operating temperature range (-40°C to 85°C), suitable for extended environmental conditions. The remaining substitutes (7499011002A, A63-113-300P422, and ARJ11B-MASAA-MU2) operate within 0°C to 70°C, appropriate for standard commercial and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can 6116526-1 be used as a direct replacement for SI-62004-F?

A: Yes. The 6116526-1 meets all core substitution criteria: RJ45 connector type, 1-port configuration, through-hole mounting, 90° right-angle orientation, solder termination, shielded design, and gold contact finish. The primary difference is operating temperature range (-40°C to 85°C versus unspecified for SI-62004-F) and contact finish thickness (50.0µin matching specification).

Q: What are the key differences between 7499011002A and A63-113-300P422?

A: Both parts are functionally equivalent for 10/100 Base-T applications. The 7499011002A (Würth Elektronik) offers 30.0µin contact finish thickness and 0°C to 70°C operating range. The A63-113-300P422 (Mercury United) provides 15.0µin contact finish thickness and identical operating temperature range. Height above board differs slightly (13.75mm versus 13.49mm), which may affect PCB layout considerations.

Q: Is ARJ11B-MASAA-MU2 suitable for high-reliability applications?

A: The ARJ11B-MASAA-MU2 meets all core electrical and mechanical substitution parameters and maintains ROHS3 compliance and MSL 1 rating. However, the 6.00µin contact finish thickness is the lowest among substitute options, which may impact contact durability in applications requiring extended mating cycles or harsh environmental exposure.

Q: What packaging formats are available for these substitute parts?

A: SI-62004-F packaging is not specified. Substitute parts are available in: 6116526-1 (Tray), 7499011002A (Tube), A63-113-300P422 (Tray), and ARJ11B-MASAA-MU2 (Tray). Packaging selection should align with assembly process requirements and inventory management protocols.

Q: Are all substitute parts REACH compliant?

A: SI-62004-F, 7499011002A, A63-113-300P422, and ARJ11B-MASAA-MU2 are REACH Unaffected. The 6116526-1 carries Vendor Undefined REACH status, requiring verification with TE Connectivity for specific regulatory applications.
