Equivalent & Substitute Parts for TIC-L033-11

Part Overview

The TIC-L033-11 is a 1 Port RJ45 Through Hole modular connector manufactured by Tamura, designed for 10/100 Base-TX applications. This connector features a 90° right-angle orientation with solder termination, shielded construction with EMI finger protection, and integrated LED indicators (Green, Orange-Yellow). The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for 10/100 Ethernet networking applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIC-L033-11 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: RJ45 (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Orientation: 90° Angle Right (mandatory match)
• Termination: Solder (mandatory match)
• Shielding: Shielded construction (mandatory match)
• Applications: 10/100 Base-T or 10/100 Base-TX (functionally equivalent for Ethernet networking)

Secondary Compatibility Criteria:

• Number of Ports: 1 (mandatory match)
• Tab Direction: Up (mandatory match)
• Contact Finish: Gold (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)

The three Stewart Connector MagJack® ST SI-50000 series parts listed below satisfy these criteria. All substitute parts are active products with current manufacturing status, providing long-term availability compared to the obsolete TIC-L033-11.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TIC-L033-11 is classified as obsolete. All three substitute parts (SI-50141-F, SI-50163-F, SI-50211-F) maintain active product status with current manufacturing support, ensuring long-term component availability and supply chain continuity.

Compliance & Certification: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The TIC-L033-11 does not specify RoHS compliance status.

Mechanical & Electrical Compatibility: All substitute parts match the critical parameters of the TIC-L033-11: RJ45 connector type, single port, through-hole mounting, 90° right-angle orientation, solder termination, shielded construction, and gold contact finish. Height above board differs by 0.019" (0.48mm) across all substitutes, which is within typical PCB layout tolerances for through-hole connectors.

Application Compatibility: The TIC-L033-11 specifies 10/100 Base-TX operation. The substitute parts specify 10/100 Base-T operation, which is functionally equivalent for standard Ethernet networking. Two substitutes (SI-50141-F and SI-50211-F) include AutoMDIX capability, providing automatic medium-dependent interface crossover detection.

Selection Guidance:

• SI-50163-F is the closest functional equivalent, supporting 10/100 Base-T with 5 cores per jack (matching the TIC-L033-11 core count) and standard LED indicators (Yellow-Green).
• SI-50141-F and SI-50211-F provide AutoMDIX functionality with 4 cores per jack, suitable for applications requiring automatic cable type detection.

Frequently Asked Questions (FAQ)

Q: Can SI-50141-F, SI-50163-F, or SI-50211-F be used as direct replacements for TIC-L033-11 in existing designs?

A: Yes, all three parts are functionally compatible substitutes. They share identical connector type (RJ45), mounting method (through-hole), orientation (90° right-angle), termination (solder), and shielding characteristics. The 0.019" height difference is within standard PCB layout tolerances. Verify that your application does not require the specific 10/100 Base-TX designation; 10/100 Base-T operation is functionally equivalent for standard Ethernet networking.

Q: What is the difference between 10/100 Base-TX and 10/100 Base-T?

A: Both support 10 Mbps and 100 Mbps Ethernet operation. Base-TX specifically refers to twisted-pair transmission. Base-T is a broader classification encompassing twisted-pair implementations. For standard Ethernet applications, these are functionally equivalent.

Q: Why do SI-50141-F and SI-50211-F have 4 cores while SI-50163-F has 5 cores, compared to the TIC-L033-11's 5 cores?

A: Core count reflects the internal jack configuration. The TIC-L033-11 and SI-50163-F both support 5-core configurations. SI-50141-F and SI-50211-F use 4-core configurations with AutoMDIX functionality. For standard 10/100 Ethernet applications, both configurations are compatible. Verify your application requirements before selection.

Q: Are the Stewart Connector substitutes RoHS compliant?

A: Yes, all three Stewart Connector parts (SI-50141-F, SI-50163-F, SI-50211-F) are ROHS3 compliant and REACH unaffected. The original TIC-L033-11 does not specify RoHS compliance status.

Q: What is the significance of the contact finish thickness difference (30.0µin vs. 50.0µin)?

A: The substitute parts feature thicker gold plating (50.0µin) compared to the TIC-L033-11 (30.0µin). Thicker plating provides enhanced durability and corrosion resistance, representing an improvement in contact reliability and longevity.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts share identical through-hole mounting footprints, 90° right-angle orientation, and solder termination. The 0.019" height variation is negligible for standard PCB assembly processes. Verify LED color requirements for your application, as indicator colors vary across the substitute options.

Q: What inventory status should I consider for procurement?

A: Current inventory levels are: TIC-L033-11 (970 pcs), SI-50141-F (971 pcs), SI-50163-F (956 pcs), SI-50211-F (702 pcs). However, the TIC-L033-11 is obsolete and represents existing stock only. The Stewart Connector parts are active products with ongoing manufacturing support, ensuring future availability.
