Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-6610023-1 are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Connector Type: RJ45 modular jack
• Number of Ports: 4-port configuration
• Mounting Type: Through hole solder termination
• Orientation: 90° right-angle
• Shielding: Shielded with EMI finger protection
• Applications: 10/100 Base-T Ethernet with AutoMDIX support
• Number of Rows: Single row

Substitution Categories:

Direct Equivalent: Parts that maintain all critical electrical and mechanical parameters with active product status and current availability.

Similar Substitute: Parts that satisfy core functional requirements (4-port RJ45, through-hole, 90° orientation, shielded) with minor parameter variations in non-critical specifications such as LED color configuration, tab direction, or contact finish thickness.

Parameter Comparison

Engineering Selection Recommendations

1-6610049-1 (TRP Connector B.V.) - Direct Equivalent:

The 1-6610049-1 is the primary substitute for the obsolete 1-6610023-1. This part maintains identical mechanical dimensions (0.555" height), electrical configuration (4-port RJ45, 10/100 Base-T with AutoMDIX), and contact specifications (phosphor bronze with 50.0µin gold finish). The part is currently active with ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs. The operating temperature range of 0°C to 70°C is narrower than the original part; applications requiring the full -40°C to 85°C range require thermal evaluation.

SS-748804S-GR-PG4-BZ (Stewart Connector) - Similar Substitute:

The SS-748804S-GR-PG4-BZ functions as a compatible alternative for applications where the primary equivalent is unavailable. This part satisfies all core functional requirements: 4-port RJ45 through-hole configuration, 90° right-angle orientation, shielded design with EMI finger protection, and solder termination. The part maintains the full -40°C to 85°C operating temperature range of the original. Differences include copper alloy contact material (versus phosphor bronze), reduced contact finish thickness (30.0µin versus 50.0µin), green-red LED configuration (versus green-green), and downward tab direction (versus upward). The part is ROHS3 compliant and REACH unaffected. These variations do not affect functional compatibility for standard 10/100 Base-T Ethernet applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-6610049-1 be used as a direct replacement for the 1-6610023-1 in all applications?

A: The 1-6610049-1 is mechanically and electrically compatible with the 1-6610023-1 for standard 10/100 Base-T Ethernet applications. The primary consideration is the operating temperature range: the 1-6610049-1 operates from 0°C to 70°C, while the original part operates from -40°C to 85°C. Applications requiring operation below 0°C or above 70°C require thermal analysis or selection of an alternative part.

Q: What are the key differences between the 1-6610049-1 and SS-748804S-GR-PG4-BZ?

A: Both parts are functionally compatible 4-port RJ45 through-hole connectors with 90° orientation and shielded design. The 1-6610049-1 uses phosphor bronze contacts with 50.0µin gold finish and upward tab direction. The SS-748804S-GR-PG4-BZ uses copper alloy contacts with 30.0µin gold finish and downward tab direction. The 1-6610049-1 features green-green LEDs; the SS-748804S-GR-PG4-BZ features green-red LEDs. The SS-748804S-GR-PG4-BZ maintains the full -40°C to 85°C operating temperature range.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the 1-6610049-1 and SS-748804S-GR-PG4-BZ are ROHS3 compliant and REACH unaffected. The original 1-6610023-1 has undefined RoHS and REACH status due to its obsolete classification.

Q: Does the reduced contact finish thickness on the SS-748804S-GR-PG4-BZ affect reliability?

A: The SS-748804S-GR-PG4-BZ specifies 30.0µin (0.76µm) contact finish thickness compared to 50.0µin (1.27µm) on the original and direct equivalent. Both thicknesses are within industry standards for gold-plated connectors in 10/100 Base-T applications. The reduced thickness does not compromise functional performance for standard Ethernet applications.

Q: Can the SS-748804S-GR-PG4-BZ be used in applications requiring the full -40°C to 85°C temperature range?

A: Yes. The SS-748804S-GR-PG4-BZ maintains the full -40°C to 85°C operating temperature range of the original 1-6610023-1, making it suitable for extended temperature applications where the 1-6610049-1 (0°C to 70°C) is not appropriate.

Q: What is the significance of the tab direction difference between substitute parts?

A: Tab direction (up versus down) affects the mechanical orientation of the connector's retention mechanism on the PCB. The 1-6610049-1 maintains the upward tab direction of the original part. The SS-748804S-GR-PG4-BZ features downward tab direction. PCB layout and mechanical clearance requirements determine which tab direction is suitable for a specific application.

Q: Are the LED color differences between substitute parts functionally significant?

A: LED color differences (green-green versus green-red) are cosmetic and do not affect electrical functionality. Selection between parts should be based on visual indication requirements for the application. The 1-6610049-1 maintains the green-green configuration of the original part.
