Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1840882-1 connector is determined by the following critical parameters:

Electrical Compatibility:

• Connector Type: RJ45 (8-core jack configuration)
• Application Support: 10/100/1000 Base-T with AutoMDIX capability
• Number of Ports: 1 port configuration

Mechanical Compatibility:

• Mounting Type: Through Hole PCB mounting
• Orientation: 90° right-angle configuration
• Height Above Board: 0.460" (11.68mm) or equivalent

Physical & Environmental:

• Shielding: Shielded design with EMI finger protection
• Operating Temperature Range: 0°C ~ 70°C
• Contact Material & Finish: Phosphor Bronze with Gold plating
• Features: Board Guide and Light Pipe functionality

Regulatory & Compliance:

• RoHS3 Compliance required
• MSL Level 1 (Unlimited moisture sensitivity)

The substitute part 2250471-4 from TRP Connector B.V. maintains functional equivalence within these parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

The 1840882-1 is classified as Obsolete, indicating discontinued manufacturing and limited long-term availability. The substitute part 2250471-4 is currently Active status, ensuring continued supply chain access and manufacturing support from TRP Connector B.V.

Both parts maintain RoHS3 compliance and are manufactured by the same supplier, supporting design continuity. Selection between the main part and substitute should prioritize the Active status part (2250471-4) for new designs and long-term production requirements. Existing inventory of the 1840882-1 may be retained for legacy system maintenance where specific design constraints require the original part number.

Frequently Asked Questions (FAQ)

Q: Can the 2250471-4 directly replace the 1840882-1 in existing PCB designs?

A: Both parts are RJ45 Through Hole modular connectors from TRP Connector B.V. with 1 port configuration. Direct mechanical and electrical compatibility is supported when the substitute part maintains the specified mounting type, orientation, and electrical application parameters. PCB footprint verification is required prior to implementation.

Q: What is the significance of the Obsolete product status for the 1840882-1?

A: Obsolete status indicates the manufacturer has discontinued production. While existing inventory may be available, future procurement cannot be guaranteed. The Active status of 2250471-4 ensures ongoing manufacturing availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS3 compliant and manufactured by TRP Connector B.V. under equivalent regulatory frameworks. Compliance certifications remain consistent across the substitution.

Q: What parameters must remain constant for substitution validity?

A: Critical parameters include Connector Type (RJ45), Mounting Type (Through Hole), Port Configuration (1 port), Shielding (Shielded with EMI Finger), and Application Support (10/100/1000 Base-T). Deviations in these parameters invalidate substitution compatibility.

Q: How should inventory decisions be made between the two parts?

A: For new designs and production runs, prioritize the Active part (2250471-4) to ensure supply continuity. Existing 1840882-1 inventory may be reserved for legacy system support or maintenance applications where the original part number is specifically required.
