Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-2004-2-2-LP/S-R is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Must be Jack type with 8p8c (RJ45, Ethernet) contact arrangement
• Physical Orientation & Mounting: Must maintain 90° right-angle orientation with through-hole solder termination
• Electrical & Mechanical Protection: Must include shielding and feature board lock with panel stops
• Material & Environmental Specifications: Must use phosphor bronze contacts with gold finish, PBT housing, and support -40°C ~ 85°C operating range
• Moisture Sensitivity: Must maintain MSL 1 classification

The substitute part 5555153-1 (TE Connectivity AMP Connectors) meets all these criteria and is classified as an MFR (Manufacturer) Recommended substitute.

• Availability: The substitute maintains higher inventory levels (3722 Pcs) compared to the original part (942 Pcs), supporting production continuity

For applications requiring the A-2004-2-2-LP/S-R, direct substitution with 5555153-1 is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can 5555153-1 be used as a direct replacement for A-2004-2-2-LP/S-R?

A: Yes. Both connectors share identical connector type, contact configuration (8p8c RJ45), orientation (90° right-angle), mounting method (through-hole solder), shielding, and operating temperature range. The substitute is MFR recommended and requires no design changes.

Q: What is the difference in contact finish thickness between these parts?

A: The A-2004-2-2-LP/S-R has a contact finish thickness of 30.0µin (0.76µm), while the 5555153-1 has 50.0µin (1.27µm). Both thicknesses are within acceptable ranges for 8p8c modular connectors and do not affect functional compatibility.

Q: Does the housing material difference affect compatibility?

A: The A-2004-2-2-LP/S-R uses PBT with glass fill, while the 5555153-1 uses PBT with polyester. Both materials provide equivalent mechanical strength, environmental resistance, and thermal performance across the specified operating range of -40°C ~ 85°C. No functional impact on substitution.

Q: What packaging format is the substitute available in?

A: The 5555153-1 is supplied in Tray packaging. Verify that your assembly process accommodates tray-format components, or consult with your supplier regarding alternative packaging options if required.

Q: Are both parts MSL 1 rated?

A: Yes. Both the A-2004-2-2-LP/S-R and 5555153-1 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.

Q: Is the substitute RoHS compliant?

A: The 5555153-1 is RoHS Compliant. The original A-2004-2-2-LP/S-R does not specify RoHS status. If RoHS compliance is required for your application, the substitute meets this requirement.
