TE Connectivity AMP Connectors 554990-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 554990-1 is a modular jack connector with 6 positions and 6 contacts (6p6c), supporting RJ11, RJ12, RJ14, and RJ25 configurations. This vertical unshielded connector is designed for through-hole solder termination in Cat3 applications. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and design continuity. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 554990-1 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the 5554990-1, which maintains complete parameter alignment with the original part across connector type, contact configuration, mounting methodology, orientation, termination approach, shielding classification, category rating, contact materials, finish specifications, housing composition, and operating temperature range.

The substitution logic is based on the following critical parameters that must remain identical:

• Connector type classification (Jack)
• Contact configuration (6p6c with RJ11, RJ12, RJ14, RJ25 compatibility)
• Through-hole mounting requirement
• Vertical orientation
• Solder termination capability
• Unshielded design
• Cat3 electrical rating
• Phosphor bronze contact material with gold finish at specified thickness
• PBT polyester housing material
• Operating temperature envelope (-40°C to 85°C)
• Mechanical features (Board Lock, Offset Latch, Panel Stops)
• User-selectable tab direction

Parameter Comparison

Engineering Selection Recommendations

The 5554990-1 serves as the direct functional equivalent to the obsolete 554990-1. All electrical and mechanical parameters are identical, ensuring complete interchangeability at the circuit and board level.

The primary distinction between these parts is product lifecycle status. The 554990-1 is classified as obsolete, while the 5554990-1 maintains active product status with current manufacturing support. This status difference is significant for long-term supply chain planning and component availability.

Compliance differences exist between the two parts. The 554990-1 is RoHS non-compliant, whereas the 5554990-1 achieves ROHS3 compliance. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 5554990-1 is the appropriate selection. The 5554990-1 also specifies tray packaging, whereas the original part packaging is not detailed.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 5554990-1 be used as a direct replacement for the 554990-1 in existing designs?

A: Yes. The 5554990-1 maintains complete electrical and mechanical equivalence to the 554990-1 across all specified parameters. No circuit redesign or board layout modification is required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturing and supply availability. The 554990-1 is obsolete and subject to limited or discontinued production. The 5554990-1 is active and maintains current manufacturing support, ensuring reliable long-term procurement.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulatory adherence, not electrical or mechanical function. Both parts perform identically in circuit applications. RoHS compliance becomes relevant only when regulatory requirements or customer specifications mandate it.

Q: Are there packaging considerations when substituting these parts?

A: The 5554990-1 is supplied in tray packaging. If the original procurement specified different packaging, verify that tray packaging is compatible with your receiving, storage, and assembly processes.

Q: What are the key parameters that must remain identical for substitution?

A: Substitution requires equivalence in connector type (Jack), contact configuration (6p6c RJ11/RJ12/RJ14/RJ25), mounting method (through-hole), orientation (vertical), termination (solder), shielding (unshielded), category rating (Cat3), contact material (phosphor bronze with gold finish), housing material (PBT polyester), operating temperature range (-40°C to 85°C), and mechanical features (board lock, offset latch, panel stops).

Q: Can these connectors be used interchangeably with other RJ-series connectors?

A: These 6p6c connectors are compatible with RJ11, RJ12, RJ14, and RJ25 standards as specified. Compatibility with other RJ-series configurations is not supported by the provided specifications.

Q: What is the operating temperature range for both parts?

A: Both the 554990-1 and 5554990-1 operate across the temperature range of -40°C to 85°C.

Q: Are there any differences in contact finish specifications?

A: No. Both parts feature phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness, ensuring identical electrical contact characteristics and corrosion resistance.
