TE Connectivity 8-2120875-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 8-2120875-1 is a modular coupler connector jack designed for RJ45 8p8c (8-position 8-contact) applications rated to Cat5e specifications. This component functions as a jack-to-jack coupler with a 180-degree configuration and panel mount square flange mounting type. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system maintenance and new design implementations where Cat5e or higher-rated alternatives are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8-2120875-1 is determined by the following critical parameters that must remain consistent or be upgraded:

Mandatory Compatibility Parameters:

• Connector interface: Jack 8p8c (RJ45) to Jack 8p8c (RJ45) configuration
• Mounting interface: Panel mount installation capability
• Electrical rating: Cat5e minimum (Cat6a represents an upgrade path)
• Compliance: RoHS Compliant status

Substitution Logic: The identified substitute part 1-2120871-1 maintains the core jack-to-jack 8p8c (RJ45) interface and panel mount capability. The substitute represents a functional upgrade, offering Cat6a rating (higher bandwidth capability than Cat5e) with shielded construction and IP67 ingress protection. Both parts share RoHS compliance and EAR99 export classification. The transition from coupler type to adapter type with mounting hardware does not affect the electrical substitution relationship for jack-to-jack coupling applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The 1-2120871-1 substitute part provides functional equivalence for jack-to-jack RJ45 8p8c coupling applications. Both the main part and substitute maintain RoHS compliance and EAR99 export classification, ensuring regulatory consistency.

Upgrade Considerations: The substitute part 1-2120871-1 offers enhanced electrical performance through Cat6a rating compared to the Cat5e specification of the main part. The addition of shielding and IP67 ingress protection in the substitute provides environmental robustness suitable for applications requiring dust and moisture resistance.

Obsolescence Status: Both the main part 8-2120875-1 and substitute part 1-2120871-1 are classified as obsolete. Component selection should prioritize current-production alternatives where available for new designs or long-term system support requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1-2120871-1 directly replace the 8-2120875-1 in existing installations?

A: Yes. Both parts maintain the jack-to-jack 8p8c (RJ45) interface and panel mount capability. The substitute operates at Cat6a rating, which is backward compatible with Cat5e systems. The addition of shielding and IP67 protection in the substitute does not prevent functional substitution.

Q: What is the difference between the coupler and adapter designations?

A: The main part 8-2120875-1 is classified as a coupler type, while the substitute 1-2120871-1 is classified as an adapter type. Both perform jack-to-jack coupling functions. The adapter designation in the substitute reflects the inclusion of mounting hardware features.

Q: Are there electrical performance differences between Cat5e and Cat6a ratings?

A: Cat6a represents a higher bandwidth specification than Cat5e. The substitute part 1-2120871-1 with Cat6a rating supports greater data transmission capacity. Cat6a connectors are compatible with Cat5e systems and networks.

Q: Does the shielding in the substitute part affect compatibility?

A: No. Shielded connectors are compatible with unshielded systems. The shielding in the 1-2120871-1 provides additional electromagnetic interference protection without compromising mechanical or electrical compatibility with standard RJ45 jack interfaces.

Q: What does IP67 ingress protection mean for this connector?

A: IP67 rating indicates the connector is dust tight and can withstand temporary immersion in water. This environmental protection is an enhancement over the main part and does not affect compatibility with standard panel mount installations.

Q: Are both parts RoHS compliant?

A: Yes. Both the 8-2120875-1 and 1-2120871-1 are RoHS compliant, ensuring compliance with hazardous substance restrictions in manufacturing and end-of-life disposal.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these parts are no longer in active production by the manufacturer. Current-production modular connector alternatives should be evaluated for new system designs or long-term component availability requirements.
