TE Connectivity AMP Connectors 1546877-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1546877-1 is a modular jack connector with 8 positions and 8 contacts (8p8c/RJ45) designed for Ethernet applications. This unshielded Cat5e connector features panel mount installation with a straight orientation and IDC color-coded block termination. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and component sourcing.

The obsolete status of the 1546877-1 necessitates evaluation of active alternative components that maintain compatibility with existing installations while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the 1546877-1 is based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector type and contact configuration (8p8c/RJ45)
• Electrical ratings (Cat5e)
• Operating temperature range (-55°C ~ 105°C)
• Ingress protection level (IP67)
• RoHS compliance and MSL classification
• Series designation (CPC 45)

Substitution Logic:

The 1546877-1 is a jack connector with unshielded construction. The identified substitute part, 1986172-1, is a modular coupler connector that converts jack 8p8c to jack 8p8c connections. While both components operate within the same electrical rating (Cat5e), series (CPC 45), temperature range, and ingress protection specification, they serve different functional roles in modular connector applications.

The 1986172-1 coupler provides an adapter function rather than direct replacement functionality. This component is suitable for applications requiring connection between two 8p8c jack connectors, whereas the 1546877-1 functions as a standalone jack connector for panel mount installation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The 1546877-1 is an obsolete component. Direct replacement with an equivalent jack connector from the active CPC 45 series should be prioritized for new designs and system upgrades. The substitute part 1986172-1 does not function as a direct replacement due to its coupler configuration.

For Adapter and Extension Applications:

The 1986172-1 coupler connector is suitable for applications requiring connection between two 8p8c jack connectors. This component maintains compatibility with the Cat5e electrical rating and operating temperature specifications of the 1546877-1. The shielded construction of the 1986172-1 provides enhanced electromagnetic interference protection compared to the unshielded 1546877-1.

Compliance Considerations:

Both components are RoHS compliant with MSL classification of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. Both components carry ECCN classification EAR99, meeting export control requirements.

Availability:

The 1986172-1 demonstrates significantly higher inventory availability (64,420 pieces) compared to the 1546877-1 (650 pieces), supporting long-term sourcing reliability for active production environments.

Frequently Asked Questions (FAQ)

Q: Can the 1986172-1 coupler directly replace the 1546877-1 jack connector?

A: No. The 1986172-1 is a coupler connector designed to connect two 8p8c jack connectors, whereas the 1546877-1 is a standalone jack connector for panel mount installation. These components serve different functional roles and are not direct replacements.

Q: What are the key electrical compatibility factors between these components?

A: Both components operate at Cat5e ratings, support 8p8c (RJ45) contact configurations, and function within the same operating temperature range (-55°C ~ 105°C). Both maintain IP67 ingress protection and RoHS compliance.

Q: Does the shielded construction of the 1986172-1 affect compatibility with the unshielded 1546877-1?

A: The shielding difference reflects different design approaches. The 1546877-1 is unshielded, while the 1986172-1 is shielded. In applications where both components are used within the same system, the shielded coupler provides additional electromagnetic interference protection without compromising electrical compatibility at Cat5e ratings.

Q: Are there packaging differences between these components?

A: The 1546877-1 packaging specification is not provided in the available data. The 1986172-1 is supplied in bag packaging. Packaging differences do not affect functional compatibility but may influence handling and storage procedures.

Q: What is the significance of the CPC 45 series designation?

A: The CPC 45 series designation indicates both components belong to the same TE Connectivity AMP Connectors product family, ensuring mechanical and electrical compatibility within this series for modular connector applications.

Q: How does the obsolete status of the 1546877-1 affect component selection?

A: The obsolete status indicates the 1546877-1 is no longer in active production. For new installations and system upgrades, selection should prioritize active components from the CPC 45 series. The 1986172-1 remains in active production status, supporting long-term availability for maintenance and repair applications.

Q: Are both components suitable for the same environmental conditions?

A: Yes. Both components maintain IP67 ingress protection (dust tight, waterproof) and operate across the identical temperature range (-55°C ~ 105°C), supporting deployment in equivalent environmental conditions.
