Key Parameters

Substitute Part Grouping Explanation

Substitution for the 87547-4111 is determined by strict equivalence across the following critical parameters:

• Connector type: Jack (modular)
• Contact configuration: 8p8c (RJ45/Ethernet)
• Mounting: Surface mount, vertical orientation
• Termination method: Solder
• Electrical rating: Cat3
• Contact material and finish: Phosphor bronze with gold plating
• Physical housing compatibility: Thermoplastic construction
• Environmental rating: MSL 1

The two identified substitutes maintain full electrical and mechanical compatibility with the original part across all specified parameters. Differences exist only in product status (active vs. obsolete), packaging format, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

87547-4111LF (Direct Substitute - Amphenol ICC)

This part is the direct equivalent from the original manufacturer. It maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The Cut Tape packaging format suits lower-volume procurement and prototyping workflows. This substitute is the primary choice for direct replacement in existing designs.

2-1734858-3 (MFR Recommended - TE Connectivity)

This part is the manufacturer-recommended alternative from TE Connectivity AMP Connectors. It provides full functional equivalence with active product status and RoHS compliance. The housing material differs (polyamide glass-filled vs. thermoplastic), and operating temperature is not specified by the vendor. Tape & Reel packaging is optimized for high-volume production. This substitute is suitable for new designs or high-volume applications where cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 87547-4111LF be used as a direct replacement for 87547-4111?

A: Yes. The 87547-4111LF is electrically and mechanically identical to the original part. Both are manufactured by Amphenol ICC and share the same base product number (87547). The primary differences are product status (active vs. obsolete) and packaging format (Cut Tape vs. unspecified).

Q: What is the difference between the two substitute parts?

A: Both substitutes maintain full compatibility with the original part across all critical electrical and mechanical parameters. The 87547-4111LF is from the original manufacturer (Amphenol ICC) with identical specifications. The 2-1734858-3 is from TE Connectivity with equivalent performance but different housing material composition and Tape & Reel packaging. Both are RoHS compliant and actively produced.

Q: Does housing material difference affect compatibility?

A: The housing material difference between thermoplastic (87547-4111, 87547-4111LF) and polyamide glass-filled (2-1734858-3) does not affect electrical performance or mechanical fit. Both materials meet the specified environmental and operational requirements for this connector category. Material selection depends on specific application thermal and mechanical stress requirements.

Q: What packaging formats are available?

A: The 87547-4111LF is supplied in Cut Tape (CT) format, suitable for component-level procurement and prototyping. The 2-1734858-3 is supplied in Tape & Reel (TR) format, optimized for automated assembly and high-volume production runs.

Q: Are both substitutes RoHS compliant?

A: Yes. Both the 87547-4111LF and 2-1734858-3 are RoHS compliant. The original 87547-4111 is listed as RoHS non-compliant, making either substitute necessary for applications requiring RoHS certification.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All three parts share identical pinout, contact configuration, mounting footprint, and solder termination specifications. PCB designs do not require modification when substituting between these parts.
