Key Parameters

Substitute Part Grouping Explanation

The 73305-111 has one direct substitute: 73305-111LF. This substitution is valid based on the following matching parameters:

• Connector type: Jack
• Contact configuration: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Mounting type: Surface Mount
• Orientation: 90° Angle (Right)
• Termination method: Solder
• Shielding: Unshielded
• Electrical ratings: Cat3
• Contact material: Phosphor Bronze
• Contact finish: Gold, GXT™
• Contact finish thickness: 30.0µin (0.76µm)
• Operating temperature range: -25°C ~ 70°C
• Tab direction: Up

The primary difference between these parts is packaging format and product status, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 73305-111LF is the direct functional equivalent of the 73305-111. Selection between these parts should be based on the following criteria:

Use 73305-111LF when:

• New designs or production runs require active component availability
• RoHS compliance is mandatory for the end application
• Tape & Reel packaging is compatible with assembly processes
• REACH compliance documentation is required

Use 73305-111 when:

• Existing inventory is available and cost is the primary constraint
• Legacy system maintenance requires exact original part matching
• Bulk packaging is preferred for low-volume applications

Both parts are electrically and mechanically identical in function, with differences limited to housing material composition, product lifecycle status, and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can 73305-111LF be used as a direct replacement for 73305-111?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, orientation, termination method, and operating temperature range. The primary differences are product status, packaging format, and regulatory compliance.

Q: What is the difference between the housing materials?

A: The 73305-111 uses Polyamide (PA) Nylon, while the 73305-111LF uses Polycyclohexylenedimethylene Terephthalate (PCT). Both materials are suitable for the specified operating temperature range of -25°C to 70°C and maintain the same mechanical and electrical performance.

Q: Does the packaging format affect compatibility?

A: No. The 73305-111 is supplied in bulk packaging, while the 73305-111LF is supplied in Tape & Reel format. Packaging affects handling and assembly processes but does not alter the connector's electrical or mechanical function.

Q: Is RoHS compliance a functional difference?

A: No. RoHS compliance is a regulatory certification, not a functional specification. The 73305-111LF meets RoHS requirements, while the 73305-111 does not. Selection depends on application regulatory requirements, not connector performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not have specific regulatory or packaging constraints. Both parts maintain identical pin configuration, electrical ratings, and mechanical dimensions.
