Amphenol ICC 73306-111 Modular Connector: Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 73306-111 is a modular jack connector designed for telecommunications and data communication applications. This component is classified as a modular connector (RJ-series) and is currently in active product status. The 73306-111 is a through-hole, straight-orientation jack connector with 4 positions and 4 contacts (4p4c configuration).

Finding equivalent and substitute parts becomes necessary when the original configuration is unavailable, when specific packaging requirements must be met, or when design modifications require alternative mounting orientations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 73306-111LF is derived from the same base product family (73306) and maintains compatibility through the following critical parameters:

Electrical Compatibility:

• Contact configuration: 4 positions, 4 contacts (4p4c / RJ9, RJ10, RJ22 standard)
• Contact material and finish specifications remain consistent
• Unshielded design classification

Mechanical Compatibility:

• Same connector type classification (Jack Modular Connector)
• Single port, single row configuration
• Solder termination method
• Operating temperature range: -25°C to 70°C

Regulatory Alignment:

• Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications
• Both maintain MSL 1 (Unlimited) moisture sensitivity rating

Primary Differentiation: The 73306-111LF differs in mounting orientation (90° right angle versus straight) and packaging format (Cut Tape & Digi-Reel versus bulk), making it suitable for applications requiring surface-mount right-angle installation while maintaining the same electrical interface.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Compliance Requirements: The 73306-111LF is the appropriate selection when RoHS compliance is mandated. This substitute part meets RoHS standards while maintaining identical electrical interface specifications and regulatory classifications (ECCN, HTSUS).

For Mounting Orientation Constraints: Applications requiring right-angle surface-mount installation should specify the 73306-111LF. The 90° orientation and surface-mount configuration provide mechanical advantages in space-constrained PCB layouts while preserving the 4p4c contact interface.

For Packaging and Supply Chain Considerations: The 73306-111LF is available in Cut Tape and Digi-Reel packaging formats, supporting automated assembly processes. The main part 73306-111 is available in bulk packaging, suitable for manual assembly or custom packaging requirements.

For Active Product Status: Both parts maintain active product status with Amphenol ICC, ensuring continued availability and support for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the 73306-111LF be used as a direct replacement for the 73306-111 in existing designs?

A: Electrical compatibility is maintained through identical 4p4c contact configuration and unshielded design. However, the 73306-111LF features 90° right-angle orientation and surface-mount mounting, whereas the 73306-111 is straight-orientation through-hole. PCB layout and mechanical clearance must be re-evaluated before substitution.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 73306-111 is RoHS non-compliant, while the 73306-111LF is RoHS compliant. For applications subject to RoHS regulations or customer requirements, the 73306-111LF must be specified. Both parts share identical ECCN and HTSUS classifications.

Q: Are the contact specifications identical between the two parts?

A: Both parts use Phosphor Bronze contacts with Gold GXT™ finish. The 73306-111LF specifies contact finish thickness at 30.0µin (0.76µm). Contact material and finish type ensure equivalent electrical performance and signal integrity for 4p4c modular connector applications.

Q: What packaging formats are available for each part?

A: The 73306-111 is supplied in bulk packaging. The 73306-111LF is available in Cut Tape (CT) and Digi-Reel® formats, supporting high-volume automated assembly operations.

Q: Do both parts share the same operating temperature range?

A: The 73306-111LF specifies operating temperature range of -25°C to 70°C. The 73306-111 operating temperature is not specified in the provided data. For applications with defined temperature requirements, the 73306-111LF provides documented thermal specifications.

Q: Are there any differences in moisture sensitivity or environmental ratings?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions for storage or handling. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.
