Amphenol ICC 98435-111 Modular Connector RJ45 Jack Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 98435-111 is a modular jack connector (8p8c RJ45, Ethernet) designed for vertical surface mount applications in Cat3 rated networks. This unshielded connector features solder termination with phosphor bronze contacts finished in gold (GXT™) and operates across an extended temperature range of -65°C to 125°C. The part is currently in active production status with 683 units available in stock.

Identifying equivalent and substitute parts becomes necessary when the primary part reaches end-of-life status, when supply constraints occur, or when design requirements shift toward improved compliance certifications such as RoHS compliance or REACH compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 98435-111 is determined by strict alignment across the following critical parameters:

• Connector Type & Configuration: Must be jack modular connector with 8-position RJ45 Ethernet configuration
• Mounting & Orientation: Surface mount vertical orientation required
• Electrical Characteristics: Unshielded, Cat3 rated, solder termination
• Material Specifications: Phosphor bronze contacts with gold finish; PCT glass-filled housing
• Environmental Ratings: Moisture sensitivity level 1 (unlimited); operating temperature compatibility

The substitute part 98435-111LF shares the core mechanical and electrical architecture with the main part but differs in specific parameters that affect application suitability and regulatory compliance status.

Engineering Selection Recommendations

Primary Selection (98435-111)

The 98435-111 remains the preferred choice for new designs and active production applications. This part maintains active product status, supports the full extended operating temperature range (-65°C to 125°C), and is currently in stock. The part is suitable for applications requiring wide thermal operating margins and legacy system compatibility.

Substitute Selection (98435-111LF)

The 98435-111LF is classified as obsolete and presents significant limitations for new designs. The restricted operating temperature range (25°C to 70°C) eliminates this part from applications requiring extended thermal performance. The contact finish thickness increase (30.0µin versus 5.00µin) and RoHS compliance status indicate this part was designed for specific regulatory environments that may not align with current design requirements.

The 98435-111LF should be considered only in scenarios where RoHS compliance is a mandatory requirement and the application operates strictly within the 25°C to 70°C temperature envelope. The obsolete status and limited inventory lifecycle make this substitute unsuitable for long-term production planning.

Frequently Asked Questions (FAQ)

Q: Can the 98435-111LF directly replace the 98435-111 in all applications?

A: No. The 98435-111LF has a restricted operating temperature range (25°C to 70°C) compared to the main part (-65°C to 125°C). Applications requiring extended thermal performance cannot use this substitute. Additionally, the 98435-111LF is classified as obsolete, limiting its availability for future production runs.

Q: What is the significance of the contact finish thickness difference?

A: The 98435-111LF features 30.0µin (0.76µm) gold finish thickness versus 5.00µin (0.127µm) on the 98435-111. This increased thickness may affect contact resistance characteristics and mechanical wear properties. The thicker finish on the obsolete part reflects design practices from an earlier production era.

Q: Does the 98435-111LF meet current regulatory requirements?

A: The 98435-111LF is RoHS compliant and REACH affected, indicating it was manufactured under stricter environmental regulations. However, its obsolete status means it is no longer actively produced or supported by the manufacturer. The 98435-111 is RoHS non-compliant, which may be relevant for specific regulatory jurisdictions or customer requirements.

Q: What is the difference between 8p8c and 8p4c configurations?

A: The 98435-111 features 8 positions with 8 contacts (8p8c), providing full RJ45 Ethernet connectivity. The 98435-111LF features 8 positions with 4 contacts (8p4c), reducing the number of active signal paths. This configuration difference may impact electrical performance and application compatibility.

Q: Are both parts suitable for Cat3 Ethernet applications?

A: Both parts carry Cat3 ratings. However, the 98435-111LF's reduced contact count (8p4c versus 8p8c) may limit its practical application in standard Ethernet implementations that require all eight contacts for proper signal transmission.

Q: What packaging considerations apply to these parts?

A: The 98435-111 is supplied in Tape & Reel (TR) packaging. The 98435-111LF packaging specification is not provided in the available data. Confirm packaging requirements with the supplier before finalizing procurement decisions.
