Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MODS-E-8P8C-L-S is determined by the following critical parameters:

Primary Substitution Criteria:

• Connector Type: Jack
• Number of Positions/Contacts: 8P8C (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: Vertical
• Termination: Solder
• Shielding: Shielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold

Secondary Compatibility Parameters:

• Number of Ports: 1
• Number of Rows: 1
• Features: Board Lock
• Tab Direction: User Selectable
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

Substitute parts are grouped into two categories based on electrical ratings and housing material composition:

Category A - Cat3 Rated Shielded Connectors: Parts 3-1734577-2, 3-1734577-4, A-2014-2S-1-N, A-2014-2S-2-N, and A-2014-2S-3-N maintain Cat3 electrical ratings with shielded configurations. These parts differ in contact finish thickness and housing material composition but preserve the core electrical and mechanical interface.

Category B - Enhanced Shielding Configuration: Part 5557969-1 provides shielded configuration with EMI finger enhancement and Cat3 ratings, offering additional electromagnetic interference protection.

Category C - Unshielded Alternative: Part A00-108-620-450 provides an unshielded 8P8C connector with Cat5 ratings. This part is listed as a substitute but operates without shielding, requiring evaluation of application EMI requirements.

Category D - Cat5 Rated Shielded Connector: Part SS-71100-005 provides shielded configuration with Cat5 ratings, offering enhanced bandwidth capability compared to the original Cat3 specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

Parts 3-1734577-2 and 3-1734577-4 from TE Connectivity AMP Connectors are active products with identical mechanical and electrical interfaces to the MODS-E-8P8C-L-S. Both maintain 8P8C vertical shielded configuration with Cat3 ratings, through-hole solder termination, and phosphor bronze gold-plated contacts. Part 3-1734577-4 provides increased contact finish thickness (50.0µin versus 15.0µin), offering enhanced durability. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating.

Secondary Substitutes (Assmann WSW Components):

Parts A-2014-2S-1-N, A-2014-2S-2-N, and A-2014-2S-3-N from Assmann WSW Components provide shielded 8P8C vertical connectors with identical mechanical interfaces. These parts differ in contact finish thickness (15.0µin, 30.0µin, and 50.0µin respectively) and housing material composition (polyester versus PBT glass-filled). All three are ROHS3 compliant with operating temperature range of -40°C to 85°C, which encompasses the original -25°C to 90°C specification. Electrical ratings are not specified for these parts.

Enhanced Shielding Option:

Part 5557969-1 from TE Connectivity AMP Connectors provides shielded configuration with EMI finger enhancement and Cat3 ratings. This part offers additional electromagnetic interference protection through EMI finger design and panel stops feature. Operating temperature range is -40°C to 85°C. RoHS compliance is confirmed; REACH status is unaffected.

Alternative Configurations:

Part A00-108-620-450 from Mercury United Electronics provides unshielded 8P8C configuration with Cat5 ratings. This part eliminates shielding, which may be unsuitable for applications requiring EMI protection. Cat5 rating provides enhanced bandwidth capability.

Part SS-71100-005 from Stewart Connector provides shielded 8P8C configuration with Cat5 ratings and copper alloy contacts. This part offers bandwidth enhancement over Cat3 specification with maintained shielding. Operating temperature range is -40°C to 85°C.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and EAR99 ECCN classification. REACH status varies across manufacturers; TE Connectivity and Stewart Connector parts are REACH unaffected, while Assmann WSW components are REACH unaffected. Mercury United Electronics part is REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can I use part 3-1734577-4 as a direct replacement for MODS-E-8P8C-L-S?

A: Yes. Part 3-1734577-4 maintains identical connector type, position count, mounting method, orientation, termination, shielding, and Cat3 ratings. The primary difference is increased contact finish thickness (50.0µin versus 15.0µin), which provides enhanced contact durability without affecting electrical or mechanical compatibility.

Q: What is the difference between the Assmann WSW parts A-2014-2S-1-N, A-2014-2S-2-N, and A-2014-2S-3-N?

A: These three parts differ only in contact finish thickness: A-2014-2S-1-N provides 15.0µin, A-2014-2S-2-N provides 30.0µin, and A-2014-2S-3-N provides 50.0µin. All three maintain identical mechanical interfaces, shielding, and through-hole solder termination. Selection depends on application durability requirements and contact wear expectations.

Q: Why is part A00-108-620-450 listed as a substitute if it is unshielded?

A: Part A00-108-620-450 is listed as a substitute based on the provided input data. However, this part eliminates shielding present in the original MODS-E-8P8C-L-S. Applications requiring electromagnetic interference protection should not use this unshielded alternative. Verify application EMI requirements before selection.

Q: Does part 5557969-1 provide better performance than the original MODS-E-8P8C-L-S?

A: Part 5557969-1 maintains Cat3 ratings identical to the original part. The EMI finger enhancement provides additional electromagnetic interference protection through improved shielding design. Panel stops feature provides mechanical positioning benefit. Operating temperature range is -40°C to 85°C, which is narrower than the original -25°C to 90°C specification.

Q: Can I use Cat5 rated parts SS-71100-005 or A00-108-620-450 in place of the Cat3 rated original?

A: Cat5 rated parts provide enhanced bandwidth capability and are backward compatible with Cat3 applications. Part SS-71100-005 maintains shielding and is suitable for direct substitution. Part A00-108-620-450 eliminates shielding and requires application EMI evaluation before use.

Q: What packaging formats are available for substitute parts?

A: TE Connectivity parts (3-1734577-2, 3-1734577-4, 5557969-1) are supplied in Tray packaging. Assmann WSW parts (A-2014-2S-1-N, A-2014-2S-2-N, A-2014-2S-3-N) are supplied in Tray packaging. Mercury United Electronics part (A00-108-620-450) is supplied in Bulk packaging. Stewart Connector part (SS-71100-005) packaging is not specified in available data.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant or RoHS compliant. Verify specific compliance requirements for your application and regulatory jurisdiction before final selection.
