Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS-6488S-A-PG4-1-BA are qualified based on the following critical parameters:

• Connector type: Jack
• Contact configuration: 8p8c (RJ45, Ethernet)
• Mounting: Through hole, solder termination
• Orientation: 90° right angle
• Shielding: Shielded with EMI finger
• Contact finish: Gold plated
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: ROHS3 compliant

The identified substitutes (1-5406299-1 and 5406295-1) from TE Connectivity AMP Connectors meet these core electrical and mechanical requirements. Differences in contact material (phosphor bronze vs. copper alloy), contact finish thickness, housing material (polyamide vs. thermoplastic), and category ratings (Cat5 vs. Cat4) represent acceptable variations within the modular connector product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance. The SS-6488S-A-PG4-1-BA and its substitutes are electrically and mechanically compatible for 8p8c modular jack applications with through-hole solder termination and right-angle orientation.

Selection between the main part and substitutes depends on specific application requirements:

• The SS-6488S-A-PG4-1-BA features a board lock mechanism and copper alloy contacts with thinner gold plating (30.0µin).
• The 1-5406299-1 provides Cat5 rating with phosphor bronze contacts and thicker gold plating (50.0µin), suitable for higher-speed Ethernet applications.
• The 5406295-1 provides Cat4 rating with phosphor bronze contacts and thicker gold plating (50.0µin), suitable for standard Ethernet applications.

All parts operate across the identical temperature range (-40°C ~ 85°C) and maintain unlimited moisture sensitivity classification (MSL 1). REACH status is unaffected for all parts, with ECCN classification EAR99 and matching HTSUS codes (8536.69.4040).

Frequently Asked Questions (FAQ)

Q: Can 1-5406299-1 or 5406295-1 be used as direct replacements for SS-6488S-A-PG4-1-BA?

A: Yes, both TE Connectivity parts are electrically and mechanically compatible substitutes. All three connectors share identical contact configuration (8p8c), mounting type (through hole), orientation (90° right angle), termination method (solder), shielding (EMI finger), and operating temperature range. Differences in contact material, plating thickness, housing material, and category ratings do not prevent functional substitution in standard Ethernet applications.

Q: What is the difference between Cat4 and Cat5 ratings?

A: The 5406295-1 carries Cat4 rating, while the 1-5406299-1 carries Cat5 rating. Cat5 supports higher bandwidth and faster data transmission speeds compared to Cat4. Selection should align with the specific Ethernet standard required by the application.

Q: Are there differences in mechanical mounting between these parts?

A: The SS-6488S-A-PG4-1-BA features a board lock mechanism, while both TE Connectivity substitutes feature a board guide. Both mounting features are compatible with through-hole PCB assembly. The choice between board lock and board guide depends on application-specific mechanical retention requirements.

Q: Do all parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. All share identical HTSUS classification (8536.69.4040) and MSL 1 (unlimited) moisture sensitivity rating.

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

A: The SS-6488S-A-PG4-1-BA has 30.0µin (0.76µm) gold plating, while both TE Connectivity substitutes have 50.0µin (1.27µm) gold plating. Thicker plating provides enhanced durability and corrosion resistance, particularly beneficial in high-cycle mating applications or harsh environmental conditions.
