Substitute Part Grouping Explanation

Substitution eligibility for the SS-6488S-A-PG4-BA-50 is determined by strict alignment of the following critical parameters:

• Connector type: Jack
• Contact configuration: 8p8c (RJ45, Ethernet)
• Port and row count: 1 port, 1 row
• Mounting method: Through hole
• Orientation: 90° right angle
• Termination method: Solder
• Shielding configuration: Shielded with EMI finger
• Contact finish: Gold plating at 50.0µin (1.27µm)
• Operating temperature range: -40°C to 85°C
• Regulatory compliance: ROHS3 compliant

The substitute part 1-5406299-1 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters required for direct substitution. Both connectors maintain identical contact configuration, mounting specifications, termination method, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-6488S-A-PG4-BA-50 and 1-5406299-1 are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability and lead time requirements
• Inventory levels (SS-6488S-A-PG4-BA-50: 1092 pcs; 1-5406299-1: 5539 pcs)
• Specific mechanical feature requirements (board lock vs. board guide)
• Contact material preference (copper alloy vs. phosphor bronze)
• Housing material specification (thermoplastic vs. polyamide/nylon)

Both connectors satisfy identical electrical performance requirements and environmental operating conditions. The substitute part carries higher inventory availability and Cat5 rating specification.

Frequently Asked Questions (FAQ)

Q: Can 1-5406299-1 be used as a direct replacement for SS-6488S-A-PG4-BA-50?

A: Yes. Both connectors share identical contact configuration (8p8c RJ45), mounting type (through hole), orientation (90° right angle), termination method (solder), shielding (EMI finger), contact finish (gold at 50.0µin), and operating temperature range (-40°C to 85°C). Both are ROHS3 compliant and REACH unaffected.

Q: What are the differences between these two connectors?

A: The primary differences are contact material (copper alloy vs. phosphor bronze), housing material (thermoplastic vs. polyamide/nylon), and mechanical features (board lock vs. board guide). These differences do not affect electrical compatibility or functional performance in standard 8p8c applications.

Q: Are there any compatibility concerns with PCB footprints?

A: Both connectors use identical through-hole mounting specifications and 90° right-angle orientation. PCB footprints designed for either connector are compatible with both parts.

Q: What is the significance of the Cat5 rating on the TE Connectivity part?

A: The Cat5 rating on 1-5406299-1 indicates compliance with Category 5 Ethernet standards. This specification is provided in the substitute part documentation and does not restrict its use in applications requiring standard 8p8c modular jack functionality.

Q: How should I select between these two parts for new designs?

A: Selection should be based on availability, lead time, inventory levels, and any specific mechanical feature requirements. Both parts meet identical electrical and environmental specifications for 8p8c modular jack applications.
