Substitute Part Grouping Explanation

Substitution of the obsolete SS-718808S-A-PG4-AC is based on strict alignment of the following critical parameters:

• Connector type: Jack modular connector
• Contact configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° angle right-hand
• Termination method: Solder
• Shielding: Shielded with EMI finger
• Electrical rating: Cat5e
• Contact material and finish: Copper alloy with gold plating
• Housing material: Thermoplastic
• Compliance: ROHS3 and REACH requirements

The substitute part SS71800-095F maintains all critical electrical and mechanical parameters required for functional equivalence. Both parts belong to the Stewart Connector Series 71 modular connector family and share identical contact configurations, shielding architecture, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

The SS71800-095F is the manufacturer-recommended substitute for the obsolete SS-718808S-A-PG4-AC. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The substitute part is currently in active production status with confirmed inventory availability (1134 pcs), providing supply chain security for new designs and field replacements.

The primary difference between the main part and substitute is the contact finish thickness, where SS71800-095F provides 50.0µin (1.27µm) compared to 30.0µin (0.76µm) on the original part. This increased gold plating thickness on the substitute enhances contact durability and corrosion resistance without affecting electrical performance or mechanical compatibility.

The SS71800-095F supports both panel mount and through-hole mounting configurations, providing additional design flexibility compared to the through-hole-only mounting of the original part. For applications requiring through-hole solder termination with 90° right-angle orientation and Cat5e shielded performance, the SS71800-095F delivers full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can SS71800-095F be used as a direct replacement for SS-718808S-A-PG4-AC in existing PCB designs?

A: Yes. Both connectors share identical contact configurations (8p8c RJ45), orientation (90° right-angle), termination method (solder), shielding architecture (EMI finger), and electrical ratings (Cat5e). Through-hole mounting compatibility is maintained, allowing direct substitution in existing board layouts.

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

A: The SS71800-095F features 50.0µin (1.27µm) gold plating versus 30.0µin (0.76µm) on the original part. The increased thickness provides enhanced contact durability, improved corrosion resistance, and extended mating cycle life without altering electrical performance or mechanical fit.

Q: Does the substitute part's panel mount capability affect through-hole applications?

A: No. The SS71800-095F supports both panel mount and through-hole mounting configurations. For through-hole solder applications, the connector functions identically to the original part. The additional panel mount capability provides design flexibility for future applications without compromising existing through-hole implementations.

Q: Are there compliance or certification differences between the two parts?

A: Both parts maintain identical compliance status: ROHS3 compliant and REACH unaffected. No regulatory or certification differences exist between the main part and substitute.

Q: What is the inventory status for the substitute part?

A: SS71800-095F is in active production with 1134 pcs confirmed in stock as new original inventory, ensuring reliable supply chain availability for production and field replacement requirements.
