• Connector type (Jack)
• Contact configuration (6p4c RJ11/RJ14)
• Port count (2)
• Orientation (90° right angle)
• Mounting method (through hole)
• Termination type (solder)
• Shielding architecture (shielded with EMI finger)
• Contact material and finish (copper alloy with gold plating)
• Housing material (thermoplastic)
• Tab orientation (down)

The substitute part SS-664602S-A-PG4-AC-50 maintains all these critical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SS-664602S-A-PG4-AC-50 is the direct substitute for the obsolete SS-664602S-A-PG4-AC. The substitute maintains functional and mechanical equivalence across all critical connector parameters while providing the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance certification for regulatory alignment
• Specified operating temperature range (-40°C ~ 85°C) for thermal performance documentation
• Increased contact finish thickness (50.0µin versus 30.0µin) provides enhanced durability and contact reliability

Both parts share identical REACH unaffected status and moisture sensitivity classification. The substitute part is suitable for direct replacement in applications currently utilizing the main part number.

Frequently Asked Questions (FAQ)

Q: Can SS-664602S-A-PG4-AC-50 be used as a direct replacement for SS-664602S-A-PG4-AC?

A: Yes. Both connectors maintain identical specifications for connector type, contact configuration (6p4c RJ11/RJ14), port count, orientation, mounting method, termination type, shielding, contact material, housing material, and tab direction. The substitute is functionally and mechanically equivalent.

Q: What is the difference in contact finish thickness between these parts?

A: The main part features 30.0µin (0.76µm) gold plating, while the substitute provides 50.0µin (1.27µm) gold plating. The increased thickness in the substitute part enhances contact durability and wear resistance.

Q: Why is the main part classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The substitute part SS-664602S-A-PG4-AC-50 maintains the same functional design while offering active product status and current compliance certifications.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified. The substitute part is supplied in tray packaging, which is standard for modular connector distribution.

Q: Do both parts meet the same regulatory requirements?

A: Both parts share REACH unaffected status and MSL 1 (unlimited) moisture sensitivity classification. The substitute additionally provides ROHS3 compliance certification and documented operating temperature specifications.

Q: What is the base product number for these connectors?

A: The base product number is SS-664602, which identifies the core connector design family within the Stewart Connector 66 series.
