RTT8702 Equivalent & Substitute Parts

Part Overview

The RTT8702 is a 4.39mm (0.173") Phone Jack, Twin Stereo connector manufactured by Switchcraft Inc. This barrel connector features a twin stereo configuration with 3 conductors (TRS) per jack set, designed for solder termination in through-hole, right-angle mounting applications. The part is currently in active production status with 901 units available in new original inventory.

Substitute parts are identified when they maintain identical electrical and mechanical specifications, including connector type, gender, signal configuration, mating diameter, contact count, mounting orientation, and termination method. Equivalent parts ensure functional interchangeability in applications requiring this specific jack configuration.

Substitute Part Grouping Explanation

The RTT8702X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters that define functional interchangeability:

Matching Parameters:

• Connector Type: Phone Jack, Twin (identical configuration)
• Gender: Female (identical)
• Signal Configuration: Stereo (3 Conductor, TRS) (identical)
• Mating Diameter: 4.39mm (0.173") (identical)
• Number of Positions/Contacts: 2 Sets of 3 Conductors, 10 Contacts (identical)
• Mounting Type: Through Hole, Right Angle (identical)
• Termination: Solder (identical)
• Internal Switches: 2 Sets of Two Switches (identical)
• Operating Temperature Range: -55°C ~ 85°C (identical)
• Contact Material - Plating: Gold (identical)
• Housing Material: Thermoplastic (identical)
• Contact Material: Copper Alloy (identical)
• Insulation Color: Black (identical)
• RoHS Status: ROHS3 Compliant (identical)
• REACH Status: REACH Unaffected (identical)

The RTT8702X differs only in packaging (Bulk versus standard packaging) and inventory availability, with no impact on electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RTT8702 and RTT8702X are manufactured by Switchcraft Inc. and maintain active product status. Selection between these parts should be based on packaging and inventory requirements rather than electrical or mechanical performance criteria.

RTT8702 is suitable for applications requiring standard packaging configurations with current inventory of 901 units available.

RTT8702X is suitable for applications requiring bulk packaging with higher inventory availability of 1018 units. This part carries explicit ROHS3 Compliant and REACH Unaffected certifications, providing documented regulatory compliance for applications subject to these standards.

Both parts are unshielded, thermoplastic-housed connectors with gold-plated copper alloy contacts rated for -55°C to 85°C operation. Selection should prioritize packaging format and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Are RTT8702 and RTT8702X electrically interchangeable?

A: Yes. Both parts feature identical electrical specifications: twin stereo (3 conductor, TRS) configuration, 10 total contacts, gold-plated copper alloy contacts, and -55°C to 85°C operating temperature range.

Q: What is the primary difference between RTT8702 and RTT8702X?

A: The primary difference is packaging format. RTT8702X is supplied in bulk packaging, while RTT8702 uses standard packaging. No electrical or mechanical differences exist between the parts.

Q: Can RTT8702X be used in place of RTT8702 in existing designs?

A: Yes. The RTT8702X maintains identical connector type, gender, signal configuration, mating diameter, contact count, mounting orientation, and termination method. Direct substitution is functionally equivalent.

Q: What does the "Twin Stereo" configuration mean?

A: Twin Stereo indicates two independent stereo (TRS) jack sets in a single connector body. Each set contains 3 conductors (Tip, Ring, Sleeve), totaling 10 contacts across both sets with 2 sets of two internal switches.

Q: Are both parts RoHS and REACH compliant?

A: RTT8702X explicitly carries ROHS3 Compliant and REACH Unaffected certifications. RTT8702 compliance status is not specified in available documentation. For applications requiring documented regulatory compliance, RTT8702X is the specified choice.

Q: What is the mating diameter tolerance?

A: The industry recognized mating diameter is 4.39mm (0.173"). RTT8702X specifies an actual diameter of 0.177" (4.48mm), representing the physical jack opening dimension.

Q: What mounting configuration do these connectors use?

A: Both parts use through-hole, right-angle mounting with solder termination. The right-angle orientation positions the connector perpendicular to the PCB surface.
