Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RTTC8705 are identified based on strict electrical and mechanical parameter alignment. The critical substitution criteria are:

• Connector Type: Phone Jack, Twin configuration
• Gender: Female jack
• Signal Configuration: Stereo (3 Conductor, TRS)
• Mating Diameter: 4.39mm (0.173") industry standard
• Contact Count: 2 Sets of 3 Conductors, 10 Contacts total
• Mounting: Through Hole, Right Angle orientation
• Termination Method: Solder
• Operating Temperature Range: -55°C ~ 85°C
• Contact Plating: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

Parts meeting all these parameters are considered direct substitutes and are electrically and mechanically interchangeable in applications designed for the RTTC8705.

Parameter Comparison

Engineering Selection Recommendations

The RTT8705X is a direct substitute for the RTTC8705 based on matching electrical and mechanical specifications. Both parts are manufactured by Switchcraft Inc. and share identical connector type, gender, signal configuration, mating diameter, contact count, mounting orientation, and termination method.

The RTT8705X carries Active product status and is ROHS3 compliant with REACH Unaffected certification, confirming regulatory compliance for current applications. The part maintains the same operating temperature range (-55°C ~ 85°C) and gold-plated copper alloy contacts with thermoplastic housing.

Selection between RTTC8705 and RTT8705X should be based on availability, lead time requirements, and inventory management priorities. Both parts are suitable for direct substitution in applications requiring 4.39mm twin stereo phone jack connectors with solder termination.

Frequently Asked Questions (FAQ)

Q: Are RTTC8705 and RTT8705X electrically interchangeable?

A: Yes. Both parts feature identical signal configuration (Stereo 3-Conductor TRS), contact count (10 total contacts in 2 sets of 3 conductors), mating diameter (4.39mm), and operating temperature range (-55°C ~ 85°C). They are electrically interchangeable in applications designed for either part number.

Q: Are these parts mechanically compatible?

A: Yes. Both parts share identical mounting type (Through Hole, Right Angle), termination method (Solder), and housing material (Thermoplastic). Mechanical compatibility is confirmed for PCB integration and panel mounting applications.

Q: What is the difference between RTTC8705 and RTT8705X?

A: The primary difference is the series designation (RTTC versus RTT). The RTT8705X includes documented internal switch configuration (2 Sets of Two Switches) and specifies actual diameter tolerance (0.177" / 4.48mm) versus the industry standard mating diameter (4.39mm / 0.173"). Both parts meet the same functional and compliance requirements.

Q: Are both parts RoHS compliant?

A: The RTT8705X is explicitly ROHS3 compliant. Compliance status for the RTTC8705 is not specified in available documentation. For applications requiring RoHS certification, the RTT8705X provides documented compliance.

Q: What is the moisture sensitivity level for these connectors?

A: The RTT8705X has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling do not require controlled humidity environments.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that application requirements do not specify a particular part number. Both parts meet identical electrical and mechanical specifications for 4.39mm twin stereo phone jack connectors with solder termination. Substitution should follow standard engineering change control procedures.
