Keystone Electronics 565 RCA Phono Plug Mono Connector

Part Overview

The Keystone Electronics 565 is a Phono (RCA) plug mono connector with 2 conductors and 2 contacts, designed for solder termination in free-hanging (in-line) applications. The connector features a 3.20mm ID and 9.00mm OD mating diameter, standard for RCA phono connectors. This part is currently obsolete, making equivalent substitutes necessary for ongoing design and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Keystone Electronics 565 is based on strict electrical and mechanical compatibility criteria. All substitute parts must meet the following requirements:

• Connector Type: Phono (RCA) Plug
• Gender: Male
• Signal Lines: Mono
• Mating Diameter: 3.20mm ID, 9.00mm OD (RCA standard)
• Number of Contacts: 2 Conductors, 2 Contacts
• Mounting Type: Free Hanging (In-Line)
• Termination: Solder
• Shielding: Unshielded
• RoHS Compliance: ROHS3 Compliant

Two active substitute parts meet these criteria: Switchcraft Inc. 3501MX and Switchcraft Inc. 35582X. Both are manufactured by Switchcraft Inc., a recognized supplier of RCA connectors, and maintain full compatibility with the original Keystone 565 specification for mating interface and electrical function.

Parameter Comparison

Engineering Selection Recommendations

Both Switchcraft substitutes are active products with ROHS3 compliance and REACH unaffected status, providing regulatory continuity with the obsolete Keystone 565.

Switchcraft 3501MX is the closest dimensional match, with a mating length of 0.560" (14.20mm) compared to the original 0.562" (14.27mm). This part maintains nickel plating on contacts and is supplied in bulk packaging.

Switchcraft 35582X offers enhanced specifications including rated voltage (250VAC, 140VDC) and current rating (6A), with mounting hardware included. The mating length is 0.640" (16.30mm), representing a 0.078" increase. This part is available in silver and black body colors and includes thermoplastic housing material.

Selection between these two substitutes depends on application requirements: choose 3501MX for dimensional consistency with the original design, or 35582X for applications requiring specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Are the Switchcraft substitutes mechanically compatible with the Keystone 565?

A: Both Switchcraft parts maintain the standard RCA phono connector mating interface (3.20mm ID, 9.00mm OD) and free-hanging solder termination configuration. Mating length variations (3501MX at 14.20mm, 35582X at 16.30mm versus original 14.27mm) are within typical RCA connector tolerance ranges and do not affect mating compatibility.

Q: What is the difference between the two Switchcraft substitutes?

A: The 3501MX provides the closest dimensional match to the original part. The 35582X includes rated electrical specifications (250VAC, 140VDC, 6A), operating temperature range (-40°C to 85°C), mounting hardware, and thermoplastic housing, making it suitable for applications requiring specified electrical performance and environmental ratings.

Q: Are both substitutes RoHS compliant?

A: Yes, both Switchcraft 3501MX and 35582X are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original Keystone 565.

Q: What packaging is available for these substitutes?

A: Switchcraft 3501MX is supplied in bulk packaging. Switchcraft 35582X is also supplied in bulk packaging and includes 2 pieces per connector (1 connector, 1 handle).
