Keystone Electronics 902 RCA Jack Mono Connector - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 902 is a 3.20mm ID, 9.00mm OD (RCA) phono jack mono connector designed for through-hole, right-angle solder termination applications. This connector features a female gender configuration with 2 conductors and 2 contacts, unshielded design, and tin-plated brass contacts on a steel body. The part is currently active in production with 925 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or application-specific requirements.

Substitute Part Grouping Explanation

The CUI Devices RCJ-011 is classified as a direct substitute for the Keystone Electronics 902 based on the following critical parameters:

• Connector Type & Gender: Both are female phono (RCA) jacks
• Signal Configuration: Both support mono signal transmission
• Mating Diameter Standard: Both conform to 3.20mm ID, 9.00mm OD (RCA) industry standard
• Contact Count: Both feature 2 conductors and 2 contacts
• Mounting Configuration: Both are through-hole, right-angle designs
• Termination Method: Both use solder termination
• Shielding: Both are unshielded
• Contact & Body Materials: Both use brass contacts with tin plating and steel bodies
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

The RCJ-011 includes a board lock feature not present in the 902, and specifies an operating temperature range of -20°C to 85°C. These differences do not preclude substitution when the application requirements align with the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Keystone Electronics 902 and CUI Devices RCJ-011 meet identical electrical and mechanical requirements for RCA jack mono connector applications. Selection between these parts should be based on:

• Inventory Availability: The RCJ-011 has 2276 units in stock compared to 925 units for the 902, providing greater supply assurance
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated applications
• Operating Environment: The RCJ-011 specifies an operating temperature range of -20°C to 85°C; applications requiring operation outside this range should confirm compatibility with the 902
• Mechanical Features: The RCJ-011 includes a board lock feature; applications requiring mechanical retention should specify this part
• Packaging: The RCJ-011 is supplied in bag packaging; the 902 packaging specification is not provided

Both parts are active products with established supply chains and full regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the CUI Devices RCJ-011 be used as a direct replacement for the Keystone Electronics 902?

A: Yes. Both connectors conform to the 3.20mm ID, 9.00mm OD (RCA) industry standard, feature identical contact configurations (2 conductors, 2 contacts), and use identical termination methods (solder). Electrical and mechanical compatibility is established through matching specifications for connector type, gender, signal configuration, mounting style, and material composition.

Q: What is the difference between the board lock feature on the RCJ-011 and the 902?

A: The RCJ-011 includes a board lock feature; the 902 does not. This feature provides mechanical retention to the PCB. Applications requiring positive mechanical locking should specify the RCJ-011. Applications without this requirement can use either part.

Q: Are there operating temperature differences between these connectors?

A: The RCJ-011 specifies an operating temperature range of -20°C to 85°C. The 902 does not provide an operating temperature specification in the available data. Applications requiring operation outside the RCJ-011 range should confirm the 902 specifications with the manufacturer.

Q: Do both connectors meet the same regulatory requirements?

A: Yes. Both the Keystone Electronics 902 and CUI Devices RCJ-011 are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for restricted substances and environmental compliance.

Q: What packaging formats are available?

A: The RCJ-011 is supplied in bag packaging. The 902 packaging specification is not provided in the available documentation. Contact the manufacturer for specific packaging requirements.
