3514PCX RCA Phono Jack Mono Connector - Equivalent & Substitute Parts

Part Overview

The 3514PCX is a 3.2mm ID, 9.0mm OD RCA phono jack mono connector manufactured by Switchcraft Inc., designed for through-hole PCB mounting with solder termination. This connector features 2 conductors and 2 contacts in an unshielded configuration with tin-plated brass contacts and steel body construction.

The 3514PCX is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for applications utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3514PCX is determined by strict alignment with the following critical parameters:

• Connector Type & Gender: Must be Phono (RCA) Jack, Female configuration
• Signal Configuration: Must support Mono signal lines
• Mating Diameter: Must conform to 3.20mm ID, 9.00mm OD (RCA) standard
• Contact Count: Must provide 2 Conductors, 2 Contacts
• Mounting & Termination: Must support Through Hole mounting with Solder termination
• Shielding: Must be Unshielded
• Contact Material: Must be Brass
• Regulatory Compliance: Must maintain ROHS3 Compliant status

The RCJ-021 manufactured by CUI Devices meets all substitution criteria. This part maintains identical connector type, gender, signal configuration, contact count, mounting method, termination type, shielding, and contact material specifications. Both parts are ROHS3 compliant and carry the same HTSUS classification.

Parameter Comparison

Engineering Selection Recommendations

The RCJ-021 is the qualified substitute for the 3514PCX. Both connectors maintain identical electrical and mechanical specifications across all critical parameters. The RCJ-021 offers the advantage of active product status with current manufacturing support and significantly higher inventory availability (39,041 units in stock versus 1,082 units for the obsolete 3514PCX).

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support. The RCJ-021 includes board lock features and operates across the -20°C to 85°C temperature range, providing enhanced mechanical retention and defined thermal performance parameters.

Frequently Asked Questions (FAQ)

Q: Can the RCJ-021 directly replace the 3514PCX in existing PCB designs?

A: Yes. Both connectors share identical mating diameter (3.20mm ID, 9.00mm OD), contact count (2 Conductors, 2 Contacts), mounting type (Through Hole), and termination method (Solder). PCB footprints designed for the 3514PCX are compatible with the RCJ-021.

Q: What are the key differences between these two parts?

A: The primary differences are product status (3514PCX is obsolete; RCJ-021 is active), contact plating (3514PCX uses tin; RCJ-021 uses nickel), body material (3514PCX uses steel; RCJ-021 uses brass), and additional features (RCJ-021 includes board lock). Both maintain identical connector type, gender, signal configuration, and mounting specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3514PCX and RCJ-021 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging is available for the RCJ-021?

A: The RCJ-021 is supplied in bag packaging. The 3514PCX packaging specification was not provided in the available data.

Q: Does the RCJ-021 operate across the same temperature range as the 3514PCX?

A: The RCJ-021 operates across -20°C to 85°C. Operating temperature specifications for the 3514PCX were not provided in the available data.
