Switchcraft 3501FR RCA Phono Jack Mono Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 3501FR is a 3.20mm ID, 9.00mm OD (RCA) phono jack mono connector designed for panel mount applications with solder eyelet termination. This connector features a grounding tab, mounting hardware, and nickel-plated brass construction with black insulation. The 3501FR is currently listed as obsolete product status, making identification of active equivalent parts essential for ongoing production and maintenance applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Switchcraft 3501FR is determined by strict equivalence across the following critical parameters:

• Connector Type: Phono (RCA) Jack
• Gender: Female
• Signal Lines: Mono
• Industry Recognized Mating Diameter: 3.20mm ID, 9.00mm OD (RCA)
• Number of Positions/Contacts: 2 Conductors, 2 Contacts
• Mounting Type: Panel Mount
• Termination: Solder Eyelet(s)
• Shielding: Unshielded
• Panel Hole Size: 0.375" (9.52mm)
• Thread Size: 3/8"-32
• Contact Material - Plating: Nickel
• Body Material: Brass

The Switchcraft 3501FRX meets all substitution criteria as a direct equivalent part with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 3501FRX is the direct functional equivalent to the obsolete 3501FR. Both parts share identical electrical and mechanical specifications across all critical parameters including connector type, mating diameter, contact configuration, mounting interface, and termination method.

The primary distinction between these parts is product status and regulatory compliance. The 3501FR is obsolete, while the 3501FRX maintains active product status with significantly higher inventory availability (10,935 units versus 718 units). The 3501FRX additionally meets ROHS3 compliance requirements, whereas the 3501FR is RoHS non-compliant.

For new designs and ongoing production requiring this connector type, the Switchcraft 3501FRX is the appropriate selection. For legacy system maintenance where the original 3501FR specification must be maintained, the 3501FRX provides full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 3501FR and 3501FRX electrically and mechanically interchangeable?

A: Yes. Both connectors share identical specifications for connector type, mating diameter (3.20mm ID, 9.00mm OD RCA), contact configuration (2 conductors, 2 contacts), mounting type (panel mount), termination method (solder eyelet), and all mechanical dimensions including panel hole size (0.375" / 9.52mm) and thread size (3/8"-32).

Q: What is the primary reason to transition from 3501FR to 3501FRX?

A: The 3501FR is obsolete product status. The 3501FRX is the active equivalent part with superior inventory availability and ROHS3 compliance certification.

Q: Will the 3501FRX fit existing panel cutouts designed for the 3501FR?

A: Yes. The panel hole size (0.375" / 9.52mm) and thread size (3/8"-32) are identical between both parts, ensuring direct mechanical compatibility with existing panel installations.

Q: Are there packaging differences between these parts?

A: The 3501FR packaging specification is not provided. The 3501FRX is supplied in bulk packaging. Both parts include 3 pieces per unit: 1 connector, 1 nut, and 1 washer.

Q: Does the RoHS compliance difference affect connector performance?

A: RoHS compliance relates to material composition and regulatory requirements, not electrical or mechanical performance. Both parts maintain identical contact material (nickel-plated brass) and body construction (brass).
