MJ-2505 Equivalent & Substitute Parts

Part Overview

The MJ-2505 is a 2.50mm mono phone jack connector manufactured by CUI Devices, designed for panel mount, through-hole applications with solder eyelet termination. This connector features a single internal switch, supports 1A current at 12VDC, and includes mounting hardware with thread lock. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJ-2505 is determined by the following critical parameters:

• Connector Type: Phone Jack (Female gender)
• Signal Configuration: Mono (single switch)
• Mating Diameter: 2.50mm headphone standard
• Contact Configuration: 2 Conductors, 3 Contacts
• Mounting Interface: Panel Mount, Through Hole with M4 thread
• Termination Method: Solder Eyelet(s)
• Electrical Ratings: 12VDC, 1A minimum
• Panel Hole Size: 0.197" (5.00mm)

The MJ1-2502 qualifies as a substitute based on matching all critical parameters. Variations in mounting orientation (right angle vs. straight), contact plating material, and housing material do not prevent functional substitution when panel layout and mechanical constraints permit.

Parameter Comparison

Engineering Selection Recommendations

The MJ1-2502 is the qualified substitute for the obsolete MJ-2505. Both connectors meet identical electrical and mechanical interface requirements for 2.50mm mono headphone jack applications.

Selection considerations based on provided specifications:

• Product Status: The MJ1-2502 maintains Active product status with current manufacturing support, whereas the MJ-2505 is Obsolete. For new designs or ongoing production, the MJ1-2502 is the appropriate choice.
• Compliance: Both parts are RoHS compliant. The MJ1-2502 carries ROHS3 certification, representing current compliance standards.
• Mounting Orientation: The MJ1-2502 includes right-angle mounting capability in addition to straight mounting. Panel layout constraints determine whether this feature is applicable.
• Material Composition: Housing material differs (PC vs. PBT) and contact plating differs (Silver vs. Tin). Both materials are suitable for the specified electrical and environmental parameters.

Frequently Asked Questions (FAQ)

Q: Can the MJ1-2502 directly replace the MJ-2505 in existing designs?

A: Yes, the MJ1-2502 is electrically and mechanically compatible with the MJ-2505. Both connectors share identical mating diameter (2.50mm), contact configuration (2 Conductors, 3 Contacts), electrical ratings (12VDC, 1A), and panel mounting interface (M4 thread, 0.197" hole size). The primary difference is mounting orientation; the MJ1-2502 offers right-angle mounting as an additional option.

Q: What is the difference between the contact plating materials?

A: The MJ-2505 uses silver plating, while the MJ1-2502 uses tin plating. Both materials provide adequate conductivity and corrosion resistance for the specified 12VDC, 1A application. Material selection does not affect functional compatibility.

Q: Are there packaging differences between these parts?

A: The MJ-2505 is supplied without specified packaging, while the MJ1-2502 is supplied in Tray packaging. This difference affects handling and storage procedures but does not impact electrical or mechanical performance.

Q: Why is the MJ-2505 listed as Obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The MJ1-2502 remains in active production and is the recommended source for ongoing component requirements.

Q: Do the housing material differences affect performance?

A: The MJ-2505 uses Polycarbonate (PC) housing, while the MJ1-2502 uses Polybutylene Terephthalate (PBT). Both materials are suitable for the specified operating temperature range and electrical environment. Material selection does not affect functional compatibility for this application.
