Key Parameters

Substitute Part Grouping Explanation

The MJ1-2502 qualifies as a direct substitute for the MJ-2502 based on the following critical parameters:

• Connector Type & Signal Configuration: Both are mono phone jack connectors with identical signal line architecture
• Mating Diameter & Contact Count: Both feature 2.50mm mating diameter with 2 conductors and 3 contacts
• Mounting Specifications: Both are panel-mount, through-hole, right-angle connectors with identical panel hole size (0.197", 5.00mm) and thread size (M4)
• Termination Method: Both use solder eyelet termination
• Electrical Ratings: Both are rated for 12VDC and 1 A current
• Housing & Contact Materials: Both use PBT housing and brass contacts
• Compliance Status: Both are RoHS compliant and REACH unaffected

The primary distinction is product status: MJ-2502 is obsolete, while MJ1-2502 is active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The MJ1-2502 is the direct active equivalent for the obsolete MJ-2502. Both connectors meet identical mechanical and electrical specifications for 2.50mm mono phone jack applications with panel-mount, through-hole, right-angle configuration.

The MJ1-2502 offers the following advantages:

• Active product status with manufacturer support and continued availability
• Higher inventory levels (1895 units versus 966 units)
• ROHS3 compliance, representing current regulatory alignment
• Tray packaging suitable for automated assembly processes

The contact plating difference (silver on MJ-2502 versus tin on MJ1-2502) does not affect functional compatibility, as both materials provide adequate conductivity and corrosion resistance for the specified 12VDC, 1 A application. The MJ1-2502 contact material specification includes both brass and copper alloy options, maintaining electrical performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can MJ1-2502 be used as a direct replacement for MJ-2502 in existing designs?

A: Yes. The MJ1-2502 is mechanically and electrically equivalent to the MJ-2502. Both connectors feature identical mating diameter (2.50mm), contact count (2 conductors, 3 contacts), mounting configuration (panel mount, through hole, right angle), and electrical ratings (12VDC, 1 A). Panel hole size and thread size are identical (0.197", M4), ensuring direct PCB and panel compatibility.

Q: What is the significance of the contact plating difference?

A: The MJ-2502 features silver-plated contacts, while the MJ1-2502 features tin-plated contacts. Both plating materials provide adequate conductivity and corrosion resistance for the specified application. The plating difference does not affect functional performance or mating compatibility.

Q: Are there any compliance differences between these connectors?

A: Both connectors are RoHS compliant and REACH unaffected. The MJ1-2502 carries ROHS3 certification, representing alignment with current regulatory standards. The MJ-2502 carries RoHS compliance designation. Both meet applicable environmental and safety requirements.

Q: What packaging options are available?

A: The MJ-2502 packaging specification is not provided in available documentation. The MJ1-2502 is supplied in tray packaging, suitable for automated assembly and high-volume production environments.

Q: Why is the MJ-2502 classified as obsolete?

A: The MJ-2502 has been superseded by the MJ1-2502 in the CUI Devices product line. The MJ1-2502 is the active equivalent offering identical functionality with current manufacturer support and improved availability.
