Key Parameters

Substitute Part Grouping Explanation

Substitution of the TM2REA-1812 is determined by strict equivalence across the following critical parameters:

• Connector type (Jack)
• Contact configuration (6p4c RJ11/RJ14)
• Port count (3)
• Mounting method (Through Hole)
• Orientation (90° Right Angle)
• Termination type (Solder)
• Shielding classification (Unshielded)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Housing material (PBT)
• Operating temperature range (-25°C ~ 80°C)
• Mechanical features (Board Lock, Panel Stops)

The TM2REA-1812(50) variant meets all these criteria and serves as a direct functional equivalent with improved product status and compliance profile.

Parameter Comparison

Engineering Selection Recommendations

The TM2REA-1812(50) is the appropriate substitute for the obsolete TM2REA-1812. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: TM2REA-1812(50) is active in production and ROHS3 compliant, whereas the original TM2REA-1812 is obsolete and RoHS non-compliant. For new designs and ongoing production, TM2REA-1812(50) provides supply chain continuity with enhanced compliance posture. Both parts share the same base product number (TM2RE) within the TM-DS series, confirming functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can TM2REA-1812(50) be used as a direct replacement for TM2REA-1812?

A: Yes. Both connectors are electrically and mechanically identical across all functional parameters including contact configuration, mounting method, orientation, termination type, and operating temperature range. The primary difference is product status and RoHS compliance.

Q: What is the difference between TM2REA-1812 and TM2REA-1812(50)?

A: The designation suffix (50) indicates a packaging variant (Tray) and reflects an active product status with ROHS3 compliance. The original TM2REA-1812 is obsolete and RoHS non-compliant. Electrical and mechanical specifications remain identical.

Q: Why is the original TM2REA-1812 marked as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The TM2REA-1812(50) variant provides continuity for this connector family with improved compliance and active supply availability.

Q: Are there any compatibility considerations when substituting these parts?

A: No compatibility issues exist. Both parts are functionally equivalent with identical pinout, mounting footprint, and electrical characteristics. Direct substitution is possible without design modification.

Q: What packaging options are available?

A: TM2REA-1812 was supplied in standard packaging, while TM2REA-1812(50) is supplied in Tray packaging. Both maintain identical component specifications.
