Key Parameters

Substitute Part Grouping Explanation

The substitute part TM3RA-44(50) is functionally equivalent to the main part TM3RA-44 based on the following critical parameters:

• Connector type, contact configuration (4p4c), and port/row count are identical
• Mounting method (through hole), orientation (vertical), and termination (solder) match exactly
• Shielding classification (unshielded) and board lock feature are preserved
• Contact material (phosphor bronze) and finish (gold) are identical
• Housing material (PBT) and operating temperature range (-25°C ~ 60°C) are the same
• Moisture sensitivity level (MSL 1) is equivalent

The primary difference is packaging format: TM3RA-44(50) is supplied in tray packaging, whereas the original part number does not specify packaging. Additionally, TM3RA-44(50) holds active product status with RoHS3 compliance, compared to the obsolete status of TM3RA-44.

Parameter Comparison

Engineering Selection Recommendations

The key advantage of TM3RA-44(50) is its active product status, ensuring continued availability and supply chain reliability. Additionally, TM3RA-44(50) achieves RoHS3 compliance, meeting current regulatory requirements for new designs and manufacturing processes. Both parts share equivalent REACH and ECCN classifications, maintaining consistent export and regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can TM3RA-44(50) be used as a direct replacement for TM3RA-44?

A: Yes. Both parts are identical in connector type, contact configuration (4p4c), mounting method (through hole vertical), termination (solder), and all electrical and mechanical specifications. The substitute part is functionally equivalent for all applications requiring the TM3RA-44.

Q: What is the difference between TM3RA-44 and TM3RA-44(50)?

A: The primary differences are product status and compliance. TM3RA-44(50) is an active product with RoHS3 compliance, while TM3RA-44 is obsolete and RoHS non-compliant. Packaging differs: TM3RA-44(50) is supplied in tray format. All electrical and mechanical parameters remain identical.

Q: Why is TM3RA-44 marked as obsolete?

A: The obsolete status indicates that Hirose Electric Co Ltd has discontinued this specific part number. TM3RA-44(50) is the active equivalent and recommended for all new applications and replacements.

Q: Are there any compatibility concerns when switching from TM3RA-44 to TM3RA-44(50)?

A: No compatibility concerns exist. Both connectors maintain identical specifications for connector type, contact configuration, mounting orientation, termination method, and operating temperature range. Physical and electrical compatibility is preserved.

Q: Does the tray packaging of TM3RA-44(50) affect its performance?

A: No. Packaging format does not affect connector performance or specifications. Tray packaging is a supply and handling format only and does not impact electrical or mechanical function.

Q: Is RoHS3 compliance important for my application?

A: RoHS3 compliance is required for products sold in the European Union and many other markets. If your application or end-market requires RoHS compliance, TM3RA-44(50) is the appropriate choice. The original TM3RA-44 is RoHS non-compliant.
