Key Parameters

Substitute Part Grouping Explanation

The TM3RA1-44(50) qualifies as a direct substitute for the TM3RA1-44(67) based on the following critical parameters:

Matching Electrical and Mechanical Specifications:

• Connector type: Jack
• Contact configuration: 4p4c (RJ9, RJ10, RJ22)
• Port and row configuration: 1 port, 1 row
• Mounting and orientation: Through hole, vertical
• Termination method: Solder
• Shielding classification: Unshielded
• Board lock feature: Present
• Contact material and finish: Phosphor bronze with gold plating
• Housing material: Polybutylene terephthalate (PBT)
• Compliance: RoHS compliant
• Moisture sensitivity: MSL 1 (unlimited)

The primary difference between these parts is packaging format: TM3RA1-44(67) is supplied in trays, while TM3RA1-44(50) is supplied in bulk. This distinction does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TM3RA1-44(50) is the direct substitute for the TM3RA1-44(67). Both parts are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications. The TM3RA1-44(50) maintains active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

Both parts carry RoHS compliance certification and MSL 1 rating, meeting regulatory and environmental requirements for standard industrial applications. The packaging difference (tray versus bulk) does not affect functional compatibility and should be evaluated based on procurement and assembly workflow requirements.

Frequently Asked Questions (FAQ)

Q: Can TM3RA1-44(50) be used as a direct replacement for TM3RA1-44(67)?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector type, contact configuration (4p4c), mounting method (through hole, vertical), termination (solder), and material specifications. The only difference is packaging format.

Q: What is the significance of the packaging difference between tray and bulk?

A: Packaging format affects handling, storage, and assembly processes but does not impact electrical or mechanical performance. Tray packaging typically provides better component protection during storage and handling, while bulk packaging may offer cost advantages for high-volume production.

Q: Are both parts RoHS compliant?

A: Yes. Both TM3RA1-44(67) and TM3RA1-44(50) are RoHS compliant and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: Why is TM3RA1-44(67) marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this specific part number. The TM3RA1-44(50) remains in active production and serves as the recommended alternative for ongoing supply requirements.

Q: Are there any compatibility considerations for PCB design?

A: No. Both parts use identical through-hole mounting specifications and vertical orientation. Existing PCB designs for TM3RA1-44(67) require no modification to accommodate TM3RA1-44(50).
