Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TM5RF1-44 is determined by strict equivalence across the following critical parameters:

• Connector type (Jack)
• Contact configuration (4p4c / RJ9, RJ10, RJ22)
• Orientation (90° right-angle)
• Mounting method (through-hole solder)
• Shielding classification (unshielded)
• Contact material and finish (phosphor bronze with gold plating)
• Housing material (PBT)
• Operating temperature range (-25°C ~ 60°C)
• Mechanical features (board lock, panel stops, side tab direction)

The substitute part TM5RF1-44(50) maintains identical electrical and mechanical specifications across all these parameters, differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TM5RF1-44(50) serves as the direct functional equivalent to the obsolete TM5RF1-44. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and footprint compatibility in circuit board applications.

The primary distinction between these parts is regulatory compliance status. The TM5RF1-44(50) is RoHS Compliant, whereas the original TM5RF1-44 is RoHS non-compliant. For applications subject to RoHS directives or requiring compliance documentation, the TM5RF1-44(50) is the appropriate selection.

The TM5RF1-44(50) carries a Last Time Buy status, indicating limited availability. Procurement planning should account for this lifecycle phase when establishing long-term component sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can TM5RF1-44(50) be used as a direct replacement for TM5RF1-44?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including connector type, contact configuration, orientation, mounting method, and operating temperature range. The parts are interchangeable at the circuit board level.

Q: What is the difference between TM5RF1-44 and TM5RF1-44(50)?

A: The primary differences are packaging format (tray for the (50) variant) and regulatory compliance status. The TM5RF1-44(50) is RoHS Compliant, while the original TM5RF1-44 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Why is the original TM5RF1-44 marked as obsolete?

A: The obsolete status reflects the part's removal from active manufacturing. The TM5RF1-44(50) represents the current production equivalent with updated compliance certifications.

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

A: No compatibility concerns exist. Both parts share identical footprints, pin configurations, and mechanical mounting requirements. Substitution requires no circuit board redesign or assembly process modification.

Q: What does Last Time Buy status mean for the TM5RF1-44(50)?

A: Last Time Buy indicates this is the final production run of this part number. After current inventory is depleted, the part will transition to obsolete status. Long-term applications should establish alternative sourcing strategies or secure adequate inventory during this window.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and hazardous substance restrictions, not electrical or mechanical performance. Both parts deliver identical functional characteristics in circuit applications.
