TM5RE1-44(50) Equivalent & Substitute Parts

Part Overview

The TM5RE1-44(50) is a modular jack connector from Hirose Electric's TM-DS series, designed for 4-position 4-contact (4p4c) applications compatible with RJ9, RJ10, and RJ22 standards. This right-angle unshielded connector features through-hole solder termination with board lock and panel stop features. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TM5RE1-44(50) is determined by strict equivalence across the following critical parameters:

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

The TM5RE1-44(20) meets all substitution criteria as a direct functional equivalent within the TM-DS series, differing only in packaging configuration and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TM5RE1-44(20) is the direct functional substitute for the obsolete TM5RE1-44(50). Both parts are electrically and mechanically identical across all critical connector parameters. The primary distinction is regulatory compliance: TM5RE1-44(20) is RoHS compliant, whereas TM5RE1-44(50) is RoHS non-compliant. For new designs or applications subject to RoHS requirements, TM5RE1-44(20) is the appropriate selection. The TM5RE1-44(20) carries Last Time Buy status, indicating limited future availability; procurement planning should account for this lifecycle phase.

Frequently Asked Questions (FAQ)

Q: Can TM5RE1-44(20) be used as a direct replacement for TM5RE1-44(50)?

A: Yes. Both connectors are functionally equivalent across all electrical and mechanical parameters, including contact configuration, orientation, termination method, and operating temperature range. Substitution is valid from a connector performance standpoint.

Q: What is the difference between these two part numbers?

A: The parts differ in packaging format and regulatory compliance. TM5RE1-44(50) uses unspecified packaging and is RoHS non-compliant. TM5RE1-44(20) uses tray packaging and is RoHS compliant. Electrical and mechanical specifications are identical.

Q: Why is TM5RE1-44(50) marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. TM5RE1-44(20) remains available as Last Time Buy, providing a transition path for existing applications.

Q: Are there any compatibility concerns when switching from TM5RE1-44(50) to TM5RE1-44(20)?

A: No compatibility concerns exist for connector function. Both parts maintain identical pinout, mechanical fit, and electrical characteristics. Packaging differences do not affect board-level integration.

Q: What does RoHS compliance mean for this connector?

A: RoHS compliance indicates the connector meets restrictions on hazardous substances. TM5RE1-44(20) is compliant; TM5RE1-44(50) is not. For applications in regulated industries or regions with RoHS mandates, TM5RE1-44(20) is required.

Q: Should I consider inventory planning for TM5RE1-44(20)?

A: Yes. Last Time Buy status indicates limited production window. Procurement should establish adequate stock levels before availability ends.
