TM5RE1-66(50) Equivalent & Substitute Parts
Part Overview
The TM5RE1-66(50) is a modular jack connector manufactured by Hirose Electric Co Ltd, designed for 6-position 6-contact (6p6c) applications including RJ11, RJ12, RJ14, and RJ25 standards. This connector features a 90° right-angle orientation with through-hole solder termination and unshielded construction. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation
Substitution eligibility for the TM5RE1-66(50) is determined by strict equivalence across the following critical parameters:
- Connector type (Jack)
- Contact configuration (6p6c RJ11/RJ12/RJ14/RJ25 compatibility)
- Orientation (90° right-angle)
- Mounting method (through-hole solder termination)
- 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, down tab direction)
The TM5RE1-66(20) meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is packaging format and product status, not functional or electrical characteristics.

Engineering Selection Recommendations
The TM5RE1-66(20) is the direct functional equivalent of the TM5RE1-66(50). Both connectors are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on the following factors:
For new designs and systems requiring regulatory compliance, the TM5RE1-66(20) is the appropriate choice due to its active product status and ROHS3 compliance certification. This part is currently in production and available in standard tray packaging.
For legacy system maintenance where the original TM5RE1-66(50) is specified, the TM5RE1-66(20) provides full functional compatibility without design modification. The connector maintains identical electrical performance, mechanical fit, and environmental operating characteristics.
The transition from RoHS non-compliant to ROHS3 compliant status reflects manufacturing process updates within the same connector family and does not affect functional performance in applications where the original part was qualified.
Frequently Asked Questions (FAQ)
Q: Can TM5RE1-66(20) be used as a direct replacement for TM5RE1-66(50)?
A: Yes. Both connectors are functionally equivalent across all electrical and mechanical parameters. The TM5RE1-66(20) is the active production equivalent of the obsolete TM5RE1-66(50).
Q: What is the difference between these two part numbers?
A: The primary differences are product status (obsolete vs. active), RoHS compliance level (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. tray). Functional specifications are identical.
Q: Are there any compatibility concerns when substituting TM5RE1-66(20) for TM5RE1-66(50)?
A: No compatibility concerns exist. Both connectors share identical contact configuration, orientation, mounting method, termination type, and operating temperature range. PCB footprints and mating characteristics are equivalent.
Q: Does the packaging difference affect connector performance?
A: No. Packaging format (tray vs. unspecified) affects only handling, storage, and logistics. Connector electrical and mechanical performance is unaffected by packaging type.
Q: Is the ROHS3 compliance upgrade significant for substitution?
A: ROHS3 compliance indicates updated manufacturing processes that meet current environmental regulations. This upgrade does not alter connector functionality and is beneficial for systems requiring regulatory compliance documentation.
Q: What is the base product number for these connectors?
A: The base product number is TM5R, which identifies the connector family within the TM-DS series.
