TM5RC-66 Equivalent & Substitute Parts

Part Overview

The TM5RC-66 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. The connector features a 90° right-angle orientation with through-hole solder termination and board lock functionality. The main part number TM5RC-66 is currently classified as obsolete, making substitute part identification essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The substitute part TM5RC-66(50) is classified as a direct equivalent based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Connector type (Jack)
• Contact configuration (6p6c)
• Mounting method (Through Hole)
• Orientation (90° Right Angle)
• Termination method (Solder)
• Shielding classification (Unshielded)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Housing material (PBT)
• Operating temperature range (-25°C ~ 60°C)
• Functional features (Board Lock, Tab Direction Up)

The TM5RC-66(50) maintains full parameter alignment with the main part across all specified electrical and mechanical characteristics, differing only in packaging format (Tray) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TM5RC-66(50) is the direct substitute for the obsolete TM5RC-66. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction lies in regulatory compliance and product lifecycle status.

The TM5RC-66 is RoHS non-compliant and classified as obsolete, indicating end-of-life status with no further manufacturing planned. The TM5RC-66(50) is ROHS3 compliant and designated as Last Time Buy, providing a defined procurement window for transition planning.

For new designs or ongoing production requiring 6p6c modular jack connectors with 90° right-angle orientation and through-hole solder termination, the TM5RC-66(50) is the appropriate selection. For legacy systems currently using TM5RC-66, direct substitution with TM5RC-66(50) is electrically and mechanically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: Can TM5RC-66(50) be used as a direct replacement for TM5RC-66?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including connector type, contact configuration, mounting method, orientation, termination, shielding, contact materials, housing material, and operating temperature range.

Q: What is the difference between TM5RC-66 and TM5RC-66(50)?

A: The primary differences are packaging format (standard vs. Tray), product lifecycle status (Obsolete vs. Last Time Buy), and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Why is TM5RC-66 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and will not accept new orders. The TM5RC-66(50) variant remains available under Last Time Buy status, providing a defined procurement window before complete discontinuation.

Q: Are there any compatibility concerns when substituting TM5RC-66(50) for TM5RC-66?

A: No compatibility concerns exist. The parts are functionally equivalent with identical pin configurations, mounting footprints, and electrical characteristics. Existing PCB designs and assemblies require no modification.

Q: What does Last Time Buy status mean for TM5RC-66(50)?

A: Last Time Buy indicates a final procurement window during which the manufacturer will accept orders before production ends. After this period, the part will transition to obsolete status. Procurement planning should account for this timeline.

Q: Is RoHS3 compliance a functional requirement for connector selection?

A: RoHS3 compliance is a regulatory requirement for products sold in certain markets. The TM5RC-66(50) meets this requirement, while the original TM5RC-66 does not. Selection depends on applicable regulatory requirements for your application and market.
