Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TM5RJ3-66(50) is determined by the following critical parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Number of Ports: 1
• Number of Rows: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Tab Direction: Up

The TM5RJ3-66(60) qualifies as a substitute part because it maintains identical values across all critical parameters. The primary difference is the shielding configuration: the main part includes shielding while the substitute is unshielded. This difference is acceptable in applications where electromagnetic interference protection is not required.

Parameter Comparison

Engineering Selection Recommendations

The TM5RJ3-66(60) is the designated manufacturer-recommended substitute for the obsolete TM5RJ3-66(50). Both parts maintain RoHS compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Selection between these parts depends on shielding requirements. The TM5RJ3-66(50) provides electromagnetic shielding, while the TM5RJ3-66(60) does not. The TM5RJ3-66(60) is recommended for applications where shielding is not a functional requirement, as it is currently in active production status and offers superior long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the TM5RJ3-66(60) directly replace the TM5RJ3-66(50)?

A: Yes, the TM5RJ3-66(60) is the manufacturer-recommended substitute. Both parts share identical connector type, contact configuration, mounting method, orientation, and termination. The primary difference is shielding; the substitute is unshielded.

Q: What is the impact of removing shielding when substituting?

A: Shielding provides electromagnetic interference (EMI) protection. Applications requiring EMI mitigation should retain the shielded variant. Applications without EMI sensitivity can use the unshielded substitute without functional impact.

Q: Are there packaging differences between these parts?

A: The TM5RJ3-66(50) packaging is not specified in available data. The TM5RJ3-66(60) is supplied in Tray packaging.

Q: Do both parts meet current compliance standards?

A: Yes. Both the TM5RJ3-66(50) and TM5RJ3-66(60) are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the TM5RJ3-66(50) marked as obsolete?

A: The TM5RJ3-66(50) has been discontinued by the manufacturer. The TM5RJ3-66(60) remains in active production and serves as the current equivalent for new designs and replacements.
