Key Parameters

Substitute Part Grouping Explanation

The TM2RE-1204(60) qualifies as a manufacturer-recommended substitute for the TM2RE-1204(50) based on the following critical parameters:

• Connector Configuration: Both parts maintain 6p2c (RJ11) jack configuration
• Mounting and Orientation: Identical through-hole vertical mounting
• Termination: Both use solder termination
• Shielding: Both are unshielded designs
• Tab Direction: Both feature user-selectable tab direction
• Regulatory Compliance: Both are RoHS compliant with MSL 1 rating
• Tariff Classification: Identical HTSUS code (8536.69.4040)

The primary distinction is product status: TM2RE-1204(50) is obsolete, while TM2RE-1204(60) is active and available in inventory.

Parameter Comparison

Engineering Selection Recommendations

The TM2RE-1204(60) is the designated manufacturer substitute for the obsolete TM2RE-1204(50). Both connectors maintain identical electrical and mechanical specifications across all critical parameters. The TM2RE-1204(60) is currently in active production with confirmed inventory availability (666 pcs), ensuring supply chain continuity. Both parts carry RoHS compliance certification and equivalent moisture sensitivity ratings, supporting regulatory requirements for modern electronics applications. Selection of the TM2RE-1204(60) eliminates obsolescence risk while maintaining full functional and dimensional compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the TM2RE-1204(60) be used as a direct replacement for the TM2RE-1204(50)?

A: Yes. The TM2RE-1204(60) is the manufacturer-recommended substitute. All critical parameters—connector configuration, mounting type, orientation, termination method, and shielding—are identical between the two parts.

Q: Are there any differences in contact material or finish between these parts?

A: The TM2RE-1204(50) specifies phosphor bronze contacts with gold finish. The TM2RE-1204(60) does not provide detailed contact material specifications in the available documentation. For applications requiring specific contact material verification, contact the manufacturer directly.

Q: What is the significance of the part number suffix (50 vs. 60)?

A: The suffix indicates different product series designations within the Hirose TM-DSA/TM-DS family. The TM2RE-1204(50) belongs to the TM-DSA series (obsolete), while the TM2RE-1204(60) belongs to the TM-DS series (active). The functional specifications remain equivalent.

Q: Are both parts suitable for the same operating temperature range?

A: The TM2RE-1204(50) is rated for -25°C to 80°C operation. The TM2RE-1204(60) does not specify an operating temperature range in the available data. Verify temperature requirements with the manufacturer if your application operates outside standard industrial ranges.

Q: Do both connectors have the same RoHS and MSL compliance?

A: Yes. Both parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory and handling requirements for electronics manufacturing.
