Key Parameters

Substitute Part Grouping Explanation

Substitution for the TM18R-TO-88 is determined by strict equivalence across the following critical parameters:

• Connector type (Jack)
• Contact configuration (8P8C / RJ45)
• Mounting method (Surface Mount)
• Orientation (90° right-angle)
• Termination method (Solder)
• Shielding classification (Unshielded)
• Contact material and finish specifications
• Housing material (PPS)
• Operating temperature range (-25°C to 80°C)
• Functional features (Board Guide, Solder Retention)

The TM18R-TO-88(50) qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The TM18R-TO-88(50) is the direct substitute for the obsolete TM18R-TO-88. Both parts maintain identical electrical and mechanical specifications across all functional parameters.

Key selection considerations:

• The TM18R-TO-88(50) carries Active product status, ensuring ongoing manufacturer support and supply availability.
• The TM18R-TO-88(50) is ROHS3 compliant, meeting current regulatory requirements for electronic components in most jurisdictions.
• The original TM18R-TO-88 is RoHS non-compliant and obsolete, making it unsuitable for new designs or long-term supply planning.
• Both parts are REACH Unaffected and classified under ECCN EAR99.
• Packaging format differs (Tray for the substitute), which may affect procurement and assembly workflows but does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the TM18R-TO-88(50) be used as a direct replacement for the TM18R-TO-88?

A: Yes. The TM18R-TO-88(50) is electrically and mechanically equivalent to the TM18R-TO-88 across all functional parameters, including connector type, contact configuration, mounting method, orientation, termination, and operating specifications.

Q: What is the difference between TM18R-TO-88 and TM18R-TO-88(50)?

A: The primary differences are product status, regulatory compliance, and packaging. The TM18R-TO-88(50) is Active (versus Obsolete), ROHS3 Compliant (versus non-compliant), and supplied in Tray packaging. All electrical and mechanical specifications are identical.

Q: Why is the TM18R-TO-88 classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued active production and support. The TM18R-TO-88(50) represents the current production equivalent.

Q: Are there any compatibility concerns when switching from TM18R-TO-88 to TM18R-TO-88(50)?

A: No compatibility concerns exist for electrical or mechanical integration. The substitute maintains identical pinout, contact configuration, mounting footprint, and performance characteristics. Packaging format (Tray) may require adjustment in procurement and assembly processes.

Q: What is the significance of the RoHS compliance difference?

A: ROHS3 compliance indicates the TM18R-TO-88(50) meets current Restriction of Hazardous Substances regulations, making it suitable for applications subject to environmental and regulatory standards. The non-compliant status of the original part may restrict its use in regulated markets.

Q: Is the TM18R-TO-88(50) available in the same quantities as the original part?

A: Availability depends on current inventory and supply chain conditions. The TM18R-TO-88(50) is classified as Active, indicating ongoing production and availability through authorized distributors.
