TC-100-SM SMA Coaxial Connector Plug Equivalent & Substitute Parts

Part Overview

The TC-100-SM is an SMA male plug coaxial connector manufactured by Amphenol Times Microwave Systems, designed for 50-ohm RF applications with free-hanging (in-line) solder termination. This connector is rated for operation up to 3 GHz and features a crimp shield termination with gold-plated beryllium copper center contact.

The TC-100-SM is classified as obsolete. Locating equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for repair, maintenance, and new installations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC-100-SM is based on strict equivalence of the following critical parameters:

• Connector Style: SMA (ensures mechanical and electrical compatibility)
• Connector Type: Plug, Male Pin (maintains interface compatibility)
• Impedance: 50 Ohms (preserves RF performance characteristics)
• Contact Termination: Solder (ensures compatible assembly methods)
• Shield Termination: Crimp (maintains shielding approach)
• Mounting Type: Free Hanging (In-Line) (preserves installation configuration)
• Fastening Type: Threaded (ensures mating compatibility)
• Cable Group: LMR-100 (maintains cable compatibility)

The SC-100-SM meets all these critical substitution criteria. While the SC-100-SM exhibits enhanced specifications in frequency range (6 GHz vs. 3 GHz), operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C), and mating cycles (500), these represent improvements that do not compromise backward compatibility with TC-100-SM applications.

Parameter Comparison

Engineering Selection Recommendations

The SC-100-SM is the direct substitute for the TC-100-SM based on product status and compliance criteria:

The TC-100-SM is obsolete and no longer in active production. The SC-100-SM is an active product from the same manufacturer with identical core electrical and mechanical specifications. Both parts are RoHS compliant and carry MSL rating 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

The SC-100-SM provides enhanced performance specifications (higher frequency rating and extended operating temperature range) while maintaining full backward compatibility with TC-100-SM applications. The SC-100-SM is the appropriate selection for new designs and replacement applications where TC-100-SM connectors are specified.

Frequently Asked Questions (FAQ)

Q: Can SC-100-SM be used as a direct replacement for TC-100-SM?

A: Yes. The SC-100-SM meets all critical substitution parameters: identical SMA connector style, male plug configuration, 50-ohm impedance, solder contact termination, crimp shield termination, free-hanging mounting, threaded fastening, and LMR-100 cable group compatibility. Both parts are RoHS compliant with MSL 1 rating.

Q: What are the differences between TC-100-SM and SC-100-SM?

A: The SC-100-SM offers enhanced specifications: maximum frequency of 6 GHz (vs. 3 GHz), extended operating temperature range to 125°C (vs. 85°C), and rated mating cycles of 500. Center contact material differs (brass vs. beryllium copper) and body material differs (brass vs. stainless steel). These differences represent performance improvements that do not affect compatibility.

Q: Are there packaging differences between these parts?

A: The TC-100-SM packaging is not specified in available data. The SC-100-SM is supplied in bag packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts support the same cable types?

A: Yes. Both TC-100-SM and SC-100-SM are rated for LMR-100 cable group, ensuring identical cable compatibility.

Q: What is the compliance status of both parts?

A: Both parts are RoHS compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental compliance and handling requirements.
