TMM-112-02-S-S Equivalent & Substitute Parts

Part Overview

The TMM-112-02-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 12-position, single-row header operates at 2.00mm pitch and supports 3.2A per contact with an operating temperature range of -55°C to 125°C. The connector features gold-plated mating contacts and tin-plated posts with phosphor bronze contact material and liquid crystal polymer insulation. The product is active and ROHS3 compliant with MSL 1 rating. Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable or when alternative specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMM-112-02-S-S is evaluated based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (1)
• Pitch - mating (0.079" / 2.00mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact material (Phosphor Bronze)

Secondary Compatibility Factors:

• Operating temperature range
• Current rating per contact
• Contact finish specifications
• Insulation material properties
• RoHS and regulatory compliance

The substitute part M22-2011205 from Harwin Inc. matches all primary criteria and maintains compatibility with the core electrical and mechanical interface requirements. Variations in secondary parameters such as operating temperature range, current rating, and insulation material must be evaluated against specific application demands.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-112-02-S-S and M22-2011205 are active products with ROHS3 compliance and MSL 1 ratings, ensuring regulatory alignment and moisture handling compatibility.

TMM-112-02-S-S Selection Criteria:

• Applications requiring 3.2A per contact current capacity
• Operating environments up to 125°C
• Liquid crystal polymer insulation material preference
• Higher thermal performance requirements

M22-2011205 Selection Criteria:

• Applications with 1A per contact current requirements
• Operating environments up to 105°C
• Polyamide insulation material compatibility
• Cuttable header feature for custom configurations
• Applications where the reduced current rating is sufficient

Both connectors maintain identical pitch, position count, mounting type, and fastening mechanism, ensuring mechanical and electrical interface compatibility at the board level. Selection between these parts should be based on the specific current and temperature requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can M22-2011205 directly replace TMM-112-02-S-S in all applications?

A: Direct replacement is possible only when the application current requirement does not exceed 1A per contact and the maximum operating temperature does not exceed 105°C. The TMM-112-02-S-S supports 3.2A per contact and operates to 125°C, providing higher performance margins. Verify application specifications before substitution.

Q: What are the key differences between these two connectors?

A: The primary differences are current rating (3.2A vs. 1A per contact), maximum operating temperature (125°C vs. 105°C), insulation material (LCP vs. Polyamide), and the cuttable feature available on the M22-2011205. All other electrical and mechanical parameters, including pitch, position count, and contact material, are identical.

Q: Are both connectors compatible with the same mating connectors?

A: Both connectors share identical pitch (2.00mm), position count (12), and contact geometry. Mating compatibility depends on the specific mating connector design. Verify mating connector specifications with the connector manufacturer to ensure proper alignment and contact engagement.

Q: What does the cuttable feature on the M22-2011205 mean?

A: The cuttable feature allows the M22-2011205 header to be cut to a reduced number of positions while maintaining electrical and mechanical integrity. This feature is not available on the TMM-112-02-S-S.

Q: Are both parts RoHS compliant?

A: Yes, both TMM-112-02-S-S and M22-2011205 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current regulatory requirements for electronic component manufacturing and assembly.
