MTMM-112-09-F-D-000 Equivalent & Substitute Parts

Part Overview

The MTMM-112-09-F-D-000 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 24-position, 2-row connector operates at 0.079" (2.00mm) pitch and supports 3A current rating across an operating temperature range of -55°C to 125°C. The part is currently active in production status and maintains full RoHS3 compliance with UL94 V-0 flammability rating. Equivalent and substitute parts are identified to provide design flexibility for board-to-board or cable interconnection applications where mechanical or electrical parameter variations are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTMM-112-09-F-D-000 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Number of Positions: 24
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Variable Parameters Allowing Substitution:

• Overall Contact Length
• Insulation Height
• Contact Length - Mating
• Contact Length - Post

The identified substitute parts maintain all primary matching criteria while varying in contact length and insulation height specifications. These dimensional variations accommodate different PCB stack-up requirements and mating depth constraints without affecting electrical performance or compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active production status and full RoHS3 compliance with UL94 V-0 flammability certification, ensuring regulatory and environmental compliance across all options.

MTMM-112-09-F-D-366: This part shares the same series designation (MTMM) and maintains identical overall contact length and insulation height as the primary part. The specified contact length parameters (0.366" mating, 0.110" post) provide defined dimensional characteristics for applications requiring precise mating depth control.

TMMH-112-01-F-D and TMMH-112-01-FM-D: These parts represent the TMMH series with reduced overall contact length (0.302" versus 0.535") and increased insulation height (0.079" versus 0.059"). These dimensional reductions accommodate space-constrained applications and low-profile board designs. Both parts are functionally equivalent with identical contact specifications.

Selection between substitute parts depends on PCB stack-up requirements, available mating depth, and board-to-board spacing constraints. All parts maintain electrical performance equivalence for 24-position, 2-row, 2.00mm pitch header applications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the MTMM-112-09-F-D-000?

A: Substitution eligibility requires matching connector type (Header, Cuttable), contact type (Male Pin), position count (24), row configuration (2 rows), pitch (0.079" / 2.00mm), mounting method (Through Hole), termination (Solder), contact material (Phosphor Bronze), contact finish (Gold mating, Tin post), insulation material (LCP), operating temperature range (-55°C to 125°C), and flammability rating (UL94 V-0). Variations in overall contact length, insulation height, and specific contact length dimensions are permissible.

Q: Can TMMH series parts replace MTMM series parts?

A: Yes. TMMH-112-01-F-D and TMMH-112-01-FM-D maintain all critical electrical and mechanical parameters required for substitution. The primary difference is reduced overall contact length (0.302" versus 0.535") and increased insulation height (0.079" versus 0.059"), making these parts suitable for low-profile applications with tighter vertical space constraints.

Q: What is the difference between TMMH-112-01-F-D and TMMH-112-01-FM-D?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The designation difference reflects manufacturing or packaging variations within the TMMH-112 base product family.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for the primary part application.

Q: What inventory levels are available for substitute parts?

A: MTMM-112-09-F-D-366 has 1030 pieces in stock, TMMH-112-01-F-D has 937 pieces in stock, and TMMH-112-01-FM-D has 756 pieces in stock.
