T2M-115-01-L-D-TH Equivalent & Substitute Parts

Part Overview

The T2M-115-01-L-D-TH is a rectangular connector header manufactured by Samtec Inc. in the Tiger Eye™ T2M series. This through-hole mounted connector features 30 positions arranged in 2 rows with 0.079" (2.00mm) pitch, designed for board-to-board or cable applications. The part is Active status and ROHS3 compliant, making it suitable for current production designs. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative configurations within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T2M-115-01-L-D-TH are qualified based on the following critical parameters that must match or remain compatible:

Mandatory Matching Parameters:

• Number of Positions: 30
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Manufacturer: Samtec Inc.
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Series designation (Tiger Eye™ T2M vs. Flex Stack LTMM)
• Feature additions (Mating Flange, Solder Retention, Keying Slot)
• Operating temperature range (within -55°C minimum and 105°C or higher maximum)
• Insulation height (minor dimensional variations)
• Contact length specifications

The three substitute parts identified—T2M-115-01-L-D-TH-DS, T2M-115-01-L-D-TH-WT, and LTMM-115-02-L-D—satisfy these criteria and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and ROHS3 compliance, qualifying them for current production use. Selection between the main part and substitutes depends on specific design requirements:

T2M-115-01-L-D-TH-DS provides identical electrical and thermal specifications to the main part with the addition of a mating flange feature. This variant is suitable when mechanical alignment or strain relief is required at the mating interface.

T2M-115-01-L-D-TH-WT offers the same core specifications with solder retention feature and significantly higher inventory availability (18,800 units). This variant is appropriate for high-volume production runs or when solder joint reliability enhancement is desired.

LTMM-115-02-L-D represents a cross-series alternative from the Flex Stack LTMM line. While maintaining identical pitch, position count, and contact specifications, it operates at a maximum temperature of 105°C (versus 125°C for T2M variants) and features a keying slot. The reduced insulation height (0.190" vs. 0.228") may affect board layout compatibility. This part is suitable for applications where the lower temperature rating is acceptable and keying functionality provides design benefit.

Frequently Asked Questions (FAQ)

Q: Can T2M-115-01-L-D-TH-WT be used as a direct replacement for T2M-115-01-L-D-TH?

A: Yes. Both parts share identical electrical ratings (3.8A current, -55°C to 125°C operating range), mechanical dimensions, and contact specifications. The solder retention feature in the -WT variant is an enhancement that does not affect compatibility. PCB layout and mating connector requirements remain unchanged.

Q: What is the key difference between the T2M series and LTMM series substitutes?

A: The LTMM-115-02-L-D operates at a maximum temperature of 105°C compared to 125°C for T2M variants, and features a keying slot for polarization. The insulation height is 0.190" (4.83mm) versus 0.228" (5.80mm), which may require PCB layout verification. All other electrical and mechanical parameters are equivalent.

Q: Is the mating flange on T2M-115-01-L-D-TH-DS a required feature for substitution?

A: No. The mating flange is an additional feature that provides mechanical alignment and strain relief. Its presence does not prevent substitution; however, the mating connector must accommodate the flange geometry. If the mating connector is designed for the standard profile without flange, the -DS variant may not mate properly.

Q: Are all substitute parts available in the same packaging?

A: Yes. All parts listed are supplied in tube packaging, consistent with the main part specification.

Q: What inventory considerations should guide part selection?

A: T2M-115-01-L-D-TH-WT has the highest inventory availability at 18,800 units, making it the preferred choice for high-volume production. LTMM-115-02-L-D and T2M-115-01-L-D-TH-DS offer intermediate availability at 1,763 and 1,032 units respectively. The main part T2M-115-01-L-D-TH has 796 units in stock.
