Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMM-150-03-S-D are identified based on strict electrical and mechanical compatibility within the TMM series. The primary substitution criterion is the maintenance of core connector specifications: 100-position capacity, 2-row configuration, 0.079" (2.00mm) pitch spacing, male pin contact type, through-hole mounting, and solder termination. The substitute part TMM-150-01-S-D shares all these critical parameters with the main part, ensuring functional interchangeability in applications requiring 100-position 2MM terminal strip headers.

The key parameters determining substitution eligibility are:

• Number of Positions: 100
• 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

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-150-03-S-D and TMM-150-01-S-D are active products from Samtec Inc. with identical ROHS3 compliance and MSL 1 ratings. The primary difference between these parts is the contact length specification: the TMM-150-03-S-D provides a mating contact length of 0.157" (4.00mm) with a post length of 0.106" (2.69mm), while the TMM-150-01-S-D offers a mating contact length of 0.126" (3.20mm) with a post length of 0.138" (4.60mm). Both maintain the same overall contact length of 0.323" (8.20mm).

Selection between these parts depends on the specific mating depth and post insertion requirements of the application. The TMM-150-03-S-D is suitable for applications requiring deeper mating contact engagement, while the TMM-150-01-S-D accommodates applications with greater post insertion depth requirements. Both parts maintain full electrical and thermal performance specifications across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can TMM-150-01-S-D be used as a direct replacement for TMM-150-03-S-D?

A: Both parts are functionally equivalent for 100-position, 2-row, 2MM pitch header applications. The primary difference is contact length geometry. Substitution is valid when the mating contact depth and post insertion depth of the receiving connector are compatible with the TMM-150-01-S-D specifications.

Q: What is the significance of the contact length differences between these parts?

A: Contact length determines the depth of engagement with the mating connector and the insertion depth of the solder post into the PCB. The TMM-150-03-S-D provides 0.157" mating contact length, while the TMM-150-01-S-D provides 0.126" mating contact length. Selection depends on the mechanical constraints of the mating interface and PCB thickness.

Q: Are both parts RoHS compliant?

A: Yes, both TMM-150-03-S-D and TMM-150-01-S-D are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the current-carrying capacity of these connectors?

A: Both parts are rated for 3.2A per contact across the full operating temperature range of -55°C to 125°C.

Q: Are these parts available in different packaging options?

A: Both parts are supplied in bulk packaging as standard.
