TMM-115-03-TM-D Equivalent & Substitute Parts

Part Overview

The TMM-115-03-TM-D is a 2MM terminal strip connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections. This 30-position, 2-row rectangular connector features male pins with 0.079" (2.00mm) pitch spacing and is rated for 3.2A per contact at operating temperatures from -55°C to 105°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-115-03-TM-D is determined by strict equivalence across the following critical parameters: connector type (Header), contact type (Male Pin), pitch spacing (0.079" / 2.00mm), number of positions (30), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (Through Hole), termination method (Solder), current rating (3.2A per Contact), operating temperature range (-55°C ~ 105°C), contact material (Phosphor Bronze), and insulation material (Liquid Crystal Polymer). The identified substitute part maintains all these parameters identically. Packaging differences (tape and reel versus bulk) do not affect electrical or mechanical compatibility and represent the only variation between the main part and its substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-115-03-TM-D and TMM-115-03-T-D are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The TMM-115-03-TM-D is supplied in tape and reel packaging, while the TMM-115-03-T-D is supplied in bulk packaging. Both parts maintain ROHS3 compliance and EAR99 export classification. Current inventory levels show 967 units of TMM-115-03-TM-D and 1076 units of TMM-115-03-T-D available as new original stock.

Frequently Asked Questions (FAQ)

Q: Are TMM-115-03-TM-D and TMM-115-03-T-D electrically interchangeable?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector type, contact configuration, pitch spacing, current rating, and operating temperature range. The only difference is packaging format.

Q: What is the difference between tape and reel packaging and bulk packaging?

A: Tape and reel packaging (TMM-115-03-TM-D) is designed for automated assembly processes and provides organized component storage on continuous tape. Bulk packaging (TMM-115-03-T-D) supplies components in loose form. Selection depends on manufacturing process requirements and assembly equipment compatibility.

Q: Can I use TMM-115-03-T-D as a direct replacement for TMM-115-03-TM-D in my design?

A: Yes, from an electrical and mechanical standpoint, TMM-115-03-T-D is a direct substitute. Verify that your assembly process can accommodate the bulk packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both TMM-115-03-TM-D and TMM-115-03-T-D are ROHS3 compliant.

Q: What is the current rating per contact?

A: Both parts are rated for 3.2A per contact at the specified operating temperature range of -55°C to 105°C.
