TML-115-03-S-D Equivalent & Substitute Parts Reference

Part Overview

The TML-115-03-S-D is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This 30-position connector operates across the temperature range of -55°C to 125°C and features a 0.050" (1.27mm) pitch with 0.100" (2.54mm) row spacing. The part is currently active in production with 1023 units in stock. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where alternative connector configurations may be acceptable within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TML-115-03-S-D are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 30
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Style: Board to Board

The substitute parts 104068-3 and 5-104068-3 (both TE Connectivity AMP Connectors, AMPMODU System 50 series) satisfy these core mechanical and electrical interface requirements. Both substitutes maintain the same mating pitch, position count, row configuration, and through-hole solder termination necessary for direct PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

TML-115-03-S-D (Primary Part):

• Active product status with established supply (1023 units in stock)
• ROHS3 compliant
• Operating temperature range: -55°C ~ 125°C
• Shrouded 4-wall design with keying slot
• Phosphor bronze contact material with LCP insulation

104068-3 (TE Connectivity Substitute):

• Active product status with higher inventory availability (3320 units in stock)
• RoHS non-compliant; REACH affected
• Operating temperature range: -65°C ~ 105°C (lower maximum temperature)
• Shrouded 2-wall design with latch holder fastening
• Copper alloy contact material with thermoplastic insulation
• Packaging: Tube

5-104068-3 (TE Connectivity Substitute):

• Active product status with good inventory availability (1888 units in stock)
• ROHS3 compliant
• Operating temperature range: -65°C ~ 105°C (lower maximum temperature)
• Shrouded 2-wall design with latch holder fastening
• Copper alloy contact material with thermoplastic insulation
• Packaging: Tube
• REACH status: Vendor undefined

Selection between these parts depends on compliance requirements and operating temperature specifications. The 5-104068-3 offers ROHS3 compliance matching the primary part. All three parts maintain identical mating pitch, position count, and row spacing for PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can 104068-3 or 5-104068-3 be used as direct replacements for TML-115-03-S-D?

A: Both TE Connectivity parts share the same mating pitch (0.050"), position count (30), row spacing (0.100"), and through-hole solder termination. PCB footprints are compatible. However, differences exist in shrouding design (4-wall vs. 2-wall), fastening type (push-pull vs. latch holder), contact material, and insulation material. Physical mounting and mating interface characteristics differ.

Q: What are the temperature operating range differences?

A: TML-115-03-S-D operates from -55°C to 125°C. Both TE Connectivity substitutes operate from -65°C to 105°C. The TML-115-03-S-D provides higher maximum temperature capability (125°C vs. 105°C). Applications requiring operation above 105°C require the primary part.

Q: How do shrouding differences affect compatibility?

A: TML-115-03-S-D features 4-wall shrouding with keying slot. Both TE Connectivity substitutes feature 2-wall shrouding with latch holder fastening. Shrouding design affects mechanical protection, mating force, and connector retention. Mating connector compatibility must be verified based on specific shrouding and fastening requirements.

Q: What is the difference between 104068-3 and 5-104068-3?

A: Both parts are identical in electrical and mechanical specifications. The primary difference is RoHS compliance status: 104068-3 is RoHS non-compliant, while 5-104068-3 is ROHS3 compliant. For applications requiring RoHS compliance, 5-104068-3 is the appropriate TE Connectivity substitute.

Q: Are contact material differences significant?

A: TML-115-03-S-D uses phosphor bronze contacts; both TE Connectivity substitutes use copper alloy contacts. Both materials are gold-plated at the mating surface (30.0µin thickness). Contact material differences may affect mechanical durability and insertion force characteristics.

Q: What packaging differences exist?

A: TML-115-03-S-D is supplied in bulk packaging. Both TE Connectivity substitutes are supplied in tube packaging. Packaging affects handling, storage, and component presentation but does not affect electrical or mechanical performance.
