Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-115-02-S-D is determined by strict alignment of the following core parameters:

• Pitch - Mating: 0.050" (1.27mm) — mechanical and electrical compatibility requirement
• Number of Positions: 30 — functional capacity requirement
• Number of Rows: 2 — physical layout requirement
• Row Spacing - Mating: 0.100" (2.54mm) — board footprint compatibility requirement
• Connector Type: Header — functional classification
• Contact Type: Male Pin — mating interface requirement
• Mounting Type: Through Hole — PCB assembly method requirement
• Termination: Solder — connection method requirement
• Style: Board to Board or Board to Board/Cable — application compatibility

Both identified substitute parts (104068-3 and 5-104068-3) from TE Connectivity AMP Connectors meet all core substitution criteria. These parts are functionally equivalent for applications requiring 30-position, 0.050" pitch, dual-row header connectors with through-hole solder termination.

Engineering Selection Recommendations

Primary Part: TML-115-02-S-D

Select the TML-115-02-S-D when:

• ROHS3 compliance is required for the application
• Operating temperature range of -55°C to 125°C is necessary
• 4-wall shrouding design is specified for mechanical protection
• Push-pull fastening mechanism is preferred
• Phosphor bronze contact material is required
• Liquid Crystal Polymer insulation is specified
• Square contact geometry is required

Substitute Part: 5-104068-3 (Preferred TE Connectivity Alternative)

Select 5-104068-3 when:

• ROHS3 compliance is required
• Operating temperature range of -65°C to 105°C is acceptable
• 2-wall shrouding is acceptable for the application
• Latch holder fastening mechanism is acceptable
• Copper alloy contact material is acceptable
• Thermoplastic insulation is acceptable
• Circular contact geometry is acceptable
• Tin contact finish on posts is required (lead-free)
• Higher inventory availability (1888 units) is advantageous
• Tube packaging format is acceptable

Substitute Part: 104068-3 (Secondary TE Connectivity Alternative)

Select 104068-3 when:

• RoHS non-compliance is acceptable for the application
• Operating temperature range of -65°C to 105°C is acceptable
• 2-wall shrouding is acceptable
• Latch holder fastening mechanism is acceptable
• Tin-lead contact finish on posts is acceptable
• Highest inventory availability (3320 units) is critical for supply chain
• Tube packaging format is acceptable

Frequently Asked Questions (FAQ)

Q: Can 104068-3 and 5-104068-3 be used interchangeably with TML-115-02-S-D?

A: Both TE Connectivity parts are functionally equivalent for applications requiring 30-position, 0.050" pitch, dual-row header connectors with through-hole solder termination. However, design-specific requirements such as RoHS compliance, operating temperature range, shrouding design, fastening type, and contact finish must be verified before substitution. The 5-104068-3 is the preferred substitute due to ROHS3 compliance matching the primary part.

Q: What are the key differences between TML-115-02-S-D and the TE Connectivity substitutes?

A: Primary differences include: (1) Shrouding design (4-wall vs. 2-wall), (2) Fastening mechanism (push-pull vs. latch holder), (3) Contact length for mating (0.230" vs. 0.125"), (4) Contact shape (square vs. circular), (5) Insulation material (LCP vs. thermoplastic), (6) Operating temperature range (-55°C to 125°C vs. -65°C to 105°C), and (7) RoHS compliance status. These differences may affect mechanical fit, mating force, and environmental performance.

Q: Are there packaging format differences between these parts?

A: Yes. The TML-115-02-S-D is supplied in bulk packaging, while both TE Connectivity substitutes (104068-3 and 5-104068-3) are supplied in tube packaging. Tube packaging may require different handling and storage procedures. Verify packaging requirements for your assembly process before substitution.

Q: Which substitute part should be selected for new designs?

A: For new designs, 5-104068-3 is recommended as the primary substitute. It provides ROHS3 compliance matching the original part, acceptable operating temperature range for most applications, and higher inventory availability than the primary part. The 104068-3 should be considered only when RoHS non-compliance is acceptable and maximum inventory availability is the primary selection criterion.

Q: What is the impact of different contact lengths on substitution?

A: The TML-115-02-S-D has a mating contact length of 0.230" (5.84mm), while both TE Connectivity substitutes have 0.125" (3.18mm). This difference affects mating depth and may impact connector engagement characteristics. Verify that the shorter contact length of the substitute parts is compatible with your mating connector design before substitution.

Q: Are the fastening mechanisms compatible?

A: No. The TML-115-02-S-D uses push-pull fastening, while both TE Connectivity substitutes use latch holder fastening. These are different mechanical engagement systems. Verify that your mating connector or application supports latch holder fastening before substituting with TE Connectivity parts.

Q: What compliance certifications should be verified before substitution?

A: Verify RoHS compliance status for your application. The TML-115-02-S-D and 5-104068-3 are ROHS3 compliant, while 104068-3 is RoHS non-compliant. Additionally, verify UL94 V-0 flammability rating for the TE Connectivity parts if material flammability is a design requirement. Check REACH status requirements; 5-104068-3 shows vendor undefined status, while 104068-3 is REACH affected.
