Substitute Part Grouping Explanation

Substitution of the TML-110-03-G-D is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 20
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Style: Board to Board compatibility

The substitute part 5-104068-1 (TE Connectivity AMP Connectors) satisfies all primary substitution criteria. Both parts maintain identical position count, pitch spacing, row configuration, and through-hole solder termination. Both are active products with ROHS3 compliance and EAR99 classification.

Secondary Compatibility Factors:

• Operating temperature ranges differ: TML-110-03-G-D operates -55°C ~ 125°C; 5-104068-1 operates -65°C ~ 105°C
• Shrouding configuration differs: TML-110-03-G-D features 4-wall shrouding; 5-104068-1 features 2-wall shrouding
• Contact geometry differs: TML-110-03-G-D uses square contacts; 5-104068-1 uses circular contacts
• Fastening mechanism differs: TML-110-03-G-D uses push-pull fastening; 5-104068-1 uses latch holder fastening

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TML-110-03-G-D): Select the TML-110-03-G-D when applications require the extended upper operating temperature limit of 125°C, 4-wall shrouding for enhanced EMI shielding, square contact geometry, or push-pull fastening mechanisms. This part is suitable for industrial and high-temperature environments. Both the primary part and substitute maintain ROHS3 compliance and EAR99 classification.

Substitute Part Selection (5-104068-1): Select 5-104068-1 when applications operate within the -65°C to 105°C temperature range and can accommodate 2-wall shrouding, circular contact geometry, and latch holder fastening. This substitute offers higher inventory availability (2200 units versus 740 units) and supports both board-to-board and cable applications. The substitute includes a specified 30VAC voltage rating and UL94 V-0 flammability rating, providing additional compliance documentation for specific applications.

Compatibility Constraints: Direct mechanical and electrical interchangeability is not guaranteed due to differences in shrouding configuration, contact geometry, fastening mechanisms, and contact length specifications. Physical fit verification and electrical performance validation are required before design implementation. The substitute part's lower maximum operating temperature (105°C versus 125°C) may restrict use in high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can 5-104068-1 be used as a direct replacement for TML-110-03-G-D in existing designs?

A: Both parts share identical pitch (0.050"), row spacing (0.100"), position count (20), and row configuration (2 rows). However, differences in shrouding (4-wall versus 2-wall), contact geometry (square versus circular), fastening type (push-pull versus latch holder), and operating temperature ranges require design verification. Physical fit and electrical performance must be validated before implementation.

Q: What are the key differences in operating temperature capability?

A: The TML-110-03-G-D operates from -55°C to 125°C, while the 5-104068-1 operates from -65°C to 105°C. The TML-110-03-G-D provides a 20°C higher upper temperature limit, making it suitable for applications requiring extended high-temperature operation. The 5-104068-1 provides a 10°C lower minimum temperature capability.

Q: How do the shrouding configurations differ?

A: The TML-110-03-G-D features 4-wall shrouding, providing enhanced electromagnetic interference (EMI) shielding and mechanical protection. The 5-104068-1 features 2-wall shrouding, offering reduced profile and cost while maintaining basic connector protection. Application requirements for EMI performance determine which configuration is appropriate.

Q: What is the significance of contact geometry differences?

A: The TML-110-03-G-D uses square contacts, while the 5-104068-1 uses circular contacts. Contact geometry affects mating force, contact resistance, and mechanical durability. Square contacts typically provide higher contact pressure and lower resistance. Circular contacts offer different wear characteristics and mating force profiles. Connector receptacles must be designed for the specific contact geometry.

Q: How do fastening mechanisms affect connector selection?

A: The TML-110-03-G-D uses push-pull fastening, while the 5-104068-1 uses latch holder fastening. Push-pull mechanisms provide quick-disconnect capability with axial force engagement. Latch holder mechanisms provide positive retention with latching features. Application requirements for connector retention and disconnect frequency determine which fastening type is appropriate.

Q: Are both parts RoHS compliant?

A: Yes, both TML-110-03-G-D and 5-104068-1 are ROHS3 compliant and classified as EAR99 for export control purposes. Both parts are suitable for applications requiring RoHS compliance.

Q: What packaging differences exist between these parts?

A: The TML-110-03-G-D is supplied in bulk packaging, while the 5-104068-1 is supplied in tube packaging. Packaging affects handling, storage, and automated assembly compatibility. Verify packaging requirements with assembly processes before part selection.

Q: Which part has better inventory availability?

A: The 5-104068-1 has significantly higher inventory availability with 2200 units in stock compared to 740 units for the TML-110-03-G-D. Higher inventory availability may support shorter lead times and reduced procurement risk for high-volume applications.
