Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFC-110-02-LM-D-A is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Number of rows (2)
• Pitch - mating (0.050" / 1.27mm)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Current rating (3.1A per Contact)
• Voltage rating (275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer - LCP)

The identified substitute part TFC-110-02-L-D-A maintains full equivalence across all critical electrical and mechanical parameters, differing only in contact finish thickness specification documentation, which does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are TFC-110-02-LM-D-A and TFC-110-02-L-D-A electrically interchangeable?

A: Yes. Both parts are rated for 3.1A per contact at 275VAC and operate across the identical temperature range of -55°C to 125°C. Electrical performance and current-carrying capacity are equivalent.

Q: Do these connectors have identical mechanical dimensions?

A: Yes. Both connectors feature 20 positions in a 2-row configuration with 0.050" (1.27mm) pitch and row spacing. Mating contact length, insulation height, and overall form factor are identical, ensuring direct mechanical compatibility in board-to-board and cable applications.

Q: What is the difference between these part numbers?

A: The part numbers differ in their suffix designation (LM vs. L), which reflects internal Samtec product line documentation. All functional, electrical, and mechanical parameters remain equivalent. Both parts are manufactured from identical materials: Phosphor Bronze contacts with Liquid Crystal Polymer insulation.

Q: Are both parts RoHS compliant?

A: Yes. Both TFC-110-02-LM-D-A and TFC-110-02-L-D-A are ROHS3 compliant and carry identical environmental certifications including UL94 V-0 flammability rating.

Q: Can I use these connectors in high-temperature applications?

A: Both connectors are rated for continuous operation from -55°C to 125°C. Applications requiring operation beyond this range require alternative connector selection.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control requirements during storage or handling.

Q: Are these connectors suitable for push-pull mating applications?

A: Yes. Both connectors feature push-pull fastening type, enabling secure mating and demating cycles without additional fastening hardware.
