Differing Parameter:

• Insulation Height: TFM-105-03-L-D-A = 0.220" (5.60mm); TFM-105-13-L-D-A = 0.290" (7.37mm)

The substitute part maintains electrical and mechanical compatibility while providing increased insulation height for applications requiring greater clearance or mechanical standoff.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-105-03-L-D-A and TFM-105-13-L-D-A are active products from Samtec Inc. with identical electrical ratings, compliance certifications, and mechanical compatibility. Selection between these parts depends solely on the required insulation height for the application:

• TFM-105-03-L-D-A (0.220" / 5.60mm insulation height): Use for standard applications with typical PCB clearance requirements.
• TFM-105-13-L-D-A (0.290" / 7.37mm insulation height): Use for applications requiring increased standoff distance or additional clearance above the PCB surface.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. Current inventory availability is 1012 units for TFM-105-03-L-D-A and 718 units for TFM-105-13-L-D-A.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between TFM-105-03-L-D-A and TFM-105-13-L-D-A?

A: The insulation height differs. TFM-105-03-L-D-A has 0.220" (5.60mm) insulation height, while TFM-105-13-L-D-A has 0.290" (7.37mm). All other electrical and mechanical specifications are identical.

Q: Are these connectors electrically interchangeable?

A: Yes. Both connectors have identical current ratings (2.9A per contact), voltage ratings (275VAC), contact materials, finishes, and operating temperature ranges (-55°C ~ 125°C).

Q: Can I use TFM-105-13-L-D-A as a direct replacement for TFM-105-03-L-D-A?

A: Yes, provided your PCB layout and mechanical clearance accommodate the increased insulation height of 0.290" (7.37mm) versus 0.220" (5.60mm).

Q: Do both parts have the same compliance certifications?

A: Yes. Both are ROHS3 compliant, UL94 V-0 rated, and have MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the pitch spacing for these connectors?

A: Both connectors have 0.050" (1.27mm) mating pitch and 0.050" (1.27mm) row spacing, with 10 positions arranged in 2 rows.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both connectors operate across -55°C to 125°C, suitable for industrial and automotive environments within this temperature range.
