Key Parameters

Substitute Part Grouping Explanation

Substitution within the TFM-115 connector family is determined by the following critical parameters that must remain constant:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 30
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts differ only in insulation height and contact finish post material, which are secondary mechanical characteristics that do not affect electrical performance or primary mating interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-115-12-L-D-A-P-TR, TFM-115-12-L-D-A-K-TR, and TFM-115-22-L-D-A-P-TR—are active products manufactured by Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. All parts maintain identical electrical specifications including current rating, voltage rating, and operating temperature range.

The primary distinction between TFM-115-12-L-D-A-P-TR and TFM-115-12-L-D-A-K-TR is the contact finish post material designation (P versus K), which does not affect mating interface performance or electrical characteristics.

The TFM-115-22-L-D-A-P-TR differs from TFM-115-12-L-D-A-P-TR only in insulation height (0.360" versus 0.290"), which is a mechanical accommodation parameter. This difference may be relevant for applications with specific board-to-board spacing requirements or stacking height constraints.

Selection among these parts should be based on specific application requirements for insulation height and available inventory levels.

Frequently Asked Questions (FAQ)

Q: Can TFM-115-12-L-D-A-K-TR be used as a direct replacement for TFM-115-12-L-D-A-P-TR?

A: Yes. Both parts share identical electrical and primary mechanical specifications. The difference in contact finish post material (K versus P designation) does not affect mating interface compatibility or electrical performance.

Q: What is the difference between TFM-115-12-L-D-A-P-TR and TFM-115-22-L-D-A-P-TR?

A: The primary difference is insulation height. TFM-115-12-L-D-A-P-TR has an insulation height of 0.290" (7.37mm), while TFM-115-22-L-D-A-P-TR has an insulation height of 0.360" (9.14mm). All other electrical and mechanical specifications are identical. Selection depends on board-to-board spacing and stacking height requirements.
