Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-115-22-L-D-A is determined by strict alignment of the following critical parameters:

• Manufacturer and Series: Samtec Inc., Tiger Eye™ TFM series
• Connector Type and Contact Type: Header with Male Pin contacts
• Position and Row Configuration: 30 positions, 2 rows
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting and Fastening: Surface Mount with Push-Pull fastening
• Electrical Ratings: 2.9A per contact, 275VAC
• Temperature Range: -55°C ~ 125°C
• Compliance: ROHS3 Compliant, UL94 V-0 flammability rating

The substitute part TFM-115-32-L-D-A meets all these critical parameters. The primary difference is the Insulation Height (0.435" vs. 0.360"), which represents a mechanical variation within the same connector family and does not affect electrical compatibility or functional performance in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-115-22-L-D-A and TFM-115-32-L-D-A are Active status products from Samtec Inc., ensuring ongoing manufacturer support and availability. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for modern electronics manufacturing.

The TFM-115-32-L-D-A represents a direct functional equivalent with identical electrical performance, contact configuration, and mating characteristics. The increased insulation height (0.435" versus 0.360") is a mechanical design variation that does not compromise electrical compatibility or performance in standard board-to-board interconnection applications.

Selection between these parts should be based on specific PCB layout requirements and available inventory. The TFM-115-32-L-D-A currently has higher inventory availability (1396 Pcs versus 749 Pcs), which may influence procurement decisions.

Frequently Asked Questions (FAQ)

Q: Are TFM-115-22-L-D-A and TFM-115-32-L-D-A electrically interchangeable?

A: Yes. Both parts share identical electrical ratings (2.9A per contact, 275VAC), operating temperature range (-55°C ~ 125°C), contact materials, and finishes. They are electrically equivalent for all standard applications.

Q: What is the difference between these two parts?

A: The primary difference is the Insulation Height: TFM-115-22-L-D-A measures 0.360" (9.14mm), while TFM-115-32-L-D-A measures 0.435" (11.05mm). This is a mechanical variation within the Tiger Eye™ TFM series and does not affect electrical performance or mating compatibility.

Q: Will the increased insulation height affect PCB layout?

A: The increased insulation height may impact vertical clearance on the PCB. Verify available space above the connector during board design. Both parts maintain identical mating pitch (0.050" / 1.27mm) and row spacing, so horizontal layout compatibility is unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both TFM-115-22-L-D-A and TFM-115-32-L-D-A are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

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

A: Both parts operate across -55°C to 125°C. Verify that this temperature range meets your specific application requirements and that the Liquid Crystal Polymer (LCP) insulation material is suitable for your thermal environment.

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

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