Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TFM-107-02-S-S-WT-P-TR is determined by strict alignment of the following critical parameters:

• Position Count and Pitch: 7 positions at 0.050" (1.27mm) mating pitch
• Connector Topology: Header type with male pin contacts
• Mounting Configuration: Surface mount with solder termination
• Mechanical Interface: Shrouded 4-wall construction with push-pull fastening
• Electrical Performance: 2.9A per contact at 275VAC rating
• Environmental Compliance: UL94 V-0 flammability, RoHS3 compliance, MSL Level 1
• Thermal Range: -55°C to 125°C operating temperature
• Contact Materials and Finishes: Phosphor bronze with gold mating finish and tin post finish

Only parts meeting all these specifications qualify as direct substitutes. Deviations in position count, pitch, mounting type, shrouding configuration, or electrical ratings preclude substitution.

Engineering Selection Recommendations

The TFM-107-02-S-S-WT-P-TR maintains Active product status with full availability and established supply chain presence. Selection of this connector is supported by:

• Regulatory Compliance: UL94 V-0 flammability rating and ROHS3 compliance satisfy industrial and commercial regulatory requirements
• Environmental Qualification: MSL Level 1 rating eliminates moisture sensitivity constraints during storage and handling
• Thermal Performance: Operating range of -55°C to 125°C accommodates extended environmental conditions
• Electrical Specifications: 2.9A per contact and 275VAC rating provide adequate capacity for standard signal and power distribution applications
• Manufacturing Continuity: Active status ensures ongoing production and supply availability

No alternative part numbers are required for this specification, as the substitute listing reflects the identical part number.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the TFM-107-02-S-S-WT-P-TR?

A: Direct substitution requires matching all critical parameters: 7-position configuration, 0.050" (1.27mm) pitch, surface mount solder termination, shrouded 4-wall construction, push-pull fastening, 2.9A per contact rating, 275VAC voltage rating, and identical contact materials and finishes. Deviations in any of these parameters preclude substitution.

Q: Does the Tape & Reel packaging affect substitution compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The TR (Tape & Reel) packaging is a supply format specification. Connectors supplied in alternative packaging formats (bulk, tube, or tray) with identical part specifications remain functionally equivalent.

Q: What is the significance of the MSL Level 1 rating?

A: MSL Level 1 indicates unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and reduces handling constraints compared to higher MSL levels.

Q: Are there position count variations within the TFM series that could serve as alternatives?

A: No. The 7-position specification is integral to the TFM-107-02-S-S-WT-P-TR design. Different position counts (such as 2, 3, 4, 5, 6, 8, or 10 positions) represent distinct part numbers within the TFM series and are not substitutable due to PCB footprint and mating interface incompatibility.

Q: How does the 0.050" pitch specification limit substitution options?

A: The 1.27mm (0.050") pitch is a fundamental mechanical parameter that determines PCB layout, mating connector design, and contact spacing. Only connectors with identical pitch specifications can mate with existing receptacles or cable assemblies designed for this part.
