Substitute Part Grouping Explanation

The TFM-105-02-L-D-A-P has one qualified substitute within the Tiger Eye™ TFM series: TFM-105-02-L-D-A-K. Substitution is valid based on the following criteria:

Critical Parameters for Substitution:

• Identical number of positions (10) and row configuration (2 rows)
• Identical mating pitch (0.050" / 1.27mm)
• Identical connector type (Header), contact type (Male Pin), and mounting type (Surface Mount)
• Identical electrical ratings: 2.9A per contact, 275VAC
• Identical operating temperature range (-55°C ~ 125°C)
• Identical material specifications: Phosphor Bronze contacts, Liquid Crystal Polymer insulation
• Identical contact finish specifications: Gold mating surface, Tin post finish
• Identical compliance: ROHS3 Compliant, UL94 V-0 flammability rating

The substitute part maintains full functional and mechanical compatibility with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-105-02-L-D-A-P and TFM-105-02-L-D-A-K are active production parts with identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on:

Availability: TFM-105-02-L-D-A-K currently has higher inventory (1072 units) compared to TFM-105-02-L-D-A-P (972 units), making it suitable for applications with extended procurement timelines or high-volume requirements.

Compliance: Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements, suitable for regulated applications.

Regulatory Classification: Both parts carry EAR99 export classification and are REACH unaffected, with identical HTSUS commodity codes.

Either part is functionally interchangeable in applications requiring 10-position, 2-row surface mount headers with 0.050" pitch, 2.9A per contact current rating, and 275VAC voltage rating.

Frequently Asked Questions (FAQ)

Q: Are TFM-105-02-L-D-A-P and TFM-105-02-L-D-A-K mechanically interchangeable?

A: Yes. Both parts have identical mechanical dimensions, mounting footprints, and contact configurations. They can be used interchangeably in PCB designs without layout modifications.

Q: What determines if a part can substitute for TFM-105-02-L-D-A-P?

A: Substitution requires matching specifications across: number of positions and rows, mating pitch, connector and contact type, mounting method, electrical ratings (current and voltage), operating temperature range, contact materials and finishes, insulation material, and compliance certifications.

Q: Do both parts have the same electrical performance?

A: Yes. Both parts have identical current ratings (2.9A per contact) and voltage ratings (275VAC), with the same contact material (Phosphor Bronze) and finish specifications.

Q: Are there any differences in packaging or handling?

A: Both parts are supplied in tube packaging with MSL 1 (Unlimited) moisture sensitivity level, requiring no special storage conditions.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C, suitable for industrial and automotive applications within this range.

Q: What is the difference between the "P" and "K" designations in the part numbers?

A: The provided data does not specify the technical distinction between these designations. Both parts are functionally equivalent across all documented electrical and mechanical parameters.
