Substitute Part Grouping Explanation

The TFM-150-22-L-D-A qualifies as a direct substitute for the TFM-150-32-L-D based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFM
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 100
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

Differing Parameters:

• Insulation Height: TFM-150-32-L-D is 0.435" (11.05mm); TFM-150-22-L-D-A is 0.360" (9.14mm)
• Features: TFM-150-22-L-D-A includes Board Guide feature

The variation in insulation height and the addition of a board guide in the substitute part represent mechanical design differences that do not affect electrical performance or mating compatibility when the connector pitch and contact specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-150-32-L-D and TFM-150-22-L-D-A are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts depends on mechanical fit requirements within the application:

• TFM-150-32-L-D is suitable for applications requiring an insulation height of 0.435" (11.05mm) without board guide features.
• TFM-150-22-L-D-A is suitable for applications requiring an insulation height of 0.360" (9.14mm) with integrated board guide alignment features.

Both parts maintain identical current and voltage ratings, operating temperature ranges, and contact specifications. The choice between these variants is determined by PCB layout constraints and mechanical assembly requirements rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TFM-150-22-L-D-A be used as a direct replacement for TFM-150-32-L-D?

A: Yes, provided that the application accommodates the reduced insulation height of 0.360" (9.14mm) versus 0.435" (11.05mm), and the board guide feature does not conflict with the PCB design. All electrical parameters, contact specifications, and mating pitch remain identical.

Q: What is the significance of the board guide feature in the TFM-150-22-L-D-A?

A: The board guide is a mechanical alignment feature that assists in proper connector positioning during assembly. It does not affect electrical performance or mating compatibility.

Q: Are both parts RoHS compliant?

A: Yes, both TFM-150-32-L-D and TFM-150-22-L-D-A are ROHS3 compliant.

Q: Do these connectors have the same current and voltage ratings?

A: Yes, both parts are rated for 2.9A per contact and 275VAC, with identical operating temperature ranges of -55°C to 125°C.

Q: What is the pitch specification for these connectors?

A: Both connectors feature a mating pitch of 0.050" (1.27mm) with row spacing of 0.050" (1.27mm), maintaining 100 positions across 2 rows.

Q: Are there any differences in contact material or finish?

A: No, both parts use phosphor bronze contacts with gold mating finish and tin post finish, ensuring identical contact performance and reliability.
