TFM-150-32-SM-D-LC Equivalent & Substitute Parts

Part Overview

The TFM-150-32-SM-D-LC is a surface mount rectangular connector header from Samtec Inc.'s Tiger Eye™ TFM series. This 100-position, dual-row connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board applications with push-pull fastening. The part is Active status and ROHS3 compliant, making it suitable for current production designs. Substitute parts are identified within the same TFM-150 base product family where electrical and mechanical parameters remain compatible with the original design requirements.

• Number of Positions: 100
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Connector Type: Header
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.139" (4.63mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold at 30.0µin (0.76µm)
• Contact Finish - Post: Tin
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Features: Board Lock
• Current Rating: 2.9A per Contact

The primary variable parameter among qualified substitutes is Insulation Height, which differs based on connector configuration code. All substitute parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, qualifying them for current production applications. The TFM-150-32-SM-D-LC and TFM-150-32-S-D-LC share identical insulation height at 0.435" (11.05mm), with the primary difference being the mounting configuration code. The TFM-150-22-S-D-LC provides an intermediate insulation height of 0.360" (9.14mm), while the TFM-150-12-S-D-LC offers the lowest profile at 0.290" (7.37mm). Selection among these substitutes depends on PCB layout constraints and available vertical clearance. All parts maintain equivalent electrical ratings, contact materials, and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can TFM-150-22-S-D-LC be used as a direct replacement for TFM-150-32-SM-D-LC?

A: Electrical compatibility is maintained. The primary difference is insulation height: TFM-150-22-S-D-LC measures 0.360" (9.14mm) versus 0.435" (11.05mm) for the original part. Verify PCB layout and mating connector clearance before substitution.

Q: What is the significance of the insulation height variation?

A: Insulation height determines the vertical profile of the connector assembly. Lower insulation heights reduce overall stack-up height, beneficial for space-constrained applications. All variants maintain identical contact pitch, electrical performance, and current/voltage ratings.

Q: Are all substitute parts surface mount compatible?

A: The TFM-150-32-SM-D-LC and TFM-150-32-S-D-LC are surface mount. The TFM-150-22-S-D-LC and TFM-150-12-S-D-LC are also surface mount. All parts use solder termination for PCB attachment.

Q: Do substitute parts maintain the same contact specifications?

A: Yes. All parts feature 100 positions across 2 rows at 0.050" (1.27mm) pitch, male pin contacts with gold mating finish, phosphor bronze material, and 2.9A per contact current rating.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited). Operating temperature range is -55°C to 125°C across all variants.
