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

Part Overview

The Samtec TFM-150-32-SM-D is a surface mount rectangular connector header from the Tiger Eye™ TFM series. This connector features 100 positions arranged in 2 rows with 0.050" (1.27mm) pitch, designed for board-to-board applications. The part is active in production with full inventory availability. Substitute parts are identified based on shared electrical specifications, mechanical compatibility within the TFM series, and identical core performance parameters. Alternative models accommodate different insulation heights and fastening mechanisms while maintaining connector functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TFM-150 series is determined by the following criteria:

Invariant Parameters (Must Match):

• 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
• Termination: Solder
• Current rating: 2.9A per Contact
• Voltage rating: 275VAC
• Operating temperature: -55°C ~ 125°C
• Contact finish - Mating: Gold
• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameters (Differentiate Substitutes):

• Insulation height: 0.290" (7.37mm), 0.360" (9.14mm), or 0.435" (11.05mm)
• Fastening type: Push-Pull (main part) or alternative mechanisms
• Features: Board Guide, Board Lock, or none

The five substitute parts maintain all invariant parameters while offering different insulation heights and fastening features to accommodate specific board layout and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between the main part TFM-150-32-SM-D and its substitutes depends on board design requirements:

Insulation Height Selection:

• 0.290" (7.37mm): Minimum profile applications (TFM-150-12-S-D-LC)
• 0.360" (9.14mm): Mid-range profile applications (TFM-150-22-S-D-LC, TFM-150-22-S-D-A)
• 0.435" (11.05mm): Standard profile applications (TFM-150-32-SM-D, TFM-150-32-S-D-A, TFM-150-32-S-D-LC)

Fastening Mechanism Selection:

• Push-Pull: Original fastening type (TFM-150-32-SM-D)
• Board Lock: Mechanical locking feature (TFM-150-12-S-D-LC, TFM-150-22-S-D-LC, TFM-150-32-S-D-LC)
• Board Guide: Alignment guide feature (TFM-150-22-S-D-A, TFM-150-32-S-D-A)

All parts share identical electrical performance, temperature ratings, and compliance certifications. Inventory availability ranges from 985 to 3096 pieces across all options.

Frequently Asked Questions (FAQ)

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

A: Yes, within design constraints. Both parts share identical electrical specifications, current rating (2.9A per contact), voltage rating (275VAC), operating temperature range (-55°C to 125°C), and insulation height (0.435"). The primary difference is the fastening mechanism: TFM-150-32-SM-D uses Push-Pull fastening, while TFM-150-32-S-D-LC uses Board Lock. Board layout and mechanical assembly requirements determine compatibility.

Q: What is the significance of insulation height variation in the TFM-150 series?

A: Insulation height determines the vertical profile of the connector assembly. The three available heights (0.290", 0.360", 0.435") accommodate different PCB stackup configurations and available board space. Selection is driven by mechanical clearance requirements, not electrical performance, as all variants maintain identical electrical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including TFM-150-32-SM-D and the five alternatives, are ROHS3 compliant with moisture sensitivity level 1 (unlimited). Compliance certifications are identical across the entire substitution group.

Q: What distinguishes Board Lock from Board Guide features?

A: Board Lock (LC designation) provides mechanical locking engagement with the mating connector. Board Guide (A designation) provides alignment guidance without locking. The main part TFM-150-32-SM-D uses Push-Pull fastening. Feature selection depends on assembly process requirements and mating connector specifications.

Q: Can parts with different insulation heights be mixed in the same assembly?

A: Insulation height is a mechanical parameter that affects connector profile and board spacing. Mixing different heights in a single assembly is not recommended unless the application specifically accommodates variable stacking heights. Verify board layout compatibility before combining parts with different insulation heights.
