SFM-150-02-SM-D-LC Equivalent & Substitute Parts

Part Overview

The SFM-150-02-SM-D-LC is a 100-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for surface mount applications with 0.050" (1.27mm) pitch. This board-to-board or cable connector features gold-plated mating contacts and push-pull fastening. The part is Active status and widely used in high-density interconnect applications requiring reliable electrical performance across industrial temperature ranges.

Substitute parts are identified when design requirements allow flexibility in specific connector variants while maintaining core electrical and mechanical compatibility within the SFM-150 base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFM-150 family is determined by the following critical parameters that must remain constant:

• Base product number (SFM-150)
• Number of positions (100)
• Pitch - mating (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing - mating (0.050" / 1.27mm)
• Connector type (Receptacle)
• Contact type (Female Socket)
• Mounting type (Surface Mount)
• Termination (Solder)
• Current rating (3.2A per Contact)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish - mating (Gold)
• Insulation material (LCP)
• Flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)
• MSL rating (1)

The identified substitutes differ only in specific connector variant codes within the part number designation, which reflect internal design variations that do not affect electrical or mechanical compatibility for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical electrical and mechanical specifications across all critical parameters. Selection between SFM-150-02-SM-D-LC, SFM-150-02-S-D-LC, and SFM-150-L2-S-D-LC is based on product availability and supply chain considerations rather than functional differences.

All substitute parts carry Active product status and maintain full ROHS3 compliance and UL94 V-0 flammability certification. Moisture sensitivity level remains constant at MSL 1 (Unlimited) across all variants, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can SFM-150-02-S-D-LC be used as a direct replacement for SFM-150-02-SM-D-LC?

A: Yes. Both parts share identical electrical ratings (3.2A per contact, 250VAC), mechanical dimensions (100 positions, 0.050" pitch, 2 rows), contact materials (beryllium copper with gold finish), and operating temperature range (-55°C ~ 125°C). The part number variants reflect internal design differences that do not affect functional compatibility.

Q: What is the difference between SFM-150-L2-S-D-LC and the other variants?

A: SFM-150-L2-S-D-LC maintains all critical electrical and mechanical parameters identical to SFM-150-02-SM-D-LC and SFM-150-02-S-D-LC. The variant designation in the part number does not indicate functional differences relevant to standard connector applications.

Q: Are all three parts suitable for the same PCB layout and footprint?

A: All three parts share identical mating pitch (0.050"), row spacing (0.050"), insulation height (0.185"), and surface mount termination. PCB footprints designed for one variant are compatible with the others.

Q: Do these parts require different handling or storage procedures?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity and storage requirements. No special desiccant or controlled environment storage is necessary.

Q: Are all variants ROHS3 compliant?

A: Yes. SFM-150-02-SM-D-LC, SFM-150-02-S-D-LC, and SFM-150-L2-S-D-LC all meet ROHS3 compliance requirements.
