Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFMC-104-02-SM-D are identified based on strict equivalence across the following critical parameters:

• Number of Positions: 8
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Contact Type: Female Socket
• Contact Material: Beryllium Copper
• Contact Finish - Mating: Gold, 30.0µin (0.76µm)
• Current Rating: 2.9A per Contact
• Operating Temperature: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The two identified substitutes, SFMC-104-02-S-D and SFMC-104-L2-S-D, maintain identical electrical and mechanical specifications. Differences in part numbering reflect variations in fastening or contact post configurations that do not affect core connector functionality within the Tiger Eye™ SFMC series.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFMC-104-02-SM-D, SFMC-104-02-S-D, and SFMC-104-L2-S-D—are active production components from Samtec Inc. with identical electrical and mechanical specifications. Selection among these parts should be based on:

• Availability: SFMC-104-02-SM-D has the highest inventory at 1,051 units, followed by SFMC-104-02-S-D at 907 units and SFMC-104-L2-S-D at 845 units.
• Compliance: All three parts meet ROHS3 compliance and UL94 V-0 flammability requirements.
• Regulatory: All parts carry EAR99 ECCN classification and identical HTSUS codes (8536.69.4040).

For applications requiring immediate availability, SFMC-104-02-SM-D is the primary choice. SFMC-104-02-S-D and SFMC-104-L2-S-D serve as equivalent alternatives when the primary part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can SFMC-104-02-S-D and SFMC-104-L2-S-D be used interchangeably with SFMC-104-02-SM-D?

A: Yes. All three parts share identical electrical and mechanical parameters including connector pitch, position count, contact material, current rating, and operating temperature range. They are functionally equivalent within the Tiger Eye™ SFMC series.

Q: What determines substitutability for SFMC-104 series connectors?

A: Substitutability is determined by equivalence in the following parameters: number of positions (8), mating pitch (0.050"), row configuration (2 rows at 0.050" spacing), mounting type (surface mount), contact material (beryllium copper), contact finish (gold at 30.0µin), current rating (2.9A per contact), and operating temperature range (-55°C to 125°C).

Q: Are there any differences in packaging or handling between these three parts?

A: All three parts are supplied in tube packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special storage or handling requirements.

Q: Do all three parts comply with environmental regulations?

A: Yes. All parts are ROHS3 compliant and carry REACH Unaffected status (where specified). They meet UL94 V-0 flammability requirements.

Q: Which part should be selected for new designs?

A: For new designs, any of the three parts may be selected based on availability and supply chain considerations. All maintain active production status and identical performance specifications.
