Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFMC-118-L2-S-D are identified based on strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (36)
• Pitch specification (0.050" / 1.27mm mating pitch)
• Row configuration (2 rows with 0.050" row spacing)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold-plated beryllium copper)
• Current rating (2.9A per contact)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (UL94 V-0, ROHS3)
• Moisture sensitivity level (MSL 1)

The SFMC-118-02-S-D qualifies as a direct substitute because it maintains identical specifications across all these parameters while remaining within the same Tiger Eye™ SFMC product series.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-118-L2-S-D and SFMC-118-02-S-D are active production parts with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and procurement requirements:

• SFMC-118-L2-S-D: 990 units in stock
• SFMC-118-02-S-D: 1011 units in stock

Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040. Either part is suitable for direct substitution in applications requiring 36-position, 0.050" pitch surface mount receptacle connectors with gold-plated contacts and 2.9A per contact current rating across the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SFMC-118-02-S-D be used as a direct replacement for SFMC-118-L2-S-D?

A: Yes. Both parts are identical across all electrical, mechanical, and compliance parameters. They share the same base product number (SFMC-118), connector configuration (36-position, 2-row, 0.050" pitch), contact specifications (gold-plated beryllium copper, 2.9A rating), and certifications (ROHS3, UL94 V-0, MSL 1).

Q: Are there differences in mating compatibility between these parts?

A: No. Both receptacles feature identical 0.050" (1.27mm) mating pitch and 0.050" row spacing, ensuring full mechanical and electrical compatibility with the same plug connectors.

Q: What is the significance of the different part number suffixes (L2 vs. 02)?

A: The suffixes indicate internal Samtec product variants within the Tiger Eye™ SFMC series. Both variants maintain identical specifications for the parameters that determine connector functionality and substitutability.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance. Both operate across -55°C to 125°C and carry MSL 1 rating. Selection should be based on specific application requirements and qualification documentation.

Q: What is the current rating per contact for these connectors?

A: Both parts are rated at 2.9A per contact, supporting applications requiring this current capacity across the full operating temperature range.

Q: Are there any packaging or handling differences?

A: Both parts are supplied in tube packaging with MSL 1 (Unlimited) moisture sensitivity, indicating standard handling and storage conditions without special moisture control requirements.
