SFMC-102-L1-L-D Equivalent & Substitute Parts

Part Overview

The SFMC-102-L1-L-D is a 4-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFMC series, designed for board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating with through-hole solder termination and gold-plated mating contacts. The part is currently active in production with 1010 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, enabling direct replacement in applications where the original part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFMC-102-L1-L-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 4 positions in 2 rows
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Contact Interface: Gold-plated mating surface with 10.0µin (0.25µm) thickness
• Electrical Performance: 2.9A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Range: -55°C to 125°C temperature specification

The SFMC-102-01-L-D meets all these criteria and is classified as a direct substitute. Both parts share the same base product number (SFMC-102) and Tiger Eye™ SFMC series designation, confirming mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-102-L1-L-D and SFMC-102-01-L-D are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. The SFMC-102-01-L-D currently has higher stock availability (2480 units) compared to the SFMC-102-L1-L-D (1010 units). Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory equivalence for applications requiring these standards. The identical contact configuration, pitch specifications, and current ratings guarantee direct functional interchangeability in board-to-board and cable connector applications.

Frequently Asked Questions (FAQ)

Q: Can SFMC-102-01-L-D be used as a direct replacement for SFMC-102-L1-L-D?

A: Yes. Both parts are identical in all critical electrical and mechanical parameters, including connector type, position count, pitch, mounting method, contact finish, current rating, and operating temperature range. They are fully interchangeable.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: connector type (receptacle), number of positions (4), mating pitch (0.050"), row spacing (0.050"), mounting type (through-hole), termination method (solder), contact finish (gold), current rating (2.9A per contact), operating temperature range (-55°C to 125°C), and flammability rating (UL94 V-0).

Q: Are there any differences in compliance or certification between these parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The SFMC-102-01-L-D has documented REACH Unaffected status and MSL 1 (Unlimited) rating, while the SFMC-102-L1-L-D lists MSL as Not Applicable. These differences do not affect functional interchangeability.

Q: What is the difference between the part numbers SFMC-102-L1-L-D and SFMC-102-01-L-D?

A: The part numbers differ in their suffix designations (L1 versus 01), but both share the same base product number (SFMC-102) and Tiger Eye™ SFMC series. The suffix variation indicates different manufacturing or packaging configurations within the same product family, but electrical and mechanical specifications remain identical.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C, making them suitable for industrial and automotive applications within this temperature range.

Q: What is the current-carrying capacity of these connectors?

A: Each contact is rated for 2.9A. With 4 positions, the total connector current capacity is 11.6A when all contacts are fully loaded.
