Substitute Part Grouping Explanation

Substitution of the SFM-106-02-S-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 12 positions in 2-row configuration
• Pitch Specification: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Electrical Performance: 3.2A per contact at 250VAC minimum
• Contact Material & Finish: Beryllium copper with gold mating surface (30.0µin thickness)
• Temperature Range: -55°C to 125°C operating envelope
• Compliance: ROHS3 and UL94 V-0 flammability rating

The substitute part SFM-106-02-S-D-A maintains identical electrical, mechanical, and environmental specifications. Variations in secondary features such as board guide presence do not affect core substitution eligibility when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-106-02-S-D and SFM-106-02-S-D-A are Active status products from Samtec Inc. and maintain full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts should be based on PCB design requirements:

• SFM-106-02-S-D: Standard configuration without board guide feature. Use when PCB layout accommodates self-alignment or when board guide is not required for assembly process.

• SFM-106-02-S-D-A: Includes board guide feature for enhanced alignment during mating operations. Use when automated assembly processes or tight tolerance requirements necessitate positive positioning guidance.

Both parts are electrically and mechanically interchangeable for applications within the specified 3.2A per contact, 250VAC operating envelope and -55°C to 125°C temperature range. Inventory availability should be evaluated based on current supply chain status.

Frequently Asked Questions (FAQ)

Q: Are SFM-106-02-S-D and SFM-106-02-S-D-A fully interchangeable?

A: Yes, both parts are electrically and mechanically equivalent. They share identical contact configurations, pitch specifications, current and voltage ratings, and operating temperature ranges. The board guide feature in the SFM-106-02-S-D-A is an additive feature that does not affect substitution eligibility.

Q: What is the significance of the board guide feature in SFM-106-02-S-D-A?

A: The board guide provides mechanical alignment assistance during connector mating. This feature is beneficial for high-volume automated assembly but does not alter electrical performance or contact integrity.

Q: Can these connectors be used in applications requiring temperatures below -55°C or above 125°C?

A: No. Both parts are rated for -55°C to 125°C operation. Applications outside this range require alternative connector selection.

Q: What is the maximum current capacity per contact?

A: Both parts are rated for 3.2A per contact at 250VAC. Total system current must account for the number of loaded positions and thermal management considerations.

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

A: Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements. Moisture sensitivity level is 1 (Unlimited), indicating no special storage or handling requirements. Suitability for specific high-reliability applications depends on additional qualification requirements beyond these specifications.

Q: What is the mating pitch, and why is it critical for substitution?

A: The mating pitch is 0.050" (1.27mm), which defines the center-to-center distance between contacts. This parameter is critical for substitution because connectors with different pitches are mechanically incompatible and cannot mate with the same plug connector.

Q: Can the SFM-106-02-S-D be used as a plug connector?

A: No. The SFM-106-02-S-D is a receptacle connector with female socket contacts. It is designed to receive a mating plug connector with male pin contacts from the same series.
