Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFM-105 base product family is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters (Non-Negotiable):

• Number of Positions: 10
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Current Rating: 3.2A per Contact
• Voltage Rating: 250VAC
• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 10.0µin (0.25µm)

Core Mechanical Parameters (Non-Negotiable):

• Connector Type: Receptacle
• Contact Type: Female Socket
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Liquid Crystal Polymer (LCP)
• Insulation Height: 0.185" (4.70mm)
• Contact Shape: Square
• Contact Material: Beryllium Copper

Compliance & Environmental Parameters (Non-Negotiable):

• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed Differences):

• Features: Board Guide and Pick and Place capabilities may be present or absent

The three substitute parts (SFM-105-02-L-D-A-K-TR, SFM-105-02-L-D-A-P-TR, SFM-105-02-L-D-K-TR) maintain identical electrical and mechanical specifications to the main part SFM-105-L2-L-D-TR. Differences exist only in optional assembly features (Board Guide presence, Pick and Place capability) which do not affect core connector functionality or mating compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability in applications requiring 10-position, 0.050" pitch surface mount receptacle connectors with gold-plated contacts and push-pull fastening.

Selection Criteria Based on Provided Parameters:

All substitute parts maintain Active product status and ROHS3 compliance, matching the primary part's regulatory standing. The SFM-105-02-L-D-A-K-TR and SFM-105-02-L-D-A-P-TR include Board Guide and Pick and Place features, which provide assembly process advantages without altering electrical or mechanical performance. The SFM-105-02-L-D-K-TR includes Pick and Place capability without Board Guide integration.

Selection between these parts depends on manufacturing process requirements and assembly equipment compatibility. All parts are suitable for applications operating within the -55°C to 125°C temperature range at 250VAC with 3.2A per contact current requirements.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. All four parts share identical electrical specifications: 10 positions, 0.050" (1.27mm) pitch, 3.2A per contact current rating, 250VAC voltage rating, and gold-plated mating contacts with 10.0µin (0.25µm) finish thickness.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in optional assembly features. SFM-105-02-L-D-A-K-TR and SFM-105-02-L-D-A-P-TR include Board Guide and Pick and Place capabilities. SFM-105-02-L-D-K-TR includes Pick and Place only. These features do not affect connector mating or electrical performance.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your PCB layout accommodates the optional features present on substitute parts. Board Guide and Pick and Place features do not interfere with standard connector mating or solder termination.

Q: Are all parts ROHS3 compliant?

A: Yes. All four parts maintain ROHS3 compliance and UL94 V-0 flammability rating.

Q: What is the operating temperature range for these connectors?

A: All parts operate across -55°C to 125°C, suitable for industrial and commercial applications.

Q: Do these parts have different moisture sensitivity requirements?

A: No. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, requiring no special handling or baking procedures.

Q: Which part should I select for automated assembly?

A: SFM-105-02-L-D-A-K-TR and SFM-105-02-L-D-A-P-TR include Pick and Place features optimized for automated assembly equipment. SFM-105-02-L-D-K-TR provides Pick and Place capability without Board Guide integration.
