Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFM-105-L1-L-D are qualified based on strict electrical and mechanical parameter matching within the Tiger Eye™ SFM series. All substitute parts maintain identical core specifications:

Critical Matching Parameters:

• Connector type: Receptacle
• Number of positions: 10
• Pitch - mating: 0.050" (1.27mm)
• Number of rows: 2
• Row spacing - mating: 0.050" (1.27mm)
• Mounting type: Through Hole
• Termination: Solder
• Current rating: 3.2A per Contact
• Voltage rating: 250VAC
• Operating temperature: -55°C ~ 125°C
• Contact finish - mating: Gold (10.0µin / 0.25µm)
• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant

Substitute parts differ only in optional features (board guide, mounting flange, mounting hardware, board lock) and moisture sensitivity level designations. These variations do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the SFM-105-L1-L-D. Selection between equivalent parts should be based on:

Feature Requirements: SFM-105-01-L-D-A includes a board guide feature for enhanced alignment during mating. SFM-105-01-L-D-DS provides mounting flange and mounting hardware for panel or chassis integration. SFM-105-01-L-D-LC incorporates a board lock feature for secure retention.

Compliance Status: All parts are ROHS3 compliant and UL94 V-0 rated. SFM-105-01-L-D-DS is REACH Affected; all other variants are REACH Unaffected.

Moisture Sensitivity: SFM-105-L1-L-D and SFM-105-01-L-D-DS are designated as Not Applicable for MSL. SFM-105-01-L-D, SFM-105-01-L-D-A, and SFM-105-01-L-D-LC are rated MSL 1 (Unlimited).

Inventory Availability: SFM-105-01-L-D-A offers the highest current inventory at 2150 units.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically interchangeable with the SFM-105-L1-L-D?

A: Yes. All substitute parts maintain identical electrical specifications including current rating (3.2A per contact), voltage rating (250VAC), operating temperature range (-55°C ~ 125°C), and contact finish (gold, 10.0µin / 0.25µm).

Q: What is the difference between the substitute part variants?

A: Substitute parts differ only in optional mechanical features and moisture sensitivity designations. SFM-105-01-L-D-A adds a board guide for alignment. SFM-105-01-L-D-DS includes mounting flange and hardware. SFM-105-01-L-D-LC provides a board lock feature. SFM-105-01-L-D is the base variant without additional features.

Q: Can I use SFM-105-01-L-D-DS if my application requires REACH compliance?

A: SFM-105-01-L-D-DS is REACH Affected. If REACH Unaffected status is required, select from SFM-105-01-L-D, SFM-105-01-L-D-A, or SFM-105-01-L-D-LC.

Q: Do the substitute parts have the same mating pitch and row spacing?

A: Yes. All substitute parts maintain 0.050" (1.27mm) pitch mating and 0.050" (1.27mm) row spacing, ensuring mechanical compatibility with existing mating connectors.

Q: What is the significance of MSL rating differences?

A: SFM-105-L1-L-D and SFM-105-01-L-D-DS are designated MSL Not Applicable. SFM-105-01-L-D, SFM-105-01-L-D-A, and SFM-105-01-L-D-LC are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are all parts suitable for through-hole PCB assembly?

A: Yes. All parts are through-hole mounted with solder termination, suitable for standard PCB assembly processes.
