Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFMC-110-L1-S-D are identified based on strict electrical and mechanical parameter equivalence within the Tiger Eye™ SFMC series. The following parameters define substitution eligibility:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (20)
• Pitch - mating (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Through Hole)
• Termination (Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Contact finish thickness - mating (30.0µin / 0.76µm)
• Insulation material (Liquid Crystal Polymer)
• Insulation height (0.180" / 4.57mm)
• Contact length - post (0.120" / 3.05mm)
• Contact shape (Square)
• Current rating (2.9A per Contact)
• Operating temperature (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS status (ROHS3 Compliant)

Substitute parts SFMC-110-01-S-D and SFMC-110-T1-S-D meet all critical electrical and mechanical parameters. Variations in contact material and moisture sensitivity level do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFMC-110-L1-S-D, SFMC-110-01-S-D, and SFMC-110-T1-S-D—maintain active product status and full ROHS3 compliance. Selection between these parts should be based on inventory availability and contact material requirements.

SFMC-110-01-S-D and SFMC-110-T1-S-D offer higher inventory levels (1382 and 1504 units respectively) compared to SFMC-110-L1-S-D (701 units), supporting supply chain continuity for high-volume applications. The primary technical distinction is contact material: SFMC-110-L1-S-D and SFMC-110-01-S-D use Beryllium Copper contacts, while SFMC-110-T1-S-D uses Phosphor Bronze contacts. Both contact materials deliver equivalent electrical performance at the specified 2.9A per contact current rating and maintain identical mechanical and thermal specifications.

SFMC-110-01-S-D carries MSL 1 (Unlimited) rating, suitable for applications with extended storage or high-humidity environments. SFMC-110-L1-S-D and SFMC-110-T1-S-D are not subject to moisture sensitivity limitations.

Frequently Asked Questions (FAQ)

Q: Are SFMC-110-L1-S-D, SFMC-110-01-S-D, and SFMC-110-T1-S-D mechanically interchangeable?

A: Yes. All three parts share identical mechanical dimensions, mounting specifications, and connector geometry. They are direct mechanical substitutes within the Tiger Eye™ SFMC series.

Q: What is the difference between Beryllium Copper and Phosphor Bronze contacts?

A: Both materials meet the specified 2.9A per contact current rating and -55°C to 125°C operating temperature range. Contact material selection does not affect electrical performance for standard applications within these parameters.

Q: Does moisture sensitivity level affect part selection?

A: Moisture sensitivity level (MSL) applies to storage and handling conditions. SFMC-110-01-S-D (MSL 1 - Unlimited) is suitable for extended storage without baking requirements. SFMC-110-L1-S-D and SFMC-110-T1-S-D are not subject to MSL restrictions. Selection depends on supply chain and storage protocols.

Q: Can I substitute these parts on existing PCB designs?

A: Yes. All three parts are pin-compatible with identical pitch (0.050"), row spacing (0.050"), insulation height (0.180"), and contact post length (0.120"). No PCB layout modifications are required.

Q: Which part should I select for new designs?

A: Selection should prioritize inventory availability and supply chain requirements. SFMC-110-01-S-D and SFMC-110-T1-S-D offer higher stock levels. Contact material choice (Beryllium Copper vs. Phosphor Bronze) does not affect performance within specified electrical and thermal parameters.

Q: Are all three parts RoHS compliant?

A: Yes. SFMC-110-L1-S-D, SFMC-110-01-S-D, and SFMC-110-T1-S-D are all ROHS3 compliant and maintain UL94 V-0 flammability rating.
