Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFM-110-T1-S-D are identified based on electrical and mechanical compatibility within the Tiger Eye™ SFM series. The following parameters determine substitution eligibility:

• Connector type: Receptacle
• 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
• Contact finish - mating: Gold
• Current rating: 3.2A per contact
• Voltage rating: 250VAC
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The identified substitutes maintain these core parameters while differing in minor design features such as board guide configuration and moisture sensitivity level classification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-110-T1-S-D, SFM-110-01-S-D, and SFM-110-01-S-D-A—are active products from Samtec Inc. and maintain full ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on specific application requirements:

SFM-110-T1-S-D is the primary part specification with 723 units in stock.

SFM-110-01-S-D is a direct electrical and mechanical equivalent with 765 units in stock, differing only in moisture sensitivity level classification (1 - Unlimited versus Not Applicable).

SFM-110-01-S-D-A includes a board guide feature and is available with 705 units in stock. This variant is suitable for applications requiring additional mechanical alignment during mating.

All parts share identical electrical ratings (3.2A per contact, 250VAC), thermal performance (-55°C ~ 125°C), and contact finish specifications (gold mating surface, 30.0µin thickness).

Frequently Asked Questions (FAQ)

Q: Can SFM-110-01-S-D be used as a direct replacement for SFM-110-T1-S-D?

A: Yes. Both parts maintain identical electrical and mechanical parameters including connector type, position count, pitch, row spacing, mounting type, contact finish, current rating, voltage rating, and operating temperature range. The difference in moisture sensitivity level classification does not affect electrical or mechanical compatibility.

Q: What is the functional difference between SFM-110-01-S-D and SFM-110-01-S-D-A?

A: SFM-110-01-S-D-A includes a board guide feature. This provides additional mechanical alignment support during connector mating. All other electrical and mechanical parameters remain identical between the two parts.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts share identical pitch (0.050"), row spacing (0.050"), insulation height (0.180"), and contact length specifications. PCB footprints designed for any of these parts are compatible with the others.

Q: What does the moisture sensitivity level difference indicate?

A: SFM-110-T1-S-D is classified as Not Applicable for moisture sensitivity level, while SFM-110-01-S-D and SFM-110-01-S-D-A are classified as MSL 1 (Unlimited). This classification relates to component storage and handling requirements prior to assembly, not to operational performance.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS code (8536.69.4040). All maintain UL94 V-0 material flammability rating.

Q: What is the current rating per contact for these connectors?

A: All three parts are rated for 3.2A per contact at 250VAC maximum voltage.
