Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-110-L2-S-D-A-P is determined by strict alignment of the following critical parameters:

• Connector Configuration: 20-position receptacle with 2 rows at 0.050" (1.27mm) pitch and row spacing
• Mounting and Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Interface: Female socket with gold mating finish
• Insulation Material: Liquid Crystal Polymer (LCP)
• Compliance: ROHS3 compliant with MSL 1 rating

The substitute part 5-104652-2 from TE Connectivity AMP Connectors meets these core electrical and mechanical requirements, enabling direct functional replacement in applications where the SFM-110-L2-S-D-A-P is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-110-L2-S-D-A-P and 5-104652-2 are active products with ROHS3 compliance and MSL 1 ratings, confirming suitability for current manufacturing and long-term storage without moisture sensitivity constraints. Selection between these parts should be based on:

• Supply Availability: The SFM-110-L2-S-D-A-P has 664 units in stock; the 5-104652-2 has 270,465 units available, providing significant supply chain flexibility.
• Series Compatibility: The SFM-110-L2-S-D-A-P belongs to Samtec's Tiger Eye™ SFM series; the 5-104652-2 belongs to TE Connectivity's AMPMODU 50/50 Grid series. Both series are established connector families with documented mating interfaces.
• Mechanical Features: The SFM-110-L2-S-D-A-P includes board guide and pick-and-place features; the 5-104652-2 includes board lock features. These design differences do not affect electrical substitution but may influence PCB layout considerations.
• Operating Temperature Range: The SFM-110-L2-S-D-A-P operates -55°C to 125°C; the 5-104652-2 operates -65°C to 105°C. Application thermal requirements should guide selection.

Frequently Asked Questions (FAQ)

Q: Can the 5-104652-2 directly replace the SFM-110-L2-S-D-A-P in existing designs?

A: Yes, provided the mating connector is compatible with the AMPMODU 50/50 Grid series. Both connectors share identical pitch (0.050"), row configuration (2 rows), position count (20), contact type (female socket), and gold mating finish. Mechanical features differ (board guide vs. board lock), but these do not affect electrical compatibility.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Manufacturer series—Tiger Eye™ SFM vs. AMPMODU 50/50 Grid; (2) Operating temperature range—SFM-110-L2-S-D-A-P extends to -55°C minimum and 125°C maximum, while 5-104652-2 operates -65°C to 105°C; (3) Mechanical features—board guide/pick-and-place vs. board lock; (4) Mated stacking heights vary between series. Electrical performance and contact specifications are equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both the SFM-110-L2-S-D-A-P and 5-104652-2 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), suitable for standard manufacturing and storage environments.

Q: What is the significance of the 0.050" (1.27mm) pitch specification?

A: The 0.050" pitch defines the center-to-center distance between adjacent contacts and between rows. This specification is critical for mechanical and electrical compatibility with mating connectors. Both substitute parts maintain this pitch, ensuring interchangeability with compatible plug connectors.

Q: Can I use these connectors interchangeably if my design uses a specific mating connector?

A: Substitution is valid only if the mating connector is compatible with both the SFM series and AMPMODU 50/50 Grid series. Verify mating connector compatibility with both manufacturers' documentation before implementing substitution in production designs.
