Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFML-145-L1-S-D is based on strict electrical and mechanical parameter matching within the Tiger Eye™ SFML series. The substitute part must maintain identical specifications across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (90)
• Pitch configuration (0.050" mating pitch, 0.050" row spacing)
• Number of rows (2)
• Mounting method (Through Hole)
• Contact finish at mating surface (Gold)
• Current and voltage ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (Liquid Crystal Polymer)
• Flammability rating (UL94 V-0)
• RoHS compliance status

The SFML-145-01-S-D meets all these criteria and is classified as a direct equivalent substitute within the same product series.

Parameter Comparison

Engineering Selection Recommendations

Both the SFML-145-L1-S-D and SFML-145-01-S-D are Active status products from Samtec Inc. with full RoHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all electrical and mechanical parameters. Selection between these two part numbers may be based on inventory availability, supply chain logistics, or specific procurement requirements, as both meet identical performance and compliance specifications for 90 position, 0.050" pitch receptacle connector applications.

Frequently Asked Questions (FAQ)

Q: Can SFML-145-01-S-D be used as a direct replacement for SFML-145-L1-S-D?

A: Yes. Both parts are 90 position receptacles with identical pitch (0.050"), row configuration (2 rows at 0.050" spacing), mounting method (through hole), contact ratings (3.2A per contact, 250VAC), and operating temperature range (-55°C ~ 125°C). All electrical and mechanical parameters match exactly.

Q: Are there any differences in compliance or certification between these parts?

A: Both parts carry identical certifications: RoHS3 compliance, UL94 V-0 flammability rating, and EAR99 export classification. No compliance differences exist between the two part numbers.

Q: What determines whether a part can substitute for the SFML-145-L1-S-D?

A: Substitution requires matching specifications across connector type (receptacle), position count (90), mating pitch (0.050"), row count and spacing (2 rows at 0.050"), mounting type (through hole), contact finish (gold at mating surface), current/voltage ratings (3.2A per contact, 250VAC), operating temperature (-55°C ~ 125°C), insulation material (LCP), and flammability rating (UL94 V-0).

Q: Are these parts interchangeable in PCB assembly?

A: Yes. Both parts feature identical through-hole termination, solder mounting, locking ramp fastening, and physical dimensions (0.180" insulation height, 0.120" contact post length). PCB footprints and assembly processes are identical.

Q: What is the difference between the L1 and 01 designations in the part numbers?

A: The parameter data provided does not specify the technical distinction between the L1 and 01 designations. Both parts are functionally equivalent across all documented electrical and mechanical specifications.
