SFM-110-L2-S-D-P-TR Equivalent & Substitute Parts

Part Overview

The SFM-110-L2-S-D-P-TR is a 20-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for surface mount applications with 0.050" (1.27mm) pitch. This connector features gold-plated mating contacts, push-pull fastening, and is rated for 3.2A per contact at 250VAC. The part is active in production and ROHS3 compliant with MSL 1 rating.

Equivalent and substitute parts are identified when design requirements allow flexibility in fastening mechanisms, contact materials, or manufacturer sourcing while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-110-L2-S-D-P-TR is determined by the following critical parameters:

Primary Compatibility Criteria:

• 20-position receptacle configuration
• 0.050" (1.27mm) mating pitch
• 2-row layout with 0.050" row spacing
• Surface mount solder termination
• Gold-plated mating contacts
• Square contact geometry
• Liquid Crystal Polymer insulation
• ROHS3 compliance

Secondary Variation Parameters (Allow Substitution):

• Fastening mechanism (Push-Pull vs. Board Lock)
• Contact material composition (Beryllium Copper, Copper Alloy, Phosphor Bronze)
• Contact finish on post (Tin vs. Gold)
• Insulation height tolerance (0.181" to 0.187")
• Operating temperature range (within application limits)
• Current rating (when application requirements are met)
• Manufacturer source (Samtec, TE Connectivity, Harwin)

Parameter Comparison

Engineering Selection Recommendations

Samtec SFM Series (SFM-110-02-S-D-K-TR and SFM-110-02-S-D-P-TR): These parts are direct equivalents within the same product family. Both maintain identical electrical specifications, operating temperature range (-55°C ~ 125°C), current rating (3.2A per contact), and voltage rating (250VAC). All three Samtec variants are ROHS3 compliant with MSL 1 rating. Selection between these parts depends on fastening mechanism preference (Push-Pull vs. Board Lock) and packaging format (Tape & Reel availability).

TE Connectivity 5-104652-2: This part shares core mechanical and electrical compatibility with identical pitch, row configuration, and contact geometry. Operating temperature range is -65°C ~ 105°C, which is narrower at the high end. Current and voltage ratings are not specified. Packaging is Tube format. This part is suitable for applications where the lower operating temperature maximum is acceptable and fastening mechanism is Board Lock.

Harwin M50-4301045: This part maintains pitch, row spacing, and contact geometry compatibility. Operating temperature range is -40°C ~ 105°C. Current rating is specified as 1A per contact, which is lower than the SFM-110-L2-S-D-P-TR (3.2A). Voltage rating is not specified. This part is suitable only for applications with current requirements not exceeding 1A per contact. Packaging is Tube format.

All substitute parts are ROHS3 compliant with MSL 1 rating, meeting standard compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can SFM-110-02-S-D-K-TR replace SFM-110-L2-S-D-P-TR directly? A: Yes, within the same Samtec Tiger Eye™ SFM series. Both parts share identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), and mechanical pitch specifications. The difference is the fastening mechanism: Board Lock (K) versus Push-Pull (P). Verify your application's fastening requirement before substitution.

Q: What is the difference between the Samtec and TE Connectivity versions? A: Both maintain 20-position, 0.050" pitch configuration with gold-plated mating contacts. Samtec parts specify 3.2A per contact and 250VAC rating. TE Connectivity 5-104652-2 does not specify current or voltage ratings. Operating temperature range differs: Samtec is -55°C ~ 125°C; TE Connectivity is -65°C ~ 105°C. Packaging differs: Samtec uses Tape & Reel; TE Connectivity uses Tube.

Q: Is the Harwin M50-4301045 suitable as a substitute? A: The Harwin M50-4301045 is mechanically compatible but has a reduced current rating of 1A per contact compared to the SFM-110-L2-S-D-P-TR (3.2A per contact). Use this part only if your application current requirements do not exceed 1A per contact. Operating temperature range is -40°C ~ 105°C, which is narrower than the Samtec part.

Q: What packaging formats are available? A: Samtec SFM series parts are supplied in Tape & Reel (TR) format. TE Connectivity 5-104652-2 and Harwin M50-4301045 are supplied in Tube format. Select based on your assembly process requirements and volume needs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts—SFM-110-L2-S-D-P-TR, SFM-110-02-S-D-K-TR, SFM-110-02-S-D-P-TR, 5-104652-2, and M50-4301045—are ROHS3 compliant with MSL 1 (Unlimited) rating.

Q: What determines substitution eligibility? A: Core substitution criteria are 20-position receptacle configuration, 0.050" (1.27mm) mating pitch, 2-row layout with 0.050" row spacing, surface mount solder termination, gold-plated mating contacts, square contact geometry, and LCP insulation. Variations in fastening mechanism, contact material, and post finish are allowable if application requirements are met. Current and voltage ratings must be verified against application specifications.
