Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-105-L2-S-D-A-P is determined by the following critical parameters:

Primary Substitution Criteria:

• Connector type: Receptacle
• Number of positions: 10
• Pitch - mating: 0.050" (1.27mm)
• Number of rows: 2
• Row spacing - mating: 0.050" (1.27mm)
• Mounting type: Surface Mount
• Termination: Solder
• Contact finish - mating: Gold
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact shape: Square

Identified Substitutes:

SFM-105-02-S-D-A-K and SFM-105-02-S-D-A-P are direct Samtec equivalents within the Tiger Eye™ SFM series. Both parts share identical electrical and mechanical specifications with the main part, with differences limited to fastening mechanism designation codes.

5-104652-1 (TE Connectivity AMPMODU 50/50 Grid) is a cross-manufacturer substitute that matches the core electrical and mechanical parameters. This part maintains the same pitch, position count, row configuration, and surface mount termination. Differences exist in operating temperature range, mated stacking heights, and material flammability rating documentation.

Parameter Comparison

Engineering Selection Recommendations

Samtec Tiger Eye™ SFM Series (SFM-105-02-S-D-A-K and SFM-105-02-S-D-A-P): These parts maintain full compatibility with the SFM-105-L2-S-D-A-P across all electrical and mechanical parameters. Both are active production parts with ROHS3 compliance and identical operating temperature ranges. Selection between these variants and the main part is based on fastening mechanism requirements as indicated by the part number suffix codes.

TE Connectivity 5-104652-1: This cross-manufacturer substitute provides equivalent electrical and mechanical function with the following considerations: operating temperature range is -65°C to 105°C (lower maximum temperature than Samtec parts), insulation height is 0.187" versus 0.185", and mated stacking heights differ (6.35mm, 8.13mm, 9.91mm versus 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, 11.76mm). The part is RoHS compliant and carries MSL 1 rating. Contact material is specified as Copper Alloy rather than Beryllium Copper.

Frequently Asked Questions (FAQ)

Q: Can SFM-105-02-S-D-A-K and SFM-105-02-S-D-A-P be used interchangeably with SFM-105-L2-S-D-A-P?

A: Yes. These Samtec parts share identical electrical specifications (10 positions, 0.050" pitch, 3.2A per contact, 250VAC rating), mechanical dimensions (0.185" insulation height, 0.050" row spacing), and operating temperature range (-55°C to 125°C). Differences are limited to fastening mechanism designation codes embedded in the part number suffix.

Q: What are the key differences between the Samtec and TE Connectivity options?

A: The primary differences are: (1) operating temperature maximum is 105°C for the TE part versus 125°C for Samtec parts, (2) insulation height is 0.187" versus 0.185", (3) mated stacking height options differ, and (4) contact material is Copper Alloy versus Beryllium Copper. All other electrical and mechanical parameters are equivalent.

Q: Are there any compliance or certification differences?

A: Samtec parts carry ROHS3 compliance certification. The TE Connectivity part is RoHS compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification. All parts are classified under HTSUS 8536.69.4040.

Q: What determines substitution eligibility for this connector family?

A: Substitution is valid when the following parameters match: 10-position receptacle configuration, 0.050" (1.27mm) mating pitch, 2-row layout with 0.050" row spacing, surface mount termination, gold-plated mating contacts, and LCP insulation material. Operating temperature, contact material composition, and stacking height options may vary within acceptable design parameters.

Q: Can the 5-104652-1 be used in applications requiring the full -55°C to 125°C temperature range?

A: No. The TE Connectivity 5-104652-1 is rated for -65°C to 105°C operation. Applications requiring temperatures above 105°C must use the Samtec Tiger Eye™ SFM series parts (SFM-105-L2-S-D-A-P, SFM-105-02-S-D-A-K, or SFM-105-02-S-D-A-P).
