Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 55510-110TRLF is a direct functional substitute for the Molex 0873811084. Both parts share identical mechanical and electrical specifications across all critical parameters. The Amphenol part offers extended operating temperature range (-55°C to 125°C versus -105°C) and higher voltage rating (200V versus 125V), providing additional design margin. Both parts are active in production and RoHS compliant. The primary difference is packaging format: Amphenol supplies in tape and reel format, while Molex uses tube packaging.

Samtec S2M-105-02-F-D meets all mechanical compatibility requirements and shares the same 2.00mm pitch, 10-position configuration, and surface mount solder termination. The Samtec part is active in production and ROHS3 compliant. Operating temperature range extends to 125°C, and current rating per contact (2.6A) exceeds the original specification. Contact finish thickness on mating surfaces is thinner (3.00µin) compared to the Molex original (15.0µin). Voltage rating is not specified for this part.

All three parts are active products with current availability and comply with applicable regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 55510-110TRLF directly replace the Molex 0873811084 in existing designs?

A: Yes. Both connectors share identical pitch (0.079"), position count (10), row configuration (2 rows), mounting type (surface mount), and fastening mechanism (push-pull). Mechanical and electrical parameters are equivalent. The primary consideration is packaging format: Amphenol supplies in tape and reel, while Molex uses tube.

Q: What are the key differences between the Samtec S2M-105-02-F-D and the Molex original?

A: The Samtec part meets all mechanical compatibility requirements. Differences include contact finish thickness on mating surfaces (3.00µin versus 15.0µin for Molex), extended operating temperature range (-55°C to 125°C versus -105°C), and higher current rating per contact (2.6A versus 1.9A). Voltage rating is not specified for the Samtec part.

Q: Are all three parts RoHS compliant?

A: Yes. The Molex 0873811084 and Samtec S2M-105-02-F-D are ROHS3 compliant. The Amphenol ICC 55510-110TRLF is RoHS compliant.

Q: What is the impact of different contact finish thicknesses?

A: Contact finish thickness affects durability and wear resistance. The Amphenol part (30.0µin) provides the thickest mating contact finish, followed by Molex (15.0µin), and Samtec (3.00µin). Thicker finishes generally offer extended contact life under repeated mating cycles.

Q: Does packaging format affect connector performance?

A: No. Tape and reel (TR) and tube packaging formats do not affect electrical or mechanical performance. The choice depends on assembly process requirements and volume handling procedures.

Q: Can the Samtec part be used if voltage rating is not specified?

A: The Samtec S2M-105-02-F-D meets all mechanical and thermal specifications. However, the unspecified voltage rating requires design review against application requirements. Contact Samtec directly for voltage rating confirmation if this parameter is critical to your application.
