Engineering Selection Recommendations

Both the Amphenol ICC 63453-050LF and Samtec Inc. MMS-125-01-H-DV are active products with current manufacturing status and full regulatory compliance. The 63453-050LF carries UL94 V-0 flammability certification and RoHS compliance. The MMS-125-01-H-DV is ROHS3 compliant and REACH unaffected, providing equivalent environmental and safety standards.

Selection between these parts should be based on supply availability, lead time requirements, and inventory positioning. Both connectors satisfy identical mechanical and electrical interface requirements for board-to-board applications requiring 50-position, 2.00mm pitch receptacle connectivity with push-pull fastening and solder termination.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-125-01-H-DV directly replace the Amphenol ICC 63453-050LF?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (50), row configuration (2 rows), mounting type (through-hole), termination method (solder), fastening mechanism (push-pull), and mating contact finish (gold). They are mechanically and electrically interchangeable for board-to-board applications.

Q: Are there differences in contact performance between these two parts?

A: The Amphenol ICC 63453-050LF is rated at 2A per contact with 200V voltage rating. The Samtec MMS-125-01-H-DV is rated at 3.9A per contact. Both operate across -55°C to 125°C. Selection should align with application current and voltage requirements.

Q: What are the insulation material differences?

A: The Amphenol ICC 63453-050LF uses polycyclohexylenedimethylene terephthalate (PCT) glass-filled insulation. The Samtec MMS-125-01-H-DV uses liquid crystal polymer (LCP) insulation. Both materials provide equivalent mechanical and thermal performance within the specified operating range.

Q: Do both parts have the same contact post finish?

A: No. The Amphenol ICC 63453-050LF has tin-plated posts (60.0µin / 1.52µm). The Samtec MMS-125-01-H-DV has gold-plated posts (3.00µin / 0.076µm). Both finishes are suitable for solder termination.

Q: Are there physical dimension differences?

A: Insulation height differs slightly: Amphenol ICC 63453-050LF is 0.177" (4.50mm), while Samtec MMS-125-01-H-DV is 0.175" (4.45mm). Contact post length also differs: Amphenol ICC 63453-050LF is 0.098" (2.50mm), while Samtec MMS-125-01-H-DV is 0.115" (2.92mm). Verify PCB design accommodates these dimensional variations.

Q: What is the moisture sensitivity level for each part?

A: The Amphenol ICC 63453-050LF has MSL 1 (unlimited). The Samtec MMS-125-01-H-DV is not applicable for MSL classification. Both parts are suitable for standard handling and storage conditions.
