Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 63453-028LF are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• 28-position receptacle configuration with female socket contacts
• 0.079" (2.00mm) mating pitch and row spacing
• Through-hole solder termination
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Operating temperature range of -55°C to 125°C
• Board-to-board or board-to-cable connectivity

The Samtec MMS-114-01-F-DV and MMS-114-01-H-DV meet these core electrical and mechanical requirements. Both parts maintain the same connector topology, pitch geometry, and termination method. Differences in contact finish thickness, insulation material composition, and packaging format do not affect substitution eligibility within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS requirements, ensuring long-term availability and regulatory compliance for industrial and medical applications.

The Amphenol ICC 63453-028LF serves as the primary reference part with established performance characteristics across the specified operating range.

The Samtec MMS-114-01-F-DV provides equivalent functionality with tube packaging, matching the original packaging format. This part is suitable for applications where packaging consistency with existing supply chains is required.

The Samtec MMS-114-01-H-DV offers the same electrical and mechanical compatibility with bulk packaging. This configuration is appropriate for high-volume production environments where bulk packaging reduces material handling and cost per unit.

Selection between substitute parts should be based on packaging requirements and inventory management practices rather than electrical performance, as all parts meet the core substitution criteria.

Frequently Asked Questions (FAQ)

Q: Are the Samtec MMS-114 series connectors mechanically compatible with the Amphenol ICC 63453-028LF?

A: Yes. Both the MMS-114-01-F-DV and MMS-114-01-H-DV maintain identical mating pitch (0.079"), row spacing (0.079"), number of positions (28), and push-pull fastening mechanism. Through-hole solder termination and board-to-board connectivity are preserved across all three parts.

Q: What is the difference between MMS-114-01-F-DV and MMS-114-01-H-DV?

A: The primary differences are packaging format and contact finish specifications. The MMS-114-01-F-DV is supplied in tube packaging with 3.00µin mating contact finish thickness. The MMS-114-01-H-DV is supplied in bulk packaging with 30.0µin mating contact finish thickness and gold post finish. Both maintain identical electrical and mechanical performance.

Q: Can I use these substitute parts in medical applications?

A: The 63453-028LF is specified for medical applications. The Samtec MMS-114 series parts are active products with ROHS3 compliance and appropriate moisture sensitivity ratings. Application suitability should be confirmed against specific medical device requirements and regulatory standards applicable to your design.

Q: How do the current ratings compare?

A: The 63453-028LF is rated at 2A, while both Samtec MMS-114 variants are rated at 3.9A per contact. The higher current rating of the substitute parts does not affect substitution eligibility and provides additional design margin for power distribution applications.

Q: What is the impact of different insulation materials?

A: The 63453-028LF uses glass-filled Polycyclohexylenedimethylene Terephthalate (PCT), while the Samtec MMS-114 series uses Liquid Crystal Polymer (LCP). Both materials meet the specified operating temperature range (-55°C to 125°C) and UL94 V-0 flammability requirements. Material selection does not affect connector substitution within the specified parameter constraints.

Q: Are there any PCB layout considerations when switching between these parts?

A: The insulation height differs slightly: 63453-028LF at 0.177" (4.50mm) versus MMS-114 at 0.175" (4.45mm). Contact post length also varies: 63453-028LF at 0.098" (2.50mm) versus MMS-114 at 0.115" (2.92mm). These dimensional differences may require PCB footprint verification to ensure proper solder joint formation and mechanical clearance.
