AMC46MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC46MMSD is a 92-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards at 0.100" (2.54mm) pitch. This connector features dual read-out configuration with gold-plated beryllium copper contacts and operates across -65°C to 200°C. The AMC46MMSD is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC46MMSD with the RMC46MMSD is based on alignment of the following critical parameters:

Matching Parameters:

• Number of Positions: 92
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Number of Rows: 2
• Card Type: Fits Female Edgecards
• Termination: Solder
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Operating Temperature Range: -65°C ~ 200°C
• Insulation Material: Polyphenylene Sulfide (PPS)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameters:

• Product Status: Obsolete (AMC46MMSD) vs. Active (RMC46MMSD)
• Contact Material: Beryllium Copper vs. Phosphor Bronze
• Card Thickness: Not specified vs. 0.062" (1.57mm)
• Mounting Type: Not specified vs. Through Hole
• Flange Feature: Side Opening vs. Top Opening
• Color: Not specified vs. Black
• ECCN: OBSOLETE vs. EAR99

The RMC46MMSD maintains functional equivalence through identical electrical and mechanical interface specifications while providing active product status and regulatory compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The RMC46MMSD serves as the direct active equivalent to the obsolete AMC46MMSD. Selection of the RMC46MMSD is appropriate for applications requiring:

• Continued supply of 92-position male card edge connectors at 0.100" pitch
• ROHS3 compliance and regulatory documentation
• Active product status with manufacturer support
• Identical electrical interface specifications and operating temperature range
• Solder termination with gold-plated contacts

The RMC46MMSD maintains the same connector footprint and electrical performance as the AMC46MMSD while providing documented compliance certifications and active manufacturing status. The contact material difference (phosphor bronze versus beryllium copper) and specified card thickness of 0.062" (1.57mm) represent design refinements in the active product line.

Frequently Asked Questions (FAQ)

Q: Can the RMC46MMSD directly replace the AMC46MMSD in existing designs?

A: The RMC46MMSD maintains identical electrical and mechanical interface specifications including 92 positions, 0.100" pitch, dual read-out configuration, and solder termination. The connector is designed to interface with the same female edgecard specifications. Physical mounting differences (top opening versus side opening flange) and the specified card thickness of 0.062" (1.57mm) require verification against specific board layout requirements.

Q: What is the significance of the contact material difference between beryllium copper and phosphor bronze?

A: Both materials provide gold-plated contact surfaces with identical finish thickness of 30.0µin (0.76µm). The contact material difference reflects design evolution in the active product line. Both materials maintain the same operating temperature range of -65°C to 200°C and are suitable for solder termination applications.

Q: Are there compliance differences between the two parts?

A: Both the AMC46MMSD and RMC46MMSD are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). The RMC46MMSD includes ECCN classification (EAR99) and HTSUS code (8536.69.4040) documentation, reflecting its active product status.

Q: What does the specified card thickness of 0.062" (1.57mm) for the RMC46MMSD indicate?

A: The card thickness specification indicates the nominal thickness of the female edgecard with which the RMC46MMSD is designed to interface. This parameter was not specified for the obsolete AMC46MMSD. Verification of existing edgecard thickness is required to ensure proper connector engagement.

Q: How do the flange features differ between these connectors?

A: The AMC46MMSD features a side opening flange configuration, while the RMC46MMSD features a top opening flange. Both are flush mount with unthreaded 0.125" (3.18mm) diameter flanges. The opening orientation difference may affect board layout and component placement considerations.
