AMC48MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC48MMSD is a 96-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards using a 0.100" (2.54mm) pitch. This connector features dual read-out configuration, gold-plated beryllium copper contacts, and operates across a temperature range of -65°C to 200°C. The AMC48MMSD is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration requirements.

Key Parameters

Substitute Part Grouping Explanation

The RMC48MMSD qualifies as a direct substitute for the AMC48MMSD based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Number of Positions: 96
• Number of Rows: 2
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Card Type: Fits Female Edgecards
• Read Out: Dual
• Termination: Solder
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Operating Temperature Range: -65°C ~ 200°C
• Material - Insulation: Polyphenylene Sulfide (PPS)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameters:

• Contact Material: Phosphor Bronze (RMC48MMSD) vs. Beryllium Copper (AMC48MMSD)
• Flange Feature Opening: Top Opening (RMC48MMSD) vs. Side Opening (AMC48MMSD)
• Card Thickness: 0.062" (1.57mm) specified for RMC48MMSD
• Mounting Type: Through Hole (RMC48MMSD) vs. unspecified for AMC48MMSD
• Color: Black (RMC48MMSD)
• Product Status: Active (RMC48MMSD) vs. Obsolete (AMC48MMSD)

The RMC48MMSD maintains electrical and mechanical compatibility through identical position count, pitch, row configuration, contact finish specifications, and operating parameters. The substitute part is currently in active production status with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RMC48MMSD is the appropriate substitute for the obsolete AMC48MMSD. Both connectors maintain identical electrical specifications including position count, pitch, contact finish thickness, and operating temperature range. Both parts satisfy ROHS3 compliance and carry unlimited moisture sensitivity classification.

The RMC48MMSD is currently in active production status, ensuring long-term availability and supply chain continuity. The substitute part is manufactured by the same original equipment manufacturer, Sullins Connector Solutions, providing design consistency and quality assurance equivalent to the original specification.

The primary differences between the parts—contact material composition (phosphor bronze versus beryllium copper) and flange opening orientation (top opening versus side opening)—do not affect the core electrical or mechanical interface requirements for standard card edge connector applications. Both materials provide appropriate contact resistance and durability characteristics for the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the RMC48MMSD directly replace the AMC48MMSD in existing designs?

A: The RMC48MMSD maintains identical electrical and mechanical interface specifications with the AMC48MMSD. Both connectors feature 96 positions arranged in 2 rows at 0.100" pitch, dual read-out configuration, and gold-plated contacts with identical finish thickness. Physical board layout compatibility depends on the specific flange opening orientation and mounting configuration of the original design.

Q: What is the difference between the contact materials used in these connectors?

A: The AMC48MMSD uses beryllium copper contacts, while the RMC48MMSD uses phosphor bronze contacts. Both materials provide appropriate electrical conductivity and mechanical durability for card edge connector applications within the specified operating temperature range of -65°C to 200°C.

Q: Are both connectors RoHS compliant?

A: Both the AMC48MMSD and RMC48MMSD are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What is the significance of the flange feature differences?

A: The AMC48MMSD features a side opening flange, while the RMC48MMSD features a top opening flange. This difference affects the physical orientation and mounting approach but does not alter the electrical interface or contact specifications.

Q: Is the RMC48MMSD currently available for procurement?

A: The RMC48MMSD is classified as an active product with confirmed inventory of 869 pieces in stock, providing immediate availability for component procurement and system integration.

Q: Do both connectors support solder termination?

A: Both the AMC48MMSD and RMC48MMSD utilize solder termination, maintaining identical assembly and integration requirements for printed circuit board applications.
