AMC23MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC23MMSD is a 46-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 AMC23MMSD 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 AMC23MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 46
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Number of Rows: 2
• Termination: Solder
• Contact Finish: Gold
• Operating Temperature Range: -65°C ~ 200°C
• Insulation Material: Polyphenylene Sulfide (PPS)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RMC23MMSD meets all mandatory matching parameters and qualifies as a direct substitute. The substitute part maintains functional and electrical equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The RMC23MMSD is the direct substitute for the obsolete AMC23MMSD. Both connectors are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical specifications across all critical parameters: 46-position configuration, 0.100" pitch, dual read-out, solder termination, gold contact finish, and operating temperature range of -65°C to 200°C.

The RMC23MMSD offers the following advantages:

Product Status: The RMC23MMSD maintains active product status with confirmed inventory availability (913 pieces), whereas the AMC23MMSD is obsolete with limited remaining stock (1112 pieces). Active status ensures long-term availability and continued manufacturer support.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Contact Material Difference: The RMC23MMSD uses phosphor bronze contacts compared to beryllium copper in the AMC23MMSD. Both materials provide equivalent electrical performance and durability within the specified operating parameters.

Mechanical Configuration: The RMC23MMSD specifies a card thickness of 0.062" (1.57mm) and includes through-hole mounting designation with top opening flange configuration, compared to the side opening configuration of the AMC23MMSD. These mechanical differences do not affect electrical substitution compatibility.

Frequently Asked Questions (FAQ)

Q: Can the RMC23MMSD directly replace the AMC23MMSD in existing designs?

A: Yes. The RMC23MMSD meets all critical electrical and mechanical parameters required for direct substitution. Both connectors feature 46 positions, 0.100" pitch, dual read-out configuration, solder termination, gold plating, and identical operating temperature range.

Q: What is the difference between the contact materials?

A: The AMC23MMSD uses beryllium copper contacts, while the RMC23MMSD uses phosphor bronze contacts. Both materials provide equivalent electrical conductivity and contact reliability within the specified operating parameters and temperature range.

Q: Does the flange opening direction affect compatibility?

A: The flange opening direction (side opening versus top opening) is a mechanical design feature that does not affect electrical compatibility. Selection between these configurations depends on the specific PCB layout and assembly requirements of the application.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the AMC23MMSD and RMC23MMSD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement and use.

Q: What is the significance of the card thickness specification?

A: The RMC23MMSD specifies a card thickness of 0.062" (1.57mm). This parameter indicates the thickness of the female edgecard that the connector accommodates. The AMC23MMSD does not specify this parameter but is designed to interface with female edgecards of compatible thickness.

Q: Why is the AMC23MMSD classified as obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued active production and support for this part number. The RMC23MMSD represents the active equivalent offering continued availability and manufacturer support.
