AMC23MMST Equivalent & Substitute Parts

Part Overview

The AMC23MMST is a 46-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, gold-plated beryllium copper contacts, and operates across the temperature range of -65°C to 200°C. The AMC23MMST is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC23MMST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 46 (23 per row, 2 rows)
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Termination: Solder
• Contact finish: Gold at 30.0µin (0.76µm)
• Operating temperature range: -65°C to 200°C
• Insulation material: Polyphenylene Sulfide (PPS)
• Flange feature: Flush Mount, Top Opening, Threaded Insert, 4-40
• Compliance: ROHS3 Compliant, REACH Unaffected

The RMC23MMST qualifies as a direct substitute based on full alignment with these parameters. Variations in contact material (phosphor bronze versus beryllium copper), card thickness specification, color designation, and product status (active versus obsolete) do not preclude functional equivalence when all electrical and mechanical interface parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The RMC23MMST is the direct substitute for the obsolete AMC23MMST. Both connectors maintain identical electrical and mechanical interface specifications, including 46-position configuration, 0.100" pitch, dual read-out, solder termination, and gold contact finish at 30.0µin thickness. Both components operate across -65°C to 200°C and utilize PPS insulation material.

The RMC23MMST holds active product status, ensuring ongoing availability and manufacturing support. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The RMC23MMST is the appropriate selection for applications requiring the AMC23MMST, with no functional or compliance limitations introduced by the substitution.

Frequently Asked Questions (FAQ)

Q: Can the RMC23MMST directly replace the AMC23MMST in existing designs?

A: Yes. The RMC23MMST maintains identical electrical and mechanical interface parameters, including position count, pitch, termination type, contact finish specification, and operating temperature range. No design modifications are required.

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

A: Both materials provide suitable electrical conductivity and mechanical properties for card edge connector applications. The contact finish (gold plating at 30.0µin) is identical on both components, establishing the primary electrical interface. The base material difference does not affect connector performance within the specified operating parameters.

Q: Are there any compliance or regulatory differences between these connectors?

A: No. Both the AMC23MMST and RMC23MMST are ROHS3 compliant and REACH unaffected. Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Q: Does the card thickness specification of 0.062" (1.57mm) on the RMC23MMST impose any constraints?

A: The card thickness specification on the RMC23MMST indicates the connector is designed for edgecards of this thickness. This parameter does not restrict substitution; it specifies the intended application environment. Verify that your edgecard thickness matches this specification.

Q: What is the difference between the mounting type designation on the RMC23MMST?

A: The RMC23MMST specifies Through Hole mounting, indicating the solder termination points are designed for through-hole PCB assembly. This is consistent with the solder termination type and does not affect functional equivalence with the AMC23MMST.
