AMC50MMSD Equivalent & Substitute Parts

Part Overview

The AMC50MMSD is a 100-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 -65°C to 200°C. The AMC50MMSD is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure procurement availability for new applications and legacy system support.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC50MMSD with the active RMC50MMSD is based on alignment of critical electrical and mechanical parameters that define functional compatibility in card edge connector applications. Both connectors maintain identical specifications for the following parameters: 100-position configuration, 0.100" (2.54mm) pitch, dual read-out, 2-row arrangement, gold contact finish at 30.0µin thickness, -65°C to 200°C operating temperature range, PPS insulation material, solder termination, ROHS3 compliance, and MSL 1 rating.

The RMC50MMSD qualifies as a direct substitute based on these matching parameters. Differences in contact material (phosphor bronze versus beryllium copper), card thickness specification (0.062" specified for RMC50MMSD versus unspecified for AMC50MMSD), flange opening orientation (top opening versus side opening), and color designation (black versus unspecified) do not preclude functional substitution when the primary electrical and mechanical interface requirements are met.

Engineering Selection Recommendations

The RMC50MMSD is the direct active substitute for the obsolete AMC50MMSD. Selection of the RMC50MMSD is supported by the following factors:

Product Status: The RMC50MMSD maintains active product status with confirmed inventory availability (1027 pieces), whereas the AMC50MMSD is obsolete with no ongoing manufacturing support.

Regulatory Compliance: Both connectors achieve ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements. The RMC50MMSD carries ECCN EAR99 classification with HTSUS code 8536.69.4040.

Electrical and Mechanical Compatibility: The RMC50MMSD maintains all critical interface parameters including 100-position configuration, 0.100" pitch, dual read-out, gold contact finish at specified thickness, and identical operating temperature range. These parameters ensure functional compatibility with existing female edgecard designs.

Certification and Quality: Both parts carry MSL 1 rating, indicating unlimited moisture sensitivity protection and suitability for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the RMC50MMSD directly replace the AMC50MMSD in existing designs?

A: Yes. The RMC50MMSD maintains identical electrical interface specifications including 100-position configuration, 0.100" (2.54mm) pitch, dual read-out, gold contact finish, and operating temperature range. These parameters define functional compatibility with female edgecard interfaces.

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

A: Both materials provide acceptable electrical conductivity and contact reliability for card edge connector applications. The contact finish (gold plating at 30.0µin) is identical on both parts, which is the primary determinant of contact performance and corrosion resistance.

Q: Does the card thickness specification of 0.062" (1.57mm) for the RMC50MMSD affect compatibility?

A: The card thickness specification indicates the RMC50MMSD is designed for 0.062" edgecards. Compatibility depends on the actual card thickness in the application. The unspecified card thickness for the AMC50MMSD does not indicate broader compatibility; application-specific card thickness must be verified.

Q: What is the difference between side opening and top opening flange features?

A: The flange opening orientation (side opening for AMC50MMSD versus top opening for RMC50MMSD) affects the physical insertion direction and mounting orientation of the connector on the printed circuit board. Selection depends on the specific board layout and mechanical constraints of the application.

Q: Are both connectors suitable for high-temperature applications?

A: Yes. Both the AMC50MMSD and RMC50MMSD operate across -65°C to 200°C, supporting high-temperature industrial and aerospace applications. The PPS insulation material and gold contact finish support this temperature range.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 rating indicates the connector has unlimited shelf life and does not require controlled moisture storage conditions. Standard storage and handling procedures are sufficient.

Q: Is the RMC50MMSD available for immediate procurement?

A: Yes. The RMC50MMSD is classified as active product status with 1027 pieces confirmed in stock, ensuring availability for new designs and legacy system support.
