AMC52MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC52MMSD is a 104-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 AMC52MMSD is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while offering current product availability and support.

Substitute Part Grouping Explanation

Substitute parts for the AMC52MMSD are identified based on strict electrical and mechanical parameter alignment. The following parameters determine substitution eligibility:

Critical Parameters (Must Match Exactly):

Number of Positions: 104
Pitch: 0.100" (2.54mm)
Gender: Male
Number of Rows: 2
Card Type: Fits Female Edgecards
Termination: Solder
Contact Finish: Gold
Operating Temperature Range: -65°C ~ 200°C

Important Parameters (Must Match or Exceed):

Material - Insulation: Polyphenylene Sulfide (PPS)
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

The RMC52MMSD meets all critical and important parameters, establishing it as a direct functional equivalent. Differences in contact material (phosphor bronze versus beryllium copper), flange opening configuration, and color do not affect electrical or mechanical compatibility within the specified parameter constraints.

Engineering Selection Recommendations

The RMC52MMSD is the direct active equivalent for the obsolete AMC52MMSD. Selection of the RMC52MMSD is supported by the following engineering criteria:

Product Status: The RMC52MMSD carries active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The AMC52MMSD is classified as obsolete and should not be selected for new designs or production applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

Electrical and Mechanical Compatibility: The RMC52MMSD maintains all critical electrical and mechanical parameters specified for the AMC52MMSD, including 104-position configuration, 0.100" pitch, dual read-out, gold contact finish, and -65°C to 200°C operating temperature range.

Functional Equivalence: Differences in contact material (phosphor bronze versus beryllium copper), flange opening orientation (top versus side), and specified card thickness do not compromise functional compatibility within the defined parameter set. These variations represent design refinements in the active product line.

Frequently Asked Questions (FAQ)

Q: Can the RMC52MMSD directly replace the AMC52MMSD in existing designs?

A: Yes. The RMC52MMSD maintains all critical electrical and mechanical parameters required for functional equivalence, including 104-position configuration, 0.100" pitch, male gender, dual read-out, solder termination, gold contact finish, and -65°C to 200°C operating temperature range.

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 within the specified operating parameters. The phosphor bronze contact material in the RMC52MMSD represents a design refinement in the active product line and does not affect functional compatibility.

Q: Does the flange opening orientation difference (side opening versus top opening) affect compatibility?

A: The flange opening orientation difference reflects design variations between the obsolete and active product lines. Both configurations maintain the same flush mount, unthreaded 0.125" diameter flange specification and do not affect electrical or mechanical compatibility with female edgecards.

Q: Is the specified card thickness of 0.062" (1.57mm) for the RMC52MMSD a limiting factor?

A: The card thickness specification for the RMC52MMSD indicates the connector is designed for standard 0.062" edgecards. This specification does not restrict compatibility; it defines the intended application. Verify that your edgecard thickness matches this specification.

Q: Are there any moisture sensitivity or storage considerations?

A: Both the AMC52MMSD and RMC52MMSD carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.

Q: What is the inventory status for the RMC52MMSD?

A: The RMC52MMSD is available with 765 pieces in stock as new original inventory, supporting immediate procurement for production requirements.
