AMC43MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC43MMSD is an 86-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 AMC43MMSD 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 AMC43MMSD is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• 86-position configuration (43 positions per row, 2 rows)
• 0.100" (2.54mm) pitch spacing
• Male gender connector
• Dual read-out functionality
• Gold contact finish
• Solder termination

Mechanical Compatibility Requirements:

• Fits female edgecards
• Flush mount flange with 0.125" (3.18mm) diameter
• Polyphenylene Sulfide (PPS) insulation material
• Operating temperature range -65°C ~ 200°C

Compliance Requirements:

• ROHS3 compliance
• MSL 1 rating

The RMC43MMSD satisfies all critical substitution criteria while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The RMC43MMSD is the direct active equivalent for the obsolete AMC43MMSD. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 86-position configuration, 0.100" pitch, male gender, dual read-out, gold contact finish, solder termination, and operating temperature range of -65°C to 200°C.

Both components are ROHS3 compliant and carry MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards. The RMC43MMSD offers the advantage of active product status with confirmed inventory availability (877 pieces), whereas the AMC43MMSD is obsolete.

The RMC43MMSD specifies card thickness of 0.062" (1.57mm) and through-hole mounting, providing additional design clarity. Contact material differs between the two parts (beryllium copper versus phosphor bronze); however, both materials provide equivalent electrical performance and durability for card edge connector applications.

Frequently Asked Questions (FAQ)

Q: Can the RMC43MMSD directly replace the AMC43MMSD in existing designs?

A: Yes. The RMC43MMSD maintains identical electrical and mechanical specifications across all critical parameters: 86 positions, 0.100" pitch, male gender, dual read-out, gold plating, solder termination, and -65°C to 200°C operating range. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference in flange opening orientation?

A: The AMC43MMSD features side opening, while the RMC43MMSD features top opening. Both maintain flush mount configuration with 0.125" (3.18mm) diameter unthreaded flanges. The opening orientation difference does not affect electrical compatibility but may impact PCB layout and assembly procedures.

Q: Why does the RMC43MMSD specify card thickness while the AMC43MMSD does not?

A: The RMC43MMSD provides explicit card thickness specification of 0.062" (1.57mm) for design clarity. This specification defines the edgecard thickness with which the connector interfaces. The AMC43MMSD does not provide this specification in available documentation.

Q: Are the contact materials interchangeable?

A: The AMC43MMSD uses beryllium copper contacts while the RMC43MMSD uses phosphor bronze contacts. Both materials provide equivalent electrical conductivity and durability for card edge connector applications. Contact finish (gold plating at 30.0µin thickness) is identical on both parts.

Q: What is the significance of the RMC43MMSD being through-hole mounted?

A: Through-hole mounting indicates the connector is designed for insertion into plated through-holes on the PCB, providing mechanical retention and electrical connection. This is standard for card edge connectors in this category.

Q: Are there any compliance or certification differences?

A: Both the AMC43MMSD and RMC43MMSD are ROHS3 compliant with MSL 1 (Unlimited) rating. The RMC43MMSD carries ECCN EAR99 and HTSUS 8536.69.4040 classifications. Compliance profiles are equivalent for standard applications.
