AMC09MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC09MMSD is an 18-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 with gold-plated beryllium copper contacts and operates across -65°C to 200°C. The AMC09MMSD is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC09MMSD with the active RMC09MMSD is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Identical 18-position configuration with 0.100" (2.54mm) pitch
• Dual read-out functionality maintained
• Gold contact finish with equivalent 30.0µin (0.76µm) thickness
• Matching operating temperature range of -65°C to 200°C
• Polyphenylene Sulfide (PPS) insulation material

Mechanical Compatibility:

• Male gender connector for female edgecard interface
• Solder termination method
• Flush mount flange with 0.125" (3.18mm) diameter
• Two-row configuration with 9 positions per row

Compliance Equivalence:

• Both parts maintain ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited) for both
• REACH Unaffected status maintained

The primary differences between these connectors are contact material composition (beryllium copper versus phosphor bronze), flange opening orientation (side opening versus top opening), and mounting type specification, which do not affect functional interchangeability in standard card edge applications.

Parameter Comparison

Engineering Selection Recommendations

The RMC09MMSD serves as the direct active equivalent for the obsolete AMC09MMSD. Selection of the RMC09MMSD is supported by the following engineering criteria:

Product Status Alignment: The RMC09MMSD maintains active product status with current manufacturing and distribution support, eliminating supply chain risk associated with the obsolete AMC09MMSD classification.

Compliance Certification: Both connectors maintain identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory requirements are met without modification to existing design documentation or procurement specifications.

Electrical and Mechanical Equivalence: The RMC09MMSD preserves all critical functional parameters including 18-position configuration, 0.100" pitch, dual read-out, gold contact finish, and -65°C to 200°C operating temperature range. These parameters ensure direct functional replacement in existing female edgecard interfaces.

Contact Material Consideration: The phosphor bronze contact material in the RMC09MMSD provides equivalent electrical performance and durability compared to the beryllium copper contacts in the AMC09MMSD for standard card edge connector applications.

Flange Opening Orientation: The RMC09MMSD features top opening orientation compared to the side opening of the AMC09MMSD. This difference does not affect electrical function and accommodates standard through-hole mounting practices.

Frequently Asked Questions (FAQ)

Q: Can the RMC09MMSD directly replace the AMC09MMSD in existing designs?

A: Yes. The RMC09MMSD maintains electrical and mechanical compatibility across all critical parameters including position count, pitch, gender, read-out configuration, termination method, contact finish, and operating temperature range. The connector interfaces identically with female edgecards designed for the AMC09MMSD.

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

A: Both materials provide suitable electrical conductivity and durability for card edge connector applications. Phosphor bronze in the RMC09MMSD delivers equivalent performance in standard operating conditions within the specified -65°C to 200°C temperature range.

Q: Does the flange opening orientation change affect installation?

A: The RMC09MMSD features top opening orientation compared to the side opening of the AMC09MMSD. This difference accommodates through-hole mounting configuration and does not affect electrical interface or female edgecard compatibility.

Q: Are there compliance differences between these connectors?

A: No. Both the AMC09MMSD and RMC09MMSD maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). Regulatory requirements are identical between the two parts.

Q: What is the card thickness specification for the RMC09MMSD?

A: The RMC09MMSD is specified for 0.062" (1.57mm) card thickness. This specification should be verified against the female edgecard thickness in the target application to ensure proper mechanical fit and electrical contact.

Q: Is the black color of the RMC09MMSD a functional difference?

A: No. The black color is a cosmetic feature and does not affect electrical performance or mechanical compatibility. The color difference does not impact functional interchangeability.

Q: What inventory status should be considered for procurement?

A: The RMC09MMSD is available with 992 pieces in current stock as an active product. The AMC09MMSD is obsolete with limited remaining inventory of 691 pieces. Procurement should prioritize the RMC09MMSD for new designs and ongoing production requirements.
