AMC04MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC04MMSD is an 8-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 gold-plated beryllium copper contacts, dual read-out configuration, and operates across -65°C to 200°C. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives 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 AMC04MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Gender: Male
• Number of Positions: 8
• Number of Rows: 2
• Pitch: 0.100" (2.54mm)
• Termination: Solder
• Operating Temperature Range: -65°C ~ 200°C
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Material - Insulation: Polyphenylene Sulfide (PPS)
• Flange Feature: Flush Mount, Unthreaded, 0.125" (3.18mm) Dia
• Read Out: Dual
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The RMC04MMSD meets all mandatory matching parameters and is classified as an active product, providing direct functional equivalence for the obsolete AMC04MMSD.

Parameter Comparison

Engineering Selection Recommendations

The RMC04MMSD is the direct active equivalent for the obsolete AMC04MMSD. Both connectors maintain identical electrical and thermal specifications, including 8-position dual read-out configuration, 0.100" pitch, gold contact finish at 30.0µin thickness, and full operating range of -65°C to 200°C. Both parts are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

The RMC04MMSD is currently in active production with 650 units in stock, ensuring availability for immediate procurement. The substitute part differs from the main part in contact material composition (phosphor bronze versus beryllium copper) and flange opening orientation (top opening versus side opening), with the RMC04MMSD specifying a defined card thickness of 0.062" (1.57mm). These differences do not affect functional compatibility for applications designed around the 8-position, 0.100" pitch card edge connector interface.

Frequently Asked Questions (FAQ)

Q: Can the RMC04MMSD directly replace the AMC04MMSD in existing designs?

A: The RMC04MMSD provides functional equivalence across all critical electrical and thermal parameters. The connector maintains the same 8-position, dual read-out configuration, 0.100" pitch, gold contact finish, and operating temperature range. Physical differences in flange opening orientation and contact material do not affect interface compatibility with standard female edgecards.

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

A: Both materials are standard contact materials for card edge connectors and provide equivalent electrical performance and durability. The contact finish (gold plating at 30.0µin) is identical on both parts, which is the primary factor determining electrical characteristics and corrosion resistance.

Q: Does the RMC04MMSD flange opening orientation affect installation?

A: The RMC04MMSD features top opening versus the side opening of the AMC04MMSD. This difference affects the mechanical approach angle during card insertion but does not alter the electrical interface or contact engagement with female edgecards.

Q: Are both parts compliant with current regulatory standards?

A: Both the AMC04MMSD and RMC04MMSD are ROHS3 compliant and REACH unaffected. The RMC04MMSD, as an active product, maintains current compliance certifications.

Q: What is the card thickness specification for the RMC04MMSD?

A: The RMC04MMSD is specified for 0.062" (1.57mm) card thickness. This specification should be verified against the female edgecard thickness in the target application.

Q: Why is the AMC04MMSD classified as obsolete?

A: The AMC04MMSD has been discontinued by the manufacturer. The RMC04MMSD serves as the active production equivalent, ensuring continued availability and support for this connector interface.
