AMC47MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC47MMSD is a 94-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 AMC47MMSD 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 AMC47MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 94
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Number of Rows: 2
• Read Out: Dual
• Termination: Solder
• Contact Finish: Gold
• Operating Temperature Range: -65°C ~ 200°C
• Insulation Material: Polyphenylene Sulfide (PPS)
• RoHS Compliance: ROHS3 Compliant

The RMC47MMSD meets all mandatory matching parameters and is classified as an active product, making it a direct functional equivalent for the obsolete AMC47MMSD.

Parameter Comparison

Engineering Selection Recommendations

The RMC47MMSD is the direct substitute for the obsolete AMC47MMSD. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including position count, pitch, contact configuration, termination method, and operating temperature range. Both components satisfy ROHS3 compliance and REACH requirements.

The RMC47MMSD is currently in active production status with 885 units in stock, whereas the AMC47MMSD is obsolete with limited remaining inventory. For new designs and production continuity, the RMC47MMSD is the appropriate selection.

Differences between the two parts are limited to non-functional attributes: the RMC47MMSD features a black color insulation body, specifies card thickness compatibility of 0.062" (1.57mm), includes through-hole mounting designation, uses phosphor bronze contact material instead of beryllium copper, and has a top opening flange configuration compared to the side opening of the AMC47MMSD. These differences do not affect functional compatibility with female edgecard interfaces.

Frequently Asked Questions (FAQ)

Q: Can the RMC47MMSD directly replace the AMC47MMSD in existing designs?

A: Yes. The RMC47MMSD maintains identical electrical and mechanical specifications across all critical parameters: 94 positions, 0.100" pitch, dual read-out, solder termination, gold contact finish, and -65°C to 200°C operating range. Both use PPS insulation and comply with ROHS3 and REACH requirements.

Q: What are the differences between AMC47MMSD and RMC47MMSD?

A: The primary differences are product status (obsolete versus active), insulation color (unspecified versus black), contact material (beryllium copper versus phosphor bronze), flange opening direction (side opening versus top opening), and specified card thickness (unspecified versus 0.062"). These differences do not affect functional compatibility with female edgecard interfaces.

Q: Are there any compatibility concerns with the contact material change from beryllium copper to phosphor bronze?

A: Both beryllium copper and phosphor bronze are standard contact materials for card edge connectors with gold plating. The RMC47MMSD maintains the same 30.0µin (0.76µm) gold finish thickness as the AMC47MMSD, ensuring equivalent electrical performance and contact reliability.

Q: What is the significance of the flange feature differences?

A: The AMC47MMSD features side opening with flush mount, while the RMC47MMSD features top opening with flush mount. Both configurations accommodate the same 0.100" pitch edgecard interface. The opening direction difference relates to board layout orientation and does not affect electrical function.

Q: Are both parts suitable for the same operating temperature applications?

A: Yes. Both the AMC47MMSD and RMC47MMSD operate across -65°C to 200°C, making them suitable for identical thermal environments.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
