AMC37MMST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC37MMST is a 74-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 AMC37MMST 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 AMC37MMST with the active RMC37MMST is based on alignment of critical electrical and mechanical parameters that define functional compatibility in card edge connector applications. The substitute part maintains identical specifications across the following key parameters:

• Position Count & Pitch: Both connectors provide 74 positions at 0.100" (2.54mm) pitch
• Connector Gender & Configuration: Both are male connectors with dual read-out and 2-row configuration
• Card Interface: Both fit female edgecards
• Termination Method: Both utilize solder termination
• Contact Finish: Both feature gold plating at 30.0µin (0.76µm) thickness
• Operating Temperature: Both operate across -65°C to 200°C
• Insulation Material: Both use Polyphenylene Sulfide (PPS)
• Mounting Flange: Both feature flush mount with top opening and 4-40 threaded insert
• Compliance: Both are ROHS3 compliant with MSL 1 rating

The RMC37MMST represents the active production equivalent, with documented inventory availability and current product status.

Parameter Comparison

Engineering Selection Recommendations

The RMC37MMST is the direct active equivalent for the obsolete AMC37MMST. Both connectors maintain identical electrical and mechanical specifications across all critical parameters that define card edge connector functionality. The RMC37MMST is currently in active production status with documented inventory availability of 794 pieces.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The contact material differs between the two parts (beryllium copper versus phosphor bronze); however, both materials provide equivalent performance within the specified operating temperature range of -65°C to 200°C with identical gold plating thickness of 30.0µin (0.76µm).

The RMC37MMST includes specified card thickness of 0.062" (1.57mm) and through-hole mounting type, with black color designation. These parameters define the physical implementation characteristics for the active substitute part.

Frequently Asked Questions (FAQ)

Q: Can the RMC37MMST directly replace the AMC37MMST in existing designs?

A: Yes. Both connectors maintain identical position count (74), pitch (0.100"), gender (male), row configuration (2), card interface type (fits female edgecards), read-out configuration (dual), termination method (solder), contact finish (gold at 30.0µin), operating temperature range (-65°C to 200°C), insulation material (PPS), and flange features (flush mount, top opening, 4-40 threaded insert).

Q: What is the difference in contact material between these two parts?

A: The AMC37MMST uses beryllium copper contacts, while the RMC37MMST uses phosphor bronze contacts. Both materials provide equivalent electrical and mechanical performance within the specified operating temperature range with identical gold plating thickness.

Q: Are there compliance differences between the two parts?

A: No. Both the AMC37MMST and RMC37MMST are ROHS3 compliant with MSL 1 (unlimited) rating and REACH unaffected status.

Q: What is the card thickness specification for the RMC37MMST?

A: The RMC37MMST is specified for 0.062" (1.57mm) card thickness. The AMC37MMST does not include a specified card thickness parameter.

Q: What mounting type does the RMC37MMST use?

A: The RMC37MMST uses through-hole mounting. The AMC37MMST does not include a specified mounting type parameter.

Q: Is the RMC37MMST currently available?

A: Yes. The RMC37MMST is in active product status with 794 pieces in stock as new original inventory.
