AMC46MMST Equivalent & Substitute Parts

Part Overview

The AMC46MMST is a 92-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 the temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility with existing applications.

Pitch: 0.100" (2.54mm)
Number of rows: 2
Read out: Dual
Termination: Solder
Contact finish: Gold (30.0µin thickness)
Operating temperature range: -65°C ~ 200°C
Insulation material: Polyphenylene Sulfide (PPS)
Flange feature: Flush Mount, Top Opening, Threaded Insert, 4-40
RoHS compliance: ROHS3 Compliant
Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

Contact material: Beryllium Copper (AMC46MMST) vs. Phosphor Bronze (RMC46MMST)
Card thickness specification: Not specified (AMC46MMST) vs. 0.062" (1.57mm) (RMC46MMST)
Mounting type: Not specified (AMC46MMST) vs. Through Hole (RMC46MMST)
Color: Not specified (AMC46MMST) vs. Black (RMC46MMST)
Product status: Obsolete (AMC46MMST) vs. Active (RMC46MMST)

The RMC46MMST maintains all critical electrical and mechanical interface parameters required for functional compatibility with female edgecards designed for the AMC46MMST.

Engineering Selection Recommendations

The RMC46MMST serves as the direct active equivalent for the obsolete AMC46MMST. Both connectors maintain identical electrical interface specifications, including 92-position configuration, 0.100" pitch, dual read-out, and solder termination. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

The transition from the obsolete AMC46MMST to the active RMC46MMST is supported by:

Identical connector geometry and pin configuration
Matching operating temperature range (-65°C to 200°C)
Equivalent contact finish specification (gold, 30.0µin)
Identical insulation material (Polyphenylene Sulfide)
Matching flange and mounting interface (Flush Mount, Top Opening, Threaded Insert, 4-40)
Active product status with current manufacturing availability

The RMC46MMST is suitable for direct substitution in applications currently utilizing the AMC46MMST, with no redesign of mating interfaces required.

Frequently Asked Questions (FAQ)

Q: Can the RMC46MMST directly replace the AMC46MMST in existing designs?

A: Yes. The RMC46MMST maintains identical electrical and mechanical interface parameters with the AMC46MMST. The 92-position configuration, 0.100" pitch, dual read-out, and flange geometry are equivalent. No PCB or connector redesign is required.

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

A: The AMC46MMST uses beryllium copper contacts, while the RMC46MMST uses phosphor bronze contacts. Both materials are plated with gold at 30.0µin thickness and operate across the same temperature range (-65°C to 200°C).

Q: Does the RMC46MMST specify a card thickness?

A: Yes. The RMC46MMST is specified for 0.062" (1.57mm) card thickness. The AMC46MMST does not include a card thickness specification in the provided data.

Q: Are both connectors RoHS compliant?

A: Yes. Both the AMC46MMST and RMC46MMST are ROHS3 compliant and carry REACH Unaffected status.

Q: What is the moisture sensitivity level for the RMC46MMST?

A: The RMC46MMST carries Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.

Q: Why is the AMC46MMST classified as obsolete?

A: The AMC46MMST is listed as obsolete by the manufacturer. The RMC46MMST is the active equivalent and is currently in production with 673 pieces available in stock.
