AMC09MMST Equivalent & Substitute Parts

Part Overview

The AMC09MMST 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, gold-plated beryllium copper contacts, and operates across -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility with existing female edgecard interfaces.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC09MMST with the active RMC09MMST is based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• 18-position configuration with dual read-out
• 0.100" (2.54mm) pitch spacing
• Male gender for female edgecard interface
• 2-row arrangement
• Solder termination
• Gold contact finish at 30.0µin thickness
• Flush mount with top opening and 4-40 threaded insert
• Operating temperature range -65°C to 200°C
• Polyphenylene Sulfide (PPS) insulation material
• ROHS3 compliance and MSL 1 rating

Differing Parameters:

• Contact material: Beryllium copper (AMC09MMST) versus Phosphor bronze (RMC09MMST)
• Card thickness specification: Not specified (AMC09MMST) versus 0.062" (1.57mm) (RMC09MMST)
• Mounting type: Not specified (AMC09MMST) versus Through Hole (RMC09MMST)
• Color: Not specified (AMC09MMST) versus Black (RMC09MMST)
• Product status: Obsolete (AMC09MMST) versus Active (RMC09MMST)

The RMC09MMST maintains all critical electrical and mechanical parameters required for direct substitution in female edgecard applications while offering active product status and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The RMC09MMST is the direct active equivalent for the obsolete AMC09MMST. Selection of the RMC09MMST is supported by the following factors:

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and deployment environments.

Product Status: The RMC09MMST holds active product status with current manufacturing support from Sullins Connector Solutions, whereas the AMC09MMST is classified as obsolete and subject to discontinuation.

Electrical and Mechanical Compatibility: The RMC09MMST preserves all critical interface parameters including 18-position configuration, 0.100" pitch, dual read-out, solder termination, gold contact finish, and operating temperature range. These parameters ensure functional compatibility with existing female edgecard designs.

Contact Material Difference: The RMC09MMST employs phosphor bronze contacts in place of beryllium copper. Both materials provide suitable electrical conductivity and mechanical durability for card edge connector applications at the specified operating temperature range.

Inventory Availability: The RMC09MMST maintains active inventory status with 739 units in stock, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the RMC09MMST directly replace the AMC09MMST in existing designs?

A: Yes. The RMC09MMST maintains all critical electrical and mechanical parameters required for direct substitution. Both connectors feature 18 positions, 0.100" pitch, dual read-out, solder termination, gold contact finish, and identical operating temperature range. The connector interfaces with female edgecards using the same flush mount, top opening, 4-40 threaded insert configuration.

Q: What is the difference between beryllium copper and phosphor bronze contacts?

A: Both materials provide electrical conductivity and mechanical durability suitable for card edge connector applications. Beryllium copper (AMC09MMST) and phosphor bronze (RMC09MMST) are both established contact materials for this connector category. The phosphor bronze contacts in the RMC09MMST perform within the specified operating temperature range of -65°C to 200°C.

Q: Does the RMC09MMST specify a card thickness?

A: Yes. The RMC09MMST is specified for 0.062" (1.57mm) card thickness. The original AMC09MMST does not include a card thickness specification. Verify that existing female edgecards conform to this thickness specification for proper mechanical fit.

Q: Are there any differences in mounting between the two parts?

A: The RMC09MMST specifies through-hole mounting, while the AMC09MMST does not include a mounting type specification. Both parts feature the same flush mount, top opening, 4-40 threaded insert flange configuration for mechanical attachment.

Q: What is the significance of the black color on the RMC09MMST?

A: The black color is a cosmetic specification of the RMC09MMST insulation material. This does not affect electrical or mechanical performance. The original AMC09MMST does not specify a color. Both parts use Polyphenylene Sulfide (PPS) insulation material.

Q: Are both parts RoHS compliant?

A: Yes. Both the AMC09MMST and RMC09MMST are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and deployment.

Q: What is the MSL rating and why is it important?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. This allows storage and handling without special moisture control measures, simplifying inventory management and procurement logistics.
