AMC12MMST Equivalent & Substitute Parts

Part Overview

The AMC12MMST is a 24-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 currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility with existing female edgecard receptacles.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC12MMST with the RMC12MMST is based on alignment of critical electrical and mechanical parameters that ensure functional compatibility with existing female edgecard receptacles. The substitute part maintains identical specifications for the following parameters: 24-position count, 0.100" (2.54mm) pitch, male gender, dual read-out configuration, solder termination, gold contact finish, -65°C to 200°C operating temperature range, PPS insulation material, and identical flange geometry (flush mount, top opening, threaded insert, 4-40).

The RMC12MMST differs from the AMC12MMST in the following attributes: contact material (phosphor bronze versus beryllium copper), card thickness specification (0.062" specified versus unspecified), mounting type designation (through hole versus unspecified), color (black versus unspecified), and product status (active versus obsolete). These differences do not affect mechanical or electrical compatibility with standard female edgecard interfaces operating at 0.100" pitch.

Parameter Comparison

Engineering Selection Recommendations

The RMC12MMST serves as the direct active equivalent for the obsolete AMC12MMST. Both connectors are manufactured by Sullins Connector Solutions and maintain identical mechanical and electrical interface specifications for 24-position, 0.100" pitch male card edge connections. Both parts are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

The RMC12MMST is currently in active production status with 1135 units in stock, whereas the AMC12MMST is obsolete. For new designs or replacement applications requiring 24-position male card edge connectors at 0.100" pitch with dual read-out and solder termination, the RMC12MMST is the appropriate selection. The substitute part maintains full compatibility with existing female edgecard receptacles designed for 0.100" pitch male connectors.

Frequently Asked Questions (FAQ)

Q: Will the RMC12MMST physically fit into female edgecards designed for the AMC12MMST?

A: Yes. Both connectors share identical pitch (0.100"), position count (24), row configuration (2 rows), and flange geometry (flush mount, top opening, threaded insert, 4-40). The male connector interface is mechanically compatible with standard female edgecard receptacles.

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

A: The AMC12MMST uses beryllium copper contacts while the RMC12MMST uses phosphor bronze contacts. Both materials are suitable for card edge connector applications and are gold-plated with identical finish thickness (30.0µin). The contact material difference does not affect electrical compatibility with female edgecard receptacles.

Q: Are both connectors suitable for the same operating temperature range?

A: Yes. Both the AMC12MMST and RMC12MMST operate across -65°C to 200°C, providing identical thermal performance specifications.

Q: What does "dual read-out" mean in the context of these connectors?

A: Dual read-out indicates that the connector provides two independent signal paths or contact sets, allowing simultaneous connection to two separate circuits or providing redundant contact paths for reliability.

Q: Is the RMC12MMST available in stock?

A: Yes. The RMC12MMST has 1135 units in stock as new original inventory, whereas the obsolete AMC12MMST has 818 units remaining.

Q: Do both connectors meet current regulatory compliance standards?

A: Yes. Both the AMC12MMST and RMC12MMST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the card thickness specification for the RMC12MMST?

A: The RMC12MMST is specified for 0.062" (1.57mm) card thickness. This specification ensures proper contact engagement with edgecards of this thickness.
