AMC14MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC14MMSD is a 28-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards using a 0.100" (2.54mm) pitch. This connector features dual read-out configuration with gold-plated beryllium copper contacts and operates across a temperature range of -65°C to 200°C.

The AMC14MMSD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and replacement requirements for legacy systems utilizing this connector type.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC14MMSD with the active RMC14MMSD is based on the following critical parameters that must align for functional compatibility:

Core Compatibility Parameters:

Number of positions: 28 positions maintained
Pitch specification: 0.100" (2.54mm) maintained
Read out configuration: Dual maintained
Termination method: Solder maintained
Contact finish: Gold plating maintained at 30.0µin (0.76µm)
Operating temperature range: -65°C to 200°C maintained
Insulation material: Polyphenylene Sulfide (PPS) maintained
Flange diameter: 0.125" (3.18mm) maintained
Compliance certifications: ROHS3 Compliant and REACH Unaffected maintained

Parameters with Variations:

Contact material: Beryllium Copper (AMC14MMSD) versus Phosphor Bronze (RMC14MMSD)
Flange opening orientation: Side Opening (AMC14MMSD) versus Top Opening (RMC14MMSD)
Card thickness specification: Not specified (AMC14MMSD) versus 0.062" (1.57mm) (RMC14MMSD)
Mounting type: Not specified (AMC14MMSD) versus Through Hole (RMC14MMSD)
Color: Not specified (AMC14MMSD) versus Black (RMC14MMSD)

The RMC14MMSD maintains all critical electrical and mechanical parameters required for card edge connector functionality while offering active product status and current availability.

Engineering Selection Recommendations

The RMC14MMSD is the direct active substitute for the obsolete AMC14MMSD. Both connectors maintain identical electrical specifications, pitch, position count, and temperature operating range. Both components satisfy ROHS3 compliance and REACH requirements.

The RMC14MMSD offers the advantage of active product status with current manufacturing and availability. The connector maintains all critical parameters necessary for card edge interface applications, including dual read-out configuration, solder termination, and gold contact plating.

Selection of the RMC14MMSD eliminates obsolescence risk while preserving functional compatibility with existing female edgecard designs that operate at 0.100" (2.54mm) pitch with 28-position dual-row configuration.

Frequently Asked Questions (FAQ)

Q: Can the RMC14MMSD directly replace the AMC14MMSD in existing applications?

A: The RMC14MMSD maintains all critical electrical and mechanical parameters required for card edge connector functionality. Both connectors feature 28 positions at 0.100" pitch, dual read-out configuration, solder termination, and identical operating temperature range. The substitute part is compatible with female edgecards designed for the original AMC14MMSD.

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

A: The AMC14MMSD uses beryllium copper contacts, while the RMC14MMSD uses phosphor bronze contacts. Both materials are plated with gold at 30.0µin thickness and provide equivalent electrical performance for card edge connector applications.

Q: How do the flange opening orientations differ?

A: The AMC14MMSD features side opening flange configuration, while the RMC14MMSD features top opening flange configuration. Both maintain the same 0.125" (3.18mm) diameter and flush mount design. The opening orientation difference does not affect electrical compatibility with standard female edgecards.

Q: What is the specified card thickness for the RMC14MMSD?

A: The RMC14MMSD is specified for 0.062" (1.57mm) card thickness. This specification ensures proper contact engagement with edgecards of this thickness.

Q: Are both connectors RoHS compliant?

A: Yes, both the AMC14MMSD and RMC14MMSD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

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

A: Both connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
