AMC29MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC29MMSD is a 58-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 with gold-plated beryllium copper contacts and operates across the temperature range of -65°C to 200°C.

The AMC29MMSD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC29MMSD is evaluated based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• Number of positions (58 total, 29 per row, 2 rows)
• Pitch specification (0.100" / 2.54mm)
• Read out configuration (Dual)
• Termination method (Solder)
• Contact finish specification (Gold, 30.0µin)
• Operating temperature range (-65°C to 200°C)
• Insulation material (Polyphenylene Sulfide)
• Compliance certifications (ROHS3, REACH)

Parameters Permitting Variation:

• Contact material (Beryllium Copper vs. Phosphor Bronze)
• Flange opening orientation (Side Opening vs. Top Opening)
• Connector color
• Card thickness specification
• Mounting type classification
• Product status (Obsolete vs. Active)

The RMC29MMSD satisfies all core compatibility parameters while introducing controlled variations in contact material, flange design, and mounting configuration that remain within acceptable substitution criteria for card edge connector applications.

Parameter Comparison

Engineering Selection Recommendations

The RMC29MMSD is an active-status substitute for the obsolete AMC29MMSD. Both connectors are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical specifications for the critical parameters governing card edge connector functionality: position count, pitch, read-out configuration, termination method, contact finish, operating temperature range, and insulation material.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

The RMC29MMSD offers the advantage of active product status, ensuring continued availability and manufacturing support. The contact material variation (Phosphor Bronze in the substitute versus Beryllium Copper in the original) and flange opening orientation (Top Opening versus Side Opening) represent design refinements that do not compromise functional compatibility within card edge connector applications.

Selection of the RMC29MMSD as a substitute for the AMC29MMSD is supported by equivalent electrical performance, identical pitch and position specifications, matching termination and contact finish characteristics, and compliance with applicable regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the RMC29MMSD directly replace the AMC29MMSD in existing applications?

A: The RMC29MMSD maintains identical electrical specifications and mechanical pitch with the AMC29MMSD. Both connectors feature 58 positions at 0.100" pitch, dual read-out configuration, solder termination, and gold contact finish. The substitute part is compatible with female edgecards designed for the original connector.

Q: What is the significance of the contact material difference between the two parts?

A: The AMC29MMSD uses beryllium copper contacts, while the RMC29MMSD uses phosphor bronze contacts. Both materials provide equivalent electrical conductivity and contact reliability for card edge connector applications. Phosphor bronze is a standard alternative contact material in modern connector designs.

Q: How do the flange opening orientations differ?

A: The AMC29MMSD features side opening flange design, while the RMC29MMSD features top opening flange design. Both maintain flush mount configuration with 0.125" diameter unthreaded flanges. The opening orientation difference accommodates different PCB layout and assembly approaches without affecting electrical function.

Q: Why is the RMC29MMSD listed as active status while the AMC29MMSD is obsolete?

A: The RMC29MMSD represents the current production equivalent within the Sullins connector portfolio. Active status indicates ongoing manufacturing availability and technical support. The AMC29MMSD has been discontinued from production, making the active substitute necessary for new procurement and long-term supply chain planning.

Q: Are both parts compliant with current regulatory requirements?

A: Both the AMC29MMSD and RMC29MMSD are ROHS3 compliant and REACH unaffected. Both parts satisfy current regulatory standards for electronic component manufacturing and use.

Q: What is the specified card thickness for each connector?

A: The AMC29MMSD does not specify card thickness in its technical parameters. The RMC29MMSD specifies 0.062" (1.57mm) card thickness. Both connectors are designed to interface with female edgecards at 0.100" pitch spacing.

Q: Is the through-hole mounting type of the RMC29MMSD compatible with applications using the AMC29MMSD?

A: The RMC29MMSD is classified as through-hole mounting type. Both connectors use solder termination for PCB attachment. The mounting type designation reflects the connector's physical design for through-hole PCB assembly, which is compatible with standard solder attachment methods used in legacy and current applications.
