AMC30MMST Equivalent & Substitute Parts

Part Overview

The AMC30MMST is a 60-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 electrical and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC30MMST with the active RMC30MMST is based on alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Identical position count (60 positions, 30 per row, 2 rows)
• Matching pitch specification (0.100" / 2.54mm)
• Dual read-out configuration maintained
• Gold contact finish with identical thickness (30.0µin)
• Solder termination type preserved
• Identical operating temperature range (-65°C ~ 200°C)
• Matching insulation material (PPS)

Mechanical Compatibility Parameters:

• Identical flange feature configuration (Flush Mount, Top Opening, Threaded Insert, 4-40)
• Both designed for female edgecards
• Male gender maintained

Compliance Parameters:

• ROHS3 compliance maintained
• MSL 1 (Unlimited) rating preserved
• REACH Unaffected status maintained

Noted Differences:

• Contact material differs (Beryllium Copper vs. Phosphor Bronze)
• Card thickness specification provided for substitute (0.062" / 1.57mm)
• Mounting type specified for substitute (Through Hole)
• Color designation added for substitute (Black)
• Product status transitions from Obsolete to Active

Engineering Selection Recommendations

The RMC30MMST serves as the direct active equivalent for the obsolete AMC30MMST. Selection of the RMC30MMST is supported by the following engineering criteria:

Product Status Alignment: The RMC30MMST maintains active product status with current manufacturing and inventory availability (831 pcs in stock), eliminating supply chain risk associated with the obsolete AMC30MMST.

Electrical and Mechanical Compatibility: All critical electrical parameters are preserved: 60-position configuration, 0.100" pitch, dual read-out, gold contact finish at 30.0µin thickness, solder termination, and -65°C to 200°C operating range. Mechanical compatibility is maintained through identical flange configuration (Flush Mount, Top Opening, Threaded Insert, 4-40) and male gender for female edgecard interface.

Compliance Certification: Both parts maintain ROHS3 compliance, MSL 1 (Unlimited) rating, and REACH Unaffected status, ensuring regulatory alignment for current and future applications.

Material and Configuration Differences: The RMC30MMST specifies Phosphor Bronze contacts in place of Beryllium Copper, with explicit card thickness (0.062") and Through Hole mounting designation. These specifications define the operating envelope for the substitute part and do not preclude functional equivalence in applications designed for the original AMC30MMST.

Frequently Asked Questions (FAQ)

Q: Can the RMC30MMST directly replace the AMC30MMST in existing designs?

A: The RMC30MMST is electrically and mechanically compatible with the AMC30MMST. Both connectors share identical position count (60), pitch (0.100"), read-out configuration (Dual), contact finish (Gold, 30.0µin), termination method (Solder), operating temperature range (-65°C ~ 200°C), and flange configuration. The RMC30MMST is the active equivalent for the obsolete AMC30MMST.

Q: What is the significance of the contact material difference between Beryllium Copper and Phosphor Bronze?

A: Both contact materials are specified for the respective parts. The contact material is a defined characteristic of each connector model. The RMC30MMST uses Phosphor Bronze contacts, which is the specified material for this part number.

Q: Does the RMC30MMST card thickness specification (0.062") affect compatibility?

A: The card thickness specification (0.062" / 1.57mm) defines the mechanical envelope for the RMC30MMST. This specification is provided for the substitute part and represents the design parameter for this connector model.

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

A: Both the AMC30MMST and RMC30MMST operate across the identical temperature range of -65°C to 200°C, ensuring thermal compatibility for applications within this specification.

Q: What is the difference between the mounting type designations?

A: The AMC30MMST does not specify a mounting type parameter. The RMC30MMST specifies Through Hole mounting, which defines the termination method for this connector model.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain identical compliance status: ROHS3 Compliant, MSL 1 (Unlimited), and REACH Unaffected. No compliance differences exist between the AMC30MMST and RMC30MMST.

Q: Why is the AMC30MMST classified as obsolete?

A: The AMC30MMST is listed with obsolete product status. The RMC30MMST is the active equivalent, currently manufactured and stocked (831 pcs available), providing continuity for applications requiring 60-position male card edge connectors at 0.100" pitch.
