AMC25MMST Equivalent & Substitute Parts

Part Overview

The AMC25MMST is a 50-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 AMC25MMST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 50
• Gender: Male
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Read Out: Dual
• Termination: Solder
• Operating Temperature Range: -65°C ~ 200°C
• Material - Insulation: Polyphenylene Sulfide (PPS)
• Flange Feature: Flush Mount, Top Opening, Threaded Insert, 4-40
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RMC25MMST meets all mandatory matching parameters and is classified as an active product, making it a direct functional equivalent for the obsolete AMC25MMST in applications requiring 50-position male card edge connectors with dual read-out and gold-plated contacts.

Parameter Comparison

Engineering Selection Recommendations

The RMC25MMST is the direct active equivalent for the obsolete AMC25MMST. Both connectors are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical specifications across all critical interface parameters: 50-position configuration, 0.100" pitch, dual read-out, solder termination, and operating temperature range of -65°C to 200°C.

Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard manufacturing and storage protocols. The RMC25MMST is currently in active production status, providing assured supply availability for new designs and replacement applications.

The contact material differs between the two parts (beryllium copper versus phosphor bronze); however, both materials with gold plating at 30.0µin thickness meet the functional requirements for card edge connector applications. The RMC25MMST includes specified card thickness of 0.062" (1.57mm) and through-hole mounting type, providing additional design clarity for PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the RMC25MMST directly replace the AMC25MMST in existing designs?

A: Yes. The RMC25MMST maintains identical electrical and mechanical specifications across all critical parameters: 50-position configuration, 0.100" pitch, dual read-out, solder termination, gold contact finish, and -65°C to 200°C operating temperature range. Both connectors interface with the same female edgecard specifications.

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

A: The AMC25MMST uses beryllium copper contacts, while the RMC25MMST uses phosphor bronze contacts. Both materials are plated with 30.0µin gold finish. Both contact materials are suitable for card edge connector applications with equivalent electrical performance.

Q: Are both connectors RoHS compliant?

A: Yes. Both the AMC25MMST and RMC25MMST are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the specified card thickness for the RMC25MMST?

A: The RMC25MMST is specified for 0.062" (1.57mm) card thickness. The AMC25MMST does not include a specified card thickness parameter in the provided data.

Q: What mounting type does the RMC25MMST use?

A: The RMC25MMST uses through-hole mounting. Both connectors feature flush mount, top opening, threaded insert configuration with 4-40 threads.

Q: Is the RMC25MMST currently available?

A: Yes. The RMC25MMST is classified as an active product with current inventory availability, unlike the obsolete AMC25MMST.
