AMC35MMST Equivalent & Substitute Parts

Part Overview

The AMC35MMST is a 70-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 for ongoing procurement and system integration.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC35MMST is based on electrical and mechanical compatibility within the card edge connector category. The primary substitute, RMC35MMST, maintains functional equivalence through identical core parameters: 70-position configuration, 0.100" pitch, dual read-out, male gender, 2-row arrangement, solder termination, gold contact finish at 30.0µin thickness, -65°C to 200°C operating range, PPS insulation material, and identical flange specifications (flush mount, top opening, threaded insert 4-40).

Substitution is valid when the following parameters align:

• Number of Positions: 70
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Number of Rows: 2
• Read Out: Dual
• Termination: Solder
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Operating Temperature Range: -65°C ~ 200°C
• Insulation Material: Polyphenylene Sulfide (PPS)
• Flange Feature: Flush Mount, Top Opening, Threaded Insert, 4-40

Parameter Comparison

Engineering Selection Recommendations

The RMC35MMST serves as the direct active substitute for the obsolete AMC35MMST. Both connectors are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical specifications across all critical parameters: 70-position configuration, 0.100" pitch, dual read-out, solder termination, gold contact finish at 30.0µin thickness, -65°C to 200°C operating range, PPS insulation, and identical flange geometry.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility. The RMC35MMST is currently in active production status, providing assured long-term availability compared to the obsolete AMC35MMST.

The contact material differs between the two parts: AMC35MMST uses beryllium copper while RMC35MMST uses phosphor bronze. Both materials are suitable for gold-plated card edge connector applications and maintain equivalent electrical performance within the specified operating parameters.

The RMC35MMST provides additional specification clarity through documented card thickness (0.062"), through-hole mounting type, and black color designation, which were not specified for the AMC35MMST.

Frequently Asked Questions (FAQ)

Q: Can RMC35MMST directly replace AMC35MMST in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications across all critical parameters: 70 positions, 0.100" pitch, dual read-out, male gender, 2-row configuration, solder termination, gold contact finish, -65°C to 200°C operating range, PPS insulation, and flush mount flange with threaded insert 4-40. Both maintain ROHS3 compliance and MSL 1 rating.

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

A: AMC35MMST uses beryllium copper contacts while RMC35MMST uses phosphor bronze contacts. Both materials are suitable for gold-plated card edge connector applications and deliver equivalent electrical performance within the specified operating parameters.

Q: Does the RMC35MMST specify card thickness compatibility?

A: Yes. RMC35MMST is specified for 0.062" (1.57mm) card thickness. The AMC35MMST does not document this specification. Verify that your edgecard thickness matches the 0.062" specification for the RMC35MMST.

Q: Are both connectors compliant with current regulatory standards?

A: Yes. Both AMC35MMST and RMC35MMST are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The RMC35MMST additionally carries REACH Unaffected status and EAR99 ECCN classification.

Q: What is the availability difference between these parts?

A: AMC35MMST is classified as obsolete with 986 pieces in stock. RMC35MMST is in active production status with 811 pieces in stock, providing assured long-term procurement availability.

Q: Does the color difference between the connectors affect functionality?

A: No. The RMC35MMST black color designation is a cosmetic specification that does not affect electrical or mechanical performance. Both connectors maintain identical functional characteristics.
