Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC33MSST is based on the following critical parameters that define functional equivalence within the card edge connector category:

Primary Substitution Criteria:

• Connector category classification (Card Edge Connectors)
• Total position count (66 positions)
• Row configuration (2 rows)
• Contact pitch (0.100" / 2.54mm)
• Manufacturer continuity (Sullins Connector Solutions)
• Base product number alignment (AMC33 series)
• Regulatory compliance (ROHS3 Compliant, REACH Unaffected)
• Moisture sensitivity classification (MSL 1)

The RMC33MSST represents the active production equivalent within the Sullins connector portfolio, maintaining the same base product number designation (RMC33) and core electrical/mechanical specifications required for direct substitution in applications previously specified for the AMC33MSST.

Parameter Comparison

Engineering Selection Recommendations

The RMC33MSST is the designated active substitute for the obsolete AMC33MSST. Selection of the RMC33MSST is supported by the following engineering factors:

Product Status Alignment: The RMC33MSST maintains active production status, ensuring long-term procurement availability and supply chain continuity. The AMC33MSST obsolete classification restricts future sourcing options and inventory replenishment.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and hazardous substance regulations. The RMC33MSST carries EAR99 export classification, providing standard commercial export treatment.

Moisture Sensitivity: Both parts share MSL 1 classification, indicating unlimited shelf life and identical moisture handling requirements during storage and assembly operations.

Manufacturer Continuity: Both connectors originate from Sullins Connector Solutions, ensuring design consistency and manufacturing process alignment within the card edge connector product family.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC33MSST?

A: The AMC33MSST is classified as obsolete. The RMC33MSST is the active equivalent from Sullins Connector Solutions, ensuring continued availability for procurement and production applications.

Q: Are the AMC33MSST and RMC33MSST mechanically compatible?

A: Both connectors are 66-position, 2-row card edge connectors with 0.100" (2.54mm) pitch manufactured by Sullins Connector Solutions. Mechanical compatibility is established through shared base product number designation and connector category classification.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC33MSST and RMC33MSST are ROHS3 compliant and REACH unaffected, satisfying current environmental regulations.

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

A: Both parts carry MSL 1 classification, indicating unlimited shelf life with no moisture sensitivity restrictions.

Q: Are there differences in export classification between these parts?

A: The AMC33MSST carries obsolete ECCN classification. The RMC33MSST is classified as EAR99, the standard commercial export classification for electronic components.

Q: What inventory status should be considered for procurement decisions?

A: The AMC33MSST has 1054 pieces in stock as new original inventory. The RMC33MSST has 894 pieces in stock as new original inventory. However, the AMC33MSST obsolete status limits future replenishment, making the active RMC33MSST the preferred selection for ongoing production requirements.
