AMC48MWST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC48MWST is a 96-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 beryllium copper contacts finished in gold and operates across a temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure procurement availability for new production and field service applications.

Substitute Part Grouping Explanation

The RMC48MWST serves as a direct manufacturer substitute for the obsolete AMC48MWST. Both connectors are manufactured by Sullins Connector Solutions and share the same base product number family (AMC48 and RMC48 respectively). The substitution is valid based on the following critical parameters that determine functional equivalence:

Key Parameters for Substitution Validity:

• Manufacturer: Sullins Connector Solutions (consistent source)
• Number of Positions: 96 positions
• Number of Rows: 2 rows
• Pitch: 0.100" (2.54mm)
• Gender: Male connector configuration
• Contact Material: Beryllium Copper
• Contact Finish: Gold plating
• RoHS Compliance: ROHS3 Compliant (both parts)
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected (both parts)

The RMC48MWST is classified as an active product, providing current manufacturing support and procurement availability, whereas the AMC48MWST is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The RMC48MWST is the appropriate substitute for the obsolete AMC48MWST based on the following engineering criteria:

Product Status and Availability: The AMC48MWST is classified as obsolete, limiting long-term procurement viability. The RMC48MWST maintains active product status with current manufacturing support from Sullins Connector Solutions, ensuring supply chain continuity.

Regulatory Compliance: Both connectors maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement.

Electrical and Mechanical Compatibility: The RMC48MWST matches the critical electrical and mechanical parameters of the AMC48MWST, including 96-position configuration, 2-row layout, 0.100" pitch, male gender, beryllium copper contacts with gold finish, and MSL 1 rating.

Manufacturer Consistency: Both parts originate from Sullins Connector Solutions, ensuring design continuity and manufacturing process alignment.

For applications requiring the specific operating temperature range (-65°C ~ 200°C) or PPS insulation material of the original AMC48MWST, direct confirmation with Sullins Connector Solutions is necessary to validate that the RMC48MWST maintains these specifications.

Frequently Asked Questions (FAQ)

Q: Can the RMC48MWST directly replace the AMC48MWST in existing designs?

A: The RMC48MWST shares the critical electrical and mechanical parameters with the AMC48MWST, including connector type, position count, pitch, contact material, and finish. Both parts are ROHS3 compliant and MSL 1 rated. Substitution is valid for applications where the specified parameters are the determining factors for compatibility.

Q: What is the primary reason for substituting the AMC48MWST?

A: The AMC48MWST is classified as obsolete, which restricts procurement availability and manufacturing support. The RMC48MWST is an active product from the same manufacturer, providing current supply chain access and ongoing technical support.

Q: Are there any differences in contact finish specifications between these connectors?

A: The AMC48MWST specifies a contact finish thickness of 30.0µin (0.76µm). The RMC48MWST contact finish thickness is not provided in the available technical data. Confirmation of this specification should be obtained from Sullins Connector Solutions if finish thickness is critical to the application.

Q: Do both connectors operate across the same temperature range?

A: The AMC48MWST operates from -65°C to 200°C. The operating temperature range for the RMC48MWST is not specified in the available technical data. Applications requiring operation at these temperature extremes should be confirmed with the manufacturer.

Q: What is the insulation material for the RMC48MWST?

A: The AMC48MWST uses Polyphenylene Sulfide (PPS) insulation. The insulation material for the RMC48MWST is not specified in the available technical data. If PPS insulation is a design requirement, confirmation should be obtained from Sullins Connector Solutions.

Q: Are both connectors compliant with current environmental regulations?

A: Yes. Both the AMC48MWST and RMC48MWST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: What is the MSL rating for the RMC48MWST?

A: The RMC48MWST carries an MSL rating of 1 (Unlimited), matching the AMC48MWST. This indicates unlimited shelf life under normal storage conditions without moisture sensitivity concerns.
