AMC04WWST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC04WWST is an 8-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 a dual read-out configuration with gold-plated beryllium copper contacts and operates across a temperature range of -65°C to 200°C. The AMC04WWST is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC04WWST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 8
• Gender: Male
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Positions per Bay/Row: 4
• Read Out: Dual
• 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
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RMC04MMST meets all mandatory matching parameters and is classified as an active product, making it a direct functional equivalent for the obsolete AMC04WWST.

Parameter Comparison

Engineering Selection Recommendations

The RMC04MMST is the active equivalent substitute for the obsolete AMC04WWST. Both connectors maintain identical electrical and mechanical interface specifications, including 8-position configuration, 0.100" pitch, dual read-out, and gold contact finish at 30.0µin thickness. Both parts operate across the full -65°C to 200°C temperature range and utilize PPS insulation material.

The RMC04MMST is currently in active production status with 1000 units in stock, whereas the AMC04WWST is obsolete with limited remaining inventory. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications.

The primary differences between the parts are contact material composition (beryllium copper versus phosphor bronze), mounting configuration (through hole solder termination specified for RMC04MMST), and color designation (black for RMC04MMST). These differences do not affect functional compatibility for applications requiring 8-position male card edge connectors at 0.100" pitch with dual read-out configuration.

Frequently Asked Questions (FAQ)

Q: Can the RMC04MMST directly replace the AMC04WWST in existing designs?

A: The RMC04MMST meets all critical electrical and mechanical parameters specified for the AMC04WWST, including position count, pitch, row configuration, contact finish, and operating temperature range. Both connectors interface with female edgecards using identical flange features and threaded insert specifications.

Q: What is the significance of the contact material difference between beryllium copper and phosphor bronze?

A: Both contact materials are specified with identical gold finish thickness (30.0µin) and operate across the same temperature range (-65°C to 200°C). The contact material composition is provided as specified data; selection between these materials depends on application-specific requirements not addressed in this equivalency reference.

Q: Are there compliance differences between the two parts?

A: Both the AMC04WWST and RMC04MMST maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: What is the significance of the card thickness specification for the RMC04MMST?

A: The RMC04MMST specifies a card thickness of 0.062" (1.57mm). This parameter is provided for the substitute part but is not specified for the main part. Both connectors are designed to fit female edgecards at 0.100" pitch with identical flange configurations.

Q: Why is the AMC04WWST classified as obsolete?

A: The AMC04WWST is listed with obsolete product status. The RMC04MMST, classified as active, represents the current production equivalent from Sullins Connector Solutions for 8-position male card edge connectors at 0.100" pitch.

Q: Are there inventory considerations for part selection?

A: The RMC04MMST has 1000 units in stock as new original inventory. The AMC04WWST has 975 units remaining in stock but is obsolete. For new designs and ongoing production, the RMC04MMST is the recommended active equivalent.
