AMC17MMST Equivalent & Substitute Parts

Part Overview

The AMC17MMST is a 34-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 while ensuring continued supply availability and compliance with current regulatory standards.

• Gender: Male
• Card type: Fits Female Edgecards
• Read out: Dual
• Contact finish: Gold
• Contact finish thickness: 30.0µin (0.76µm)
• Termination: Solder
• Operating temperature range: -65°C ~ 200°C
• Insulation material: Polyphenylene Sulfide (PPS)
• Flange feature: Flush Mount, Top Opening, Threaded Insert, 4-40
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

• Contact material: Beryllium Copper (AMC17MMST) vs. Phosphor Bronze (RMC17MMST)
• Card thickness specification: Not specified (AMC17MMST) vs. 0.062" (1.57mm) (RMC17MMST)
• Mounting type: Not specified (AMC17MMST) vs. Through Hole (RMC17MMST)
• Color: Not specified (AMC17MMST) vs. Black (RMC17MMST)
• Product status: Obsolete (AMC17MMST) vs. Active (RMC17MMST)

The RMC17MMST maintains all critical electrical and mechanical parameters required for functional equivalence in card edge connector applications while offering active product status and current regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The RMC17MMST serves as the direct active equivalent for the obsolete AMC17MMST. Selection of the RMC17MMST is supported by the following engineering criteria:

Regulatory Compliance: Both connectors maintain ROHS3 compliance and REACH unaffected status, ensuring adherence to current environmental and hazardous substance regulations.

Functional Equivalence: The RMC17MMST preserves all critical electrical and mechanical parameters including position count, pitch, gender, read-out configuration, contact finish specification, termination method, and operating temperature range.

Product Availability: The RMC17MMST holds active product status with 910 units in stock, providing supply continuity for applications currently utilizing the obsolete AMC17MMST.

Contact Material Difference: The RMC17MMST employs phosphor bronze contacts in place of beryllium copper. Both materials provide suitable electrical conductivity and mechanical durability for card edge connector applications at the specified operating temperature range and contact finish thickness.

Mechanical Specifications: The RMC17MMST specifies 0.062" (1.57mm) card thickness and through-hole mounting type, providing defined mechanical parameters for design integration.

Frequently Asked Questions (FAQ)

Q: Can the RMC17MMST directly replace the AMC17MMST in existing applications?

A: The RMC17MMST maintains all critical electrical and mechanical parameters required for functional equivalence. The connector interfaces with female edgecards at identical pitch and position configuration, operates across the same temperature range, and provides equivalent contact finish specifications. Integration into existing designs requires verification that the specified 0.062" (1.57mm) card thickness and through-hole mounting type align with application requirements.

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

A: Both beryllium copper and phosphor bronze provide suitable electrical conductivity and mechanical durability for card edge connector applications. The contact material difference does not affect the electrical interface characteristics or operating temperature performance within the specified range. Both materials support the 30.0µin (0.76µm) gold contact finish thickness.

Q: Are there compliance differences between the two connectors?

A: Both the AMC17MMST and RMC17MMST maintain ROHS3 compliance and REACH unaffected status. No compliance differentiation exists between the two parts.

Q: What does the card thickness specification of 0.062" (1.57mm) indicate?

A: The card thickness specification defines the mechanical tolerance range for female edgecards that interface with the RMC17MMST connector. This specification ensures proper contact engagement and mechanical stability during mating operations.

Q: Why is the AMC17MMST classified as obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued production and support for this part number. The RMC17MMST represents the active equivalent offering continued supply and manufacturer support.

Q: Does the black color of the RMC17MMST affect electrical performance?

A: Color is a cosmetic specification that does not affect electrical performance, contact characteristics, or functional compatibility. The black color designation applies to the insulation material appearance only.
