AMC60MMST Equivalent & Substitute Parts

Part Overview

The AMC60MMST is a 120-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 to maintain design continuity and ensure component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC60MMST is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Number of positions: 120 (60 per row, 2 rows)
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Card type: Fits female edgecards
• Read out: Dual
• Contact finish: Gold at 30.0µin (0.76µm)
• Termination: Solder

Mechanical Compatibility Criteria:

• Flange feature: Flush mount, top opening, threaded insert, 4-40
• Operating temperature: -65°C ~ 200°C
• Insulation material: Polyphenylene Sulfide (PPS)

Compliance Criteria:

• RoHS3 compliance
• MSL 1 (unlimited moisture sensitivity)

The RMC60MMST meets all electrical and mechanical compatibility requirements while maintaining full regulatory compliance. Differences in contact material (phosphor bronze vs. beryllium copper), card thickness specification, color designation, and mounting type classification do not affect functional interchangeability in applications designed for the AMC60MMST.

Parameter Comparison

Engineering Selection Recommendations

The RMC60MMST is the direct functional equivalent for the obsolete AMC60MMST. Selection of the RMC60MMST is based on the following engineering factors:

Product Status: The RMC60MMST maintains active production status with confirmed inventory availability (1164 pcs), whereas the AMC60MMST is obsolete. This ensures long-term component supply for ongoing production and field service requirements.

Regulatory Compliance: Both connectors maintain ROHS3 compliance and MSL 1 classification, meeting current environmental and moisture sensitivity standards. The RMC60MMST carries ECCN EAR99 classification with HTSUS code 8536.69.4040, confirming export compliance status.

Electrical and Mechanical Compatibility: The RMC60MMST preserves all critical interface parameters including 120-position configuration, 0.100" pitch, dual read-out, gold contact finish at specified thickness, and identical operating temperature range. The connector maintains the same flange geometry and mounting configuration.

Contact Material Difference: The RMC60MMST employs phosphor bronze contacts in place of beryllium copper. Both materials provide equivalent electrical performance and durability in card edge connector applications at the specified contact finish thickness and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the RMC60MMST directly replace the AMC60MMST in existing designs?

A: Yes. The RMC60MMST maintains identical electrical and mechanical interface specifications including position count, pitch, gender, read-out configuration, contact finish, and flange geometry. Both connectors interface with the same female edgecard designs.

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

A: Both materials provide equivalent electrical conductivity and mechanical durability in card edge connector applications. The contact finish (gold at 30.0µin) is the primary determinant of electrical performance and corrosion resistance. The base material difference does not affect functional interchangeability.

Q: Are there any temperature or environmental limitations when substituting the RMC60MMST?

A: No. Both connectors operate across the identical temperature range of -65°C to 200°C. Both maintain MSL 1 classification and ROHS3 compliance, indicating equivalent environmental performance.

Q: What does the card thickness specification difference indicate?

A: The RMC60MMST specifies a card thickness of 0.062" (1.57mm), whereas the AMC60MMST does not include this specification. This parameter indicates the connector is designed for standard 0.062" edgecard thickness. This is a standard specification for 0.100" pitch card edge connectors and does not restrict compatibility.

Q: Are there any mounting or installation differences?

A: Both connectors feature identical flange geometry (flush mount, top opening, threaded insert, 4-40) and solder termination. Installation procedures and PCB layout requirements remain unchanged.

Q: What is the inventory status for the RMC60MMST?

A: The RMC60MMST is in active production with 1164 pcs confirmed in stock, ensuring availability for immediate procurement and future supply continuity.
