AMC07MMST Equivalent & Substitute Parts

Part Overview

The AMC07MMST is a 14-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 with existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC07MMST with the active RMC07MMST is based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• 14-position connector configuration
• 0.100" (2.54mm) pitch spacing
• Male gender with dual read-out
• 2-row arrangement
• Gold contact finish at 30.0µin thickness
• Operating temperature range -65°C ~ 200°C
• Solder termination
• Polyphenylene Sulfide insulation material
• Flush mount with top opening and 4-40 threaded insert
• ROHS3 compliance
• MSL 1 rating

Allowable Variations:

• Contact material: Beryllium copper (AMC07MMST) to phosphor bronze (RMC07MMST)
• Card thickness specification: Not specified (AMC07MMST) to 0.062" (1.57mm) (RMC07MMST)
• Mounting type: Not specified (AMC07MMST) to through hole (RMC07MMST)
• Color: Not specified (AMC07MMST) to black (RMC07MMST)
• Product status: Obsolete to active

Parameter Comparison

Engineering Selection Recommendations

The RMC07MMST serves as the direct active equivalent for the obsolete AMC07MMST. Both connectors maintain identical electrical and mechanical specifications across all critical interface parameters: 14-position configuration, 0.100" pitch, dual read-out, gold contact finish, and operating temperature range.

The RMC07MMST is ROHS3 compliant and carries active product status with current manufacturing support. The phosphor bronze contact material in the RMC07MMST provides equivalent electrical performance to the beryllium copper contacts in the AMC07MMST, with both materials meeting the specified gold plating thickness and finish requirements.

The specified card thickness of 0.062" (1.57mm) for the RMC07MMST and through-hole mounting type represent standard design parameters for this connector class and do not restrict compatibility with existing female edgecard interfaces designed for 0.100" pitch male connectors.

Frequently Asked Questions (FAQ)

Q: Can the RMC07MMST directly replace the AMC07MMST in existing applications?

A: Yes. The RMC07MMST maintains identical pitch, position count, row configuration, contact finish, operating temperature range, and flange geometry. Both connectors interface with female edgecards at 0.100" spacing and provide dual read-out functionality.

Q: What is the difference between beryllium copper and phosphor bronze contacts?

A: Both materials are standard contact materials for gold-plated connectors. The phosphor bronze contacts in the RMC07MMST provide equivalent electrical conductivity and contact resistance characteristics when finished with the same 30.0µin gold plating thickness specified for both parts.

Q: Does the RMC07MMST card thickness specification of 0.062" affect compatibility?

A: No. The 0.062" (1.57mm) specification indicates the designed card thickness for optimal contact engagement. This is a standard thickness for edgecard applications and does not restrict the connector's ability to interface with female edgecards designed for 0.100" pitch male connectors.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant with MSL 1 rating. The RMC07MMST carries ECCN EAR99 classification and HTSUS code 8536.69.4040, indicating active product status with established regulatory documentation.

Q: What is the significance of the black color in the RMC07MMST?

A: The black color is a cosmetic specification of the polyphenylene sulfide insulation material and does not affect electrical or mechanical performance. The connector maintains all functional specifications regardless of color designation.
