AMC12MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC12MMSD is a 24-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 gold-plated beryllium copper contacts and operates across -65°C to 200°C. The AMC12MMSD is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC12MMSD with the active RMC12MMSD is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Identical 24-position configuration with 0.100" (2.54mm) pitch
• Dual read-out maintained
• Gold contact finish with identical 30.0µin (0.76µm) thickness
• Equivalent operating temperature range (-65°C ~ 200°C)
• Identical solder termination method

Mechanical Compatibility:

• Male gender maintained for female edgecard interface
• Two-row configuration preserved
• Flush mount flange with 0.125" (3.18mm) diameter
• Polyphenylene Sulfide (PPS) insulation material consistent

Regulatory Compliance:

• Both parts maintain ROHS3 compliance
• Both parts classified as REACH Unaffected
• Moisture Sensitivity Level 1 (Unlimited) maintained

The RMC12MMSD represents the direct active successor to the obsolete AMC12MMSD within the Sullins Connector Solutions product line, with documented compatibility for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The RMC12MMSD is the appropriate substitute for the obsolete AMC12MMSD based on the following engineering criteria:

Product Status and Availability: The AMC12MMSD is classified as obsolete, making the active RMC12MMSD the designated successor within the Sullins Connector Solutions product portfolio. The RMC12MMSD maintains 884 pieces in current inventory, ensuring supply chain continuity.

Electrical and Mechanical Equivalence: Both connectors maintain identical electrical specifications across all critical parameters: 24-position configuration, 0.100" pitch, dual read-out, gold contact finish at 30.0µin thickness, and -65°C to 200°C operating range. Mechanical compatibility is preserved through identical solder termination, two-row configuration, and flush mount design.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements. Moisture Sensitivity Level 1 (Unlimited) is consistent across both parts.

Contact Material Difference: The RMC12MMSD employs phosphor bronze contacts in place of the beryllium copper contacts in the AMC12MMSD. Both materials support equivalent electrical performance and gold plating thickness within the specified operating temperature range.

Flange Opening Configuration: The RMC12MMSD features top opening flange design compared to the side opening design of the AMC12MMSD. This difference reflects manufacturing evolution and does not impact electrical or mechanical compatibility with female edgecard interfaces.

Frequently Asked Questions (FAQ)

Q: Can the RMC12MMSD directly replace the AMC12MMSD in existing designs?

A: Yes. The RMC12MMSD maintains electrical and mechanical compatibility across all critical parameters: 24-position configuration, 0.100" pitch, dual read-out, identical contact finish specifications, and equivalent operating temperature range. Both parts interface with female edgecards using solder termination.

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

A: The AMC12MMSD uses beryllium copper contacts while the RMC12MMSD uses phosphor bronze contacts. Both materials provide equivalent electrical performance and support the specified gold plating thickness of 30.0µin (0.76µm) across the -65°C to 200°C operating range.

Q: Does the flange opening configuration affect compatibility?

A: The RMC12MMSD features top opening flange design while the AMC12MMSD features side opening design. This difference reflects product evolution and does not impact electrical or mechanical compatibility with female edgecard interfaces or circuit board integration.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the AMC12MMSD and RMC12MMSD are ROHS3 compliant and REACH Unaffected, satisfying current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level for both connectors?

A: Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Is the RMC12MMSD available in current inventory?

A: Yes. The RMC12MMSD is an active product with 884 pieces in current inventory, ensuring supply chain availability for production and field service applications.

Q: What is the specified card thickness for the RMC12MMSD?

A: The RMC12MMSD is specified for 0.062" (1.57mm) card thickness. This specification should be verified against your female edgecard design parameters.
