AMC22MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC22MMSD is a 44-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 AMC22MMSD 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.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC22MMSD with the active RMC22MMSD is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Identical position count (44 positions)
• Identical pitch specification (0.100" / 2.54mm)
• Identical gender configuration (Male)
• Identical row configuration (2 rows)
• Identical read-out type (Dual)
• Identical termination method (Solder)
• Identical contact finish (Gold at 30.0µin thickness)
• Identical operating temperature range (-65°C ~ 200°C)

Mechanical Compatibility:

• Identical insulation material (Polyphenylene Sulfide)
• Identical flange diameter specification (0.125" / 3.18mm)
• Identical flush mount configuration

Compliance Compatibility:

• Both ROHS3 Compliant
• Both MSL 1 (Unlimited)
• Both REACH Unaffected

Differences Noted: The RMC22MMSD introduces the following variations: phosphor bronze contact material (versus beryllium copper), specified card thickness of 0.062" (1.57mm), top opening flange (versus side opening), black color designation, and through-hole mounting type specification. These differences do not preclude functional substitution within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The RMC22MMSD serves as the direct active equivalent for the obsolete AMC22MMSD. Both connectors maintain identical electrical specifications across position count, pitch, gender, row configuration, and operating temperature range. Both achieve ROHS3 compliance and unlimited moisture sensitivity classification, satisfying regulatory requirements for current production and field applications.

The transition from AMC22MMSD to RMC22MMSD is supported by:

1. Product Status: RMC22MMSD is active with confirmed inventory availability (692 pcs), whereas AMC22MMSD is obsolete.

2. Regulatory Compliance: Both parts maintain equivalent ROHS3 and REACH compliance status, ensuring no regulatory barriers to substitution.

3. Electrical Equivalence: Identical contact finish thickness (30.0µin), operating temperature range (-65°C ~ 200°C), and dual read-out configuration ensure functional compatibility.

4. Mechanical Compatibility: Both employ PPS insulation material and identical flange specifications, supporting direct mechanical interchange in existing designs.

Selection of RMC22MMSD eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for AMC22MMSD.

Frequently Asked Questions (FAQ)

Q: Can RMC22MMSD directly replace AMC22MMSD in existing designs?

A: Yes. Both connectors share identical electrical specifications: 44 positions, 0.100" pitch, male gender, dual read-out, solder termination, gold contact finish at 30.0µin thickness, and -65°C to 200°C operating range. Both employ PPS insulation and identical flange geometry. The RMC22MMSD is the active equivalent for the obsolete AMC22MMSD.

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

A: The AMC22MMSD uses beryllium copper contacts, while the RMC22MMSD uses phosphor bronze contacts. Both materials are suitable for card edge connector applications and maintain the specified gold plating thickness. The contact material difference does not affect electrical compatibility within the specified parameters.

Q: Does the RMC22MMSD specify a card thickness requirement?

A: Yes. The RMC22MMSD specifies a card thickness of 0.062" (1.57mm). The AMC22MMSD does not specify card thickness in the provided parameters. Verify that existing edgecard designs conform to this 0.062" thickness specification.

Q: What is the difference between side opening and top opening flange configurations?

A: The AMC22MMSD features a side opening flange, while the RMC22MMSD features a top opening flange. Both are flush mount configurations with identical 0.125" (3.18mm) diameter specifications. The flange opening orientation may affect card insertion direction and mechanical assembly procedures in existing designs.

Q: Are both connectors RoHS compliant?

A: Yes. Both AMC22MMSD and RMC22MMSD are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component procurement and use.

Q: What is the inventory status for these connectors?

A: AMC22MMSD has 697 pcs in stock but is classified as obsolete. RMC22MMSD has 692 pcs in stock and is classified as active, ensuring continued availability for new production and field service applications.
