242A10120X D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 242A10120X is a 37-position D-Sub receptacle connector with female sockets, designed for through-hole solder termination. This component features a 2-row configuration (Shell Size 4, DC layout) with gold-plated copper alloy contacts and a tin-plated steel housing.

The 242A10120X is classified as an obsolete product. Identifying equivalent and substitute parts ensures continued availability for legacy system support, maintenance, and production sustainability. The obsolete status necessitates sourcing alternative components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Electrical and mechanical substitution for the 242A10120X is determined by the following critical parameters:

Electrical Compatibility Requirements:

• 37-position connector configuration
• Current rating minimum 7.5A
• Voltage rating minimum 100V
• Operating temperature range -25°C to 105°C or greater

Mechanical Compatibility Requirements:

• D-Sub receptacle type with female sockets
• Shell Size 4 (DC, C layout)
• Through-hole mounting capability
• Solder termination compatibility

Material and Environmental Requirements:

• Gold-plated contact finish (8.00µin minimum thickness)
• RoHS3 compliance for modern supply chains
• Ingress protection rating IP20 or equivalent

The substitute part 24-003113 maintains all critical electrical parameters (37-position, receptacle female type, Shell Size 4 configuration) and termination methodology while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The Amphenol CONEC 24-003113 is the appropriate substitute for the obsolete 242A10120X. Both components are manufactured by Amphenol CONEC and share identical electrical and mechanical specifications for the critical substitution parameters: 37-position configuration, receptacle female type, Shell Size 4 (DC, C), and solder termination.

The 24-003113 offers the significant advantage of active product status, ensuring long-term availability and continued support from the manufacturer. This eliminates supply chain risk associated with obsolete components and provides access to current manufacturing processes and quality assurance protocols.

Both components maintain RoHS compliance and are suitable for applications requiring 7.5A current capacity at 100V voltage rating across the operating temperature range of -25°C to 105°C.

Frequently Asked Questions (FAQ)

Q: What determines if a D-Sub connector can substitute for the 242A10120X?

A: Substitution requires matching the following critical parameters: 37-position configuration, receptacle type with female sockets, Shell Size 4 (DC, C) layout, through-hole mounting, and solder termination capability. The connector must support minimum 7.5A current and 100V voltage rating across -25°C to 105°C.

Q: Is the 24-003113 fully compatible with designs using 242A10120X?

A: Yes. The 24-003113 matches all critical electrical and mechanical parameters specified for the 242A10120X, including position count, connector type, shell size, mounting style, and termination method. Both components are manufactured by the same supplier under equivalent specifications.

Q: Why is the 242A10120X marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. However, existing inventory remains available. The active-status 24-003113 provides a forward-compatible solution for new designs and ongoing production requirements.

Q: What is the significance of Shell Size 4 (DC, C)?

A: Shell Size 4 defines the physical envelope and contact pitch of the D-Sub connector. This specification ensures mechanical fit within standard D-Sub backshells and mating connectors. Substitutes must maintain this specification to ensure proper assembly and interconnection.

Q: Are there differences in contact finish specifications between these parts?

A: Contact finish specifications are not provided for the substitute part 24-003113. Verify contact material and plating thickness with the manufacturer or technical datasheet to confirm compatibility with the main part's gold plating (8.00µin) if contact finish is critical to the application.
