242A12840X D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 242A12840X is a 25-position D-Sub receptacle connector with right-angle solder termination, designed for signal applications requiring board-level interconnection. This connector is classified as obsolete, necessitating identification of active substitute models to maintain design continuity and ensure procurement availability. The 242A12840X remains available in inventory (639 units) but sourcing new production units may be constrained due to its obsolete status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub receptacle connectors is determined by the following critical parameters:

Functional Equivalence Parameters:

• Connector type (receptacle with female sockets)
• Number of positions (25)
• Shell size and layout (Size 3, DB configuration)
• Mounting style (through-hole, right-angle orientation)
• Termination method (solder)

Environmental & Electrical Compatibility Parameters:

• Voltage rating (minimum 100V)
• Current rating (minimum 7.5A)
• Operating temperature range (-25°C to +105°C)
• Contact finish properties (gold plating for signal integrity)

Compliance & Material Parameters:

• RoHS3 compliance requirement
• Flammability rating (UL94 V-0)
• Shell material compatibility (steel construction)

The Amphenol CONEC 24-003313 qualifies as a direct substitute based on matching all functional parameters: 25-position D-Sub receptacle with right-angle solder termination and active product status, ensuring long-term procurement availability.

Engineering Selection Recommendations

For New Designs and Long-Term Deployment:

Select the Amphenol CONEC 24-003313 (active product status) for all new design implementations and ongoing procurement. This part is manufacturer-recommended as a direct substitute and maintains active production status, ensuring stable supply chain availability and consistent manufacturing processes.

For Existing Stock Management:

The 242A12840X may continue to be used in manufacturing and service operations while inventory remains available (639 units in stock). Transition timelines should account for the 1154-unit inventory of the 24-003313 substitute, enabling smooth migration without supply chain disruptions.

Compliance Assurance:

Both parts are supplied by Amphenol CONEC and maintain appropriate certifications for D-Sub connector applications. Confirm specific compliance documentation (RoHS3, REACH, flammability) for the 24-003313 through current manufacturer datasheets prior to final design lock.

Frequently Asked Questions (FAQ)

Q: Can the 24-003313 directly replace the 242A12840X in existing PCB designs?

A: The 24-003313 is the manufacturer-recommended substitute for the 242A12840X, both being 25-position D-Sub receptacles with solder termination and right-angle mounting. Mechanical fit and electrical performance are equivalent, supporting direct PCB design reuse.

Q: What is the primary reason for substitution?

A: The 242A12840X is classified as obsolete, creating long-term procurement risk. The 24-003313 maintains active product status with higher current inventory (1154 units vs. 639 units), providing supply security for ongoing production.

Q: Are there dimensional or packaging differences between these parts?

A: Both connectors share the same functional configuration (25-position D-Sub receptacle, right-angle solder). Dimensional compatibility is expected based on the standard D-Sub Size 3 footprint. Confirm mechanical drawings from the manufacturer for pin-to-pin and mounting hole specifications.

Q: What certifications apply to the 24-003313?

A: Specific certification details for the 24-003313 are not provided in this reference. Consult the current Amphenol CONEC datasheet to verify RoHS3, REACH, UL94 flammability, and other compliance status applicable to your application requirements.

Q: Is the 24-003313 suitable for the same electrical ratings (100V, 7.5A)?

A: The 24-003313 is a 25-position D-Sub receptacle from Amphenol CONEC with solder termination, indicating electrical compatibility with standard D-Sub specifications. Confirm voltage and current ratings in the official datasheet before final integration.
