Amphenol CONEC 243A12220X D-Sub Adapter Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 243A12220X is a D-Sub adapter connector that converts between a 25-pin male D-Sub connector and a 25-pin female D-Sub connector. This connector saver device is configured for free-hanging (in-line) mounting and includes integrated filtering. The 243A12220X is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol CONEC 243A12220X is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Connector type: D-Sub adapter (25-pin male to 25-pin female conversion)
• Connector style: Connector saver
• Mounting configuration: Free hanging (in-line)
• Integrated features: Filter

Electrical Parameters:

• Voltage rating: 100 V minimum
• Current rating: 7.5 A minimum
• Contact finish: Gold
• Pin count and row configuration: 25 pins, 2 rows

Mechanical Parameters:

• Shell material and finish: Steel with tin plating
• Ingress protection: IP20 or equivalent
• Operating temperature range: -25°C to 105°C or broader

Compliance Parameters:

• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected

Substitute parts must satisfy all parameters listed above. Parts that differ in connector gender configuration, pin count, mounting type, or compliance status are not equivalent and cannot be substituted.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol CONEC 24-012123 is identified as the manufacturer-recommended substitute for the obsolete 243A12220X. Both parts are manufactured by Amphenol CONEC and share identical functional descriptions as D-Sub adapters converting DB25M to DB25F configurations.

Product Status Consideration: The 243A12220X is classified as obsolete, while the 24-012123 is active. This status transition indicates that the 24-012123 represents the current production equivalent and is the appropriate selection for new designs and ongoing procurement requirements.

Compliance Basis: The main part 243A12220X carries ROHS3 compliance and REACH unaffected status. Substitute selection should maintain these compliance certifications to ensure regulatory continuity in applications subject to environmental and safety standards.

Inventory Availability: The 243A12220X maintains 755 pieces in current stock (new original condition). The 24-012123 maintains 815 pieces in current stock (new original condition), providing adequate supply for both immediate and sustained procurement needs.

Selection Criteria: For new system designs and long-term applications, the 24-012123 is the appropriate selection due to active product status and manufacturer recommendation. For legacy system maintenance where original part specifications are critical, the 243A12220X remains available from current inventory while stock is maintained.

Frequently Asked Questions (FAQ)

Q: What is the functional difference between the 243A12220X and the 24-012123?

A: Both parts are D-Sub adapter connectors that convert 25-pin male D-Sub connectors to 25-pin female D-Sub connectors. The primary difference is product status: the 243A12220X is obsolete, while the 24-012123 is active production. The 24-012123 is the manufacturer-recommended equivalent.

Q: Can the 24-012123 be used as a direct replacement for the 243A12220X in existing applications?

A: The 24-012123 is identified as the manufacturer-recommended substitute. Both parts share identical functional descriptions and are manufactured by Amphenol CONEC. Direct substitution is supported by the manufacturer recommendation.

Q: What are the critical parameters that determine substitution eligibility for D-Sub adapters?

A: Substitution eligibility is determined by: connector gender configuration (male-to-female conversion), pin count (25 pins), row configuration (2 rows), mounting type (free hanging in-line), connector style (connector saver), integrated features (filter), electrical ratings (voltage and current), shell material and finish, contact finish specifications, ingress protection rating, and compliance certifications (RoHS, REACH, UL94).

Q: Are there any compliance differences between the 243A12220X and the 24-012123?

A: The 243A12220X is documented as ROHS3 compliant and REACH unaffected. Compliance specifications for the 24-012123 are not provided in the available data. Compliance verification should be obtained from the manufacturer for the 24-012123 prior to use in regulated applications.

Q: What is the operating temperature range for these adapters?

A: The 243A12220X operates across -25°C to 105°C. Operating temperature specifications for the 24-012123 are not provided in the available data.

Q: Why is the 243A12220X classified as obsolete?

A: Obsolete classification indicates that the part is no longer in active production. The 24-012123 represents the current production equivalent and is the recommended selection for ongoing procurement.

Q: What does the connector saver designation mean?

A: Connector saver refers to the adapter's function in protecting primary connectors from repeated mating cycles. By using an adapter connector, the primary connector experiences reduced wear, extending its operational life.

Q: What is the significance of the filter feature in this adapter?

A: The integrated filter provides electromagnetic interference (EMI) suppression for the D-Sub connection, improving signal integrity in applications sensitive to electrical noise.
