Substitute Part Grouping Explanation

Substitute parts for the Molex 0743201304 are categorized based on strict electrical and mechanical parameter alignment:

Parametric Equivalents (Full Compatibility): Parts sharing identical connector type (DVI-I, Dual Link), contact count (29 positions), gender (Receptacle), mounting configuration (Panel Mount, Through Hole, Right Angle), electrical ratings (3A per contact, 40VAC), shielding (Shielded), and termination method (Solder). These parts differ only in packaging format or minor cosmetic features such as insulation color or mounting features (Board Guide vs. Board Lock).

Manufacturer Recommended Equivalent (Functional Compatibility with Parameter Variance): The Amphenol CONEC 33DVIR-24S1B shares the connector type (DVI-I, Dual Link), gender (Receptacle), mounting orientation (Through Hole, Right Angle), and termination (Solder). However, this part operates with reduced contact count (24 vs. 29 positions), lower current rating (1.5A vs. 3A per contact), higher voltage rating (250VAC vs. 40VAC), unshielded design, and extended operating temperature range (-55°C ~ 85°C vs. -20°C ~ 85°C). This part is suitable only when the application can accommodate the reduced pin count and lower current capacity.

Engineering Selection Recommendations

For Direct Replacement (Obsolete to Active): The Molex parts 0743209010, 0743201000, 0743201003, 0743201004, and 0743201007 are parametric equivalents of the 0743201304. All five parts maintain identical electrical specifications (3A per contact, 40VAC), mechanical configuration (29-position DVI-I Dual Link Receptacle, Panel Mount, Through Hole, Right Angle), shielding characteristics, and operating temperature range. All are Active status products with ROHS3 compliance and REACH Unaffected designation. These parts are suitable for direct substitution in applications currently using the 0743201304.

For Functional Compatibility with Design Verification: The Amphenol CONEC 33DVIR-24S1B may be considered only when the application design can accommodate a 24-position connector instead of 29 positions, accept reduced current capacity (1.5A per contact vs. 3A), and operate with an unshielded connector. This part offers extended temperature range capability (-55°C ~ 85°C) and higher voltage rating (250VAC). Design review and electrical validation are required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0743201304 be directly replaced with any of the listed Molex substitutes?

A: Yes. The Molex parts 0743209010, 0743201000, 0743201003, 0743201004, and 0743201007 are parametric equivalents with identical electrical and mechanical specifications. All maintain 29-position DVI-I Dual Link Receptacle configuration, 3A per contact current rating, 40VAC voltage rating, shielded design, and -20°C ~ 85°C operating temperature. These parts are direct substitutes suitable for PCB assembly without design modification.

Q: What is the primary difference between the Molex substitute parts?

A: The five Molex substitute parts differ in packaging format (Tray) and minor cosmetic features such as insulation color (Natural vs. White) and mounting feature designation (Board Guide vs. Board Lock). Electrical and mechanical performance characteristics are identical.

Q: Is the Amphenol CONEC 33DVIR-24S1B a suitable replacement?

A: The 33DVIR-24S1B shares the DVI-I Dual Link Receptacle connector type and right-angle through-hole mounting orientation. However, it operates with 24 positions instead of 29, reduced current capacity (1.5A vs. 3A per contact), unshielded design, and higher voltage rating (250VAC vs. 40VAC). This part is suitable only if the application design can accommodate these parameter differences. Electrical validation is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including the Molex equivalents and the Amphenol CONEC alternative, are ROHS3 Compliant and REACH Unaffected. All meet current environmental and regulatory requirements.

Q: What inventory availability should be considered?

A: The Molex 0743201004 offers the highest inventory level at 6938 pieces. The Molex 0743201000 provides 4613 pieces, and 0743201003 offers 3526 pieces. The Molex 0743209010 and 0743201007 provide 2542 and 2388 pieces respectively. The Amphenol CONEC 33DVIR-24S1B has 669 pieces available.
