Key Parameters

Substitute Part Grouping Explanation

Substitution of the DML-1-04-V-T-SMT is determined by strict alignment of the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Position count (4 positions) and mating pitch (3.00mm)
• Mounting technology (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)
• Contact material and finish (Brass with Tin plating)
• Electrical ratings (5A current, 250VAC/DC voltage)
• Flammability compliance (UL94 V-0)
• RoHS3 compliance status

The Molex 0436500424 (Micro-Fit 3.0 series) meets all these critical parameters and qualifies as a direct substitute for the obsolete DML-1-04-V-T-SMT.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0436500424 is a qualified substitute for the obsolete DML-1-04-V-T-SMT based on the following factors:

Product Status Alignment: The DML-1-04-V-T-SMT is obsolete, while the Molex 0436500424 maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance Equivalence: Both components maintain ROHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications, satisfying regulatory requirements for equivalent substitution.

Electrical and Mechanical Compatibility: The substitute part matches all critical electrical parameters (5A current rating, 250VAC/DC voltage rating) and mechanical specifications (4-position, 3.00mm pitch, surface mount, shrouded 4-wall configuration with locking ramp fastening).

Material and Finish Specifications: Identical brass contact material with tin plating on both mating and post surfaces ensures equivalent electrical performance and solder joint reliability.

Thermal and Environmental Ratings: Both components operate across the -40°C to 105°C temperature range with UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0436500424 be used as a direct replacement for the DML-1-04-V-T-SMT?

A: Yes. The Molex 0436500424 meets all critical electrical, mechanical, and compliance parameters specified for the DML-1-04-V-T-SMT. Both components share identical pitch (3.00mm), position count (4), shrouding configuration (4-wall), fastening type (locking ramp), and electrical ratings (5A, 250VAC/DC).

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity and product status. The DML-1-04-V-T-SMT is obsolete, while the Molex 0436500424 is in active production. The Molex part uses Liquid Crystal Polymer (LCP) glass-filled insulation material compared to the thermoplastic insulation of the Adam Tech part. The Molex part also specifies additional parameters including insulation height (0.390"), contact finish thickness (100.0µin), and mated stacking height (17.56mm).

Q: Are there packaging differences between these parts?

A: Yes. The DML-1-04-V-T-SMT packaging is not specified in available documentation. The Molex 0436500424 is available in Cut Tape (CT) and Digi-Reel packaging options, as well as standard Tape & Reel (TR) format, providing flexibility for different procurement and assembly workflows.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DML-1-04-V-T-SMT and Molex 0436500424 are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the current availability status of each part?

A: The DML-1-04-V-T-SMT is obsolete with 628 pieces reported in new original stock. The Molex 0436500424 is in active production with 23,425 pieces available in new original stock, providing superior long-term supply assurance.
