Molex 0353010240 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0353010240 is a shrouded vertical header connector with 2 positions and 2.5mm pitch, designed for through-hole board-to-cable/wire applications. This connector features a detent lock fastening mechanism and tin-plated brass contacts. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support, maintenance, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0353010240 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch specification (0.098" / 2.50mm)
• Number of positions (2)
• Number of rows (1)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Detent Lock)
• Contact shape (Circular)
• Contact finish (Tin)
• Contact material (Brass)
• Flammability rating (UL94 V-0)
• Regulatory compliance (ROHS3, REACH Unaffected)

The Molex 0022035025 meets all these criteria and qualifies as a direct substitute. While the insulation material differs (PA66 Glass Filled vs. PA46), both materials satisfy the UL94 V-0 flammability requirement and are suitable for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022035025 is the qualified substitute for the obsolete Molex 0353010240. Both connectors maintain identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status with substantial inventory availability (34,294 pieces), ensuring supply chain continuity.

Both parts satisfy identical regulatory requirements: ROHS3 compliance, REACH unaffected status, UL94 V-0 flammability rating, and EAR99 export classification. The insulation material composition differs between the two parts (PA46 versus PA66 with glass fill), but both materials meet the same flammability and performance standards required for the specified applications in automotive, industrial, medical, and telecommunications sectors.

Selection of the 0022035025 substitute eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022035025 be used as a direct replacement for the 0353010240 in existing designs?

A: Yes. Both connectors share identical specifications for pitch (2.50mm), position count (2), contact type (male pin), shrouding configuration, mounting method (through hole), and termination type (solder). All mechanical and electrical parameters are equivalent.

Q: What is the primary difference between these two connector models?

A: The main difference is product status and insulation material composition. The 0353010240 is obsolete and uses PA46 nylon insulation, while the 0022035025 is active production and uses PA66 glass-filled nylon insulation. Both materials meet UL94 V-0 flammability requirements.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, REACH unaffected status, UL94 V-0 flammability rating, and EAR99 export classification. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both.

Q: What are the packaging considerations when sourcing the substitute part?

A: The 0353010240 was supplied in standard packaging, while the 0022035025 is supplied in bulk packaging. Bulk packaging does not affect connector functionality or performance; it only impacts order quantities and handling procedures.

Q: Are these connectors suitable for automotive applications?

A: Yes. Both the 0353010240 and 0022035025 are rated for automotive applications, along with general purpose, industrial, medical, and telecommunications use. The UL94 V-0 flammability rating and ROHS3 compliance support automotive qualification requirements.

Q: What is the contact finish specification for both connectors?

A: Both connectors feature tin-plated brass contacts. The mating contact finish is tin, and the post contact finish is also tin. Contact material is brass in both cases.
