Equivalent & Substitute Parts for Molex 0850426244

Part Overview

The Molex 0850426244 is a 96-position DIN receptacle connector with female sockets, gold plating, and through-hole termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The connector features a 0.100" (2.54mm) pitch, three-row configuration (Style C), and is rated for operating temperatures from -55°C to 125°C. Given its obsolete status, active equivalent models from HARTING provide direct functional alternatives while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0850426244 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 96
• Number of Positions Loaded: 64
• Pitch: 0.100" (2.54mm)
• Number of Rows: 3
• Style: C
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

Acceptable Variations:

• Contact Finish: Gold or Gold-Palladium finishes are functionally equivalent
• Insulation Material: Both Polyester Thermoplastic and Polybutylene Terephthalate (PBT) Glass Filled meet UL94 V-0 requirements
• Level/Class: Variations in Level/Class do not affect mechanical or electrical compatibility for this application
• Current Rating: Substitute parts rated at 2A exceed the requirements of the original part

The three HARTING DIN 41612 series connectors listed below meet all primary matching criteria and are classified as active products, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09032642825 is the primary substitute for the Molex 0850426244. This connector matches all critical parameters: 96 positions, 64 positions loaded, three-row Style C configuration, 0.100" pitch, through-hole solder termination, and -55°C to 125°C operating range. The contact finish is specified as Gold or Gold-Palladium, providing equivalent electrical performance to the original gold-plated design. The part is active and ROHS3 compliant with UL94 V-0 flammability rating.

HARTING 09034646824 provides an alternative with identical position count, row configuration, and pitch specifications. This variant features Gold-Palladium contact finish and includes mounting clips as an additional feature. It maintains full compliance with RoHS3 and UL94 V-0 standards. The Level/Class rating of 2 differs from the original part's Level/Class 3, but this does not affect mechanical or electrical compatibility.

HARTING 09027646824 is a reduced-position alternative with 64 total positions in a two-row Style B configuration. This part is suitable only for applications where the reduced position count and two-row layout are compatible with the existing PCB design and mating connector. It shares the same pitch, termination method, operating temperature range, and compliance certifications as the original part.

All three substitute parts are manufactured by HARTING, classified as active products, and maintain ROHS3 compliance and UL94 V-0 flammability certification. Selection should be based on PCB layout compatibility and position requirements.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09032642825 be used as a direct replacement for Molex 0850426244?

A: Yes. The HARTING 09032642825 matches all critical electrical and mechanical parameters: 96-position receptacle, 64 positions loaded, three-row Style C configuration, 0.100" pitch, through-hole solder termination, and -55°C to 125°C operating temperature. The Gold or Gold-Palladium contact finish is functionally equivalent to the original gold plating. PCB footprint compatibility must be confirmed for your specific application.

Q: What is the difference between HARTING 09032642825 and HARTING 09034646824?

A: Both connectors share identical position count, row configuration, pitch, and termination specifications. The primary difference is the contact finish: 09032642825 offers Gold or Gold-Palladium, while 09034646824 specifies Gold-Palladium. Additionally, 09034646824 includes mounting clips as a feature. Both are active products with equivalent compliance certifications.

Q: Why is HARTING 09027646824 listed as a substitute if it has only 64 positions?

A: The HARTING 09027646824 is a reduced-position alternative suitable only for applications where the PCB design accommodates a two-row Style B configuration instead of the three-row Style C layout. It maintains compatibility in pitch, termination, operating temperature, and compliance standards but requires different PCB footprint design. This part is not a direct replacement for all applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three HARTING substitute parts are ROHS3 compliant and carry UL94 V-0 flammability certification, matching the compliance profile of the original Molex 0850426244.

Q: What is the significance of the Level/Class rating difference?

A: The original Molex part is rated Level/Class 3, while the HARTING substitutes are rated Level/Class 1 or 2. These ratings relate to connector design standards but do not affect mechanical fit, electrical performance, or compatibility with standard DIN 41612 mating connectors for this application category.

Q: Can the insulation material difference affect performance?

A: Both Polyester Thermoplastic (original) and Polybutylene Terephthalate (PBT) Glass Filled (substitutes) meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range of -55°C to 125°C. The material change does not affect electrical or mechanical compatibility.
