Molex 0850033134 DIN Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0850033134 is a 64-position DIN connector header with male pins, gold-plated contacts, and right-angle through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The connector operates across the industrial temperature range of -55°C to 125°C and complies with RoHS3 and REACH regulations.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0850033134 are selected based on the following critical parameters that determine functional compatibility:

Pitch (0.100" / 2.54mm): All substitutes maintain identical pitch spacing for PCB footprint compatibility
Number of Rows (3): All substitutes retain the three-row configuration
Style (C): All substitutes conform to DIN 41612 Style C specification
Mounting Type (Through Hole, Right Angle): All substitutes use identical mounting orientation and method
Termination (Solder): All substitutes use solder termination for PCB assembly
Material Flammability Rating (UL94 V-0): All substitutes meet the same flammability standard
RoHS3 Compliance: All substitutes maintain regulatory compliance

The substitute parts are HARTING DIN 41612 connectors with 96-position capacity but loaded for 64 positions, providing direct functional equivalence to the original Molex component. These parts are active products with current manufacturing status and established supply availability.

Engineering Selection Recommendations

All three HARTING substitute parts (09031646921, 09033642921, 09033647921) provide direct functional equivalence to the obsolete Molex 0850033134 based on matching electrical and mechanical parameters. Selection among these substitutes depends on application-specific requirements:

HARTING 09031646921: Suitable for applications where operating temperature specification is not critical or where the application operates within standard industrial ranges. This part maintains Level/Class 2 designation consistent with the original Molex component.

HARTING 09033642921: Recommended for applications requiring documented operating temperature range (-55°C ~ 125°C) and current rating specification (2A). This part includes board lock feature and operates at Level/Class 1.

HARTING 09033647921: Recommended for applications requiring the highest level of contact reliability (Level/Class 3) with board lock feature, documented operating temperature range (-55°C ~ 125°C), and current rating specification (2A).

All substitute parts maintain RoHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory compliance for existing and new designs.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09031646921, 09033642921, and 09033647921 be used interchangeably with Molex 0850033134?

A: Yes, all three HARTING parts provide functional equivalence based on matching pitch (0.100"), number of loaded positions (64), number of rows (3), Style C configuration, through-hole right-angle mounting, and solder termination. PCB footprints are compatible.

Q: What is the difference between the three HARTING substitute parts?

A: The primary differences are Level/Class designation (2, 1, and 3 respectively), presence of board lock feature (09033642921 and 09033647921 only), and documented operating temperature and current rating specifications (09033642921 and 09033647921 only).

Q: Why do the HARTING parts have 96 positions when the Molex part has 64 positions?

A: The HARTING connectors are 96-position headers with 64 positions loaded. The loaded position count matches the original Molex component, providing identical functional capacity. The additional unloaded positions do not affect compatibility or performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all three HARTING substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of the original Molex component.

Q: What is the difference between Level/Class 1, 2, and 3?

A: Level/Class designation indicates contact reliability and mechanical robustness. Class 3 provides the highest level of contact reliability, followed by Class 2, then Class 1. Selection depends on application requirements for contact durability and signal integrity.
