Molex 0850010050 DIN Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0850010050 is a 64-position DIN connector header with male pins, gold plating, and right-angle through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new production runs. The part operates across the industrial temperature range of -55°C to 125°C and complies with RoHS3 and UL94 V-0 flammability standards.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0850010050 is determined by the following critical parameters:

Connector Type & Configuration: Header, male pins with 64 positions, 32 positions loaded, 2-row arrangement, Style B
Physical Interface: 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination
Environmental & Compliance: Operating temperature range -55°C to 125°C, UL94 V-0 flammability rating, RoHS3 compliance, MSL 1 (unlimited moisture sensitivity)
Contact System: Gold or gold-palladium plating acceptable for electrical equivalence

The HARTING DIN 41612 series parts listed below meet these core substitution criteria. Variations in contact finish thickness, insulation material composition, and current rating specifications do not preclude functional equivalence when the primary parameters align.

Engineering Selection Recommendations

Primary Substitutes for 64-Position Configuration:

HARTING 09021322931, 09021327921, and 09021327931 are direct functional equivalents to the Molex 0850010050. All three maintain the 64-position, 32-loaded configuration with identical pitch, row count, style, and mounting orientation. All substitute parts are active products with current manufacturing support, RoHS3 compliance, and UL94 V-0 certification. The HARTING DIN 41612 series provides superior long-term availability compared to the obsolete Molex part.

Contact finish variations (gold versus gold-palladium) do not affect electrical performance in standard backplane connector applications. The 2A current rating specified for HARTING parts exceeds typical requirements for this connector class.

Alternative for Reduced Position Count:

HARTING 09021326931 provides a 32-position, 16-loaded configuration. This part is suitable only for applications where the reduced position count meets functional requirements. It maintains all other critical parameters including pitch, mounting type, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09021322931 directly replace the Molex 0850010050 in existing PCB designs?

A: Yes. Both parts share identical pitch (0.100"), position count (64 total, 32 loaded), row configuration (2), style (B), and mounting type (through-hole right-angle). PCB footprints are compatible without modification.

Q: What is the difference between gold and gold-palladium contact finishes?

A: Both finishes provide equivalent electrical performance in standard backplane applications. Gold-palladium offers enhanced wear resistance in high-cycle mating environments. Selection depends on application-specific durability requirements, not electrical compatibility.

Q: Why is HARTING 09021326931 listed as a substitute if it has only 32 positions?

A: HARTING 09021326931 is functionally equivalent only for applications using 32 positions or fewer. It maintains all other critical parameters but cannot accommodate designs requiring the full 64-position capacity of the original part.

Q: Are all listed HARTING parts RoHS3 compliant?

A: Yes. All HARTING substitute parts (09021322931, 09021327921, 09021327931, 09021326931) are RoHS3 compliant and carry UL94 V-0 flammability certification, matching the compliance profile of the Molex 0850010050.

Q: What is the operating temperature range for HARTING 09021326931?

A: Operating temperature is not specified in the available technical data for this part. For applications requiring confirmed -55°C to 125°C operation, use HARTING 09021322931, 09021327921, or 09021327931.
