Molex 0850400127 64-Position DIN Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0850400127 is a 64-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 is designed for backplane applications requiring reliable signal and power distribution across dual-row configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0850400127 is determined by the following critical parameters:

• Connector Configuration: 64 positions, receptacle type with female sockets
• Pitch and Spacing: 0.100" (2.54mm) pitch maintained across all substitutes
• Mounting and Termination: Through-hole solder termination required
• Electrical Performance: Operating temperature range -55°C to 125°C
• Compliance: UL94 V-0 flammability rating and RoHS3 compliance
• Contact Material: Gold or gold-palladium plating acceptable

Two active substitute parts meet these criteria and are available in production inventory.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09022642825 is the manufacturer-recommended primary substitute. This part maintains full electrical and mechanical compatibility with the original Molex 0850400127, with the exception of a single-row configuration versus the dual-row layout. The HARTING connector carries active product status with ROHS3 compliance and is currently in production inventory (1041 units available). The gold-palladium contact finish provides equivalent performance to the original gold plating.

Amphenol ICC 86092646114755V1LF serves as a secondary substitute option. This part preserves the dual-row configuration of the original Molex connector and maintains identical pitch, position count, and mounting specifications. The Amphenol ICC connector is active in production with RoHS compliance certification and 1132 units in current inventory. The gold contact finish matches the original specification.

Both substitutes satisfy all mandatory compliance requirements including UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1). Selection between the two substitutes depends on specific PCB layout requirements, with the HARTING option suitable for single-row applications and the Amphenol ICC option preferred when dual-row footprint compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09022642825 be used as a direct replacement for the Molex 0850400127?

A: The HARTING connector is electrically and mechanically compatible for all 64 positions at 0.100" pitch with identical solder termination. The primary difference is the single-row versus dual-row configuration. PCB layout must accommodate this structural change.

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

A: Both finishes provide equivalent electrical performance and corrosion resistance for this connector category. Gold-palladium plating (HARTING) offers enhanced durability in high-cycle mating applications. Gold plating (Amphenol ICC) matches the original Molex specification.

Q: Are both substitute parts RoHS compliant?

A: Yes. The HARTING 09022642825 carries ROHS3 certification. The Amphenol ICC 86092646114755V1LF carries RoHS compliance certification. Both meet regulatory requirements for restricted substance elimination.

Q: What is the current availability of these substitute parts?

A: HARTING 09022642825 has 1041 units in stock. Amphenol ICC 86092646114755V1LF has 1132 units in stock. Both are active production parts with ongoing availability.

Q: Does the operating temperature range remain the same across all three connectors?

A: Yes. The Molex original, HARTING substitute, and Amphenol ICC substitute all operate across the -55°C to 125°C temperature range with identical thermal performance specifications.

Q: What packaging format is available for each substitute?

A: HARTING 09022642825 is supplied in bulk packaging. Amphenol ICC 86092646114755V1LF is supplied in tray packaging. Packaging selection may affect handling and storage procedures in manufacturing environments.
