Molex 0423770962 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0423770962 is a through-hole, right-angle rectangular connector header with 36 positions at 0.100" (2.54mm) pitch. This connector is designed for board-to-board or cable applications in automotive, medical, telecommunications, and general-purpose electronics. The part is currently active in production with 979 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0423770962 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 36 positions at 0.100" (2.54mm) mating pitch
• Mounting & Orientation: Through-hole, right-angle mounting
• Termination Method: Solder termination
• Contact Finish: Gold-plated mating surface
• Shrouding: Unshrouded design
• Compliance: UL94 V-0 flammability rating and RoHS compliance

The Amphenol ICC (FCI) part number 68458-136HLF meets these substitution criteria. Both connectors share identical position count, pitch spacing, mounting orientation, and termination method. Both feature gold-plated mating contacts, unshrouded construction, and UL94 V-0 material flammability ratings. The substitute part operates across -65°C to 130°C and carries a 3A current rating, providing functional equivalence for the specified application categories.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0423770962 and Amphenol ICC 68458-136HLF connectors are active production parts with equivalent electrical and mechanical characteristics suitable for direct substitution in 36-position, 2.54mm pitch applications.

The Molex part carries ROHS3 compliance certification, while the Amphenol ICC substitute carries RoHS compliance. Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 (unlimited) moisture sensitivity ratings. The Amphenol ICC part provides documented operating temperature range (-65°C to 130°C) and current rating (3A), specifications not provided for the Molex original. The Amphenol ICC substitute features gold plating thickness of 30.0µin (0.76µm) on mating contacts, exceeding the Molex specification of 15.0µin (0.38µm), which provides enhanced durability and contact reliability.

Selection between these parts should be based on supply availability, cost considerations, and any design-specific requirements related to the documented operating temperature or current rating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 68458-136HLF directly replace the Molex 0423770962 in existing designs?

A: Yes. Both connectors share identical position count (36), mating pitch (0.100" / 2.54mm), mounting type (through-hole, right-angle), termination method (solder), and contact configuration (male pins, square shape, gold-plated mating surface). The mechanical and electrical interfaces are equivalent.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer and series designation. The Amphenol ICC part operates across a documented temperature range of -65°C to 130°C with a 3A current rating, specifications not provided for the Molex original. The Amphenol ICC part also features thicker gold plating on mating contacts (30.0µin versus 15.0µin), which enhances contact durability. Insulation height differs slightly (0.095" versus 0.098"), a negligible variance within standard manufacturing tolerances.

Q: Are there any compliance or certification differences?

A: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 (unlimited) moisture sensitivity ratings. The Molex part carries ROHS3 compliance, while the Amphenol ICC part carries RoHS compliance. Both are classified under ECCN EAR99 and HTSUS code 8536.69.4040.

Q: What is the contact finish difference, and does it affect compatibility?

A: The Molex part specifies gold mating contact finish at 15.0µin (0.38µm) thickness. The Amphenol ICC substitute specifies gold or gold GXT™ at 30.0µin (0.76µm) thickness. The thicker plating on the substitute part exceeds the original specification and does not compromise compatibility; it provides enhanced wear resistance and contact reliability.

Q: Are both parts available in the same packaging format?

A: Yes. Both the Molex 0423770962 and Amphenol ICC 68458-136HLF are supplied in bulk packaging, consistent with standard rectangular connector distribution methods.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability, cost, and any application-specific requirements. The Amphenol ICC part provides documented operating temperature and current rating specifications, which may be advantageous for designs requiring explicit thermal or power handling verification. Both parts are suitable for automotive, medical, telecommunications, and general-purpose applications.
