Molex 0434590013 Equivalent & Substitute Parts

Part Overview

The Molex 0434590013 is a rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This connector features 24 positions arranged in 2 rows with a 0.165" (4.20mm) pitch, shrouded design with 4 walls, and push-pull fastening. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0434590013 is determined by the following critical parameters:

• Connector Configuration: 24 positions, 2 rows, 0.165" (4.20mm) pitch and row spacing
• Mounting and Termination: Through-hole solder termination
• Shrouding: 4-wall shrouded design
• Contact Specifications: Male pin, brass material, tin finish
• Insulation Material: Polyamide (PA66) or equivalent nylon composition
• Compliance: RoHS3 compliance and UL94 flammability rating

The identified substitute parts maintain these core electrical and mechanical parameters while offering active product status or improved availability. Variations in fastening type (push-pull versus latch holder) and minor differences in contact finish thickness do not prevent functional substitution in applications where the connector interface geometry and electrical characteristics remain constant.

Parameter Comparison

Engineering Selection Recommendations

Molex 0015246241: This part is the manufacturer-recommended substitute and maintains active product status. It shares identical electrical and mechanical specifications with the original part, including 24-position configuration, 4.20mm pitch, through-hole mounting, and shrouded design. The primary difference is the fastening mechanism (latch holder versus push-pull), which does not affect connector interface compatibility. Material flammability rating differs at UL94 V-2 versus the original V-0 rating. This part is suitable for applications where the fastening mechanism change is acceptable and flammability requirements do not mandate V-0 compliance.

TE Connectivity 2-1586587-4: This part maintains the same 24-position, 4.20mm pitch configuration and through-hole mounting. It features UL94 V-0 flammability rating matching the original specification. The part is discontinued at DiGi Electronics but remains available through alternative distribution channels. Contact finish thickness on the mating surface is reduced (39.4µin versus 100.0µin), and the connector style is specified as board-to-cable/wire rather than board-to-board. Operating temperature range (-40°C to 105°C) and electrical ratings (9A current, 600VAC voltage) are provided. This part is suitable for applications requiring V-0 flammability compliance and where the board-to-cable configuration is appropriate.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0015246241 directly replace the 0434590013 in existing designs?

A: The 0015246241 maintains identical connector geometry, pitch, position count, and mounting method. The fastening mechanism differs (latch holder versus push-pull), which affects mating force and retention characteristics but not the electrical interface. Designs must accommodate the different fastening behavior. Material flammability rating is UL94 V-2 instead of V-0; applications requiring V-0 compliance must evaluate this difference.

Q: What is the primary difference between the Molex and TE Connectivity options?

A: The Molex 0015246241 is the active manufacturer-recommended substitute with identical specifications except fastening type and flammability rating. The TE Connectivity 2-1586587-4 offers UL94 V-0 compliance matching the original part but is discontinued at DiGi Electronics. Contact finish thickness is thinner on the TE part (39.4µin versus 100.0µin), and the connector style is specified for board-to-cable applications rather than board-to-board.

Q: Are there packaging differences between these parts?

A: The Molex 0434590013 and 0015246241 are supplied in bulk packaging. The TE Connectivity 2-1586587-4 packaging specification is not provided in the available data.

Q: Do all three parts meet RoHS compliance?

A: Yes. The Molex 0434590013 and 0015246241 are ROHS3 compliant. The TE Connectivity 2-1586587-4 is RoHS compliant. All parts meet lead-free and hazardous substance restrictions.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
