Molex 0705510089 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0705510089 is an active-status rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded 20-position header with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection requirements across automotive, industrial, medical, and general-purpose applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0705510089 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 20 positions, single row
• Mating Pitch: 0.100" (2.54mm)
• Mounting Orientation: Through hole, right-angle
• Shrouding Design: Shrouded with 4-wall construction
• Termination Method: Solder
• Fastening Mechanism: Latch holder
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The TE Connectivity AMP Connectors part number 6-103904-9 qualifies as a substitute based on matching all critical parameters. Both parts share identical mating pitch, position count, row configuration, mounting type, shrouding style, termination method, and fastening type. Both maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0705510089 and TE Connectivity 6-103904-9 maintain active product status and meet UL94 V-0 flammability requirements with RoHS compliance. The TE Connectivity part provides an extended operating temperature range (-65°C to 105°C versus -40°C to 105°C), which accommodates broader environmental specifications. The Molex part specifies a 250V voltage rating, while the TE part specifies 3A current rating. Selection between these parts should be based on specific application requirements regarding temperature extremes, voltage/current specifications, and design compatibility with the respective contact materials and insulation compositions.

Frequently Asked Questions (FAQ)

Q: What determines if a connector header can substitute for the Molex 0705510089?

A: Substitution requires matching on connector type (header), contact type (male pin), position count (20), row configuration (1), mating pitch (0.100"/2.54mm), mounting type (through hole, right angle), shrouding style (shrouded 4-wall), termination method (solder), and fastening type (latch holder). Compliance certifications including UL94 V-0 and RoHS status must also align.

Q: Are there dimensional differences between the Molex and TE Connectivity parts?

A: Yes. The contact length at mating differs: Molex specifies 0.240" (6.10mm) while TE Connectivity specifies 0.230" (5.84mm). Insulation height also varies: Molex at 0.215" (5.45mm) versus TE Connectivity at 0.200" (5.08mm). These variations may affect mechanical fit in constrained board layouts.

Q: What is the difference in contact material between these parts?

A: The Molex 0705510089 uses phosphor bronze contacts, while the TE Connectivity 6-103904-9 uses brass contacts. Both materials are suitable for general-purpose, automotive, industrial, and medical applications with gold plating on mating surfaces.

Q: Do both parts support the same operating temperature range?

A: No. The Molex part operates from -40°C to 105°C, while the TE Connectivity part operates from -65°C to 105°C. Applications requiring operation below -40°C should use the TE Connectivity part.

Q: What packaging differences exist between these parts?

A: The Molex 0705510089 is supplied in bulk packaging, while the TE Connectivity 6-103904-9 is supplied in tube packaging. This affects handling, storage, and inventory management but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. The Molex part is ROHS3 compliant, and the TE Connectivity part is RoHS compliant. Both meet environmental compliance requirements for restricted substance elimination.
