Molex 0705510079 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0705510079 is a shrouded right-angle header connector with 10 positions at 2.54mm pitch, designed for through-hole mounting in board-to-cable applications. This connector features male pins with gold-plated mating contacts and tin-plated posts, housed in a polyester glass-filled insulation body with board lock fastening. The part is currently active in production with 967 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0705510079 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 10 positions at 0.100" (2.54mm) mating pitch
• Mounting Orientation: Through-hole, right-angle configuration
• Shrouding Design: 4-wall shrouded housing with board lock
• Contact Finish: Gold-plated mating surface
• Termination Method: Solder attachment
• Electrical Rating: Voltage and current capacity within application requirements
• Environmental Compliance: UL94 V-0 flammability rating

The TE Connectivity AMP Connectors part 103904-9 meets these core substitution criteria, providing functional equivalence for applications requiring a 10-position right-angle header with 2.54mm pitch and shrouded design.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - Molex 0705510079: Select this part for applications requiring ROHS3 compliance. The part is active in production with established supply availability and meets all standard electrical and mechanical requirements for 10-position 2.54mm pitch header applications.

Substitute Part - TE Connectivity 103904-9: This part provides functional equivalence for applications where RoHS3 compliance is not a requirement. The TE part offers an extended operating temperature range (-65°C to 105°C versus -40°C to 105°C) and specified current rating of 3A. Minor dimensional variations in contact length and insulation height fall within acceptable mechanical tolerances for standard board-to-cable header applications. The part is active in production with higher inventory availability (1196 units).

Regulatory Consideration: The Molex part carries ROHS3 compliance certification, while the TE part is marked as RoHS non-compliant. Applications subject to RoHS regulations must use the Molex 0705510079.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 103904-9 be used as a direct replacement for Molex 0705510079?

A: The TE part is mechanically and electrically compatible for standard board-to-cable header applications. Both connectors share identical pitch (2.54mm), position count (10), mounting type (through-hole right-angle), shrouding design (4-wall), and contact finish (gold-plated mating surface). Minor dimensional differences in contact length (0.240" vs 0.230") and insulation height (0.215" vs 0.200") are within acceptable tolerances. However, regulatory compliance differs: the Molex part is ROHS3 compliant while the TE part is not. Selection depends on application requirements.

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

A: The primary differences are: (1) Insulation material—Molex uses polyester glass-filled while TE uses thermoplastic; (2) Contact base material—Molex uses phosphor bronze while TE uses brass; (3) Operating temperature range—TE extends to -65°C while Molex starts at -40°C; (4) RoHS compliance—Molex is ROHS3 compliant, TE is not; (5) Packaging—Molex is bulk, TE is tube; (6) Current rating specification—TE specifies 3A, Molex does not specify. Both maintain UL94 V-0 flammability rating and equivalent electrical performance.

Q: Are there any mechanical compatibility issues when substituting these parts?

A: No significant compatibility issues exist. The contact length difference of 0.010" (0.26mm) and insulation height difference of 0.015" (0.38mm) are minor variations that do not affect mating with standard 2.54mm pitch receptacles or PCB mounting. Both parts use identical solder termination and latch holder fastening, ensuring equivalent board integration.

Q: Which part should I select for new designs?

A: For new designs subject to RoHS regulations, specify Molex 0705510079. For applications without RoHS requirements where extended low-temperature operation (-65°C) is beneficial, TE Connectivity 103904-9 is suitable. Both parts are active in production with stable supply.

Q: What is the difference in packaging between these parts?

A: Molex 0705510079 is supplied in bulk packaging, while TE Connectivity 103904-9 is supplied in tube packaging. Bulk packaging typically offers cost advantages for high-volume procurement, while tube packaging provides organized component handling and counting. This difference does not affect connector performance or compatibility.
