Molex 0705450080 Equivalent & Substitute Parts

Part Overview

The Molex 0705450080 is an 11-position vertical header connector with 0.100" (2.54mm) pitch, designed for through-hole mounting in board-to-cable/wire applications. This shrouded, single-row connector features gold-plated mating contacts and tin-plated posts, with phosphor bronze contact material and polyester glass-filled insulation. The connector is classified as Active product status and is ROHS3 compliant, making it suitable for automotive, general purpose, industrial, and medical applications. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (Molex 0705450080): Select the Molex 0705450080 when ROHS3 compliance is a mandatory requirement. This part maintains active product status and meets all regulatory compliance standards including REACH unaffected designation. The phosphor bronze contact material and polyester glass-filled insulation provide specified performance characteristics for the intended application range.

Substitute Part Selection (TE Connectivity 1-103908-0): The TE Connectivity 1-103908-0 serves as a functional equivalent for applications where RoHS compliance is not required. This substitute offers an extended lower operating temperature limit (-65°C vs. -40°C), providing broader thermal performance capability. The press-fit termination option in addition to solder termination offers design flexibility. However, note that this substitute is RoHS non-compliant and REACH affected, which may restrict use in regulated markets or applications with environmental compliance mandates.

Compliance Considerations: Applications requiring ROHS3 compliance must use the Molex 0705450080. Applications with no RoHS requirement may use either part based on thermal and termination requirements. Both parts share identical electrical and mechanical mating characteristics, ensuring pin-to-pin compatibility in standard 2.54mm pitch header applications.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0705450080 and TE Connectivity 1-103908-0 pin-to-pin compatible?

A: Yes. Both connectors feature 11 positions in a single row with 0.100" (2.54mm) pitch, square contact geometry, and identical mating contact dimensions. They are mechanically and electrically interchangeable at the mating interface.

Q: What is the primary difference between these two connectors?

A: The primary difference is regulatory compliance. The Molex part is ROHS3 compliant, while the TE Connectivity part is RoHS non-compliant. Secondary differences include contact material (phosphor bronze vs. brass), insulation material (polyester glass-filled vs. thermoplastic), and operating temperature range (-40°C to 105°C vs. -65°C to 105°C).

Q: Can I use the TE Connectivity 1-103908-0 in an automotive application?

A: Both connectors list automotive applications in their specifications. However, automotive applications often require RoHS compliance. Verify your specific automotive standard requirements before selecting the TE Connectivity substitute, as its RoHS non-compliant status may not meet your application's regulatory requirements.

Q: What does the 4-wall shrouding provide?

A: The 4-wall shrouding on both connectors provides mechanical protection and polarization guidance during mating. This design prevents incorrect connector orientation and protects the contact pins from accidental contact or contamination.

Q: Are both connectors suitable for medical applications?

A: Both connectors list medical applications in their specifications and share UL94 V-0 flammability ratings. However, medical device applications often require specific compliance certifications beyond those listed in the basic specifications. Consult your medical device regulatory requirements and the manufacturers' detailed compliance documentation before final selection.

Q: What is the difference between solder and press-fit termination?

A: The Molex part uses solder termination exclusively. The TE Connectivity substitute offers both press-fit and solder termination options. Press-fit termination provides faster assembly without soldering, while solder termination requires thermal processing but may provide stronger mechanical bonds in high-vibration environments.

Q: Does the extended temperature range of the TE Connectivity part affect compatibility?

A: No. The TE Connectivity part's extended lower temperature limit (-65°C vs. -40°C) is a superset of the Molex part's range. This means the TE Connectivity part can operate in all conditions where the Molex part operates, plus additional lower-temperature conditions. Compatibility is maintained.
