Substitute Part Grouping Explanation

The Molex 0734154490 qualifies as a parametric equivalent to the 0734154491 based on identical electrical and mechanical specifications. Both parts share the same MCX connector style, male pin configuration, 75 ohm impedance, solder contact termination, crimp shield termination, free hanging mounting type, RG-179 cable compatibility, snap-on fastening, 6 GHz maximum frequency, and 335 V voltage rating. Material composition, finish specifications, and dielectric properties are identical across both parts.

The primary distinction between these parts is packaging format: the 0734154491 is supplied in bag packaging, while the 0734154490 is supplied in bulk packaging. The 0734154490 additionally provides documented operating temperature range (-55°C to 155°C), mating cycle rating (500 cycles), and compliance certifications (RoHS3, REACH Affected, MSL 1) that are not specified in the 0734154491 datasheet.

Substitution is valid when packaging requirements align and documented specifications meet application needs.

Parameter Comparison

Engineering Selection Recommendations

Both the 0734154491 and 0734154490 maintain active product status and are manufactured by Molex within the same 73415 series. Selection between these parts is determined by packaging requirements and compliance documentation needs.

The 0734154491 in bag packaging is suitable for applications requiring smaller quantities or specific packaging constraints. The 0734154490 in bulk packaging is appropriate for high-volume procurement and provides explicit RoHS3 compliance and REACH status documentation. The 0734154490 additionally documents operating temperature range (-55°C to 155°C) and mating cycle rating (500 cycles), which may be required for design verification in temperature-sensitive or high-cycle applications.

Both parts are electrically and mechanically identical across all specified parameters: 75 ohm impedance, 6 GHz frequency capability, solder termination, and RG-179 cable compatibility. Selection should be based on packaging format availability, compliance documentation requirements, and procurement volume.

Frequently Asked Questions (FAQ)

Q: Are the 0734154491 and 0734154490 electrically interchangeable?

A: Yes. Both parts are identical in electrical performance: 75 ohm impedance, 6 GHz maximum frequency, 335 V voltage rating, and solder contact termination with crimp shield termination. Mechanical dimensions and connector interface are identical.

Q: What is the difference between bag and bulk packaging?

A: The 0734154491 is supplied in bag packaging, typically used for smaller order quantities. The 0734154490 is supplied in bulk packaging, designed for high-volume orders. The connector itself is identical; only the packaging format differs.
