Molex 0459713183 Equivalent & Substitute Parts

Part Overview

The Molex 0459713183 is a 240-position high-density array rectangular connector with female receptacle configuration, designed for surface mount applications. This connector features gold-plated contacts and board guide support, with a 0.050" (1.27mm) pitch across 8 rows. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts maintain identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0459713183 is determined by strict equivalence across the following critical parameters:

• Connector type and gender (High Density Array, Female)
• Position count (240 positions)
• Contact pitch (0.050" / 1.27mm)
• Row configuration (8 rows)
• Mounting technology (Surface Mount)
• Contact material and finish specifications (Gold, 30.0µin thickness)
• Physical envelope (Height above board: 0.199")
• Mated stacking height compatibility (7mm through 12mm range)
• Board guide feature presence

The identified substitute part maintains 100% equivalence across all specified electrical and mechanical parameters. Substitution is driven by product lifecycle status and regulatory compliance improvements rather than functional differences.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0459713185 is the direct substitute for the obsolete 0459713183. Both parts are functionally identical across all electrical and mechanical specifications. The primary differentiators are product lifecycle status and regulatory compliance:

The 0459713185 carries Active product status, ensuring continued manufacturer support, availability, and technical documentation. The substitute achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions applicable to electronic components in regulated markets. The original part is classified as RoHS non-compliant, which may present sourcing and regulatory challenges in new designs or production environments with compliance requirements.

For applications requiring RoHS compliance or long-term component availability, the 0459713185 is the appropriate selection. For legacy systems or applications without compliance mandates, either part satisfies the functional requirements identically.

Frequently Asked Questions (FAQ)

Q: Are the 0459713183 and 0459713185 electrically interchangeable?

A: Yes. Both parts are identical in electrical specifications, including contact pitch (0.050"), position count (240), contact material (gold finish at 30.0µin thickness), and all signal integrity parameters.

Q: Are these connectors mechanically interchangeable?

A: Yes. The parts share identical mechanical envelopes, mounting footprints, height above board (0.199"), mated stacking heights (7mm–12mm range), and board guide features. No PCB redesign is required for substitution.

Q: What is the difference between these two part numbers?

A: The 0459713185 is the current production equivalent of the obsolete 0459713183. The substitute offers Active product status and ROHS3 compliance. All functional and mechanical parameters are identical.

Q: Can I use the 0459713185 in place of the 0459713183 in existing designs?

A: Yes. The substitute is a direct replacement with no design modifications required. Existing PCB layouts, mating connectors, and assembly processes remain unchanged.

Q: What is the packaging difference?

A: The 0459713183 packaging is not specified in the available data. The 0459713185 is supplied in Cut Tape (CT) packaging. Confirm packaging requirements with your procurement specifications.

Q: Are there any compliance or certification differences?

A: The 0459713185 is ROHS3 compliant and REACH unaffected, while the 0459713183 is RoHS non-compliant. For applications in regulated markets or with compliance mandates, the 0459713185 is required.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply.
