Molex 5054050270 Equivalent & Substitute Parts

Part Overview

The Molex 5054050270 is a 2-position receptacle connector from the CLIK-Mate 505405 series, designed for surface mount applications with 0.059" (1.50mm) pitch mating. This connector features gold-plated forked contacts, solder termination, and is rated for -40°C to 105°C operation with 100V voltage rating. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Direct replacements from the active CLIK-Mate 213225 series provide functional equivalence with improved availability and manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 5054050270 is determined by the following critical parameters that must remain constant across all equivalent parts:

• Connector Type & Position Count: All substitutes must be 2-position receptacles
• Mating Pitch: All substitutes must maintain 0.059" (1.50mm) pitch
• Mounting Technology: All substitutes must be surface mount (SMD/SMT)
• Contact Configuration: All substitutes must feature forked contacts with solder termination
• Electrical Ratings: All substitutes must support 100V minimum voltage rating and -40°C to 105°C operating temperature
• Compliance: All substitutes must maintain ROHS3 compliance and UL94 V-0 flammability rating

The three qualified substitutes (2132250270, 2132250230, 2132250210) meet these criteria while offering improved product status and availability. Variations in contact finish thickness and insulation material do not affect functional compatibility within the specified electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (2132250270, 2132250230, 2132250210) are functionally equivalent to the obsolete 5054050270 and meet identical electrical, thermal, and compliance requirements. Selection among substitutes should be based on the following factors:

Product Status & Availability: All substitutes are active products with established manufacturing support, eliminating obsolescence risk. Inventory levels vary, with 2132250230 offering the highest stock position (13,871 pcs).

Packaging Considerations: The main part is supplied in Cut Tape (CT) format, while all substitutes are available in Tape & Reel (TR) format. TR packaging is standard for automated assembly processes and provides cost advantages for high-volume production.

Contact Finish Specifications: The substitutes offer three distinct gold plating thicknesses (0.100µm, 0.38µm, and 0.76µm) compared to the main part's 0.203µm. All thicknesses provide equivalent corrosion resistance and electrical performance within the specified voltage and temperature parameters.

Insulation Material: The main part uses Beige resin insulation, while substitutes use Polyamide (PA) Nylon. Both materials meet UL94 V-0 flammability requirements and operate within identical temperature ranges.

Compliance Certification: All parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across automotive, industrial, medical, and general purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 2132250270, 2132250230, or 2132250210 be used as direct replacements for the 5054050270?

A: Yes. All three parts are functionally equivalent substitutes. They maintain identical connector type, position count, mating pitch (0.059"), mounting technology (surface mount), contact configuration (forked solder termination), and electrical ratings (100V, -40°C to 105°C). The primary difference is product status—the substitutes are active products with established supply chains.

Q: What is the difference between the three substitute parts?

A: The substitutes differ in contact finish thickness and insulation material. Part 2132250270 features 0.76µm gold plating, 2132250230 features 0.38µm gold plating, and 2132250210 features 0.100µm gold plating. All three thicknesses provide equivalent electrical performance and corrosion resistance within the specified operating parameters. Insulation material varies between Beige resin (main part) and Polyamide Nylon (substitutes), but both meet UL94 V-0 requirements.

Q: Does the packaging format (Cut Tape vs. Tape & Reel) affect compatibility?

A: No. Packaging format does not affect electrical or mechanical compatibility. Cut Tape (CT) is suitable for manual assembly or low-volume applications, while Tape & Reel (TR) is optimized for automated pick-and-place assembly. Selection should be based on production volume and assembly process requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All three substitute parts and the main part are ROHS3 compliant and REACH Unaffected, meeting regulatory requirements for automotive, industrial, medical, and general purpose applications.

Q: Which substitute should I select for new designs?

A: For new designs, any of the three active substitutes is acceptable. Selection should prioritize availability (2132250230 has the highest inventory), packaging format (TR for automated assembly), and contact finish thickness based on application-specific corrosion or wear requirements. All three parts provide identical electrical and thermal performance.
