Molex 0009523091 Equivalent & Substitute Parts

Part Overview

The Molex 0009523091 is a 9-position receptacle connector with 0.156" (3.96mm) pitch, designed for board edge, through-hole, right-angle mounting applications. This connector is part of the KK396 and 2145 series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from the same manufacturer are available to ensure design continuity and supply chain reliability for applications in automotive, general purpose, medical, and telecommunications sectors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0009523091 is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle with 9 positions
• Pitch & Mounting: Must maintain 0.156" (3.96mm) pitch and board edge, through-hole, right-angle mounting
• Electrical Ratings: Voltage rating of 600V and current rating of 4.5A or higher
• Termination & Contact Type: Solder termination with female socket contacts
• Compliance: ROHS3 compliance required

The two substitute parts listed below meet these core substitution criteria while maintaining functional and electrical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

0009481094: This substitute is the preferred option for new designs and applications requiring extended operating temperature range. It offers active product status, higher current rating (5A vs. 4.5A), and superior flammability rating (UL94 V-0). The extended temperature range (-40°C ~ 105°C) provides additional thermal margin for demanding applications. Contact material is phosphor bronze, which offers enhanced durability compared to brass.

0009482091: This substitute maintains identical electrical specifications to the original part (4.5A current rating, -40°C ~ 80°C operating range) while providing active product status and improved flammability rating (UL94 V-0). It is suitable for direct replacement in existing designs where the original specifications are fully adequate. Both substitutes are ROHS3 compliant and carry unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can 0009481094 and 0009482091 be used interchangeably with 0009523091?

A: Both substitutes are mechanically and electrically compatible with the original part. They share identical connector type, position count, pitch, mounting configuration, and termination method. The primary differences are product status (active vs. obsolete), contact material composition, and operating temperature range. Selection depends on application requirements.

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

A: The key differences are: (1) 0009481094 has a higher current rating (5A vs. 4.5A) and extended operating temperature range (-40°C ~ 105°C vs. -40°C ~ 80°C), with phosphor bronze contacts; (2) 0009482091 maintains the original 4.5A rating and -40°C ~ 80°C range with brass contacts. Both have superior flammability ratings (UL94 V-0) compared to the original.

Q: Are there packaging differences between these parts?

A: The original part 0009523091 is listed without specified packaging. Both substitutes are supplied in Tray packaging, which is standard for production quantities.

Q: Do all three parts meet RoHS compliance?

A: Yes, all three parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Which substitute should I select for a new design?

A: For new designs, 0009481094 is recommended due to its active product status, extended temperature range, higher current rating, and superior flammability rating. For applications with existing thermal and current specifications matching the original part, 0009482091 provides a direct functional equivalent with active availability.
