Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0521160342 are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters determine substitution eligibility:

Core Substitution Criteria:

• Connector type (Plug)
• Contact type (Male Pin)
• Number of positions (3)
• Pitch (0.098" / 2.50mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening type (Detent Lock)
• Waterproof rating (IP67 mated)
• Insulation material (Polyester, Glass Filled)
• Operating temperature range (-40°C to 105°C)
• RoHS3 compliance

All substitute parts listed maintain these parameters identically. Variations in color and product status do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Molex 0521160341

The 0521160341 is the recommended substitute for the obsolete 0521160342. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, waterproof rating, and operating temperature range. The 0521160341 maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Higher inventory availability (3,657 units) supports production continuity.

Secondary Substitute: Molex 0522660311

The 0522660311 provides an alternative substitute with identical parametric specifications. This part belongs to the Mizu-P25 Waterproof series (base product 052266) and maintains all critical electrical and mechanical parameters. Active product status and substantial inventory (4,739 units) ensure supply reliability.

Alternative Substitute: Molex 0521160340

The 0521160340 offers a third substitution option with complete parametric equivalence. This part is packaged in trays and maintains active product status. REACH compliance differs from the main part; however, this does not affect functional compatibility.

All three substitute parts are suitable for direct replacement in applications currently using the 0521160342, provided system design accommodates color variation where applicable.

Frequently Asked Questions (FAQ)

Q: Can the 0521160340, 0521160341, and 0522660311 be used interchangeably with the 0521160342?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications including connector type, contact configuration, pitch, number of positions, mounting type, contact termination, fastening mechanism, waterproof rating, insulation material, and operating temperature range. Substitution is functionally valid.

Q: What is the difference between the substitute parts?

A: The primary differences are color (white for 0521160340, black for 0521160341 and 0522660311) and product status (all substitutes are active versus the obsolete main part). The 0522660311 belongs to a different base product series (052266 versus 052116) but maintains identical parametric specifications. Packaging format differs between tray and original packaging.

Q: Does the color difference affect compatibility?

A: Color is a cosmetic parameter that does not affect electrical or mechanical compatibility. Selection should be based on system design requirements and visual identification needs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the main part specification.

Q: What is the moisture sensitivity level, and does it differ between parts?

A: All parts, including the main part and substitutes, have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can I mix connector housings from different substitute parts in the same assembly?

A: Yes. Since all parts maintain identical electrical and mechanical specifications, they can be used together in the same assembly. Color consistency may be a design consideration depending on application requirements.

Q: What is the inventory status for each part?

A: The 0521160342 (main part) has 689 units in stock but is obsolete. Active substitutes have higher availability: 0521160341 (3,657 units), 0522660311 (4,739 units), and 0521160340 (1,575 units).
