Molex 0022012166 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022012166 is a 16-position receptacle housing for rectangular connectors with a 0.100" (2.54mm) pitch, designed for crimp contact termination in free-hanging inline applications. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement planning. The housing accommodates non-gendered contacts and is compliant with ROHS3 standards with MSL 1 rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022012166 is determined by the following critical parameters:

• Connector type (Receptacle)
• Number of positions (16)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Contact termination method (Crimp)
• Contact gender classification (Non-Gendered)

The substitute part Molex 0022012161 satisfies all these core electrical and mechanical parameters. The primary difference is the housing color (Natural vs. White) and series designation, which do not affect functional compatibility or electrical performance in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022012161 is the direct substitute for the obsolete Molex 0022012166. Both parts maintain identical electrical and mechanical specifications across all critical parameters: 16-position receptacle configuration, 2.54mm pitch, single-row layout, and crimp termination compatibility.

The 0022012161 is currently in active production status with substantial inventory availability (8716 pcs), whereas the 0022012166 is obsolete. Both parts carry ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and regulatory performance.

The housing color difference (Natural to White) is a cosmetic variation that does not impact electrical function, mechanical fit, or contact performance. The 0022012161 provides superior long-term supply chain security and design continuity for new applications or redesigns of existing products currently using the 0022012166.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022012161 be used as a direct replacement for the 0022012166 in existing designs?

A: Yes. Both housings share identical electrical and mechanical specifications: 16 positions, 0.100" pitch, single-row receptacle configuration, and crimp termination. The only difference is housing color, which does not affect functional compatibility.

Q: Why is the 0022012166 listed as obsolete?

A: Obsolescence typically reflects end-of-life status in the manufacturer's product line. The 0022012161 represents the active equivalent in Molex's current KK254 series portfolio.

Q: Are the contacts interchangeable between these two housings?

A: Yes. Both housings accept the same non-gendered crimp contacts designed for 2.54mm pitch KK254 series connectors. Contacts are not included with either housing and must be sourced separately.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures.

Q: Does the operating temperature specification difference affect substitution?

A: The 0022012161 specifies -40°C to 105°C operating range. This represents the documented thermal performance of the active part. The 0022012166 does not include published temperature data. For applications requiring confirmed thermal specifications, the 0022012161 provides documented performance parameters.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 0022012166 and 0022012161 meet ROHS3 compliance requirements, ensuring compatibility with regulatory standards for restricted substance use.
