Molex 0010012129 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0010012129 is a 12-position receptacle housing for rectangular connectors with 0.100" (2.54mm) pitch spacing. This component is part of the KK254 and 7880 series and is designed for free-hanging, in-line applications using crimp termination. The housing is manufactured from polyamide (PA) nylon in white and does not include contacts.

This part maintains Active product status and is ROHS3 compliant. Substitute parts are identified based on matching electrical and mechanical parameters that ensure functional equivalence in connector applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0010012129 are qualified based on the following critical parameters:

• Connector type (Receptacle)
• Number of positions (12)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (Free Hanging, In-Line)
• Contact termination method (Crimp)
• Insulation material (Polyamide/Nylon)
• Housing color (White)
• Contact type (Non-Gendered)

The substitute part Molex 0022012121 matches all these parameters, making it functionally equivalent for applications requiring a 12-position KK254-series receptacle housing with 2.54mm pitch spacing.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0010012129 and 0022012121 are Active products with identical compliance certifications (ROHS3, REACH Unaffected). The substitute part 0022012121 demonstrates full parametric equivalence across all specified electrical and mechanical characteristics.

Selection between these parts may be based on availability and inventory levels. The 0022012121 currently maintains higher inventory availability (15,885 pcs) compared to the 0010012129 (666 pcs), which may influence procurement decisions for high-volume applications.

Both parts are suitable for direct substitution in applications requiring 12-position KK254-series receptacle housings with 2.54mm pitch spacing and crimp termination.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022012121 be used as a direct replacement for the 0010012129?

A: Yes. Both parts are functionally equivalent receptacle housings with identical electrical and mechanical specifications: 12 positions, 0.100" (2.54mm) pitch, single-row configuration, crimp termination, and polyamide nylon construction.

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

A: The parts differ in series designation (7880 vs. 2695) and base product number (001001 vs. 002201), but maintain identical functional parameters. Both are manufactured by Molex and comply with ROHS3 and REACH requirements.

Q: Are contacts included with these housings?

A: No. Both the 0010012129 and 0022012121 are housings only. Contacts must be sourced separately and crimped into the housing.

Q: What is the operating temperature range for these connectors?

A: The 0022012121 specifies an operating temperature range of -40°C to 105°C. The 0010012129 does not include operating temperature specification in the provided data.

Q: Are these parts suitable for high-volume production?

A: Both parts are Active products with ROHS3 compliance suitable for production applications. The 0022012121 offers higher inventory availability, which may be advantageous for high-volume procurement.
