Molex 0022011122 Equivalent & Substitute Parts

Part Overview

The Molex 0022011122 is a 12-position rectangular connector housing (receptacle) with 0.098" (2.50mm) pitch, designed for free-hanging in-line applications. This part belongs to the KK250 and 5051 series and features a polarizing key for proper mating orientation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repairs, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0022011122 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle
• Number of positions: 12
• Pitch: 0.098" (2.50mm)
• Mounting type: Free Hanging (In-Line)
• Contact termination: Crimp
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Two substitute parts meet these core requirements:

JST EHR-12 matches the original part exactly on pitch (2.50mm), position count (12), and mounting configuration. This part is active and maintains identical electrical and mechanical specifications.

TE Connectivity 1-1375820-2 provides functional equivalence with a pitch of 0.100" (2.54mm), which represents a 0.002" (0.04mm) deviation from the original specification. This part is active and includes a locking ramp fastening feature not present in the original design.

Parameter Comparison

Engineering Selection Recommendations

JST EHR-12 is the primary substitute for the Molex 0022011122. This part maintains exact pitch compatibility (2.50mm), identical position count (12), and matching mechanical configuration. Both parts are ROHS3 compliant with MSL rating 1. The JST part is currently in active production with 1583 units in stock, ensuring supply continuity for legacy system support.

TE Connectivity 1-1375820-2 serves as a secondary substitute when pitch tolerance of 0.002" (0.04mm) is acceptable within system design margins. This part offers extended operating temperature range (-55°C to 105°C versus -25°C to 85°C for the JST part) and includes a locking ramp fastening mechanism. The 0.100" (2.54mm) pitch represents a minor deviation that may require PCB layout verification before implementation.

Both substitute parts are ROHS3 compliant, carry MSL rating 1, and support crimp contact termination consistent with the original design.

Frequently Asked Questions (FAQ)

Q: Can the JST EHR-12 directly replace the Molex 0022011122?

A: Yes. The JST EHR-12 matches all critical parameters: 12 positions, 0.098" (2.50mm) pitch, receptacle type, free-hanging in-line mounting, and crimp termination. Both parts are ROHS3 compliant with MSL rating 1.

Q: What is the pitch difference between the Molex part and the TE Connectivity substitute?

A: The TE Connectivity 1-1375820-2 has a pitch of 0.100" (2.54mm) compared to the original 0.098" (2.50mm). This represents a 0.002" (0.04mm) deviation per position. Verify PCB layout compatibility before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The Molex 0022011122, JST EHR-12, and TE Connectivity 1-1375820-2 are all ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity).

Q: What is the difference in operating temperature ranges?

A: The JST EHR-12 operates from -25°C to 85°C. The TE Connectivity 1-1375820-2 operates from -55°C to 105°C, providing a wider thermal envelope. The original Molex part does not specify an operating temperature range.

Q: Does the TE Connectivity part include any additional features?

A: Yes. The TE Connectivity 1-1375820-2 includes a locking ramp fastening mechanism, whereas the original Molex part and JST EHR-12 do not specify this feature. This provides enhanced mating security in applications requiring positive locking.

Q: What packaging options are available for substitute parts?

A: The JST EHR-12 and TE Connectivity 1-1375820-2 are both supplied in bulk packaging. Inventory availability: JST EHR-12 (1583 units), TE Connectivity 1-1375820-2 (15954 units).
