Equivalent & Substitute Parts: 1-2112890-1

Part Overview

The 1-2112890-1 is a 25-position rectangular connector housing manufactured by TE Connectivity Deutsch Connectors. This plug housing is designed for free-hanging, in-line applications with crimp contact termination and latch holder fastening. The connector operates across an industrial temperature range of -40°C to 120°C and is classified as an active product with full RoHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific color or manufacturer preferences require alternative selection.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-2112890-2 is classified as a parametric equivalent to the main part 1-2112890-1 based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Connector Type: Plug
• Number of Positions: 25
• Number of Rows: 4
• Contact Type: Tab
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Operating Temperature Range: -40°C ~ 120°C
• Moisture Sensitivity Level: 1 (Unlimited)

Differentiating Parameter:

• Color: Black (1-2112890-1) versus Gray (1-2112890-2)
• Manufacturer: TE Connectivity Deutsch Connectors versus TE Connectivity AMP Connectors

The color difference and manufacturer designation do not affect electrical or mechanical functionality. Both parts share the same base product number (2112890) and maintain identical performance specifications across all critical operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-2112890-1 and 1-2112890-2 are active products with confirmed compliance certifications. The 1-2112890-1 carries RoHS3 compliance, while the 1-2112890-2 carries RoHS compliance. Both parts are classified under EAR99 export control and maintain identical electrical and mechanical specifications.

Selection between these parts should be based on:

1. Availability: The 1-2112890-2 currently has higher inventory (1255 pieces) compared to the 1-2112890-1 (874 pieces).

2. Color Requirement: If color specification is critical to the application or assembly documentation, the black housing (1-2112890-1) or gray housing (1-2112890-2) must be selected accordingly.

3. Compliance Level: If RoHS3 compliance is specifically required, the 1-2112890-1 is the appropriate selection. If RoHS compliance is sufficient, either part is acceptable.

4. Manufacturer Preference: Both parts are manufactured by TE Connectivity divisions (Deutsch Connectors and AMP Connectors). Selection may depend on existing supply chain relationships or qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1-2112890-2 be used as a direct replacement for the 1-2112890-1?

A: Yes. Both parts are functionally equivalent across all critical electrical and mechanical parameters, including connector type, position count, row configuration, contact type, mounting method, termination style, and operating temperature range. The only differences are color and manufacturer designation within the TE Connectivity family.

Q: Does the color difference affect connector performance?

A: No. Color is a cosmetic and identification feature only. The black (1-2112890-1) and gray (1-2112890-2) housings perform identically in all electrical and mechanical functions.

Q: Are the contacts included with these connector housings?

A: No. Both the 1-2112890-1 and 1-2112890-2 are housings only. Contacts must be sourced separately and crimped into the housing according to the connector's specifications.

Q: What is the difference between RoHS3 and RoHS compliance?

A: RoHS3 represents the most current version of the Restriction of Hazardous Substances directive. The 1-2112890-1 meets RoHS3 standards, while the 1-2112890-2 meets RoHS standards. Both restrict hazardous substances, with RoHS3 including additional restricted substances.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -40°C to 120°C, making them suitable for industrial and automotive applications within this temperature range.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering or assembly.

Q: Are these parts suitable for crimp termination?

A: Yes. Both the 1-2112890-1 and 1-2112890-2 are designed specifically for crimp contact termination. Contacts must be crimped into the housing using appropriate crimping tools and procedures.
