TE Connectivity AMP Connectors 2238026-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2238026-2 is a 0.250" (6.35mm) Quick Connect Female Crimp Connector designed for 12-22 AWG wire gauges. This non-insulated Faston series terminal operates as a free-hanging in-line connector with brass contact material and tin finish. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and design applications. Substitute parts must maintain electrical and mechanical compatibility within the Quick Connect terminal family while meeting current product availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2238026-2 is based on strict electrical and mechanical parameter alignment within the Quick Connect terminal category. The primary substitution criteria are:

Critical Matching Parameters:

• Tab width: 0.250" (6.35mm) — ensures mechanical fit with mating connectors
• Tab thickness: 0.032" (0.81mm) — maintains contact pressure and electrical performance
• Terminal type: Standard — preserves functional classification
• Gender: Female — ensures correct mating orientation
• Termination method: Crimp — maintains assembly compatibility
• Contact material and finish: Brass with tin — ensures electrical conductivity and corrosion resistance
• Mounting type: Free Hanging (In-Line) — preserves installation configuration
• Insulation: Non-Insulated — maintains electrical characteristics

Secondary Compatibility Factors:

• Wire gauge range overlap — substitute must accommodate the application wire gauge
• RoHS compliance — ensures regulatory alignment
• Series compatibility — Faston and Fastin-Faston series maintain cross-compatibility within the Quick Connect family

The substitute part 4-170031-2 meets all critical matching parameters. Wire gauge range differs (14-20 AWG vs. 12-22 AWG), creating a subset relationship where the substitute accommodates a narrower but overlapping wire gauge range suitable for applications within the 14-20 AWG specification.

Parameter Comparison

Engineering Selection Recommendations

The 4-170031-2 serves as the active equivalent for the obsolete 2238026-2 based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical tab width (0.250"), tab thickness (0.032"), and mounting configuration, ensuring direct mechanical interchangeability with mating connectors and circuit board receptacles.

Electrical Compatibility: Identical contact material (brass), contact finish (tin), and termination method (crimp) preserve electrical performance characteristics and connection reliability.

Regulatory Compliance: Both parts maintain RoHS compliance, satisfying environmental and regulatory requirements for current applications.

Product Status Advantage: The 4-170031-2 is classified as active product status with significantly higher inventory availability (31,396 pcs vs. 925 pcs), ensuring long-term procurement viability and supply chain continuity.

Wire Gauge Consideration: The substitute part accommodates 14-20 AWG wire gauges, which represents a subset of the original 12-22 AWG range. Applications requiring wire gauges of 12-13 AWG or 21-22 AWG fall outside the substitute's specification and require alternative solutions or direct sourcing of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 4-170031-2 directly replace the 2238026-2 in all applications?

A: Direct replacement is applicable for applications using wire gauges within the 14-20 AWG range. Applications requiring 12-13 AWG or 21-22 AWG wire gauges require alternative component selection, as the substitute part does not accommodate these wire gauge extremes.

Q: What are the key mechanical differences between these parts?

A: The parts are mechanically identical in critical dimensions: tab width, tab thickness, and mounting type. Tab length differs by 0.002" (0.05mm), which is within normal manufacturing tolerance and does not affect functional compatibility.

Q: Are both parts compatible with the same mating connectors?

A: Yes. Both parts feature identical tab width (0.250") and thickness (0.032"), ensuring compatibility with the same Quick Connect receptacles and mating components.

Q: Does the wire gauge range difference affect electrical performance?

A: Wire gauge range specification defines the acceptable conductor sizes for crimp termination. The substitute part's 14-20 AWG range is narrower but fully functional within that specification. Applications using wire gauges outside this range require components rated for those specific gauges.

Q: What is the significance of the series designation change from Faston to Fastin-Faston?

A: Both designations refer to the Quick Connect terminal family. The Fastin-Faston designation indicates an updated product line within the same mechanical and electrical family, maintaining full compatibility with Faston series mating components.

Q: Why is the substitute part recommended despite the wire gauge range difference?

A: The substitute is recommended for applications within the 14-20 AWG specification due to active product status, superior inventory availability, and identical mechanical and electrical characteristics. The original part's obsolete status creates long-term procurement risk.

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in Cut Tape (CT) packaging. The substitute part carries Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
