TE Connectivity AMP Connectors 1-2203769-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-2203769-3 is a 2-position rectangular connector housing designed for plug applications with a 0.157" (4.00mm) pitch. This connector features female socket contacts, crimp termination, and latch holder fastening. The housing is constructed from glass-filled polybutylene terephthalate (PBT) in gray color and includes connector position assurance (CPA), sealed design, and terminal position assurance (TPA) features.

The main part is currently in Active product status with 2,438 pieces in stock. Substitute parts may be required due to inventory constraints, packaging format preferences, or specific application requirements where alternative connector series or color specifications are acceptable within the same electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across electrical and mechanical parameters. The primary substitute for 1-2203769-3 is 1-1438608-2, which maintains identical specifications for the following critical parameters:

Substitution-Determining Parameters:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 2
• Pitch: 0.157" (4.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature Range: -40°C ~ 150°C
• Features: Connector Position Assurance (CPA), Sealed, Terminal Position Assurance (TPA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part differs only in connector series designation (Micro Quadlok versus MCON), housing color (Black versus Gray), packaging format (Bulk versus Box), and product status (Last Time Buy versus Active). These differences do not affect electrical or mechanical compatibility in applications where the connector housing specifications are the controlling requirement.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (1-2203769-3): The main part 1-2203769-3 is the preferred selection for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and supply chain stability. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), suitable for standard storage and handling conditions. Current inventory of 2,438 pieces supports immediate procurement requirements.

Substitute Part Selection (1-1438608-2): The substitute part 1-1438608-2 is electrically and mechanically equivalent and may be selected when the main part is unavailable or when bulk packaging is preferred over box packaging. However, this part carries Last Time Buy status, indicating limited future availability. Selection of this substitute should account for the product lifecycle phase and long-term supply requirements. The REACH status for this part is listed as Vendor Undefined, whereas the main part is REACH Unaffected. Both parts maintain identical RoHS3 compliance and MSL 1 ratings.

Color and Series Considerations: The substitute part features black housing color compared to the gray housing of the main part. The connector series designation differs (Micro Quadlok versus MCON), though this does not affect electrical or mechanical compatibility. Applications with specific color requirements or connector series specifications should maintain the main part selection.

Frequently Asked Questions (FAQ)

Q: Are 1-2203769-3 and 1-1438608-2 electrically compatible?

A: Yes. Both parts are electrically equivalent. They share identical contact type (female socket), number of positions (2), pitch (0.157" / 4.00mm), contact termination (crimp), and operating temperature range (-40°C ~ 150°C). Both include identical features: Connector Position Assurance (CPA), sealed design, and Terminal Position Assurance (TPA).

Q: What is the difference between these two parts?

A: The parts differ in four non-electrical aspects: connector series (MCON versus Micro Quadlok), housing color (gray versus black), packaging format (box versus bulk), and product status (active versus last time buy). All electrical and mechanical parameters are identical.

Q: Can I use 1-1438608-2 as a direct replacement for 1-2203769-3?

A: Yes, from an electrical and mechanical standpoint. Both parts are 2-position plug housings with identical pitch, mounting type, fastening mechanism, and insulation material. The substitute part is mechanically compatible with the same contact sets and mating connectors. However, the product status difference should be considered for long-term supply planning.

Q: Does the color difference affect functionality?

A: No. The color difference (gray versus black) is a cosmetic distinction only and does not affect electrical performance, mechanical fit, or thermal characteristics. Both housings are constructed from glass-filled polybutylene terephthalate (PBT) with identical operating temperature ranges.

Q: What does "Last Time Buy" status mean for part 1-1438608-2?

A: Last Time Buy status indicates that the manufacturer has announced the end of production for this part. Existing inventory may be available, but future availability is not guaranteed. For applications requiring long-term supply assurance, the main part 1-2203769-3 (Active status) is the recommended selection.

Q: Are both parts RoHS compliant?

A: Yes. Both 1-2203769-3 and 1-1438608-2 are ROHS3 compliant. The main part is REACH Unaffected, while the substitute part has Vendor Undefined REACH status. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging (1-2203769-3) typically provides smaller quantity units with protective packaging suitable for standard component distribution. Bulk packaging (1-1438608-2) provides larger quantities with minimal packaging, often used for high-volume manufacturing operations. The connector specifications and performance are identical regardless of packaging format.

Q: Can I mix these parts in the same assembly?

A: Yes. Since both parts are electrically and mechanically equivalent with identical pitch, contact configuration, and mounting type, they can be used interchangeably within the same assembly. However, the color difference may be visible in applications where connector appearance is relevant to system aesthetics or identification.

Q: Are contacts included with these housings?

A: No. Both parts are connector housings only. Contacts are not included and must be procured separately. The contact termination type for both parts is crimp, requiring appropriate crimping tools and contact sets compatible with the 4.00mm pitch specification.
