TE Connectivity AMP Connectors 1438426-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1438426-1 is a 2-position rectangular connector plug housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This connector features female socket contacts with crimp termination and includes Connector Position Assurance (CPA) and Terminal Position Assurance (TPA) safety features. The housing is constructed from polyamide (PA) nylon material in black color.

The 1438426-1 carries a Last Time Buy product status, indicating discontinued production. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production, repair, and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the 1438426-1 are identified based on electrical and mechanical parameter equivalence within the TE Connectivity AMP Connectors rectangular connector product line. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Connector type (Plug)
• Contact type (Female Socket)
• Number of positions (2)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)

Mechanical Parameters:

• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening type (Latch Holder)
• Insulation material (Polyamide/Nylon)
• Safety features (CPA, Sealed, TPA)

Compliance Parameters:

• RoHS3 compliance
• MSL rating (1 - Unlimited)
• Series designation (0.64)

Substitute parts maintain identical electrical and mechanical specifications while differing only in housing color or packaging configuration. These variations do not affect functional compatibility or performance in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 1438426-3 is a direct functional equivalent to the 1438426-1 for rectangular connector applications requiring 2-position, 0.100" pitch plug housings with female socket contacts.

Selection Basis:

The 1438426-3 maintains full electrical and mechanical compatibility with the 1438426-1 across all critical parameters: connector type, contact configuration, position count, pitch specification, mounting method, termination type, and safety features. Both parts are manufactured by TE Connectivity within the same AMP Connectors series (0.64) and carry identical RoHS3 compliance and MSL ratings.

The primary distinction is product status: the 1438426-1 is designated Last Time Buy, while the 1438426-3 maintains Active status. This status difference indicates ongoing availability and production support for the 1438426-3, making it the appropriate selection for new designs and ongoing production requirements.

Housing color (black versus gray) and packaging configuration (unspecified versus bulk) represent non-functional variations that do not affect electrical performance or mechanical fit in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the 1438426-3 be used as a direct replacement for the 1438426-1 in existing designs?

A: Yes. The 1438426-3 is electrically and mechanically equivalent to the 1438426-1. Both parts share identical connector type, contact configuration, pitch, mounting method, termination type, and safety features. The housing color difference does not affect functional compatibility.

Q: What is the significance of the Last Time Buy status on the 1438426-1?

A: Last Time Buy status indicates that the 1438426-1 is no longer in active production. This designation signals the end of component availability from the manufacturer. The 1438426-3, which maintains Active status, is the recommended alternative for continued component sourcing.

Q: Are there differences in contact compatibility between these parts?

A: No. Both the 1438426-1 and 1438426-3 use identical female socket contact types with crimp termination. Contacts are not included with either housing and must be sourced separately. Contacts compatible with one housing are compatible with the other.

Q: Does the housing color difference affect electrical performance?

A: No. Housing color is a cosmetic variation only. The black (1438426-1) and gray (1438426-3) housings are constructed from the same polyamide nylon material and provide identical electrical insulation and mechanical protection.

Q: What does the 0.64 series designation indicate?

A: The 0.64 series designation identifies these connectors as part of the TE Connectivity AMP Connectors product line with specific dimensional and performance characteristics. Both the 1438426-1 and 1438426-3 belong to this same series, confirming their equivalence.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 1438426-1 and 1438426-3 carry ROHS3 Compliant certification, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating unlimited shelf life and no moisture sensitivity restrictions. This rating is identical for both the 1438426-1 and 1438426-3.

Q: Does packaging type affect the connector's performance or compatibility?

A: No. Packaging type (bulk versus other configurations) affects only storage, handling, and ordering logistics. It does not influence electrical performance, mechanical fit, or functional compatibility between the 1438426-1 and 1438426-3.
