The substitute parts identified—Molex 0026202081 and Samtec Inc. FWJ-08-01-T-S—satisfy all primary compatibility criteria and maintain electrical performance within specified operating parameters. Both substitute parts are active products with current inventory availability and comply with applicable regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 640384-8 (Primary Part)

The TE Connectivity 640384-8 is an active product with established supply chain presence. This connector meets UL94 V-0 flammability requirements and operates across the full -55°C to 105°C temperature range. RoHS compliance and unlimited moisture sensitivity classification support deployment in general purpose and industrial applications. Selection of this part is appropriate when TE Connectivity supply chain preference or existing design validation exists.

Molex 0026202081 (Substitute Part)

The Molex 0026202081 provides functional equivalence across all primary compatibility parameters. This part features higher inventory availability (1574 units) and ROHS3 compliance. The material flammability rating is UL94 V-2, which differs from the primary part's UL94 V-0 specification. Operating temperature and voltage ratings are not specified in available documentation. Selection of this part is appropriate when inventory availability is prioritized and application requirements do not mandate UL94 V-0 flammability classification.

Samtec Inc. FWJ-08-01-T-S (Substitute Part)

The Samtec Inc. FWJ-08-01-T-S maintains full compatibility across all primary parameters and matches the primary part's UL94 V-0 flammability rating and -55°C to 105°C operating temperature range. This connector features enhanced voltage rating specifications (600VAC, 845VDC) and ROHS3 compliance. The contact shape is square rather than circular. Selection of this part is appropriate when flammability and temperature specifications must match the primary part exactly, or when enhanced voltage rating capability is required.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026202081 be used as a direct replacement for the TE Connectivity 640384-8?

A: The Molex 0026202081 satisfies all primary electrical and mechanical compatibility criteria, including connector type, contact type, position count, pitch, mounting method, and termination. However, the material flammability rating differs (UL94 V-2 versus UL94 V-0). Applications requiring UL94 V-0 certification must not substitute this part. Operating temperature and voltage ratings are not specified for the Molex part; verification against application requirements is necessary.

Q: What are the key differences between the Samtec FWJ-08-01-T-S and the TE Connectivity 640384-8?

A: Both parts share identical primary compatibility parameters and operating temperature range (-55°C to 105°C). The Samtec part features a square contact shape instead of circular, enhanced voltage rating (845VDC capability), and matching UL94 V-0 flammability classification. These differences do not affect functional interchangeability in standard applications.

Q: Are all three connectors RoHS compliant?

A: Yes. The TE Connectivity 640384-8 is RoHS Compliant. Both substitute parts—Molex 0026202081 and Samtec FWJ-08-01-T-S—are ROHS3 Compliant. All three parts meet applicable RoHS regulatory requirements.

Q: What is the significance of the 0.156" (3.96mm) pitch specification?

A: The 0.156" (3.96mm) pitch defines the center-to-center spacing between adjacent contact positions. This parameter is critical for mechanical interchangeability. All three parts maintain this identical pitch, ensuring that mating connectors and printed circuit board layouts remain compatible across substitutions.

Q: Can these connectors be used in automotive applications?

A: The TE Connectivity 640384-8 is classified for general purpose and industrial applications. The Molex 0026202081 is rated for automotive, general purpose, industrial, medical, and telecommunications applications. The Samtec FWJ-08-01-T-S does not specify application categories. Automotive application requirements must be evaluated against individual part certifications and design validation.

Q: What is the difference between contact length specifications?

A: The TE Connectivity 640384-8 specifies contact length - mating of 0.400" (10.16mm) and contact length - post of 0.125" (3.18mm), for an overall contact length of 0.650" (16.51mm). Both substitute parts feature contact length - mating of 0.450" (11.43mm) and contact length - post of 0.175" (4.45mm), for an overall contact length of 0.750" (19.05mm). These dimensional differences may affect board layout and mating depth; physical verification is required for applications with space constraints.

Q: Are all parts available in bulk packaging?

A: Yes. All three parts—TE Connectivity 640384-8, Molex 0026202081, and Samtec FWJ-08-01-T-S—are supplied in bulk packaging with current inventory availability.
