Substitute Part Grouping Explanation

Substitution of the Molex 0008580121 is determined by the following critical parameters:

• Wire gauge compatibility: 18-24 AWG
• Contact termination method: Crimp
• Contact finish material: Gold
• Electrical connector category: Rectangular Connectors
• Compliance certifications: ROHS3 Compliant, EAR99 ECCN classification

The TE Connectivity AMP Connectors part 770258-1 qualifies as a substitute based on matching wire gauge, crimp termination, gold contact finish, and equivalent compliance certifications. Differences in contact configuration (socket vs. non-gendered) and series designation reflect design variations within the rectangular connector category that do not preclude functional substitution in applications requiring these core electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0008580121 and TE Connectivity 770258-1 are Active products with ROHS3 compliance and identical ECCN/HTSUS classifications. Selection between these parts should be based on:

• Connector system compatibility requirements (KK 2478 series vs. SL-156 series)
• Packaging format preference (Cut Tape vs. Bulk)
• Current inventory availability and lead time
• Contact configuration requirements (non-gendered vs. socket)
• Established supplier relationships and procurement procedures

Both parts meet the core electrical and regulatory requirements for 18-24 AWG crimp-terminated gold-plated rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 770258-1 directly replace the Molex 0008580121 in all applications?

A: Substitution is valid when the application requires 18-24 AWG crimp termination with gold contact finish. However, connector system compatibility must be verified, as the parts belong to different series (KK 2478 vs. SL-156). Mechanical fit within the connector housing must be confirmed before implementation.

Q: What is the significance of the contact configuration difference (non-gendered vs. socket)?

A: Contact configuration determines mating compatibility within a connector system. The Molex part is non-gendered, while the TE Connectivity part is socket-configured. This difference affects how the contact interfaces with complementary pin or socket contacts in the assembled connector. System design must accommodate this distinction.

Q: Are there packaging considerations when switching between these parts?

A: Yes. The Molex 0008580121 is supplied in Cut Tape (CT) packaging, while the TE Connectivity 770258-1 is supplied in Bulk packaging. This affects handling, storage, and automated assembly processes. Procurement and manufacturing workflows may require adjustment.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are ROHS3 Compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8536.90.4000). Both have MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Compliance profiles are equivalent.

Q: What wire gauges are supported by these connector contacts?

A: Both the Molex 0008580121 and TE Connectivity 770258-1 support 18-24 AWG wire gauge range. This range accommodates standard industrial and commercial wiring applications within the specified gauge parameters.
