Substitute Part Grouping Explanation

Substitution eligibility for the 1-521498-2 is determined by strict equivalence across the following critical parameters:

Terminal Type: Quick Connect, Disconnect functionality
Gender Configuration: Female, Receptacle orientation
Terminal Size: 0.250" (6.35mm) contact interface
Position Count: 4-position housing configuration
Stacking Geometry: Side to Side arrangement
Mounting Interface: Panel Mount installation method
Housing Material: Polyamide (PA) or Nylon composition
Series Designation: Faston connector family
Contact Inclusion: Contacts Not Included (housing only)

Parts meeting all these parameters are classified as direct substitutes. Variations in product status, packaging format, or compliance certifications do not affect functional interchangeability when all electrical and mechanical parameters align.

Engineering Selection Recommendations

The 2-521498-2 is a direct functional equivalent to the 1-521498-2 across all electrical and mechanical parameters. Both parts are manufactured by TE Connectivity AMP Connectors and share identical specifications for terminal type, gender, size, position count, mounting configuration, and material composition.

The primary distinction between these parts is product lifecycle status: the 1-521498-2 is classified as Obsolete, while the 2-521498-2 maintains Active status. Both parts maintain ROHS3 compliance and identical regulatory certifications (ECCN: EAR99, HTSUS: 8538.90.6000).

For new designs and ongoing production applications, the 2-521498-2 is the appropriate selection due to its Active product status and confirmed availability. For legacy system support or field replacement scenarios where original part specifications must be maintained, the 1-521498-2 remains functionally interchangeable with the 2-521498-2 when inventory permits.

Packaging differences (unspecified for 1-521498-2 versus Bulk for 2-521498-2) do not affect component functionality and reflect standard distribution practices.

Frequently Asked Questions (FAQ)

Q: Are the 1-521498-2 and 2-521498-2 electrically and mechanically interchangeable?

A: Yes. Both parts are identical across all functional parameters: terminal type, gender, size, position count, stacking direction, mounting type, material, and series designation. They are direct substitutes.

Q: Why does the 1-521498-2 show Obsolete status while the 2-521498-2 is Active?

A: Product status reflects the manufacturer's lifecycle classification. The 2-521498-2 represents the current active offering in the Faston series for this connector configuration. The 1-521498-2 remains functionally equivalent but is no longer the primary production part.

Q: What is the significance of the packaging difference between these parts?

A: The 1-521498-2 packaging is unspecified in available documentation, while the 2-521498-2 is supplied in Bulk packaging. Packaging format does not affect the connector's electrical or mechanical performance and is determined by distribution and procurement requirements.

Q: Do both parts require separate contact components?

A: Yes. Both the 1-521498-2 and 2-521498-2 are housing-only components. Contacts are not included and must be sourced separately for 0.250" (6.35mm) Quick Connect applications.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts maintain identical compliance certifications: ROHS3 Compliant, ECCN EAR99, and HTSUS 8538.90.6000. Moisture Sensitivity Level is 1 (Unlimited) for both parts.

Q: Can the 2-521498-2 be used as a direct replacement in existing assemblies designed for the 1-521498-2?

A: Yes. The 2-521498-2 is a direct functional replacement. All mounting interfaces, electrical connections, and mechanical dimensions are identical, enabling seamless substitution in existing designs.
