Substitute Part Grouping Explanation

Substitution of the obsolete 521498-9 is based on strict electrical and mechanical parameter alignment. The substitute part 2-521498-9 maintains identical functional specifications across all critical parameters: terminal type (Quick Connect, Disconnect), gender (Female, Receptacle), terminal size (0.250" / 6.35mm), position count (4), stacking direction (Side to Side), mounting type (Panel Mount), color (Black), and material composition (Polyamide/Nylon).

The primary distinction between the main part and substitute is product status and packaging configuration. The 521498-9 is Obsolete with unspecified packaging, while 2-521498-9 is Active with Bulk packaging. Both parts share the same base product number (521498) and are manufactured by TE Connectivity AMP Connectors within the Faston series.

Substitution is valid when the following parameters are matched:

• Terminal Type: Quick Connect, Disconnect
• Gender: Female, Receptacle
• Terminal Size: 0.250" (6.35mm)
• Number of Positions: 4
• Mounting Type: Panel Mount
• Material: Polyamide (PA), Nylon

Parameter Comparison

Engineering Selection Recommendations

The 2-521498-9 is the direct substitute for the obsolete 521498-9. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 521498-9 is classified as Obsolete, making continued procurement impractical. The 2-521498-9 maintains Active product status, ensuring long-term availability and supply chain continuity.

Compliance Certifications: Both parts maintain equivalent environmental compliance. The 521498-9 is ROHS3 Compliant, while the 2-521498-9 is RoHS Compliant. Both parts carry EAR99 ECCN classification and share identical HTSUS coding (8538.90.6000), indicating regulatory equivalence for export and import purposes.

Moisture Sensitivity: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Functional Equivalence: All electrical and mechanical parameters are identical, confirming direct interchangeability in applications designed for the 521498-9.

Frequently Asked Questions (FAQ)

Q: Can 2-521498-9 be used as a direct replacement for 521498-9?

A: Yes. The 2-521498-9 is a direct substitute. All functional parameters—terminal type, gender, terminal size, position count, mounting type, material, and color—are identical. The primary difference is product status (Active vs. Obsolete) and packaging configuration (Bulk vs. unspecified).

Q: What is the difference between packaging types for these parts?

A: The 521498-9 has unspecified packaging, while the 2-521498-9 is supplied in Bulk packaging. Bulk packaging typically indicates standard industrial packaging without special protective measures. Selection between packaging types depends on inventory management and handling requirements for your application.

Q: Are there compliance differences between the two parts?

A: Both parts are environmentally compliant. The 521498-9 is ROHS3 Compliant, and the 2-521498-9 is RoHS Compliant. Both carry identical ECCN (EAR99) and HTSUS (8538.90.6000) classifications, confirming regulatory equivalence.

Q: What does the base product number 521498 indicate?

A: The base product number 521498 identifies the core connector housing design. Both the 521498-9 and 2-521498-9 share this base number, indicating they are variants of the same fundamental product within the Faston series.

Q: Are contacts included with these housing connectors?

A: No. Both parts are housings only. Contacts are not included and must be sourced separately for 0.250" (6.35mm) Quick Connect applications.

Q: What is the stacking direction, and why does it matter?

A: Both parts use Side to Side stacking direction, meaning multiple connectors stack horizontally. This parameter is critical for panel layout and space planning in applications requiring multiple connector positions.

Q: Can these parts be used in moisture-sensitive environments?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. These components can be stored and used in standard industrial environments without special moisture control measures.
