Substitute Part Grouping Explanation

Substitution of the 2066502-2 is based on electrical and mechanical parameter alignment. The substitute part 1-2066502-2 maintains equivalence through the following critical parameters:

• Current Rating: Both parts rated at 25 A
• Fuse Type and Size: Both accommodate blade-type miniature (ATM) fuses measuring 0.433" L x 0.152" W (11.00mm x 3.85mm)
• Circuit Configuration: Both provide 2-circuit capacity
• Orientation Capability: Both support horizontal and vertical mounting orientations
• Termination Interface: Both utilize Quick Connect termination at 0.110" (2.8mm)
• Base Product Number: Both share base product number 2066502, indicating common design lineage

The substitute part differs in mounting type specification and product status, with the substitute classified as active and available in higher inventory quantities.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-2066502-2 is the direct equivalent for the obsolete 2066502-2. Selection of the substitute is supported by the following factors:

Product Status: The substitute part maintains active product status with TE Connectivity Deutsch Connectors, ensuring continued availability and manufacturing support. The main part is classified as obsolete, limiting future procurement options.

Compliance Certification: The substitute part carries ROHS3 compliance, representing current regulatory standards. The main part carries RoHS compliance, indicating an earlier compliance designation.

Electrical and Mechanical Compatibility: Both parts share identical current ratings, fuse type specifications, fuse dimensions, circuit configuration, orientation capabilities, and termination interface specifications. These parameters ensure direct functional equivalence in circuit protection applications.

Inventory Availability: The substitute part is available in higher quantities (1117 Pcs) compared to the main part (763 Pcs), providing improved supply chain reliability.

Manufacturing Lineage: Both parts share the same base product number (2066502), confirming common design heritage and engineering validation.

Frequently Asked Questions (FAQ)

Q: Can the 1-2066502-2 substitute directly replace the 2066502-2 in existing applications?

A: Yes. Both parts maintain identical electrical ratings (25 A), fuse type specifications (blade miniature ATM), fuse dimensions (0.433" L x 0.152" W), circuit configuration (2-circuit), orientation capability (horizontal and vertical), and termination interface (Quick Connect 0.110"). These parameters define functional equivalence for fuse holder applications.

Q: What is the difference between the main part and the substitute?

A: The primary differences are product status and compliance designation. The 2066502-2 is classified as obsolete with RoHS compliance, while the 1-2066502-2 is active with ROHS3 compliance. The substitute also specifies bulk packaging and does not list a specific mounting type designation, though orientation capability remains identical.

Q: Are there packaging differences between these parts?

A: The main part specifies packaging as "-" (not provided), while the substitute specifies bulk packaging. Packaging configuration does not affect electrical or mechanical compatibility for fuse holder applications.

Q: Why should I transition from the 2066502-2 to the 1-2066502-2?

A: The 2066502-2 is obsolete, which limits future procurement availability. The 1-2066502-2 is an active product with higher inventory levels and current compliance certifications, ensuring long-term supply chain continuity and regulatory alignment.

Q: Do both parts accommodate the same fuse specifications?

A: Yes. Both parts are designed for miniature (ATM) blade fuses measuring 0.433" L x 0.152" W (11.00mm x 3.85mm) and both support 25 A current ratings. Fuse compatibility is identical.

Q: What is the significance of the shared base product number?

A: The shared base product number 2066502 indicates that both parts derive from the same product design platform. This confirms engineering validation and design compatibility between the main part and substitute.
