Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2-6437630-9 is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Current Rating: 6A (AC) minimum
• Voltage Rating - AC: 125V minimum
• Switch Function: On-On operation

Mechanical Compatibility Parameters:

• Mounting Type: Panel Mount, Snap-In
• Panel Cutout Dimensions: Rectangular - 15.90mm x 13.00mm
• Termination Style: Solder Lug

Regulatory & Certification Parameters:

• Approval Agencies: CSA, UL certification required
• ECCN: EAR99
• HTSUS: 8536.50.9065

The substitute part 2-6437630-6 shares identical electrical ratings, mechanical mounting specifications, panel cutout dimensions, termination style, and regulatory certifications. The primary difference lies in circuit configuration (DPDT versus SPDT) and series designation (FLN versus FLD), which represents a functional variation rather than a direct one-to-one replacement. This substitution is valid only when the application circuit design accommodates DPDT functionality.

Parameter Comparison

Engineering Selection Recommendations

The 2-6437630-9 is classified as Obsolete. The substitute part 2-6437630-6 is classified as Active and maintains current manufacturing status with TE Connectivity ALCOSWITCH Switches.

Selection Criteria Based on Product Status and Compliance:

The 2-6437630-6 is suitable as a substitute when the following conditions are met:

1. Circuit Design Accommodation: The application circuit must support DPDT (Double Pole Double Throw) functionality. The 2-6437630-6 provides two independent switching poles compared to the single pole of the 2-6437630-9. Circuit redesign may be required to utilize both poles or to disable one pole through design methodology.

2. Regulatory Compliance: Both parts carry identical CSA and UL certifications, meeting the same regulatory approval requirements. Both parts are classified under ECCN EAR99 and HTSUS 8536.50.9065.

3. Mechanical Integration: Both parts feature identical panel mount snap-in installation and rectangular cutout dimensions (15.90mm x 13.00mm), ensuring direct mechanical compatibility in existing panel designs.

4. Electrical Performance: Both parts are rated for 6A AC at 125V with identical mechanical life (100,000 cycles) and electrical life (50,000 cycles), providing equivalent electrical performance within the specified operating envelope.

5. Supply Chain Continuity: The 2-6437630-6 is currently in active production status with 921 pieces available in inventory, compared to the obsolete status of the 2-6437630-9 with 827 pieces remaining in stock.

Frequently Asked Questions (FAQ)

Q: Can the 2-6437630-6 be used as a direct replacement for the 2-6437630-9 without circuit modification?

A: Direct replacement without circuit modification is not possible. The 2-6437630-6 is a DPDT switch, while the 2-6437630-9 is SPDT. The circuit design must accommodate the additional pole provided by the DPDT configuration. Unused poles can be left unconnected if the application design permits, but this must be evaluated on a case-by-case basis.

Q: Are the panel cutout dimensions identical between these two parts?

A: Yes. Both the 2-6437630-9 and 2-6437630-6 require an identical rectangular panel cutout of 15.90mm x 13.00mm. No mechanical modification to the panel is required for substitution.

Q: Do both parts meet the same regulatory certifications?

A: Yes. Both parts carry CSA and UL approvals and are classified under the same ECCN (EAR99) and HTSUS (8536.50.9065) codes.

Q: What is the difference in actuator design between these parts?

A: The 2-6437630-9 features a concave standard V actuator in black, while the 2-6437630-6 features a paddle actuator in white. These are cosmetic and ergonomic differences that do not affect electrical or mechanical compatibility.

Q: What is the operational life difference between these switches?

A: Both parts are rated for 100,000 mechanical cycles and 50,000 electrical cycles. There is no difference in operational life specifications.

Q: Why is the 2-6437630-9 classified as Obsolete?

A: The 2-6437630-9 is no longer in active production by TE Connectivity ALCOSWITCH Switches. The 2-6437630-6 represents the current active product line for this switch category.

Q: Can I use the 2-6437630-6 in applications requiring lower current or voltage ratings?

A: The 2-6437630-6 is rated for 6A AC at 125V. It can be used in applications requiring lower current or voltage within this envelope. The part is not suitable for applications exceeding these ratings.

Q: Are there packaging differences between the main part and substitute?

A: The 2-6437630-9 is listed with packaging designation "-" (not specified), while the 2-6437630-6 is packaged in Bulk. This represents a packaging format difference that may affect procurement and inventory management but does not impact functional compatibility.
