Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GT12MSCKETR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST only
• Switch function: On-Off operation
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC minimum
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Actuator type and length: Standard Round, 3.81mm
• Operating temperature range: -30°C to 85°C minimum
• Electrical life: 40,000 cycles minimum

The GT12MSCBE qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and functional characteristics across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The GT12MSCBE is the qualified substitute for the obsolete GT12MSCKETR. Both components share identical electrical and mechanical specifications, ensuring direct functional equivalence in circuit applications.

The GT12MSCBE offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The substitute component is ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing processes. The REACH Affected designation indicates compliance with chemical substance regulations.

Packaging differs between the two parts: the main part is supplied in bulk format, while the substitute is available in Tape & Reel (TR) configuration, which is standard for automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can GT12MSCBE be used as a direct replacement for GT12MSCKETR in existing designs?

A: Yes. Both components are electrically and mechanically identical across all critical parameters: SPST circuit, 0.4VA at 20V rating, surface mount gull wing termination, and 3.81mm standard round actuator. The substitute maintains the same operating temperature range and electrical life specifications.

Q: What is the primary reason to transition from GT12MSCKETR to GT12MSCBE?

A: The GT12MSCKETR is obsolete, while GT12MSCBE is an active product with confirmed ongoing availability. This ensures supply chain continuity and access to current manufacturing batches.

Q: Are there compliance differences between these parts?

A: Yes. The GT12MSCBE is ROHS3 compliant and REACH Affected, meeting current environmental and chemical substance regulations. The GT12MSCKETR is RoHS non-compliant and REACH Unaffected. For new designs or manufacturing processes subject to these regulations, GT12MSCBE is the appropriate selection.

Q: Does packaging affect electrical or mechanical performance?

A: No. Packaging format (bulk versus Tape & Reel) does not affect component performance. The difference is operational: Tape & Reel packaging is optimized for automated assembly, while bulk packaging is suitable for manual or lower-volume applications.

Q: Are the actuator specifications identical?

A: Yes. Both components feature a standard round polyamide actuator with 3.81mm length, ensuring identical mechanical interface and user interaction characteristics.

Q: What is the electrical life rating for both components?

A: Both GT12MSCKETR and GT12MSCBE are rated for 40,000 switching cycles, providing equivalent operational durability.
