Substitute Part Grouping Explanation

The DB3C-B1RC qualifies as a direct substitute for the E63-30K based on the following critical parameters:

Matching Electrical Characteristics:

• Circuit configuration: Both are SPDT
• Switch function: Both are On-Momentary
• AC voltage rating: Both rated at 125V
• AC current rating: Both rated at 100mA
• Actuator type: Both feature lever/roller actuation
• Mounting configuration: Both are chassis mount
• Termination style: Both use Quick Connect - 0.110" (2.8mm) terminals

Compliance Alignment:

• Both components are ROHS3 compliant
• Both carry ECCN EAR99 classification
• Both share identical HTSUS code: 8536.50.7000
• Both have MSL rating of 1 (Unlimited)

The DB3C-B1RC represents an active product from the same manufacturer, providing enhanced reliability metrics and extended operational temperature range compared to the obsolete E63-30K.

Parameter Comparison

Engineering Selection Recommendations

The DB3C-B1RC is the appropriate substitute for the obsolete E63-30K in applications requiring SPDT snap-action switching at 125V AC and 100mA. Both components maintain identical electrical ratings and termination specifications, ensuring direct functional compatibility.

The DB3C-B1RC offers enhanced reliability through extended electrical life (100,000 cycles versus 6,000 cycles) and mechanical life specification (15,000,000 cycles). The expanded operating temperature range (-40°C to 120°C versus -40°C to 85°C) provides additional thermal margin for demanding environments. IP50 ingress protection on the DB3C-B1RC offers improved environmental sealing compared to the unspecified protection rating of the E63-30K.

Both components maintain identical RoHS3 compliance and regulatory classifications, supporting seamless integration into existing procurement and quality systems.

Frequently Asked Questions (FAQ)

Q: Can the DB3C-B1RC directly replace the E63-30K without circuit modification?

A: Yes. Both components share identical SPDT circuit configuration, On-Momentary function, 125V AC rating, 100mA AC current rating, lever/roller actuation, chassis mount configuration, and Quick Connect - 0.110" (2.8mm) termination. No circuit redesign is required.

Q: What are the key differences between these components?

A: The DB3C-B1RC is an active product with enhanced performance specifications. It provides 100,000 electrical cycles versus 6,000 cycles, includes mechanical life rating of 15,000,000 cycles, operates across -40°C to 120°C versus -40°C to 85°C, and includes IP50 dust protection. These represent improvements over the obsolete E63-30K.

Q: Are there packaging considerations for substitution?

A: The E63-30K is specified with dash packaging, while the DB3C-B1RC is supplied in bulk packaging. Verify that bulk packaging meets your procurement and handling requirements.

Q: Do both components meet the same compliance standards?

A: Yes. Both the E63-30K and DB3C-B1RC are ROHS3 compliant, carry ECCN EAR99 classification, share HTSUS code 8536.50.7000, and have MSL rating of 1 (Unlimited). Compliance documentation requirements remain consistent.

Q: What is the DC voltage rating difference?

A: The E63-30K is rated for 250mA DC at 30V. The DB3C-B1RC specifies only AC current rating (100mA). Verify DC voltage and current requirements for your specific application before substitution if DC operation is required.
