Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for SSR relays is determined by compatibility across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must support AC with zero-cross detection for synchronized switching
• Input Voltage Range: Must accommodate 18 ~ 36VAC control signal
• Package and Mounting: Must use hockey puck form factor with chassis mount capability
• Termination: Must use screw terminal interface for direct connection compatibility
• Load Voltage and Current Ratings: Substitute must meet or exceed the load requirements

The identified substitute part 84137012N meets these core substitution criteria within the allowed parameter envelope for this SSR category.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part 84137102 and substitute 84137012N are active production components with full RoHS compliance. The 84137012N provides higher load current capacity (25 A versus 10 A) but operates within a reduced load voltage range (24 V ~ 280 V versus 48 V ~ 660 V). Selection between these parts depends on the specific load voltage and current requirements of the application. Both components maintain identical control signal compatibility (18 ~ 36VAC input) and identical mechanical interfaces (hockey puck package, chassis mount, screw terminals).

Frequently Asked Questions (FAQ)

Q: Can the 84137012N substitute for the 84137102 in all applications?

A: Substitution is valid only when the application load voltage remains within the 24 V ~ 280 V range. Applications requiring load voltages above 280 V or below 24 V must use the 84137102 or equivalent parts rated for the full 48 V ~ 660 V range.

Q: What is the significance of the zero-cross output type?

A: Zero-cross detection ensures the SSR switches only when the AC voltage waveform crosses zero, reducing electromagnetic interference and extending component life. Both parts include this feature.

Q: Are the physical packages identical?

A: Yes. Both parts use the hockey puck form factor with chassis mount configuration and screw terminal termination, ensuring mechanical interchangeability in the same mounting location.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 84137102 and 84137012N are RoHS compliant and carry active product status, meeting current regulatory requirements.

Q: What is the primary difference between these two parts?

A: The 84137012N offers higher load current capacity (25 A) but with a narrower load voltage operating range (24 V ~ 280 V). The 84137102 provides lower current capacity (10 A) but supports a wider voltage range (48 V ~ 660 V).
