Parameter Comparison

Engineering Selection Recommendations

The 78B06RAT is the appropriate substitute for the obsolete 78C06RAT in new designs and production transitions. Selection is based on:

Product Status: The 78B06RAT maintains Active status with ongoing manufacturer support, whereas the 78C06RAT is classified as Obsolete and subject to discontinuation.

Regulatory Compliance: Both parts maintain RoHS compliance. The 78B06RAT achieves ROHS3 Compliant status, representing current regulatory alignment. Both parts are REACH Unaffected and classified under ECCN EAR99.

Electrical Performance: The 78B06RAT accommodates higher current (150mA versus 25mA) and voltage (30VDC versus 24VDC) specifications, providing design margin for applications within the original 78C06RAT's electrical envelope. Extended electrical life (10,000 cycles versus 2,000 cycles) supports higher-cycle applications.

Physical Compatibility: Identical pitch spacing (0.100"), mounting configuration (Through Hole, Right Angle), and actuator type (Slide Standard) ensure direct PCB footprint compatibility. Height variance (0.380" versus 0.390") is negligible for standard applications.

Temperature Range: The 78B06RAT extends operating temperature range to -40°C ~ 85°C, compared to -20°C ~ 70°C, supporting broader environmental applications.

Frequently Asked Questions (FAQ)

Q: Can the 78B06RAT directly replace the 78C06RAT on existing PCBs?

A: Yes. Both parts share identical pitch spacing (0.100"), through-hole right-angle mounting configuration, and 6-position SPST circuit topology. Height difference (0.010") is within standard PCB clearance tolerances.

Q: What are the key electrical differences between these parts?

A: The 78B06RAT provides 150mA current rating versus 25mA, and 30VDC voltage rating versus 24VDC. Electrical life extends to 10,000 cycles compared to 2,000 cycles. These enhancements support a broader range of circuit applications while maintaining backward compatibility for lower-power designs.

Q: Why is the 78C06RAT classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 78B06RAT represents the active equivalent within Grayhill's current product portfolio.

Q: Are there packaging differences?

A: The 78C06RAT is supplied in bulk packaging, while the 78B06RAT is supplied in tube packaging. Both are suitable for standard component handling and assembly processes.

Q: Do both parts meet current RoHS requirements?

A: Yes. The 78C06RAT is RoHS Compliant, and the 78B06RAT is ROHS3 Compliant, representing alignment with current regulatory standards. Both are REACH Unaffected.

Q: What is the mechanical life specification for both parts?

A: Both the 78C06RAT and 78B06RAT are rated for 2,000 mechanical cycles. The 78B06RAT provides extended electrical life at 10,000 cycles.

Q: Are contact materials equivalent?

A: The 78C06RAT uses phosphor bronze contacts, while the 78B06RAT uses copper alloy contacts. Both are gold-plated and suitable for standard switching applications. Contact material selection does not affect substitution compatibility for the specified electrical parameters.

Q: What is the operating temperature range for each part?

A: The 78C06RAT operates from -20°C to 70°C. The 78B06RAT extends this range to -40°C to 85°C, supporting applications requiring broader temperature performance.
