Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC60SA5-B is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NC (1 Form B) to maintain identical switching logic
• Output Type: Must be DC to match load switching requirements
• Load Voltage Range: Must encompass or equal 3V – 60V
• Load Current Rating: Must be equal to or greater than 5A
• Package Type: Must be hockey puck to ensure mechanical compatibility
• Termination Style: Must be screw terminal for connection compatibility
• Mounting Type: Must be chassis mount for installation compatibility

The DC60S7-B qualifies as a manufacturer-recommended substitute because it maintains all critical electrical and mechanical parameters while providing an increased load current rating of 7A, offering enhanced current capacity within the same form factor and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The DC60S7-B is the manufacturer-recommended substitute for the obsolete DC60SA5-B. Selection of this substitute is based on:

• Functional Equivalence: Both devices maintain identical SPST-NC circuit configuration, DC output type, and load voltage range (3V – 60V)
• Enhanced Current Capacity: The DC60S7-B provides 7A load current rating, exceeding the original 5A specification, ensuring compatibility with applications requiring up to 5A
• Product Status: The DC60S7-B holds active product status, ensuring ongoing availability and supply chain continuity
• Compliance: The DC60S7-B maintains ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Mechanical Compatibility: Identical hockey puck package, chassis mount configuration, and screw terminal termination ensure direct mechanical substitution

Critical Note: The input voltage specification differs between the two devices. The DC60SA5-B accepts 90 – 280VAC input, while the DC60S7-B accepts 4.6 – 32VDC input. Verification of input voltage compatibility with the application circuit is required before substitution.

Frequently Asked Questions (FAQ)

Q: Can the DC60S7-B directly replace the DC60SA5-B in all applications?

A: The DC60S7-B is mechanically and electrically compatible for load switching applications within the 3V – 60V range at currents up to 5A. However, the input voltage specification differs significantly. The original device accepts 90 – 280VAC input, while the substitute accepts 4.6 – 32VDC input. The application circuit must provide compatible input voltage to the substitute device.

Q: Why is the load current rating different between these devices?

A: The DC60S7-B is rated for 7A load current compared to the DC60SA5-B's 5A rating. This represents an enhanced current capacity within the same package and voltage specifications. Applications requiring 5A or less will operate within the safe operating range of the substitute.

Q: Are the package dimensions identical between DC60SA5-B and DC60S7-B?

A: Both devices use the hockey puck package type with chassis mount configuration and screw terminal termination. The mechanical form factor is identical, enabling direct physical substitution in existing mounting arrangements.

Q: What compliance certifications apply to the DC60S7-B?

A: The DC60S7-B is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Q: Is the DC60S7-B currently available?

A: Yes, the DC60S7-B maintains active product status with current inventory availability, ensuring reliable supply chain access compared to the obsolete DC60SA5-B.
