SDB07H0SBD Equivalent & Substitute Parts

Part Overview

The SDB07H0SBD is a DIP 7-position surface mount slide switch manufactured by C&K, designed for 25mA 24VDC applications with flush, recessed actuator operation. This component features gold-plated phosphor bronze contacts and is rated for 1,000 mechanical and electrical cycles. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDB07H0SBD is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST (Single Pole Single Throw)
• Position count: 7 positions
• Electrical ratings: 25mA at 24VDC
• Actuator mechanism: Slide (Standard) with flush, recessed actuation
• Mounting configuration: Surface mount with gull wing termination
• Pitch spacing: 0.100" (2.54mm) full pitch
• Environmental compliance: ROHS3 Compliant
• Operating temperature range: -40°C ~ 85°C

The SDA07H0SBD qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in contact material (beryllium copper vs. phosphor bronze), body material (polyphenylene sulfide vs. polyamide), and height above board (0.175" vs. 0.157") do not affect functional compatibility within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The SDA07H0SBD is the appropriate substitute for the obsolete SDB07H0SBD. Both components are manufactured by C&K and maintain identical electrical specifications (SPST, 7-position, 25mA, 24VDC) with equivalent mechanical interfaces (surface mount, gull wing termination, 0.100" pitch). The SDA07H0SBD carries active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting current regulatory requirements. The minor dimensional variation in height above board (0.175" vs. 0.157") is within typical PCB layout tolerances for surface mount applications and does not compromise functional performance or thermal management.

Frequently Asked Questions (FAQ)

Q: Can the SDA07H0SBD be used as a direct replacement for the SDB07H0SBD in existing designs?

A: Yes. Both components share identical electrical ratings (25mA, 24VDC, SPST, 7-position), actuator type (slide standard), and mechanical interface (surface mount, gull wing, 0.100" pitch). The height difference of 0.018" (0.45mm) is negligible for standard PCB layouts.

Q: What is the primary reason for substitution?

A: The SDB07H0SBD is obsolete. The SDA07H0SBD is an active product from the same manufacturer with equivalent electrical and mechanical specifications, ensuring long-term availability and supply continuity.

Q: Are there differences in contact material between these parts?

A: Yes. The SDB07H0SBD uses phosphor bronze contacts, while the SDA07H0SBD uses beryllium copper contacts. Both are gold-plated and rated for identical electrical performance (25mA, 24VDC, 1,000 cycles). Contact material differences do not affect functional compatibility within specified operating parameters.

Q: Do both parts meet current compliance standards?

A: Yes. Both the SDB07H0SBD and SDA07H0SBD are ROHS3 compliant. The SDA07H0SBD additionally carries REACH Unaffected status, confirming compliance with current environmental regulations.

Q: What packaging is available for the SDA07H0SBD?

A: The SDA07H0SBD is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are there any thermal or environmental limitations when substituting?

A: No. Both components operate across the identical temperature range (-40°C ~ 85°C) and maintain MSL 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements.
