Key Parameters

Substitute Part Grouping Explanation

The C&K 7108SD9AV2BE qualifies as a direct substitute for the 7108SD9AV2BES based on the following critical parameters:

Matching Electrical Specifications:

• SPDT circuit configuration
• 0.4VA current rating (AC/DC)
• 20V AC and DC voltage ratings
• On-Mom switch function
• 40,000 cycle electrical life

Matching Mechanical Specifications:

• Through hole, right-angle, vertical mounting
• Standard round actuator type
• 12.45mm actuator length
• PC pin termination style
• Brass, chrome-plated actuator material

Matching Environmental & Compliance:

• Operating temperature range: -30°C to 85°C
• ROHS3 compliance
• MSL 1 (Unlimited)
• REACH affected status
• EAR99 ECCN classification

The primary difference is product status: the 7108SD9AV2BES is obsolete, while the 7108SD9AV2BE is active. The substitute maintains identical electrical and mechanical performance characteristics required for direct replacement in applications.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7108SD9AV2BE is the appropriate substitute for the obsolete 7108SD9AV2BES. Both parts maintain identical electrical performance, mechanical form factor, and environmental operating specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts carry ROHS3 compliance and REACH affected designation, meeting current regulatory requirements for electronic component procurement. The MSL 1 rating indicates no moisture sensitivity constraints during storage and handling.

Selection of the 7108SD9AV2BE eliminates obsolescence risk while preserving full functional compatibility with existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 7108SD9AV2BE directly replace the 7108SD9AV2BES in existing designs?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), switch function (On-Mom), and mechanical specifications (through-hole, right-angle mounting with 12.45mm actuator). No circuit modifications or PCB redesign is required.

Q: What is the primary reason for substitution?

A: The 7108SD9AV2BES is classified as obsolete. The 7108SD9AV2BE is the active equivalent from the same manufacturer and series, ensuring continued availability and supply chain support.

Q: Are there packaging differences between these parts?

A: Yes. The 7108SD9AV2BES is supplied in bulk packaging, while the 7108SD9AV2BE is supplied in tray packaging. This difference does not affect electrical or mechanical performance and is a standard variation in component distribution formats.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH affected, and carry EAR99 ECCN classification. Both maintain MSL 1 rating with unlimited moisture sensitivity constraints.

Q: What is the electrical life specification for these switches?

A: Both parts are rated for 40,000 cycles of electrical operation under the specified load conditions (0.4VA at 20V AC/DC).

Q: Are there any differences in actuator material or finish?

A: No. Both parts feature brass actuators with chrome plating and satin chrome finish, providing identical tactile and aesthetic characteristics.
