KSC523GR0HS Equivalent & Substitute Parts

Part Overview

The KSC523GR0HS is an active SPST-NO tactile switch manufactured by C&K, designed for surface mount applications with a contact rating of 0.01A at 32VDC. This component is part of the KSC5 series and is currently in active production status. Alternative models may be required due to inventory constraints, specific application voltage requirements, or packaging format preferences in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSC523GR0HS is determined by the following critical parameters:

Circuit Configuration: Both the main part and substitute must maintain SPST-NO (Single Pole Single Throw - Normally Open) topology to ensure functional equivalence in control applications.

Mounting Type: Surface mount compatibility is required. Both the main part and substitute use gull wing termination style suitable for automated assembly processes.

Physical Compatibility: Outline dimensions and actuator height must accommodate the same PCB footprint and clearance envelope. The main part measures 6.20mm x 6.20mm with 5.60mm actuator height.

Electrical Performance: Contact rating and voltage specifications determine application suitability. The main part is rated 0.01A @ 32VDC, establishing the minimum electrical capability threshold.

Environmental Compliance: RoHS3 compliance and REACH unaffected status are mandatory for equivalent substitution in regulated markets.

The substitute part 1301.9315.24 (SCHURTER Inc., LSH series) shares the same circuit configuration, mounting type, termination style, and compliance certifications. However, it operates at reduced voltage (12VDC) and current (0.05A) specifications, with different physical dimensions (6.00mm x 6.00mm) and actuator height (5.00mm).

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and ROHS3 compliance with REACH unaffected designation, establishing baseline regulatory equivalence.

The KSC523GR0HS operates across an extended temperature range (-40°C ~ 125°C) compared to the SCHURTER substitute (-20°C ~ 70°C). Applications requiring operation below -20°C or above 70°C must retain the C&K component.

The voltage rating differential (32VDC vs. 12VDC) is significant. The KSC523GR0HS is suitable for higher voltage applications. The SCHURTER part is restricted to 12VDC maximum operation and cannot substitute in circuits exceeding this voltage specification.

Physical dimensions differ slightly. The SCHURTER part is marginally smaller (6.00mm x 6.00mm vs. 6.20mm x 6.20mm) with lower actuator height (5.00mm vs. 5.60mm). PCB layout verification is required before substitution to confirm footprint compatibility and clearance adequacy.

The SCHURTER substitute offers extended mechanical life (100,000 cycles vs. 10,000 cycles) and lower operating force (160gf vs. 200gf), which may provide advantages in high-cycle applications with reduced actuation effort requirements.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 1301.9315.24 replace the C&K KSC523GR0HS in all applications?

A: No. The SCHURTER part is restricted to 12VDC maximum operation, while the C&K part is rated 32VDC. Substitution is only valid for applications operating at 12VDC or below. Additionally, the operating temperature range is narrower (-20°C ~ 70°C vs. -40°C ~ 125°C), limiting use in extreme temperature environments.

Q: What are the physical compatibility considerations?

A: Both parts use surface mount gull wing termination and similar outline dimensions (6.20mm x 6.20mm vs. 6.00mm x 6.00mm). The actuator height difference (5.60mm vs. 5.00mm) is minor but should be verified against PCB clearance requirements and enclosure constraints.

Q: Are there packaging differences between these parts?

A: Yes. The C&K KSC523GR0HS is supplied in Bulk packaging, while the SCHURTER 1301.9315.24 is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly compatibility.

Q: Which part has better mechanical durability?

A: The SCHURTER 1301.9315.24 is rated for 100,000 mechanical cycles compared to 10,000 cycles for the C&K part. For high-cycle applications, the SCHURTER component offers extended service life.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for restricted substance compliance.

Q: What is the operating force difference, and does it matter?

A: The C&K part requires 200gf operating force, while the SCHURTER part requires 160gf. The lower force requirement of the SCHURTER component may reduce user actuation effort but should be evaluated against application ergonomic and tactile feedback requirements.
