DRKC10H Equivalent & Substitute Parts

Part Overview

The DRKC10H is a 10-position rotary DIP switch manufactured by NKK Switches, designed for BCD complement circuit applications. This component features a rotary shaft actuator, through-hole right-angle mounting, and is rated for 100mA at 5VDC. The DRKC10H is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DRKC10H are identified based on the following critical parameters that determine functional equivalence:

• Circuit configuration: BCD Complement (10-position)
• Electrical ratings: 100mA at 5VDC
• Mechanical interface: Rotary shaft actuator, through-hole right-angle mounting
• Pitch and height: 0.100" (2.54mm) pitch, 0.394" (10.00mm) height above board
• Termination: PC pin configuration
• Contact system: Gold-finished copper or copper alloy contacts

The substitute parts FR01KC10H-S and FR01KC10H-06XL-S meet these core functional requirements. Both are active products from NKK Switches with identical electrical specifications and mechanical compatibility. Variations in body material, mechanical life ratings, and operating temperature range represent design improvements in the FR01 series while maintaining pin-for-pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both FR01KC10H-S and FR01KC10H-06XL-S are suitable replacements for the obsolete DRKC10H based on electrical and mechanical compatibility. Selection between these two active alternatives should consider the following factors:

FR01KC10H-S is the standard configuration with tube packaging and represents the primary substitute for direct replacement applications.

FR01KC10H-06XL-S is supplied in tube packaging with extended lead length designation (06XL), providing additional flexibility for specific board layout requirements.

Both substitute parts are ROHS3 compliant and carry REACH unaffected status, meeting current regulatory requirements. The extended operating temperature range of -25°C to 85°C in the FR01 series provides improved thermal margin compared to the DRKC10H specification of -25°C to 75°C.

The reduced mechanical and electrical life ratings (10,000 steps versus 20,000 steps) in the FR01 series reflect design optimization in the active product line. For applications requiring the original 20,000-step specification, this parameter difference must be evaluated against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Are FR01KC10H-S and FR01KC10H-06XL-S pin-for-pin compatible with DRKC10H?

A: Yes. Both substitute parts maintain identical pitch (0.100" / 2.54mm), height above board (0.394" / 10.00mm), and PC pin termination configuration. Through-hole right-angle mounting is preserved across all three part numbers.

Q: What is the difference between FR01KC10H-S and FR01KC10H-06XL-S?

A: Both parts are functionally identical in electrical and mechanical specifications. The 06XL designation indicates extended lead length, which may be relevant for specific PCB layout or assembly requirements. Consult the detailed mechanical drawings for lead length specifications.

Q: Can I use FR01KC10H-S or FR01KC10H-06XL-S in place of DRKC10H in existing designs?

A: Yes, for applications where the 10,000-step mechanical and electrical life rating is acceptable. The extended operating temperature range (-25°C to 85°C) and ROHS3 compliance of the FR01 series provide design advantages. Verify that your application does not require the original 20,000-step life specification.

Q: What is the significance of the extended operating temperature range in the FR01 series?

A: The FR01KC10H-S and FR01KC10H-06XL-S operate to 85°C versus 75°C for the DRKC10H. This 10°C margin provides additional thermal headroom for applications operating in elevated ambient conditions or with internal heat generation.

Q: Are there packaging differences between these parts?

A: DRKC10H is supplied with standard packaging. FR01KC10H-S and FR01KC10H-06XL-S are supplied in tube packaging. Verify tube packaging compatibility with your assembly process and handling requirements.

Q: What compliance certifications apply to the substitute parts?

A: Both FR01KC10H-S and FR01KC10H-06XL-S are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for all three parts. HTSUS code 8536.50.9065 applies uniformly across the product group.
