DRAR10HB Equivalent & Substitute Parts

Part Overview

The DRAR10HB is a rotary DIP switch manufactured by NKK Switches, designed for BCD circuit applications requiring 10-position selection at 100mA and 5VDC. This component features a panel-mount, right-angle configuration with a rotary shaft actuator and gold-plated copper contacts. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The FR01AR10HB-S qualifies as a substitute for the DRAR10HB based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Circuit type: BCD
• Number of positions: 10
• Current rating: 100mA
• Voltage rating: 5VDC
• Actuator type: Rotary with Shaft
• Mounting type: Panel Mount, Right Angle
• Termination style: PC Pin
• Pitch: 0.100" (2.54mm)
• Height above board: 0.433" (11.00mm)
• Contact finish: Gold

Differing Parameters:

• Operating temperature range: FR01AR10HB-S extends to 85°C (versus 75°C for DRAR10HB)
• Mechanical life: FR01AR10HB-S rated for 10,000 steps (versus 20,000 for DRAR10HB)
• Electrical life: FR01AR10HB-S rated for 10,000 steps (versus 20,000 for DRAR10HB)
• Body material: FR01AR10HB-S uses Polyamide (PA) Nylon, Glass Filled (versus Polybutylene Terephthalate for DRAR10HB)
• Contact material: FR01AR10HB-S uses Copper Alloy (versus Copper for DRAR10HB)
• Length: FR01AR10HB-S measures 0.516" (13.11mm) (versus 0.457" for DRAR10HB)
• Washable: FR01AR10HB-S is not washable (versus washable for DRAR10HB)
• RoHS Status: FR01AR10HB-S is ROHS3 Compliant (versus RoHS non-compliant for DRAR10HB)
• Product status: FR01AR10HB-S is Active

Parameter Comparison

Engineering Selection Recommendations

The FR01AR10HB-S is functionally compatible with the DRAR10HB for applications requiring BCD 10-position rotary DIP switches at 100mA and 5VDC with panel-mount, right-angle configuration. The substitute part maintains identical electrical and mechanical interface parameters, ensuring direct replacement capability in circuit design.

The FR01AR10HB-S offers the advantage of active product status and ROHS3 compliance, addressing regulatory requirements for new designs and long-term component availability. The extended operating temperature range to 85°C provides additional thermal margin for applications operating at elevated ambient conditions.

Applications requiring washability or the extended mechanical/electrical life rating of 20,000 steps should evaluate the performance requirements against the FR01AR10HB-S specification of 10,000 steps. The increased length of 0.516" (13.11mm) versus 0.457" (11.61mm) requires verification of available panel space in existing mechanical designs.

Frequently Asked Questions (FAQ)

Q: Can FR01AR10HB-S directly replace DRAR10HB in existing designs?

A: Yes. Both parts share identical electrical ratings (100mA, 5VDC), circuit type (BCD), position count (10), actuator configuration (rotary with shaft), mounting type (panel mount, right angle), termination style (PC pin), and pitch (0.100"). The interface and functional behavior are equivalent.

Q: What are the key differences between these parts?

A: The primary differences are product status (FR01AR10HB-S is active versus DRAR10HB obsolete), RoHS compliance (FR01AR10HB-S is ROHS3 compliant), operating temperature range (FR01AR10HB-S extends to 85°C), mechanical/electrical life (FR01AR10HB-S rated for 10,000 steps versus 20,000), and physical length (FR01AR10HB-S is 0.059" longer).

Q: Does the longer length of FR01AR10HB-S affect panel mounting?

A: The height above board remains identical at 0.433" (11.00mm). The increased length of 0.516" (13.11mm) versus 0.457" (11.61mm) affects the overall component footprint. Verify available panel space in mechanical designs before substitution.

Q: Is washability a concern for substitution?

A: The DRAR10HB is washable while FR01AR10HB-S is not. Applications requiring post-assembly cleaning must evaluate alternative solutions or confirm that FR01AR10HB-S meets process requirements.

Q: What is the impact of reduced mechanical and electrical life ratings?

A: FR01AR10HB-S is rated for 10,000 steps versus 20,000 steps for DRAR10HB. Applications with high cycle count requirements should assess whether the reduced life rating meets operational expectations over the product lifecycle.

Q: Are there packaging differences?

A: DRAR10HB uses standard packaging while FR01AR10HB-S is supplied in tube packaging. Verify packaging requirements for procurement and handling processes.
