AHF11 Equivalent & Substitute Parts

Part Overview

The AHF11 is a tilt motion sensor manufactured by Panasonic Electric Works, designed for applications requiring angular detection within the 25° to 60° operating range. This through-hole, vertically-mounted sensor operates across a supply voltage range of 5V to 30V with a maximum output current of 100mA. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AHF11 is determined by the following critical parameters:

• Operating Angle Range: Must match or encompass 25° ~ 60°
• Mounting Type: Through-hole configuration required; orientation (vertical vs. horizontal) affects PCB layout compatibility
• Package / Case: PCB Mount form factor
• Voltage Supply Range: Must accommodate 5V ~ 30V operation
• Current Output Capacity: Must support 100mA output requirement
• Environmental Compliance: REACH and ECCN classifications must align with regulatory requirements

The AHF22 qualifies as a substitute based on matching operating angle (25° ~ 60°), through-hole PCB mount configuration, and equivalent regulatory compliance. The primary distinction is the horizontal mounting orientation of the AHF22 versus the vertical orientation of the AHF11, which affects circuit board placement but does not compromise functional substitution when layout permits reorientation.

Parameter Comparison

Engineering Selection Recommendations

The AHF22 is the designated substitute for the obsolete AHF11 based on functional parameter alignment and active product status. Both components share identical operating angle specifications (25° ~ 60°), PCB mount packaging, and regulatory compliance classifications. The AHF22 benefits from active manufacturing status, ensuring supply chain availability and consistency.

The primary design consideration is the orientation difference: the AHF11 features vertical mounting while the AHF22 is horizontally mounted. This distinction requires PCB layout evaluation to confirm spatial compatibility. Applications operating within the AHF22 temperature range (-20°C ~ 80°C) will experience no thermal limitations. Applications requiring the full -25°C lower temperature specification of the AHF11 must evaluate whether the AHF22's -20°C minimum is acceptable for the intended operating environment.

Frequently Asked Questions (FAQ)

Q: Can the AHF22 directly replace the AHF11 without PCB modifications?

A: The AHF22 is functionally equivalent but features horizontal mounting versus the AHF11's vertical orientation. Direct pin-for-pin replacement is possible if the PCB footprint accommodates horizontal component placement. If the original design requires vertical mounting, PCB layout modification is necessary.

Q: What is the impact of the operating temperature range difference?

A: The AHF11 operates from -25°C to 85°C, while the AHF22 operates from -20°C to 80°C. The AHF22 has a narrower range at both extremes. Applications operating below -20°C or above 80°C must use the AHF11 or identify alternative sensors. Most commercial and industrial applications fall within the AHF22 range.

Q: Are voltage and current specifications identical between the two parts?

A: The AHF11 specifies 5V ~ 30V supply voltage and 100mA output current. The AHF22 does not provide explicit voltage or current specifications in the available data. Verify with the manufacturer that the AHF22 meets your circuit's voltage and current requirements before substitution.

Q: Why is the AHF11 listed as obsolete?

A: Panasonic Electric Works has discontinued the AHF11 in favor of the AHF22, which offers the same functional performance with active manufacturing support. The AHF22 is the recommended path forward for new designs and legacy system replacements.

Q: What packaging differences exist between these components?

A: The AHF11 is supplied in standard packaging, while the AHF22 is supplied in tube packaging. Both maintain PCB mount form factors. Tube packaging typically indicates higher volume availability and standardized handling for automated assembly processes.
