Honeywell SS49 Hall Effect Sensor - Equivalent & Substitute Parts

Part Overview

The Honeywell SS49 is a single-axis Hall Effect analog voltage sensor designed for magnetic field detection applications. This component operates within a 4V to 10V supply voltage range and delivers analog output suitable for direct signal conditioning. The SS49 is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations. The part is RoHS compliant and rated for operation across -40°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS49 is determined by the following critical parameters:

Technology Match: Both the main part and substitute must utilize Hall Effect sensing technology for single-axis magnetic field detection.

Output Configuration: Analog voltage output is required to maintain compatibility with existing signal conditioning circuits.

Mounting and Packaging: Through-hole mounting capability is essential for PCB integration. Package form factor differences (3-SIP versus TO-226-3/TO-92-3) are acceptable provided the pin configuration and electrical interface remain compatible.

Supply Voltage Range: The substitute part must operate within overlapping or compatible supply voltage specifications. The SS49 operates at 4V to 10V; substitute parts with lower minimum voltage requirements (2.7V) remain compatible when supplied within the original operating range.

Temperature Rating: Operating temperature range must encompass or match the original specification of -40°C to 100°C.

Compliance: RoHS compliance status must be maintained for regulatory continuity.

The SS49E is identified as the manufacturer-recommended substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SS49 is classified as obsolete. The SS49E is an active product from the same manufacturer, ensuring continued availability and supply chain stability for new procurements and system maintenance.

Compliance Continuity: Both parts maintain RoHS compliance and identical MSL ratings, supporting regulatory requirements and manufacturing process compatibility.

Electrical Parameter Differences: The SS49E operates at a lower supply voltage range (2.7V to 6.5V) compared to the SS49 (4V to 10V). When the SS49E is supplied within the 4V to 10V range, it operates within its specified limits. However, the SS49E exhibits higher maximum supply current (10mA versus 4mA typical) and lower maximum output current (10mA versus 20mA). These differences require verification against circuit load requirements.

Temperature Rating: The SS49E upper operating temperature limit is 85°C, compared to 100°C for the SS49. Applications requiring operation above 85°C must retain the original SS49 or identify alternative solutions.

Package Transition: The shift from 3-SIP to TO-226-3 or TO-92-3 Short Body packaging requires PCB layout modification. Pin compatibility must be confirmed during design transition.

Frequently Asked Questions (FAQ)

Q: Can the SS49E directly replace the SS49 in existing designs?

A: Direct replacement requires verification of three factors: (1) supply voltage remains within 4V to 6.5V range, (2) output current load does not exceed 10mA, and (3) operating temperature does not exceed 85°C. PCB layout modification is necessary due to package form factor change.

Q: What is the primary reason for substitution?

A: The SS49 is obsolete. The SS49E is the manufacturer-recommended active substitute, ensuring component availability and supply continuity.

Q: Are there electrical compatibility concerns?

A: The SS49E has lower maximum output current (10mA versus 20mA) and a reduced upper operating temperature (85°C versus 100°C). Circuit designs must operate within these constraints.

Q: Do both parts share the same compliance certifications?

A: Yes. Both the SS49 and SS49E are RoHS compliant with MSL rating of 1 (Unlimited), supporting identical manufacturing and environmental requirements.

Q: What package changes occur during substitution?

A: The SS49 uses 3-SIP packaging, while the SS49E uses TO-226-3 or TO-92-3 Short Body packaging. Pin configuration compatibility must be confirmed, and PCB footprint redesign is required.

Q: Is the SS49E suitable for high-temperature applications above 85°C?

A: No. The SS49E is rated to 85°C maximum. Applications requiring operation to 100°C must identify alternative solutions or retain the original SS49 if available.
