Parameter Comparison

Engineering Selection Recommendations

The CSNR161 is the direct substitute for the obsolete CSNR161-004. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical specifications, mechanical configuration, and compliance certifications. The primary distinction is product status: CSNR161-004 is obsolete, while CSNR161 maintains active product status.

Selection Basis:

1. Electrical Equivalence: All electrical parameters, including current sensing range (200A), supply voltage (±12V ~ 15V), accuracy (±0.5%), response time (0.5µs), and operating temperature range (-40°C ~ 85°C), are identical between the two parts.

2. Mechanical Compatibility: Both parts feature identical through-hole mounting, single pass-through module configuration, and bidirectional polarization, ensuring direct mechanical interchangeability in existing designs.

3. Compliance Alignment: Both parts are RoHS Compliant with MSL rating of 1 (Unlimited), meeting environmental and reliability standards.

4. Product Lifecycle: CSNR161 is an active product with established supply chains and long-term availability, whereas CSNR161-004 is obsolete. For new designs, maintenance activities, and long-term procurement, CSNR161 is the appropriate selection.

5. Packaging Consideration: CSNR161-004 is supplied in tape and reel packaging, while CSNR161 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can CSNR161 directly replace CSNR161-004 in existing applications?

A: Yes. The CSNR161 is electrically and mechanically equivalent to CSNR161-004. All critical parameters—current sensing capability (200A), supply voltage (±12V ~ 15V), accuracy (±0.5%), response time (0.5µs), operating temperature range (-40°C ~ 85°C), and mounting configuration (through-hole, single pass-through)—are identical. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between CSNR161-004 and CSNR161?

A: The primary difference is product status. CSNR161-004 is classified as obsolete, while CSNR161 is an active product. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical and mechanical specifications. The packaging format differs: CSNR161-004 uses tape and reel packaging, while CSNR161 uses bulk packaging. This packaging difference does not affect component performance or compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CSNR161-004 and CSNR161 are RoHS Compliant with an MSL rating of 1 (Unlimited). Compliance certifications and environmental standards are identical across both parts.

Q: Why should I transition from CSNR161-004 to CSNR161?

A: CSNR161-004 is obsolete, which creates supply chain risk and limits long-term availability. CSNR161 is an active product with established manufacturing and distribution channels, ensuring reliable procurement for current and future applications. Transitioning to CSNR161 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility.

Q: Does the packaging format affect component selection?

A: Packaging format (tape and reel versus bulk) does not affect electrical performance, mechanical compatibility, or functional characteristics. Selection between packaging formats is determined by procurement volume, handling requirements, and assembly process specifications, not by component performance.

Q: What parameters must remain identical for substitution to be valid?

A: For the CSNR161-004 / CSNR161 substitution, the following parameters must be identical: sensor type (Hall Effect, Closed Loop), current sensing range (200A), measurement capability (AC/DC), number of channels (1), output type (Ratiometric, Current), accuracy (±0.5%), supply voltage (±12V ~ 15V), response time (0.5µs), maximum supply current (14mA), operating temperature range (-40°C ~ 85°C), polarization (bidirectional), mounting type (through-hole), and package configuration (module, single pass-through). All these parameters are identical between the two parts.
