Engineering Selection Recommendations

The 76HPSB04GWRT is the direct functional equivalent to the 76HPSB04GWR. Selection between these parts should be based on the following factors:

Product Status Consideration: The 76HPSB04GWR is classified as Obsolete, while the 76HPSB04GWRT maintains Active status. For new designs or ongoing production requiring long-term component availability, the 76HPSB04GWRT is the appropriate selection.

Compliance and Certification: The 76HPSB04GWRT achieves RoHS3 compliance, whereas the 76HPSB04GWR is RoHS non-compliant. Applications subject to RoHS regulatory requirements must utilize the 76HPSB04GWRT. Both parts maintain REACH Unaffected status and carry identical ECCN and HTSUS classifications.

Packaging Format: The 76HPSB04GWR is supplied in bulk packaging, while the 76HPSB04GWRT is supplied in Tape & Reel format. Packaging selection depends on production volume requirements and assembly line automation capabilities.

Electrical and Mechanical Equivalence: Both parts are identical in all functional parameters, including circuit configuration, current and voltage ratings, actuator characteristics, mounting specifications, and lifecycle ratings. Direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can the 76HPSB04GWRT be used as a direct replacement for the 76HPSB04GWR in existing designs?

A: Yes. The 76HPSB04GWRT is electrically and mechanically equivalent to the 76HPSB04GWR across all functional parameters. Both components share identical circuit configuration, current and voltage ratings, actuator type, mounting specifications, and lifecycle characteristics. Direct substitution is valid from a technical standpoint.

Q: What is the primary difference between these two parts?

A: The primary differences are product status, packaging format, and RoHS compliance. The 76HPSB04GWR is Obsolete and supplied in bulk packaging with RoHS non-compliant status. The 76HPSB04GWRT is Active, supplied in Tape & Reel format, and RoHS3 compliant.

Q: Why should I select the 76HPSB04GWRT over the 76HPSB04GWR?

A: The 76HPSB04GWRT should be selected for new designs or ongoing production due to its Active product status, ensuring long-term availability. Additionally, RoHS3 compliance is required for applications subject to regulatory restrictions on hazardous substances. Tape & Reel packaging is preferred for automated assembly processes.

Q: Are there any compatibility concerns when switching from 76HPSB04GWR to 76HPSB04GWRT?

A: No compatibility concerns exist. Both parts are identical in footprint, pinout, electrical performance, and mechanical characteristics. PCB layout and circuit design require no modification.

Q: What does the "TR" designation in 76HPSB04GWRT indicate?

A: The "TR" suffix indicates Tape & Reel packaging format, which is standard for automated surface mount assembly processes. This differs from the bulk packaging of the 76HPSB04GWR.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 76HPSB04GWR and 76HPSB04GWRT operate across the identical temperature range of -40°C to 85°C.
