Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76RSB08S is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit configuration (SPST), number of positions (8), current rating (150mA), and voltage rating (30VDC) must be identical.

Mechanical Parameters: Actuator type (rocker), actuator level (flush/recessed), contact material (copper alloy), contact finish (gold), mounting type (through hole), termination style (PC pin), pitch (0.100"), height above board (0.292"), and length (0.880") must match exactly.

Environmental Parameters: Operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles) must be equivalent.

Compliance Parameters: Moisture sensitivity level (MSL 1) must be maintained.

The 76RSB08ST meets all substitution criteria and is identified as the direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 76RSB08ST is the direct functional equivalent of the 76RSB08S. All electrical, mechanical, and environmental parameters are identical. The primary distinction is product status: the 76RSB08S is obsolete while the 76RSB08ST maintains active status with Grayhill Inc.

The 76RSB08ST additionally provides improved regulatory compliance, meeting RoHS3 requirements compared to the non-compliant 76RSB08S. Both components maintain REACH Unaffected status and EAR99 export classification.

Packaging differs between the two parts: the 76RSB08S is supplied in bulk format, while the 76RSB08ST is supplied in tube packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance.

For new designs or component replacement in existing applications, the 76RSB08ST is the appropriate selection due to active product status and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB08ST directly replace the 76RSB08S in existing circuit designs?

A: Yes. The 76RSB08ST is electrically and mechanically identical to the 76RSB08S. All critical parameters including circuit configuration, current rating, voltage rating, actuator type, mounting dimensions, and operating temperature range are equivalent. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference between these parts?

A: The 76RSB08S is classified as obsolete, indicating Grayhill Inc. no longer manufactures this part number. The 76RSB08ST maintains active status, ensuring continued availability and manufacturing support. For procurement planning, the 76RSB08ST should be specified for new applications and component replenishment.

Q: How does the packaging difference affect component selection?

A: The 76RSB08S is supplied in bulk packaging while the 76RSB08ST is supplied in tube packaging. This affects storage, handling, and automated assembly processes but does not alter electrical or mechanical performance. Component selection should consider manufacturing and assembly requirements specific to your production environment.

Q: Does the RoHS3 compliance of the 76RSB08ST affect compatibility with designs using the 76RSB08S?

A: No. RoHS3 compliance indicates the 76RSB08ST meets stricter environmental and material restrictions. This represents an improvement over the non-compliant 76RSB08S and does not create compatibility issues. The 76RSB08ST is suitable for applications requiring RoHS compliance.

Q: Are there any electrical performance differences between the 76RSB08S and 76RSB08ST?

A: No. Both parts maintain identical electrical specifications: 150mA current rating, 30VDC voltage rating, 2,000 cycle mechanical and electrical life, and SPST circuit configuration. Performance in circuit applications is equivalent.

Q: What is the pitch specification and why is it important for substitution?

A: Both parts feature 0.100" (2.54mm) pitch, which defines the spacing between switch positions on the printed circuit board. Identical pitch ensures the 76RSB08ST fits existing PCB layouts designed for the 76RSB08S without modification.
