Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Grayhill 76MRSB07S is based on strict electrical and mechanical parameter matching within the Grayhill 76 series product line. The substitute part 76RSB07ST maintains complete compatibility through identical specifications across all critical parameters:

Electrical Parameters (Must Match):

• Circuit configuration: SPST topology
• Current rating: 150mA
• Voltage rating: 30VDC
• Contact material and finish: Copper alloy with gold plating
• Mechanical life: 2,000 cycles
• Electrical life: 2,000 cycles

Mechanical Parameters (Must Match):

• Number of positions: 7
• Actuator type: Rocker with flush/recessed level
• Mounting method: Through hole
• Pitch spacing: 0.100" (2.54mm)
• Height above board: 0.292" (7.41mm)
• Termination style: PC pin
• Body material: Thermoplastic

Environmental & Compliance Parameters (Must Match):

• Operating temperature range: -40°C to 85°C
• RoHS3 compliance status
• Moisture sensitivity level: MSL 1
• REACH unaffected status

The primary distinction between the main part and substitute is product status (obsolete versus active) and packaging format (tape seal versus tube packaging). These differences do not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 76RSB07ST serves as the direct functional equivalent for the obsolete 76MRSB07S. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The 76MRSB07S carries obsolete status, indicating discontinued manufacturing and limited long-term availability. The 76RSB07ST maintains active product status within the Grayhill 76 series, ensuring continued supply chain access and manufacturing support.

Compliance & Certification Alignment: Both parts maintain identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current and future production. Moisture sensitivity level MSL 1 (unlimited) provides equivalent handling flexibility for both components.

Electrical & Mechanical Compatibility: Complete parameter matching across all electrical ratings (150mA, 30VDC, SPST configuration), mechanical specifications (7-position rocker actuator, 0.100" pitch, through-hole mounting), and environmental operating range (-40°C to 85°C) ensures direct substitution without circuit redesign or PCB layout modification.

Packaging Consideration: The substitute part is supplied in tube packaging rather than tape seal format. This difference affects component handling and automated assembly processes but does not impact electrical or mechanical performance. Assembly operations must accommodate the packaging format change in pick-and-place equipment configuration.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB07ST be used as a direct replacement for the 76MRSB07S in existing designs?

A: Yes. The 76RSB07ST provides complete electrical and mechanical compatibility with the 76MRSB07S. All critical parameters including circuit configuration, current and voltage ratings, actuator type, mounting method, pitch spacing, and operating temperature range are identical. No circuit redesign or PCB layout modification is required.

Q: What is the primary reason for substitution?

A: The 76MRSB07S is classified as obsolete, indicating discontinued manufacturing. The 76RSB07ST is an active product within the same Grayhill 76 series, providing continued availability and manufacturing support for new production and design updates.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts maintain identical electrical specifications: SPST circuit configuration, 150mA current rating, 30VDC voltage rating, copper alloy contacts with gold finish, and 2,000-cycle mechanical and electrical life ratings.

Q: How do the packaging formats differ?

A: The 76MRSB07S is supplied with tape seal packaging, while the 76RSB07ST uses tube packaging. This affects component handling and automated assembly processes but does not impact electrical or mechanical performance. Assembly equipment must be configured to accommodate the tube packaging format.

Q: Are compliance certifications maintained with the substitute part?

A: Yes. The 76RSB07ST maintains identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity level as the 76MRSB07S. All regulatory requirements are satisfied.

Q: What is the physical compatibility for PCB mounting?

A: Physical compatibility is complete. Both parts share identical through-hole mounting specifications, 0.100" (2.54mm) pitch spacing, 0.292" (7.41mm) height above board, and 0.780" (19.81mm) length. Existing PCB footprints require no modification.

Q: Can the 76RSB07ST be used in applications requiring washable components?

A: Yes. The 76RSB07ST is rated as washable, matching the 76MRSB07S specification. Both parts support post-assembly cleaning processes.

Q: What is the operating temperature range for the substitute part?

A: The 76RSB07ST operates across the identical temperature range as the 76MRSB07S: -40°C to 85°C. Environmental performance is equivalent.

Q: Are there any inventory or lead time advantages to using the substitute part?

A: The 76RSB07ST carries active product status with current manufacturing support, providing improved long-term availability compared to the obsolete 76MRSB07S. Inventory levels and lead times reflect active product line status.
