Key Parameters

Substitute Part Grouping Explanation

Substitution of the 97R10SR is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, Grayhill 97R10SRT, maintains identical specifications for circuit configuration (SPST), position count (10), current rating (25mA), voltage rating (24VDC), actuator type (slide standard), mounting method (surface mount), termination style (gull wing), pitch (0.050"), contact material and finish (copper alloy with gold), operating temperature range (-40°C to 85°C), mechanical life (1,000 cycles), and washable capability.

The substitution is valid based on the following critical parameters:

• Electrical ratings: 25mA at 24VDC
• Mechanical configuration: 10-position SPST with standard slide actuator
• Physical form factor: Surface mount with gull wing termination at 0.050" pitch
• Environmental tolerance: -40°C to 85°C operating range
• Contact durability: Gold-plated copper alloy with 1,000-cycle mechanical life

Parameter Comparison

Engineering Selection Recommendations

The 97R10SRT is the direct functional equivalent for the obsolete 97R10SR. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 97R10SR is classified as obsolete, while the 97R10SRT maintains active production status. Additionally, the 97R10SRT achieves ROHS3 compliance, whereas the 97R10SR is RoHS non-compliant. For new designs or applications requiring regulatory compliance with current environmental standards, the 97R10SRT is the appropriate selection.

Both components maintain identical moisture sensitivity level (MSL 1, Unlimited), REACH unaffected status, and ECCN/HTSUS classifications, confirming regulatory equivalence for export and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can the 97R10SRT directly replace the 97R10SR in existing assemblies?

A: Yes. The 97R10SRT is electrically and mechanically equivalent to the 97R10SR. Both components feature identical SPST 10-position configuration, 25mA/24VDC ratings, surface mount gull wing termination at 0.050" pitch, and operating temperature range of -40°C to 85°C. No circuit modifications are required.

Q: What is the primary reason to transition from 97R10SR to 97R10SRT?

A: The 97R10SR is obsolete. The 97R10SRT is the active production equivalent. Additionally, the 97R10SRT achieves ROHS3 compliance, meeting current environmental regulatory requirements, whereas the 97R10SR does not.

Q: Are there packaging differences between these parts?

A: The 97R10SR packaging specification is listed as "-" (not specified). The 97R10SRT is supplied in Bulk packaging. Both components feature tape seal and identical physical dimensions (0.548" length, 0.061" height above board).

Q: Do these parts have identical mechanical life specifications?

A: Yes. Both the 97R10SR and 97R10SRT are rated for 1,000 mechanical cycles, ensuring equivalent durability and operational lifespan.

Q: Are moisture sensitivity levels the same?

A: Yes. Both components carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What are the contact material specifications?
