Grayhill 25BSP22-G-1-11 Rotary Encoder Mechanical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 25BSP22-G-1-11 is an active mechanical rotary encoder with 16 pulses per revolution (PPR) output in Gray Code (Absolute) format. This right-angle PCB-mounted encoder is designed for applications requiring absolute position feedback with mechanical switching. The part is RoHS Compliant and REACH Unaffected, with unlimited moisture sensitivity rating (MSL 1). Alternative models within the Grayhill 25 series are available to support procurement flexibility, inventory optimization, and application-specific packaging requirements.

Substitute Part Grouping Explanation

Substitute parts for the 25BSP22-G-1-11 are qualified based on strict electrical and mechanical parameter alignment within the Grayhill 25 series. Substitution eligibility is determined by the following critical parameters:

Substitution Criteria:

• Encoder Type: Mechanical
• Output Type: Gray Code (Absolute)
• Pulses per Revolution: 16 PPR
• Actuator Type: 1/4" Dia Flatted End
• Mounting Type: PCB, Through Hole
• Orientation: Right Angle
• Termination Style: PC Pin
• Rotational Life: 50K cycles minimum
• Detent: No
• Built-in Switch: No

The substitute parts 25BSP22-G-1-08 and 25BSR22-G-1-16C meet all critical electrical and mechanical parameters. Variations exist only in packaging format and RoHS certification revision level, which do not affect functional compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—25BSP22-G-1-11, 25BSP22-G-1-08, and 25BSR22-G-1-16C—are active products from Grayhill Inc. with identical functional specifications for mechanical 16 PPR Gray Code absolute rotary encoding applications.

Compliance Status:

• 25BSP22-G-1-11: RoHS Compliant, REACH Unaffected
• 25BSP22-G-1-08: ROHS3 Compliant, REACH Unaffected
• 25BSR22-G-1-16C: ROHS3 Compliant, REACH Unaffected

The substitute parts carry ROHS3 certification, representing the current RoHS directive revision. Selection between these parts should be based on packaging requirements (standard vs. bulk) and internal procurement specifications regarding RoHS revision acceptance. All parts are functionally equivalent for PCB through-hole mounting applications requiring 16 PPR absolute position feedback.

Frequently Asked Questions (FAQ)

Q: Can 25BSP22-G-1-08 replace 25BSP22-G-1-11 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications: 16 PPR Gray Code (Absolute) output, 1/4" flatted end actuator, right-angle PCB through-hole mounting, and 50K cycle rotational life. The difference is packaging format (standard vs. bulk) and RoHS certification revision level, neither of which affects functional compatibility.

Q: What is the difference between 25BSP22-G-1-11 and 25BSR22-G-1-16C?

A: The base product numbers differ (25BSP22 vs. 25BSR22), but both deliver identical functional performance: 16 PPR mechanical Gray Code absolute encoding, right-angle orientation, and PC pin termination. Both are active products with equivalent compliance certifications (ROHS3, REACH Unaffected). Selection depends on packaging availability and procurement specifications.

Q: Are there any supply chain advantages to using substitute parts?

A: Yes. The substitute parts 25BSP22-G-1-08 (1018 Pcs in stock) and 25BSR22-G-1-16C (1188 Pcs in stock) have higher inventory levels compared to the main part 25BSP22-G-1-11 (734 Pcs in stock). This may provide improved lead times and procurement flexibility.

Q: Do all three parts meet current RoHS requirements?

A: Yes. The main part is RoHS Compliant. Both substitute parts carry ROHS3 Compliant certification, representing the current RoHS directive revision. All three are REACH Unaffected. Selection should align with your organization's RoHS revision acceptance policy.

Q: What packaging formats are available?

A: The main part 25BSP22-G-1-11 uses standard packaging. Substitute parts 25BSP22-G-1-08 and 25BSR22-G-1-16C are supplied in bulk packaging. Confirm packaging requirements with your procurement or assembly specifications before selection.

Q: Are these parts suitable for high-cycle applications?

A: All three parts are rated for 50K minimum rotational life cycles. Application suitability depends on specific duty cycle requirements. Verify that 50K cycles meets your application's operational lifespan expectations.
