Bourns PEC09-2325F-S0015 Rotary Encoder Mechanical 15PPR Equivalent & Substitute Parts

Part Overview

The Bourns PEC09-2325F-S0015 is an active mechanical rotary encoder with 15 pulses per revolution (PPR), quadrature incremental output, and right-angle orientation. This encoder features a 6mm diameter flatted-end actuator, integrated detent mechanism, and built-in switch functionality. The part is mounted via panel or PCB through-hole configuration with PC pin termination. With 30,000 minimum rotational life cycles and ROHS3 compliance, this component is suitable for industrial control, instrumentation, and consumer electronics applications requiring precise rotational position feedback.

Substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from compatible variants within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PEC09-2325F-S0015 is determined by the following critical parameters:

Mechanical Compatibility Parameters:

• Actuator Type: 6mm Dia Flatted End (must match)
• Mounting Type: Panel, PCB Through Hole (must match)
• Orientation: Right Angle (must match)
• Termination Style: PC Pin (must match)
• Detent: Yes (must match)
• Built-in Switch: Yes (must match)

Functional Parameters:

• Encoder Type: Mechanical (must match)
• Output Type: Quadrature (Incremental) (must match)

Allowable Variation Parameters:

• Pulses per Revolution: 12 or 15 PPR (application-dependent)
• Rotational Life: 30K or 100K cycles (higher values are backward compatible)
• Series: PEC09 or PEC16 (same family, compatible mechanical envelope)

Substitute parts maintain identical mechanical interfaces and electrical output characteristics while permitting variation in resolution (PPR) and operational durability (rotational life cycles) based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (15 PPR, 30K Cycles):

• PEC09-2320F-S0015: Identical electrical and mechanical specifications to the primary part number. Suitable for direct substitution in all applications.
• PEC09-2320F-T0015: Identical specifications with alternative packaging designation. Suitable for direct substitution in all applications.

Resolution Variants (12 PPR, 30K Cycles):

• PEC09-2120F-S0012: Lower resolution encoder within the same PEC09 series. Applicable when application requirements permit 12 PPR resolution instead of 15 PPR.
• PEC09-2220F-S0012: Lower resolution encoder within the same PEC09 series. Applicable when application requirements permit 12 PPR resolution instead of 15 PPR.

Enhanced Durability Variant (12 PPR, 100K Cycles):

• PEC16-2120F-S0012: Different series (PEC16) with extended rotational life of 100,000 cycles. Applicable when higher durability is required, with the trade-off of 12 PPR resolution. This part maintains mechanical compatibility with identical actuator, mounting, and termination specifications.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the primary part number.

Frequently Asked Questions (FAQ)

Q: Can PEC09-2320F-S0015 be used as a direct replacement for PEC09-2325F-S0015? A: Yes. Both parts share identical electrical output (15 PPR quadrature), mechanical interface (6mm flatted-end actuator, right-angle orientation, PC pin termination), and operational durability (30K cycles minimum). These parts are functionally equivalent.

Q: What is the difference between 15 PPR and 12 PPR encoders? A: Pulses per revolution (PPR) defines the resolution of rotational position feedback. A 15 PPR encoder generates 15 quadrature pulses per complete rotation, while a 12 PPR encoder generates 12 pulses per rotation. Selection depends on the application's required angular resolution. Lower PPR values reduce computational overhead but provide coarser position feedback.

Q: Is the PEC16-2120F-S0012 mechanically compatible with PEC09 series applications? A: Yes. The PEC16-2120F-S0012 maintains identical mechanical specifications: 6mm flatted-end actuator, right-angle orientation, panel and PCB through-hole mounting, and PC pin termination. The primary difference is extended rotational life (100K cycles versus 30K cycles). This part is suitable for applications requiring higher durability.

Q: What does "Detent: Yes" and "Built-in Switch: Yes" mean? A: Detent refers to the mechanical positioning mechanism that provides tactile feedback and holds the encoder at discrete angular positions. Built-in switch indicates an integrated push-button switch function accessible through the encoder actuator. Both features are present in all listed substitute parts.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (PEC09-2120F-S0012, PEC09-2220F-S0012, PEC09-2320F-S0015, PEC09-2320F-T0015, and PEC16-2120F-S0012) are ROHS3 compliant and REACH unaffected, ensuring regulatory equivalence.

Q: What is the difference between packaging designations "S" and "T" in part numbers? A: The packaging designation (S or T) indicates the physical packaging format for shipment and storage. Both PEC09-2320F-S0015 and PEC09-2320F-T0015 are electrically and mechanically identical; the designation reflects only the packaging method used by the manufacturer.
