PEC12-4017F-S0024 Equivalent & Substitute Parts

Part Overview

The PEC12-4017F-S0024 is a mechanical rotary encoder manufactured by Bourns Inc., configured for 24 pulses per revolution with quadrature (incremental) output. This encoder features a 6mm diameter flatted end actuator, built-in switch functionality, and vertical PCB through-hole mounting with PC pin termination. The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure component availability for production and service applications.

Substitute Part Grouping Explanation

Substitution eligibility for the PEC12-4017F-S0024 is determined by the following critical parameters: encoder type (mechanical), output type (quadrature incremental), pulses per revolution (24), actuator type (6mm diameter flatted end), built-in switch presence, mounting configuration (PCB through-hole vertical), and termination style (PC pin). All substitute parts must maintain identical specifications across these parameters to ensure functional and mechanical compatibility.

The primary direct substitute is PEC12R-4017F-S0024, which shares all functional and mechanical parameters with the original part while offering active product status. Additional substitutes PEC12R-4020F-S0024 and PEC12R-4025F-S0024 maintain identical 24 PPR specifications. Parts PEC12R-4020F-S0012 and PEC12R-4030F-S0012 are classified as similar alternatives due to reduced pulse-per-revolution specification (12 PPR instead of 24 PPR) and are suitable only for applications where lower resolution is acceptable.

Engineering Selection Recommendations

For direct replacement of the obsolete PEC12-4017F-S0024, select PEC12R-4017F-S0024. This part maintains identical electrical and mechanical specifications while offering active product status and improved moisture sensitivity rating (MSL 1 Unlimited versus Not Applicable). All substitute parts listed are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.

Alternative 24 PPR options PEC12R-4020F-S0024 and PEC12R-4025F-S0024 provide functional equivalence with active availability. Selection among these three 24 PPR variants may be based on packaging preferences and inventory availability, as all three maintain identical electrical performance and mechanical compatibility.

Parts PEC12R-4020F-S0012 and PEC12R-4030F-S0012 are suitable only for applications where 12 PPR resolution is functionally acceptable. These parts must not be used as substitutes in designs requiring 24 PPR output resolution.

Frequently Asked Questions (FAQ)

Q: Can PEC12R-4017F-S0024 be used as a direct replacement for PEC12-4017F-S0024?

A: Yes. PEC12R-4017F-S0024 is the direct equivalent, maintaining all functional parameters including 24 PPR output, quadrature encoding, 6mm flatted end actuator, built-in switch, vertical PCB through-hole mounting, and PC pin termination. The primary difference is active product status and improved moisture sensitivity rating.

Q: What is the difference between the 24 PPR and 12 PPR substitute options?

A: Pulses per revolution directly determines encoder resolution. The 24 PPR variants (PEC12R-4017F-S0024, PEC12R-4020F-S0024, PEC12R-4025F-S0024) provide twice the angular resolution compared to 12 PPR variants (PEC12R-4020F-S0012, PEC12R-4030F-S0012). Selection depends on application resolution requirements. 12 PPR parts are not suitable for applications designed for 24 PPR output.

Q: Are all substitute parts mechanically compatible with the original PCB footprint?

A: Yes. All listed substitutes share identical mounting type (PCB through-hole), orientation (vertical), actuator type (6mm diameter flatted end), and termination style (PC pin). Mechanical compatibility is maintained across all variants.

Q: What packaging formats are available for substitute parts?

A: All substitute parts are supplied in Tray packaging. The original PEC12-4017F-S0024 packaging format is not specified in available documentation.

Q: Do all substitute parts meet current compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and carry REACH Unaffected status. All maintain 30K minimum rotational life specification and are rated for identical environmental conditions.
