PEC12-4020F-S0024 Rotary Encoder Equivalent & Substitute Parts

Part Overview

The PEC12-4020F-S0024 is a mechanical rotary encoder manufactured by Bourns Inc., featuring 24 pulses per revolution with quadrature (incremental) output. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The encoder is designed for vertical PCB mounting with through-hole termination and includes an integrated switch function. Substitute parts must maintain compatibility with the core electrical and mechanical specifications to ensure drop-in replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the PEC12-4020F-S0024 is determined by the following critical parameters: encoder type (mechanical), output type (quadrature incremental), pulses per revolution (24), actuator type (6mm dia flatted end), built-in switch presence, mounting configuration (PCB through-hole vertical), and termination style (PC pin). All substitute parts must match these specifications to ensure functional equivalence.

Substitute parts are grouped into two categories:

Direct Equivalent (24 PPR): PEC12R-4020F-S0024 and PEC12R-4025F-S0024 maintain identical pulses per revolution and are fully compatible replacements.

Alternative Resolution (12 PPR): PEC12R-4020F-S0012 and PEC12R-4030F-S0012 operate at 12 pulses per revolution, representing a different resolution option. These parts share all other mechanical and electrical characteristics but differ in output resolution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (24 PPR - Direct Equivalents):

PEC12R-4020F-S0024 is the recommended direct replacement for the obsolete PEC12-4020F-S0024. Both parts maintain identical pulses per revolution (24 PPR), mechanical configuration, and electrical output characteristics. The PEC12R-4020F-S0024 carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

PEC12R-4017F-S0024 and PEC12R-4025F-S0024 are functionally equivalent alternatives, also operating at 24 PPR with identical mechanical and electrical specifications. These parts are suitable for applications where the specific variant designation is not critical to system performance.

Alternative Substitutes (12 PPR - Resolution Variants):

PEC12R-4020F-S0012 and PEC12R-4030F-S0012 operate at 12 pulses per revolution, representing half the output resolution of the main part. These variants are applicable only in designs where reduced encoder resolution is acceptable or where firmware can accommodate the lower pulse count. All other mechanical and electrical parameters remain consistent with the main part specifications.

All substitute parts are ROHS3 compliant and carry active product status, ensuring regulatory compliance and ongoing manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can PEC12R-4020F-S0024 be used as a direct replacement for PEC12-4020F-S0024?

A: Yes. PEC12R-4020F-S0024 maintains identical specifications across all critical parameters: 24 PPR output, mechanical encoder type, quadrature incremental output, 6mm flatted-end actuator, integrated switch, vertical PCB through-hole mounting, and PC pin termination. The primary difference is product status (active vs. obsolete) and packaging format (tray).

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

A: Pulses per revolution (PPR) determines output resolution. The 24 PPR variants (PEC12-4020F-S0024, PEC12R-4020F-S0024, PEC12R-4017F-S0024, PEC12R-4025F-S0024) provide twice the resolution of 12 PPR variants (PEC12R-4020F-S0012, PEC12R-4030F-S0012). Selection depends on application requirements for rotational precision and firmware capability to process pulse counts.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts, including the main part PEC12-4020F-S0024, are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What packaging formats are available for substitute parts?

A: All substitute parts in the PEC12R series are supplied in tray packaging. The original PEC12-4020F-S0024 packaging format is not specified in available documentation.

Q: Why is the PEC12-4020F-S0024 classified as obsolete?

A: The PEC12-4020F-S0024 has been superseded by the active PEC12R series variants. Bourns Inc. recommends transitioning to PEC12R-4020F-S0024 or equivalent alternatives for new designs and ongoing production support.

Q: Are there any electrical parameter differences between substitute parts?

A: No. All substitute parts maintain identical electrical specifications: mechanical encoder type, quadrature incremental output, 30K minimum rotational life cycles, and no supply voltage requirement. Differences are limited to pulses per revolution (24 vs. 12 PPR) and product series designation (PEC12 vs. PEC12R).
