PEC11-4230F-S0024 Rotary Encoder Mechanical 24PPR Equivalent & Substitute Parts
Part Overview
The PEC11-4230F-S0024 is a mechanical rotary encoder manufactured by Bourns Inc., classified as an obsolete product with 1,038 units currently in stock. This encoder features 24 pulses per revolution with quadrature (incremental) output, a 6mm diameter flatted end actuator, integrated detent and built-in switch functionality, and vertical panel/PCB through-hole mounting. The product is ROHS3 compliant with a minimum rotational life of 30,000 cycles.
As this part is obsolete, identifying equivalent and substitute components is essential for design continuity, system maintenance, and long-term supply chain planning. Substitute parts must maintain compatibility across encoder type, output configuration, mounting orientation, and termination style while accommodating variations in pulses per revolution and rotational life specifications.

Engineering Selection Recommendations
Direct Replacement (Identical Specifications): PEC11R-4230F-S0024 is the primary substitute for PEC11-4230F-S0024. Both parts maintain 24 PPR resolution, 30K minimum rotational life, and identical mechanical/electrical characteristics. The PEC11R variant is currently in active production status with 3,628 units in stock, providing superior supply chain continuity compared to the obsolete original part.
Enhanced Durability Alternative (24 PPR): PEC11H-4215F-S0024 provides identical 24 PPR resolution with upgraded rotational life specification of 100K cycles. This variant incorporates ball/spring detent mechanics and is suitable for applications requiring extended operational life. Active product status with 1,955 units available.
Resolution Alternatives (Active Production): For applications where PPR resolution can be adjusted in firmware or system configuration:
- PEC11H-4120F-S0020 (20 PPR, 100K cycles, 1,544 units)
- PEC11H-4015F-S0016 (16 PPR, 100K cycles, 1,807 units)
- PEC11D-4120F-S0015 (15 PPR, 15K cycles, 954 units)
All alternatives maintain mechanical compatibility, vertical orientation, panel/PCB mounting, and PC pin termination. Selection depends on system tolerance for PPR variation and rotational life requirements.
Compliance Consideration: All substitute parts maintain ROHS3 compliance. PEC11H and PEC11D series variants carry REACH Affected status, requiring verification against specific application regulatory requirements.
Frequently Asked Questions (FAQ)
Q: Can PEC11R-4230F-S0024 be used as a direct replacement for PEC11-4230F-S0024? A: Yes. PEC11R-4230F-S0024 is electrically and mechanically identical to the original part, with matching 24 PPR output, 30K rotational life, and all mechanical specifications. The primary advantage is active production status versus obsolete classification.
Q: What is the difference between PEC11H and PEC11D encoder variants? A: PEC11H encoders feature ball/spring detent mechanics with 100K rotational life cycles. PEC11D encoders feature dual concentric design with lower rotational life (15K cycles). Both maintain quadrature output and vertical mounting compatibility. Selection depends on mechanical feel preference and durability requirements.
Q: Can I substitute a 20 PPR encoder (PEC11H-4120F-S0020) for the 24 PPR original? A: Substitution is possible only if the application firmware or system configuration can accommodate PPR resolution change. The mechanical and electrical interfaces remain compatible. Verify that 20 PPR resolution meets system accuracy and control requirements before implementation.
Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance. However, PEC11H and PEC11D series variants are classified as REACH Affected, requiring regulatory verification for specific end-use applications and geographic markets.
Q: What is the packaging difference between the original and substitutes? A: PEC11-4230F-S0024 is supplied in standard packaging. Substitute parts are supplied in Tray packaging. Both packaging formats are compatible with standard component handling and assembly processes. Verify tray specifications against your assembly equipment requirements.
Q: Which substitute offers the longest operational life? A: PEC11H series variants (PEC11H-4215F-S0024, PEC11H-4120F-S0020, PEC11H-4015F-S0016) all specify 100K minimum rotational life cycles, compared to 30K cycles for the original PEC11-4230F-S0024. This represents a 3.3x improvement in rated durability.
