Parameter Comparison

Engineering Selection Recommendations

The PEC12R-4130F-S0012 is the direct functional equivalent of the PEC12-4130F-S0012. Selection of the PEC12R variant is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance meets current regulatory requirements for electronic components
• Moisture Sensitivity Level 1 (Unlimited) provides superior handling flexibility compared to the original part's unspecified MSL rating
• Identical electrical and mechanical specifications guarantee pin-for-pin and form-factor compatibility
• Tray packaging supports efficient inventory management and automated assembly processes

Frequently Asked Questions (FAQ)

Q: Are the PEC12-4130F-S0012 and PEC12R-4130F-S0012 electrically identical?

A: Yes. Both parts feature identical encoder type (mechanical), output type (quadrature incremental), pulses per revolution (12), and rotational life specifications (30K cycles minimum).

Q: Can the PEC12R-4130F-S0012 be used as a direct replacement in existing designs?

A: Yes. The PEC12R-4130F-S0012 maintains identical mechanical specifications including actuator type (6mm dia flatted end), mounting configuration (PCB through hole vertical), and termination style (PC pin), enabling direct substitution without circuit board modifications.

Q: What is the primary advantage of transitioning to the PEC12R-4130F-S0012?

A: The PEC12R variant carries active product status and ROHS3 compliance, whereas the original PEC12-4130F-S0012 is obsolete and RoHS non-compliant. This transition ensures regulatory compliance and eliminates supply chain discontinuity risks.

Q: Does packaging differ between these parts?

A: Yes. The PEC12-4130F-S0012 packaging is unspecified, while the PEC12R-4130F-S0012 is supplied in tray packaging. Tray packaging is standard for automated assembly and provides improved component protection during storage and handling.

Q: Are there any functional differences in detent or switch operation?

A: No. Both parts include integrated detent and switch functionality with identical specifications.
