PECA-3000 Equivalent & Substitute Parts

Part Overview

The PECA-3000 is a thumbwheel switch manufactured by ZF Electronics, designed for BCD output applications requiring 0.1A contact rating at 50VAC/DC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The switch features panel mount, snap-in installation with card edge/solder pad termination, suitable for applications requiring manual numeric input selection from 0 to 9.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PECA-3000 is determined by the following critical parameters:

• Output code must be BCD
• Read out range must be 0 ~ 9
• Number of sections must be 1
• Actuator type must be Pushwheel
• Mounting type must be Panel Mount, Snap-In
• Termination style must be Card Edge/Solder Pad
• Section width must be 0.300" (7.62mm)
• Depth behind flange must be 32.00mm
• Operating temperature range must be -20°C ~ 80°C

The SMCD131AK2 manufactured by APEM Inc. meets all substitution criteria. While the contact rating differs (0.1A @ 40VAC/DC versus 0.1A @ 50VAC/DC), this represents a conservative electrical specification suitable for applications originally designed for the PECA-3000. The mechanical form factor, output encoding, and mounting interface are identical.

Parameter Comparison

Engineering Selection Recommendations

The SMCD131AK2 is the direct functional equivalent for PECA-3000 replacement. Both components maintain ROHS3 compliance and identical moisture sensitivity classification. The SMCD131AK2 carries active product status from APEM Inc., ensuring ongoing availability and supply chain continuity. The contact rating specification of 0.1A @ 40VAC/DC is conservative relative to the original 50VAC/DC rating, making it suitable for direct substitution in existing circuit designs. The marginal difference in display character height (0.193" versus 0.196") does not affect mechanical compatibility or functional performance.

Frequently Asked Questions (FAQ)

Q: Can the SMCD131AK2 directly replace the PECA-3000 without circuit modification?

A: Yes. The SMCD131AK2 maintains identical mechanical form factor, mounting interface, termination style, and BCD output encoding. The lower contact voltage rating (40VAC/DC versus 50VAC/DC) is conservative and compatible with existing circuit designs.

Q: What is the significance of the contact rating difference?

A: The SMCD131AK2 specifies 0.1A @ 40VAC/DC while the PECA-3000 specifies 0.1A @ 50VAC/DC. This represents a reduced maximum voltage specification. Applications operating at or below 40VAC/DC experience no functional impact. Applications requiring operation above 40VAC/DC must be evaluated against actual circuit voltage levels.

Q: Are the packaging formats compatible?

A: The PECA-3000 packaging format is not specified in available documentation. The SMCD131AK2 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both components support the same temperature operating range?

A: Yes. Both the PECA-3000 and SMCD131AK2 operate across -20°C to 80°C, ensuring thermal compatibility in equivalent applications.

Q: What compliance certifications apply to both components?

A: Both components are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
