PACA-3000 Equivalent & Substitute Parts

Part Overview

The PACA-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

The PICOD131AK2 manufactured by APEM Inc. qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• BCD output code with 0 ~ 9 read out range
• Single section configuration
• 0.1A contact rating (within acceptable operating envelope)
• Pushwheel actuator type
• Panel mount, snap-in mechanical interface
• Card edge/solder pad termination
• 0.300" (7.62mm) section width
• 24.00mm depth behind flange
• Polyphenylene Oxide (PPO) housing material
• Black color
• ROHS3 compliance

Parameter Variance: The PICOD131AK2 operates at 0.1A @ 40VAC/DC, representing a reduced voltage rating compared to the PACA-3000 (50VAC/DC). The operating temperature range is -20°C ~ 60°C versus -20°C ~ 80°C. Display character height differs marginally (0.122" versus 0.120"). These variations remain within acceptable substitution tolerances for equivalent component selection.

Parameter Comparison

Engineering Selection Recommendations

The PICOD131AK2 is an active product from APEM Inc., providing supply continuity for the obsolete PACA-3000. Both components maintain ROHS3 compliance and identical export classification (EAR99). The substitute maintains mechanical and electrical interface compatibility through matching mounting type, termination style, and section dimensions.

Selection of the PICOD131AK2 is appropriate for applications where the 40VAC/DC contact rating and -20°C ~ 60°C operating temperature range satisfy system requirements. Applications requiring the full 50VAC/DC rating or extended upper temperature operation to 80°C must evaluate the voltage and temperature derating implications within their specific circuit design.

Frequently Asked Questions (FAQ)

Q: Can PICOD131AK2 directly replace PACA-3000 in existing designs?

A: Mechanical and electrical interface compatibility is confirmed. The reduced voltage rating (40VAC/DC versus 50VAC/DC) and narrower operating temperature range (-20°C ~ 60°C versus -20°C ~ 80°C) must be evaluated against application requirements. Identical BCD output code, section configuration, and mounting interface enable direct physical substitution where these parameter reductions are acceptable.

Q: What are the key differences between these components?

A: Contact rating voltage differs by 10VAC/DC. Operating temperature upper limit is 20°C lower on the substitute. Display character height varies by 0.002" (0.10mm). Contact material composition differs (Copper Alloy versus unspecified). All other critical parameters including output code, actuator type, mounting configuration, and termination style are identical.

Q: Are both components RoHS compliant?

A: Both PACA-3000 and PICOD131AK2 are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry identical HTSUS classification (8536.50.9065) and EAR99 export designation.

Q: What packaging is available for the substitute?

A: PICOD131AK2 is supplied in Tray packaging. PACA-3000 packaging specification was not provided in the reference data.

Q: Is the PICOD131AK2 currently in production?

A: Yes, PICOD131AK2 maintains Active product status with 1449 pieces available in current inventory, contrasting with the obsolete PACA-3000 status.
