PEAA-3000 Equivalent & Substitute Parts

Part Overview

The PEAA-3000 is a thumbwheel switch decimal selector manufactured by ZF Electronics, designed for panel mount applications with snap-in installation. It provides 0–9 decimal output with 0.1A contact rating at 50VAC/DC. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PEAA-3000 is determined by the following critical parameters:

• Output Code & Read Out: Must be decimal format with 0–9 range
• Number of Sections: Must be single section
• Actuator Type: Must be pushwheel
• Mounting Configuration: Must support panel mount with snap-in installation
• Termination Style: Must use card edge/solder pad termination
• Physical Dimensions: Section width (7.62mm) and depth behind flange (32.00mm) must match
• Operating Temperature: Must support -20°C ~ 80°C range
• Contact Rating: Must support minimum 0.1A at voltage rating
• Regulatory Compliance: Must maintain ROHS3 compliance and EAR99 classification

The SMCD111AK2 manufactured by APEM Inc. meets all substitution criteria with the exception of contact voltage rating, which is specified at 40VAC/DC versus the original 50VAC/DC specification.

Parameter Comparison

Engineering Selection Recommendations

The SMCD111AK2 is an active product manufactured by APEM Inc. and maintains full compliance with ROHS3 and EAR99 export classification requirements. The primary design consideration is the contact voltage rating differential: the substitute operates at 40VAC/DC versus the original 50VAC/DC specification. All mechanical and functional parameters align with the original PEAA-3000, including mounting configuration, termination style, physical dimensions, and operating temperature range. The substitute is suitable for applications where the 40VAC/DC contact rating meets system voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can the SMCD111AK2 directly replace the PEAA-3000 in all applications?

A: The SMCD111AK2 is mechanically and functionally compatible with the PEAA-3000. The critical consideration is the contact voltage rating: the substitute is rated for 40VAC/DC while the original is rated for 50VAC/DC. Applications operating at or below 40VAC/DC can use the substitute without modification. Applications requiring 50VAC/DC operation must evaluate whether the lower rating is acceptable for the specific circuit design.

Q: Are the physical dimensions identical between these parts?

A: The mechanical dimensions are compatible. Both parts share identical section width (0.300"/7.62mm) and depth behind flange (32.00mm). Display character height differs slightly: PEAA-3000 is 0.196" (5.00mm) while SMCD111AK2 is 0.193" (4.90mm). This minor difference does not affect panel cutout compatibility or snap-in installation.

Q: What is the packaging difference?

A: The PEAA-3000 packaging specification is not provided in the original documentation. The SMCD111AK2 is supplied in tray packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Are both parts RoHS compliant?

A: Both the PEAA-3000 and SMCD111AK2 are ROHS3 compliant and carry EAR99 export classification. Both are suitable for applications with RoHS compliance requirements.

Q: What is the contact material difference?

A: The SMCD111AK2 specifies copper tin alloy contacts with gold finish. The PEAA-3000 contact material and finish specifications are not provided in the original documentation. Consult the original ZF Electronics datasheet if contact material compatibility is critical for your application.
