PEGA-3000 Thumbwheel Switch Hexadecimal Equivalent & Substitute Parts

Part Overview

The PEGA-3000 is a thumbwheel switch manufactured by ZF Electronics, designed for hexadecimal output applications requiring 0.1A @ 50VAC/DC contact rating. This panel mount, snap-in component operates across -20°C to 80°C and provides read-out values from 0 to 15. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEGA-3000 is based on the following critical parameters that must align across alternative components:

• Output code must be hexadecimal with read-out range 0 ~ 15
• Mounting configuration must be panel mount, snap-in
• Termination style must be card edge/solder pad
• Operating temperature range must encompass -20°C ~ 80°C
• Contact rating voltage must be compatible with 50VAC/DC applications
• RoHS3 compliance must be maintained

The substitute part 4-1437603-7 (TE Connectivity ALCOSWITCH Switches, DPS9 series) meets these core functional and mechanical requirements. While contact current rating differs (0.4VA @ 20VAC/DC versus 0.1A @ 50VAC/DC), the substitute operates within the same voltage envelope and provides equivalent hexadecimal switching functionality with identical output resolution and mounting architecture.

Parameter Comparison

Engineering Selection Recommendations

The 4-1437603-7 substitute part is suitable for applications where the PEGA-3000 is no longer available. Both components maintain ROHS3 compliance and operate within the specified temperature range. The substitute part carries active product status, ensuring continued availability and supply chain stability.

Selection of the substitute should account for the following provided specifications: the contact rating differs (0.4VA @ 20VAC/DC versus 0.1A @ 50VAC/DC), and physical dimensions vary slightly (display height, section width, and depth behind flange). These differences must be evaluated against specific application requirements and circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can the 4-1437603-7 directly replace the PEGA-3000 in all applications?

A: Both parts share identical hexadecimal output coding, read-out range (0 ~ 15), mounting type (panel mount, snap-in), and termination style (card edge/solder pad). However, contact rating specifications differ. The substitute operates at 0.4VA @ 20VAC/DC while the original operates at 0.1A @ 50VAC/DC. Physical dimensions also vary. Compatibility depends on specific circuit requirements and available panel space.

Q: What are the key functional similarities between these parts?

A: Both components provide hexadecimal output with identical 0 ~ 15 read-out range, single-section configuration, pushwheel actuation, and panel mount snap-in installation. Operating temperature ranges are identical (-20°C ~ 80°C), and both maintain ROHS3 compliance.

Q: Are there dimensional considerations for substitution?

A: Yes. The substitute part 4-1437603-7 has a larger display character height (0.169" versus 0.134"), slightly wider section width (0.315" versus 0.300"), and greater depth behind flange (39.00mm versus 32.00mm). Panel cutout dimensions and available mounting space must be verified before substitution.

Q: What is the significance of the product status difference?

A: The PEGA-3000 is classified as obsolete, while the 4-1437603-7 is active. Active status indicates ongoing manufacturer support, availability, and supply chain continuity for the substitute part.
