SCM031100 Equivalent & Substitute Parts

Part Overview

The SCM031100 is a 3-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry configuration. This component operates at 300V with a 20A current rating and accommodates wire gauges from 12-28 AWG. The product is currently active and RoHS compliant, making it suitable for industrial and commercial applications requiring reliable wire termination.

Equivalent parts are identified when alternative manufacturers offer terminal blocks with matching or superior electrical and mechanical specifications, enabling seamless integration into existing designs or providing supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCM031100 is determined by the following critical parameters:

• Electrical Compatibility: Voltage rating ≥ 300V, current rating ≥ 20A
• Mechanical Compatibility: 3 positions per level, 0.197" (5.00mm) pitch, horizontal with board orientation, through-hole mounting
• Termination Interface: Wire gauge accommodation of 12-28 AWG minimum
• Environmental Compliance: RoHS compliance status and operating temperature range

The substitute part 282856-3 meets these criteria with equivalent or superior electrical ratings and maintains mechanical interchangeability through identical pitch, position count, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

SCM031100 (Amphenol PCD): Select this part when the original design specification requires Amphenol PCD sourcing, screwless spring cage termination, or when the 125°C operating temperature specification is a design requirement. The product is active with established supply availability.

282856-3 (TE Connectivity): This substitute provides higher current capacity (24A vs. 20A) and extended wire gauge accommodation (12-30 AWG vs. 12-28 AWG). The part is ROHS3 compliant and maintains electrical and mechanical compatibility. Selection is appropriate when higher current margin or broader wire gauge support is beneficial. The screw-based rising cage clamp termination differs from the original design but provides equivalent functional performance for wire retention.

Both parts maintain identical pitch, position count, voltage rating, and through-hole mounting configuration, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can 282856-3 be used as a direct replacement for SCM031100?

A: Yes, 282856-3 is mechanically and electrically compatible. Both parts feature 3 positions at 0.197" (5.00mm) pitch with horizontal board orientation and 300V rating. The substitute provides superior current capacity (24A vs. 20A) and accommodates wire gauges from 12-30 AWG. The primary difference is the termination method: SCM031100 uses screwless spring cage termination, while 282856-3 uses screw-based rising cage clamp termination.

Q: Are there packaging differences between these parts?

A: Yes. SCM031100 is supplied in tray packaging, while 282856-3 is supplied in bulk packaging. Packaging selection should align with assembly process requirements and inventory management practices.

Q: What is the operating temperature difference?

A: SCM031100 specifies a maximum operating temperature of 125°C. The operating temperature for 282856-3 was not provided in the available specifications. Verify thermal requirements against your application before selection.

Q: Do both parts meet RoHS requirements?

A: Yes. SCM031100 is RoHS compliant. 282856-3 is ROHS3 compliant, which represents a more recent compliance standard. Both parts are suitable for applications requiring RoHS certification.

Q: What wire gauge range does each part support?

A: SCM031100 accommodates 12-28 AWG wire. 282856-3 accommodates 12-30 AWG wire, providing support for larger gauge conductors if required by the application.
