Weidmüller 997228 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 997228 is a 7-position wire-to-board terminal block with horizontal mating orientation and 0.200" (5.08mm) pitch, designed for through-hole PCB mounting with screw wire termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical connectivity, mechanical fit, and PCB mounting characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 997228 is based on the following critical parameters that must remain constant:

• Electrical Configuration: 7 positions per level, 2 levels total
• Mechanical Fit: 0.200" (5.08mm) pitch spacing
• PCB Interface: Through-hole mounting with identical footprint
• Termination Method: Screw-based wire clamping
• Mating Orientation: Horizontal with board alignment

The substitute part Weidmüller 1768900000 satisfies all these criteria while offering the advantage of active product status and enhanced electrical specifications. Both parts share identical positional configuration, pitch, mounting type, and wire termination methodology, enabling direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1768900000 serves as the direct active equivalent for the obsolete 997228 terminal block. Selection of this substitute is supported by:

• Identical Mechanical Interface: Matching pitch, position count, and through-hole mounting footprint ensure PCB compatibility without layout modification
• Compliance Alignment: Both parts maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements
• Active Product Status: The 1768900000 is classified as active, ensuring long-term availability and supply chain continuity
• Enhanced Electrical Specifications: The substitute provides documented current (15 A), voltage (300 V), and temperature range (-50°C ~ 120°C) ratings, offering improved design documentation for new applications

For applications where the original 997228 specifications are fully documented and verified, the 1768900000 provides equivalent functionality with the added benefit of active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1768900000 be used as a direct replacement for the 997228 in existing designs?

A: Yes. Both parts share identical pitch (0.200"/5.08mm), position configuration (7 positions, 2 levels), through-hole mounting type, and screw termination method. PCB footprints are compatible without modification.

Q: What is the primary difference between these two parts?

A: The 997228 is obsolete with unspecified electrical ratings, while the 1768900000 is an active product from the Omnimate LM series with documented electrical specifications (15 A, 300 V) and operating temperature range (-50°C ~ 120°C).

Q: Does the color difference (black vs. orange) affect electrical performance?

A: No. Color is a cosmetic designation and does not impact electrical function or mechanical compatibility. The orange color of the 1768900000 is a series identifier for the Omnimate LM product line.

Q: Are both parts RoHS compliant?

A: Yes. Both the 997228 and 1768900000 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging options are available?

A: The 997228 is supplied in standard packaging, while the 1768900000 is available in bulk packaging. Both formats support production and maintenance inventory requirements.

Q: Is the wire gauge specification important for substitution?

A: The 1768900000 supports 14-24 AWG wire gauge. Verify that your application wire gauge falls within this range. The original 997228 does not specify wire gauge limits in available documentation.
