Weidmüller 1976730000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1976730000 is a 16-position terminal block header with male pins, shrouded on four sides, featuring a 0.150" (3.81mm) pitch and 135° through-hole mounting. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement planning. The part operates within IEC ratings of 17.5A at 320V and UL ratings of 10A at 300V, with a temperature range of -50°C to 120°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1976730000 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current and voltage ratings (IEC: 17.5A/320V; UL: 10A/300V)
• Physical Configuration: 16 positions, 0.150" (3.81mm) pitch, 135° orientation
• Connector Type: Header with male pins, shrouded on four sides
• Mounting Method: Through-hole termination
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, operating temperature range -50°C to 120°C
• Contact Material: Copper alloy with tin mating finish

The substitute part must maintain identical electrical ratings, position count, pitch spacing, and mounting characteristics to ensure direct functional equivalence without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1976000000 is a direct functional equivalent to the 1976730000. Both parts are manufactured by Weidmüller within the Omnimate SC series and maintain identical electrical ratings, position configuration, pitch spacing, and mounting characteristics. The primary distinction is product status: the 1976730000 is obsolete while the 1976000000 is active.

Selection of the 1976000000 is supported by:

• Identical IEC and UL electrical ratings ensuring equivalent circuit performance
• Matching mechanical configuration (16 positions, 0.150" pitch, 135° orientation, through-hole mounting)
• Equivalent environmental compliance (UL94 V-0, RoHS compliant, -50°C to 120°C operating range)
• Active product status providing ongoing availability and supply chain continuity

The housing color difference (black versus orange) is a cosmetic variation that does not affect electrical or mechanical function. Packaging format (bulk for the substitute) may require adjustment to procurement and inventory procedures but does not impact component performance.

Frequently Asked Questions (FAQ)

Q: Can the 1976000000 be used as a direct replacement for the 1976730000 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent within the Omnimate SC series. They share identical position count, pitch spacing, orientation, current ratings (IEC: 17.5A; UL: 10A), voltage ratings (IEC: 320V; UL: 300V), and mounting method. No circuit redesign is required.

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

A: The 1976730000 is classified as obsolete, indicating it is no longer manufactured or supported by Weidmüller. The 1976000000 is active, meaning it is currently produced and available through standard distribution channels. For new designs or ongoing procurement, the active part number is recommended.

Q: Does the housing color difference affect compatibility?

A: No. The housing color change from black to orange is a cosmetic distinction only. It does not alter electrical performance, mechanical fit, or functional characteristics. Component selection may be based on visual identification requirements or internal documentation standards.

Q: Are there packaging considerations when switching to the 1976000000?

A: The 1976000000 is supplied in bulk packaging, whereas the original part number packaging format is not specified. Organizations should confirm bulk packaging compatibility with their receiving, storage, and assembly procedures. Electrical and mechanical specifications remain unchanged regardless of packaging format.

Q: What compliance certifications apply to both parts?

A: Both the 1976730000 and 1976000000 carry UL94 V-0 flammability rating, RoHS compliance, and REACH unaffected status. Operating temperature range is -50°C to 120°C for both parts. Compliance documentation should reference the specific part number used in production.
