Weidmüller 1753032001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1753032001 is a 7-position terminal block header with male pins, featuring a 4.6mm pitch and vertical through-hole mounting. This component is part of the Omnimate SL series and is designed for applications requiring reliable electrical connections with shrouded (4-side) protection. The part maintains Active product status and is RoHS compliant. Substitute parts may be required due to inventory availability, specific color requirements, or performance parameter variations in electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 1604520000 qualifies as a substitute for the 1753032001 based on the following critical parameters:

• Identical electrical connectivity: Both parts feature 7 positions with 4.6mm pitch spacing
• Matching mechanical form factor: Vertical through-hole orientation with male pins and 4-side shrouding
• Compatible electrical ratings: Both support IEC 320V operation; the substitute provides higher IEC current rating (17A vs. 15A)
• Equivalent safety certifications: Both achieve UL94 V-0 flammability rating and maintain RoHS compliance
• Identical series classification: Both belong to the Omnimate SL product line
• Matching termination method: Both use solder termination for PCB integration

Substitution is valid where the application requirements do not mandate the specific housing color (Black vs. Orange) or the exact contact tail length specifications (1.50mm vs. 3.20mm).

Parameter Comparison

Engineering Selection Recommendations

Both the 1753032001 and 1604520000 maintain Active product status within the Weidmüller Omnimate SL series and satisfy identical regulatory compliance requirements (RoHS, REACH, UL94 V-0). Selection between these parts should be based on:

Use 1753032001 when:

• Black housing color is specified in the design or assembly documentation
• The application requires LCP housing material with glass reinforcement
• The shorter contact tail length (1.50mm) is required for specific PCB stack-up configurations

Use 1604520000 when:

• Orange housing color is acceptable or preferred for circuit identification
• PBT housing material is compatible with the application environment
• The longer contact tail length (3.20mm) accommodates PCB thickness or assembly requirements
• The higher IEC current rating (17A) provides additional margin for the application

Both parts are electrically and mechanically compatible for standard 7-position, 4.6mm pitch terminal block applications operating within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can 1604520000 be used as a direct replacement for 1753032001 in existing designs?

A: The 1604520000 is electrically and mechanically compatible for applications where housing color and contact tail length are not critical design constraints. The substitute provides equivalent electrical performance and maintains identical safety certifications. PCB layout verification is required if the longer contact tail length (3.20mm vs. 1.50mm) affects component spacing or assembly clearances.

Q: What are the key differences between these two parts?

A: The primary differences are housing color (Black vs. Orange), housing material (LCP glass-filled vs. PBT), contact tail length (1.50mm vs. 3.20mm), and IEC current rating (15A vs. 17A). All other electrical, mechanical, and regulatory parameters are equivalent.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes. Both parts support IEC 320V operation. The 1604520000 provides a higher IEC current rating (17A vs. 15A), making it suitable for applications requiring the full 15A capacity of the 1753032001 and beyond. Both are rated for 10A under UL standards at 300V.

Q: Does the housing material difference affect performance?

A: Both LCP (glass-filled) and PBT housing materials achieve UL94 V-0 flammability rating and maintain equivalent ingress protection (IP10). Material selection depends on application-specific environmental requirements such as chemical exposure or thermal cycling conditions.

Q: What should be considered when switching from 1753032001 to 1604520000 in production?

A: Verify PCB layout compatibility with the longer contact tail length (3.20mm). Confirm that the orange housing color does not conflict with assembly or identification requirements. Both parts use identical solder termination and pitch spacing, so no changes to reflow profiles or assembly processes are required.
