Weidmüller 1753034001 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1753034001 is a 7-position terminal block header with male pins, shrouded on 4 sides, designed for vertical through-hole mounting with 0.138" (4.60mm) pitch spacing. This component is part of the Omnimate SL series and maintains Active product status. Substitute parts may be required due to packaging availability, inventory constraints, or specific application requirements where alternative housing materials or electrical ratings are acceptable within design parameters.

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1753034001 with part number 1604520000 is permissible based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters (Substitution Basis):

• Identical number of positions: 7
• Identical pitch spacing: 0.138" (4.60mm)
• Identical header orientation: Vertical
• Identical mounting type: Through Hole
• Identical termination style: Solder
• Identical type configuration: Header, Male Pins, Shrouded (4 Side)
• Identical voltage rating - IEC: 320 V
• Identical voltage rating - UL: 300 V
• Identical current rating - UL: 10 A
• Identical operating temperature range: -50°C ~ 100°C
• Identical contact material: Copper Alloy
• Identical material flammability rating: UL94 V-0
• Identical RoHS compliance status: RoHS Compliant
• Identical product status: Active

Differing Parameters (Non-Critical for Substitution):

• Packaging format (Tape & Reel vs. Bulk)
• Housing material (LCP Glass Filled vs. PBT)
• Color (Black vs. Orange)
• Current rating - IEC (15A vs. 17A)
• Contact tail length (0.059" vs. 0.126")
• Insulation height (0.435" vs. 0.437")

The substitute part 1604520000 maintains functional and electrical equivalence for applications requiring the specified 7-position, 4.60mm pitch terminal block header configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 1753034001 and 1604520000 maintain Active product status and full compliance with RoHS and UL94 V-0 flammability requirements. Selection between these parts should be based on:

Packaging Requirements: The 1753034001 is supplied in Tape & Reel format, suitable for automated assembly processes. The 1604520000 is supplied in Bulk packaging, appropriate for manual assembly or lower-volume applications.

Electrical Performance: Both parts satisfy the specified voltage and current requirements for UL applications (300 V, 10 A). The 1604520000 provides a higher IEC current rating (17A vs. 15A), making it suitable for applications requiring enhanced current capacity within the same voltage envelope.

Material Considerations: The 1753034001 uses LCP glass-filled housing, while the 1604520000 uses PBT housing. Both materials meet UL94 V-0 flammability standards. Housing material selection should align with specific environmental exposure, chemical resistance, and mechanical stress requirements of the application.

Physical Dimensions: Minor variations exist in contact tail length and insulation height. These differences do not affect electrical function but may impact PCB layout and mechanical clearance considerations.

Frequently Asked Questions (FAQ)

Q: Can the 1604520000 directly replace the 1753034001 in existing designs?

A: Yes, the 1604520000 provides functional and electrical equivalence. Both parts share identical position count, pitch spacing, voltage ratings, and UL current specifications. Differences in packaging format, housing material, and color do not affect electrical performance or mechanical compatibility in standard through-hole PCB applications.

Q: What is the significance of the different housing materials (LCP vs. PBT)?

A: Both materials meet UL94 V-0 flammability requirements. LCP glass-filled housing (1753034001) offers superior dimensional stability and higher temperature performance. PBT housing (1604520000) provides good chemical resistance and cost efficiency. Material selection should be based on specific environmental conditions and mechanical requirements of the application.

Q: Why does the 1604520000 have a higher IEC current rating (17A vs. 15A)?

A: The higher IEC current rating reflects the electrical capability of the 1604520000 design. Both parts maintain identical UL current ratings (10A), which is the controlling specification for UL-compliant applications. The IEC rating difference does not affect substitution suitability for applications designed to UL standards.

Q: Does packaging format affect component performance?

A: No. Tape & Reel (1753034001) and Bulk (1604520000) packaging formats do not affect electrical or mechanical performance. Packaging selection is driven by assembly process requirements: Tape & Reel is optimized for automated pick-and-place assembly, while Bulk packaging is suitable for manual assembly or lower-volume production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS compliance status and UL94 V-0 flammability ratings. Both are Active products with full regulatory compliance for their respective applications.
