Weidmüller 1646000000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1646000000 is a 10-position terminal block header with female sockets, 0.200" (5.08mm) pitch, designed for 90° right-angle through-hole mounting. This component is part of the Omnimate BL series and is rated for 12A (IEC) / 15A (UL) at 250V (IEC) / 300V (UL). The product status is obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance, repairs, and new designs requiring compatible interconnection solutions.

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1646000000 is determined by strict alignment of the following critical parameters:

Connector Configuration: 10 positions, 0.200" (5.08mm) pitch, female socket type
Mounting Geometry: 90° right-angle orientation, through-hole mounting
Electrical Performance: Current and voltage ratings must meet or exceed the original specification
Termination Method: Solder termination required for PCB integration
Safety Compliance: UL94 V-0 flammability rating for material safety

The On Shore Technology Inc. OSTV7105151 meets these substitution criteria. Both components share identical connector configuration (10 positions, 5.08mm pitch), mounting style (90° right-angle through-hole), termination method (solder), and flammability rating (UL94 V-0). The OSTV7105151 provides equivalent or superior electrical performance with 20A (UL) current rating and maintains 300V (UL) voltage rating.

Engineering Selection Recommendations

The On Shore Technology OSTV7105151 is a direct functional equivalent for the obsolete Weidmüller 1646000000. Selection should be based on the following factors:

Product Status: The Weidmüller component is obsolete, while the OSTV7105151 maintains active product status with confirmed inventory availability (1120 pcs in stock versus 714 pcs for the original).

Compliance and Certifications: Both components carry identical REACH Unaffected and EAR99 ECCN designations. The OSTV7105151 includes RoHS3 compliance certification, providing additional regulatory alignment for modern applications.

Electrical Performance: The OSTV7105151 exceeds the original specification with 20A (UL) current rating compared to 15A (UL), while maintaining the same 300V (UL) voltage rating. This provides design margin for existing applications.

Operating Temperature: The OSTV7105151 extends the operating range to -30°C ~ 105°C, compared to -20°C ~ 100°C for the original, offering broader environmental compatibility.

Physical Compatibility: Connector pitch, position count, orientation, and mounting method are identical. Retention latches are present on both components, ensuring consistent mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the OSTV7105151 directly replace the Weidmüller 1646000000 in existing designs?

A: Yes. Both components share identical connector configuration (10 positions, 5.08mm pitch), 90° right-angle through-hole mounting, solder termination, and UL94 V-0 flammability rating. The OSTV7105151 provides equal or superior electrical performance.

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

A: The primary differences are manufacturer, product status (obsolete vs. active), contact material (copper alloy vs. phosphor bronze), housing material (PBT vs. thermoplastic), and physical dimensions. The OSTV7105151 offers higher current rating (20A vs. 15A UL), extended temperature range (-30°C to 105°C vs. -20°C to 100°C), and RoHS3 compliance.

Q: Are there any compatibility concerns with PCB footprints?

A: Contact tail length and insulation height differ between the two components (0.177" / 10.31mm for Weidmüller vs. 0.138" / 8.61mm for OSTV7105151). PCB footprint verification is required to confirm mechanical fit, though both are designed for standard 5.08mm pitch through-hole mounting.

Q: What packaging options are available?

A: The Weidmüller 1646000000 is supplied in standard packaging. The OSTV7105151 is available in bulk packaging.

Q: Are both components RoHS compliant?

A: The OSTV7105151 is RoHS3 compliant. RoHS status for the Weidmüller component is not specified in the provided data.
