Weidmüller 1635280000 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1635280000 is a 3-position terminal block header with male pins, shrouded on two sides, featuring a 0.200" (5.08mm) pitch and 135° through-hole mounting orientation. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 12A at 250V and UL ratings of 15A at 300V, with a temperature range of -20°C to 100°C.

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1635280000 is determined by the following critical parameters:

Position Count & Pitch: Both main and substitute parts must maintain 3 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
Pin Configuration: Male pins with 2-side shrouding are required to match the original connector interface.
Mounting Method: Through-hole mounting must be preserved for PCB integration.
Electrical Ratings: Substitute parts must meet or exceed UL ratings of 15A at 300V to maintain system safety margins.
Flammability Compliance: UL94 V-0 rating is mandatory for fire safety compliance.
Header Orientation: The 135° angle is a mechanical constraint specific to the original design; substitutes with different orientations (such as 45°) represent functional alternatives requiring board layout evaluation.

The On Shore Technology Inc. OSTVK035050 qualifies as a substitute based on matching position count, pitch, pin configuration, shrouding, mounting type, and electrical/flammability compliance, despite differing in header orientation (45° vs. 135°) and contact tail dimensions.

Engineering Selection Recommendations

The On Shore Technology Inc. OSTVK035050 is an active product suitable for substituting the obsolete Weidmüller 1635280000 based on the following criteria:

Electrical Equivalence: Both parts maintain identical UL current (15A) and voltage (300V) ratings, ensuring no degradation in electrical performance.
Mechanical Compatibility: Matching 3-position configuration at 0.200" (5.08mm) pitch with male pins and 2-side shrouding ensures connector interface compatibility.
Compliance Alignment: Both parts carry UL94 V-0 flammability certification and REACH Unaffected status, maintaining regulatory compliance.
Active Product Status: The OSTVK035050 is currently in active production, providing long-term availability and supply chain stability compared to the obsolete Weidmüller part.
Temperature Range Extension: The OSTVK035050 offers an extended operating temperature range (-30°C ~ 105°C) compared to the original (-20°C ~ 100°C), providing additional thermal margin.

Design Consideration: The header orientation differs (135° vs. 45°). PCB layout must be evaluated to confirm the 45° orientation of the substitute part is compatible with the intended mounting position and wire routing.

Frequently Asked Questions (FAQ)

Q: Can the On Shore OSTVK035050 directly replace the Weidmüller 1635280000 without PCB modification?

A: The OSTVK035050 matches all critical electrical and mechanical parameters (position count, pitch, pin type, shrouding, current/voltage ratings, and flammability compliance). However, the header orientation differs (45° vs. 135°). PCB compatibility depends on whether the board layout accommodates the different mounting angle. Physical verification of the mounting footprint is required.

Q: Are there electrical performance differences between these parts?

A: No. Both parts are rated for 15A at 300V under UL standards and carry UL94 V-0 flammability certification. The OSTVK035050 provides a wider operating temperature range (-30°C ~ 105°C vs. -20°C ~ 100°C), which represents an improvement over the original specification.

Q: What is the significance of the different contact tail lengths?

A: The Weidmüller part has a contact tail length of 0.177" (4.50mm), while the OSTVK035050 measures 0.161" (4.10mm). This 0.016" (0.40mm) difference affects solder joint geometry and PCB hole depth requirements. Verify that the PCB design accommodates the shorter tail length of the substitute part.

Q: Does the insulation height difference impact compatibility?

A: The OSTVK035050 has an insulation height of 0.571" (14.50mm) compared to the original 0.512" (13.00mm). This 0.059" (1.50mm) increase may affect clearance in confined mounting spaces. Confirm adequate vertical clearance in the application before substitution.

Q: Why is the Weidmüller part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The On Shore OSTVK035050 is an active product with ongoing manufacturing support, making it the appropriate choice for new designs and replacement applications.
