Weidmüller 1638350000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1638350000 is a 10-position terminal block plug with female sockets, 5.00mm pitch, and 270° free-hanging configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 15A at 400V and UL ratings of 10A at 300V, with screw-clamping termination suitable for wire gauges 12-26 AWG (0.5-2.5mm²).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1638350000 is determined by the following critical parameters:

• Position Count & Pitch: 10 positions with 5.00mm (0.197") or 5.08mm (0.200") pitch spacing
• Connector Type: Plug configuration with female sockets
• Wire Entry Orientation: 270° free-hanging (in-line) mounting
• Electrical Ratings: Minimum UL 15A at 300V or IEC 15A at 400V capability
• Termination Method: Screw-based clamping mechanism
• Wire Compatibility: Support for 12-26 AWG wire gauge range
• Flammability Compliance: UL94 V-0 material rating
• Contact Finish: Tin plating

The substitute parts listed below meet these core substitution criteria. Minor variations in pitch tolerance (5.00mm vs. 5.08mm), housing material composition, contact material (copper alloy vs. phosphor bronze), and color do not prevent functional substitution in applications where mechanical and electrical compatibility is maintained.

Parameter Comparison

Engineering Selection Recommendations

Molex 0395332010 is suitable for applications requiring active product support and compliance documentation. This part maintains 10-position configuration with 5.08mm pitch spacing, which represents a 0.08mm deviation from the original 5.00mm specification. The part carries ROHS3 compliance and operates across -40°C to 105°C. UL current rating of 15A exceeds the original 10A specification. Wire gauge compatibility (12-26 AWG) matches the original part. Inventory availability is confirmed at 1044 units.

TE Connectivity 1-284040-0 provides exact pitch matching (5.00mm) to the original Weidmüller component, eliminating mechanical tolerance concerns. This part is active and ROHS3 compliant with extended operating temperature range (-40°C to 110°C). UL current rating of 15A and voltage rating of 300V meet or exceed original specifications. Wire gauge support extends to 12-30 AWG, providing broader compatibility. Inventory availability is confirmed at 1227 units. Housing color is green rather than black.

Both substitute parts satisfy the core electrical, mechanical, and compliance requirements of the obsolete Weidmüller 1638350000. Selection between alternatives depends on specific application constraints regarding pitch tolerance, operating temperature range, wire gauge requirements, and connector color specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395332010 be used as a direct replacement despite the 5.08mm pitch versus 5.00mm pitch?

A: The 0.08mm pitch difference represents a 1.6% tolerance deviation. Compatibility depends on the mating header or socket design. If the receiving connector accommodates 5.08mm pitch spacing, the Molex part functions as a substitute. If the application requires exact 5.00mm pitch matching, the TE Connectivity 1-284040-0 is the appropriate selection.

Q: What is the significance of the different termination styles (Clamping Yoke vs. Rising Cage Clamp)?

A: Both termination methods are screw-based clamping mechanisms. The Clamping Yoke (Tension Sleeve) used in the original Weidmüller part and the Rising Cage Clamp used in substitute parts both secure wire conductors through screw tightening. The mechanical interface differs, but both achieve equivalent electrical and mechanical retention for the specified wire gauge ranges.

Q: Are there wire gauge compatibility concerns when substituting?

A: The original Weidmüller part supports 12-26 AWG (0.5-2.5mm²). The Molex substitute maintains identical 12-26 AWG support. The TE Connectivity substitute extends support to 12-30 AWG (0.05-3mm²), providing broader compatibility without reducing support for the original range. No compatibility loss occurs with either substitute.

Q: Does the housing material change affect performance?

A: The original Weidmüller part uses Polybutylene Terephthalate (PBT). Both substitutes use Polyamide (PA66), Nylon 6/6. Both materials carry UL94 V-0 flammability ratings and operate within the specified temperature ranges. Material composition does not affect electrical performance or mechanical function for this application category.

Q: What compliance certifications apply to the substitute parts?

A: The Molex 0395332010 carries ROHS3 compliance and REACH Affected status. The TE Connectivity 1-284040-0 carries ROHS3 compliance with REACH status listed as Vendor Undefined. Both parts maintain UL94 V-0 flammability ratings equivalent to the original component. Verify specific compliance requirements against your application standards before final selection.

Q: Is inventory availability a consideration for part selection?

A: Current inventory levels are confirmed at 1044 units for the Molex part and 1227 units for the TE Connectivity part. Both alternatives maintain adequate stock for procurement. The original Weidmüller part shows 964 units in inventory despite obsolete status.
