Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 6WWR-03-006 is determined by strict alignment of the following parameters:

• Circuit Configuration: 3 circuits with 0.375" (9.53mm) pitch spacing
• Electrical Performance: 25A current rating and 300V voltage rating
• Termination Method: Screw termination with captive plate on top connection
• Wire Compatibility: 12-22 AWG wire gauge acceptance
• Mechanical Form Factor: Through-hole mounting, single-row configuration
• Barrier Isolation: 3-wall barrier type for circuit separation

The Molex 0387244903 meets all core electrical and mechanical substitution criteria. Differences in bottom termination method (PC Pin versus Wire Wrap), insulation material composition, and operating temperature range do not preclude functional equivalence in applications where the top-side screw termination and electrical ratings are the primary design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 6WWR-03-006 and Molex 0387244903 are Active product status components with full regulatory compliance. The TE Connectivity part carries RoHS Compliant certification, while the Molex equivalent is ROHS3 Compliant. Both components are classified as REACH Unaffected or Vendor Undefined, with EAR99 export classification and identical HTSUS commodity codes.

Selection between these parts is determined by application-specific requirements regarding bottom termination method. The TE Connectivity 6WWR-03-006 features Wire Wrap bottom termination, suitable for applications requiring wire-to-board connections. The Molex 0387244903 provides PC Pin bottom termination for printed circuit board mounting. Both parts maintain identical electrical performance (25A, 300V), wire gauge compatibility (12-22 AWG), and mechanical form factor (3-circuit, 0.375" pitch, through-hole, single-row configuration).

Operating temperature range differs between the two parts: TE Connectivity operates to 105°C, while Molex operates within -40°C to 100°C. Insulation material composition also differs (Thermoplastic versus PBT), though both materials meet the specified electrical and mechanical requirements for this product category.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387244903 directly replace the TE Connectivity 6WWR-03-006 in existing designs?

A: Direct replacement depends on bottom termination requirements. If the design uses Wire Wrap connections, the TE Connectivity part is specified. If PC Pin connections are acceptable or required, the Molex part is functionally equivalent. Both parts share identical top-side screw termination, electrical ratings (25A, 300V), circuit count (3), pitch (0.375"), and wire gauge compatibility (12-22 AWG).

Q: Are there differences in circuit isolation between these parts?

A: Both parts feature 3-wall (Tri) barrier type construction, providing equivalent circuit isolation. Barrier configuration is identical between the TE Connectivity 6WWR-03-006 and Molex 0387244903.

Q: What is the significance of the different insulation materials?

A: The TE Connectivity part uses Thermoplastic insulation, while the Molex part uses Polybutylene Terephthalate (PBT). Both materials are suitable for the specified electrical environment (300V, 25A). Material selection does not affect electrical performance or mechanical compatibility in applications within the rated voltage and current parameters.

Q: How do the operating temperature ranges affect substitution?

A: The TE Connectivity 6WWR-03-006 operates to 105°C, while the Molex 0387244903 operates within -40°C to 100°C. Applications requiring sustained operation above 100°C require the TE Connectivity part. Applications operating within -40°C to 100°C accept either part.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 6WWR-03-006 is RoHS Compliant. The Molex 0387244903 is ROHS3 Compliant. Both meet current RoHS requirements and are suitable for applications with RoHS compliance mandates.

Q: What is the difference between Wire Wrap and PC Pin termination?

A: Wire Wrap termination (TE Connectivity 6WWR-03-006) connects directly to wire leads. PC Pin termination (Molex 0387244903) connects to printed circuit board pads. Selection depends on the application's connection method: wire-to-board or board-to-board.

Q: Do both parts have identical moisture sensitivity?

A: Yes. Both the TE Connectivity 6WWR-03-006 and Molex 0387244903 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the screw materials and finishes identical?

A: Yes. Both parts feature steel terminal screws with Zinc, Clear Chromate finish, ensuring equivalent corrosion resistance and electrical conductivity.
