Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 1546306-3 qualifies as a direct substitute for the Weidmüller 62440 based on the following critical parameters:

• Circuit Configuration: Both parts provide 3 circuits with 6 wire entries across 2 rows
• Electrical Ratings: Identical 20A current rating and 300V voltage rating
• Wire Compatibility: Both accept 12-22 AWG wire gauge
• Termination Method: Both use screw-based top termination with closed bottom termination
• Barrier Construction: Both employ enclosed barrier block design
• Mounting: Both support chassis and panel mounting configurations
• Environmental Classification: Both rated MSL 1 (Unlimited) for moisture sensitivity
• Trade Compliance: Both classified under identical ECCN (EAR99) and HTSUS (8536.90.4000) codes

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1546306-3 is a functional equivalent for applications currently using the Weidmüller 62440. The substitute part maintains all critical electrical and mechanical parameters required for direct replacement.

The TE Connectivity part offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The component carries RoHS3 compliance and UL94 V-0 flammability rating, providing enhanced regulatory alignment for new designs. Operating temperature specification (-40°C ~ 120°C) is provided for the substitute part, supporting thermal performance documentation where required.

Physical differences include pitch specification (0.374" / 9.50mm for the substitute), barrier wall configuration (2 Wall Dual versus Enclosed), color variation (Black versus White), and insulation material composition (Thermoplastic versus Polyamide PA66). These differences do not affect functional substitution when mounting geometry and thermal environment are compatible with the specified pitch and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1546306-3 directly replace the Weidmüller 62440 in existing assemblies?

A: Yes. Both parts share identical circuit count (3), wire entry configuration (6), electrical ratings (20A, 300V), wire gauge acceptance (12-22 AWG), and termination method (screw-based). Mounting compatibility (chassis and panel) is equivalent. Physical mounting hole spacing should be verified against the specified 0.374" (9.50mm) pitch of the substitute part.

Q: What are the key differences between these two barrier block connectors?

A: The primary differences are product status (Weidmüller is obsolete; TE Connectivity is active), barrier wall design (Enclosed versus 2 Wall Dual), insulation material (Polyamide PA66 versus Thermoplastic), color (White versus Black), and operating temperature documentation (-40°C ~ 120°C for the substitute). Electrical and mechanical performance parameters remain equivalent.

Q: Are there compliance or certification differences?

A: The TE Connectivity substitute carries RoHS3 compliance and UL94 V-0 flammability rating. The Weidmüller part lists REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) trade classification. Compliance requirements for your specific application should be evaluated against these certifications.

Q: Does the pitch specification affect substitution?

A: The TE Connectivity part specifies 0.374" (9.50mm) pitch. The Weidmüller part does not provide pitch specification in available documentation. Mounting hole center-to-center distance should be verified for mechanical compatibility in your assembly before substitution.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
