Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-1437662-1 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Terminal block type: Barrier block configuration
• Number of circuits: 7 circuits
• Pitch spacing: 0.375" (9.53mm)
• Voltage rating: 300V minimum
• Wire gauge compatibility: 12-22 AWG
• Bottom termination: PC pin
• Barrier type: 3 Wall (Tri)
• Operating temperature: 105°C
• Flammability rating: UL94 V-0

Substitution Categories:

Direct Equivalent (6PCV-07-006): Maintains all critical electrical and mechanical parameters with active product status. Current rating is rated higher at 25A, providing enhanced capacity within the same form factor and pitch specification.

Similar Equivalent (T37111-07-0): Maintains all critical electrical and mechanical parameters with active product status from an alternative manufacturer (Curtis Industries). Mounting type includes both chassis/panel and through-hole options, providing application flexibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer):

The 6PCV-07-006 is the primary substitute for the obsolete 1-1437662-1. Both components are manufactured by TE Connectivity AMP Connectors and share identical electrical specifications, pitch, circuit count, and termination compatibility. The 6PCV-07-006 carries active product status, ensuring ongoing availability and supply chain support. The increased current rating of 25A provides additional design margin compared to the original 20A specification. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification.

For Alternative Manufacturer Selection:

The T37111-07-0 from Curtis Industries provides an equivalent barrier block terminal connector with matching electrical and mechanical parameters. This component maintains the same 20A current rating, 300V voltage specification, and 0.375" pitch as the original part. The T37111-07-0 offers expanded mounting flexibility with both chassis/panel and through-hole mounting options. This part carries active product status and ROHS3 compliance with REACH unaffected designation.

Compliance Considerations:

Both substitute parts maintain UL94 V-0 flammability ratings and operate within the 105°C temperature specification. RoHS compliance is confirmed for both alternatives, supporting regulatory requirements for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 6PCV-07-006 directly replace the 1-1437662-1 in existing designs?

A: Yes. The 6PCV-07-006 maintains identical pitch spacing (0.375"), circuit count (7), voltage rating (300V), wire gauge compatibility (12-22 AWG), and termination types (screw with captive plate top, PC pin bottom). The increased current rating of 25A provides enhanced capacity within the same physical form factor. PCB footprints and mounting hole patterns are compatible.

Q: What is the primary difference between the 6PCV-07-006 and T37111-07-0?

A: The 6PCV-07-006 is manufactured by TE Connectivity AMP Connectors and features screw termination without a captive plate. The T37111-07-0 is manufactured by Curtis Industries and includes screw termination with a captive plate, matching the original 1-1437662-1 design. Both maintain identical electrical specifications and pitch. The T37111-07-0 offers additional mounting flexibility with chassis/panel mounting options.

Q: Are there packaging differences between these substitute parts?

A: The 1-1437662-1 original specification does not define packaging type. The 6PCV-07-006 is supplied in bulk packaging. The T37111-07-0 is also supplied in bulk packaging. Packaging specifications should be confirmed with the supplier for production requirements.

Q: Do all three parts meet the same regulatory standards?

A: All three parts maintain UL94 V-0 flammability ratings and operate at 105°C. The 1-1437662-1 and T37111-07-0 are ROHS3 compliant. The 6PCV-07-006 is RoHS compliant. All parts carry EAR99 ECCN classification and 8536.90.4000 HTSUS code. The T37111-07-0 carries REACH unaffected status.

Q: What is the significance of the captive plate feature?

A: The captive plate on the 1-1437662-1 and T37111-07-0 provides mechanical retention of the screw during assembly and maintenance operations. The 6PCV-07-006 features standard screw termination without this retention feature. Design requirements should determine whether this feature is necessary for the application.

Q: Can the 25A-rated 6PCV-07-006 be used in applications originally designed for 20A?

A: Yes. The 6PCV-07-006 is rated for 25A, which exceeds the original 20A specification. This provides additional design margin and current capacity. The connector maintains all other electrical and mechanical parameters identical to the original specification.

Q: What mounting options are available with the T37111-07-0?

A: The T37111-07-0 supports both chassis/panel mounting and through-hole mounting configurations. The original 1-1437662-1 and 6PCV-07-006 are specified for through-hole mounting only. The expanded mounting flexibility of the T37111-07-0 may provide additional application options.
