Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6STR-02-008 is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Voltage rating of 300V or higher
• Wire gauge accommodation of 12-22 AWG
• Operating temperature rating of 105°C or higher

Mechanical Compatibility:

• 2-circuit configuration
• 0.375" (9.53mm) pitch spacing
• Single row arrangement
• 3-wall barrier type
• Screw termination with captive plate (top)
• Solder turret termination (bottom)
• Through-hole mounting capability
• UL94 V-0 flammability rating

Functional Compatibility:

• Barrier block terminal block type
• Flange feature presence
• Chassis and panel mounting support

The substitute part T37028-02-0 meets all mechanical and electrical compatibility requirements, with the exception of current rating, which is specified at 20A versus the original 25A rating.

Parameter Comparison

Engineering Selection Recommendations

The T37028-02-0 from Curtis Industries serves as a functional equivalent to the obsolete 6STR-02-008. Both components share identical mechanical footprints, electrical ratings (with exception noted), and compliance certifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary design consideration is the current rating differential: the original 6STR-02-008 is rated at 25A, while the T37028-02-0 is rated at 20A. This reduction in current capacity must be evaluated against the actual circuit requirements. If the application operates at or below 20A, the substitute part provides full functional compatibility. If the application requires the full 25A capacity, alternative solutions must be pursued.

Both components maintain identical voltage ratings (300V), wire gauge accommodation (12-22 AWG), operating temperature (105°C), and flammability certification (UL94 V-0). The insulation material differs (polyamide versus polypropylene), but both materials satisfy the specified flammability and thermal requirements. The substitute part carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for modern procurement standards.

Frequently Asked Questions (FAQ)

Q: Can the T37028-02-0 be used as a direct replacement for the 6STR-02-008?

A: The T37028-02-0 provides mechanical and electrical compatibility for applications operating at 20A or below. The 5A reduction in current rating must be evaluated against circuit requirements. All other electrical and mechanical parameters are equivalent.

Q: What is the significance of the pitch specification in substitution?

A: The 0.375" (9.53mm) pitch determines the physical spacing between circuits and is critical for PCB layout compatibility. Both the original and substitute parts share identical pitch specifications, ensuring direct mounting compatibility without layout modifications.

Q: Are there differences in insulation material between these parts?

A: The 6STR-02-008 uses polyamide (PA) nylon insulation, while the T37028-02-0 uses polypropylene (PP) insulation. Both materials meet the UL94 V-0 flammability rating and 105°C operating temperature requirement. Material selection does not affect functional compatibility for the specified electrical parameters.

Q: What does the 3-wall barrier type indicate?

A: The 3-wall (tri) barrier configuration provides electrical isolation between the two circuits through three walls of insulation material. Both the original and substitute parts employ identical barrier architecture, ensuring equivalent electrical isolation performance.

Q: How does the obsolete status of the 6STR-02-008 affect procurement?

A: The obsolete classification indicates that TE Connectivity has discontinued production. The T37028-02-0 is in active production status, providing assured availability for new procurement and future system maintenance requirements.

Q: Are the solder turret terminations compatible with standard PCB assembly processes?

A: Both components feature identical solder turret bottom termination design. Compatibility with PCB assembly processes depends on the specific footprint and solder pad configuration of the target application, which must be verified against the mechanical drawings.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture sensitivity concerns. Both components carry this rating, eliminating moisture-related storage and handling restrictions during procurement and inventory management.
