Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 3-128-197 are identified based on electrical and mechanical parameter equivalence. The substitution criteria include:

• Breaker Type: Thermal operation
• Current Rating: 10A
• Voltage Ratings: 277 V AC and 32 V DC
• Mounting Configuration: Panel mount with rocker actuator
• Pole Configuration: Single pole (1P)
• Regulatory Compliance: CCC, CE, cURus, and VDE certifications
• Environmental Compliance: ROHS3 Compliant status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. No deviations in electrical performance or mechanical interface are present between the main part and identified substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 3-128-197 and 3-128-198 are active production parts with full regulatory compliance across CCC, CE, cURus, and VDE certification bodies. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance restrictions.

Selection between these parts is based on inventory availability and procurement lead time. The 3-128-198 carries higher stock levels at 1123 units compared to 1027 units for the 3-128-197. Both parts are functionally identical for thermal circuit breaker applications requiring 10A protection at 277 V AC or 32 V DC with panel mount rocker actuator configuration.

Frequently Asked Questions (FAQ)

Q: Can the 3-128-198 be used as a direct replacement for the 3-128-197?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (10A, 277 V AC, 32 V DC), thermal breaker operation, single pole rocker actuator, and panel mount configuration. All regulatory certifications and compliance statuses are identical.

Q: Are there any differences in mechanical interface between these parts?

A: No. Both parts share identical mounting type (panel mount), actuator type (rocker), and packaging (box). Physical installation and electrical connection are equivalent.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the 3-128-197 and 3-128-198 hold CCC, CE, cURus, and VDE certifications. Both are ROHS3 compliant and REACH unaffected.

Q: What is the basis for substitution between these parts?

A: Substitution is based on complete equivalence across all provided electrical parameters (current rating, voltage ratings, breaker type), mechanical parameters (mounting type, actuator type, pole configuration), and regulatory compliance status.

Q: Are there inventory considerations for part selection?

A: The 3-128-198 has higher current inventory (1123 units) compared to the 3-128-197 (1027 units). Procurement decisions may factor inventory availability for lead time optimization.
