Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 870-03/002 is determined by the following critical parameters:

• Current Rating: 3 A (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Product Status: Active (ensures continued availability and support)
• Regulatory Compliance: ROHS3 Compliant and REACH status alignment

The identified substitute part 3EP3 meets these core substitution criteria. Both components share identical current ratings, chassis mount configuration, and active product status. The substitute maintains equivalent EMC/EMI filtering functionality within the specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 870-03/002 and 3EP3 maintain active product status, ensuring long-term availability and manufacturer support. Both components are ROHS3 compliant, meeting current environmental regulations. The 3EP3 substitute carries additional third-party certifications (CSA, UR, VDE) and specifies operating temperature range (-10°C ~ 40°C), providing documented performance boundaries. Selection between these parts should be based on application-specific requirements regarding voltage rating, termination style, and regulatory certification scope.

Frequently Asked Questions (FAQ)

Q: What makes the 3EP3 a valid substitute for the 870-03/002?

A: Both components share the critical substitution parameters: 3 A current rating and chassis mount configuration. Both maintain active product status and ROHS3 compliance, ensuring functional equivalence within the specified electrical and mechanical envelope.

Q: Are there differences in termination between these parts?

A: The 870-03/002 termination style is not specified in the available data. The 3EP3 uses wire leads for termination. Verify termination compatibility with your application circuit before selection.

Q: Does the 3EP3 operate at the same voltage as the 870-03/002?

A: The 870-03/002 rated AC voltage is not specified. The 3EP3 is rated for 250V AC at 50/60Hz. Confirm your application voltage requirements against the 3EP3 specification before substitution.

Q: What is the difference in REACH status between these parts?

A: The 870-03/002 is REACH Unaffected, while the 3EP3 is REACH Affected. Both comply with applicable regulations. REACH Affected status indicates the component contains substances of concern but remains compliant under REACH requirements.

Q: Can I use either part interchangeably in my design?

A: Both parts meet the core substitution criteria of 3 A current rating and chassis mount configuration. However, verify application-specific requirements including voltage rating, termination style, operating temperature range, and required certifications before final selection.
