Key Parameters

Substitute Part Grouping Explanation

Substitution of the ENVOY AC (100A) is based on the following critical parameters:

• Current Rating: 100A primary current capacity
• Type: Non-invasive solid core construction
• Mounting Configuration: Free hanging in-line installation
• Termination: Wire leads connection method
• Environmental Compliance: RoHS compliance and MSL rating

The CR8450-1000 manufactured by CR Magnetics Inc. satisfies these core substitution criteria. Both devices operate as 100A current sense transformers with solid core, non-invasive design and free-hanging in-line mounting. The CR8450-1000 maintains equivalent termination through wire leads and meets RoHS compliance requirements with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The CR8450-1000 is the designated substitute for the obsolete ENVOY AC (100A). Selection is based on:

• Product Status: The CR8450-1000 maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both devices meet RoHS requirements. The CR8450-1000 achieves ROHS3 compliance, representing current regulatory standards.
• Core Functional Equivalence: Both transformers operate as 100A solid core, non-invasive current sense devices with free-hanging in-line mounting and wire lead termination.
• Environmental Rating: Both devices carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: What makes the CR8450-1000 a suitable substitute for the ENVOY AC (100A)?

A: Both devices share identical current ratings (100A), transformer type (non-invasive solid core), mounting configuration (free-hanging in-line), and termination method (wire leads). Both maintain RoHS compliance and MSL 1 ratings, ensuring functional and environmental equivalence.

Q: Are there frequency range differences between these transformers?

A: Yes. The ENVOY AC (100A) operates across 2Hz to 50kHz, while the CR8450-1000 operates across 20Hz to 1kHz. Application frequency requirements must fall within the CR8450-1000 operating range for direct substitution.

Q: What is the DC resistance specification for the CR8450-1000?

A: The CR8450-1000 has a DC resistance of 21Ohm with a current ratio of 1000:1. These specifications are not provided for the ENVOY AC (100A).

Q: Does the CR8450-1000 come in different packaging options?

A: The CR8450-1000 is available in bulk packaging. Verify packaging requirements for your application before procurement.

Q: Are both devices RoHS compliant?

A: Yes. The ENVOY AC (100A) is RoHS Compliant, and the CR8450-1000 is ROHS3 Compliant, meeting current regulatory standards for hazardous substance restrictions.
