Substitute Part Grouping Explanation

The E-T-A 1620-1-5A qualifies as a direct substitute for the 1620-2-5A based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Current Rating: 5A (exact match required)
• Voltage Rating - DC: 14.5V (exact match required)
• Breaker Type: Thermal (exact match required)
• Actuator Type: Automatic Reset (exact match required)
• Number of Poles: 1 (exact match required)
• Mounting Type: Holder (exact match required)
• Series: 1620 (same product family)

Both parts maintain identical regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Parameter Comparison

Engineering Selection Recommendations

The E-T-A 1620-1-5A is a direct functional equivalent to the 1620-2-5A. Both parts are discontinued at DiGi Electronics and carry identical electrical ratings, mechanical specifications, and regulatory certifications. Selection between these parts should be based on packaging availability and inventory status. The 1620-1-5A is supplied in Box packaging, while the 1620-2-5A uses standard packaging. Both maintain ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the 1620-1-5A replace the 1620-2-5A in existing designs?

A: Yes. Both parts share identical electrical specifications (5A, 14.5V DC), thermal breaker type, automatic reset functionality, and single-pole holder mounting. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging. The 1620-1-5A is supplied in Box packaging, while the 1620-2-5A uses standard packaging. All electrical and mechanical parameters are identical.

Q: Are both parts compliant with current regulations?

A: Yes. Both the 1620-2-5A and 1620-1-5A are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards.

Q: Why is the 1620-2-5A discontinued?

A: Discontinuation at DiGi Electronics does not indicate a design flaw. The 1620-1-5A remains available as a direct substitute with identical specifications.

Q: Can I use a different current rating or voltage?

A: No. Substitution is valid only when current rating (5A) and voltage rating (14.5V DC) match exactly. Using different ratings will result in improper circuit protection.
