Substitute Part Grouping Explanation

The 2037-25-C5 has one direct equivalent substitute: the 2037-25-B5. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 250 V
• Impulse Discharge Current (8/20µs): 5000A (5kA)
• Tolerance: ±15%
• Number of Poles: 2
• Fail Short: No
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, Radial Bend
• Series: 2037 (Base Product Number)

The 2037-25-B5 meets all electrical and mechanical specifications required for direct substitution. The primary distinction is product status: the 2037-25-C5 is obsolete, while the 2037-25-B5 is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The 2037-25-B5 is the direct equivalent for the obsolete 2037-25-C5. Both parts share identical electrical ratings, mechanical specifications, and regulatory classifications. The 2037-25-B5 is currently in active production status with confirmed inventory availability (1112 pcs), making it the appropriate selection for new designs and field replacements. Both parts carry identical compliance designations (RoHS non-compliant, REACH Affected, EAR99 classification), so no additional regulatory considerations apply to the substitution.

Frequently Asked Questions (FAQ)

Q: Can the 2037-25-B5 be used as a direct replacement for the 2037-25-C5?

A: Yes. The 2037-25-B5 is electrically and mechanically identical to the 2037-25-C5 across all specified parameters, including voltage rating, discharge current capacity, tolerance, pole configuration, and physical package. The only difference is product status: the 2037-25-B5 is active and available.

Q: Are there any differences in packaging between these parts?

A: Both parts use identical Axial Cylinder, Radial Bend package configuration. The 2037-25-C5 was supplied in standard packaging, while the 2037-25-B5 is available in bulk packaging. This distinction does not affect electrical or mechanical compatibility.

Q: Do both parts have the same regulatory compliance status?

A: Yes. Both the 2037-25-C5 and 2037-25-B5 share identical compliance designations: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8536.30.8000.

Q: Why is the 2037-25-C5 marked as obsolete?

A: The 2037-25-C5 has reached end-of-life status. The 2037-25-B5 remains in active production and serves as the current equivalent for this specification.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: 250V DC spark-over voltage, 5000A (5kA) impulse discharge current, ±15% tolerance, 2-pole configuration, through-hole mounting, and Axial Cylinder, Radial Bend package type.
