Parameter Comparison

Engineering Selection Recommendations

Primary Selection: DBM25PA208

The DBM25PA208 is the recommended choice for new designs and applications requiring active production support. This connector offers superior current handling capacity at 7.5A and an extended operating temperature range of -55°C to 125°C, providing greater operational margin for demanding environments. The part maintains active product status with confirmed inventory availability of 669 units.

Substitute Selection: 172-025-112R021

The 172-025-112R021 serves as a functional substitute for legacy systems or applications where the reduced current rating of 5A and narrower operating temperature range (-50°C to 100°C) are acceptable. This part is classified as obsolete, indicating limited future availability. Selection of this substitute should be restricted to replacement scenarios in existing installations where the electrical and thermal requirements do not exceed the specified limits.

Both parts achieve UL94 V-0 flammability compliance and maintain RoHS compliance status, meeting environmental and safety regulatory requirements. The choice between these connectors should be determined by application current requirements, operating temperature demands, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can 172-025-112R021 be used as a direct replacement for DBM25PA208 in all applications?

A: No. The substitute part has a lower current rating (5A versus 7.5A) and a narrower operating temperature range (-50°C to 100°C versus -55°C to 125°C). Substitution is only appropriate when the application requirements fall within these reduced specifications.

Q: What is the significance of the product status difference?

A: DBM25PA208 is active in production with ongoing manufacturer support. The substitute part 172-025-112R021 is obsolete, meaning the manufacturer no longer produces it. For new designs, the active part is strongly preferred to ensure long-term supply chain stability.

Q: Are there differences in contact material that affect performance?

A: Yes. DBM25PA208 uses copper alloy contacts while 172-025-112R021 uses brass contacts. Both materials are suitable for signal applications with gold plating. The copper alloy in the primary part may offer slightly different electrical characteristics, though both meet the specified gold contact finish requirement.

Q: How do the shell material finishes compare?

A: DBM25PA208 features yellow chromate plated zinc, while 172-025-112R021 uses tin plating. Both provide corrosion protection suitable for industrial environments. The choice depends on specific environmental exposure and compatibility requirements with mating connectors.

Q: What is the difference between solder cup and solder termination?

A: Both parts use solder-based termination. The DBM25PA208 specifies solder cup termination, while 172-025-112R021 uses general solder termination. Both methods are compatible with standard PCB assembly processes.

Q: Does the flange feature difference affect panel mounting?

A: Both parts support panel mounting. DBM25PA208 has an unthreaded housing/shell flange, while 172-025-112R021 includes board side (4-40) mounting. The mounting method should be verified against your specific panel configuration and installation requirements.
