Engineering Selection Recommendations

Primary Substitute: DCH-B-003

The DCH-B-003 is the direct equivalent for the obsolete DCH-B-001. All electrical and mechanical parameters are identical, ensuring functional compatibility in existing designs and assemblies.

Compliance Advantage: The DCH-B-003 carries RoHS Compliant certification, whereas the DCH-B-001 is RoHS non-compliant. For new designs or systems subject to RoHS requirements, the DCH-B-003 is the appropriate selection.

Product Status: The transition from Obsolete (DCH-B-001) to Active (DCH-B-003) ensures long-term availability and supply chain continuity.

Packaging Consideration: The DCH-B-003 is supplied in Bag packaging. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can DCH-B-003 be used as a direct replacement for DCH-B-001 in existing assemblies?

A: Yes. The DCH-B-003 matches all critical electrical and mechanical parameters of the DCH-B-001, including position count, shell size, cable exit angle, shielding configuration, plating specification, and mating hardware. Direct substitution is supported.

Q: What is the primary difference between DCH-B-001 and DCH-B-003?

A: The DCH-B-001 is Obsolete and RoHS non-compliant. The DCH-B-003 is Active and RoHS Compliant. Both parts are functionally equivalent.

Q: Are there any compatibility restrictions when substituting DCH-B-003 for DCH-B-001?

A: No compatibility restrictions exist. Both parts are designed for 25-position and HD44-position D-Sub connectors with Shell Size B and support identical cable configurations.

Q: Does packaging differ between these parts?

A: Yes. The DCH-B-001 packaging is not specified in available documentation. The DCH-B-003 is supplied in Bag packaging. Confirm packaging requirements for your procurement process.

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance is relevant only if your application or regulatory environment requires it. The DCH-B-003 is RoHS Compliant; the DCH-B-001 is not. For new designs subject to RoHS regulations, the DCH-B-003 is required.

Q: What is the inventory status for these parts?

A: DCH-B-001: 1025 Pcs New Original In Stock. DCH-B-003: 1019 Pcs New Original In Stock. Both parts are currently available.
