DCH-A-001 Equivalent & Substitute Parts

Part Overview

The DCH-A-001 is a 15 Position Two Piece Backshell Connector manufactured by Cinch Connectivity Solutions, featuring 180° cable exit orientation with shielding for D-Sub connectors. This component is classified as an accessory backshell designed for 15-position and HD26-position D-Sub connectors with Shell Size A compatibility.

The DCH-A-001 has reached obsolete product status. Locating equivalent or substitute parts is necessary to maintain system compatibility in applications where this connector backshell remains in use or to support legacy equipment requirements.

Substitute Part Grouping Explanation

Substitution of the DCH-A-001 is determined by strict equivalence across the following electrical and mechanical parameters:

• Number of Positions: 15
• Compatible Shell Size: A
• Compatible D-Sub Size: 15pos and HD26pos
• Cable Exit Angle: 180°
• Shielding Configuration: Shielded
• Cable Type: Round
• Primary Material: Plastic
• Plating Specification: Nickel over Copper
• Hardware Configuration: Mating Screws 4-40 with Assembly Hardware and Grommets
• Color: Silver
• Accessory Type: Two Piece Backshell

The DCH-A-003 meets all required parameters for direct substitution with the DCH-A-001, with the distinction that DCH-A-003 carries Active product status.

Parameter Comparison

Engineering Selection Recommendations

The DCH-A-003 is the direct functional equivalent to the obsolete DCH-A-001, maintaining identical electrical and mechanical specifications across all connector interface parameters. Both parts are manufactured by Cinch Connectivity Solutions and share the same series designation (DCH) and base product number (DCH-A).

The primary distinction between these parts lies in compliance status: DCH-A-003 is RoHS Compliant and carries Active product status, while DCH-A-001 is RoHS non-compliant and obsolete. For new designs or systems subject to RoHS regulatory requirements, DCH-A-003 is the appropriate selection. For legacy system support or where RoHS non-compliance is not a constraint, both parts provide equivalent functionality.

Both parts are classified under the same HTSUS and ECCN codes and present no regulatory differentiation outside of RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can DCH-A-003 be used as a direct replacement for DCH-A-001? A: Yes. The DCH-A-003 provides complete functional equivalence across all electrical and mechanical parameters, including connector position count, shell size compatibility, cable exit angle, shielding configuration, material composition, and hardware specifications.

Q: What is the primary reason to transition from DCH-A-001 to DCH-A-003? A: The DCH-A-001 is classified as obsolete, while DCH-A-003 maintains active product status. Additionally, DCH-A-003 is RoHS Compliant, whereas DCH-A-001 is RoHS non-compliant. For applications subject to RoHS regulations, DCH-A-003 is the required choice.

Q: Are there differences in packaging between these parts? A: Packaging differs slightly. DCH-A-001 is supplied in standard packaging, while DCH-A-003 is supplied in Bag packaging. This distinction does not affect connector functionality or compatibility.

Q: Will DCH-A-003 fit existing D-Sub connector assemblies designed for DCH-A-001? A: Yes. Both parts are compatible with 15-position and HD26-position D-Sub connectors with Shell Size A configuration. The mechanical interface, cable exit angle (180°), and mounting hardware (4-40 mating screws) are identical.

Q: Are there any technical limitations when substituting DCH-A-003 for DCH-A-001? A: No technical limitations exist. All functional and mechanical parameters remain equivalent. The substitution is complete within the constraints of RoHS compliance requirements applicable to the target application.
