DMH-E-001 Equivalent & Substitute Parts

Part Overview

The DMH-E-001 is a 9-position two-piece backshell connector manufactured by Cinch Connectivity Solutions. This shielded D-Sub accessory features a 180° cable exit configuration and is compatible with both 9-position and HD15-position D-Sub connectors. The part is currently active in production with 1147 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original manufacturer part is unavailable or when alternative sourcing is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMH-E-001 is determined by strict equivalence across the following critical parameters:

• Number of Positions: Must be 9
• Compatible Shell Size: Must be E
• Compatible D-Sub Size: Must support 9pos and HD15pos
• Cable Exit Angle: Must be 180°
• Shielding Configuration: Must be shielded
• Accessory Type: Must be two-piece backshell
• Cable Type: Must be round
• Primary Material: Must be metal
• Hardware Inclusion: Must include assembly hardware and grommets
• Mating Feature: Must use 4-40 mating screws

The substitute part 970-009-030R121 meets all these criteria and is therefore classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the DMH-E-001 and 970-009-030R121 are active production parts with equivalent mechanical and electrical specifications. Selection between these parts should be based on:

Compliance Certifications: The DMH-E-001 carries RoHS Compliant status, while the 970-009-030R121 carries ROHS3 Compliant status. Both are REACH Unaffected and classified under identical ECCN and HTSUS codes, indicating equivalent regulatory standing.

Material Specification: The 970-009-030R121 specifies nickel over copper plating, whereas the DMH-E-001 plating is not specified. This difference does not affect functional equivalence for standard D-Sub backshell applications.

Inventory Availability: The 970-009-030R121 has significantly higher inventory (10,078 units) compared to the DMH-E-001 (1,147 units), which may influence sourcing decisions based on lead time requirements.

Packaging: The DMH-E-001 is supplied in unspecified packaging, while the 970-009-030R121 is supplied in bulk packaging. Packaging selection should align with assembly and handling requirements.

Frequently Asked Questions (FAQ)

Q: What makes 970-009-030R121 a valid substitute for DMH-E-001?

A: The 970-009-030R121 meets all critical electrical and mechanical parameters: 9-position configuration, E shell size compatibility, 180° cable exit, shielded design, two-piece backshell construction, round cable type, metal construction with 4-40 mating screws, and identical regulatory classifications (ECCN EAR99, HTSUS 8538.90.8180).

Q: Are there differences in plating between these parts?

A: The DMH-E-001 does not specify plating information, while the 970-009-030R121 specifies nickel over copper plating. Both parts are zinc-based metal construction and maintain equivalent shielding and mechanical performance.

Q: Do both parts support the same D-Sub connector sizes?

A: Yes. Both the DMH-E-001 and 970-009-030R121 are compatible with 9-position and HD15-position D-Sub connectors with E shell size.

Q: What is the difference in RoHS compliance between these parts?

A: The DMH-E-001 is RoHS Compliant, while the 970-009-030R121 is ROHS3 Compliant. Both meet current regulatory requirements and are REACH Unaffected.

Q: Can these backshells be used interchangeably in existing assemblies?

A: Yes, provided the assembly accommodates the specified packaging format. The 970-009-030R121 is supplied in bulk packaging, while the DMH-E-001 packaging is not specified. Mechanical and electrical performance are equivalent.

Q: What is the cable exit configuration for both parts?

A: Both parts feature a 180° cable exit angle, meaning the cable exits perpendicular to the connector mating face.
