DIN-120RPC-DPS-HM Equivalent & Substitute Parts

Part Overview

The DIN-120RPC-DPS-HM is a 120-position DIN connector plug manufactured by 3M, designed for backplane applications with male pins and gold plating. This component features through-hole mounting with press-fit termination and operates across an industrial temperature range of -55°C to 125°C. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DIN-120RPC-DPS-HM is determined by strict alignment of the following parameters:

• Connector type (Plug, Male Pins)
• Position count (120 positions)
• Pitch specification (0.100" / 2.54mm)
• Row configuration (3 rows)
• Style designation (R)
• Mounting method (Through Hole)
• Termination type (Press-Fit)
• Contact finish (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)

The substitute part 5650921-5 from TE Connectivity AMP Connectors meets all these critical parameters, enabling direct functional equivalence for PCB-level backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

The DIN-120RPC-DPS-HM is classified as obsolete. The substitute part 5650921-5 maintains active product status with TE Connectivity AMP Connectors and provides full parameter alignment across all critical electrical and mechanical specifications.

Both components achieve RoHS compliance (the substitute meets ROHS3 standard) and carry UL94 V-0 flammability certification. The identical pitch, row configuration, position count, and termination method ensure mechanical and electrical interchangeability in backplane connector applications.

Selection between these parts should be based on availability, supply chain considerations, and any application-specific requirements related to connector series compatibility (DIN 41612 versus Eurocard series designation).

Frequently Asked Questions (FAQ)

Q: Can 5650921-5 be used as a direct replacement for DIN-120RPC-DPS-HM?

A: Yes. Both connectors share identical electrical and mechanical parameters: 120 positions, 0.100" pitch, 3-row configuration, Style R, through-hole mounting, press-fit termination, gold contact finish, and -55°C to 125°C operating range. Both meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications.

Q: What is the difference between the DIN 41612 and Eurocard series designations?

A: Both designations refer to standardized 0.100" pitch connector families. The series designation reflects the standardization body or connector family lineage. Functionally, connectors from both series with matching position counts, pitch, and row configurations are mechanically and electrically compatible.

Q: Are there any compliance differences between the two parts?

A: The DIN-120RPC-DPS-HM is RoHS Compliant. The 5650921-5 is ROHS3 Compliant, representing a more recent compliance standard. Both meet the same flammability and moisture sensitivity requirements.

Q: What mounting considerations apply to both parts?

A: Both connectors use through-hole mounting with press-fit termination. PCB design and layout requirements remain identical. Hole spacing, diameter, and plating specifications should reference the respective manufacturer datasheets for precise dimensional requirements.

Q: Is current rating a substitution criterion?

A: The DIN-120RPC-DPS-HM specifies a 3A current rating. The 5650921-5 does not provide a current rating specification in the available data. Application-specific current requirements should be evaluated against manufacturer documentation for the substitute part.
