Part Overview
The DIN-048RPC-S1-HM is a 48-position DIN 41612 backplane connector plug with male pins, gold contact finish, and through-hole solder termination manufactured by 3M. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and new designs requiring compatible interconnect solutions. The part operates across a wide temperature range (-55°C to 125°C) with a 3A current rating and UL94 V-0 flammability compliance.

Substitute Part Grouping Explanation
Substitution for the DIN-048RPC-S1-HM is determined by strict alignment of the following electrical and mechanical parameters:
Primary Substitution Criteria:
- Series: DIN 41612 (mandatory for mechanical and electrical compatibility)
- Number of Positions: 48 (exact match required)
- Pitch: 0.100" (2.54mm) (exact match required)
- Number of Rows: 3 (exact match required)
- Mounting Type: Through Hole (exact match required)
- Termination: Solder (exact match required)
- Contact Finish: Gold or Gold-Palladium (acceptable alternatives)
- Operating Temperature Range: Must encompass or match -55°C to 125°C
- Current Rating: Must meet or exceed 3A
- Material Flammability Rating: UL94 V-0 (mandatory for compliance)
Connector Type Consideration: The main part is a Plug with male pins. Direct substitutes must also be Plugs with male pins. Header connectors (male pins on the connector body) are mechanically and electrically incompatible with plug-type receptacles and are listed for reference only.
Substitute Parts Identified:
- TE Connectivity AMP Connectors 2-1393659-6 (Plug, R/2 style, Eurocard series)
- TE Connectivity AMP Connectors 3-1393659-9 (Plug, R/2 style, Eurocard series)

Engineering Selection Recommendations
Primary Substitutes (Direct Compatibility):
The TE Connectivity AMP Connectors parts 2-1393659-6 and 3-1393659-9 are direct functional equivalents to the DIN-048RPC-S1-HM. Both parts meet all critical electrical and mechanical parameters: 48-position DIN 41612 plug configuration, R/2 style, 0.100" pitch, 3-row layout, through-hole solder termination, and identical operating temperature range (-55°C to 125°C). Both parts carry active product status and ROHS3 compliance, providing long-term availability and regulatory alignment superior to the obsolete 3M part.
The contact finish difference (Gold-Palladium versus pure Gold) is acceptable within DIN 41612 specifications and does not compromise electrical performance or mating compatibility. Both TE Connectivity parts are packaged in trays and maintain UL94 V-0 flammability ratings.
Secondary Reference Parts (Not Direct Substitutes):
HARTING parts 09281482902, 09281486902, 09281486903, 09281486985, 09283486902, and 09283486903 are DIN 41612 series connectors but are Header-type connectors (male pins on the connector body) rather than Plug-type connectors. These parts are mechanically and electrically incompatible with the DIN-048RPC-S1-HM plug configuration and cannot serve as direct substitutes. They are listed in the provided substitute data but do not meet the core substitution criterion of matching connector type.
HARTING parts 09455511124 and 09455511126 are modular RJ45 Ethernet connectors and belong to a different connector category (Modular Connectors, not Backplane Connectors). These parts are not applicable for DIN 41612 backplane applications.
Frequently Asked Questions (FAQ)
Q: Can HARTING Header connectors (09281482902, 09281486902, etc.) be used as substitutes for the DIN-048RPC-S1-HM?
A: No. The DIN-048RPC-S1-HM is a Plug connector with male pins. HARTING parts listed are Header connectors with male pins on the connector body. These are mechanically and electrically incompatible. Plugs mate with receptacles; Headers mate with sockets. Using a Header in place of a Plug will result in connection failure.
Q: What is the difference between Gold and Gold-Palladium contact finishes in DIN 41612 connectors?
A: Both finishes provide equivalent electrical performance and mating compatibility within DIN 41612 specifications. Gold-Palladium is a flash coating over a base metal, while pure Gold is a thicker deposit. For the operating conditions specified (-55°C to 125°C, 3A current), both finishes meet contact resistance and durability requirements. Selection between them is based on application-specific corrosion resistance needs and cost considerations.
Q: Are the TE Connectivity parts 2-1393659-6 and 3-1393659-9 interchangeable?
A: Yes. Both parts are 48-position DIN 41612 R/2 style plugs with identical electrical and mechanical specifications. The primary difference is packaging (both in trays) and inventory levels. Either part can be selected based on availability and lead time.
Q: Why is the DIN-048RPC-S1-HM marked as obsolete?
A: The 3M part has reached end-of-life status. TE Connectivity AMP Connectors maintains active production of functionally equivalent DIN 41612 48-position plugs, making the TE parts the recommended long-term solution for new designs and ongoing system support.
Q: Does the RoHS3 compliance of substitute parts affect compatibility with the original 3M part?
A: No. ROHS3 compliance is a regulatory requirement indicating the part contains no restricted substances. This does not affect electrical or mechanical compatibility. Systems using the obsolete RoHS-compliant 3M part can be serviced with ROHS3-compliant TE Connectivity substitutes without functional impact.
Q: What mounting considerations apply when replacing the DIN-048RPC-S1-HM?
A: All identified substitute parts use through-hole solder termination on a 0.100" (2.54mm) pitch grid. PCB footprints designed for the DIN-048RPC-S1-HM will accommodate the TE Connectivity substitutes without modification. Verify PCB hole spacing and solder pad layout match the 48-position, 3-row DIN 41612 standard before assembly.
