Substitute Part Grouping Explanation

Substitute parts for the DIN-048CPC-SR1-HM are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Connector Type: Plug with male pins (required for mating with receptacle connectors)
Position Count: 48 positions (electrical and mechanical interface requirement)
Pitch: 0.100" (2.54mm) (PCB layout and contact spacing requirement)
Row Configuration: 3 rows (physical form factor requirement)
Style: C/2 (1/2 C) (DIN 41612 standard compliance)
Mounting: Through hole, right angle (PCB integration method)
Termination: Solder (connection method to PCB)
Contact Finish: Gold (electrical conductivity and corrosion resistance)
Flammability: UL94 V-0 (material safety requirement)

All substitute parts listed maintain these core parameters. Variations in insulation material, RoHS compliance status, and REACH classification do not affect electrical or mechanical substitutability for this connector category.

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity AMP Connectors)

The TE Connectivity AMP parts 5650916-5, 5650478-5, 5650948-5, 650916-5, 650478-5, and 650948-5 are direct functional equivalents to the DIN-048CPC-SR1-HM. All maintain identical electrical and mechanical specifications across the critical substitution parameters. Selection among these parts should be based on:

Inventory availability: 5650916-5 offers the highest stock level (80,198 units)
RoHS compliance requirements: 5650916-5, 5650478-5, and 650478-5 carry ROHS3 compliance; 5650948-5 carries RoHS compliance; 650916-5 and 650948-5 are RoHS non-compliant
REACH status: 650478-5 is REACH Unaffected; 5650916-5, 5650478-5, 5650948-5, 650916-5, and 650948-5 are REACH Affected or Vendor Undefined
Board Lock feature: 5650916-5 and 650916-5 include board lock functionality; others do not

Alternative Substitute (Hirose Electric)

The PCN10A-48P-2.54DS(72) from Hirose Electric is classified as a header connector rather than a DIN plug. While it maintains the same position count, pitch, row configuration, and mounting method, the connector type differs. This part is suitable only when the design permits header-to-receptacle mating instead of plug-to-receptacle mating. The operating temperature range is reduced to -55°C ~ 85°C and current rating is 2A compared to the 3M part's 3A rating.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the DIN-048CPC-SR1-HM?

A: The TE Connectivity AMP plug connectors (5650916-5, 5650478-5, 5650948-5, 650916-5, 650478-5, 650948-5) are direct mechanical and electrical substitutes. The Hirose PCN10A-48P-2.54DS(72) is a header connector and is not interchangeable unless your design accommodates header-to-receptacle mating.

Q: What is the difference between a DIN plug and a header connector?

A: A DIN plug is designed to mate with a DIN receptacle connector. A header connector is designed to mate with a cable-mounted connector or receptacle. The physical form factors differ, and they are not compatible with each other.

Q: Do RoHS compliance differences affect substitutability?

A: RoHS compliance status does not affect the electrical or mechanical function of the connector. Selection should be based on your application's regulatory requirements and end-market restrictions.

Q: Why does the Hirose part have a lower operating temperature maximum?

A: The PCN10A-48P-2.54DS(72) is rated to -55°C ~ 85°C, while the DIN-048CPC-SR1-HM is rated to -55°C ~ 125°C. If your application requires operation above 85°C, the Hirose part is not suitable.

Q: What does the Board Lock feature mean on some TE Connectivity parts?

A: Board Lock is a mechanical feature that provides additional retention of the connector to the PCB. It does not affect electrical performance but provides enhanced mechanical stability. Parts with this feature are 5650916-5 and 650916-5.

Q: Can I mix different substitute parts in the same assembly?

A: Yes, all TE Connectivity AMP plug connectors listed are functionally equivalent and can be used together in the same assembly. The Hirose header connector should not be mixed with DIN plug connectors unless your design specifically accommodates both connector types.
