DIN-032CSB-S1L-HM Equivalent & Substitute Parts

Part Overview

The DIN-032CSB-S1L-HM is a 48-position DIN 41612 backplane connector receptacle manufactured by 3M. This through-hole solder-terminated connector features female sockets with gold contact finish and is designed for PCB mounting in industrial and telecommunications applications. The part maintains active product status with 778 units in current inventory. Equivalent and substitute parts are identified to support procurement flexibility, design revisions, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the DIN-032CSB-S1L-HM is determined by the following critical parameters:

Connector Type & Position Configuration: All substitute parts must be 48-position DIN 41612 receptacles with female sockets
Pitch & Row Configuration: 0.100" (2.54mm) pitch with 3-row arrangement is mandatory
Mounting & Termination: Through-hole solder termination required for PCB assembly compatibility
Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification required
Contact Finish: Gold plating specified for corrosion resistance and signal integrity

The identified substitutes meet these core electrical and mechanical parameters. Variations in loaded position count (32 vs. all positions), connector style designation (C/2 vs. 2C), and RoHS compliance status are noted but do not preclude functional substitution when design requirements permit.

Engineering Selection Recommendations

5650459-5 (TE Connectivity AMP Connectors) is the primary substitute option. This part maintains full electrical and mechanical compatibility with the DIN-032CSB-S1L-HM, including identical operating temperature range (-55°C ~ 125°C), gold contact finish, and RoHS compliance. The 32-position loaded configuration matches the original specification. Highest inventory availability (1169 units) supports procurement continuity.

09234486825 (HARTING) serves as a secondary substitute with all 48 positions loaded. This configuration provides expanded contact availability while maintaining core DIN 41612 compatibility, UL94 V-0 rating, and MSL 1 classification. Operating temperature range is not specified; design validation is required if thermal performance is critical. Mounting clips are included as an additional feature.

650459-5 (TE Connectivity AMP Connectors) is functionally equivalent but carries RoHS non-compliant status. This part is suitable only for applications where RoHS compliance is not mandated. All other electrical and mechanical parameters align with the original specification, including operating temperature range and gold contact finish.

Frequently Asked Questions (FAQ)

Q: Can 09234486825 be used as a direct replacement for DIN-032CSB-S1L-HM?

A: Yes, from a mechanical and electrical standpoint. The HARTING part maintains the same 48-position, 3-row DIN 41612 configuration with 0.100" pitch and through-hole solder termination. The key difference is that all 48 positions are loaded versus 32 in the original. Operating temperature range is not specified for this part; confirm thermal requirements with your design specifications.

Q: What is the difference between the two TE Connectivity options (5650459-5 and 650459-5)?

A: Both parts are mechanically and electrically identical with matching operating temperature ranges and gold contact finish. The primary distinction is RoHS compliance status: 5650459-5 is RoHS Compliant, while 650459-5 is RoHS non-compliant. Select based on your regulatory and procurement requirements.

Q: Does the loaded position count (32 vs. 48) affect substitution compatibility?

A: The loaded position count does not affect electrical or mechanical compatibility. The connector footprint and pitch remain identical. If your PCB design uses only 32 positions, both 32-loaded and 48-loaded variants will function correctly. Verify that your mating connector and PCB layout accommodate the specific loaded configuration.

Q: Are all substitute parts certified to the same flammability and moisture sensitivity standards?

A: Yes. All substitute parts carry UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification, matching the original DIN-032CSB-S1L-HM specification.

Q: Which substitute part should I select for new designs?

A: For new designs requiring RoHS compliance and maximum inventory availability, 5650459-5 is the recommended choice. It provides full specification alignment with the original part and the highest stock level (1169 units). If all 48 positions must be loaded and RoHS3 compliance is acceptable, 09234486825 is an alternative.
