Substitute Part Grouping Explanation

Substitution of the DIN-048CSC-S3L-HM is determined by strict alignment of the following parameters:

Connector Type: Receptacle, Female Sockets (required match)
Number of Positions: 48 (required match)
Pitch: 0.100" (2.54mm) (required match)
Number of Rows: 3 (required match)
Mounting Type: Through Hole (required match)
Termination: Solder (required match)
Operating Temperature Range: -55°C to 125°C (required match or better)
Material Flammability Rating: UL94 V-0 (required match)
Moisture Sensitivity Level: 1 (required match)

Substitute parts are grouped into two categories:

Category A - Direct Style Match (C/2 Configuration): Parts with identical C/2 (1/2 C) style designation from TE Connectivity AMP Connectors (Eurocard series) and 3M. These provide the highest mechanical and electrical compatibility.

Category B - Compatible Style Variant (2C Configuration): The HARTING 09232486824 features a 2C style designation, which represents a different mechanical configuration within the DIN 41612 standard. While maintaining the same 48-position, 3-row, 2.54mm pitch geometry, the 2C style may have different keying or mounting characteristics and requires design verification for mechanical fit.

Category C - Header Configuration (Not Recommended for Direct Substitution): The HARTING 09281326902 is a header (male pins) connector, not a receptacle. This part is listed for reference only and is not suitable as a direct substitute for receptacle applications.

Engineering Selection Recommendations

Primary Substitutes (Recommended)

For new designs and procurement requiring RoHS compliance and active product status, select from:

5535070-5 (TE Connectivity): RoHS Compliant, Eurocard series, 3590 units in stock. Highest inventory availability.
5535070-4 (TE Connectivity): RoHS Compliant, Eurocard series, 1306 units in stock.
2-1393641-5 (TE Connectivity): ROHS3 Compliant, Eurocard series, 1199 units in stock.

These parts maintain C/2 style compatibility, gold contact finish, -55°C to 125°C operating range, and current RoHS compliance status.

Secondary Substitutes (Legacy/Non-Compliant)

For applications where RoHS compliance is not required or legacy inventory must be cleared:

535070-4, 535071-4, 535091-5 (TE Connectivity): All feature C/2 style, gold contacts, and -55°C to 125°C operation. RoHS status is not applicable or non-compliant. Use only in non-regulated applications.

Conditional Substitutes (Requires Design Verification)

09232486824 (HARTING): 2C style variant. Mechanical fit and keying compatibility must be verified before use. ROHS3 Compliant, 2662 units in stock.

Not Recommended for Direct Substitution

09281326902 (HARTING): Header (male pins) configuration. Intended for mating with receptacle connectors, not as a receptacle replacement.

Frequently Asked Questions (FAQ)

Q: Can I substitute the DIN-048CSC-S3L-HM with any 48-position DIN connector?

A: No. Substitution requires exact matching of connector type (receptacle vs. header), style designation (C/2 vs. 2C), pitch (2.54mm), row count (3), and mounting method (through-hole solder). Only parts meeting all these criteria are electrically and mechanically compatible.

Q: What is the difference between C/2 and 2C style designations?

A: Both are DIN 41612 standard configurations with 48 positions in 3 rows at 2.54mm pitch. The style designation indicates different mechanical keying and orientation characteristics. C/2 (1/2 C) and 2C are not interchangeable without design verification of mechanical fit and connector orientation.

Q: Are the TE Connectivity Eurocard series parts (535070, 535071, 535091, 5535070, 5536397) fully interchangeable?

A: All listed TE Connectivity parts share the same C/2 style, 48-position, 3-row, 2.54mm pitch configuration and are mechanically compatible. However, RoHS compliance status varies. For new designs, use ROHS3 Compliant variants (5535070-4, 5535070-5, 2-1393641-5, 5536397-5). Legacy parts (535070-4, 535070-5, 535071-4, 535091-5) are available for existing applications but are not RoHS compliant.

Q: Why is the HARTING 09281326902 listed if it is not a direct substitute?

A: This header connector is listed for reference in applications where a mating pair (receptacle + header) is required. It is not suitable as a replacement for the receptacle DIN-048CSC-S3L-HM.

Q: What is the current rating difference between the main part (3A) and substitute 5536397-5 (1.5A)?

A: The DIN-048CSC-S3L-HM is rated for 3A per contact, while 5536397-5 is rated for 1.5A. The 5536397-5 includes a Board Lock feature for mechanical retention. Use 5536397-5 only in applications where the 1.5A current rating is sufficient and board-level locking is required.

Q: Are all substitute parts available in bulk packaging?

A: Yes. All listed substitute parts are supplied in bulk packaging with current inventory levels ranging from 738 to 3590 units.

Q: What compliance certifications should I verify before selecting a substitute?

A: Verify RoHS status (RoHS Compliant, ROHS3 Compliant, or non-compliant), REACH status, and product status (Active). For regulated applications, use only ROHS3 Compliant or RoHS Compliant variants. The DIN-048CSC-S3L-HM is RoHS Compliant and REACH Unaffected.
