Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 748826-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5748826-1 qualifies as a direct equivalent based on the following matching criteria:

Electrical Parameters: Both parts maintain identical voltage rating (125V), current rating (6A), contact material (brass), and contact finish specification (gold, 30.0µin thickness).

Mechanical Parameters: Both connectors share the same connector style (D-Sub), connector type (plug with male pins), position count (25), row configuration (2), shell size and layout (3, DB, B), mounting type (through hole, right angle), and backset spacing (0.590").

Environmental and Compliance Parameters: Both parts operate across the identical temperature range (-55°C to 105°C), maintain the same flammability rating (UL94 V-0), and share equivalent moisture sensitivity classification (MSL 1, Unlimited).

Termination and Packaging: Both parts utilize solder termination and are supplied in tray packaging.

The primary distinction between the main part and substitute lies in RoHS compliance status and inventory availability, not in functional or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 748826-1 and 5748826-1 are functionally and mechanically equivalent D-Sub connectors suitable for direct substitution in applications requiring 25-position, right-angle solder-terminated connectors.

Primary Part Selection (748826-1): This part is appropriate for applications where RoHS compliance is not a requirement or where legacy component specifications must be maintained. The part maintains active production status with adequate inventory availability.

Substitute Part Selection (5748826-1): This part is appropriate for applications subject to ROHS3 compliance mandates or where enhanced environmental regulatory alignment is required. The substitute part maintains active production status with higher inventory availability (1722 pieces versus 906 pieces), providing improved procurement flexibility and reduced lead time risk.

Both parts carry identical electrical ratings (125V, 6A), thermal operating range (-55°C to 105°C), and flammability certification (UL94 V-0). Selection between these parts should be based on regulatory compliance requirements specific to the end application and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Are the 748826-1 and 5748826-1 connectors physically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shell size (3, DB, B), mounting type (through hole, right angle), position count (25), row configuration (2), and backset spacing (0.590"). They are direct physical substitutes.

Q: What is the primary difference between these two parts?

A: The primary difference is RoHS compliance status. The 5748826-1 is ROHS3 compliant, while the 748826-1 is not applicable for RoHS classification. All electrical, mechanical, and thermal specifications are identical.

Q: Can I use the 5748826-1 in an application originally designed for the 748826-1?

A: Yes. The 5748826-1 maintains all functional and physical equivalence to the 748826-1. Applications requiring ROHS3 compliance should specify the 5748826-1. Applications without RoHS requirements can use either part.

Q: Are the contact finishes identical between these parts?

A: Yes. Both parts feature gold-plated brass contacts with identical finish thickness of 30.0µin (0.76µm).

Q: What is the current and voltage rating for both connectors?

A: Both connectors are rated for 6A current and 125V voltage. Operating temperature range is -55°C to 105°C for both parts.

Q: Are these connectors suitable for solder termination?

A: Yes. Both parts are designed for solder termination and are supplied in tray packaging suitable for automated assembly processes.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should I select for new designs?

A: For new designs, the 5748826-1 is recommended due to ROHS3 compliance alignment with current regulatory standards and higher inventory availability. For legacy system maintenance or applications without RoHS requirements, either part is suitable.
