Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5749925-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector style (D-Type)
• Connector type (Plug, Male Pins)
• Number of positions (68)
• Number of rows (2)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)
• Contact type (Signal)
• Current rating (1A)
• Voltage rating (30V)
• Operating temperature range (-55°C to 105°C)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line)
• Termination method (IDC, Ribbon Cable)
• Dielectric material (Thermoplastic)
• Material flammability rating (UL94 V-0)
• Series designation (AMPLIMITE .050 III)

The substitute part 5749621-7 maintains full equivalence across all critical electrical and mechanical parameters. Differences in shell material finish, packaging format, product status, and compliance certifications do not affect functional interchangeability in the connector interface.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The main part 5749925-5 carries an obsolete product status with limited inventory (662 pieces). The substitute part 5749621-7 is classified as active with significantly higher inventory availability (2100 pieces), ensuring long-term supply chain continuity for new designs and ongoing production requirements.

Compliance and Certification: The substitute part 5749621-7 is ROHS3 compliant, meeting current regulatory requirements for electronic components in restricted substance directives. The main part 5749925-5 carries a "Not applicable" RoHS status due to its obsolete classification. Both parts maintain equivalent UL94 V-0 flammability ratings and identical electrical specifications.

Functional Interchangeability: Both connectors are fully interchangeable at the interface level. The 5749621-7 substitute provides identical electrical performance, mechanical fit, and environmental operating characteristics. The addition of shielding features in the substitute part provides enhanced electromagnetic compatibility without compromising backward compatibility.

Selection Basis: For new applications and legacy system replacements, the TE Connectivity 5749621-7 is the appropriate selection due to active product status and current compliance certifications. For existing systems currently utilizing 5749925-5, direct substitution with 5749621-7 maintains full functional equivalence without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5749621-7 directly replace the 5749925-5 in existing applications?

A: Yes. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pin count (68 positions), pitch (0.050 x 0.100), current rating (1A), voltage rating (30V), operating temperature range (-55°C to 105°C), and IDC ribbon cable termination method. Direct substitution requires no design changes or reconfiguration.

Q: What is the difference between the shielded feature in 5749621-7 and the main part?

A: The 5749621-7 includes shielding, which provides additional electromagnetic interference (EMI) protection. This enhancement does not affect mechanical or electrical compatibility with the 5749925-5 interface. Shielding is a supplementary feature that improves signal integrity without altering connector geometry or pin configuration.

Q: Why is the 5749925-5 classified as obsolete?

A: Obsolete classification indicates the part is no longer in active production. The TE Connectivity 5749621-7 represents the current active equivalent within the AMPLIMITE .050 III series, offering the same functional performance with modern compliance certifications and improved availability.

Q: Are there packaging differences between these parts?

A: The 5749925-5 is supplied in standard packaging, while the 5749621-7 is supplied in bulk packaging. Packaging format does not affect connector performance or interchangeability. Bulk packaging typically accommodates higher-volume production requirements.

Q: Does the ROHS3 compliance of 5749621-7 affect compatibility with legacy systems?

A: No. ROHS3 compliance indicates adherence to current restricted substance directives and does not alter electrical or mechanical performance. The 5749621-7 is fully compatible with systems designed for the 5749925-5, including legacy equipment.

Q: What is the significance of the shell material difference (steel, tin-nickel plated in 5749621-7)?

A: Shell material and finish provide mechanical protection and corrosion resistance. The tin-nickel plated steel shell in the 5749621-7 offers enhanced durability compared to the main part. This difference does not affect connector interface compatibility or electrical performance.

Q: Can both parts be used interchangeably in the same ribbon cable assembly?

A: Yes. Both connectors accept identical IDC ribbon cable termination with 0.050 pitch and 0.100 row-to-row spacing. Ribbon cables terminated for the 5749925-5 are fully compatible with the 5749621-7 without modification.
