Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 747948-5 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 1-747948-8 maintains identical specifications in the following key areas:

Electrical Compatibility:

• 25 position configuration with 2-row layout
• Shell size 3 (DB, B) D-Sub format
• 250V voltage rating
• Gold contact finish with flash thickness
• Phosphor bronze contact material
• Support for 22-26 AWG wire gauge

Mechanical Compatibility:

• Male pin plug connector type
• Cable-side male jackscrew (4-40) flange
• Steel shell with tin plating
• Free hanging in-line mounting
• IDC and discrete wire termination support
• Shielded design with backshell, cover, and grounding indents

Environmental & Compliance:

• UL94 V-0 flammability rating
• Operating temperature range -55°C ~ 105°C
• Moisture Sensitivity Level 1 (Unlimited)
• ECCN EAR99 classification

The substitute part differs only in product status (Active versus Obsolete) and RoHS compliance certification, with no impact on functional or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criterion: Product Status

The TE Connectivity 1-747948-8 is the direct substitute for the obsolete 747948-5. Both parts are manufactured by TE Connectivity within the same AMPLIMITE HDE-20 series and share identical electrical and mechanical specifications. The substitute part is classified as Active, ensuring continued availability and manufacturing support.

Compliance Advantage

The 1-747948-8 carries ROHS3 compliance certification, whereas the 747948-5 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies regulatory requirements without functional or performance compromise.

Functional Equivalence

Both parts support identical termination methods (IDC and discrete wire), wire gauges (22-26 AWG), voltage ratings (250V), and operating temperature ranges (-55°C ~ 105°C). Mechanical interchangeability is complete, including jackscrew flange configuration, shell dimensions, and shielding features.

Packaging Consideration

The substitute part is supplied in bulk packaging, whereas the main part uses standard packaging. This difference affects logistics and inventory management but does not impact component performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1-747948-8 directly replace the 747948-5 in existing designs?

A: Yes. The 1-747948-8 is electrically and mechanically equivalent to the 747948-5. Both connectors feature identical 25-position D-Sub configuration, shell size 3 (DB, B), male pin plug type, and support for IDC and discrete wire termination with 22-26 AWG wire gauge. Mounting, flange configuration, and shielding are identical.

Q: What is the primary reason for substitution?

A: The 747948-5 is classified as obsolete. The 1-747948-8 is an active product from the same manufacturer and series, ensuring continued availability and manufacturing support. Both parts are functionally identical.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 1-747948-8 carries ROHS3 compliance certification. The original 747948-5 is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part satisfies regulatory requirements.

Q: Are there differences in electrical performance between the two parts?

A: No. Both parts share identical voltage ratings (250V), contact materials (phosphor bronze with gold flash finish), and operating temperature ranges (-55°C ~ 105°C). Current rating varies by wire gauge for both parts.

Q: What is the difference in packaging between these parts?

A: The 747948-5 uses standard packaging, while the 1-747948-8 is supplied in bulk packaging. This affects order quantities and inventory management but does not impact component specifications or performance.

Q: Are both parts suitable for IDC termination?

A: Yes. Both the 747948-5 and 1-747948-8 support IDC (Insulation Displacement Contact) and discrete wire termination methods. Wire gauge compatibility is identical at 22-26 AWG.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across the temperature range of -55°C to 105°C, with UL94 V-0 flammability rating for the shell material.

Q: Can these connectors be used in shielded applications?

A: Yes. Both parts feature shielded design with backshell, cover, and grounding indents, suitable for applications requiring electromagnetic interference protection.
