TE Connectivity 747908-9 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747908-9 is a 15-position D-Sub plug connector with male pins, solder cup termination, and free-hanging (in-line) mounting configuration. This connector is part of the AMPLIMITE HD-20 series and features a tin-plated steel shell with gold-plated brass contacts. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where the original part is no longer available through standard procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 747908-9 is determined by strict equivalence across the following critical parameters: connector style (D-Sub), connector type (plug with male pins), number of positions (15), number of rows (2), shell size and layout (2 DA, A), termination method (solder cup), contact finish (gold), material flammability rating (UL94 V-0), and dielectric material (polybutylene terephthalate, glass filled).

The substitute parts are grouped into two categories based on mounting configuration differences:

Category 1: Free-Hanging (In-Line) Mounting Part 5-747908-2 maintains identical electrical and mechanical specifications to the main part, with the primary difference being packaging format (tray versus original packaging) and active product status with RoHS compliance.

Category 2: Panel Mount Configuration Parts 171-015-103L011, 171-015-103L021, and 171-015-103L031 are functionally equivalent in core electrical parameters but feature panel mount configuration instead of free-hanging mounting. These parts differ in flange feature location (cable side or mating side) and shell material finish (nickel plated versus tin plated). Current rating is higher at 5A compared to 3A for the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Free-Hanging In-Line Mounting)

Part 5-747908-2 is the direct functional equivalent to 747908-9. Both parts maintain identical connector specifications, electrical ratings, and mechanical dimensions. The primary distinction is product status: 5-747908-2 is active and RoHS compliant, whereas 747908-9 is obsolete. Selection of 5-747908-2 is appropriate for applications requiring the same free-hanging mounting configuration and is recommended for new designs and ongoing procurement where the original part is unavailable.

For Panel Mount Applications

Parts 171-015-103L011, 171-015-103L021, and 171-015-103L031 are suitable substitutes only when the application permits panel mount configuration. These NorComp parts are all active products with ROHS3 compliance. The selection among these three parts depends on flange feature location requirements: 171-015-103L011 and 171-015-103L021 feature cable-side flanges (differentiated by flange hole size), while 171-015-103L031 features a mating-side flange. All three NorComp parts support higher current ratings (5A versus 3A) and operate across a slightly narrower temperature range (-50°C to 100°C versus -55°C to 105°C).

Compliance Considerations

The obsolete status of 747908-9 necessitates substitution for new procurement. Part 5-747908-2 maintains TE Connectivity manufacturing continuity with RoHS compliance. NorComp alternatives provide ROHS3 compliance and are suitable for applications where panel mounting is acceptable. All substitute parts maintain UL94 V-0 flammability rating and gold contact finish specifications.

Frequently Asked Questions (FAQ)

Q: Can 5-747908-2 be used as a direct replacement for 747908-9?

A: Yes. Part 5-747908-2 is electrically and mechanically equivalent to 747908-9. Both are 15-position D-Sub plugs with male pins, solder cup termination, free-hanging mounting, 3A current rating, 250V voltage rating, and identical operating temperature range. The primary difference is packaging format and product status; 5-747908-2 is an active product with RoHS compliance.

Q: What is the key difference between the TE Connectivity and NorComp substitute options?

A: TE Connectivity part 5-747908-2 maintains free-hanging (in-line) mounting identical to the original 747908-9. NorComp parts (171-015-103L011, 171-015-103L021, 171-015-103L031) feature panel mount configuration. Selection depends on whether the application requires in-line or panel mount mounting style.

Q: Are the NorComp parts suitable for applications originally designed for 747908-9?

A: NorComp parts are suitable only if the application can accommodate panel mount configuration instead of free-hanging mounting. Electrical specifications are compatible: both maintain 15 positions, 2 rows, D-Sub shell size 2 (DA, A), solder cup termination, and gold contact finish. NorComp parts support higher current (5A versus 3A) and operate across a slightly narrower temperature range (-50°C to 100°C versus -55°C to 105°C).

Q: What is the difference between 171-015-103L011, 171-015-103L021, and 171-015-103L031?

A: All three NorComp parts are functionally equivalent 15-position D-Sub plugs with panel mount configuration. The distinction is flange feature location: 171-015-103L011 and 171-015-103L021 feature cable-side flanges (with different hole configurations), while 171-015-103L031 features a mating-side flange. Selection depends on the specific panel mount hole pattern required by the application.

Q: Are there temperature range differences between substitute options?

A: Yes. The original 747908-9 and TE Connectivity substitute 5-747908-2 operate across -55°C to 105°C. NorComp substitutes (171-015-103L011, 171-015-103L021, 171-015-103L031) operate across -50°C to 100°C. Applications requiring operation below -50°C or above 100°C must use 747908-9 or 5-747908-2.

Q: What is the current rating difference, and does it affect substitution?

A: The original 747908-9 and TE Connectivity substitute 5-747908-2 are rated for 3A. NorComp substitutes are rated for 5A. The higher NorComp rating does not prevent substitution in applications designed for 3A operation; the connector can safely handle lower current loads. Applications requiring current above 3A benefit from the higher NorComp rating.

Q: Are all substitute parts RoHS compliant?

A: Part 5-747908-2 is RoHS compliant. NorComp parts (171-015-103L011, 171-015-103L021, 171-015-103L031) are ROHS3 compliant. The original 747908-9 has not applicable RoHS status due to its obsolete classification. All substitutes meet current environmental compliance requirements.

Q: What is the difference in shell material finish between TE Connectivity and NorComp parts?

A: TE Connectivity parts (747908-9 and 5-747908-2) feature tin-plated steel shells. NorComp parts (171-015-103L011, 171-015-103L021, 171-015-103L031) feature nickel-plated steel shells. Both finishes provide corrosion resistance; selection depends on application environment and EMI shielding requirements.
