Engineering Selection Recommendations
Primary Recommendation: 5745396-2
The 5745396-2 from TE Connectivity AMP Connectors is the direct active equivalent of the obsolete 745396-2. This part maintains identical electrical and mechanical specifications across all critical parameters: 15-position D-Sub receptacle, female sockets, through-hole right-angle mounting, mating-side female screwlock fastening, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The primary distinction is RoHS compliance status. Selection of 5745396-2 eliminates compatibility risk and maintains original design intent.
Secondary Recommendations: Amphenol ICC Cross-Manufacturer Alternatives
Cross-manufacturer alternatives from Amphenol ICC satisfy the core D-Sub 15-position receptacle requirements with through-hole right-angle solder termination. These parts are active production components with RoHS compliance certification.
L77DA15S1AONVF provides the closest functional match among Amphenol ICC options, featuring mating-side female screwlock fastening identical to the original 745396-2. This part supports 7.5A current rating and 300V voltage rating, exceeding original specifications. Operating temperature range extends to 125°C.
DAPV15S565GTLF offers enhanced electrical performance with 7.5A per contact current rating and 1000V voltage rating. This part includes mating-side female screwlock fastening and board lock features. Backset spacing differs at 0.406" (10.30mm) versus original 0.318" (8.08mm).
DA15S565CTLF provides a cost-effective alternative with housing/shell unthreaded flange configuration. Current rating is 5A, which is below the original 6A specification. Backset spacing is 0.409" (10.40mm).
L77DA15SAM4 and L77DA15SAZ4 feature mounting brackets and support 7.5A current rating with 300V voltage rating. Both use housing/shell unthreaded flange configuration. Backset spacing is 0.319" (8.10mm), matching the original specification.
L77DA15S1AON and L77DA15S1BON provide 7.5A current rating and 300V voltage rating with housing/shell unthreaded flange configuration. Backset spacing is 0.406" (10.30mm).
L177DFAH15SAM4 supports panel mount and through-hole right-angle mounting with board-side flange fastening. Current rating is 7.5A with 300V voltage rating. This part includes mounting brackets.
L77DA15SCVF2 features free-hanging in-line mounting with solder cup termination rather than through-hole solder termination. This configuration is suitable for cable assembly applications rather than PCB mounting.
Selection among alternatives depends on specific application requirements regarding flange configuration, backset spacing, current and voltage ratings, and mounting method.
Frequently Asked Questions (FAQ)
Q: Can the 5745396-2 directly replace the obsolete 745396-2 in existing designs?
A: Yes. The 5745396-2 maintains identical electrical and mechanical specifications with the 745396-2 across all critical parameters: 15-position D-Sub receptacle, female sockets, through-hole right-angle mounting, mating-side female screwlock fastening, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The only difference is RoHS compliance status. Direct substitution is supported without design modification.
Q: What is the significance of flange feature differences among substitute parts?
A: Flange feature determines the fastening mechanism and mounting interface. The original 745396-2 uses mating-side female screwlock (4-40) fastening, which secures the connector at the mating interface. Alternatives with housing/shell unthreaded flange configuration lack threaded fastening at the mating side. Parts with board-side flange fastening secure the connector to the PCB rather than at the mating interface. Selection must match the intended mounting and fastening requirement of the application.
Q: How does backset spacing affect connector compatibility?
A: Backset spacing is the distance from the rear of the connector shell to the solder termination points. The original 745396-2 specifies 0.318" (8.08mm). Alternatives vary between 0.319" (8.10mm), 0.406" (10.30mm), and 0.409" (10.40mm). Significant differences in backset spacing affect PCB layout and component placement. Parts with matching or near-matching backset spacing (within 0.001") are preferred for direct substitution. Larger variations require PCB redesign.
Q: Are Amphenol ICC parts electrically compatible with the TE Connectivity 745396-2?
A: Amphenol ICC D-Sub 15-position receptacles are electrically compatible with the 745396-2 in terms of connector style, position count, and signal contact configuration. However, electrical performance parameters differ. Most Amphenol ICC alternatives support higher current ratings (7.5A versus 6A) and voltage ratings (300V to 1000V versus 125V). These enhancements provide design margin but do not prevent substitution in applications requiring the original specifications.
Q: What is the difference between solder termination and solder cup termination?
A: Solder termination (through-hole) is designed for direct PCB mounting with solder joints formed through plated holes. Solder cup termination is designed for cable assembly, where individual wires are inserted into cup-shaped contact receptacles and soldered. The L77DA15SCVF2 uses solder cup termination and free-hanging in-line mounting, making it unsuitable for PCB-mounted applications. Selection must match the intended termination method.
Q: Does RoHS compliance status affect functional compatibility?
A: RoHS compliance status does not affect functional compatibility or electrical performance. The original 745396-2 is RoHS non-compliant, while all active substitute parts are RoHS compliant. RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers) in the component composition. Selection of RoHS-compliant alternatives supports regulatory compliance in new designs and procurement requirements.
Q: Which substitute part is recommended for new designs?
A: The 5745396-2 is recommended for new designs as the direct active equivalent of the obsolete 745396-2. This part maintains identical specifications and eliminates compatibility risk. If design requirements permit enhanced electrical performance, L77DA15S1AONVF from Amphenol ICC provides mating-side female screwlock fastening with 7.5A current rating and 300V voltage rating. For cost-sensitive applications, L77DA15SAM4 or L77DA15SAZ4 offer 7.5A current rating with mounting bracket features at reduced cost.
Q: How do contact material differences affect connector performance?
A: The original 745396-2 uses phosphor bronze contacts. Substitute parts use either phosphor bronze, brass, or copper alloy contacts. Contact material affects electrical conductivity, corrosion resistance, and mechanical durability. Phosphor bronze provides superior spring characteristics and corrosion resistance. Brass and copper alloy contacts are cost-effective alternatives with adequate performance for standard signal applications. Material selection does not prevent substitution but may affect long-term reliability in harsh environments.
Q: Are there inventory considerations when selecting substitute parts?
A: Yes. Inventory availability varies among substitute parts. The 5745396-2 has 2161 pieces in stock. Amphenol ICC alternatives range from 643 to 1152 pieces in stock. For applications requiring immediate delivery or large quantities, inventory status should be verified with the component supplier. The original 745396-2 has 778 pieces available as new original stock but is classified as obsolete, indicating limited future availability.
