Parameter Comparison

Engineering Selection Recommendations

For Through Hole Mounting Applications:

The Amphenol ICC (FCI) Delta D series parts (D25P91C6PX00LF, D25P91C6GV00LF, D25P91C4GV00LF) are direct functional equivalents to the TE Connectivity 5748146-4. All three parts maintain Active product status, RoHS compliance, and UL94 V-0 flammability rating. These substitutes provide extended operating temperature ranges (-55°C ~ 125°C versus -55°C ~ 105°C) and specified current ratings (5A per contact) and voltage ratings (300V), offering enhanced electrical performance documentation.

D25P91C6PX00LF is the closest match, featuring identical flange configuration (Housing/Shell 4-40) and grounding indents without board lock features. This part is suitable for applications requiring direct pin-for-pin compatibility with the original TE Connectivity connector.

D25P91C6GV00LF and D25P91C4GV00LF include board lock features and mating-side female screwlock flanges, providing additional mechanical retention. These variants are appropriate for applications requiring enhanced mechanical stability during mating cycles.

For Panel Mount Applications:

The NorComp 191-025-123R001 serves as an alternative for applications where panel mounting is required. This part maintains 25-position configuration, press-fit termination, and gold-plated contacts. The panel mount configuration and unthreaded flange distinguish this part from through-hole variants. ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C) are documented.

Compliance and Certification:

All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance status, meeting regulatory requirements equivalent to the original part. The Amphenol ICC parts provide REACH Unaffected status, while the NorComp part is REACH Affected. All parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.

Frequently Asked Questions (FAQ)

Q: Can D25P91C6PX00LF be used as a direct replacement for 5748146-4 in through-hole applications?

A: Yes. Both parts share identical 25-position configuration, through-hole mounting, press-fit termination, and Housing/Shell (4-40) flange design. The D25P91C6PX00LF provides equivalent electrical and mechanical functionality with extended operating temperature range and specified current/voltage ratings.

Q: What is the difference between D25P91C6PX00LF, D25P91C6GV00LF, and D25P91C4GV00LF?

A: All three parts are 25-position D-Sub plugs with through-hole mounting and press-fit termination. D25P91C6PX00LF features Housing/Shell flange without board lock. D25P91C6GV00LF and D25P91C4GV00LF include board lock features and mating-side female screwlock flanges. The board lock variants provide enhanced mechanical retention during connector mating. Contact finish thickness differs: D25P91C6PX00LF and D25P91C6GV00LF specify 30.0µin (0.76µm), while D25P91C4GV00LF specifies flash thickness.

Q: Is the NorComp 191-025-123R001 compatible with through-hole PCB designs?

A: No. The NorComp 191-025-123R001 is configured for panel mount applications, not through-hole mounting. This part is suitable only for applications where the connector is mounted directly to an enclosure or panel. For through-hole PCB mounting, use D25P91C6PX00LF, D25P91C6GV00LF, or D25P91C4GV00LF.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS compliance (D25P91 series: RoHS Compliant; NorComp 191-025-123R001: ROHS3 Compliant). The original TE Connectivity 5748146-4 is RoHS Compliant.

Q: What is the operating temperature difference between the original part and substitutes?

A: The TE Connectivity 5748146-4 operates from -55°C to 105°C. All Amphenol ICC substitutes (D25P91 series) and the NorComp 191-025-123R001 operate from -55°C to 125°C, providing a 20°C extended upper temperature limit.

Q: Do the substitute parts have specified electrical ratings?

A: The Amphenol ICC D25P91 series parts specify 5A per contact current rating and 300V voltage rating. The original TE Connectivity 5748146-4 does not provide specified current or voltage ratings in the available documentation. The NorComp 191-025-123R001 specifies 5A current rating without voltage specification.

Q: What packaging formats are available for these parts?

A: The TE Connectivity 5748146-4 is supplied in Bulk packaging. All Amphenol ICC substitutes (D25P91 series) and the NorComp 191-025-123R001 are supplied in Tray packaging.

Q: Are there differences in shell material finish between parts?

A: Yes. The TE Connectivity 5748146-4 features tin-plated steel shell. The Amphenol ICC D25P91 series parts feature tin-nickel plated steel shell. The NorComp 191-025-123R001 features nickel-plated steel shell. All finishes provide corrosion resistance and are compatible with gold-plated contacts.

Q: Which substitute part has the highest inventory availability?

A: D25P91C4GV00LF has 1271 units in stock, followed by D25P91C6PX00LF with 1104 units, NorComp 191-025-123R001 with 806 units, and D25P91C6GV00LF with 691 units.
