Engineering Selection Recommendations

Primary Recommendation: D15P91C4PL00LF

The D15P91C4PL00LF is the direct equivalent replacement for the obsolete D15P91C4PL00. Both parts maintain identical electrical ratings (5A per contact, 300V), mechanical configuration (15 position, 2 row, Shell Size 2 DA/A), and flange design (Housing/Shell M3). The D15P91C4PL00LF is active in production with RoHS compliance and tin-nickel plated steel shell finish, providing superior corrosion resistance compared to the original tin-plated finish.

Secondary Recommendations: L17TF Series (L17TF1510100, L17TF1510101, L17TF1510102, L17TF1510104, L17TF1510105, L17TF1510114, L17TF1510115)

The L17TF series connectors from Amphenol ICC Commercial Products provide functional substitutes when the reduced current rating of 3A per contact is acceptable for the application. All L17TF variants maintain the critical D-Sub 15 position configuration, press-fit termination, through-hole mounting, 300V voltage rating, and -55°C to 125°C operating temperature range. These parts are active in production with full RoHS compliance.

Selection among L17TF variants depends on flange feature requirements:

L17TF1510100: Unthreaded housing/shell
L17TF1510101: Housing/shell with 4-40 threaded holes
L17TF1510102: Mating side female screwlock (4-40)
L17TF1510104: Housing/shell with M3 threaded holes
L17TF1510105: Mating side female screwlock (M3)
L17TF1510114: Housing/shell M3 with board lock feature
L17TF1510115: Mating side female screwlock M3 with board lock feature

Frequently Asked Questions (FAQ)

Q: Can L17TF series connectors directly replace the D15P91C4PL00 in all applications?

A: L17TF series connectors are mechanically and electrically compatible for applications requiring 3A or less per contact. If your application requires the full 5A per contact rating, the D15P91C4PL00LF is the appropriate choice. Both maintain identical D-Sub 15 position configuration, press-fit termination, and operating temperature range.

Q: What is the difference between D15P91C4PL00 and D15P91C4PL00LF?

A: The D15P91C4PL00LF is the active production equivalent with improved shell finish (tin-nickel plated vs. tin plated) and RoHS compliance. Both parts maintain 5A per contact current rating, identical flange design (M3), and all critical electrical specifications. The D15P91C4PL00LF is recommended for new designs and obsolescence replacement.

Q: How do flange features affect connector selection?

A: Flange features determine mounting and mating interface configuration. Housing/shell variants (unthreaded, 4-40, M3) provide different fastening options for panel mounting. Mating side female screwlock variants include integrated locking mechanisms on the connector's mating interface. Select the flange feature matching your mechanical assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The D15P91C4PL00LF and all L17TF series variants (L17TF1510100, L17TF1510101, L17TF1510102, L17TF1510104, L17TF1510105, L17TF1510114, L17TF1510115) are RoHS compliant. The original D15P91C4PL00 is RoHS non-compliant.

Q: What is the difference between contact materials in these connectors?

A: The D15P91C4PL00 and D15P91C4PL00LF use phosphor bronze contacts. The L17TF series uses brass contacts. Both materials are suitable for signal-level applications at the specified voltage and current ratings. Contact material selection does not affect mechanical compatibility or mating interface performance.

Q: Can I use L17TF1510114 or L17TF1510115 if I need board lock features?

A: Yes. L17TF1510114 and L17TF1510115 include board lock features in addition to grounding indents. L17TF1510114 has housing/shell M3 flange, while L17TF1510115 has mating side female screwlock M3 flange. Both maintain all other electrical and mechanical specifications identical to other L17TF variants.

Q: What packaging is available for these connectors?

A: D15P91C4PL00LF and all L17TF series connectors are supplied in tray packaging. The original D15P91C4PL00 packaging information is not specified in the technical data.
