L717DEF09POL2

Part Overview

The L717DEF09POL2 is a 9-position D-Sub plug connector manufactured by Amphenol ICC for signal applications. This connector features male pins with vertical through-hole solder termination, tin-plated steel shell, and gold-plated contacts. The product is active and maintains high availability with 933 units in stock.

Identifying equivalent and substitute parts is necessary when primary sources are unavailable, when design requirements change, or when alternative manufacturers offer improved availability or compliance certifications. Substitute parts must maintain compatibility across critical electrical and mechanical parameters, including pin count, shell size, contact finish, current rating, and operating temperature range.

Engineering Selection Recommendations

TE Connectivity AMP Connectors (1-338309-2, 1-5747871-x, 1-747871-x)

These connectors maintain full electrical compatibility with the L717DEF09POL2. The TE Connectivity AMPLIMITE series (HD-20 and HDP-20) meet or exceed all critical specifications. All ROHS3-compliant variants are recommended for new designs. The 1-747871-4 variant carries RoHS non-compliance status and should be used only in legacy applications without RoHS requirements. The 1-5747871-3 and 1-5747871-6 variants have undefined or unaffected REACH status; clarify requirements with procurement before selection.

NorComp Inc. (172-009-112R001, 172-E09-113R001, 172-E09-113R011, 172-E09-113R021)

NorComp connectors are substitutable with the following considerations: Product status varies, with 172-009-112R001 marked as obsolete. All NorComp variants operate at reduced current (5A vs. 7.5A) and temperature maximum (100°C vs. 125°C). These parts employ panel-mount configurations with unthreaded or board-side flanges, differing from the through-hole geometry of the L717DEF09POL2. Voltage ratings are not specified. NorComp parts are suitable for applications where lower current ratings and reduced operating temperature range are acceptable.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity parts directly replace the L717DEF09POL2?

The TE Connectivity AMPLIMITE connectors (1-338309-2, 1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, 1-747871-6) share identical D-Sub geometry and pin count. Electrical compatibility is maintained across all TE variants. Mechanical differences include flange configuration: the main part features an unthreaded housing flange, while most TE variants provide mating-side female screwlock flanges. Confirm flange interface compatibility with your application before substitution.

Q: Why do TE Connectivity parts have lower current ratings?

TE Connectivity variants are rated at 6A, compared to 7.5A for the L717DEF09POL2. This difference reflects manufacturing design specifications and does not indicate inferior quality. Applications requiring the full 7.5A rating must retain the Amphenol part or conduct thermal analysis to verify adequate performance at reduced ratings.

Q: Are NorComp parts viable substitutes?

NorComp connectors are electrically and mechanically compatible at the connector interface level. However, they carry lower electrical ratings (5A current, -50°C to 100°C operating range) and panel-mount configurations with flange variations. The 172-009-112R001 is obsolete and unavailable for new designs. NorComp substitution is limited to legacy applications or designs with reduced electrical requirements.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

ROHS3 represents the third iteration of the RoHS directive with updated restricted substance lists. Both certifications indicate compliance with hazardous substance restrictions for EU-distributed products. ROHS3-compliant parts are suitable for current designs. The designation difference reflects regulatory evolution and does not indicate performance variation.

Q: Are contact material differences significant?

The L717DEF09POL2 uses brass contacts, while the TE 1-338309-2 uses phosphor bronze. Both materials provide acceptable electrical conductivity and mechanical durability for signal-level applications. Contact material selection reflects manufacturer design preference. No performance degradation is expected from substitution.

Q: How do flange feature differences affect installation?

The L717DEF09POL2 provides an unthreaded housing flange without mating interface. Most TE variants include mating-side female screwlock flanges (4-40). NorComp variants feature board-side or unthreaded flanges. These differences require panel layout and mechanical assembly compatibility verification before substitution.

Q: Which substitute offers best availability?

TE Connectivity 1-5747871-3 shows highest inventory at 4,832 units. The L717DEF09POL2 maintains 933 units. All listed TE and active NorComp variants provide adequate stock levels for standard procurement timelines.
