Key Parameters

Substitute Part Grouping Explanation

The PL71L-9 qualifies as a parametric equivalent to the PL71-9 based on identical specifications across all critical substitution criteria. The following parameters determine substitution eligibility:

Connector Style, Connector Type, Contact Termination, Shield Termination, Mounting Type, Frequency Maximum, Operating Temperature Range, Voltage Rating, Mating Cycles, Center Contact Material, Body Material, Body Finish, Center Contact Plating, RoHS Status, and Moisture Sensitivity Level are identical between the main part and substitute part.

Both parts belong to the same Series 70 product line, share the same base product number (PL71), and are compatible with the same cable groups (TWC-78-2, TWC-124-2). The substitute part maintains full electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both PL71-9 and PL71L-9 are Active products from the same manufacturer with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability. The PL71L-9 currently has higher stock levels (1006 pieces versus 738 pieces). Both parts maintain RoHS compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4010). Either part satisfies the same application requirements without modification to circuit design or mechanical assembly.

Frequently Asked Questions (FAQ)

Q: Can PL71L-9 be used as a direct replacement for PL71-9?

A: Yes. The PL71L-9 is a parametric equivalent with identical specifications across all electrical and mechanical parameters, including connector style, termination type, frequency rating, temperature range, voltage rating, and material composition.

Q: Are there any differences in mating compatibility?

A: No. Both parts are TRB Twinaxial/Triaxial male plug connectors with identical mounting type (free hanging in-line) and fastening type (threaded). They are compatible with the same cable groups (TWC-78-2, TWC-124-2).

Q: Do both parts meet the same compliance requirements?

A: Yes. Both PL71-9 and PL71L-9 are RoHS Compliant with identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. Moisture Sensitivity Level is 1 (Unlimited) for both parts.

Q: What is the difference between these part numbers?

A: The part numbers differ only in the suffix designation (PL71-9 versus PL71L-9). Both share the same base product number (PL71) and Series 70 classification. The functional and electrical specifications are identical.

Q: Which part should be selected based on availability?

A: Selection may be based on inventory requirements. PL71L-9 has higher current stock (1006 pieces) compared to PL71-9 (738 pieces). Both are Active products with equivalent lead times and supply reliability.
