Key Parameters

Substitute Part Grouping Explanation

Substitution of the 40P3.0-JMCS-G-TF(N) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Plug with outer shroud contacts
• Electrical Interface: 40 positions at 0.020" (0.50mm) pitch, 2-row arrangement
• Mounting Technology: Surface mount compatibility
• Contact Material: Gold finish for signal integrity and corrosion resistance
• Physical Envelope: 3mm mated stacking height
• Environmental Compliance: RoHS compliance and MSL rating

The identified substitute part, 145046040630868+ from KYOCERA AVX, meets all these critical parameters and is classified as active product status, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The 145046040630868+ from KYOCERA AVX is the qualified substitute for the obsolete 40P3.0-JMCS-G-TF(N). Selection is based on the following engineering criteria:

Product Status & Availability: The substitute part carries active product status with 3016 units in current inventory, ensuring reliable supply chain access compared to the obsolete original part with limited remaining stock of 1065 units.

Compliance & Certification: Both parts maintain equivalent RoHS compliance (ROHS3 for the substitute represents current regulatory alignment). Both carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Electrical & Mechanical Compatibility: Identical specifications across connector type, position count, pitch, row configuration, mounting method, contact finish, and mated stacking height ensure direct functional substitution without circuit redesign or PCB layout modification.

Environmental Rating: Both parts maintain MSL 1 (Unlimited) moisture sensitivity, confirming equivalent handling and storage requirements.

Manufacturing Features: The substitute part includes pick-and-place and solder retention features, which enhance manufacturing process reliability without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the 145046040630868+ directly replace the 40P3.0-JMCS-G-TF(N) without PCB redesign?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting type, contact finish, and mated stacking height. The substitute part's height above board specification (0.091" / 2.30mm) is a documented parameter that does not affect compatibility with the original design envelope.

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

A: ROHS3 represents the current regulatory iteration of RoHS compliance. Both designations confirm the part meets lead-free and restricted substance requirements. The substitute part's ROHS3 status indicates current manufacturing compliance with the latest regulatory standards.

Q: Are there any packaging differences between the original and substitute part?

A: The substitute part is supplied in Cut Tape (CT) packaging. Verify that your assembly process accommodates this packaging format. The original part's packaging specification was not provided in the technical data.

Q: Do both parts have the same moisture sensitivity handling requirements?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply to both components.

Q: What certifications confirm these parts are equivalent?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory and tariff equivalence. RoHS compliance (RoHS and ROHS3) confirms environmental and hazardous substance compliance across both parts.
