Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 20P4.6-JMCS-G-TF(N) is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Type: Plug configuration with outer shroud contacts
• Position Count: Exactly 20 positions
• Contact Pitch: 0.020" (0.50mm)
• Row Configuration: 2 rows
• Mounting Technology: Surface mount (SMD)
• Contact Material: Gold plating
• Mated Stacking Height: 4.6mm
• Environmental Compliance: RoHS compliance and MSL rating

The substitute part 145046020635868+ from KYOCERA AVX meets all these criteria, confirming functional and mechanical equivalence for direct replacement applications.

Engineering Selection Recommendations

The 145046020635868+ from KYOCERA AVX is a direct functional equivalent to the obsolete 20P4.6-JMCS-G-TF(N). Selection of this substitute is supported by:

• Active Product Status: The KYOCERA AVX part is currently in active production, ensuring long-term availability and supply chain stability.
• Compliance Alignment: Both parts maintain equivalent RoHS compliance (ROHS3 represents an updated compliance standard) and identical MSL ratings, confirming suitability for the same environmental and manufacturing conditions.
• Electrical and Mechanical Equivalence: All critical parameters—position count, pitch, mounting type, contact finish, and stacking height—are identical, enabling direct substitution without circuit redesign or PCB layout modification.
• Inventory Availability: The substitute part maintains substantial stock levels (2927 pcs), supporting immediate procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 145046020635868+ be used as a direct replacement for the 20P4.6-JMCS-G-TF(N)?

A: Yes. Both parts share identical electrical and mechanical specifications: 20 positions, 0.020" (0.50mm) pitch, 2-row configuration, surface mount technology, gold contact finish, and 4.6mm mated stacking height. No circuit or PCB modifications are required.

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

A: ROHS3 represents the current iteration of RoHS compliance standards. Both designations confirm the part meets heavy metal and hazardous substance restrictions. The KYOCERA AVX part's ROHS3 status indicates compliance with the latest regulatory requirements.

Q: Are there packaging differences between these parts?

A: The JST part packaging information is not specified in the available data. The KYOCERA AVX substitute is supplied in Cut Tape (CT) packaging and includes Pick and Place and Solder Retention features, which are standard for surface mount production environments.

Q: Does the Height Above Board specification affect substitution?

A: The JST part's Height Above Board is not specified. The KYOCERA AVX part specifies 0.110" (2.80mm) Height Above Board. This measurement describes the connector's profile above the PCB surface and does not affect electrical or mechanical compatibility for standard applications.

Q: What is the significance of the MSL rating for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard conditions without special desiccant packaging or shelf-life limitations.
