Substitute Part Grouping Explanation

Substitution for the 76350-104-72 is determined by the following critical parameters:

Pitch and Position Count: All substitutes maintain 0.100" (2.54mm) mating pitch with 72 positions in a 2-row configuration
Mounting Configuration: All substitutes are through-hole, right-angle headers
Connector Style: All maintain board-to-board or board-to-cable compatibility
Contact Type: All use male pin contacts with solder termination
Fastening: All employ push-pull fastening mechanisms
Flammability: All meet UL94 V-0 material flammability requirements

The substitute parts listed below satisfy these core electrical and mechanical compatibility criteria. Variations in contact material, contact finish, insulation material, and operating temperature ranges are secondary parameters that do not prevent functional substitution when the primary criteria are met.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, addressing the obsolescence status of the 76350-104-72. Selection among substitutes should be based on the following factors:

RoHS Compliance: The Würth Elektronik 61307221021, Preci-Dip 802-V3-072-20-001101, and all Samtec TSW variants are ROHS3 compliant, whereas the original part is RoHS non-compliant. For new designs or applications requiring RoHS compliance, any of these active substitutes are suitable.

Product Availability: All substitute parts maintain active product status with current inventory levels ranging from 769 to 1146 pieces, ensuring procurement continuity.

Operating Temperature Range: The Preci-Dip 802-V3-072-20-001101 and Samtec TSW variants (except TSW-136-08-T-D-RA) support -55°C to 125°C operation, providing extended temperature capability compared to the original part. The Würth Elektronik 61307221021 operates from -40°C to 105°C.

Contact Finish Options: Samtec offers multiple contact finish configurations (gold or tin mating surfaces with gold or tin post finishes) through variants TSW-136-08-G-D-RA, TSW-136-08-L-D-RA, TSW-136-08-S-D-RA, and TSW-136-08-T-D-RA, allowing selection based on specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 76350-104-72 with any of the listed substitutes?

A: Yes. All listed substitutes maintain the critical electrical and mechanical parameters: 0.100" (2.54mm) pitch, 72 positions in 2 rows, through-hole right-angle mounting, male pin contacts, solder termination, and push-pull fastening. Physical board layout compatibility should be verified due to minor variations in insulation height and contact length specifications.

Q: What is the primary reason for finding substitutes for the 76350-104-72?

A: The original part is listed as obsolete. All substitute parts are active products with current manufacturing support and available inventory, ensuring long-term design viability and procurement reliability.

Q: Are there RoHS compliance differences between the original and substitute parts?

A: Yes. The 76350-104-72 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, making them suitable for applications requiring RoHS compliance.

Q: Do the substitute parts have different operating temperature ranges?

A: Yes. The original part does not specify an operating temperature range. The Preci-Dip 802-V3-072-20-001101 and most Samtec TSW variants operate from -55°C to 125°C, while the Würth Elektronik 61307221021 operates from -40°C to 105°C. The Samtec TSW-136-08-T-D-RA operates from -55°C to 105°C.

Q: What are the differences in contact finish options among the Samtec TSW variants?

A: The Samtec TSW series offers four variants with different contact finish combinations: TSW-136-08-G-D-RA (gold mating, gold post), TSW-136-08-L-D-RA (gold mating, tin post), TSW-136-08-S-D-RA (gold mating, tin post with thicker gold plating), and TSW-136-08-T-D-RA (tin mating, tin post). Selection depends on application-specific corrosion resistance and conductivity requirements.

Q: Are there physical dimension differences I should consider?

A: Minor variations exist in insulation height and contact length specifications. The original part and Würth Elektronik 61307221021 have 0.200" (5.08mm) insulation height, while Samtec TSW variants have 0.219" (5.56mm). Contact length specifications also vary slightly. PCB layout verification is recommended before final design release.

Q: Which substitute offers the best long-term availability?

A: All substitute parts are active products. Würth Elektronik, Preci-Dip, and Samtec are established manufacturers with ongoing production. Current inventory levels for all substitutes exceed 750 pieces, indicating stable supply chains.
