Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the 76350-104-72LF and meet the core electrical and mechanical requirements for board-to-board header applications at 0.100" (2.54mm) pitch with 72 positions in a 2-row configuration.

Primary Recommendation: The Würth Elektronik 61307221021 (WR-PHD series) is the manufacturer-recommended substitute. It maintains identical pitch, position count, and mounting configuration while offering active product status, ROHS3 compliance, and specified operating temperature range of -40°C to 105°C.

Alternative Selections by Application Requirements:

For applications requiring extended temperature operation to -55°C, the Preci-Dip 802-V3-072-20-001101 or Samtec TSW-136 series variants provide -55°C to 125°C operating range with ROHS3 compliance and MSL 1 rating.

For applications with specific contact finish requirements, Samtec TSW-136-08-G-D-RA and TSW-136-08-S-D-RA offer gold-plated mating contacts with phosphor bronze material, closely matching the original 76350-104-72LF specification. Samtec TSW-136-08-T-D-RA provides tin-plated contacts as an alternative.

All substitute parts carry UL94 V-0 flammability certification and are RoHS compliant, meeting standard regulatory requirements for electronic component applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 76350-104-72LF?

A: Yes. All listed parts meet the critical substitution parameters: 72-position header, 0.100" (2.54mm) pitch, 2-row configuration, through-hole right-angle mounting, solder termination, and push-pull fastening. Variations in contact material (phosphor bronze or brass), contact finish (gold or tin), and insulation material do not affect functional compatibility in standard board-to-board applications.

Q: What is the difference between the Preci-Dip 802-80-072-20-001101 and 802-V3-072-20-001101?

A: Both are Preci-Dip 802 series headers with identical mechanical specifications. The primary difference is contact finish: 802-80 features tin-plated mating contacts, while 802-V3 features gold-plated mating contacts with 29.5µin (0.75µm) thickness. Both support -55°C to 125°C operating temperature and ROHS3 compliance.

Q: How do the Samtec TSW-136 variants differ?

A: The TSW-136 series offers four variants distinguished by contact finish combinations. TSW-136-08-G-D-RA and TSW-136-08-S-D-RA feature gold-plated mating contacts (10.0µin and 30.0µin thickness respectively) with different post finishes. TSW-136-08-L-D-RA has gold mating contacts with tin post finish. TSW-136-08-T-D-RA features tin-plated contacts throughout. All maintain identical mechanical dimensions and electrical performance.

Q: Does the insulation height variation affect compatibility?

A: The 76350-104-72LF specifies 0.200" (5.08mm) insulation height. Most substitutes maintain this dimension. Samtec TSW-136 variants have 0.219" (5.56mm) insulation height. This minor variation does not affect functional compatibility in standard applications but should be verified against specific PCB layout constraints.

Q: Are there current or voltage rating differences I should consider?

A: The original 76350-104-72LF does not specify current or voltage ratings. Substitute parts with specified ratings (Würth Elektronik 61307221021: 3A, 250V; Preci-Dip 802 series: 3A, 150VDC) provide additional performance data. These ratings are suitable for standard logic-level and low-power signal applications.

Q: What is the significance of RoHS compliance differences?

A: The original part carries RoHS Compliant status. All substitute parts carry ROHS3 Compliant status, which represents current regulatory compliance and is fully backward compatible. ROHS3 compliance ensures the parts meet current EU and international environmental standards.

Q: Can I mix different substitute part numbers in the same assembly?

A: Yes. All listed parts are functionally equivalent and can be used interchangeably. However, for manufacturing consistency and traceability, using a single part number across an assembly is recommended.
